Packing structure and corner protection for preventing steel strip bare coil from damaging packing material

Abstract

The invention discloses a packing structure and a corner protection for preventing a steel strip bare coil from damaging packing material. The packing structure comprises a steel coil, a steel coil turnup edge, a corner protection body, an inner core anti-rust paper, a peripheral anti-rust paper, a polyethylene film, a corrugated board, a plastic protection plate, a steel protection plate and corner angle protections, wherein a binding belt is bound around the peripheral direction of the bare coil of the steel coil. From the inside of the steel coil out, the inner core anti-rust paper is arranged on the inner core face of the steel coil, the width of the inner core anti-rust paper is equal to the width of the steel coil, the corner angle protections are respectively arranged on the outer sides of two portions, located on corner angles of two end faces of the inner core face of the steel core, of the inner core anti-rust paper, the corner angle protections are of plastic material, the corner protection body is arranged at the edge corner of the steel coil turnup edge on the periphery of the steel coil, the corner protection body is of right angle housing structure, the corner protection body is formed by injecting the plastic material, the thickness of the plastic material is 2-3.5mm, and a corner angle of the corner angle protection body is of round angle structure. The packingstructure can protect the sealed material from being damaged by the sharp corner of the steel coil turnup edge and the edge corner on the side face of the steel coil turnup edge, can further protectthe sealed material in all directions, and meanwhile is simple in structure, free of limits of the outer diameter and the width of the steel coil, and strong in universality, can meet use requirementsof most steel coils, improves packing efficiency, and achieves obvious effects.

Description

technical field [0001] The invention relates to the field of packaging of cold-rolled steel coils, in particular to a packaging structure and corner protectors for preventing bare steel coils from damaging packaging materials. Background technique [0002] In the current cold-rolled steel strip packaging industry, the steel strip packaging process is basically similar, and its main functions are anti-rust sealing, buffer protection, binding and anti-loosening, etc.; the packaging material that plays the role of anti-rust sealing is used close to the surface of the steel strip, from From the inside to the outside, there are anti-rust sealing, cushioning protection, binding and anti-loosening packaging materials, among which the function of cushioning and protection packaging materials is mainly to protect the anti-rust sealing packaging materials from external factors. However, in actual use, due to the influence of regions, transportation distances, transportation methods, t...

AI Technical Summary

Problems solved by technology

However, in actual use, due to the influence of regions, transportation distances, transportation methods, transit hoisting, etc., the rust-proof sealing material is often damaged, which seriously affects the sealing performance; after research on the damaged location, it is found that the rust-proof seal The location where the packaging material is damaged includes the position of the warped edge of the steel strip, especially the steel strip with a thicker steel plate is more serious. After each transportation, loading and unloading, it will be damaged, which will further cause local rust on the steel coil
