Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a cutting device for printing. Background Art

[0002] During the production and printing process of printed materials, the printed paper needs to be cut into specific required sizes. Currently, the cutting is performed by a paper cutting device, in which a driving mechanism in the cutting device drives the cutting knife to move up and down, thereby separating the paper.

[0003] The utility model with publication number CN216426261U discloses a paper cutting device for printing, which relates to the technical field of cutting equipment, and includes a frame, a No. 1 cylinder and a cutting knife. The No. 1 cylinder is symmetrically arranged on the top of the frame, and the output end of the No. 1 cylinder is connected to the cutting knife. A conveyor belt is arranged at the lower part of the frame, a supporting plate is arranged on the right side of the frame, a collecting box is arranged on the right side of the frame, a flattening mechanism is arranged on the upper part of the frame, and a driving mechanism matching the gear shaft is arranged on the frame.

[0004] However, the above patent has the following shortcomings:

[0005] 1. In the above patent, a flattening mechanism is arranged above the inside of the frame. Before cutting, the No. 2 cylinder in the flattening mechanism drives the roller to move downward to press the paper, and the motor drives the movable plate to move horizontally through the gear shaft and the rack, thereby driving the roller to move horizontally to flatten the surface of the paper, thereby avoiding the wrinkles of the paper itself affecting its cutting quality. However, before cutting, the device only presses and fixes the paper by stopping the roller at the front end of the shearing part. Because the roller can rotate freely and is not limited, it cannot stably fix the paper. Therefore, the paper may slide when the paper is cut, thereby reducing the cutting accuracy of the paper;

[0006] 2. In the above patent, a flattening mechanism is arranged above the inside of the frame. Before cutting, the No. 2 cylinder in the flattening mechanism drives the roller to move downward to press the paper, and the motor drives the movable plate to move horizontally through the gear shaft and the rack, thereby driving the roller to move horizontally to flatten the surface of the paper, thereby avoiding the wrinkles of the paper itself affecting its cutting quality. However, the part of the roller that contacts the paper is the bottom of the circular roller-shaped member, so the actual contact area between the roller and the paper is very small. Therefore, when the roller moves to press the paper, the two sides of the paper may curl, which will lead to a decrease in the flattening quality of the paper. Utility Model Content
