Description

Technical Field

[0001] The utility model relates to the field of thread-bound book binding, in particular to a thread-bound book punching device. Background Art

[0002] Thread-bound books are a traditional way of book binding, which is characterized by punching holes at specific positions on the book paper and then stringing the paper together with thread. After the staff has arranged the paper to form a book, they place the book on the workbench of the punching machine, align the edge of the book where the holes are to be punched with the position of the punching needle, and then perform the punching operation. Existing punching machines generally use a cylinder to drive multiple punching needles to move downward for punching, wherein the punching needles are cylindrical needles. During the punching process, the cylindrical surface of the punching needle will cause increased friction between the paper and the needle when punching. During the upward movement of the punching needle, the friction will cause tiny tears or burrs on the edge of the paper, affecting the threading and binding of the book in the later stage. In order to solve this problem, a new type of thread-bound book punching device is needed. Utility Model Content
