Buffering device for producing optical cables

Abstract

The invention discloses a buffering device for producing optical cables. The buffering device comprises a machine frame, sliding blocks, a first guide roller, a second guide roller, first magnetic force blocks and second magnetic force blocks, wherein the machine frame is provided with sliding rails; each sliding block is movably matched with the corresponding sliding rail; the first guide roller is rotatably mounted on the machine frame; the second guide roller is rotatably mounted on the sliding blocks; the first magnetic force blocks are mounted on the machine frame; the second magnetic force blocks are mounted on the second guide roller or the sliding blocks; each first magnetic force block is mutually matched with the corresponding second magnetic force block; and through magnetic force, the second guide roller has movement tendency of being away from the first guide roller. According to the buffering device disclosed by the invention, each sliding block is movably matched with the corresponding sliding rail, and the second guide roller is rotatably mounted on the sliding blocks, so that when the tension of a metal belt is changed, the second guide roller can move, the distance between each first magnetic force block and the corresponding second magnetic force block can also be changed, the magnetic force is changed until the magnetic force and the tension are rebalanced, in the process, the stress of the metal belt is slowly changed, and the occurrence of situations of cracking and the like caused by too large instantaneous stress in the prior art can be effectively avoided.

Description

technical field [0001] The invention relates to optical cable production equipment, in particular to a buffer device for optical cable production. Background technique [0002] The production process of the optical cable sheath includes the step of wrapping the metal tape outside the cable core. When the metal tape is unloaded, it is guided by two parallel guide rollers. In the prior art, the position of the guide roller is fixed. When the tension of the metal tape is unstable , because the guide roller is fixed, the tension on the metal belt cannot be balanced, the metal belt becomes tense and loose with the change of tension, and the moment the metal belt is loosened and then tensioned, the metal belt is easily broken due to excessive force , which will affect the cable production and product quality. Contents of the invention [0003] Aiming at the above problems, the present invention proposes a buffer device for optical cable production. [0004] The technical schem...
