Description

A twisted wire anti-knot tensioner

technical field

The utility model relates to a tensioner, in particular to a twisted wire anti-knot tensioner.

Background technique

In the production line, a tensioner is usually used to pay off the stranded wire reel. The existing tensioner cannot solve the problem of knotting, loosening and fluffing of the stranded wire. Reduce the quality of finished products; at present, most production enterprises can only rely on manual operation, which is slow in efficiency and unstable in quality. In addition, the existing tensioner uses friction discs or friction plates to generate damping force to generate tension. The tension is uncontrollable during the unwinding process, resulting in unstable tension. In this way, the twisted wire will loosen or turn back, and it is easy to knot and affect production. efficiency.

Utility model content

In order to solve the problems existing in the prior art, the utility model provides an anti-knot tensioner suitable for twisted wires. The tension can be adjusted, which can effectively protect the twisted wires and avoid knotting, which is beneficial to improve production efficiency.

In order to achieve the above object, the technical solution adopted in the utility model is:

An anti-knot tensioner for twisted wires, comprising a positioning rod, a positioning disc, a bearing, a spring and a fixed bushing, the positioning disc is fixed in the middle of the positioning rod, and above the positioning disc, bearings, The spring and the fixed bushing are sleeved on the positioning rod. The fixed bushing is adjusted along the positioning rod by the adjusting mechanism to change the elastic force of the spring. The bearing is connected with a tension rod, and the end of the tension rod away from the bearing is provided with a ceramic hole.

Preferably, the adjusting mechanism is an adjusting bolt arranged on the fixed bushing, and the adjusting bolt passes through a screw hole arranged on the fixed bushing.

Preferably, the adjustment mechanism is a screw connection structure between a fixed bush and a positioning rod.

Preferably, a scale is provided on the side wall of the upper end of the positioning rod, and the moving position of the top end of the fixed bushing is within the range of the scale, and the tension can be adjusted and controlled through the scale to make the quality controllable.

Beneficial effects of the utility model: the tensioner of the utility model adjusts the position of the fixed shaft sleeve through the adjustment mechanism, so that the elastic force of the spring produces resistance to the bearing, so that the resistance received by the tension rod when it rotates is converted into tension, and the tension can be adjusted, and The adjustment is stable and reliable, and the operation is easy and convenient, which can prevent the twisted wire from loosening or turning back, and straighten the twisted wire without knotting; at the same time, the porcelain hole on the tension rod can ensure that the twisted wire will not be scratched Injury, to ensure the reliability of product quality, suitable for stranded wire and enameled wire.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.

Fig. 1 is the overall structural representation of the utility model;

Fig. 2 is a top view of the state of use of the tensioner in the utility model.

detailed description

Referring to Figures 1 and 2, a stranded wire anti-knot tensioner provided by the utility model includes a positioning rod 1, a positioning disc 2, a bearing 3, a spring 4 and a fixed bushing 5, and the positioning disc 2 is fixed on the position of the positioning rod 1. In the middle, above the positioning plate 2, the bearing 3, the spring 4 and the fixed bushing 5 are set on the positioning rod 1 in sequence from bottom to top, and the fixed bushing 5 adjusts its position along the positioning rod 1 through the adjustment mechanism to change the elastic force of the spring 4. The bearing 3 is connected with a tension rod 6, and the end of the tension rod 6 away from the bearing 3 is provided with a porcelain hole 61. Adjust the position of the fixed shaft sleeve 5 through the adjustment mechanism, so that the elastic force of the spring 4 produces resistance to the bearing 3, so that the resistance received by the tension rod 6 when it rotates is converted into tension, so that the tension can be adjusted, and the adjustment is stable and reliable, and the operation is easy and convenient. It can prevent the stranded wire 8 from loosening or turning back, and when the stranded wire 8 is stretched, it will be straightened without knotting.

The above-mentioned adjusting mechanism includes two embodiments. In the first embodiment, the adjusting mechanism is an adjusting bolt 51 arranged on the fixed bushing 5, and the adjusting bolt 51 passes through a screw hole arranged on the fixed bushing 5. When the position of the shaft sleeve 5, loosen the bolt 51, move the fixed shaft sleeve 5 to the designated position and then tighten the bolt 51, the operation is convenient and quick, as shown in Figure 1.

Embodiment 2, the adjustment mechanism is a threaded connection structure between the fixed shaft sleeve 5 and the positioning rod 1, the inner wall of the fixed shaft sleeve 5 is provided with threads, and the outer wall of the corresponding positioning rod 1 is provided with threads, so that the fixed shaft can be adjusted by rotating the fixed shaft sleeve 5 Cover 5 position, the accompanying drawing does not show the structure of embodiment two.

In the above embodiment, a scale is provided on the side wall of the upper end of the positioning rod, and the moving position of the top end of the fixed bushing 5 is within the range of the scale, and the tension can be adjusted corresponding to different scales, which is more convenient for operation and quality control according to the scale.

When in use, the lower end of the positioning rod 1 is inserted into the shaft hole of the reel 7, as shown in Figure 2, wherein the positioning rod 1 is designed according to the standard bobbin specification and has a wide range of applications. The stranded wire 8 passes through the ceramic hole 61, and the tension is adjusted through the fixed shaft sleeve 5 with the scale. When the wire is unwound, the bearing 3 rotates with the direction of the stranded wire 8. The porcelain hole 61 can effectively protect the stranded wire 8 from being scratched and ensure product quality. High reliability, suitable for various types of stranded wires and enameled wires.

The above is only a preferred embodiment of the utility model, and the utility model is not limited to the structure of the above-mentioned embodiment, as long as it achieves the technical effect of the utility model by the same means, it should belong to the protection of the utility model scope.
