Stranding machine

Abstract

The invention discloses a stranding machine, comprising an unwinding mechanism, a tension adjusting device, a traction mechanism, a wire-arranging mechanism, a rolling mechanism and a controller, wherein the unwinding mechanism comprises a bracket, a plurality of unwinding rolls and unwinding motors arranged on the bracket; the power output end of each unwinding motor is connected with the respective and corresponding unwinding roll; the traction mechanism comprises a support, a traction disc and a traction motor; and the self speed of the unwinding motors can be adjusted by the controller according to the rotating speed of the traction motor. Compared with the prior art, the stranding machine disclosed by the invention has the advantages that active unwinding is carried out by the unwinding motors, the real-time speed adjustment is carried out on the unwinding motors by combination with the traction motor through the controller, so that the tensions of the front sections and the rear sections of metal wires are constant, certain speed for the stranding and the wire arrangement is maintained, the stranding speed is maintained to be 600-700m / min, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a plying machine, which can be used for plying steel wires, copper wires, etc., and prepares for subsequent weaving. Background technique [0002] Steel wire braided rubber hose is composed of rubber compound and ply steel wire, its quality depends on the quality of ply steel wire besides the compound formula. Plying steel wire generally needs to be woven after plying, and plying machine is a kind of equipment that combines multiple strands of metal wire. The quality of plying steel wire directly affects the quality of rubber hose. [0003] Common plying machines generally include a pay-off mechanism, a wire-arrangement mechanism and a winding mechanism. The pay-off mechanism can output multiple metal wires, the wire-arrangement mechanism can combine metal wires with the same tension into one strand, and the take-up mechanism can combine The wire is wound onto the spool. In order to ensure that the wire tension is the same be...

Problems solved by technology

The plying machine with this structure, in order to maintain constant tension and constant linear speed winding, especially at the beginning and end stages, its plying speed can only be maintained at a maximum of 200-300 m / min, because it is slow when starting and stopping. There is a large impact phenomenon, and after the joint speed exceeds a certain value, the pay-off speed is too fast, which will cause the inconsistency of the wire transmission speed, so that the wire arrangement mechanism will have metal wire accumulation, which is difficult to quickly digest, which will affect the entire joint process.
