Description

Technical Field

[0001] The utility model relates to the field of automobile protective film production, and more specifically, to a cutting device for automobile protective film production. Background Art

[0002] Automobile protective films, as a kind of automobile protection products, are mainly divided into two categories: heat insulation films pasted on automobile glass windows and protective films pasted on automobile paint surfaces. When producing protective films, a cutting device is needed to cut the protective films into required sizes, so as to facilitate the construction of workers.

[0003] After retrieval, in the prior art, a Chinese patent with the patent publication number CN217620951U discloses "a cutting device for automobile protective film production, including a base, a lifting mechanism and a replacement mechanism. The replacement mechanism includes a mounting frame, a driving component, two sleeves, two clamping plates and a blade. The blade can be driven by the lifting mechanism to cut the protective film. When the blade needs to be replaced, the driving component is started, and the driving component works to drive the two sleeves to move away from each other. The two sleeves drive the two clamping plates to move. At this time, the blade can be removed, and then a new blade is inserted into the two clamping plates. The driving component is started to reverse, driving the two sleeves to move closer to each other. The two sleeves drive the two clamping plates to move towards the side close to the blade and clamp the blade, thus completing the replacement of the blade, and solving the problem that when replacing the blade of the existing cutting equipment, multiple screws on the cutting equipment need to be removed one by one, increasing the workload of the staff", but there are still the following defects:

[0004] (1) However, when this device is in use, it cannot cut the protective film into a fixed length. When the film applicator constructs, it is still necessary to frequently measure and cut, which complicates the construction steps and thus reduces the construction efficiency;

[0005] (2) However, when this device is in use, the user still needs to manually push the protective film under the blade. Therefore, when cutting the protective film, if a safety accident occurs, it still needs to be improved.

[0006] Therefore, we make improvements on this and propose a cutting device for automobile protective film production. Content of the Utility Model

[0034] Specifically, as Figure 4 shown, a guiding groove 4 is formed on the inner wall of the support frame 207, and both ends of the cutting knife 209 are located inside the guiding groove 4 and are slidably connected to the guiding groove 4.

[0035] Specifically, as Figure 4 shown, a placing groove 5 is formed on the top of the workbench 1, and a conveyor belt 6 for conveying the cut protective film is arranged inside the placing groove 5.

[0036] Specifically, as Figure 1 shown, a guiding frame 7 for guiding the discharged protective film is bolted to one end of the workbench 1, and a storage box 8 is bolted to the bottom of the guiding frame 7.

[0037] Specifically, as Figure 1 shown, support legs 9 for supporting the workbench 1 are bolted to the bottom of the workbench 1, and the number of the support legs 9 is four and they are evenly distributed.

[0038] Specifically, as Figure 6 shown, a rectangular groove 10 is formed on the side wall of the workbench 1, and a cleaning brush 11 is slidably connected to the inside of the rectangular groove 10.

[0039] Specifically, as Figure 5 shown, the adjusting assembly 3 includes an adjusting groove 301, a connecting part 302, a lead screw 303, a stabilizing rod 304 and a rotating ring 305.
