[0002] During the production and processing of wire, a traction mechanism is required to pull and reel the wire. When the wire is spit out in the processing equipment, the traction equipment pulls the wire and authorizes the wire. Currently, the traction equipment is mainly composed of a traction roller and a supporting part of the traction roller. The traction roller reels and pulls the wire. After the wire is rewound, it needs to be removed from the traction roller. However, the contact area between the rolled wire and the traction roller is large, and the extrusion pressure of the wire on the traction roller is also large. It is more troublesome to remove the rolled wire from the traction roller, especially the wire in contact with the traction roller, the surface of which is easily damaged.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a technical solution:

[0024] See also Figure 1-8 A traction mechanism that can reduce damage, wherein the surface of the traction roller 5 has a plurality of semicircular grooves 51, and a round rod 9 slides in the semicircular groove 51. The initial end of the wire is wound around the outside of the traction roller 5, and the servo motor 31 is started. The servo motor 31 drives the traction roller 5 to rotate through the sprocket 1 31, the chain 34, the sprocket 2 33 and the shaft 4. At this time, the wire begins to be wound around the outside of the plurality of round rods 9. When the wound wire is sufficient, the servo motor 31 is turned off, the screw 11 is unscrewed, and the wire is wound outward. Pull the wire resistance drum 2 10, and at this time, several round rods 9 drive the wound wire to separate from the traction roller 5, until the round rods 9 completely slide out from the traction roller 5, and the wound wire is also separated from the outside of the traction roller 5. Since the round rods 9 can slide on the wire resistance drum 2 10 using the sliders 13 and the slide grooves 12, that is, several round rods 9 can be close to each other, when the wound wire is removed, there will be no conflict with the wire, and the wound wire can be quickly removed from the several round rods 9 without damage.

[0025] Among them, when the round rod 9 is in the semicircular groove 51, the round rod 9 is convex relative to the outer surface of the traction roller 5, so that the wire will not contact the traction roller 5 during winding, and when the round rod 9 is in a convex state relative to the outer surface of the traction roller 5, the slider 13 is at the top of the slide groove 12, and when the slider 13 is at the bottom of the slide groove 12, the upper end surface of the round rod 9 is flush with the bottom of the semicircular groove 51, and the round rod 9 has a cutout 8 at one end facing the traction roller 5, so that the range of movement of the round rod 9 is limited each time. Even if the round rods 9 slide to the closest state, the cross-section of the cutout 8 of the round rod 9 will still contact the entrance part of the semicircular groove 51. In this way, only the wire resistance disk 10 needs to be pushed, and the round rod 9 can automatically enter the semicircular groove 51, and there is always a round rod 9 that does not move. This immovable round rod 9 is always kept at the top, so that when the wound wire is removed, the round rod 9 can support the wire.

[0026] In the above, the wire resistance disk 10 is composed of two sub-disks 101, and the slide groove 12 is located on the sub-disk 101 adjacent to the traction roller 5. The two sub-disks 101 are fixed by screws, and the purpose is to install the slider 13 into the slide groove 12.

[0027] In addition, the upper part of the support frame 1 is a disc-shaped structure, and the upper part of the support frame 1 is provided with a limiting support ring 7 on one side facing the wire resistance drum 2, and a bearing 6 is installed inside the limiting support ring 7. The wire resistance drum 2 is in the bearing 6. During the traction process, the limiting support ring 7 can be used to provide additional support to the traction roller 5.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
