[0072] The working principle of the present invention is as follows:

[0073] like Figure 1-14 As shown, a control system is provided inside the thread binding machine, which controls the corresponding motors of the threading mechanism 1, the knotting mechanism 2, the lifting and hooking mechanism 3, the thread pushing assembly 4, the paper pressing and pulling mechanism 5 and the drilling mechanism 6 to drive the actions of each component;

[0074] First, drive the first lifting motor 505 of the paper pressing and pulling wire mechanism 5 to clamp the file, and control the electromagnetic box 503 to be energized, and the push rod 504 moves to clamp the binding wire in the initial position in the pulling wire clamp 511, so that the lifting hooking wire mechanism 3 can hook it.

[0075] Then the reduction motor 602 of the drilling mechanism 6 is controlled to lift the drilling mechanism 6, and then the drilling motor 608 is driven to move, driving the three drill bits 607 to drill the edge of the file.

[0076] After the drilling is completed, the control system drives the hooking motor 303 of the lifting hooking mechanism 3, and the three hook needles 307 move to pull the binding wire clamped by the wire clamp 511 downward to form a single wire loop.

[0077] Under the action of the first stepper motor 127, the thread loops pulled by the three hook hooks 307 act on the first electric push rod 110 of the threading mechanism 1 with the first thread diverter hook 115, the first "V"-shaped thread pushing piece 116, and the first clamping claw 117, so that the thread loop on the left is pushed by the first "V"-shaped thread pushing piece 116, and the thread loop on the right is pushed by the second "V"-shaped thread pushing piece 108. The first thread diverter hook 115 and the second thread diverter hook 107 open the middle thread loop, and the first "V"-shaped thread pushing piece 116 and the second "V"-shaped thread pushing piece 108 pass the thread loops on the left and right sides through the middle thread loop. Then the first clamping claw 117 and the second clamping claw 109 respectively clamp the thread loops pushed by the second "V"-shaped thread pushing piece 108 and the first "V"-shaped thread pushing piece 116, and then the control system drives the first stepper motor 127 to pull back.

[0078] During the return process, the control system drives the thread-pushing motor 401 of the thread-pushing assembly 4 to work, and the thread-pushing plate 409 presses the through-point of the binding thread.

[0079] After completion, the control system drives the first rotating motor 208 and the second rotating motor 205 to rotate, rotates the left and right thread loops, and tightens the binding line through the first pulling post 202 and the second pulling post 229. At this time, the first knotting hook 228 and the second knotting hook 227 pull the thread loops in opposite directions, and the first pulling post 202 and the second pulling post 229 slowly loosen the thread loops with the movement of the first looping block 210 and the second looping block 207 to complete the tying of the bow.

[0080] To sum up, the present invention uses a lifting and hooking mechanism to cyclically lift up and hook the wire and then lower it to form a structure of three wire loops. The threading mechanism then threads the three wire loops, and the top wire component assists in completing the first knotting. Finally, the knotting mechanism ties a bow on the wire loop for the second time to complete the thread binding and knotting work. This not only achieves the purpose of directly binding the binding materials, but also avoids the problem of binding with the help of tools.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
