[0016] like Figure 1-3 As shown, it includes a motor 1, a fixed disk 2, a wire winding wheel 7, a wire feeding wheel 3, a wire feeding pressure wheel 4 and a pressure wheel mechanism. The wire winding wheel 7 is connected to the fixed disk 2 axis through a screw mechanism. The wire winding wheel 7 is provided with a gear portion and a wire winding groove. The motor 1 is fixed on the fixed disk 2. A wire feeding active gear 6 and a transmission gear 5 are sleeved on the output end of the motor 1. The transmission gear 5 is toothed with the gear portion, and the wire feeding active gear 6 is toothed with the wire feeding wheel 3. The wire feeding wheel 3 is toothed with the wire feeding pressure wheel 4. The pressure wheel mechanism, the wire feeding wheel 3 and the wire feeding pressure wheel 4 are all connected to the fixed disk 2 axis, and the front end of the pressure wheel mechanism is located outside the wire winding groove.

[0017] During implementation, the pressure wheel mechanism, the wire feeding wheel 3 and the wire feeding pressure wheel 4 are all connected to the axis of the fixed disk 2, the wire winding wheel 7 is sleeved on the copper sleeve 18, the rear end of the trapezoidal screw rod 9 is fixed on the fixed disk 2, the copper sleeve 18 is screwed to the trapezoidal screw rod 9, and the pressure wheel mechanism includes a pressure wheel 10, a pressure wheel shaft connecting plate 11, a fixed seat 13 and a lever piece 12. The fixed seat 13 is fixed to the back of the fixed disk 2. The lever piece 12 is connected to the pressure wheel shaft connecting plate 11 through a first cylindrical pin 14. The first cylindrical pin 14 is located in the fixed seat 13. The pressure wheel shaft connecting plate 11 is connected to the pressure wheel 10 through a second cylindrical pin 15. The pressure wheel 10 is located outside the wire winding groove. When feeding wire, the steel wire is wound in the wire winding groove, and the motor 1 drives the wire feeding active gear at the same time. The wheel 6 and the transmission gear 5 rotate forward, the wire feeding active gear 6 drives the wire feeding wheel 3 to rotate, the wire feeding wheel 3 drives the wire feeding pressure wheel 4 to rotate, the transmission gear 5 drives the wire winding wheel 7 to rotate, and the wire winding wheel 7 rotates on the trapezoidal screw rod 9 through the copper sleeve 18. The wire feeding wheel 3 and the wire feeding pressure wheel 4 guide the steel wire so that the steel wire passes through between the wire feeding wheel 3 and the wire feeding pressure wheel 4. During the wire feeding process, the position of the wire feeding pressure wheel 4 is always perpendicular to the position of the wire winding groove, and the front end of the pressure wheel 10 is always located on the outermost steel wire. By setting the pressure wheel 10 on the winding wheel, the pressure degree of the pressure wheel 10 can be adjusted portablely using the lever principle, so that it can press the steel wire with the most appropriate force to prevent the steel wire from loosening on the winding wheel 7. Specifically, the distance between the pressure wheel 10 and the winding wheel 7 can be adjusted by rotating the lever piece 12. By rotating the lever piece 12, the lever piece 12 drives the first cylindrical pin 14 to rotate, and the first cylindrical pin 14 drives the pressure wheel shaft connecting plate 11 to move. The pressure wheel shaft connecting plate 11 adjusts the position of the second cylindrical pin 15. The pressure wheel 10 and the second cylindrical pin 15 run synchronously. The position of the wire feeding pressure wheel 4 can be adjusted by rotating the wire feeding pressure wheel lever 8. Specifically, rotating the wire feeding pressure wheel lever 8 can drive the third cylindrical pin 16 to move. The movement of the third cylindrical pin 16 can change the position of the wire feeding pressure wheel 4. The change in the position of the wire feeding pressure wheel 4 can adjust the guiding direction of the wire. After completing the wire feeding work, the electric When the machine 1 reverses, the one-way wheel does not drive the wire feeding active gear 6 to rotate, and the transmission gear 5 drives the winding wheel 7 to rotate in the opposite direction, and the excess steel wire is reeled back to the winding wheel 7 to save steel wire. The wire feeding wheel 3 acts as a passive mechanism to prevent the winding wheel 7 from tightening the wire quickly, ensuring that the wire on the winding wheel 7 is always in a tightened state during the winding process. When the resistance is too large during the wire feeding process, the wire will bend between the wire feeding wheel 3 and the wire feeding pressure wheel 4. The sensor 19 can sense it and alarm in time to effectively protect the wire from being damaged. When the wire is loose on the winding wheel 7, the sensor 19 senses it and alarms in time to effectively protect the wire from being loose. The sensor 19 can be an infrared sensor or other sensors.
