However, the current cutting device only has the function of placing the acetate film in the stacking groove, and taking out the acetate film in the stacking groove and placing it on the conveying belt is generally operated by the workers, which is low in efficiency and needs to be stopped for operation. CONTENT OF THE INVENTION

[0006] Further, the tooth grooves penetrate the end faces of the two ends of the upper end plate, the lower end plate away from the pawl is fixedly connected with a convex plate, the workbench on the side away from the groove plate of the material moving port is fixedly connected with a blocking column one, and the blocking column one is used for contacting the convex plate.

[0007] Further, the two side edges of the workbench on the side close to the groove plate of the material moving port are fixedly connected with blocking columns two, and the lower extension strips in the contacting state of the blocking columns two and the convex plate are inserted into the stacking groove.

[0009] Further, the workbench on the side away from the groove plate of the material moving port is provided with a telescopic cylinder two, the telescopic cylinder two is located on the side of the blocking column two away from the material moving port, a pushing plate is fixedly connected to the telescopic rod of the telescopic cylinder two, and the pushing plate is used for pushing the acetate film into the conveying belt.

[0010] The one or more technical solutions provided in the application have at least the following technical effects or advantages:

[0011] Due to the adoption of the clamping mechanism, the acetate film in each stacking groove can be clamped by the clamping mechanism, and then the moving frame is moved to one side of the conveying belt. With the continuous movement of the moving frame, the protruding plates on the outer walls of the lower end plates at both ends of the lower clamping strip will be in contact with the blocking column one. After the contact, the moving frame continues to move, and at this time, the teeth grooves on the upper end plates at both ends of the upper clamping strip will be disengaged from the pawl, and the lower clamping strip will be placed on the tabletop of the workbench. Thus, the clamping mechanism releases the clamping of the acetate film. Then, the push plate is moved by the telescopic cylinder two, so that the push plate pushes the acetate film on the lower clamping strip to move to the conveying belt, thereby solving the technical problem that the acetate film is not automatically moved to the conveying belt in the cutting device in the prior art.
