[0023] Please refer to Figure 1-7, the utility model provides a technical solution: a rewinding quick clamping mechanism, including an operating table 1. On one side surface of the operating table 1, a motor 2 is connected. The output end of the motor 2 is connected with a connecting block 3. On one side surface of the connecting block 3, a snap disc 4 is connected. On one side surface of the snap disc 4, a clamping assembly 5 is snap-connected. On one side surface of the clamping assembly 5, a winding paper roller 6 is connected. On one side surface of the winding paper roller 6, a limiting plate 7 is connected. There are two limiting plates 7 which are symmetrically distributed. The winding paper roller 6 is used for winding the self-adhesive paper, and the limiting plate 7 limits the two ends of the self-adhesive paper. Inside the snap disc 4, a rotating rod 8 is movably connected. On one side surface of the rotating rod 8, a movable plate 9 is movably connected. On one side surface of the movable plate 9, a clamping block 10 is connected. On one side surface of the movable plate 9, a pressing block 11 is connected. The movable plate 9 is movably connected inside the snap disc 4. There are two movable plates 9 which are symmetrically distributed inside the snap disc 4. The middle of the movable plate 9 is fixed by the rotating rod 8, but the movable plate 9 can rotate outside the rotating rod 8. When pressing the two pressing blocks 11 inward, the other side of the movable plate 9 can expand in the opposite direction.

[0024] There are two snap discs 4 which are symmetrically distributed, and two clamping assemblies 5 which are symmetrically distributed. On one side surface of the inside of the snap disc 4, a soft pad 14 is connected. One side of the soft pad 14 facilitates the snapping of the snap block 15, and the other side facilitates the inward pressing of the movable plate 9. On one side surface of the inside of the snap disc 4, a spring 12 is connected. One end of the spring 12 is fixedly connected with one side surface of the movable plate 9. The spring 12 has elastic potential energy and can provide a force for inward pressing on the movable plate 9. At both ends of the spring 12, there are bottom rings 13. One end of the bottom ring 13 is connected to one side surface of the inside of the snap disc 4, and the other end of the bottom ring 13 is connected to one side surface of the movable plate 9. The bottom ring 13 is used to protect both ends of the spring 12 to prevent the spring 12 from being damaged. There are four springs 12 which are distributed in a linear array.

[0025] On one side surface of the operating table 1, a rotating bearing 23 is connected. On one side surface of the rotating bearing 23, a connecting block 3 is connected. The outer ring of the rotating bearing 23 is connected to one side surface of the operating table 1, and the inner ring of the rotating bearing 23 is connected to one side surface of the connecting block 3. On one side surface of the connecting block 3, a snap disc 4 is connected. On one side surface of the snap disc 4, a clamping assembly 5 is connected. One side surface of the clamping assembly 5 is connected to the other end of the winding paper roller 6. The clamping assembly 5 clamps and fixes the winding paper roller 6 at both ends.

[0026] The clamping assembly 5 includes a snap block 15, a clamping rod 17 and an opening / closing plate 20. A clamping groove 16 is formed on one side surface of the snap block 15. The clamping groove 16 is adapted to the clamping block 10. The clamping block 10 is snapped inside the clamping groove 16 for clamping and fixing the clamping assembly 5. A sliding groove 18 is formed on one side surface of the clamping rod 17. The sliding groove 18 is adapted to one end of the rotating rod 8. The sliding groove 18 is used for placing the rotating rod 8 to prevent the rotating rod 8 from being restricted and unable to rotate. An opening / closing plate 20 is movably connected to one side surface of the clamping rod 17. A clamping thorn 21 is connected to one side surface of the opening / closing plate 20. The opening / closing plate 20 can open and close on one side of the clamping rod 17, mainly for fixedly clamping the winding paper roll 6. A clamping groove 19 is formed on one side surface of the clamping rod 17.

[0027] Four opening / closing plates 20 are arranged in a circumferential array. Four clamping thorns 21 are arranged in a circumferential array. The clamping thorns 21 are adapted to the opening / closing plates 20. The clamping thorns 21 and the opening / closing plates 20 cooperate with each other to more effectively clamp the winding paper roll 6. A rotating ring 22 is movably connected to one side surface of the opening / closing plate 20. The rotating ring 22 rotates towards one side of the opening / closing plate 20 through threads to tighten the closing of the opening / closing plate 20.

[0028] A sliding rod 26 is connected to one side surface of the operating table 1. A threaded rod 24 is movably connected to one side surface of the operating table 1 through a rotating bearing 23. A top plate 25 is connected to one side surface of the threaded rod 24. The sliding rod 26 is connected to one side surface of the top plate 25. The top plate 25 is used to limit the tops of the threaded rod 24 and the sliding rod 26. The top plate 25 also facilitates the rotation of the threaded rod 24. A lifting plate 27 is movably connected to the outside of the threaded rod 24. The lifting plate 27 can rotate on the outside of the threaded rod 24. The lifting plate 27 is movably connected to the outside of the sliding rod 26. The lifting plate 27 can slide on the outside of the sliding rod 26. A counterweight plate 28 is connected to one side surface of the lifting plate 27. The counterweight plate 28 is used to apply a certain pressure to the pressing pad 29 and below, facilitating the winding of the self-adhesive paper and effectively preventing the self-adhesive paper from being greatly loose and having gaps during the winding process. A pressing pad 29 is connected to one side surface of the counterweight plate 28. One side of the pressing pad 29 contacts the self-adhesive paper being wound and applies pressure to the self-adhesive paper being wound.

[0029] The pressing pad 29 is arranged directly above the winding paper roll 6. A loading rack 30 is connected to one side surface of the operating table 1. The processed self-adhesive paper passes through the upper end of the loading rack 30 and is then wound on the winding paper roll 6. A placing groove 31 is formed on one side surface of the operating table 1. The placing groove 31 is used for placing the second installed winding paper roll 6.

[0030] Working principle: Before the utility model is used, rotate the rotating ring 22 and move it backward, so that the opening and closing plate 20 can be opened on one side by using the hinge at the rear end. One end of the winding paper roller 6 is snap-connected to one side of the clamping rod 17, the opening and closing plate 20 is closed, and the rotating ring 22 is rotated toward the opening and closing plate 20 by threads, so as to fasten the closing of the opening and closing plate 20. Then, by using the cooperation of the clamping thorns 21 and the clamping grooves 19, one end of the winding paper roller 6 is effectively fixed on one side of the clamping assembly 5. The other end of the winding paper roller 6 is fixed with a clamping assembly 5 on one side of the winding paper roller 6 by the same method as above. The snap block 15 at the rear end of the clamping rod 17 is snapped into the snap disk 4. During the movement of the snap, the snap block 15 presses the clamping blocks 10 on both sides inside the snap disk 4, so that the clamping blocks 10 and the movable plate 9 move outward. When one end of the snap block 15 is snapped to the bottom end inside the snap disk 4, the spring 12 has elastic potential energy and acts on the movable plate 9, and at the same time has a force on the clamping block 10 on one side of the movable plate 9. This force drives the movable plate 9 to rotate, so that the clamping block 10 is snap-fixed inside the card slot 16 at the side end of the snap block 15. Due to the shape characteristics of the clamping block 10 and the card slot 16, the snap block 15 can be effectively snap-fixed inside the snap disk 4.

[0031] It should be noted that there are many rollers provided in the feeding mechanism at the front end. Since these are prior arts, the feeding mechanism at the front end is not described. This patent only protects the quick clamping mechanism of the rollers. Therefore, the technical core lies in how to quickly clamp the rollers and replace new rollers.

[0032] When the clamping components 5 at both ends of the winding paper roller 6 are fixedly buckled on one side of the buckle plate 4, one side of the self-adhesive paper is closely adhered to the outer side of the winding paper roller 6. The output end of the motor 2 is connected to the connecting block 3, and the connecting block 3 on the other side is connected to the rotating bearing 23. When the motor 2 starts, it drives the overall rotation and winding. During the winding process, the pressing pad 29 is subjected to the acting force of the counterweight plate 28 above, so that the lower end of the pressing pad 29 is in mutual contact with the self-adhesive paper on the winding paper roller 6, reducing the generation of gaps and bubbles during the winding of the self-adhesive paper. Since one end of the operating table 1 is connected to the threaded rod 24 through the rotating bearing 23, the lifting plate 27 is movably connected to the outer side of the threaded rod 24, and the lifting plate 27 is connected to the counterweight plate 28. As the diameter size of the winding continuously increases, the positions of the counterweight plate 28 and the pressing pad 29 will also continuously move upward, and the overall can ensure the winding efficiency and quality. When the winding reaches a certain diameter size, the motor 2 is stopped from rotating, and the self-adhesive paper is cut off. By pressing the extrusion block 11, the rotating rod 8 serves as the fulcrum of the pressing extrusion block 11. Under the fulcrum action of the pressing extrusion block 11, the pressing force is greater than the force generated by the elastic potential energy of the spring 12, so that the other side of the movable plate 9 can expand in the opposite direction, realizing the lever technical principle. A gap appears inside the buckle plate 4, and the buckle block 15 can be taken out from inside the buckle plate 4, so as to realize the overall removal of the winding paper roller 6 and the clamping components 5. The second installed winding paper roller 6 placed in the placement groove 31 is buckled on one side of the buckle plate 4 according to the above method. The overall effectively realizes the quick replacement of the winding device, can effectively be applied to the rapid production of self-adhesive paper, avoids the waste of time and the accumulation waste of self-adhesive paper during the winding process, saves resources, separates the removed winding paper roller 6 and the clamping components 5, and processes and uses the wound self-adhesive paper and the winding paper roller 6 in the next step. The removed clamping components 5 clamp the new winding paper roller 6 and place it inside the placement groove 31 for the next replacement. The overall facilitates the rapid production and winding of self-adhesive paper and improves the practicability.
