Packaging paper pad for inwards-drawing type copper coil pipe

Abstract

A packaging paper pad for an inwards-drawing type copper coil pipe is characterized by being formed by stacking a circular-ring-shaped first paper pad body and a circular-ring-shaped second paper pad body. The second paper pad body is stacked above the first paper pad body and is in contact with the copper coil pipe; arc-shaped hollow-out portions allowing a staggering layer of the copper coil pipe to be contained are circularly arranged in the second paper pad body, and the rotating direction of the hollow-out portions is opposite to the drawing direction of the copper coil pipe; the hollow-out portions are two continuous segments; the first hollow-out portion is of a gradually-wide arc-shaped structure with the narrow front end and the wide rear end, and the inner edge of the second hollow-out portion is in smooth connection with the inner edge of the first hollow-out portion; and the outer edge of the second hollow-out portion is in stepped reducing connection with the outer edge of the first hollow-out portion, and the second hollow-out portion is of a gradually-narrow arc-shaped structure with the wide front end and the narrow rear end. The packaging paper pad is simple in structure, firm and resistant to abrasion, and better solves the problem that the staggering layer of a bottom layer of the inwards-drawing type copper coil pipe is bent or broken; and the production efficiency is greatly improved, and the production cost is reduced.

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
