Description

Technical Field

[0001] The utility model relates to the technical field of film cutting equipment, in particular to a film cutting device for rust-proof film. Background Technique

[0002] The rust-proof film, namely the gas-phase rust-proof plastic film, is a product based on the combination of polymer materials and VCI gas-phase rust-proof technology. This film can tightly wrap metal articles and form a protective film by releasing rust-proof gas factors, effectively isolating the factors that induce rust in the outside world, thereby preventing metal articles from rusting. In practical applications, due to the different sizes of metal products, precise cutting of the rust-proof film is required.

[0003] The published patent No. CN214394306 discloses a film cutting device for uniform film cutting. The first motor drives the turntable to rotate. The turntable drives the toggle plate to reciprocate up and down through the deflection plate. The toggle plate drives the toggle wheel to rotate intermittently. The toggle wheel drives the cross roller to rotate. The cross roller drives the conveyor belt to move intermittently. At the same time, the second motor drives the crankshaft to rotate. The crankshaft drives the cutter to reciprocate up and down through the rotating rod. When the conveyor belt stops moving, the cutter can cut the film. When the cutter rises, the conveyor belt drives the film to move, so that the film can be cut evenly, and the cutting effect is better. However, the following problems still exist in the actual use of this patent:
