Description

Technical Field

[0001] The utility model relates to the technical field of printing and binding, in particular to a punching device for printing and binding of printed matter. Background Art

[0002] Many printed papers are bound by punching holes in iron rings, so a punching device is needed.

[0003] Chinese patent publication number CN218083049U proposes a "punching device for printing and binding". The technical solution proposes the problem that "in order to prevent the scattering of paper scraps from punching, the current punching device will change the working surface of the punching device into a screen plate, and the debris will naturally fall through the screen plate, but it is difficult to avoid that a small amount of paper scraps will remain on the screen plate." The utility model provides the following technical solution: "It includes a workbench, the top of the workbench is provided with a bracket, the bracket is provided with a punching mechanism, the top wall of the workbench is provided with a through hole, the inner cavity of the workbench is provided with an orifice intermittent blocker, the punching mechanism is provided with a puncher, the through hole is located directly below the puncher, and in the initial state, the top end of the orifice intermittent blocker blocks the through hole to prevent other impurities from entering the inner cavity of the workbench. When the puncher moves down to punch the paper placed on the workbench, the punched paper scraps are driven by the puncher to move down into the orifice, and push the orifice intermittent blocker to move down away from the through hole, so as to achieve the purpose of the paper scraps falling smoothly into the inner cavity of the workbench."

[0004] The above scheme has the following defects: when using the above device, the paper needs to be placed directly on the bottom of the cylindrical knife, and then the telescopic rod pushes the cylindrical knife down to punch holes in the paper. If the worker makes an operating error or a mechanical failure occurs later, the cylindrical knife will drop when placing the paper and directly punch holes in the worker's hand. Therefore, a punching device for printing and binding of printed materials is proposed to solve the above problem. Utility Model Content
