[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] refer to Figures 1-5The embodiments of this utility model will now be described. A polyimide film production trimming mechanism includes a base plate 1. Two first support seats 2 and a fixing frame 4 are fixedly connected sequentially from back to front on the upper end of the base plate 1. A first guide roller 3 is rotatably connected between the two first support seats 2. A second guide roller 5 is rotatably connected inside the fixing frame 4, located above the first guide roller 3. Two cutting blades 6 are connected inside the fixing frame 4 via a first adjusting assembly 7, located directly above the second guide roller 5. Two support plates 9 are connected to the upper end of the base plate 1 via a second adjusting assembly 8, located at the front end of the fixing frame 4. A first support roller 10 is rotatably connected inside each of the two support plates 9. A second clamping plate 14 is slidably connected to the circumferential surface of each of the two first support rollers 10. A third adjusting assembly 11 is connected to the ends of the two second clamping plates 14 that are far apart from each other, and the third adjusting assembly 11 is used to adjust the position of the second clamping plates 14. Each of the two first support rollers 10 has a slot 18 and an insertion hole 19 inside, and the slot 18 and the insertion hole 19 are interconnected. Each of the rollers 10 has a second support roller 12 connected to its closest end. A first clamping disc 13 is fixedly connected to the circumferential surface of each of the two second support rollers 12, and the first clamping disc 13 cooperates with the second clamping disc 14 to clamp the scrap material roll. A connecting post 23 is fixedly connected to the far end of each of the two second support rollers 12. A threaded shaft 15 is fixedly connected to the far end of each of the two connecting posts 23. The threaded shaft 15 is connected to the first support roller 10 through a insertion hole 19, and the connecting post 23 is connected to the first support roller 10 through a slot 18. The support roller 10 is connected, and the circumferential surface of the threaded shaft 15 is threaded with a nut 24, which cooperates with the threaded shaft 15 and the first support roller 10 to fix the second support roller 12. A support frame 17 is fixedly connected to the left end of the left support plate 9, and a first motor 21 is fixedly connected to the top of the support frame 17. A drive wheel 22 is fixedly connected to the output shaft end of the first motor 21. A driven wheel 16 is fixedly connected to the circumferential surface of the first support roller 10 on the left side. The drive wheel 22 and the driven wheel 16 are connected by a synchronous belt 20.During operation, first unscrew nut 24. After nut 24 disengages from the first support roller 10, remove the second support roller 12 from one side of the first support roller 10. Then, place the scrap material roll onto the surface of the first support roller 10, and reinstall the second support roller 12. At this time, the scrap material roll is located between the first clamping plate 13 and the second clamping plate 14. Next, control the third adjusting component 11 to move the second clamping plate 14 towards the first clamping plate 13, so that the scrap material roll is firmly clamped between the first clamping plate 13 and the second clamping plate 14. Then, place the roll of polyimide film (hereinafter referred to as the film roll) corresponding to the two first clamping plates. Between the holding discs 13, one side of the film roll is fitted onto the surface of the second support roller 12. Then, the second adjusting component 8 is controlled to work, driving the two support plates 9 to move closer to each other until the two first clamping discs 13 tightly clamp the film roll. Then, the first motor 21 is controlled to work. With the cooperation of the driving wheel 22, the driven wheel 16 and the synchronous belt 20, the first support roller 10 is driven to rotate, thereby driving the second support roller 12 to rotate, and then driving the film roll and the scrap roll to rotate simultaneously. This allows the trimmed polyimide film and the trimmed polyimide film scraps to be wound up at the same time, preventing the polyimide film scraps from scattering on the ground.

[0024] Compared with the prior art, this utility model can simultaneously wind up the polyimide film scraps after the edges have been trimmed, thus preventing the polyimide film scraps from scattering and affecting the working environment, and also facilitating the recycling of the polyimide film scraps.

A first bidirectional threaded rod 704 is connected to a handle 706 fixedly connected to its left end. The handle 706 is located on the left side of the fixed frame 4. The circumferential surface of the first bidirectional threaded rod 704 is threaded with two sliding seats 705 with opposite internal thread directions. Both sliding seats 705 are slidably connected to the movable frame 703. Two cutting blades 6 are respectively fixedly installed at the bottom ends of the two sliding seats 705. The left end face of the fixed frame 4 has an elongated hole through which the first bidirectional threaded rod 704 passes, and the handle 706 is located on the left side of the elongated hole. When the electric telescopic rod 701 is working, it can drive the movable frame 703 to move up and down, thereby driving the two cutting blades 6 to move up and down, so that the cutting blades 6 can move to different heights as needed to cut polyimide films of different thicknesses. When the handle 706 is rotated, it drives the first bidirectional threaded rod 704 to rotate. At this time, the two sliding seats 705 can drive the two cutting blades 6 to move closer or further apart, so as to perform edge trimming of different widths on the polyimide film.

When the second motor 801 operates, it drives the second bidirectional threaded rod 803 to rotate. At this time, the two support plates 9 can move closer or further apart, thereby driving the two first clamping discs 13 to move, so as to clamp and fix film rolls of different lengths through the two first clamping discs 13.

[0027] In another embodiment of this utility model, see Figure 1 and Figure 2The third adjustment component 11 includes a connecting seat 1101, a connecting plate 1102, a third threaded rod 1103, and a third guide rod 1104.

The third threaded rod 1103 passes through the support plate 9 and is threadedly connected to it. The third guide rod 1104 is fixedly connected to the side of the connecting plate 1102 near the support plate 9. The third guide rod 1104 passes through the support plate 9 and is slidably connected to it. During operation, rotating the third threaded rod 1103, in cooperation with the connecting plate 1102, causes the connecting seat 1101 and the second clamping plate 14 to move closer to or further away from the first clamping plate 13, so that the first clamping plate 13 and the second clamping plate 14 can clamp and fix scrap material rolls of different lengths through their cooperation.

[0029] In another embodiment of this utility model, please refer to Figure 4 and Figure 5 Both the slot 18 and the connecting post 23 have hexagonal end faces. During operation, with the cooperation of the slot 18 and the connecting post 23, the rotation of the first support roller 10 drives the second support roller 12 to rotate, thereby enabling the film roll located between the two first clamping discs 13 to smoothly perform rotation and winding operations.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
