Wire paying-off machine

Abstract

The invention discloses a wire paying-off machine comprising a rack, a winding shaft assembly, a supporting rod, a sliding rod, a sliding block, a mounting block and a wire passing cylinder. The winding shaft assembly and the supporting rod are arranged on the rack, the sliding rod is fixedly connected with the supporting rod, the sliding block is slidably connected with the sliding rod, the mounting block is connected with the sliding block, a connecting through hole is formed in the mounting block, the axis of the connecting through hole is perpendicular to the plane where the supporting rodand the sliding rod are located, and the wire passing cylinder is mounted in the connecting through hole in a sleeved mode; the wire passing cylinder comprises an outer layer cylinder body, an innerlayer cylinder body, a roller and a cover ring; and the inner layer cylinder body is sleeved with the outer layer cylinder body, the roller is arranged between the outer layer cylinder body and the inner layer cylinder body, the roller is protruded out of the inner wall of the inner layer cylinder body, the roller can rotate relative to the outer layer cylinder body and the inner layer cylinder body, and the cover ring is fixedly connected with the end faces of the inner layer cylinder body and the outer layer cylinder body. According to the wire paying-off machine, the pressure between a wireor a cable and the wire passing cylinder is dispersed by sliding of the sliding block on the sliding rod and rotating of the roller, thus dynamic friction between the wire or the cable and the wire passing cylinder is lowered, and then abrasion of the wire or the cable is reduced.

Description

technical field [0001] The invention relates to the technical field of wire or cable processing equipment, in particular to a wire pay-off machine. Background technique [0002] The pay-off machine is a kind of auxiliary equipment for wires and cables that is matched with the stranding machine and plays the role of pay-off. When the pay-off machine is used for wire defense, the wires or cables that are usually released first pass through the wire-passing rollers and then pass through each wire-passing guide wheel for pay-off. Since the shaft on the winding shaft assembly is relatively long, when the wire or cable on the winding shaft leaves the winding shaft, due to its position on the winding shaft, it will move left and right on the wire passing roller, and the wire or cable will generate dynamic friction during the unwinding process. The magnitude of the dynamic friction force of the wire or cable is related to the pressure of the wire or cable. The friction force genera...

Problems solved by technology

Since the shaft on the winding shaft assembly is relatively long, when the wire or cable on the winding shaft leaves the winding shaft, due to its position on the winding shaft, it will move left and right on the wire passing roller, and the wire or cable will generate dynamic friction during the unwinding process. The size of the dynamic friction force of the wire or cable is related to the pressure of the wire or cable. The friction force generated between the cable and the wire passing roller is relatively large, and the wear on the outer skin of the wire or cable is relatively large.
