Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a PI cover film cutting device. Background Technology

[0002] In current industrial manufacturing and processing, PI (polyimide) cover film, as a high-performance material, is widely used in the manufacturing process of electronic products due to its excellent insulation, high-temperature resistance, and mechanical strength. The demand for PI cover film is particularly increasing in consumer electronics products such as smartphones, tablets, and wearable devices, where it is used for display screen protection films and circuit board insulating layers. To meet the demands of large-scale production and efficient processing, the cutting process of PI cover film is especially important.

[0003] Traditional PI cover film cutting devices typically employ an integrated cutting blade design. Since the cutting blade is tightly connected to the main structure of the cutting device, if the cutting blade becomes worn or damaged and needs to be replaced, the entire cutting device must be disassembled. This not only increases the difficulty and complexity of maintenance but may also lead to damage or loosening of other components, thereby affecting the overall performance and accuracy of the cutting device. Utility Model Content

[0004] The purpose of this invention is to provide a PI cover film cutting device to solve the problem mentioned in the background art that traditional PI cover film cutting devices usually adopt an integrated cutting scissor design. Since the cutting scissor is closely connected to the main structure of the cutting device, once the cutting scissor is worn or damaged and needs to be replaced, the entire cutting device needs to be disassembled. This not only increases the difficulty and complexity of maintenance, but may also lead to damage or loosening of other components, thereby affecting the overall performance and accuracy of the cutting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PI cover film cutting device, comprising a base, a housing fixedly connected to the top of the base, an outer support plate fixedly connected to the top position of one side of the housing, a movable plate movably connected to the bottom of the outer support plate, an installation plate fixedly connected to the bottom of the movable plate, a cutter provided at the bottom of the installation plate, a connecting plate fixedly connected to the top of the cutter, an installation groove formed at the center of the bottom of the installation plate, the top of the connecting plate penetrating into the interior of the installation groove and engaging with the installation groove, inner plates fixedly connected to the bottom positions of both sides of the installation plate corresponding to the installation groove, a limiting block provided at the center of the opposite side of each of the two inner plates, a limiting groove formed at the bottom positions of both sides of the connecting plate, the opposite sides of the two limiting blocks penetrating into the interior of the two limiting grooves and engaging with the limiting grooves, and fixing bolts threadedly connected to the center positions of both sides of the installation plate, one side of the fixing bolt penetrating through the connecting plate and the positioning plate and threadedly connected to the positioning plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This PI film cutting device, through the snap-fit ​​design of the connecting plate and the mounting groove, and the cooperation between the limiting block and the limiting groove, enables the quick installation and disassembly of the cutting blades. This design allows for easy removal and replacement of the cutting blades without disassembling the entire cutting device when the blades are worn or damaged; simply loosening the fixing bolts is sufficient. This significantly reduces the difficulty and complexity of maintenance. The movable groove inside the inner plate, with a return spring connected to the limiting block, ensures the stability and positioning accuracy of the cutting blades during installation. The elastic force of the return spring ensures the limiting block fits tightly within the limiting groove, effectively preventing the cutting blades from shaking or shifting during use. Simultaneously, the anti-slip strip within the limiting groove further enhances the friction between the limiting block and the limiting groove, improving the overall stability and accuracy of the cutting device. The snap-fit ​​design between the bottom plate of the top plate and the top groove of the fixed base, along with the cooperation between the fixed plate and the fixed groove, achieves a stable connection between the movable plate and the mounting plate. This design not only enhances the flexibility and applicability of the cutting device but also ensures stability and safety during the cutting process. Attached Figure Description

[0016] A positioning plate 10 is fixedly connected to the center of the bottom of the movable plate 4. A positioning groove 9 is opened at the center of the top of the connecting plate 7. The bottom of the positioning plate 10 passes through the interior of the positioning groove 9 and is engaged with the positioning groove 9.

[0017] The inner plate 12 has a movable groove 13 inside. The opposite sides of the two limiting blocks 14 pass through the interior of the two movable grooves 13 and are slidably connected to the movable grooves 13. A return spring 15 is fixedly connected to the inner wall of the movable groove 13, and one side of the return spring 15 is fixedly connected to the limiting block 14.

[0018] An anti-slip strip 16 is fixedly connected to the center of the limiting groove 11, and the center of the two limiting blocks 14 on opposite sides contacts the anti-slip strip 16.

[0019] Top plates 18 are fixedly connected to the bottom positions on both sides of the movable plate 4, and bottom plates 19 are fixedly connected to the top positions on both sides of the mounting plate 5. A fixing seat 20 is fixedly connected to the top of the bottom plate 19, and a locking plate 21 is fixedly connected to the center of the bottom of the top plate 18. A locking groove 22 is opened in the center of the top of the fixing seat 20, and the bottom of the locking plate 21 extends through the inside of the locking groove 22 and engages with the locking groove 22.

[0020] A fixing groove 23 is provided at the center of the bottom of the card plate 21. A fixing plate 24 is fixedly connected to the center of the bottom of the card groove 22. The top of the fixing plate 24 extends through the inside of the fixing groove 23 and engages with the fixing groove 23.

[0021] The bottom of the base plate 19 is threaded with a fastening bolt 25. The top of the fastening bolt 25 passes through the fixing seat 20, the fixing plate 24 and the clamping plate 21 in sequence and is threadedly connected to the clamping plate 21.

[0022] Working Principle: First, align the connecting plate 7 at the top of the cutting scissors 6 with the mounting groove 8 at the bottom of the mounting plate 5 and insert it to achieve a preliminary physical connection. Simultaneously, the positioning groove 9 at the top of the connecting plate 7 engages with the positioning plate 10 fixed at the bottom of the movable plate 4. The bottom of the positioning plate 10 extends into the positioning groove 9, ensuring the initial positioning of the cutting scissors 6 during installation. After the connecting plate 7 is inserted into the mounting groove 8, the limiting grooves 11 on both sides contact the limiting blocks 14 on the inner plate 12 inside the mounting plate 5. Under the action of the return spring 15, the limiting blocks 14 slide into the limiting grooves 11 and lock in place. At the same time, the center of the limiting blocks 14 contacts the anti-slip strip 16 inside the limiting groove 11, increasing friction and preventing the cutting scissors 6 from shaking during use. This design not only ensures the stability of the cutting scissors 6 after installation but also provides a certain degree of stability through the elastic force of the return spring 15. The buffer and adjustment space is designed to accommodate different cutting needs. After the cutting scissors 6 are initially installed and positioned, the fixing bolts 17 on both sides of the mounting plate 5 are rotated to pass through the connecting plate 7 and be threadedly connected to the positioning plate 10. The tightening effect of the fixing bolts 17 further strengthens the connection between the cutting scissors 6 and the mounting plate 5, ensuring stability and accuracy during the cutting process. The bottom of the top plates 18 on both sides of the movable plate 4 is fixed with clamping plates 21. These clamping plates 21 cooperate with the slots 22 on the top of the fixing seat 20 on the mounting plate 5 to achieve initial clamping. The fixing grooves 23 at the bottom of the clamping plates 21 are further clamped with the fixing plates 24 at the bottom of the slots 22, increasing the stability of the connection. Finally, the fastening bolts 25 are rotated to pass through the fixing seat 20, the fixing plate 24, and the clamping plates 21 and be threadedly connected to the clamping plates 21, achieving the final stable connection between the movable plate 4 and the mounting plate 5.

[0023] In summary, this PI cover film cutting device, through the snap-fit ​​design of the connecting plate 7 and the mounting groove 8, and the cooperation of the limiting block 14 and the limiting groove 11, enables the quick installation and disassembly of the cutting scissors 6. This design allows the cutting scissors 6 to be easily removed and replaced simply by loosening the fixing bolts 17 when wear or damage occurs, without disassembling the entire cutting device. This greatly reduces the difficulty and complexity of maintenance. By opening a movable groove 13 inside the inner plate 12 and setting a return spring 15 connected to the limiting block 14, the stability and positioning accuracy of the cutting scissors 6 during installation are ensured. The elasticity of the return spring 15... The function of the limiting block 14 is to fit tightly into the limiting groove 11, effectively preventing the cutting scissors 6 from shaking or shifting during use. At the same time, the anti-slip strip 16 in the limiting groove 11 further enhances the friction between the limiting block 14 and the limiting groove 11, improving the overall stability and accuracy of the cutting device. Through the snap-fit ​​design of the card plate 21 at the bottom of the top plate 18 and the card slot 22 at the top of the fixed seat 20, as well as the cooperation between the fixed plate 24 and the fixed groove 23, a stable connection between the movable plate 4 and the mounting plate 5 is achieved. This design not only enhances the flexibility and applicability of the cutting device, but also ensures the stability and safety during the cutting process.
