After adopting the above scheme, when in use, the positioning slide rail 1 is fixed on the machine table of the film punching equipment by conventional means. When punching, the film is passed through the space below the positioning substrate 5, and the film is fixed by the clamping mechanism 2. Then, the No. 1 manual bolt 4 is loosened, and the position of the clamping mechanism 2 is adjusted. The clamping mechanism 2 drives the guide slider 3 to move in the guide slide groove 11, and drives the reference block 31 to move at the same time. The reference block 31 is used to cooperate with the scale line 14 to accurately adjust the horizontal position of the clamping mechanism 2 for accurately locating the punching position. Finally, the positioning hole 51 is used to accurately locate the punching position, which greatly improves the accuracy of film punching.

[0041] It should be noted that in actual use, when punching a film roll, one end of the film is fixed by a clamping mechanism 2 and the other end is fixed by a winding machine. The winding machine is used to load and fix the film. When punching a film sheet, two sets of positioning devices need to be set up, and two clamping mechanisms 2 are used to fix the two ends of the film sheet respectively.

[0042] Optionally, by Figure 1As shown, in this embodiment, it also includes: fixed feet 7, fixed feet 7 are fixed at both ends of the positioning slide rail 1, and there are fixing holes 71 on the fixed feet 7. After adopting the above scheme, the positioning slide rail 1 can be fixed on the machine platform of the film punching equipment with bolts.

[0043] Preferably, by Figure 1 As shown, in this embodiment, it also includes: a No. 2 manual bolt 6, which penetrates the positioning substrate 5 and is connected to the positioning slide rail 1 by threaded engagement. The positioning substrate 5 is installed by the No. 2 manual bolt 6. The installation is stable and convenient, and it is also convenient to replace different positioning substrates 5 according to actual processing needs.

[0044] Preferably, by Figure 1 As shown, in this embodiment, the outer wall of the guide slider 3 abuts against the inner wall of the guide slot 11, further improving the stability of the clamping mechanism 2 and preventing the clamping mechanism 2 from shaking and affecting the accuracy of punching.

[0045] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, there are two symmetrically distributed positioning rails 1, and the clamping mechanism 2 is slidably connected to the inner sides of the two positioning rails 1 to ensure the stability of the clamping mechanism 2 and avoid the clamping mechanism 2 being offset due to the pulling of the film during punching, thereby affecting the accuracy of punching.

[0046] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the clamping mechanism 2 includes: a clamping rod 21, a clamping plate 22, an adjusting screw 23 and a handle 231. Guide sliders 3 are fixed at both ends of the clamping rod 21, and a clamping groove 211 is provided on the clamping rod 21. The clamping plate 22 is located in the clamping groove 211. The adjusting screw 23 is installed on the clamping rod 21 by threaded engagement, and the bottom end of the adjusting screw 23 is rotatably connected to the clamping plate 22. The handle 231 is fixed to the top end of the adjusting screw 23. After adopting the above scheme, when in use, the end of the film is placed in the clamping groove 211, and then the adjusting screw 23 is rotated by using the handle 231, so that the adjusting screw 23 pushes the clamping plate 22 downward under the action of the thread engagement, thereby clamping and fixing the film.

[0047] It should be noted that the aforementioned content mentioned that the processed film materials may be film rolls and film sheets. When punching the film roll, only a set of clamping mechanisms 2 are used to fix the free end of the film. When the punching position needs to be changed, the film is passed through the clamping groove 211 and re-clamped. When punching the film sheet, since the volume of the film is not large, when the punching position needs to be changed, punching at different positions can be achieved by changing the position of the punch of the punching equipment.

[0048] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, it also includes: a rubber anti-skid pad 24, and the rubber anti-skid pad 24 is bonded and fixed to the inner bottom surface of the clamping groove 211 and the bottom surface of the clamping plate 22. The rubber anti-skid pad 24 is flexible to ensure the stability and safety of the film after clamping and avoid wear.

[0049] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, it also includes: guide columns 221, two guide columns 221 are symmetrically fixed on the top surface of the clamping plate 22, and the top ends of the guide columns 221 pass through and extend to the outside of the clamping rod 21. The two guide columns 221 are used to guide the clamping plate 22 to improve the stability of the clamping plate 22.

When punching, the film is passed through the space below the positioning substrate 5, and the film is fixed by the clamping mechanism 2. Then, the No. 1 manual bolt 4 is loosened, and the position of the clamping mechanism 2 is adjusted. The clamping mechanism 2 drives the guide slide block 3 to move in the guide slide groove 11, and drives the reference block 31 to move at the same time. The horizontal position of the clamping mechanism 2 is accurately adjusted by using the reference block 31 in conjunction with the scale line 14 to accurately locate the punching position. After the adjustment is completed, the No. 1 manual bolt 4 is tightened;

[0052] Finally, the location of the punching hole is accurately located by using the positioning hole 51, so that the punch of the punching device passes through the positioning hole 51 and acts on the film to achieve punching, which greatly improves the accuracy of the film punching;

[0053] The positioning substrate 5 is installed by means of the No. 2 manual bolt 6 , which is stable and convenient to install, and it is also convenient to replace different positioning substrates 5 according to actual processing needs.
