Mechanical concentric stranding unwinding tension control system

Abstract

The invention discloses a mechanical concentric stranding unwinding tension control system. The mechanical concentric stranding unwinding tension control system can overcome the defects that an existing method for the tension control of the concentric stranding is mainly used for carrying out tension release or compensation by manually controlling the rotating speed driven by the concentric stranding or winding and unwinding, which is low in precision and is extremely inconvenient, the tension cannot be quickly adjusted, and the efficiency is low. The system comprises a main shaft, a wire storage reel arranged on the main shaft and a flying-wing system located on one side of the main shaft, wherein the bottom of one end of the flying-wing system is connected with a lower connecting rod, awire passing guide wheel is arranged at the bottom of the lower connecting rod, an extruding shaft is arranged at the top of one end of the flying-wing system, a second moving shaft penetrates throughthe middle of the extruding shaft, a torque joint is wound on the extrusion shaft, a movable rod is connected to the flying-wing system, a third movable shaft is connected to the bottom end of the movable rod in a penetrating mode, the side wall of the movable rod is provided with an end, and the end is connected with a first movable shaft in a penetrating mode.

Description

technical field [0001] The invention relates to the field of concentric strand pay-off, in particular to a mechanical concentric strand pay-off tension control system. Background technique [0002] In the process of taking up and paying off the concentric twisted wire, it is easy to cause the wire to break due to excessive tension or cause disorder when the tension is too small. Therefore, the concentric twisted wire needs to be controlled during operation. Some tension control methods used for concentric stranding often release or compensate the tension by artificially controlling the rotational speed of the concentric stranding or the take-up and pay-off line drive. Manual control is not only inaccurate, but also extremely inconvenient, and it cannot be done. The adjustment of tension is realized quickly, and the efficiency is low. [0003] The Chinese patent with the publication number CN105984752A discloses a concentric stranding machine and its tension control device. ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a mechanical concentric twist pay-off tension control system, which can solve the problem that the existing tension control method for concentric twist often releases tension by artificially controlling the rotational speed of the concentric twist or take-up and pay-off drive. Or compensation, artificial control is not only low in accuracy, but also extremely inconvenient, and can not quickly achieve tension adjustment, the defect of low efficiency
