Automatic book thread stitching system

Abstract

The invention discloses an automatic book thread stitching system. A machine needle of a machine needle system is connected with a crank-link mechanism. The crank-link mechanism is connected with a driving shaft of a transmission system through a synchronous belt wheel a and a synchronous belt wheel b. A coil stitching system is connected with the driving shaft of the transmission system through a gear d. A book moving system is connected with the coil stitching system through a gear e. The book moving system is provided with an incomplete tooth gear and a flat groove cylinder cam. The incomplete tooth gear is engaged with a rack of a movable platform. The flat groove cylinder cam is connected with a push rod of the movable platform. The rack is controlled to intermittently linearly move front and back through the incomplete tooth gear, and longitudinal intermittent linear movement of a book on the movable platform is achieved. The push rod is controlled by the flat groove cylinder cam to intermittently transversely move left and right, and intermittent reciprocating transverse movement of the movable platform and the book is achieved. The phenomenon of sheet scattering of the book is avoided, bookbinding is firm, errors are small, punching is perpendicular, bookbinding is tidy, and thread-bound book bookbinding can be automatically finished; and efficiency is improved, and the book yield is high.

Description

technical field [0001] The invention belongs to the technical field of book binding equipment, and in particular relates to an automatic thread binding system for books. Background technique [0002] As one of the symbols of ancient Chinese civilization, the thread-bound book has evolved into a symbol of cultural and artistic value with its simple appearance, profound connotation, and elegant artistic conception, showing the elegance and strength of Chinese classical civilization. At the same time, thread-bound books are easy to read and not easy to break, especially suitable for repeated reading and long-term storage. Therefore, thread-bound books and their form are deeply loved by publishing houses, archives, note preservation, readers and book collectors. [0003] Punching and thread binding are the main features of thread-bound books. As a model of traditional Chinese book design, thread-bound books have profoundly influenced the development history of Chinese book bind...

AI Technical Summary

Problems solved by technology

Most of the existing binding machines use hand-press binding, which is difficult to punch holes at one time when binding thick books, that is, it is difficult to bind thick booklets. Metal nails are prone to rust, break and loose pages

Therefore, the stapler can only bind books that are thin and used for a short time. Most of the books with a large number of pages are still bound in glue, but the glue used for glue-bound books is prone to aging due to long-term use, or the books are easily damaged by inappropriate external forces. Phenomena such as glue opening and page loosening occur

However, the usual manual punching and then manual binding will lead to production efficiency due to the independence of punching and binding, and there will be large errors in manual production. The most common is uneven drilling and loose binding, which often leads to irregular binding. If the hole is not vertical, the book will be distorted, making it difficult to guarantee the quality of the thread-bound book

Aiming at the time-consuming, labor-intensive and inefficient technical problems of manual binding or glue binding with ordinary staplers in the prior art for large-scale book binding, how to develop a new type of book automatic thread binding system has important practical significance
