Description

A kind of mica paper feeding-in roll

Technical field

The utility model is related to paper making equipment field of accessories, and a kind of specially mica paper applied to mica paper paper machine is sent Paper bowl.

Background technology

Mica is the general name of a class hydrous alumino silicates class, and it has electrical strength high, and dielectric loss is low, sheet resistance and Volume resistance is high, with heat resistance, water resistance, chemical stability, high resilience, high fissility, very big fingerprinting stress and anti- The excellent properties such as Zhang Qiangdu, mica paper is a kind of nonmetallic mineral material of paper-like, and it is the head using fine platy garrulous mica as raw material First pass through and mica is broken into tiny scale through heat chemistry or waterpower stripping point, in the case of not any adhesive, pass through Classification, slurrying and then on mica paper machine, manufacture paper with pulp shaping by the sucking action of Van der Waals force and squeezing drying form coiled material Or individual mica paper.

As a rule, the paper machine of mica paper is similar with common paper machine principle, but using tradition more than its carrying roller part Metal roll structure, its single roller heavier mass, and skin-friction force is smaller, and because mica paper and common paper pulp fiber paper are close Degree and surface smoothness all difference, thus traditional feeding-in roll to be sent mica paper when the more difficult control of its line feed, When paper tape translational speed is excessive, the steady movement of paper tape can be influenceed, especially when production needs the mica paper by cutting, Because paper is cut into fritter, movement is more difficult to be restricted, is very easy to cause paper to tilt transmission between two rolls, So as to cause quality problems；And if paper tape translational speed it is too small when, coil paper efficiency can be influenceed again.

Utility model content

The technical problem that the utility model is solved is to provide a kind of mica paper feeding-in roll, to solve above-mentioned background technology In shortcoming.

The technical problem that the utility model is solved is realized using following technical scheme：

A kind of mica paper feeding-in roll, including roller and roll shaft, wherein, roll shaft is fixedly connected on roller by connecting bracket On the end face of both sides, and the roller includes roll body and the detachable roll surface being molded on roll body, and the roll body is metal material Shaping, is provided with some bulge-structures be arrangeding in parallel on its roll body outer surface, these bulge-structures by soft abrasive rubber into Type, its vertical section is mushroom, is annularly arranged on the vertical section of roll body, and the gap of adjacent bulge-structure for 30~ 60mm。

As further improvement of the utility model,

The detachable roll surface is molded over the bulge-structure surface of roll body, including the butyl contacted with the bulge-structure of roll body Rubber layer and the novolac resin layer for being molded over butyl rubber layer surface, and form in phenolic resin aspect latticed line Road, the ratio between the thickness of the butyl layers and novolac resin layer is 2: 1, and both thickness sums are 2~3mm.

The top surface of the bulge-structure is minor arc cambered surface.

The bulge-structure and roll body is are detachably connected, and it is detachably connected mode and is：Roll body is uniformly set on outer surface Be equipped with some length dovetail groove consistent with bulge-structure length or I-shaped groove, and the base portion of bulge-structure be with dovetail groove or The inserting molding structure that person's I-shaped groove matches.

Beneficial effect：Feeding-in roll of the present utility model is simple in construction, can soft rubber material be molded bulge-structure with And paper feeding is carried out under the collective effect of double-deck roll surface, its paper feeding stability is good, more suitable for the conveying of mica paper, in paper feeding process In be not likely to produce the problems such as paper feeding is bad, sound rings, and during mica paper paper transport, pass through two or more rollers Shi Xiaoguo more preferably, can make that paper is continuous, smoothly enter next process.
