Description

Technical Field

[0001] This utility model belongs to the field of thin film processing technology, specifically a polyimide film edge cutting device. Background Technology

[0002] Polyimide film is a high-performance polymer material with excellent high-temperature resistance, low-temperature resistance, radiation resistance, and insulation properties, and is widely used in aerospace, electronics, automotive, and other fields. During the production of polyimide film, the edges need to be cut to ensure consistent film width and improve product quality.

[0003] Currently, existing polyimide film edge-cutting devices have some shortcomings in use. On the one hand, it is not convenient to quickly install and fix the outer cylinder of the take-up roller, making the operation more troublesome for workers and reducing work efficiency. On the other hand, the position of the cutter is fixed and cannot be adjusted according to the width of the film, thus limiting its applicable range. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a rotating knob to drive a worm gear to rotate, which in turn drives a matching worm wheel to rotate. The worm wheel then drives a rotating rod to rotate, which in turn drives a bidirectional lead screw to rotate. The bidirectional lead screw drives a threaded slider to move closer to each other, and the slider, through a connecting rod, drives an arc plate to move further away from each other. This allows for the disassembly and assembly of the cylinder, facilitating operation and improving the work efficiency of the staff.

[0013] 2. This new type of rotary handwheel drives the first lead screw to rotate, which in turn drives the threaded T-block to move to one side. The T-block then drives the edge trimmer to move to one side, thus enabling the edge trimmer to move laterally and adjust its position. This design is suitable for trimming polyimide films of different widths, expanding the applicability of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figures 1-4 The present invention includes a base 1, with a cavity 12 inside the base 1. A first lead screw 2 is rotatably connected to the inner wall of the cavity 12. One end of the first lead screw 2 extends through to the outside of the base 1 and is fixedly connected to a handwheel 3. A T-shaped block 4 is threadedly connected to the outside of the first lead screw 2. The top of the T-shaped block 4 extends through to the outside of the base 1 and is fixedly connected to a trimming machine 5. A U-shaped frame 6 is fixedly installed on one side of the top of the base 1. Two sets of transmission rods 7 are symmetrically rotatably connected inside the U-shaped frame 6. A motor 8 is fixedly installed on one side of the U-shaped frame 6. The output end of the motor 8 extends through to the inside of the U-shaped frame 6 and is fixedly connected to one of the sets of transmission rods 7. One end of the transmission rod 7 extends through to the outside of the U-shaped frame 6 and is provided with a positioning mechanism 10.

[0023] The positioning mechanism 10 includes a U-shaped seat 1001 fixedly installed at one end of the transmission rod 7. A rotating rod 1002 is rotatably connected to the inner wall of the U-shaped seat 1001. A worm gear 1003 is fixedly sleeved on the outside of the rotating rod 1002. A worm 1004 adapted to the worm gear 1003 is rotatably connected to the inner wall of the U-shaped seat 1001. The top end of the worm 1004 extends through to the outside of the U-shaped seat 1001 and is fixedly connected to a knob 1005. A take-up drum 1006 is fixedly connected to one side of the U-shaped seat 1001. The internal part of 1006 is rotatably connected to a bidirectional lead screw 1007. Both sides of the bidirectional lead screw 1007 are screwed with sliders 1008. Both sides of the two sliders 1008 are rotatably connected to connecting rods 1009. One side of each connecting rod 1009 extends through to the outside of the take-up drum 1006 and is rotatably connected to an arc plate 1010. Two sets of telescopic limit rods 1011 are symmetrically connected to the corresponding sides of the two arc plates 1010. One side of the telescopic limit rod 1011 is fixedly connected to the take-up drum 1006.

[0024] Two sets of telescopic limiting rods 1011 are symmetrically connected to one side of the two arc-shaped plates 1010. They have the functions of support and limiting. They extend and retract synchronously with the arc-shaped plates 1010 during the opening and closing process, providing radial support for the arc-shaped plates 1010 and preventing them from shifting due to force.

[0025] One end of the bidirectional lead screw 1007 extends through to the outside of the winding drum 1006 and is fixedly connected to one end of the rotating rod 1002. A rectangular hole 11 is provided at the top of the base 1. The outside of the T-block 4 slides in contact with the inner wall of the rectangular hole 11. Two sets of transmission rollers 9 are symmetrically rotatably connected inside the U-shaped frame 6. One end of the transmission roller 9 extends through to the outside of the U-shaped frame 6.

[0026] The outer side of the T-block 4 maintains a tight sliding contact with the inner wall of the rectangular hole 11, providing a stable guide trajectory for the T-block 4 and restricting its freedom of movement in the horizontal direction, so that it can only slide in a straight line along the extension direction of the rectangular hole 11, avoiding the impact on the running accuracy of the entire structure due to offset.

[0027] Working principle: In use, the hollow cylinder and the film-wound cylinder are respectively fitted onto the outside of the two sets of take-up drums 1006. By rotating the knob 1005, the knob 1005 drives the worm gear 1004 to rotate, the worm gear 1004 drives the matching worm wheel 1003 to rotate, the worm wheel 1003 drives the rotating rod 1002 to rotate, the rotating rod 1002 drives the double-acting screw 1007 to rotate, and the double-acting screw 1007 drives the threaded slider 1008 to move closer to each other. The slider 1008 is connected to the connecting rod 1 009 drives the arc plate 1010 to move away from each other, which can position the cylinder. Then, the external controller starts the motor 8 and the edge trimmer 5. The motor 8 drives the hollow cylinder to rotate, and the hollow cylinder winds up the film. At the same time, the edge trimmer 5 trims the film. The handwheel 3 is rotated, and the handwheel 3 drives the first lead screw 2 to rotate. The first lead screw 2 drives the threaded T-block 4 to move to one side. The T-block 4 drives the edge trimmer 5 to move to one side, which can drive the edge trimmer 5 to move laterally, thereby adjusting the position of the edge trimmer 5.
