Pay-off device of tubular strander

Abstract

Provided in the invention is a pay-off device of a tubular strander. With the pay-off device, a wire breaking phenomenon can be avoided. The pay-off device comprises a pay-off cradle support, a pay-off plate, and an auxiliary guiding device. To be specific, the pay-off cradle support in a frame shape has a front wall, a rear wall, two side walls that are arranged at the two sides of the front wall and the rear wall and connect the front wall and the rear wall together; and a wire through hole is formed in the front wall. The pay-off plate includes a winding shaft wound with a lead and baffle plates arranged at the two sides of the winding shaft; and the pay-off plate is erected on the two side walls of the pay-off cradle support in a rotating mode. The auxiliary guiding device includes a guide roller support arranged at the rear wall of the pay-off cradle support vertically and a guide roller; the two ends of the guide roller are supported by the guide roller support and the guide roller can rotate freely; and the axial direction of the guide roller is identical with that of the winding shaft of the pay-off plate. A lead extends into the wire through hole by the guide roller from the pay-off plate.

Description

technical field [0001] The invention relates to a pay-off device of a pipe stranding machine. Background technique [0002] At present, in the power transmission and transformation projects of the State Grid, cables and the like are usually composed of twisted wires, which are formed by transposing a single wire. When making such twisted wires, a tubular stranding machine is usually used. The tube stranding machine can transpose copper wire, aluminum wire or steel wire to form stranded wire. [0003] A pay-off device is provided at the input end of such a pipe strander, which transports the wires wound on the pay-off reel to the pipe strander. The pay-off device is composed of a pay-off cradle bracket and a pay-off reel. Threading holes are formed on the front wall of the cradle, and the pay-off reel can be rotatably erected on the two side walls of the pay-off cradle support. [0004] When using such a pay-off device, the wire wound on the pay-off reel is wound from the r...

Problems solved by technology

[0005] However, in the case of using such a pay-off reel, when the wire is paid out to both sides of the pay-off reel, if the wire is pressed by the lower layer wire, the angle of intersection between the lower layer wire and the wire to be released is large, The pressing point is one point, and the pressing force is concentrated on one point, so it is easy to cause the wire of the wire to break. At this time, the wire must be stopped and welded to continue production. The welding work consumes a lot of man-hours and makes the overall production of the pipe stranding machine difficult. Efficiency becomes worse
