The pressure strip 2 is connected to the wire clamping drive device, and the wire clamping drive device is fixed to the connecting plate 3; the down-pressing tube 1 is fixed to the connecting plate 3, and the connecting plate 3 is fixed to the wire pulling drive device.

[0021] The wire clamping drive device includes a connecting block 6, a stud 8, a fixed ear plate 7, a spring and an electromagnet 11. The connecting block 6 is connected to the pressure strip 2, and the connecting block 6 is installed with a stud 8. The connecting plate 3 is provided with a fixed ear plate 7. The fixed ear plate 7 and the down-pressure tube 1 are respectively located on both sides of the connecting plate 3. The connecting plate 3 is provided with a through hole 12. The connecting block 6 is installed in the through hole 12. The fixed ear plate 7 is provided with a through hole. The stud 8 is installed in the through hole. A spring is set on the stud part between the connecting block 6 and the fixed ear plate 7. The two ends of the spring are respectively in contact with the connecting block 6 and the fixed ear plate 7. A stud cone 9 is provided on the top of the stud 8. The stud cone 9 is made of iron. An electromagnet 11 is provided on the corresponding position of the downlink frame. The electromagnet 11 is magnetically adsorbable and detachable from the stud cone 9.

[0022] The wire pulling drive device includes a slider 4, a slide rail 10 and a synchronous belt mounting clamp 5, the slider 4 is installed on the slide rail 10, the slide rail 10 is installed in the downlink frame 13, and the slider 4 is fixed to the connecting plate 3; the connecting plate 3 is fixedly connected to the synchronous belt mounting clamp 5, the synchronous belt mounting clamp 5 includes a synchronous belt clip 51, a pressure plate pad 52 and an elastic pressure plate 53, the synchronous belt clip 51 is connected to the pressure plate pad 52, the pressure plate pad 52 is connected to the elastic pressure plate 53, a clamping groove is formed between the synchronous belt clip 51 and the elastic pressure plate 53, the synchronous belt clip 51 is fixedly connected to the connecting plate 3, a synchronous belt is provided in the clamping groove, and the synchronous belt is driven by the wire pulling motor installed on the downlink frame.

[0023] Working principle: Before the cutting wire reaches the groove at the bottom right end of the bead 2, the electromagnet 11 is powered on and started. The electromagnet 11 attracts the stud cone 9 to move upward, and the stud 8 drives the connecting block 6 and the bead 2 to move upward. The spring is compressed and stores energy at this time, and the diameter of the wire between the groove of the bead 2 and the lower pressure tube 1 is expanded. When the cutting wire is fed between the lower pressure tube 1 and the bead 2 and passes through the tail end of the lower pressure tube 1 and the bead 2, the electromagnet 11 is powered off and demagnetized, and the spring releases energy to restore its original state. The connecting block 6 drives the bead 2 to clamp the wire downward, and the stud 8 and the stud cone 9 move downward. The stud cone 9 and the electromagnet 11 are in a separated state. Then, the wire drawing motor drives the synchronous belt to move, the synchronous belt drives the synchronous belt mounting clamp 5 to move, the synchronous belt mounting clamp 5 drives the connecting plate 3 to move, and the connecting plate 3 drives the cutting wire between the lower pressure tube 1 and the bead 2 to move forward, realizing the wire drawing operation. At this time, the stud cone 9 and the electromagnet 11 are separated from the corresponding positions. When the next wire threading operation is performed, the synchronous belt moves in the opposite direction. At this time, there is no wire between the lower pressure tube 1 and the pressure strip 2. The lower pressure tube 1 and the pressure strip 2 are sent back to the original wire connection position. At this time, the electromagnet 11 and the stud cone 9 return to the corresponding positions. Example 2

[0027] Working principle: The wire drawing motor drives the synchronous belt to move, the synchronous belt drives the synchronous belt mounting clamp 5 to move, the synchronous belt mounting clamp 5 drives the connecting plate 3 to move, and the connecting plate 3 drives the cutting wire between the lower pressure tube 1 and the pressure strip 2 to move forward to realize the wire drawing operation; when the cutting wire tightly clamped between the lower pressure tube 1 and the pressure strip 2 reaches the specified position of the wire-binding drum, the wire-clamping electric lead screw assembly and the bottom of the connecting block 6 are changed from the dislocated separation state to the corresponding position separation state or the corresponding position contact state, and the wire-clamping electric lead screw assembly is started to lift the connecting block 6 upward. At this time, the spring is compressed and energy is stored, the pressure strip 2 is lifted upward, and the cutting wire is tied to the wire of the wire-binding drum.
