[0034] Specifically, a silica gel scraper 13 is arranged below the smoothing plate 92, and the silica gel scraper 13 is fixedly connected with the smoothing plate 92.

[0035] Through the above technical solution, by setting a silicone scraper 13, since the silicone scraper 13 is relatively soft, it can scratch the surface of the metal film while smoothing the metal film.

[0036] Specifically, the two ends of the film roller 11 are provided with limiting plates 15, which are sleeved on the film roller 11 and fixedly connected to it.

[0037] By using the above technical solution, the limiting plate 15 can limit the film roller 11 in the connecting frame 7, preventing the film roller 11 from moving too far between the connecting frames 7, which would cause the film roller 11 to detach from the auxiliary rollers 83.

[0038] Working principle: In use, firstly, the film roller 11 for pre-cutting metal film is placed between the two auxiliary rollers 83 on the inner bottom of the upper part of the connecting frame 7. Then, by turning the handle 84, the threaded rod 81 is rotated, pushing the pressure plate 82 to move the auxiliary rollers 83 below it closer to the auxiliary rollers 83 on the inner bottom of the upper part of the connecting frame 7, thus locking both ends of the film roller 11 between the four auxiliary rollers 83, thereby fixing the position of the film roller 11. Then, by pulling the pull rod 93, the smoothing plate 92 is pulled up against the force of the spring 94, and one end of the metal film is pulled out from the film roller 11, passing through the transition roller 12 and under the smoothing plate 92. Then, the pull rod 93 is released, and under the force of the spring 94, the silicone scraper 13 under the smoothing plate 92 is pushed to contact the metal film, thereby cutting the metal film. After smoothing the surface, continue pulling one end of the metal film, pulling it from below the cutting blade 5 to the other end above the worktable 1. Then, by starting the cylinder 3, the blade holder 4 is moved, causing the blade holder 4 to push the cutting blade 5 and the pressure plate 101 downwards. Under the force of the pressure spring 103, the pressure plate 101 can be pushed to contact the metal film before the cutting blade 5 and press it firmly. Then, under the continuous downward pressure of the cylinder 3, the pressure spring 103 can be compressed, causing the cutting blade 5 to cut the metal film through the through groove 14. After the cutting is completed, the cylinder 3 drives the blade holder 4 to move, causing the blade holder 4 to move the cutting blade 5 and the pressure plate 101 upwards. Then, the metal film can be pulled again to cut it. When the cutting blade 5 is maintained later, the cutting blade 5 can be removed from the blade holder 4 by removing the bolt 6.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
