Abstract

The invention discloses a high-speed optical cable SZ stranding binding machine with a low turnover number, which comprises a stranding binding part. The stranding binding part comprises a first rack, and a stranding device, a winding and binding device and a passive anti-back twisting belt are sequentially arranged on the first rack along an optical fiber sleeve conveying direction; the stranding device comprises a stranding pipe and a positive and negative rotation motor, the stranding pipe is arranged horizontally along the stranding axis of the optical cable, the stranding pipe is connected with the positive and negative rotation motor, the output shaft of the positive and negative rotation motor is also connected with one end of an elastic energy storage device, the other end of the elastic energy storage device is connected with the first rack, and the positive and negative rotation motor drives the stranding pipe to rotate in a positive and negative alternative mode through a stranding synchronous belt. Continuous and automatic SZ stranding and binding for the optical fiber sleeve can be realized, the rotation speed is improved and the SZ stranding turnover number in a unit time is reduced, the stranding quality is improved, the cabling speed is improved, energy is saved, consumption is reduced, and the operation noise is reduced.

Description

technical field [0001] The invention relates to the technical field of optical fiber equipment, in particular to a high-speed optical cable SZ twisting and binding machine with a low turnover number. Background technique [0002] In order to protect the optical fiber transmission performance, the optical fiber must be placed in an optical cable with certain mechanical endurance. The fiber optic cable consists of a bundle tube containing optical fibers, a tensile member and a sheath. Even so, when the optical cable is stressed, the optical cable will be elongated and extended. If the optical fiber in the optical cable does not have a certain excess length, the optical fiber will still be elongated. In order to prevent the optical fiber from being stretched excessively, the bundle tube in the optical cable should be arranged SZ helically. If the bundle tube is placed straight and parallel in the cable, when the cable is stressed, the cable will stretch as much as the bundle ...

Problems solved by technology

The optical fiber bundle tube SZ stranding device is produced under the demand of this optical cable production process. At present, the optical fiber bundle tube SZ stranding device in the market is realized by motor driving and wire rope transmission; the current SZ stranding drive mode, It is difficult for the motor to commutate in the transport mode of frequent forward and reverse operation, especially it is impossible to increase the rotation speed and reduce the number of SZ stranding turnovers per unit time at the same time, which leads to the inability to increase the production speed, especially when the twisting is a one-turn motion process technology Unable to achieve the request
