The cutting groove 18 is fixedly mounted on the inner end of the wire reel 3, so as to automatically cut off the excess wire head when the end of the wire is fixed. The structure is novel and the use is direct and efficient.

[0026] A round rod 14 is fixedly installed at the rear end of the tightening wheel 2, and a nut 15 is threadedly connected to the outer end of the round rod 14. A connecting column 9 is fixedly installed at the front end of the tightening wheel 2. A support frame 10 is rotatably installed at the lower end of the connecting column 9, and the output end of a micro servo motor 12 is fixedly installed at the lower end of the support frame 10. A pressure sensor 13 is arranged on the lower side of the support frame 10, and the pressure sensor 13 is fixedly installed at the left end of the left mounting seat 11, so as to automatically tighten the silk thread, and the tightness can be accurately controlled and is easy to use.

[0027] Specific working principle:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the wire cutting machine is used with the wire threading device, the end of the molybdenum wire is clamped and wound around the lower end of the screw 16 at the right end of the wire drum 3, and the screw 16 is tightened downward to fix the wire. When the screw 16 is tightened downward, the excess wire end is aligned with the lower side of the micro-blade 17. The micro-blade 17 pushes the wire into the inside of the cutting groove 18 for cutting when the screw 16 is tightened downward. After the excess wire is cut off and cleaned, the molybdenum wire is orderly wound around the outer end of the wire drum 3 for cutting. At this time, the tightness of the molybdenum wire is relatively low. When tightening the wire, the tightening wheel 2 is rotated backward so that the upper end of the molybdenum wire is placed on the upper end of the tightening wheel 2, and then the tightening wheel 2 is rotated backward. The tightening wheel 2 drives the connecting column 9 to rotate at the upper end of the support frame 10. The operator rotates the tightening wheel 2 to a straight state at a uniform speed, and then the round rod 14 is clamped to the inside of the bayonet 8, and the nut 15 is tightened. Tighten it to the left to fix the round rod 14. At this time, the first servo motor 5 drives the wire reel 3 to rotate, and the micro servo motor 12 drives the tightening wheel 2 to slowly rotate forward through the support frame 10, and the loose molybdenum wire is tightened by the tightening wheel 2. When the support frame 10 rotates forward, the lower end of the support frame 10 applies pressure to the pressure sensor 13. At this time, the tightness value of the tightening wire can be checked from the upper end of the pressure sensor 13, and the micro servo motor 12 can be selected whether to continue to drive the tightening wheel 2 to continue to increase the rotation angle forward. After the molybdenum wire on the wire reel 3 rotates once, the screw 16 is loosened upwards, the end of the wire is taken out, the excess wire on the tightening wheel 2 is tightened, and the end is re-fixed to complete the tightness adjustment. The above completes a series of operations of the wire threading device for the wire cutting machine. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
