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] Different from Embodiment 1, the first tensioning member 3a and the second tensioning member 3b both include tensioning elastic pieces 31 and connecting rings 32, and the third tensioning member 3c includes spring sleeves 33, springs 34 and telescopic connecting rings 35, and the bending strength of the spring 34 at the third tensioning member 3c is equal to the breaking strength of the cable, and the bending strength of the tensioning shrapnel 31 at the second tensioning member 3b and the first tensioning member 3a decreases in turn, which can strengthen the tension Mechanism 3 is flexible to cables, suitable for thicker cables.

[0031] During use, by arranging a supporting table 1 carrying guide wheel 2, tensioning mechanism 3 and cable guide mechanism 4 on the input end side of winding roller 5, and carrying guide wheel 2, tensioning mechanism 3 and cable The guiding mechanism 4 is installed on a "匚"-shaped traction frame 11. Before the cable is rolled up, it needs ...

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] The cable is usually a rope-like cable twisted by several or groups of wires [at least two in each group]. Each group of wires is insulated from each other and is often twisted around a center. The insulating covering layer is mostly erected in the air or installed underground or underwater for telecommunications or power transmission. During the cable processing process, the stretched cable needs to be wound up on the roll, but due to the speed of winding and the unwinding There is a speed difference in the linear speed, so at present, a tensioning device is installed in the winding process to prevent the cable from being broken, but the tensioning force of the existing tensioning device is not sensitive enough, and there is a certain tension in the tensioning device. If the limit is tight, in the...
