[0002] A binding machine is a special mechanical equipment for enterprises and institutions to bind various paper materials such as documents, account books, ledgers, and bills. In the work of file management, file binding is an important link. The initial manual wire binding method is to use a wire awl to punch small holes and then use a crochet hook to pick up the binding wire one by one, and finally tie a knot manually for binding. During the binding process, it is necessary to forcefully pierce through the binding object, which is not only time-consuming but also labor-intensive and inefficient, and there are also significant limitations on the binding thickness. The binding machine has well solved this problem. However, the binding machines of the existing technologies, although they can achieve automatic hole punching and wire hooking, can only punch one hole and hook the wire once at a time, and the operation is still relatively troublesome and the efficiency is still low.

[0074] The paper pressing process of the described text fixing device is as follows: First, place the paper on the platen 2, and then press down the paper pressing plate 5-1. The downward movement of the paper pressing plate 5-1 drives the locking shaft 5-2 to move downward together. During the downward movement of the locking shaft 5-2, the locking shaft 5-2 can be clamped under the action of the inclined surface of the locking part 5-302. After the paper pressing plate 5-1 presses the paper, it can play a role in fixing the paper. After punching and threading are completed, press the button (i.e., the end of the driving member 5-4). The downward movement of the driving member 5-4 can push the locking member 5-3 to rotate, making the locking part 5-302 gradually tend to be horizontal. At this time, the clamping force between the locking part 5-302 and the locking shaft 5-2 also gradually disappears.

When the platen 2 is in the first position, at a position corresponding to the thread hooking groove 4-101 on the platen 2, there is a wire feeding groove 203, and the wire feeding groove 203 is communicated with the thread hooking groove 4-101. The cotton thread can be stuck in the thread hooking groove 4-101 through the wire feeding groove 203. One end of the platen 2 close to the punching device is provided with an avoidance groove 204. When the platen 2 is in the second position, the thread hooking needle 6-5 can pass through the through holes on the bracket and the fixed plate 4-1, and then pass through the avoidance groove 204 at the end of the platen 2 to hook up the thread in the thread hooking groove 4-101 to achieve thread hooking.

The three thread-hooking needles 6-5 are arranged in sequence along the length direction of the upper surface of the sliding block 6.

[0077] The described transmission mechanism includes a fixed rack 6-6, a movable rack 6-7 and a gear 11. In this specific embodiment, there are two sets of the fixed rack 6-6, the movable rack 6-7 and the gear 11. The fixed shaft 6-2 is a square shaft, and the middle part of the gear 11 is provided with a square hole 6-801 matching the square shaft. The two gears 11 are both sleeved outside the square shaft. Long holes 101 are provided on both side walls of the frame 1, and the long holes 101 are arranged longitudinally. The fixed shaft 6-2 and the gear 11 are installed in the frame 1. The two ends of the fixed shaft 6-2 respectively pass through the long holes 101 on both side walls of the frame 1 and are exposed outside the long holes 101. Limit pieces 6-9 are provided at both ends of the fixed shaft 6-2, and the limit pieces 6-9 on both sides limit the fixed shaft 6-2 on the frame 1. The handle 6-1 is installed on the end of the fixed shaft 6-2 exposed outside the side wall of the frame 1.

The two fixed racks 6-6 and the two movable racks 6-7 are respectively correspondingly meshed with the two gears 11.

[0078] A first through hole for the thread-hooking needle 6-5 to pass through is provided on the upper side of the frame 1. An avoidance groove is provided on the table board 2, and a second through hole for the thread-hooking needle 6-5 to pass through is provided on the pressing paper board 5-1.

[0079] Rotate the handle 6-1, and the handle 6-1 can drive the fixed shaft 6-2 to rotate, thereby driving the gear 11 to rotate; the gear 11 can drive the movable rack 6-7 to move up and down, and the rotation of the gear 11 is also affected by the fixed rack 6-6, so the gear 11 can also move up and down; the movable rack 6-7 can drive the slider 6 to move up and down. When the slider 6 moves upward, the thread-hooking needle 6-5 can pass through the first through-hole, the clearance groove and the second through-hole and then be exposed outside the pressing plate 5-1.

[0080] The working process of the wire binding machine of the present invention is as follows: At the initial position, the table board is located at the punching position, that is, the limit pin is stuck in the first clamping position. Put the cotton thread into the wire-releasing groove and clamp it in the wire-hooking groove of the fixing plate; then place the paper on the table board; then press down the pressing plate, and the downward movement of the pressing plate drives the locking shaft to move downward together until the pressing plate presses the paper on the table board, and the locking member clamps the locking shaft. Then rotate the punching handle, and the punching knife moves downward to punch the paper, and the waste paper punched out remains in the through-hole of the punching knife. After the paper punching is completed, pull the table board, and the lower end of the hemispherical body of the limit pin will come out of the first clamping position and slide on the wall of the frame. After sliding for a certain distance, it will be stuck in the second clamping position. Then rotate the handle, and the rotation of the handle can drive the thread-hooking needle to move upward. After the thread-hooking needle passes through the through-holes on the bracket and the fixing plate, and then passes through the wire-hooking groove on the fixing plate and the clearance groove on the table board, the thread in the wire-hooking groove can be hooked up, and then the cotton thread can be manually knotted. After the knotting is completed, press the button (i.e., the end of the driving member), and the downward movement of the driving member can push the locking member to rotate, so that the locking part gradually tends to be horizontal. At this time, the clamping force between the locking part and the locking shaft also gradually disappears. When the clamping force is less than the elasticity of the return elastic member, the return elastic member can automatically rebound to lift the pressing plate automatically, and the operation is very convenient.
