Description

Technical Field

[0001] This utility model belongs to the technical field of wire processing equipment and relates to a wire traction and tensioning mechanism. Background Technology

[0002] During the wire pulling process, due to the difference in winding and unwinding speeds, it is difficult for the wire to maintain a straight and taut state, which is detrimental to the orderly pulling of the wire, the quality of winding, and other processing steps along the pulling path. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a wire traction tensioning mechanism. The technical problem this invention aims to solve is how to tension and buffer the wire traction process.

[0004] The purpose of this utility model can be achieved through the following technical solution: A wire traction tensioning mechanism, characterized in that it includes a ground support, an inlet roller, an outlet roller, an anti-slip roller, and two tensioning rollers. A sleeve is fixedly installed on the ground support, and a sliding rod is slidably connected to each end of the sleeve. The two tensioning rollers are rotatably connected to the outer ends of the two sliding rods, and a pre-tensioning spring located inside the sleeve is connected between the two sliding rods. The anti-slip roller has a spiral wire groove.

[0005] The wire enters from the inlet roller, passes sequentially through the tension roller on the same side as the inlet roller, then winds around the anti-slip roller several times before being pulled to another tension roller, and finally exits from the outlet roller. Due to the presence of the spiral wire groove on the surface of the anti-slip roller, the wire will not slip relative to the anti-slip roller after being wound around multiple times. Therefore, the inlet end and the outlet end can be effectively tensioned or the tension force can be buffered by the two tension rollers respectively. Attached Figure Description

[0006] Figure 1 This is a schematic diagram of the wire traction and tensioning mechanism.

[0007] Figure 2 This is a schematic diagram of the anti-slip roller.

[0008] In the diagram, 1 is the floor support; 2 is the infeed roller; 3 is the outfeed roller; 4 is the anti-slip roller; 5 is the tension roller; 6 is the sleeve; 7 is the slide bar; and 8 is the wire guide groove. Detailed Implementation

[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] like Figure 1 and Figure 2As shown, the wire traction tensioning mechanism includes a floor support 1, an inlet roller 2, an outlet roller 3, an anti-slip roller 4, and two tensioning rollers 5. A sleeve 6 is fixedly installed on the floor support 1. A slide rod 7 is slidably connected to each end of the sleeve 6. The two tensioning rollers 5 are rotatably connected to the outer ends of the two slide rods 7. A pre-tensioning spring located inside the sleeve 6 is connected between the two slide rods 7. The anti-slip roller 4 has a spiral wire groove 8.

[0011] The wire enters from the inlet roller 2, passes sequentially through the tension roller 5 on the same side as the inlet roller 2, and then winds around the anti-slip roller 4 several times before being pulled to another tension roller 5. Finally, it is pulled out from the outlet roller 3. Due to the presence of the spiral wire groove 8 on its surface, the wire will not slip relative to the anti-slip roller 4 after being wound around multiple times. Therefore, the inlet end and the outlet end can be effectively tensioned or the tension force can be buffered by the two tension rollers 5 respectively.

[0012] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
