[0001] The utility model belongs to the related technical field of protection film cutting, and particularly relates to a film cutting device. BACKGROUND

[0002] The surface of the stainless steel plate material purchased on the market is usually covered with a layer of protective film, so that when the stainless steel plate material needs to be cut, the high temperature generated when the stainless steel plate material is laser cut will cause the protective film on the stainless steel plate material to bubble, deform, and burn, which seriously affects the subsequent mold forming of the plate material, so the protective film of the stainless steel plate material must be cut before cutting to ensure that the laser cutting track is not covered with a protective film.

The terminology used in the description of the present application only for the purpose of describing specific embodiments and is not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] The cutting film device 100 claimed in the present application is used for cutting the protective film (not shown in the figure) on the stainless steel plate (not shown in the figure). Of course, the substrate for carrying the protective film is not limited to the stainless steel plate, but can also be other substrates, such as sheet metal, copper plate, etc.

[0042] As Figures 1 to 3As shown, the film cutting device 100 provided by an embodiment of the present application comprises a film cutting assembly 10 and a driving assembly 20. The film cutting assembly 10 comprises a support seat 11, a concentric shaft 12, a cutter wheel 13 and a support wheel set 14. The concentric shaft 12 is installed in the support seat 11. The cutter wheel 13 and the support wheel set 14 are sleeved on the concentric shaft 12 in series. The radius of the cutter wheel 13 is greater than the radius of the support wheel 141 in the support wheel set 14, and the difference between the two radii is equal to the thickness of the protective film. The driving assembly 20 is in driving connection with the support seat 11. The driving assembly 20 can drive the support seat 11 to move in the vertical direction and the horizontal direction respectively, and make the cutter wheel 13 cut the protective film. That is, when the film cutting device 100 cuts the protective film with the cutter wheel 13, the support wheel 141 in the support wheel set 14 can abut against the part of the protective film that has not been cut, thereby playing an auxiliary supporting role. Here, the driving assembly 20 drives the support seat 11 to move in the vertical direction, so as to control whether the cutter wheel 13 abuts against the protective film. The driving assembly 20 drives the support seat 11 to move in the horizontal direction, so as to move the cutter wheel 13 abutting against the protective film on the protective film, and achieve the purpose of cutting the protective film.

[0043] It can be understood that the concentric shaft 12 is used to carry the cutter wheel 13 and the support wheel set 14, so that the film cutting assembly 10 has a compact structure and a small turning angle. When the film cutting device 100 works, the support wheel set 14 can be used to assist in supporting the cutter wheel 13. In this way, on the one hand, the cutter wheel 13 can be prevented from damaging the stainless steel plate below the protective film during the cutting process, and the turning angle of the cutter wheel 13 is small. On the other hand, the support wheel set 14 can press the part of the protective film that has not been cut by the cutter wheel, and make the film edge of the protective film flat, thereby ensuring the effect of the diaphragm and improving the film cutting efficiency.

[0044] As shown in the figure, Figure 3 The support seat 11 comprises a first fixed plate 111 and a second fixed plate 112. The first fixed plate 111 and the second fixed plate 112 are symmetrically arranged on the two outer sides of the concentric shaft 12.

Thus, the support wheel set 14 can press the two sides of the protective film cut by the cutter wheel 13 on the basis of assisting the cutter wheel 13, so as to ensure the flatness of the film edge of the protective film. Of course, in other embodiments, the number of the support wheels 141 of the support wheel set 14 can also be configured as one, three or even more, which will not be described here.

The second limiting member 313 is partially inserted into the support seat 11 upward in the vertical direction and connected with the guide pin body 311. The guide pin body 311 is in sliding fit with the driving seat 21. That is, the guide limiting pin 31 can realize the support of the support seat 11 by the guide pin body 311, and the reciprocating movement of the support seat 11 relative to the driving seat 21 is guided by the sliding fit between the guide pin body 311 and the driving seat 21. Here, the first limiting member 312 and the second limiting member 313 are configured as bolts or screws, and are connected with the guide pin body 311 in a threaded connection manner.
