Description

Technical Field

[0001] The utility model relates to the technical field of polyimide film production, in particular to a polyimide film high-efficiency slitting device. Background Art

[0002] Polyimide film offers excellent mechanical, electrical, and chemical properties, as well as high radiation resistance and high and low-temperature resistance. In actual manufacturing, different manufacturers have varying requirements for product specifications and widths, requiring manufacturers to slit finished film to produce polyimide film of appropriate widths to meet diverse customer needs.

[0003] Existing slitting mechanisms generally use a knife head above the polyimide film to slit the polyimide film. Due to the excellent mechanical properties of the polyimide film, the slitting equipment with one knife head does not slit the polyimide film thoroughly. The polyimide film after slitting is prone to "broken bones and connected tendons", which reduces the slitting efficiency. Utility Model Content

[0024] Example

[0025] The utility model provides a technical solution, a polyimide film high-efficiency slitting device, combined with Figure 1-5 As shown, it includes a slitting box 1, two slitting blades 11 and a driving assembly.

[0026] The slitting box 1 is provided with a cutting opening 3 to provide space for slitting the polyimide film.

[0027] The two slitting blades 11 are respectively vertically slidably arranged on the inner wall of the slitting box 1, and the two slitting blades 11 are respectively located on the upper and lower sides of the cutting port 3, so that the polyimide film can be double-sided slitting, reducing the slitting obstacles caused by the hardness of the polyimide film itself, and can reduce the phenomenon of ribs appearing on the polyimide film during slitting, thereby improving the slitting accuracy of the polyimide film.

[0028] The driving assembly is arranged in the accommodating cavity of the slitting box 1, and is used to drive the two slitting blades 11 to fit together or separate. The driving assembly includes two traction plates 9 rotatably installed in the accommodating cavity of the slitting box 1 through a support rod 7. One end of the two traction plates 9 is movably connected with the two slitting blades 11 respectively. Two driving gears 5 are rotatably installed in the accommodating cavity of the slitting box 1, and the two driving gears 5 are meshed and connected, so that it is convenient for the driving motor to drive the two driving gears 5 to rotate. A driving motor for driving one of the driving gears 5 to rotate is provided on the outside of the slitting box 1, and the two driving gears 5 are movably connected at the middle position of the two traction plates 9 respectively.

[0029] When in use, the polyimide film to be cut, which is spread flat on the carrier 4, is moved to the cutting opening 3, and the driving motor is started to drive one of the driving gears 5 to rotate. The rotating driving gear 5 drives the other driving gear 5 meshed with it to rotate. The two rotating driving gears 5 drive the traction plate 9 through the driving rod 6 to drive the slitting blade 11 to move, so that the two slitting blades 11 are fitted to cut the polyimide film on both sides. The cut polyimide film slides from the guide plate 2 into the collection container.

[0030] Furthermore, a fixed block 8 for installing a slitting blade 11 is provided in the accommodating cavity of the slitting box 1, and a guide groove 12 with a trapezoidal structure is provided on the fixed block 8. A guide block 14 adapted to the slitting groove 12 is slidably provided in the guide groove 12. By setting the guide groove 12 and the guide block 14, the stability of the slitting blade 11 during up and down displacement slitting is improved, and the flatness of the slitting surface of the polyimide film is improved. The outer surface of the guide block 14 is provided with a connecting block 13 connected to the slitting blade 11, and the connecting block 13 and the guide block 14 are an integrally formed structure, thereby improving the connection strength between the two.

[0031] Furthermore, a driven rod 10 connected to the traction plate 9 is fixed on the connecting block 13, a driving rod 6 connected to the traction plate 9 is fixed on the driving gear 5, and a driving groove 15 for displacement of the driving rod 6 and a driven groove 16 for displacement of the driven rod 10 are respectively provided on the traction plate 9. The rotating driving gear 5 drives the traction plate 9 through the driving rod 6 to drive the slitting blade 11 to move up and down.

[0032] Furthermore, a supporting frame 4 for laying out the polyimide film is provided on the slitting box body 1 on one side of the cutting port 3, and a material guide plate 2 is provided on the slitting box body 1 on the other side of the cutting port 3. The material guide plate 2 gradually tilts downward from the side close to the slitting box body 1 to the side away from the slitting box body 1, so that the slit polyimide film can slide into the collection container, making it easy to collect the slit polyimide film.
