Sheet resistance and the high characteristic of volume resistance, meanwhile, also with heat resistance, water resistance, chemical stability, high resilience, high stripping
From excellent physical properties such as property, very big fingerprinting stress and tensile strength.
As a rule, the paper machine of mica paper is similar with common paper machine principle, mainly include crushing, classification, slurrying,
The step such as manufacture paper with pulp, be molded, squeezing, drying, wherein, in forming process, relatively many molding modes are roll-forming, mica paper
Using mechanical roll-forming, mud jacking typically is carried out by two pressure rollers setting up and down for device for rolling and molding, during mud jacking,
By the radial direction to pressure roller away from being adjusted, to realize the calliper after mud jacking, still, in the prior art, for suppressing
The roller structure of mica paper is excessively simple, although realize the radial direction of pressure roller away from regulation, but during roll-forming, table
Face frictional force is smaller, and mica pulp and common paper pulp fiber pulp density are much bigger, are easily caused in nipping process
Paperboard or paper tape fracture.
Utility model content
The technical problem that the utility model is solved is to provide a kind of mica paper forming press-roller group, to solve above-mentioned background
Shortcoming in technology.
The technical problem that the utility model is solved is realized using following technical scheme：
Mica paper forming press-roller group, including the main nip rolls being arranged in groups and main pressure back of the body material roller, both upper and lower symmetrical cloth
Put, the main nip rolls includes roll body and the compound roll surface being molded on roll body, the roll body is metal material moulding, roll body
Outer surface is the high inner concave arc surface structure in low both sides along in the middle of axis, and the compound roll surface is molded over inner concave arc surface structural table
Face, low-friction coefficient contact layer, rubber filling layer and resin contact layer are outwards included from roll body successively, wherein, low friction system
Number contact layers are directly contacted with roll body outer surface, and rubber filling formable layer is in low-friction coefficient contact layer internal layer, and to roll body
Inner concave arc surface structure division realize it is levelling, and resin contact layer be molded over rubber filling layer surface be used for directly enter with paper pulp
Row roll-in is contacted.
In the utility model, the corresponding arc range of inner concave arc surface structure of the roll body is 4~5 °.
In the utility model, the low-friction coefficient contact layer is a strata tetrafluoroethene material layer, its thickness of application

In the utility model, the rubber filling layer is preferred to use butyl rubber or isoprene rubber or neoprene
It is filled.
In the utility model, the thickness of the resin contact layer is 3~5mm, preferably phenolic resin or asphalt mixtures modified by epoxy resin
Fat is molded.
In the utility model, one layer is formed on the interface between the rubber filling layer and the resin contact layer
Polypropylene fiber tissue layer.
Beneficial effect：It is of the present utility model simple in construction, easy to use, by setting inner concave on roll surface, and pass through
Contact surface and the flexible material filling of low friction are set in inner concave, can effectively be led to when either feeding speed is too fast in paperboard
The contact surface for crossing low friction turns round to prevent from pulling apart to keep continuity, and the roll surface of flexible material filling then can available energy it is effective
The stability of pressure roller in the process of running is improved, more suitable for the roll-forming of mica paper so that it is difficult in the course of the work
The problem of producing sound ring, disconnected paper, stacker and shaping paper lack of homogeneity.
