Description

TECHNICAL FIELD

[0001] The utility model belongs to printing equipment technical field relates to a kind of sewing book cutting and pressing machine. BACKGROUND

[0002] The processing mode of the sewing book is to cut and stack the paper, and then bind it by sewing. After sewing, the book is cut into small books, and the binding thread is cut off at the same time.

[0003] The disadvantage of this sewing book is that after the thread is cut off, there will be two exposed thread ends at both ends of the book. If these two thread ends are not treated, the thin book may come off the thread when the thread end is accidentally pulled due to its excessive length, affecting use.

[0004] In view of the above situation, if the thread end is too long after sewing, the worker needs to cut it short first, and then use a hot air gun to blow the thread end at both ends of the book. After being heated, the thread end will melt and shrink into a spherical shape. After cooling, the spherical shape becomes hard, which can lock the thread end and prevent it from coming off. However, all these operations need to be done manually by the worker, which is time-consuming and labor-intensive. Moreover, the worker needs to press and cut the thread end one book at a time, which is very low in work efficiency. UTILITY MODEL CONTENTS
