Packaging paper pad for copper coil pipe

Abstract

The invention provides a packaging paper pad for a copper coil pipe. The shape and the size of the packaging paper pad for the copper coil pipe are consistent with those of a bottom wood disc. A round connecting hole used for fixing a clamp is formed in the middle of the paper pad. Fixing holes are evenly distributed in the periphery of the connecting hole. Protruding blocks matched with the fixing holes are arranged at the opposite positions of the wood disc. The thickness of the protruding blocks is larger than that of the paper pad. Strip-shaped grooves are further formed in the paper pad. The packaging paper pad for the copper coil pipe is simple in structure and easy to operate, the packaging operation process cannot be increased, firmness and abrasion resistance are achieved, the problems that after the middle of the wood disc is stressed, the paper pad is prone to loosening, consequently, the paper pad cracks or falls off, and material clamping is caused are well solved, the fault occurrence rate is reduced, the production efficiency is improved, and continuous paying-off is achieved.

Description

technical field [0001] The invention relates to the technical field of copper coil packaging, in particular to a copper coil packaging paper pad. Background technique [0002] The most commonly used winding and unwinding method for copper coils is the external drawing type. The external drawing copper coils generally adopt the form of wooden plate, paper pad, copper coil tube, paper lining, paper pad, and wooden plate from bottom to top. For packaging, when the externally drawn copper coil is in use, the wooden disc is clamped by a clamp, and the copper coil is unfolded by the rotation of the motor. In the traditional technology, when the wooden plate is clamped by the clamp, the outer side of the wooden plate is stretched out due to the contraction of the middle part of the wooden plate, and the packing paper pad cannot be effectively pressed, resulting in an increase in the gap between the copper tube, the paper pad, and the wooden plate; loose The paper pad becomes loose...

AI Technical Summary

Problems solved by technology

In the traditional technology, when the wooden plate is clamped by the clamp, the outer side of the wooden plate is stretched out due to the contraction of the middle part of the wooden plate, and the packing paper pad cannot be effectively pressed, resulting in an increase in the gap between the copper tube, the paper pad, and the wooden plate; loose The paper pad becomes looser during rotation, and may even rotate relative to the copper coil, causing the paper pad to crack or fall off, which cannot effectively protect the copper coil and cause material jams
