Adjustable take-up and pay-off stand

Abstract

The invention discloses an adjustable take-up and pay-off stand, and belongs to the field of mechanical equipment. The adjustable take-up and pay-off stand comprises a fixed part and a rotating part, wherein the fixed part comprises a first pedestal, a fixed ring and a first connecting rod; the rotating part comprises a second pedestal, a motor, a second connecting rod, a protective ring, a rotating frame, a fixed seat, a guide seat and two to four guide rods; the motor is arranged at the upper end of the first pedestal and is fixedly connected with the second pedestal, and the lower end face of the second connecting rod is provided with a roller; the roller comprises a positioning wheel, a cylindrical wheel and an wheel axle; one end of the second connecting rod is fixedly connected with the second pedestal, and a loop bar is arranged on the other end of the second connecting rod in a sleeving manner; a protective ring circular arc block is fixedly arranged at the other end of the loop bar; the guide rods are equally spaced from one another on the guide seat, are in threaded connection with the guide seat and all form an included angle of 10-30 degrees with the horizontal line. Loosening and winding during pay-off can be avoided, active pay-off is realized, the bearing capacity of one-time pay-off can be adjusted, the bearing capacity is improved by arranging the roller, and the stand adapts to spools of different sizes and materials.

Description

technical field [0001] 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 [0002] 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 smooth and entangled with each other, which not only wastes materials, but also affects the smooth progress of application projects. In order to solve these problems, people usually put large packages of yarn, thread, ...

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
