Description
Technical field
The utility model relates to a kind of shock resistance, tear-proof rubber roll.
Background technology
Rubber roll is widely used in viscose rayon, in industry production line water squeezing such as papermaking, iron and steel, leather, printing and dyeing, plastics and the squeezing process.As shown in Figure 1, traditional rubber roll is made of steel roller core, adhesive layer, rubber layer.In production line water squeezings such as viscose rayon, papermaking, leather and squeezing process process, the linear pressure that rubber rollers is normally born is generally at 50-300 ㎏/㎝, can cause local instantaneous pressure to explode in case occur situations such as fiber accumulations is inhomogeneous, the axle pressure at two ends is inhomogeneous, in uneven thickness, foreign matter enters in the production process, stress concentrations, impulsive force is directly delivered to adhesive layer by rubber layer, cause adhesive layer to separate with roller core, cause the part of rubber roll or the rubber layer at two ends to be subjected to major injury, greatly reduce the service life of rubber roll.
The applying date is that the Chinese patent ZL2009201989449 on October 26th, 2009 discloses a kind of large-scale papermaking rubber roller, this rubber roll comprises that roll body and coating are arranged on the rubber layer on the roll body, its rubber layer comprises primer layer one, primer layer two, intermediate gelatine layer and face glue-line from inside to outside successively, between primer layer one and primer layer two the steel wire enhancement layer is set.This rubber roll is by arranging the steel wire enhancement layer in primer layer, the steel wire enhancement layer is changed fragility, the creep properties of primer layer as the framework material of primer layer, strengthens the peel strength of primer layer and roll body, thereby reaches the technical purpose in prolongation rubber roll life-span.Whole crush resistance, resistance to overturning tool that the disclosed enhancement layer of above-mentioned patent application adopts steel wire to make rubber rollers are greatly improved, but mostly rubber roll its damage in use is to be damaged because the part is impacted.The hard fritter impurity that in the extruding rotation process, occurs in the pressing material for example, the contact-making surface of itself and rubber roll is very little, under the powerful extruding force effect of rubber roll, impurity raises suddenly to the pressure on rubber roll top layer, because of top roller diameter less, the suffered local assault in its top layer is circumferentially decomposed limited along roll body, therefore cause the rubber roll top layer often along the roll body circumferential break, causes rubber roll to damage.Therefore the effective improvement method that prolongs the service life of rubber roll is how the local pressure on rubber roll top layer effectively to be decomposed, and the local assault amount of overcoming that the rubber roll top layer is subjected to is decomposed vertically, to subdue the radial impact to rubber roll.
In addition, the steel wire enhancement layer that adopts in the above-mentioned patented technology can cause the radial elastic of rubber roll to diminish, and shock-absorbing capacity weakens.
