A wrapping paper pad for internally drawn copper coils

Abstract

A wrapping paper pad for internally drawn copper coils, characterized in that: the wrapping paper pad is formed by stacking circular first paper pads and second paper pads, and the second paper pad is superimposed on the first The top of the paper pad is in contact with the copper coil tube, and the second paper pad is surrounded by an arc-shaped hollow part for the interlaced layers of the copper coil tube to be inserted. The rotation direction of the hollow part is opposite to the extraction direction of the copper coil tube. The part is two continuous sections, wherein the first hollow part is an arc-shaped structure with a narrow front end and a wide rear end, the inner edge of the second hollow part is smoothly connected with the inner edge of the first hollow part, and the inner edge of the second hollow part The outer edge is connected to the outer edge of the first hollow part in a stepped diameter-reducing shape, and the second hollow part is in an arc-shaped structure with a wide front end and a narrow rear end. The invention is simple in structure, strong and wear-resistant, better solves the problem of bending or breaking of the interlaced layers at the bottom of the inner-drawing copper coil pipe, greatly improves production efficiency, and reduces production cost.

Description

technical field [0001] The invention relates to a wrapping paper pad, in particular to a wrapping paper pad for an internally drawn copper coil. Background technique [0002] The most commonly used winding and pay-off method for copper coils is the external drawing type. During the operation, the motor is used to rotate, causing the copper coils to continue to unfold. The production cost is high, and it is also easily affected by the site, which is not convenient for large-scale production. [0003] At present, the inner pumping copper coil tube that has been developed and applied has a simple package structure, convenient operation, firm packaging, and convenient transportation, and the copper tube can be unfolded in an orderly manner without the use of equipment. However, in the process of extracting and unfolding the inner-drawn copper coil, due to the influence of the structure of the paper pad, the bottom layer of the copper coil that is in contact with the paper pad is...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a simple and reasonable wrapping paper pad for inner-drawn copper coils in view of the above-mentioned technical status, which solves the problem that the interlaced layers at the bottom of the copper coil are easy to bend or break , which can realize continuous extraction of copper coils and improve production efficiency
