[0002] As a thread sealing material, the thread seal wire is widely used in the thread sealing of industrial pipelines, hardware pipelines, engine pipelines and industrial equipment. At present, when winding the thread seal wire at both ends of a metal pipe in the market, manual winding is mainly adopted. Due to the manual winding method, the efficiency is relatively slow, and there are defects of time-consuming and laborious, low efficiency, and the winding quality cannot be guaranteed, and it cannot adapt to continuous operation. Now there appears a semi-automatic thread seal wire winding device, that is, a worker holds the metal pipe by hand, and uses a machine equipped with the thread seal wire to wind around the metal pipe as the center.

[0029] Principle of Thread Sealing Wire Winding

[0030] Manually wind the thread sealing line around the wire guide wheel 806, pass it through the wire blocking pin 807, and then place it on the clamping block 115 of the wire clamping and feeding mechanism 11. Click the wire clamping button on the touch screen 13. After the wire is clamped, the scissors 122 on the wire cutting and feeding mechanism 12 cut off the excess wire end of the thread sealing line. It can be inserted into threaded workpieces or threaded parts 14 of different sizes until it touches the trigger switch 06, triggering the start of the first finger cylinder 503 and the second finger cylinder 504, and the left claw 509 and the right claw 510 clamp the workpiece 14. To accommodate threaded workpieces or threaded parts 14 of different sizes, the wire clamping and feeding mechanism 11 and the wire cutting and feeding mechanism 12 on the first layer of the pallet 103 are adjusted up and down and left and right by the XY-axis moving seat 10 to approach the front end of the workpiece 14. Then, the wire blocking pin 807 rotates to place the thread sealing line on the front end of the workpiece 14, and the first motor 803 is started. The driving gear 802 rotates, driving the rotating gear 801 to rotate. At this time, the thread sealing line rotates and winds around the center of the workpiece 14. At the same time, in order to ensure that the front end of the workpiece 14 is wound within a certain range, the second motor 906 on the synchronization mechanism 09 will, under the guidance of the first lead screw 905, pull back and forth the workpiece fixing clamp mechanism 05 on the telescopic rod 903, so as to ensure that the winding range of the workpiece 14 is more uniform. After the winding is completed, the wire blocking pin 807 pops open, the clamping block 115 on the wire clamping and feeding mechanism 11 clamps the wire, and the scissors 122 are extended and pressed down by the cutting cylinder 123 to cut the wire back and forth. Finally, the first finger cylinder 503 and the second finger cylinder 504 are reset, and the left claw 509 and the right claw 510 release the wound workpiece 14.

[0031] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model.
