Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a traction mechanism for cable processing, which solves the problem that the tension force of the existing tensioning device is not sensitive enough, and there is a certain tension limit in the tensioning device. In the state, the cable will still be broken, interrupting production and affecting the production speed.

Embodiment 2

[0030] The difference from Embodiment 1 is that the first tension member 3a and the second tension member 3b each include a tension spring 31 and a connecting ring 32, and the third tension member 3c includes a spring sleeve 33, a spring 34, and a telescopic connecting ring. 35, and the bending force of the spring 34 at the third tensioning member 3c is equal to the cable breaking force, the bending force of the tensioning elastic piece 31 at the second tensioning member 3b and the first tensioning member 3a is sequentially reduced, which can increase the tension The elasticity of the 3 pairs of cables is suitable for thicker cables.

[0031] When in use, a supporting table 1 carrying the guide wheel 2, the tensioning mechanism 3 and the cable guide mechanism 4 is arranged on the input end side of the winding roller 5, and the carrying guide wheel 2, the tensioning mechanism 3 and the cable The guiding mechanisms 4 are all installed on a "dang"-shaped traction frame 11. The cable...

Abstract

The invention discloses a traction mechanism for cable processing. The traction mechanism comprises a winding roller used for winding a cable and a traction motor used for driving the winding roller to rotate, wherein one side of the input end of the winding roller is provided with a supporting table, a traction frame is fixedly mounted on the top of the supporting table, a guiding wheel and a tensioning mechanism which are used for tensioning the cable are mounted on the inner side of the traction frame, and one end of the tensioning mechanism is rotationally connected with the guiding wheel.The tensioning mechanism correspondingly comprises a third tensioning piece, a second tensioning piece, and a first tensioning piece, elastic force of the third tensioning piece, elastic force of thesecond tensioning piece and elastic force of the first tensioning piece are sequentially reduced in the conveying direction of the cable, when speed difference appears during cable winding, and the pulling condition of the cable is generated, the first tensioning piece which is closest to the winding roller and has the smallest elastic force firstly can contract, and then the second tensioning piece and the first tensioning piece can sequentially contract so as to increase the buffering distance of the cable, so that the reaction of the tensioning mechanism is more sensitive, and the tensionchange to the cable is relieved.

Description

Technical field [0001] The invention relates to the technical field of cable processing, in particular to a traction mechanism for cable processing. Background technique [0002] A cable is usually a rope-like cable formed by twisting several or several groups of wires [each group of at least two wires]. Each group of wires are insulated from each other and often twisted around a center. The entire outer bread has a height Insulating coatings are mostly erected in the air or installed underground or underwater for telecommunications or power transmission. During the cable processing, the stretched cable needs to be wound on a roll, but due to the winding speed and release There is a speed difference between the line speed, so the tensioning device is currently installed in the winding process to prevent the cable from breaking, but the existing tensioning device is not sensitive enough, and the tensioning device cannot be tensioned to a certain extent. Tightening the limit, in t...
