The clamping plate 4 is arc-shaped, and a self-locking component is provided on the top frame 2. A slide groove 27 is provided on the top of the top frame 2, and the slide block 20 is limited by the slide groove 27. The groove wall of the slide groove 27 contacts and is slidably connected to the slide block 20, so that the slide block 20 slides more stably in the slide groove 27. The top of the slide block 20 is fixedly connected with a movable plate 21, and the movable plate 21 follows the slide block 20 and approaches each other until the rollers 23 on the adjacent side of the movable plate 21 are against the two sides of the coil, which helps to limit the position of the coil. There are two movable plates 21, and a rectangular groove 22 is provided on the adjacent side of the two movable plates 21. The groove wall of the rectangular groove 22 is fixedly connected with the roller The wheel 23 has two rollers 23. The setting of the rollers 23 can reduce the friction of the contact between the two sides of the coil and reduce the possibility of burrs on both sides of the coil. The front of the slider 20 is hinged with a connecting rod 19 through a pin. The two ends of the two connecting rods 19 rotate around the hinge. The bottom of the connecting rod 19 is hinged with a connecting block 18. The connecting block 18 plays a hinged role on one end of the two connecting rods 19. The bottom of the connecting block 18 is fixedly connected to a tooth plate 11. One side of the tooth plate 11 is fixedly connected to a pedal 10. By stepping on the pedal 10, the pedal 10 drives the tooth plate 11 to move downward. The two sides of the tooth plate 11 are respectively fixedly connected to a strip block 16. The other side of the strip block 16 is fixedly connected to The number of the limit block 17, the strip block 16, and the limit block 17 are respectively two, and the inner walls on both sides of the top frame 2 are respectively provided with a strip groove 24, which plays a limiting role on the limit block 17. The limit block 17 contacts and slides with the groove wall of the strip groove 24, so that the limit block 17 slides more stably in the strip groove 24. The groove wall of the strip groove 24 is fixedly connected with a spring 25, and the other end of the spring 25 is fixedly connected to the bottom of the limit block 17. The number of the strip grooves 24 is two, and the number of the springs 25 is two. The pawl 15 is disengaged from the ratchet 14, and the two movable plates 21 are returned to their positions by the longitudinal elastic potential energy of the spring 25.

[0025] Reference Figure 1 、 Figure 3The self-locking assembly includes a rotating rod 13, the two ends of which are rotatably connected to the inner walls of the two sides of the top frame 2 through bearings. A driven gear 12 is fixed on the surface of the rotating rod 13, and the toothed plate 11 is engaged with the driven gear 12. Through the engagement of the toothed plate 11 and the driven gear 12, the toothed plate 11 drives the driven gear 12 to rotate, and the driven gear 12 drives the rotating rod 13 to rotate, so that the rotating rod 13 drives the ratchet 14 to rotate. A pawl 15 is fixed on the surface of the rotating rod 13, and the inner side of the top frame 2 is rotatably connected to the pawl 15 through a torsion spring. The pawl 15 abuts against the adjacent side of the ratchet 14. When the ratchet 14 rotates in a specific direction, the pawl 15 is lifted by the action of the teeth of the ratchet 14 and does not hinder the rotation of the ratchet 14. When the ratchet 14 tries to rotate in the opposite direction, the pawl 15 will be stuck in the tooth groove of the ratchet 14, preventing the reverse movement of the ratchet 14. Due to the special shape design of the pawl 15 and the teeth of the ratchet 14, once the pawl 15 is stuck in the tooth groove of the ratchet 14, a large force needs to be overcome to disengage the pawl 15 from the tooth groove, thereby realizing a self-locking function. This self-locking state can keep the ratchet 14 stationary in a specific position and prevent it from rotating in an unwanted direction.

[0026] Reference Figure 1 The top of the top frame 2 is fixedly connected with a top plate 7, and the top plate 7 is in a "U" shape. A threaded hole is opened on the top of the top plate 7, and the threaded hole is used to cooperate with the threaded rod 8. The threaded hole is connected with a threaded rod 8, and the threaded rod 8 rotates in the threaded hole, which can make the threaded rod 8 move up and down in the threaded hole. The top of the threaded rod 8 is fixedly connected with a knob, which is convenient for the operator to rotate the threaded rod 8. The bottom end of the threaded rod 8 is rotatably connected with a positioning roller 9 through a bearing. The positioning roller 9 can follow the threaded rod 8 to move up and down. Both sides of the positioning roller 9 are in contact with the inner side of the top plate 7 and are slidably connected. The positioning roller 9 is pressed on the surface of the coil, so that the roller 23 rolls on the surface of the coil, so that the reverse side of the coil can better fit on the surface of the connecting plate, thereby improving the stability of the coil during feeding.

[0027] Working principle: put the coil on the rotating roller 5, start the electric cylinder 6, use the telescopic end of the electric cylinder 6 to drive the clamping plate 4 to push, use the surface of the clamping plate 4 to clamp the surface of the coil inner cavity, start the motor, so that the output shaft of the motor drives the rotating roller 5 to rotate, and the rotating roller 5 rotates to drive the coil to start unwinding, which can clamp different coils; turn the knob to make the knob drive the threaded rod 8 to rotate, and the threaded rod 8 moves downward in the threaded hole, and the positioning roller 9 follows the threaded rod 8 to move downward until the positioning roller 9 is fixed. The positioning roller 9 is pressed on the surface of the coil, so that the roller 23 rolls on the surface of the coil, so that the back of the coil can better fit the surface of the connecting plate; by stepping on the pedal 10, the pedal 10 drives the toothed plate 11 to move downward, and the two ends of the two connecting rods 19 rotate around the hinge respectively, so that the top of the connecting rod 19 pulls the slider 20 to slide in the slide groove 27, and the moving plate 21 follows the slider 20 to approach each other, and the moving plates 21 are moved closer to each other until the rollers 23 on the adjacent side of the moving plate 21 are against the two sides of the coil. It helps to define the position of the coil, and at the same time, the setting of the roller 23 can reduce the friction of the contact between the two sides of the coil; through the engagement of the tooth plate 11 and the driven gear 12, the tooth plate 11 drives the driven gear 12 to rotate, and the driven gear 12 drives the rotating rod 13 to rotate, so that the rotating rod 13 drives the ratchet 14 to rotate. When the ratchet 14 rotates in a specific direction, the pawl 15 is lifted by the action of the teeth of the ratchet 14 and does not hinder the rotation of the ratchet 14. When the ratchet 14 tries to rotate in the opposite direction, the pawl 15 will be stuck in the ratchet 14. In the tooth groove, the reverse movement of the ratchet 14 is prevented. Due to the special shape design of the pawl 15 and the teeth of the ratchet 14, once the pawl 15 is stuck in the tooth groove of the ratchet 14, a large force needs to be overcome to disengage the pawl 15 from the tooth groove, thereby realizing a self-locking function. This self-locking state can keep the ratchet 14 stationary in a specific position and prevent it from rotating in an unnecessary direction. When the movable plate 21 needs to be returned, it is only necessary to disengage the pawl 15 from the ratchet 14 and return the two movable plates 21 to their original positions through the longitudinal elastic potential energy of the spring 25.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
