Description

The high polymer elastic assembly that is used for packed steel coil

Technical field:

The utility model relates to a kind of annular object that is used to pack, and particularly relates to a kind of rubber-like package component packed steel coil class object and that made by High molecular material that is used for.

Background technology:

Because exposed cold rolling roll bending or coil of strips such as zinc-plated roll bending or color coating roll bending are very easily impaired or by oxide erosion such as water in lifting and storage process, for guaranteeing the integraty of its coil of strip, after these coil of strips form, need its surface to be packed, to prevent the generation of above-mentioned situation with packaging element.Yet the packaging element of selecting suitable material and shape is to guarantee one of the coil of strip quality very key link.Pack the packaging element of above-mentioned coil of strip in known being used for, the packaging element of making of plastics and paper is generally adopted.

Packaging element with plastic production has two types in the prior art, one type plastic wrapping element is to adopt and identical with the outer shroud shape or the akin wheel shape member of the interior ring of coil of strip end, and what the name of announcing as CN2118052U was called " steel plate packaging plastics backplate " employing is exactly this structure.Its meaning is to want to utilize plastic product that the annular edge edge of coil of strip end is enveloped, and is without prejudice with the protection coil of strip.And from the content disclosed in this patent, this kind backplate is to be raw material with polyethylene, rubber end, colorant, french talc, and is molded through the heating plasticizing agent.For plastic product, it in case behind the thermoplastic extrusion forming its shape just be fixed, and only has rigidity, and do not have elasticity, so can not be arbitrarily in packaging process with its increase or dwindle, can only be used for identical with its shape or the akin coil of strip of packing, but coil of strip is not a kind of very accurate final products, even the coil of strip of same specification, its external form also are difficult to reach identical, so, the backplate that has a fixed measure with this kind is difficult to reach with all coil of strips and is complementary, if backplate oversize and bigger gap can appear between the two in inadequate use, and when tying up, easily cause the backplate fracture; If backplate is undersized, this backplate can not use basically, and then causes waste.

With the packaging element of the another kind of type of plastic production is the element that adopts a kind of microscler and variable folding, and being called " a kind of Plastic protective corner that is used for packed steel coil " as the name of No. 2490104 bulletins of Chinese patent is exactly this element.This kind corner protector adopted one that be made of plastics and be provided with the longitudinal bodies of saw shape tooth along a limit of its length, and be provided with hasp in two ends of main body.Its meaning be want to utilize longitudinal bodies with loose structure and hasp solves and coil of strip between matching problem.But, because plastic product is a kind of rigid material, and be subjected to the influence of ambient temperature bigger, when tying up steel band, can directly cause corner protector to produce ripple to its bigger application force, fluid enters the coil of strip surface by the boss of ripple, easily make coil of strip corrosion in long-term storage process, when ambient temperature is lower or higher, easily make its fracture or deliquescing, so, use the packaging element of plastic production to be not suitable for heavy wares such as packed steel coil.

Though the relative plastics of paper have certain flexible, but the undercapacity of paper products, and hygroscopic character is big, so, must there be the stack of laminated paper to make it become a kind of plate made of paper with paper as the element of packed steel coil, simultaneously also must scribble waterproof and rust proof layer on its surface, being called " a kind of Plate material package corner protector " as the name of Chinese patent 2548938 bulletins is exactly corner protector with the paper making.This kind corner protector has adopted a block length shape cardboard, and a long limit of cardboard is provided with that serration is regulated mouthful and folding line, and it is regulated mouthful is to be folded the limit and to be unlikely to occur ripple in order it to be curled into when circular and folding, to make.Yet, because this paper products does not have elasticity and flexibility, when its circumferencial direction along the interior ring surface of coil of strip is curled, the position that to regulate simultaneously mouthful is as the criterion alignment coil of strip end face when folding with folding line, mouthful become big because the circle footpath of regulating mouthful increases to force to regulate, water or other fluid very easily flows into the coil of strip surface and directly corrodes coil of strip by bigger adjusting mouth; On the other hand, be provided with too smallly in advance as regulating mouth, because corner protector made of paper is subjected to elasticity and flexible restriction, this corner protector can vertical folding line occur regulating the oral area position, even can be fractureed.In addition, paper products does not have adiathermancy, when having water or other fluid between corner protector and coil of strip, as the ambient temperature height, can impel its evaporation, and easier its surface corrosion that makes of steam.

Summary of the invention:

Task of the present utility model provide a kind of utilize that High molecular material makes make it have elasticity and flexibility, and the high polymer elastic assembly that is used for packed steel coil of heat insulating function is to overcome above-mentioned weak point.

The high polymer elastic assembly that is used for packed steel coil that the utility model proposed, comprise the elastin pavement plate and the elasticity corner protector plate that is used to be coated on the coil of strip end and have serration opening or cutting mouth, the elastic component that described mask plate and corner protector plate are made by copolymerization and/or foaming mode by High molecular material that can be wound on the coil of strip cylinder.

Described corner protector plate comprises outer corner protector plate and inner protective corner plate, the corner protector plate long limit is provided with relatively large serration opening outside, and a long limit of inner protective corner plate is provided with cutting mouth, and the serration opening of outer corner protector plate and inner protective corner plate or the below of cutting mouth are provided with folding line.
