In the present embodiment, the first driver 111 is a motor fixedly mounted on the mounting frame 1, and the conveyor wheel 11 is fixedly connected to the output end of the first driver 111. The first clamping wheel 12 is slidably mounted on the mounting frame 1 in a direction toward or away from the conveyor wheel 11, and a fourth driver 121 for driving the first clamping wheel 12 to slide is mounted on the mounting frame 1. In the present embodiment, the fourth driver 121 is a cylinder, the fourth driver 121 is fixedly mounted on the mounting frame 1, and a piston rod of the fourth driver 121 is fixedly connected to the first clamping wheel 12.

(8) A guide element 14 is fixedly mounted on the mounting frame 1 at an input end of the gap 13 and is provided with a guide hole 141, and the cross-sectional area of the guide hole 141 gradually decreases towards the mounting frame 1. A worker places the end of the graphite strip 46 into the guide element 14, and the graphite strip 46 extends into the guide element 14 and out of the tapered guide hole 141, so as to stably extend into the gap 13. At this time, the worker may activate the fourth driver 121 to drive the first clamping wheel 12 to slide to stably clamp the graphite strip 46 with the conveyor wheel 11, thereby transporting the graphite strip 46.

(9) The mounting frame 1 is configured with a mounting hole 15 through which the graphite strip 46 passes through the gap 13 in a vertical direction. The guide assembly 2 includes a guide column 21 slidably mounted on the mounting frame 1 and a second driver 22 on the mounting frame 1 for driving the guide column 21 to slide on the mounting frame 1. In the present embodiment, the second driver 22 is a cylinder, the piston rod of the second driver 22 is fixedly connected to the guide column 21, and a guide plate 23 is provided at an end of the guide column 21 out of the mounting frame 1 at the bottom, and the guide plate 23 is configured for guiding a graphite strip 46 out of the mounting frame 1 to cooperate with an input end of the gasket machine of the conveying device. A side of the guide plate 23 away from the guide column 21 directly faces the input end of the gasket machine. After passing through the gap 13, the graphite strip 46 passes through the mounting hole 15 and reaches the bottom of the mounting frame 1 and abuts against the guide plate 23. The worker starts the second driver 22 at this time to drive the guide column 21 to slide, so as to move the guide plate 23 towards the raw material input end of the gasket machine, and meanwhile, the conveyor wheel 11 together with the first clamping wheel 12 convey the graphite strip 46, so that the guide plate 23 and the graphite strip 46 move synchronously, so as to accurately convey the graphite strip 46 to the input end of the gasket machine along a sliding direction of the guide column 21.

(10) Referring to FIG. 2, the mounting frame 1 is provided with a cutter 31 between the mounting hole 15 and the guide plate 23, and the cutter 31 is slidably mounted on the mounting frame 1 along a direction perpendicular to the transport direction of the graphite strip 46 at the mounting hole 15. The mounting frame 1 is provided with a third driver 32 for driving the cutter 31 to slide on the mounting frame 1, the third driver 32 is a cylinder and is fixedly mounted on the mounting frame 1, and a piston rod of the third driver 32 is fixedly connected to the cutter 31. The graphite strip 46 may be quickly cut off by the cutter 31, so that the worker may handle the next gasket.

(11) The implementation principle of the automatic graphite conveying device in the embodiments of the present application is as follows. A worker first puts the graphite strip 46 into the guide element 14, after the graphite strip is in place, the first driver 111 is activated to drive the conveyor wheel 11 to rotate, so that the graphite strip stably passes through the mounting hole 15 and moves to the guide plate 23 under the clamping of the first clamping wheel 12, and the second driver 22 is activated to drive the guide plate 23 to slide, so as to accurately convey the graphite coil fitting tightly to the guide plate 23 to the gasket machine.

(12) When the winding operation of one gasket is completed, the third driver 32 is activated to drive the cutter 31 to slide on the mounting frame 1, so as to cut the graphite strip 46, and the worker applies the next segment of the graphite strip 46 to the next gasket.

(13) The embodiments of the present application also disclose a winding machine for a spiral wound gasket, and referring to FIG. 3, the winding machine for the spiral wound gasket includes a stander 4, a graphite tray 42, a rotary wheel 41, a welding wheel 43 and a second clamping wheel 44. The rotary wheel 41, the welding wheel 43 and the second clamping wheel 44 are all rotatably mounted on the stander 4. The rotary wheel 41 is used for mounting a gasket body 45, and the rotary wheel 41 clamps the gasket body 45 by the movement of the wheel body.

(14) The graphite strip 46 and a steel strip 47 overlapping each other are wound around the gasket body 45, and the second clamping wheel 44 abuts against the steel strip 47 on the gasket body 45 on the rotary wheel 41. The welding wheel 43 is energized, then abuts against the steel strip 47 wound around the gasket body 45 and fixes the steel strip 47 by welding. The graphite tray 42 is fixedly mounted on the stander 4, and the conveying device is mounted on the stander 4 for conveying the graphite strip 46 on the graphite tray 42 to the gasket body 45 on the rotary wheel 41.

(15) Referring to FIG. 3, a steel strip tray is mounted on the stander 4. The stander 4 is fixedly provided with a guide frame 5 between the steel strip tray and the rotary wheel 41, a guide sleeve 51 is slidably mounted inside the guide frame 5, and a sixth driver 52 for driving the guide sleeve 51 to slide on the guide frame 5 is fixedly mounted outside the guide frame 5. In the present embodiment, the sixth driver 52 is a cylinder, and a piston rod of the sixth driver 52 is fixedly connected to the guide sleeve 51. The steel strip 47 passes through the guide sleeve 51 and directly faces the rotary wheel 41, and the steel strip 47 is accurately transported to the gasket body 45 by the slidable guide sleeve 51.

(16) Before winding the graphite strip 46 and the steel strip 47 around the gasket body 45, the worker takes out the graphite strip 46 from the graphite tray 42 and places the graphite strip 46 on the conveying device while taking out the steel strip 47 from the steel strip tray and winding it around the gasket body 45 through the guide sleeve 51, and then presses the gasket body 45 against the steel strip 47 with the welding wheel 43 to weld the steel strip 47 onto the gasket body 45. The worker then activates the conveying device to convey the graphite strip 46 to the gasket body 45 and co-wind with the steel strip 47 around the gasket body 45, and continues to weld the steel strip 47 to fix the graphite strip 46.

(17) Referring to FIGS. 4 and 5, the stander 4 is provided with storage racks 6 at two sides in a vertical direction at a rotary shaft of the rotary wheel 41, and each storage rack 6 extends along a length direction of the rotary shaft of the rotary wheel 41. Several gasket bodies 45 are slidably mounted between two storage racks 6, and sides of the storage racks 6 close to each other are each configured with a holding groove 61 adapted to the gasket body 45. The holding groove 61 has an arc shape, and an inner arc surface of the holding groove 61 is configured to abut against the gasket bodies 45. Several gasket bodies 45 are arranged along the length direction of the rotary shaft of the rotary wheel 41 and are sleeved over the rotary shaft of the rotary wheel 41. The storage rack 6 is provided with a limiting assembly 7 for limiting the gasket body 45.

(18) The limiting assembly 7 includes a first stop block 71 and a second stop block 72, and the storage rack 6 is configured with a first sliding groove 62 and a second sliding groove 63. The first stop block 71 is slidably mounted on the storage rack 6 along a length direction of the storage rack 6 through the first sliding groove 62, and the second stop block 72 is slidably mounted at an end of the storage rack 6 away from the stander 4 along a direction perpendicular to the length direction of the storage rack 6 through the second sliding groove 63. The end of the second stop block 72 facing a radially inner side of the storage rack 6 is provided with an elastic member 73 which in the present embodiment is a spring. One end of the elastic member 73 is sleeved over the second stop block 72, while the other end thereof is fixed at the groove bottom of the second sliding groove 63. The second stop block 72 is provided with a first guide surface at each of the two sides thereof along the length direction of the storage rack 6. Each gasket body 45 is mounted between the first stop block 71 and the second stop block 72. A fifth driver 74 is provided on a side of the first stop block 71 away from the second stop block 72 for driving the first stop block 71 to slide. In the present embodiment, the fifth driver 74 is a cylinder and is fixedly mounted on the storage rack 6, and the piston rod thereof is connected to the first stop block 71.

(19) Referring to FIG. 4, a second guide surface 411 is configured on an outer periphery of the rotary wheel 41 along a circumferential direction thereof, and the second guide surface 411 directly faces the storage racks 6 and abuts against the gasket body 45 on a side of the second stop block 72 away from the first stop block 71. The rotary wheel 41 is configured with a slot for handling 412 along the circumferential direction thereof at a side of the second guide surface 411 away from the stander 4.

(20) Before the winding operation of the gasket body 45 is started, a plurality of gasket bodies 45 are sleeved over the rotary wheel 41 and clamped between the two storage racks 6, and at this time, the fifth driver 74 drives the first stop block 71 to move toward the stander 4 until a predetermined number of gasket bodies 45 are filled between the two storage racks 6.

(21) When the winding operation of the gasket body 45 is started, the fifth driver 74 is activated to drive the first stop block 71 to slide in the storage racks 6 until abutting against the innermost gasket body 45, so as to push the gasket bodies 45 to move until the outermost gasket body 45 abuts against the second stop block 72. After being pushed, the outermost gasket body 45 pushes the second stop block 72 to slide into the second sliding groove 63 via the first guide surface, and thus the outermost gasket body 45 may slide onto the second guide surface 411 on the rotary wheel 41 after passing the position where the second stop block 72 is located, and at this time, the worker activates the rotary wheel 41, so that the wheel body moves in a direction away from the stander 4, thereby enabling the outermost gasket body 45 to slide in a direction away from the stander 4 via the second guide surface 411 after abutting against the second guide surface 411. After the gasket body 45 is moved to the slot for handling 412, the gasket body 45 is sleeved on the rotary wheel 41, thereby enabling the worker to perform a winding process on the gasket body 45, which reduces the labor cost required for the worker to take a new gasket body 45 and improves the automation of the winding machine for the spiral wound gasket.

(22) Referring to FIG. 3, the stander 4 is provided with a mounting base between the graphite tray 42 and the conveyor, and a photoelectric sensor, a laser transmitter and an alarming device are provided on the mounting base. When the graphite strip 46 is transferred between the photosensor and the laser transmitter, the laser light is blocked, so that the photosensor may not sense the laser light, and no alarm is sent out. When there is no graphite strip 46 between the photosensor and the laser transmitter, the photosensor senses the laser light from the laser transmitter and triggers the alarming device to generate an alarm.

(23) The above-mentioned preferred embodiments of the present application do not limit the protection scope of the present application, and therefore: all equivalent variations in the structure, shape, and principles of the present application are intended to be within the scope of the present application.
