Description
Technical Field
[0001] The utility model belongs to the technical field of strand twisting machines, and particularly relates to a wire jumping prevention device for strand twisting machines. Background Art
[0002] A stranding machine is a machine that twists several metal wires into strands according to a certain lay pitch and lay direction. A single wire is a wire and multiple wires are strands. Generally, wire ropes use round-end carbon steel wires with a diameter of 0.1-6.00mm. As the variety of wire ropes continues to increase, the structure is becoming increasingly complex. In addition to various coated steel wires, stainless steel wires and bimetallic steel wires are also used.
[0003] At present, the stranding machine needs to be used in conjunction with a winding wheel. There is a problem of wire breakage when the winding wheel rotates, which causes wire skipping, affecting production and safety.
[0004] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it is revised and improved. At the same time, in the spirit and concept of seeking for excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model is created, and a wire jumping prevention device for a stranding machine is provided to solve the above problems. Utility Model Content

[0008] As a preferred embodiment of an anti-wire jumping device for a stranding machine, the bottom thread of the support frame is equipped with a rod body, and the bottom of the rod body is provided with a support arm for supporting the winding wheel, which is beneficial to improving the stability of the winding wheel.
[0009] As a preferred embodiment of an anti-wire jumping device for a stranding machine, a right-angle piece is provided at one end of the anti-wire jumping mechanism, and the anti-wire jumping mechanism is fixedly matched with a support frame through the right-angle piece, and the right-angle piece is used to achieve the stability of the anti-wire jumping mechanism.
[0010] As a preferred embodiment of an anti-wire jumping device for a stranding machine, the anti-wire jumping mechanism includes a right-angle frame, which is composed of a transverse body and a longitudinal body. A linear electric cylinder is provided at one end of the transverse body, and a ring is provided at the bottom of the longitudinal body, which is slidably fitted on the shaft.
[0011] As a preferred embodiment of the anti-wire jumping device for a stranding machine, the thread on the shaft is matched with a limiting ring, and the ring is located between the winding wheel and the limiting ring.
[0012] By adopting the above scheme, the limiting ring is used to limit the ring, and cooperates with the right-angle piece to improve the stability of the anti-wire jumping mechanism. Under the action of the right-angle piece, the anti-wire jumping mechanism does not rotate with the winding wheel to ensure stable guidance of the wire twist.

[0015] As a preferred embodiment of the anti-wire jumping device for a stranding machine, the end surface of the brake block is provided with convex teeth.
[0016] With the above solution, the movement of the output end of the linear electric cylinder will brake the wire twist through the brake block, and the convex teeth can improve the stability of the braking.
[0017] The linear electric cylinder needs to be used synchronously with the front-end tension sensor. Broken wire will affect the change of the resistance value of the tension sensor. At this time, the linkage action of the linear electric cylinder will brake the wire twist.
[0018] After adopting the above technical scheme, the beneficial effect of the utility model is: the anti-wire jumping mechanism of the device does not rotate with the winding wheel to ensure the stable guidance of the wire twist.
