[0036] Referring to FIGS. 2 and 3, a manufacturing method for a light-colored full-shading curtain cloth includes the steps; [0037] S01, manufacturing a greige cloth, performing weaving by a weaving machine, and simultaneously weaving a shading material into a greige cloth of a shading layer C by the weaving machine; [0038] S02, the manufacturing of a curtain cloth outer layer A, a curtain cloth inner layer B, and a shading layer C, cutting the greige cloth of the inner layer and outer layer of the curtain cloth to obtain a curtain cloth outer layer A and a curtain cloth inner layer B of a preset size, and cutting the greige cloth of the shading layer C to obtain a shading layer C of the preset size; [0039] S03, cleaning the cloth material, and placing the curtain cloth outer layer A, the curtain cloth inner layer B, and the shading layer C of the preset size into water for immersion cleaning for removing impurities attached on the outer side; [0040] S04, drying and rolling the cloth material, respectively placing the cleaned curtain cloth outer layer A, curtain cloth inner layer B, and shading layer C into a drying device for drying, and respectively rolling the dried curtain cloth outer layer A, curtain cloth inner layer B, and shading layer C; [0041] S05, the transfer and the secondary drying of the cloth material, performing contacting transfer on the curtain cloth outer layer A and the curtain cloth inner layer B by using the pre-mounted turning component 1, and performing the secondary drying treatment on the curtain cloth outer layer A and the curtain cloth inner layer B by using the secondary drying mechanism 2 built in the turning component; [0042] S06, the bonding between a plurality layers of cloth materials, applying glue to the gap at the outer edge of the curtain cloth outer layer A and the curtain cloth inner layer B for bonding the curtain cloth outer layer A, the curtain cloth inner layer B, and the shading layer C; [0043] S07, rolling, performing rolling on the curtain cloth outer layer A, the curtain cloth inner layer B, and the shading layer C bonded together; and [0044] S08, painting, painting the coating layer D on the outer side of the curtain cloth outer layer.

[0045] In this solution, the greige cloth of the curtain cloth is manufactured first, and then the greige cloth can be cut into a suitable size to meet the size of the curtain required, and then the same is cleaned and dried, and then the three-layer fabric of the curtain cloth outer layer A, the curtain cloth inner layer B, and the shading layer C is subjected to a bonding operation; during the bonding, since there would be a situation where the local fabric would be dried thoroughly, this situation would affect the subsequent application of the coating layer D, and the inner layer and outer layer of the curtain cloth and the outer side of the shading layer C are transferred and simultaneously subjected to the secondary drying operation by means of the designed secondary drying mechanism 2 cooperating with the turning component 1, thereby avoiding partial undried curtain cloth outer layer A, curtain cloth inner layer B, and shading layer C.

[0046] At the same time, with reference to FIGS. 1-5, the illustration comprises a turning component 1 and a secondary drying mechanism 2 in step S05; the turning component 1 comprises two turning rolls 3 and two side plates 4; the two turning rolls 3 are of a hollow pipe structure and are respectively in contact with the curtain cloth outer layer A and the curtain cloth inner layer B; two ends of the two turning rolls 3 are fixedly in communication with a connecting pipe 5, and the connecting pipe 5 is rotatably connected to the side plate 4; a plurality of rows of air blowing openings 6 is provided at equal angles on the outer side of the turning roll 3, and an occluding assembly 7 is correspondingly mounted in each row of air blowing openings 6; one of the side plates 4 is mounted with a drive member 8 for rotating the turning roll 3, and the other side plate 4 is mounted with an adjustment member 9 for adjusting the form of the occluding assembly 7; the outer end of the connecting pipe 5 is rotatably butted with an air transferring pipe 10 for inflating dry hot air, and the secondary drying mechanism 2 is mounted between the two side plates 4.

[0047] It needs to be noted that the air transferring pipe 10 is butted with an external inflation device, and dry hot air is introduced into the turning roll 3 through the air transferring pipe 10. The turning roll 3 is a hollow pipe, and the air blowing opening 6 on the turning roll 3 is blocked by the occluding assembly 7. The injection of dry hot air from the outside will cause high pressure inside the turning roll 3. Then, one row of occluding assemblies 7 is opened through the adjustment member 9, so that one row of air blowing openings 6 that come into contact with the curtain cloth outer layer A and the curtain cloth inner layer B can blow air hot air, thereby performing secondary drying on the curtain cloth outer layer A and the curtain cloth inner layer B.

[0048] It further needs to be noted that through the action of the drive member 8, a plurality of rows of occluding assemblies 7 is driven to successively contact with the adjustment member 9), and the air blowing openings 6 are successively opened, so as to meet the rotation of the turning roll 3, and at the same time, ensure that each time the air can be blown towards the curtain cloth outer layer A and the curtain cloth inner layer B for drying.

[0049] With reference to FIGS. 6 and 7, the occluding assembly 7 in the figure comprises an adjustment lever 11 and a plurality of occluding protrusions 12. The top air blowing openings 6 of the occluding protrusions 12 are inserted into each other, an adjustment seat 13 is fixed at the bottom, an adjustment opening 14 is opened in the adjustment seat 13, and the cross-sectional shape of the adjustment opening 14 is a right-angled trapezoid. Two ends of the adjustment lever 11 slide through two ends of the turning roll 3 and are inserted into the adjustment openings 14 in one row of the adjustment seats 13, an adjustment inclined block 15 adapted to the bevel end of the adjustment opening 14 is fixed on the outer side of the adjustment lever 11, and a slide bar 16 fixed to the inner wall of the turning roll 3 is fixed on the outer side of the occluding protrusions 12.

[0050] Meanwhile, referring to FIGS. 5-7, the adjustment member 9 shown in the figures comprises a hemispherical block 17 fixed at the outer ends of the plurality of adjustment levers 11 and an adjustment disk 18 fixed at the outer side of one of the side plates 4. The adjustment disk 18 is rotatably sleeved with one of the connecting pipes 5, an arc-shaped protrusion 19 is fixed at the bottom of one side of the adjustment disk 18 near the turning roll 3, the arc-shaped protrusion 19 is fitted with the hemispherical block 17, and the outer sides of the plurality of adjustment levers 11 are all sleeved with an extrusion spring 20 abutting against the hemispherical block 17 and the outer wall of the turning roll 3.

[0051] Meanwhile, referring to FIG. 4, the illustrated drive member 8 includes a drive motor 22 fixed to the side plate 4. The output end of the drive motor 22 is fixed with a drive gear 23, and the outer side of the connecting pipe 5 is fixed with a transmission gear 24 that meshes with the drive gear 23.

[0052] The principle of adjusting the form of the occluding assembly 7 by means of the adjustment member 9 is as follows: firstly, the drive motor 22 rotates, driving the drive gear 23 to follow the rotation, and causing the meshing transmission gear 24 to rotate, thus driving the connecting pipe 5 and the turning roll 3 to rotate, thereby, through the turning roll 3, enabling the inner layer and outer layer of the curtain cloth to turn and move.

[0053] Secondly, while the turning roll 3 rotates, a plurality of adjustment levers 11 inside the turning roll 3 will follow the rotation; when the hemispherical block 17 at one end of the adjustment lever 11 contacts with the arc-shaped protrusion 19 at the bottom of the adjustment plate 18, the adjustment lever 11 will be extruded to move towards the inside of the turning roll 3, so that the adjustment inclined block 15 on the outer side of the adjustment lever 11 abuts against the bevel in the adjustment opening 14, and the adjustment inclined block 15 moves with the adjustment lever 11. At that, the adjustment opening 14 can be jacked up, as shown in FIG. 7, thereby driving the corresponding movement of the adjustment seat 13 and the occluding protrusion 12 such that the occluding protrusion 12 is disengaged from the air blowing opening 6. Therefore, the air in the turning roll 3 is disinflated outward through the opened air blowing opening 6, and air blowing can be performed on the inner layer and outer layer of the curtain cloth fitted to the outer side of the turning roll 3. By the dry hot air, the remaining undried area on the inner layer and outer layer of the curtain cloth can be subjected to the secondary drying treatment.

[0054] It is worth noting that when the adjustment lever 11 is disengaged from the arc-shaped protrusion 19, the hemispherical block 17 is always fitted with the outer side wall of the adjustment disk 18 by the action of the extrusion spring 20; at the same time, in order to stabilize the fitting of the extrusion spring 20 with the outer wall of the turning roll 3, a grommet 21 is sheathed on the outer side of the adjustment lever 11 abutting against the extrusion spring 20.

[0055] In this solution, with reference to FIGS. 3 to 5, 8 and 9, two secondary drying mechanisms 2 are provided in the figure, and the two are distributed on two sides of the shading layer C; the secondary drying mechanism 2 comprises a drive rod 25 and a docking frame 26 in contact with the shading layer C; two ends of the drive rod 25 are rotatably docked with the two side plates 4, and a rotational motor 27 for the rotation of the drive rod 25 is fixed on the outer side of one of the side plates 4; two cylinders 28 are rotatably mounted on the outer side of the drive rod 25, and one end of the two cylinders 28 is fixedly communicated with an air suction pipe 29, and a plurality of air suction holes 30 is provided on the outer side of the air suction pipe 29; an exhaust pipe 31 in communication with the docking frame 26 is fixed to the other end, an exhaust fan 32 for sucking air by the air suction pipe 29 is fixed to the outer wall of the outer-side cylinder 28 where the drive rod 25 is located, and a mounting pipe 33 fixed the side plate 4 is fixed to the outer side of the cylinder 28.

[0056] A connecting column 50 fixed to the side plate 4 is fixed to two ends of the docking frame 26, an exhaust port 34 is provided at the bottom of the docking frame 26, a heating strip 35 is fixed in the docking frame 26, two contact rolls 36 are fixed between the two side plates 4, and the two contact rolls 36 are distributed on the outer side of the two docking frames 26 and are in contact with the shading layer C.

[0057] The principle of secondary drying the shading layer C is as follows: firstly, the shading layer C passes through between two secondary drying mechanisms 2, as shown in FIG. 3, and then the drive rod 25 is rotated by the rotation of a rotational motor 27 on the outer side, so that the exhaust fan 32 is rotated; at that, the front end of the cylinder 28 performs negative pressure suction, and the rear end performs venting, and the outside air is absorbed via the air suction pipe 29; at the same time, the air is passed into the docking frame 26 via the exhaust pipe 31, the air is dried and heated via the heating strip 35 in the docking frame 26, and then is directly disinflated into the outer side of the shading layer C via the exhaust port 34, and the outer side of the shading layer C is subjected to secondary drying such that undried areas are excluded and the quality of subsequent coating and gluing is improved.

[0058] It further needs to be noted that two air suction pipes 29 are provided and are respectively located on the outer side of the turning roll 3; by means of the distribution of the positions of the air suction pipes 29, as shown in FIGS. 3, 4, and 8, both of the two air suction pipes 29 are close to the inner layer and outer layer of the curtain cloth, so as to efficiently absorb the hot air passing through the inner layer and outer layer of the curtain cloth, thereby reducing energy consumption; at the same time, it can also prevent hot air from being disinflated and condensed into water mist when it cools down, which would otherwise blow towards the shading layer C, making it damp and affecting the quality of the subsequent coating and gluing.

[0059] A method for performing secondary drying on the inner layer and outer layer of the curtain cloth and the shading layer C is as follows: [0060] in the first step, the inner layer and outer layer of the curtain cloth and the shading layer C are inserted according to FIGS. 1 and 2, so that the inner layer and outer layer of the curtain cloth are located between two turning rolls 3, and the shading layer C is located between two secondary drying mechanisms 2; [0061] in the second step, dry air is inflated into the turning roll 3 via an external inflation device, and at the same time, the bottom-most occluding assembly 7 is opened via the adjustment member 9, so as to realize the secondary drying of the inner layer and outer layer of the curtain cloth; [0062] in the third step, the air permeated from the inner layer and outer layer of the curtain cloth is absorbed by the two secondary drying mechanisms 2, heated and then blown to the shading layer C to achieve secondary drying of the shading layer C.

[0063] In this solution, with reference to FIG. 12, a light-colored full-shading curtain cloth is shown in the figure, comprising the curtain cloth outer layer A, the curtain cloth inner layer B, and the shading layer C. The cloth base layers of the curtain cloth outer layer A and the curtain cloth inner layer B are formed by co-weaving cotton linen fibers and bamboo charcoal fibers, and the shading layer C is formed by co-weaving polyester fibers, acrylic fibers, and graphene fibers.

[0064] The shading layer C is located between the curtain cloth outer layer A and the curtain cloth inner layer B, the widths of the curtain cloth outer layer A and the curtain cloth inner layer B are consistent, and the width of the shading layer C is less than the widths of the curtain cloth outer layer A and the curtain cloth inner layer B.

[0065] The outer side of the curtain cloth outer layer A is provided with a coating layer D, and the outer edges of the curtain cloth outer layer A and the curtain cloth inner layer B are bonded to the shading layer C via gluing.

[0066] It needs to be noted that in the designed curtain cloth outer layer A, curtain cloth inner layer B, and inner shading layer C, a shading effect is performed through the inner shading layer C. The curtain cloth outer layer A, the curtain cloth inner layer B, and the inner shading layer C are weaved with a light-colored material, and at the same time, a coating layer D is painted on the outer side of the curtain cloth outer layer A, so that it can provide a shading and thermal insulation effect on the curtain cloth outer layer A, thereby enabling the curtain body to achieve shading and thermal insulation functions.

[0067] It further needs to be noted that the widths of the curtain cloth outer layer A and the curtain cloth inner layer B are consistent, and the width of the shading layer C is less than the widths of the curtain cloth outer layer A and the curtain cloth inner layer B so that the design mainly satisfies that situation that when the glue is pressed fit, and part of the glue will diffuse outwards due to the extrusion; at this time, it only requires the glue to be smeared on two sides of the shading layer C and then pressing fit is performed, so as to satisfy the pressing fit among the curtain cloth outer layer A, the shading layer C, and the curtain cloth inner layer B, and the glue which is extruded to achieve diffusion overflow is mainly on two sides of the curtain cloth outer layer A and the curtain cloth inner layer B so as to avoid the glue overflowing on the end face.

[0068] With reference to FIGS. 10 and 11, the implementation mode further explains embodiment 1, two support plates 37 are provided at the front ends of the two side plates 4 in the figure, and two groups of guide posts 38 are fixed between the two support plates 37. The two groups of guide posts 38 are symmetrically distributed on two sides of the shading layer C, and are used for the curtain cloth outer layer A and the curtain cloth inner layer B to be fitted with the shading layer C, and each group of guide posts 38 is composed of two guide posts 38, and the shading layer C is fitted with the outer sides of the two guide posts 38 in sequence.

[0069] Four distraction pieces 39 are fixed between the two support plates 37 and symmetrically distributed on two sides of the shading layer C, each distraction piece 39 comprises two fixing plates 40 and two rotating shafts 41 rotatably mounted between the two fixing plates 40, a rotational gear 42 is fixed on the outer side of the two rotating shafts 41, and the outer sides of the two rotational gears 42 are meshed and sleeved with a toothed belt 43; a distraction motor 44 is fixed on the outer side of one of the fixing plates 40, and an output end of the distraction motor 44 is fixed with one end of the rotating shaft 41.

[0070] It needs to be noted that when the distraction motor 44 rotates, it drives the rotating shaft 41 and the rotational gear 42 to rotate; under the action of the toothed belt 43, the two rotational gears 42 rotate synchronously, thereby driving a plurality of contact columns 45 to move outwards successively; at that, two sides of the inner layer and outer layer of the curtain cloth abutting against the contact column 45 have one outward pulling force, thereby enabling the inner layer and outer layer of the curtain cloth to spread outwards, avoiding the occurrence of a skew folding phenomenon caused by dry air blowing, and improving the subsequent bonding quality.

[0071] It further needs to be noted that a plurality of contact columns 45 is fixed at equal intervals on the outer side of the toothed belt 43; at the same time, the contact columns 45 are made of a rubber material; the contact columns 45 are in contact with the inner layer and outer layer of the curtain cloth so as to be able to contact at multiple points and faces; compared with the whole face contact on the outer side of the toothed belt 43, it can not only play the function of pulling the inner layer and outer layer of the curtain outwards, but also do not affect the normal movement and transportation.
