Description

Technical Field

[0001] The invention relates to the field of machinery, and in particular to a thread binding machine. Background Art

[0002] The management of paper materials such as archives and financial vouchers is an essential task in all enterprises and institutions, and binding paper materials is a way to facilitate sorting and searching. Binding generally includes plastic hoses, thread seams, nails, drilling and threading, etc. Among them, the method of stacking paper materials neatly, drilling holes and threading is the most in line with the specifications of archive management. It can be stored for a long time, has a firm connection, and can adapt to the management of paper archives of various thicknesses and materials.

[0003] After punching holes, traditional threading and binding machines generally still choose to thread manually or use a threader to hook the binding thread and then bind it. Using manual threading not only requires more labor, but also has low threading efficiency. The existing method of hooking the thread and then binding with a threader has the following technical problems:

[0004] 1. The mechanism components for driving the threading needle are relatively complicated and often prone to failure during actual use; or the punching motor is directly used for driving, which makes the threading needle's stroke stability insufficient.

[0005] 2. Only manual or electric starting can be used. Manual starting requires high-intensity manual labor, while electric starting cannot be used in a power outage, and the two driving modes cannot be perfectly combined.

[0006] 3. The current technology can only separate the two steps of drilling and wire binding. First, the paper materials are drilled on the drilling machine, and then the paper materials with completed holes are moved to the threader for threading and binding. It requires a lot of manual labor for handling and the cost of equipment is relatively high. Summary of the invention

[0007] In order to solve the technical problems of the existing threading binding machine with complicated components and insufficient stability, the present invention provides a thread binding machine:
