[0013] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0014] First, when trimming the polyimide film in the present invention, first remove the rotating cover on the releasing rod by rotating it. At this time, the whole roll of polyimide film needs to be sleeved on the releasing rod, and then rotate the rotating cover onto the releasing rod. In the same way, when sleeving the winding roller on the winding rod, then drive the driving shaft at the output end of the driving motor to rotate on the corresponding driving frame by running the driving motor. The rotation of the driving shaft drives the driving helical gear to rotate, and the rotation of the driving helical gear drives the driven helical gear to rotate, thereby driving the releasing rod to rotate on the fixed frame. The rotation of the releasing rod drives the whole roll of polyimide film on the releasing rod to rotate, so as to place the leading end of the whole roll of polyimide film out a relative length and sleeve its leading end on the rotating roller. At this time, the two sides of the product are trimmed by the corresponding trimming equipment. When the trimming length is sufficient to sleeve the leading end on the winding rod, the preliminary operation of the whole roll of polyimide film is completed. The rotation of the driving shaft synchronously drives the rotating helical gear to rotate, and the rotation of the rotating helical gear drives the adjusting helical gear to rotate, thereby driving the winding rod to rotate to wind the trimmed product. At this time, the releasing rod and the winding rod are in a state of rotating in opposite directions and synchronously rotating, so that the polyimide film released by the releasing rod and the polyimide film wound by the winding rod are of the same length. Therefore, during the operation of the polyimide film, it is always in a precise trimming operation state and will not loosen, wrinkle or break due to being too long or too short, thereby improving the processing quality of the product.

[0015] Second, during the trimming operation of the polyimide film in the present invention, due to the different thicknesses and types of the whole roll of polyimide film, at this time, by adjusting the operation of the hydraulic cylinder to drive the adjusting plate on the output end of the adjusting hydraulic cylinder to move upward or downward, thereby driving the adjusting frame, adjusting column, adjusting bevel gear, rotating bevel gear and winding rod on the adjusting plate to move upward or downward, so as to adjust the distance between the winding rod and the unwinding rod, and achieve applicability to the whole roll of polyimide film with different thicknesses and different types.

[0016] Third, when the head end of the whole roll of polyimide film is sleeved on the rotating roller in the present invention, first, the distance control motor runs to drive the distance control gear on the output end of the distance control motor to rotate. The rotation of the distance control gear drives the two distance control racks to move symmetrically outward, thereby driving the two trimming devices to move symmetrically outward. Synchronously, it also drives the two limiting devices to move outward. Thus, when the operator sleeved the head end on the rotating sleeve, it will not cause obstruction or contact with the equipment to cause harm. At the same time, it is also convenient for the operator to perform the sleeving operation. After its head end is sleeved on the rotating roller, the two trimming devices are driven to move symmetrically inward by running the connecting distance control motor again, and the two trimming devices are moved to the trimming positions required by the product. At this time, the two limiting rollers are also on both sides of the product, and the two sides are limited by the two limiting rollers, so as to realize accurate trimming operation on the product, prevent the product from shifting, ensure the quality of the product. At the same time, the position of the screw trimming device and the screw limiting device can be adjusted by the operation of the distance control device, so that the device can be applicable to products of various widths and is convenient for wide use.

[0017] Fourth, when there are scraps generated after trimming both sides of the product in the present invention, the scraps on both sides are respectively passed through the corresponding guiding devices, and through the cooperation of the corresponding guiding rollers, the scraps on both sides move better downward. When the scraps on both sides are long enough, their lower ends are respectively placed into the corresponding feeding ports and flow into the crushing chamber. When the driving motor runs, the driving shaft rotates to drive the driving wheel to rotate. The driving wheel rotates to drive the driven wheel to rotate through the transmission belt, thereby driving the upper end of the crushing shaft to rotate inside the crushing chamber. The rotation of the crushing shaft drives the crushing blades to rotate, so as to realize the crushing of the scraps in the crushing chamber. Wait to take out through the discharge port for recycling later, avoiding waste of resources and scraps flying around to affect the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will, in conjunction with the drawings, detail the technical solutions provided by each embodiment of the present invention.

[0033] An edge trimming device for polyimide film production according to an embodiment of the present invention includes an edge trimming device 1, and also includes a workbench 11, a driving device 2, an adjusting device 3, a roller device 4, a distance control device 5, a limiting device 6, a guiding device 7, and a crushing device 8. The workbench 11 is disposed on a horizontal plane. The driving device 2 is disposed on the workbench 11. The adjusting device 3 is disposed on the workbench 11 and connected to the driving device 2. The roller device 4 is disposed at the side end of the driving device 2. The distance control device 5 is disposed at the side end of the roller device 4. There are two edge trimming devices 1, and the two edge trimming devices 1 are symmetrically disposed on the distance control device 5. There are two limiting devices 6, and the two limiting devices 6 are respectively disposed on the two edge trimming devices 1. There are two guiding devices 7, and the two guiding devices 7 are symmetrically disposed on the roller device 4. The crushing device 8 is disposed on the workbench 11 and is in transmission connection with the driving device 2. This device can limit the polyimide film during the edge trimming process, facilitating accurate edge trimming operations. Moreover, the polyimide film is driven synchronously as a whole, avoiding the generation of wrinkles. At the same time, it can also crush and collect the residual materials from the edge trimming.

[0034] Working principle: When trimming the polyimide film, first remove the rotating cover 291 on the unwinding rod 29 by rotating it. At this time, the whole roll of polyimide film needs to be sleeved on the unwinding rod 29, and then rotate the rotating cover 291 back onto the unwinding rod 29. In the same way, when sleeving the winding drum on the winding rod 38, then start the driving motor 22 to operate, driving the driving shaft 23 at the output end of the driving motor 22 to rotate on the corresponding driving frame 25. The rotation of the driving shaft 23 drives the driving helical gear 26 to rotate, and the rotation of the driving helical gear 26 drives the driven helical gear 28 to rotate, thereby driving the unwinding rod 29 to rotate on the fixed frame 27. The rotation of the unwinding rod 29 drives the whole roll of polyimide film on the unwinding rod 29 to rotate, so as to release a relative length of the head end of the whole roll of polyimide film and sleeve its head end on the rotating drum 42. At this time, trim the two sides of the product through the corresponding trimming device 1. When the trimming length is sufficient to sleeve the head end on the winding rod 38, the preliminary operation of the whole roll of polyimide film is completed. The rotation of the driving shaft 23 synchronously drives the rotating helical gear 36 to rotate, and the rotation of the rotating helical gear 36 drives the adjusting helical gear 37 to rotate, thereby driving the winding rod 38 to rotate to wind the trimmed product. At this time, the unwinding rod 29 and the winding rod 38 are in a state of rotating in opposite directions and in a synchronous rotation state, so that the polyimide film released by the unwinding rod 29 and the polyimide film wound by the winding rod 38 are of the same length. Therefore, during the operation of the polyimide film, it is always in a precise trimming operation state and will not loosen, wrinkle or break due to being too long or too short, thus improving the processing quality of the product;

[0035] During the trimming operation of the polyimide film, due to the different thicknesses and types of the whole roll of polyimide film, at this time, adjust the hydraulic cylinder 32 to operate, driving the adjusting plate 33 at the output end of the hydraulic cylinder 32 to move up or down, thereby driving the adjusting frame 34, adjusting column 35, adjusting helical gear 37, rotating helical gear 36 and winding rod 38 on the adjusting plate 33 to move up or down, so as to adjust the distance between the winding rod 38 and the unwinding rod 29 to be applicable to different thicknesses and different types of the whole roll of polyimide film;

[0036] When the head end of the whole roll of polyimide film is sleeved on the rotating roller 42, first, the distance control motor 52 runs to drive the rotation of the distance control gear 53 on the output end of the distance control motor 52. The rotation of the distance control gear 53 drives the two distance control racks 54 to move symmetrically outwards, thereby driving the two trimming devices 1 to move symmetrically outwards. Synchronously, it also drives the two limiting devices 6 to move outwards, so that when the operator sleeves the head end on the rotating sleeve, there will be no obstruction and no harm caused by contact with the equipment. At the same time, it is also convenient for the operator to carry out the sleeving operation. After its head end is sleeved on the rotating roller 42, the distance control motor 52 is driven to move again to drive the two trimming devices 1 to move symmetrically inwards, moving the two trimming devices 1 to the trimming positions required for the product. At this time, the two limiting rollers 62 are also on both sides of the product, and the two limiting rollers 62 limit both sides of it, thereby realizing accurate trimming operation on the product, preventing the product from shifting, ensuring the quality of the product. At the same time, by operating the distance control device 5, the position of the screw trimming device 1 and the screw limiting device 6 can be adjusted, so that this device can be applicable to products of various widths and is convenient for wide use;

[0037] When residues are generated after trimming both sides of the product, the residues on both sides are respectively passed through the corresponding guiding devices 7, and through the cooperation of the corresponding guiding rollers, the residues on both sides move better downwards. When the residues on both sides are long enough, their lower ends are respectively placed into the corresponding feeding ports 87, and they flow into the crushing chamber 85. When the driving motor 22 runs, the driving shaft 23 rotates to drive the driving wheel 81 to rotate. The rotation of the driving wheel 81 drives the driven wheel 82 to rotate through the transmission belt 83, thereby driving the upper end of the crushing shaft 84 to rotate inside the crushing chamber 85. The rotation of the crushing shaft 84 drives the crushing blades 86 to rotate, thereby realizing the crushing of the residues in the crushing chamber 85. Wait for the subsequent removal through the discharge port 88 for recycling, avoiding waste of resources and the residues flying around and affecting the operation.
