Description

Technical Field

[0001] This utility model relates to the field of polyimide film processing technology, specifically to a slitting device for polyimide film processing that facilitates the restriction of the film. Background Technology

[0002] Polyimide film (PI film) is a high-performance insulating material made from pyromellitic dianhydride and diaminodiphenyl ether through polycondensation, casting, and imidization processes. It has a temperature resistance range of -269℃ to 400℃, high mechanical strength, and stable dielectric properties. It is mainly divided into thermoplastic and thermosetting types and is widely used in flexible circuit boards, motor insulation, aerospace, and other fields. In the processing of polyimide film, it needs to be slit. Chinese patent CN219027588U discloses a slitting device for polyimide film processing, including a slitting table and a support frame connected to the top of the slitting table. The support frame is connected to a cutting mechanism for film cutting. The cutting mechanism includes an electric cylinder, oppositely arranged blade columns, oppositely arranged protective boxes, and oppositely arranged cutting blades. The electric cylinder is used to drive the blade columns to rise and fall. The pressure roller of this invention can flatten the film, ensuring the flatness of the film and providing a good foundation for subsequent synchronous cutting of both sides of the film. The cut is relatively flat, and the width after cutting is relatively uniform, making it highly practical.

[0003] In the existing technology, it is not convenient to adjust the slitting width. Moreover, there are many different types of polyimide films, which makes it difficult to adjust the slitting width of the film according to the usage requirements, thus reducing the applicability of the slitting device. Therefore, we propose a slitting device for polyimide film processing that is convenient for restricting the film. Utility Model Content

[0004] The purpose of this invention is to provide a slitting device for polyimide film processing that facilitates the restriction of the film, thereby solving the problem mentioned in the background art that it is inconvenient to adjust the slitting width, and that polyimide films come in a variety of models, making it difficult to adjust the slitting width according to usage requirements, thus reducing the applicability of the slitting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slitting device for processing polyimide films that facilitates film restriction, comprising a worktable, support columns, a mounting frame, a control switch, and an adjusting slitting mechanism. The support columns are fixed to the four corners of the bottom of the worktable, the mounting frame is fixed to the top edge of the worktable, the control switch is fixed to one side of the mounting frame, and the adjusting slitting mechanism is disposed inside the mounting frame. A placement plate is fixed to the bottom between the two inner sides of the mounting frame. The adjusting slitting mechanism includes an electric telescopic rod symmetrically extending through and fixed to the top of the mounting frame. A connecting frame is fixed to the output shaft end of the electric telescopic rod. A first screw is fixed to the middle between the two inner sides of the connecting frame. Sliding rods are symmetrically fixed between the two inner sides of the connecting frame. Several sliding blocks are sleeved on the outer side of the first screw. A connecting groove is opened on one side of each sliding block. A cutting wheel is fixed to the bottom of each sliding block by bolts. Several knobs are evenly screwed onto the outer wall of the first screw. A connecting block is symmetrically fixed to one side of each knob.

[0006] As a further description of the above technical solution: The adjustment and cutting mechanism also includes a pointer fixed to the middle of one side of the slider and a scale on the top of one side of the connecting frame.

[0007] As a further description of the above technical solution: The connecting block is connected to the inside of the connecting groove, and the slider slides on the outside of the slide rod.

[0008] As a further description of the above technical solution: The input end of the electric telescopic rod is electrically connected to the output end of an external power source, and the electric telescopic rod is electrically connected to the control switch.

[0009] As a further description of the above technical solution: A limiting mechanism is provided on the outer side of the workbench. The limiting mechanism includes a symmetrical moving groove that runs through the top of the workbench. A moving block slides inside the moving groove. A limiting plate is fixed to the top of the moving block. A first connecting seat is fixed to the bottom center of the moving block. A connecting rod rotates inside the first connecting seat. A concave frame is fixed to the bottom center of the workbench. A drive motor is fixed to the inner bottom of the concave frame. A second screw is fixed to the end of the output shaft of the drive motor. A moving plate is screwed to the outer wall of the second screw. A second connecting seat is fixed to the middle of both sides of the moving plate.

[0010] As a further description of the above technical solution: The limiting mechanism also includes a first limiting rod fixed to the middle of both sides of the moving groove, and a second limiting rod symmetrically fixed to the bottom of the worktable.

[0011] As a further description of the above technical solution: The moving block slides on the outside of the first limiting rod, the moving plate slides on the outside of the second limiting rod, one end of the connecting rod rotates inside the second connecting seat, the input end of the drive motor is electrically connected to the output end of the external power supply, and the drive motor is electrically connected to the control switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This polyimide film processing slitting device, which facilitates the restriction of thin films, allows for adjustment by rotating a knob connected to a first screw. As the knob rotates, it moves to the outside of the first screw. The connecting block and connecting groove move a slider, thereby adjusting the position of the cutting wheels. A pointer and scale indicate the distance between the two cutting wheels, thus adjusting the film cutting width. This allows for easy adjustment of the film cutting width according to usage requirements, expanding the applicability of the slitting device.

[0013] This polyimide film processing slitting device, which facilitates the restriction of the film, starts the drive motor by a control switch, which drives the second screw to rotate. The rotation of the second screw causes the moving plate to descend outside the second limiting rod, thereby causing the second connecting seat to descend. This, in turn, causes the connecting rod to deflect vertically, moving the first connecting seat and causing the moving block to slide outside the first limiting rod. This brings the limiting plates closer together, allowing them to adhere to both sides of the film and restrict the film, thus preventing the film from deviating during slitting, ensuring slitting stability, and improving the practicality of the device.

[0020] In summary, during adjustment, the knob 570 is rotated, and the knob 570 is screwed to the first screw 530. When the knob 570 rotates, it moves to the outside of the first screw 530. With the connection block 571 and the connection groove 551, the slider 550 is moved, thereby adjusting the position of the cutting wheel 560.

[0023] Please refer to it again. Figure 2 The input end of the electric telescopic rod 510 is electrically connected to the output end of the external power supply, and the electric telescopic rod 510 is electrically connected to the control switch 400.

[0024] Please refer to it again. Figure 4 A limiting mechanism 600 is provided on the outer side of the workbench 100. The limiting mechanism 600 includes a moving groove 610 symmetrically opened through the top of the workbench 100. A moving block 620 slides inside the moving groove 610. A limiting plate 630 is fixed to the top of the moving block 620. A first connecting seat 640 is fixed to the middle of the bottom of the moving block 620. A connecting rod 650 rotates inside the first connecting seat 640. A concave frame 660 is fixed to the middle of the bottom of the workbench 100.

A moving plate 680 is screwed to the outer wall of the second screw 671. A second connecting seat 690 is fixed to the middle of both sides of the moving plate 680.

[0025] Please refer to it again. Figure 4 The limiting mechanism 600 also includes a first limiting rod 611 fixed to the middle of both sides of the moving groove 610, and a second limiting rod 681 symmetrically fixed to the bottom of the worktable 100.

[0026] Please refer to it again. Figure 5 The moving block 620 slides on the outside of the first limiting rod 611, the moving plate 680 slides on the outside of the second limiting rod 681, one end of the connecting rod 650 rotates inside the second connecting seat 690, the input end of the drive motor 670 is electrically connected to the output end of the external power supply, and the drive motor 670 is electrically connected to the control switch 400.

[0027] In summary, by starting the drive motor 670 through the control switch 400, the second screw 671 is driven to rotate. The rotation of the second screw 671 causes the moving plate 680 to descend outside the second limit rod 681, thereby causing the second connecting seat 690 to descend. This, in turn, causes the connecting rod 650 to deflect vertically, moving the first connecting seat 640. This causes the moving block 620 to slide outside the first limit rod 611, bringing the limit plates 630 closer together. This allows the limit plates 630 to adhere to both sides of the film, restricting the film and preventing it from deviating during slitting, ensuring slitting stability and improving the practicality of the device.

[0028] In practical use, when cutting the film, those skilled in the art pass it through the mounting bracket 300 and place it on the placement plate 310. The drive motor 670 is started via the control switch 400, causing the second screw 671 to rotate. This rotation of the second screw 671 lowers the moving plate 680 outside the second limiting rod 681, causing the second connecting seat 690 to descend. This, in turn, causes the connecting rod 650 to deflect vertically, moving the first connecting seat 640 and causing the moving block 620 to slide outside the first limiting rod 611. This brings the limiting plates 630 closer together, allowing them to adhere to both sides of the film and restrict its movement. Then, the knob 57 is rotated. 0, while knob 570 is screwed to first screw 530. When knob 570 is rotated, it moves outside of first screw 530. Using connecting block 571 and connecting groove 551, slider 550 is moved, thereby adjusting the position of cutting wheel 560. Using pointer 580 and scale 590, the distance between the two cutting wheels 560 is read, thereby adjusting the width of film cutting. The drive motor 670 is turned off by control switch 400. The electric telescopic rod 510 is moved by control switch 400, which drives connecting frame 520 to descend, so that cutting wheel 560 fits with film, pulls film, and cuts film using cutting wheel 560.
