(97) From Table 4 and Table 5, in Comparative example 1, a large amount of polyvinyl alcohol was used as the film-forming material without adding plant starch. It can be seen from the test results that the biodegradation rate of the detergent tablet is only 41%, which is much lower than the standard requirement of 60%, and it is difficult to meet the requirements of environmental protection. In Comparative example 2, a small amount of polyvinyl alcohol was used as the film-forming material and plant starch was added. It can be seen from the test results that the biodegradation rate of the detergent tablet reaches the standard, but the overall stability of the detergent tablet is low and the practicability is affected. In Example 6, an appropriate amount of polyvinyl alcohol was mixed with plant starch. It can be seen from the test results that not only the biodegradation rate of the detergent tablet exceeds 60%, but also the overall stability is better and the detergency is improved. In addition, by adjusting the proportion of the raw materials of the detergent tablet within the range of Examples 1 to 7, detergent tablets with good comprehensive performance are still obtained.

(98) Compared with Comparative examples 3 to 4, in Example 6, polyvinyl alcohol with appropriate polymerization degree and molecular weight was selected, the biodegradation rate and overall stability of the detergent tablet are balanced better. In addition, it was also found that when the polymerization degree and molecular weight of polyvinyl alcohol is too large, the dissolution rate of the detergent tablet is low, and there is residue after washing. Compared with

(99) Comparative example 5, in Example 6, the addition of maltodextrin as a film-forming agent significantly improved the overall stability of the detergent tablet.

(100) Compared with Example 5, in Example 6 and Example 7, the weight ratio of the polyvinyl alcohol to the plant starch was controlled as 1:(1.5-3), so that the detergent tablet had better detergency and moisture resistance stability.

(101) Compared with Examples 8 to 13, in Examples 6 and 14, the plant starch was combination of pea starch and corn starch, so that the detergent tablet had better overall stability; the detergency and stability were well balanced; and the use effect of the detergent tablet was better.

(102) Compared with Example 6, in Example 15, rhamnolipid and sophorolipid were added, and the biodegradation rate and detergency of the detergent tablet were both improved; in examples 16 to 20, the composition and proportion of the surfactant were adjusted; it was found that the detergency of detergent tablet could be well improved and the biodegradation rate could be further improved by the combination of coco-sulfate and fatty acid methyl ester ethoxy sodium sulfonate, the combination of modified oil ethoxylate and fatty alcohol polyoxyethylene ether, and the combination of rhamnolipid and sophorolipid.

(103) Example 1 of the present application also discloses a tableting equipment for an environmental friendly detergent tablet.

(104) As shown in FIG. 1, an tableting equipment for the environmental friendly detergent tablet includes a frame, a molding device 1, a coating device 8, an advancing device 2, an adjusting device 3, a slicing device 4, and an discharging device 5. The frame is configured to support and install the above devices. Specifically, the frame includes a first frame 7, a second frame 71, a third frame 72, and a fourth frame 73. The molding device 1 and the coating device 8 are installed on the first frame 7; the advancing device 2 and the adjusting device 3 are installed on the second frame 71; the slicing device 4 is installed on the third frame 72; and the discharging device 5 is installed on the fourth frame 73. The mixed materials passes through the molding device 1, the coating device 8, the advancing device 2, the adjusting device 3, the slicing device 4, and the discharging device 5 in sequence to obtain the finished product of the tablet.

(105) As shown in FIG. 2, the molding device 1 includes a trough 11, a drying-forming roller 12, a feeding roller and a forming driver. The trough 11 is arranged in the first frame 7. The trough 11 is configured to accommodate the mixed materials. The feeding roller is rotatably installed on the trough 11, and the surface of the feeding roller is in contact with the mixed materials. The drying-forming roller 12 is rotatably installed to the first frame 7, and the drying-forming roller 12 is arranged above the trough 11. The drying-forming roller 12 and the feeding roller are coaxially arranged with a gap between them. A heating device is provided inside the drying-forming roller 12, or a heating device is connected outside the drying-forming roller 12. The heating device may be a device with heating function such as a heating rod or a steam heater, so that the surface of the drying-forming roller 12 has a certain temperature.

(106) The forming driver is fixedly installed on the first frame 7. The forming driver is in transmission connection with the drying-forming roller 12 and the feeding roller, and the forming driver is configured to drive the drying-forming roller 12 and the feeding roller to rotate.

(107) In this example, the forming driver is a combination of motor and gearbox. During the rotation of the feeding roller, the mixed materials is driven to leave the trough 11 continuously. Meanwhile, the feeding roller drives the mixed materials to be coated on the surface of the drying-forming roller 12. The heat on the surface of the drying-forming roller 12 makes the moisture of the mixed materials evaporate, forming a solid semi-finished product.

(108) The coating device 8 includes an enzyme formulation tank 81, a first coating roller 82, a second coating roller 83, and an coating driver.

The first coating roller 82 is in contact with the bio-enzyme formulation; the first coating roller 82 is close to the second coating roller 83; and the second coating roller 83 is configured to coat the bio-enzyme formulation to the solid semi-finished product. The addition amount of the bio-enzyme formulation is controlled by adjusting the degree to which the first coating roller 82 enters the bio-enzyme formulation tank 81 and the distance between the first coating roller 82 and the second coating roller 83.

(109) The coating device driver is in transmission connection with the first coating roller 82 and the second coating roller 83. In this example, the coating device driver is a combination of a motor and a gearbox. The coating device driver drives the first coating roller 82 and the second coating roller 83 to rotate, thereby driving the bio-enzyme formulation to continuously leave the enzyme formulation tank 81 and be attached to the surface of the first coating roller 82. The first coating roller 82 transfers the bio-enzyme formulation to the second coating roller 83, and the second coating roller 83 then applies the bio-enzyme formulation to the solid semi-finished product, so that the bio-enzyme formulation is attached to the detergent tablet.

(110) The advancing device 2 includes an advancing roller 21 and an advancing driver 22. The advancing roller 21 is rotatably installed on the second frame 71; the advancing driver 22 is fixedly installed on the second frame 71; and the molding driver is in transmission connection with the advancing roller 21 and configured to drive the advancing roller 21 to rotate. In this example, the advancing driver 22 is a combination of a motor and a gearbox, and the advancing roller 21 rotates under the driving action of the advancing driving member 22. The solid semi-finished product is wound around the advancing roller 21 after leaving the drying-forming roller 12. The advancing roller 21 generates a force for the forward movement of the solid semi-finished product, so that the solid semi-finished product enters the adjusting device 3.

(111) The adjusting device 3 includes a first guide roller 31, a second guide roller 32, an adjusting rod 33, and an adjusting roller 34. The first guide roller 31, the second guide roller 32, and the adjusting rod 33 are all rotatably installed on the second frame 71. Two adjusting rods 33 are provided. The adjusting roller 34 is rotatably installed between the two adjusting rods 33. The adjusting roller 34 is arranged between the first guide roller 31 and the second guide roller 32, and the installation height of the adjusting roller 34 is lower than the installation height of the first guide roller 31 and the second guide roller 32. The solid semi-finished product is wound around the first guide roller 31, the adjustment roller 34, and the second guide roller 32 in sequence in the conveying direction, and then enters the slicing device 4. An embossing roller 35 is rotatably installed on the second frame 71. The embossing roller 35 is parallel to the first guide roller 31. A pattern is provided on the surface of the embossing roller 35. The embossing roller 35 and the first guide roller 31 jointly extrude the solid semi-finished product, and the pattern can be printed on the surface of the solid semi-finished product.

(112) Specifically, the installation height of the second guide roller 32 is lower than the installation height of the first guide roller 31. Additionally, the adjustment roller 34 can rotate freely relative to the adjusting rod 33, and the adjusting rod 33 can rotate freely relative to the second frame 71. Therefore, when the solid semi-finished product is tensioned, the adjusting rod 33 will deviate from the height direction and form an angle with the height direction.

(113) In the present application, the slicing device 4 performs a cutting mode combining vertical cutting and transverse cutting on the solid semi-finished product. In particular, transverse cutting refers to cutting in the direction perpendicular to the conveying direction of the solid semi-finished product. In order to ensure that the forward conveying of the solid semi-finished product will not affect the transverse cutting, the solid semi-finished product of the present application advances intermittently in the slicing device 4, and the transverse cutting is performed only when the solid semi-finished product stops advancing.

(114) As shown in FIG. 2 and FIG. 3, in order to realize the above cutting mode, the second frame 71 is provided with an angle sensor 36. The angle sensor 36 may obtain the rotation angle of the adjusting rod 33. The angle sensor 36 is connected in communication with a controller. In particular, the controller is a PLC controller, which can control the operation of the tableting equipment, including the operation of the slicing device 4.

(115) With the continuous advancing of the solid semi-finished product passing through the advancing device 2, there are more solid semi-finished product in the adjusting device 3; the tension force applied by the winding of the solid semi-finished product to the adjusting roller 34 is reduced, and the adjusting rod 33 swings downward under its gravity. When the adjusting rod 33 swings to a predetermined angle, the angle sensor 36 is triggered, and the slicing device 4 is controlled by the controller to operate, driving the solid semi-finished product to be transported to the slicing device 4. At this time, there are fewer solid semi-finished product in the adjusting device 3, the tension force applied by the winding of the solid semi-finished product to of the adjusting roller 34 is increased, the regulating roller 34 is tensioned and the regulating rod 33 swings upward; the regulating rod 33 returns to a predetermined angle; and the angle sensor 36 is triggered again to stop the operation of the slicing device 4, to control the conveying state of the solid semi-finished product, so as to realize the intermittent advance of the solid semi-finished product, and facilitate the transverse cutting of the solid semi-finished product.

(116) The slicing device 4 includes a transverse cutting mechanism 42, a vertical cutting mechanism 41, a feeding conveyor belt 44 and a downward pressing and feeding mechanism 43.

When the lifting cylinder 432 operates, the pressing plate 431 is pressed down, then the solid semi-finished product is pressed between the feeding conveyor belt 44 and the pressing plate 431, so that the feeding conveyor belt 44 and the pressing plate 431 are relatively stationary. In other examples, the lifting assembly may also be an motor-driven push-rod, a gear 435 and rack 434 transmission structure, and a leading screw and slide block transmission structure.

Both ends of the mounting plate 433 are fixedly connected to the two racks 434, respectively, and the lifting cylinder 432 is installed on the mounting plate 433. When the translation motor 436 operates, the gear 435 cooperates with the rack 434 to drive the mounting plate 433 to translate and drive the pressing plate 431 to translate, and cooperates with the feeding conveyor belt 44 and the pressing plate 431 to press the solid semi-finished product, so that the feeding conveyor belt 44 rotates and drives the solid semi-finished product to be conveyed forward. In other examples, the translation assembly may also be a cylinder, an motor-driven push-rod and a leading screw and slide block transmission structure. For example, a translation cylinder is provided on the third frame 72, the output end of the translation cylinder moves in the conveying direction of the solid semi-finished product, and the output end of the translation cylinder is connected to the mounting plate 433.

(120) Under the cooperation of the lifting assembly and the translation assembly, the pressing plate 431 drives the solid semi-finished product to move forward for a certain distance, and then the pressing plate 431 rises and is translated to the original position under the action of the lifting assembly and the translation assembly, so as to carry out the next pressing and feeding. The controller is connected in communication with the lifting cylinder 432 and the translation motor 436. The lifting cylinder 432 and the translation motor 436 are started or stopped or change the output direction according to the signal of the angle sensor 36, to realize the intermittent advance of the solid semi-finished product.
