DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4The shown device is an ASA multi-layer film winding device for plastic processing, comprising a support base 1, which is a U-shaped structure. A cylinder 2 is provided on the support base 1, and a clamp 21 is provided at the telescopic end of the cylinder 2, which is a U-shaped structure, and its purpose is to quickly dock one end of the winding mechanism (the winding mechanism is rotatably connected to the support base 1); a support guide roller 11 and a scraping device 14 are rotatably connected to the support base 1 (on the side of the winding mechanism), and the film is scraped and flattened by the scraping device 14 to avoid quality problems of the film when winding.

[0023] As an implementation method in this embodiment, two groups of top rings 12 are slidably connected to the support guide roller 11, and the opposite sides of the two groups of top rings 12 are connected to the support base 1 through connecting springs 13. Under the action of the connecting springs 13, the film passing through the support guide roller 11 is centered.

[0024] As an implementation method in this embodiment, the winding mechanism: the inner shaft 4 is provided with an inner cavity 41 connected to the outside, and a lock head 3 is fixed at both ends of the inner cavity 41 by bolts, the lock head 3 is cross-shaped, and a hole communicating with the left and right is provided at the center of the lock head 3, a sliding hole 42 communicating with the outside is provided on the inner wall of the inner cavity 41, and the sliding hole 42 is provided with four groups, and each group of sliding holes 42 is provided with positioning holes 43 communicating with the outside on the left and right inner walls; a slider 6 is slidably connected in the sliding hole 42, and a reset groove 61 is provided on the outer wall of the slider 6, a positioning block 15 is slidably connected in the positioning hole 43, the inner end of the positioning block 15 is inserted into the reset groove 61, and in order to realize the reset function of the slider 6 after it is extended, A return spring 7 is installed in the positioning groove 61, and the return spring 7 is pressed between the return groove 61 and the positioning block 15 (in order to prevent the positioning block 15 from falling off during use, the diameter of the lock head 3 covers part of the positioning hole 43). An air bag 5 that can push the slider 6 outward is provided inside the inner cavity 41. Air nozzles 51 are provided at both ends of the air bag 5, and the air nozzles 51 pass through the holes of the lock head 3 to connect to the outside world. One group is used for inflation and the other group is used for deflation. An arc-shaped movable plate 8 is fixed to the outward end surface of the slider 6 by bolts. Therefore, through the above technical solution, after the air bag 5 is inflated, the four groups of sliders 6 are pushed outward to increase the spacing between the four groups of movable plates 8. After completing the winding task, the air bag 5 is deflated to remove the film.

[0025] The return spring 7 in the above structural description is used when the airbag 5 is deflated. The return spring 7 uses the positioning block 15 as a support point to push the slider 6 inward.

[0026] As an implementation method in this embodiment, when the above task is completed, the telescopic end of the cylinder 2 is retracted to release the contact with the lock head 3 so that the rolled-up film can be removed from it.

[0027] As an implementation method in this embodiment, the lock head 3 rotating on the support base 1 is connected to the winding motor through a gear group. The driven gear 9 in the gear group is coaxially arranged with the lock head 3. The driving gear 10 is rotatably connected to the support base 1, and the driving gear 10 and the driven gear 9 are meshed with each other. When starting, the winding motor drives the driving gear 10 to rotate, thereby driving the driven gear 9 to rotate.

[0028] The working principle of the utility model is as follows: by using the air delivery device, a group of air nozzles 51 are connected to deliver the gas into the airbag 5, the volume of the airbag 5 gradually expands, and while filling the inner cavity 41, it presses against the inner end surface of the slider 6, so that the slider 6 slides in the slide hole 42, and the slider 6 sliding outward pushes the movable plate 8 outward, thereby expanding the distance between the four groups of movable plates 8. After completing the above operations, the winding motor is started, and the winding motor drives the driven gear 9 meshing with it to rotate through the driving gear 10, and then the driven gear 9 drives the lock head 3 to rotate on the support base 1, and the other group of lock heads 3 rotates on the clamp 21. In the process of winding the film, the film is centered by the top ring 12 on the support guide roller 11. The top ring 12 is autonomously adapted to films of different specifications under the action of the connecting spring 13, and the film is scraped and leveled by the scraping device 14 to avoid quality problems.

[0029] After completing the above-mentioned winding task, the gas in the airbag 5 is discharged by using another set of air nozzles 51, so that under the action of the reset spring 7, the reset spring 7 uses the positioning block 15 as a support point to push the reset groove 61 in the opposite direction, so that the reset groove 61 completes the reset and retraction of the movable plate 8 when pushing back. When the reset spring 7 needs to be maintained, the lock head 3 is first removed, and then the positioning block 15 in the positioning hole 43 is taken out to release the limit with the slider 6, and then the slider 6 is taken out from the slide hole 42, and then the reset spring 7 is taken out.
