Adjustable take-up and pay-off rack

Abstract

The invention discloses an adjustable take-up and pay-off rack, and belongs to the field of mechanical equipment. The adjustable take-up and pay-off rack comprises a fixed part and a rotating part. The fixed part comprises a first base, a fixed ring and first connecting rods. The rotating part comprises a second base, a motor, second connecting rods, a protection ring, rotating frames, a fixed seat, a guide seat and guide rods. The motor is arranged at the upper end of the first base and is fixedly connected with the second base. A rolling wheel is arranged on the lower end face of each secondconnecting rod and comprises a locating wheel, a cylindrical wheel and a wheel shaft. One end of each second connecting rod is fixedly connected with the second base, the other end of each second connecting rod is sleeved with a sleeve rod, and a protection ring arc block is fixed to the other end of each sleeve rod. The two to four guide rods are arranged on the guide seat at equal distance andare in threaded connection with the guide seat, and an included angle ranging from 10 degrees to 30 degrees is formed by each guide rod and the horizontal line. According to the adjustable take-up andpay-off rack, wire off and winding can be avoided in the pay-off process, active paying off can be achieved, and the bearing capacity of one-time paying off can be adjusted; and the rolling wheels are arranged to improve the carrying capacity, and the adjustable take-up and pay-off rack can be suitable for wire coils of different sizes and materials.

Description

[0001] This application is a divisional application with the application number 2014106321824, the application date of November 12, 2014, and the title of the invention "An adjustable take-up and release wire stand". technical field [0002] The invention belongs to the field of mechanical equipment, and more specifically relates to an adjustable take-up and pay-off wire rack. Background technique [0003] In various engineering technologies, flexible yarns, threads, tapes, ropes, and cables with lengths are commonly used. In order to reduce volume and facilitate transportation and storage, production units usually wind these yarns, threads, tapes, ropes, and cables into For large packages of different specifications, when the user uses these packaged products, they will be unwound from the package at the construction site. If effective control cannot be carried out during the unwinding process, flexible yarns and threads will The unwinding of belts, ropes and cables is not ...

AI Technical Summary

Problems solved by technology

Existing yarns, threads, ribbons, ropes, and cables are usually made into packages with mandrels or pancake-shaped packages without mandrels. In the process, if the pulling direction is too high, the yarn, thread, tape, rope, and cable wound on the pay-off frame will be off-line, resulting in poor unwinding and mutual entanglement. At this time, the machine must be stopped and the Scattered yarns, threads, belts, ropes, and cables are rewound, seriously affecting the smooth progress of production or engineering

And in the prior art, the pay-off stand completely relies on the external force to pull the wire to realize the release during the pay-off process, so it will have a certain stretching damage effect on the yarn, thread, belt, rope, and cable, and serious damage to the wire will occur. The phenomenon that the material is pulled off, and the existing pay-off rack is constant for the one-time pay-off amount carried by it. If the wire reel is large, it is necessary to replace a larger pay-off rack, which is troublesome. If the wire reel is larger Small, then there will be a waste of wire reels and workshop space
