Abstract

The present invention proposes a kind of rubber roll, and including roller core, roller core surface is coated with polyurethane rubber layer, is positioned at the both sides of polyurethane rubber layer on roller core surface and is also covered with exotic material, and described exotic material and polyurethane rubber layer slitless connection；The width of described polyurethane rubber layer determines according to the width size of required work surface when using；Described exotic material is nylon material.The glue-line of roll surfaces of the present invention parcel is divided into the working region of middle part and the non-active area at two ends, working region and non-active area use different material exotic materials, thus avoid the non-active area of rubber roll both sides than working region aging polluted product fast, easy and with short problem of new cycle.

Description

A kind of rubber roll

Technical field

The invention belongs to print articles for use technical field, be specifically related to a kind of rubber roll.

Background technology

Rubber roll is with metal or other materials as core, is cladded with the roll goods that polyurethane material is made.Can divide according to purposes For papermaking rubber roller, printer's roll, printing rubber roll, paddy hulling rubber roll, metallurgical rubber roll and mimeograph rubber roll etc..Use polyurethane material When material makes rubber roll, typically made by one-time cast-forming, roller core is positioned by upper lower flange, be secured centrally to circle In cylindrical mold；Rubber liquid sizing material is cast in die cavity, is fully coated with whole roll surface, makes liquid sizing material by heating Curing molding；Then disengageding mould, by being machined to finished product required size.When rubber roll uses, typically on work station With corresponding heated steel roll cooperating, between rubber roll and heated steel roll, place the materials such as paper to be processed, aluminium sheet, thin film Material.In order to ensure crudy, the width of the polyurethane glue-line of roller core outsourcing can be more than the width of material to be processed, now The part that polyurethane glue-line directly contacts with material to be processed is referred to as work surface, between work surface is due to heated steel roll There is also material to be processed, these materials to be processed play certain thermal insulation protection effect virtually so that rubber roll works The temperature on face actual temperature heated steel roll to be far below surface, but it is positioned at the polyurethane adhesive layer segment beyond work surface, generally Be in work surface both sides be not covered with material to be processed polyurethane adhesive layer segment need directly contact with heated steel roll, hold High temperature and high pressure by heated steel roll.So, rubber roll, during life-time service, is positioned at work surface both sides and is not covered with treating The polyurethane glue-line of rapidoprint, owing to directly contacting with heated steel roll, drinks the direct of roasting and heated steel rider long-term In the case of rolling, compared with the polyurethane glue-line in work surface region, easy premature aging, it may appear that variable color, cracking, Carbonization, melt, fall the phenomenons such as block and glue-line and roller core disengaging, thus in rubber roll works, pollute work surface, even may be used Processed product can be polluted；The glue-line of premature aging is elastic, toughness declines, and affects product quality；Cracking, the glue of carbonization Layer also results in and the pressure imbalance to roller, produces vibrations when causing equipment to do manual work, and when rubber roll two ends occur that block is existing As, easily equipment is run well and cause relatively macrolesion, cannot normally use, glue-line cladding need to be re-started.

Summary of the invention

Present invention aims to the problem that existing rubber roll glue surface two ends exist the resistance to temperature difference, it is provided that a kind of novel glue Roller, the glue-line of its roller core surface parcel is divided into the working region of middle part and the non-active area at two ends, working region with Non-active area uses different material exotic material, thus avoids the non-active area of rubber roll both sides older than working region Change polluted product fast, easy and with short problem of new cycle.

In order to solve above-mentioned technical problem, the present invention provides a kind of rubber roll, and including roller core, roller core surface is coated with polyurethane Rubber layer, the both sides being positioned at polyurethane rubber layer on roller core surface are also covered with exotic material, and described exotic material With polyurethane rubber layer slitless connection；The width of described polyurethane rubber layer is according to the width size of required work surface when using Determine.

Described exotic material is nylon material.

Described nylon material is Fypro casting type nylon, poly-decylene decanedioyl amine type nylon, fatty polyamide One or more in type nylon, chinlon 66 chopped fiber nylon, barrier properties resin type nylon, enhancing nylon.

Compared with prior art, its remarkable advantage is the present invention, the present invention roll surfaces is divided into working region and Non-active area, wherein non-active area is formed by exotic material, improves the resistance to elevated temperatures of non-active area, keeps away Exempt to occur variable color, cracking, carbonization, melt, fall block and with the phenomenons such as roller core disengaging, make non-active area be difficult to aging, Improve rubber roll service life and utilization rate, reduce customer using cost.

Accompanying drawing explanation

Fig. 1 is rubber roll schematic diagram of the present invention.

Detailed description of the invention

Easy to understand, according to technical scheme, in the case of the connotation not changing the present invention, this area Those skilled in the art can imagine the numerous embodiments of rubber roll of the present invention.Therefore, detailed description below and attached Figure is only the exemplary illustration to technical scheme, and is not to be construed as the whole of the present invention or is considered as this The restriction of bright technical scheme or restriction.

Rubber roll of the present invention, the both sides being positioned at polyurethane rubber layer on roller core surface are also covered with exotic material, polyurethane rubber Glue-line region, as work surface, operationally directly contacts with processed product, the exotic material district that both sides cover Territory is non-active area, directly contacts, because it is compared with polyurethane rubber layer with as to the heated steel roll of roller during work The more preferable material of resistance to elevated temperatures, even if therefore under long term high temperature scorches, also will not be than polyurethane rubber layer premature aging.

In order to ensure that exotic material is consistent with the grinding performance of polyurethane rubber layer, hardness in use, elasticity, change Shape keeps consistent, and the present invention selects with polyurethane further in parameters such as hardness, intensity, elasticity, abrasion and permanent deformations Close nylon material carry out with the use of；Wherein, nylon material can select MC nylon (Fypro further Casting type nylon), nylon 1010 (poly-decylene decanedioyl amine type nylon), Stanyl (DSM). (fatty polyamide type nylon), Nylon66 fiber (chinlon 66 chopped fiber nylon), MXD6 (barrier properties resin type nylon), enhancing nylon (add in nylon Add the material such as glass fibre, toughener, to increase the strength of materials) etc. concrete high temperature resistant, intensity is high, deform little Buddhist nun Dragon material.Meanwhile, these nylon materials and polyurethane rubber are two kinds of independent chemical substances, the most not existence Learn reaction, to produce chemical reaction between avoiding phase factor mutually but glue surface deforms upon or complexion changed.

Wherein, the width in work surface region depends on the effective width of processed product, and described exotic material and poly-ammonia Ester rubber layer slitless connection.

While the present invention improves rubber roll two ends heat resistance, the bi-material coefficient of waste and compression set rate are very Close, ensure that the synchronicity of rubber roll globality and change during use, it is to avoid the product therefore brought is inapplicable.
