The chain guides 301 and material-returning profiles 302 are arranged crosswise, and magnets 303 are distributed on one group of the material-returning profiles 302 .

[0036] In this embodiment, preferably, several groups of the pin assemblies 40 are installed on the bottom of the feed support plate 10 through a profile, and fixed pins 408 are also provided on both sides of the top of the cylinder seat 401, and the bottom end of the movable pin 404 is integrally provided with a first round table 4041, and the bottom end of the first round table 4041 is integrally provided with a second round table 4042, and the bottom end of the second round table 4042 is set as a cone structure; a conical hole 4031 matching the second round table 4042 is provided in the pin base 403, and locking grooves 4032 matching the lock buckle 405 are integrally provided on both sides.

[0038] In this embodiment, preferably, the feed support plate 10 is provided with through holes 101 for the movable pins 404 and the fixed pins 408 to pass through.

[0039] In this embodiment, preferably, the cutter assembly 50 is movably arranged between the feed support plate 10 and the servo lower conveyor belt 20 through a slide rail slider, the cutter assembly 50 is connected to a cutter motor 60 that drives it to move through a synchronous belt drive, the cutter assembly 50 includes a sliding seat 501, a cutter base 502 and a cutter 503, the cutter base 502 is movably arranged above the sliding seat 501 through a guide rod and a linear bearing, a spring 504 is provided on the guide rod between the cutter base 502 and the sliding seat 501, and one side of the cutter base 502 is also provided with The cutter cylinder 505 drives it to descend, and the cutter 503 is fixed on the top of the cutter base 502. When a bed net is rolled up, the cutter cylinder 505 releases the cutter base 502, and the cutter base 502 rises under the elastic force of the spring 504, so that the cutter 503 rises and contacts the coiled material, and then moves along the width direction of the material dragging support plate 10 under the drive of the cutter motor 60 to cut the coiled material; after cutting, the cutter cylinder 505 pulls the cutter base 502 and the cutter 503 down and away from the coiled material, and then the cutter motor 60 drives the cutter base 502 and the cutter 503 to reset.

[0040] In this embodiment, preferably, the servo lower conveyor belt 20 is configured to be an arc-shaped structure that better fits the bottom of the winding shaft 30, and the bottom of the servo lower conveyor belt 20 is provided with a first servo module 201 for driving it to rise and fall; the bottom of the feed pallet 10 is provided with a second servo module 102 for driving it to move, and through the cooperation of the first servo module 201 and the second servo module 102, the discharge end of the feed pallet 10 can be fitted with the bottom of the winding shaft 30, so that the movable pin 404 can be smoothly inserted into the socket 3031 of the magnet 303.

[0041] The specific working principle of the present invention is as follows: initially, the end of the coil needs to be manually pulled to the discharge end of the feed support plate 10 and fixed, and then the lifting cylinder 402 drives the cylinder seat 401 to rise, so that the movable pin 404 and the fixed pin 408 rise and pass through the coil, and then the first servo module 201 and the second servo module 102 drive the feed support plate 10 to rise and move, so that the discharge end of the feed support plate 10 is close to the bottom of the winding shaft 30, and under the control of the numerical control system, the winding shaft 30 starts to rotate slowly, so that the magnet 303 on the unloaded profile 302 The first servo module 201 drives the feed support plate 10 to rise by aligning the movable pin 404, so that the movable pin 404 is inserted into the first insertion hole 3031 of the magnet 303, and the fixed pin 408 is inserted into the second insertion hole 3021 of the unreeling profile 302, and the coil is nailed to the reeling shaft 30; the lock 405 is driven to open by the lock cylinder 407, and then the lifting cylinder 402 drives the cylinder seat 401 to descend, so that the fixed pin 408 descends and leaves the second insertion hole 3021, and the movable pin 404 remains in the magnet 30 under the action of the magnetic force. 3, then the first servo module 201 and the second servo module 102 drive the feeding support plate 10 to drop away from the bottom of the winding shaft 30, and the coiled material is continued to be pinned to the winding shaft 30 by the movable pin 404, and the winding shaft 30 is rotated to make the coiled material wound on the winding shaft 30. When rotating, since the bottom end of the second truncated cone 4042 of the movable pin 404 is a cone structure, it can penetrate the coiled material, so the movable pin 404 will not be wrapped in the coiled material. After the winding shaft 30 rotates several times, the coiled material no longer needs the movable pin 404. When the movable pin 404 can be wound along with the rotation of the winding shaft 30, the first servo module 201 and the second servo module 102 drive the feeding support plate 10 to rise close to the bottom of the winding shaft 30, and the lifting cylinder 402 drives the cylinder seat 401 to rise, so that the bottom end of the second truncated cone 4042 of the movable pin 404 is inserted into the conical hole 4031 of the pin base 403, and then locked by the lock 405, so that the movable pin 404 can be transferred from the winding shaft 30 back to the pin base 403. After completing the above actions, the bed net can start feeding and enter between the winding shaft 30 and the coil for winding.

[0042] After the first roll is completed, the lifting cylinder 402 drives the cylinder seat 401 to rise, so that the movable pin 404 and the fixed pin 408 rise and pass through the coil (the coil is in a tensioned state at this time, so the movable pin 404 and the fixed pin 408 can smoothly penetrate the coil), and then the cutter cylinder 505 releases the cutter base 502, and the cutter base 502 rises under the elastic force of the spring 504, so that the cutter 503 rises and contacts the coil, and then moves along the width direction of the drag material support plate 10 under the drive of the cutter motor 60 to cut the coil; after cutting, the cutter cylinder 505 pulls the cutter base 502 and the cutter 503 down and away from the coil, and then the cutter motor 60 drives the cutter base 502 and the cutter 503 to reset. Then the first servo module 201 and the second servo module 102 drive the feed support plate 10 to rise and move, repeat the above actions, and nail the coil on the winding shaft 30.

[0043] Therefore, except for the initial need to manually pull the end of the coil to the discharge end of the feed pallet 10 and fix it, each subsequent winding can be nailed to the winding shaft 30 by the movable pin 404 without the need for manual operation, thereby achieving a continuous feeding effect.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technicians in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
