Schematic diagram.
Specific embodiment
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Mode is applied to elaborate the utility model.
As shown in Fig. 1 to 2, embodiment of the present utility model discloses a kind of for processing squeezing for polyphenylene sulfide casting films 7
Pressure roller, for by casting films 7 (herein referring to polyphenylene sulfide casting films 7, similarly hereinafter) extrusion forming, for processing polyphenylene sulfide curtain coating
The compression roller of film 7 includes the outer roller set 3 being made up of nylon material, the interior roller for being made and being arranged in outer roller set 3 by metal material
Cover 2 and the mandrel 1 that interior roller covers 2 is made up and worn of metal material, wherein, mandrel 1 is multidiameter shaft, and the diameter of mandrel 1 is in
Portion is gradually reduced to two ends, and annular gap is formed between interior roller set 2 and mandrel 1, and graphite 4 is filled with annular gap.This reality
Be it is critical only that with new：1st, mandrel 1 is arranged to multidiameter shaft, make the mid diameter of mandrel 1 more than two ends diameter and from middle part to
Two ends its uniform diameter change, according to material mechanics principle, because roller is in two ends stress F, the middle part moment of flexure of roller is more than two ends, so
And the diameter at middle part is big such that it is able to increase the ability of resist torque, so that the deformation at middle part is differed with the deflection at two ends
Less, roller before stress and after stress linearity change less (large curved will not be produced in other words) so that between two rollers
Gap is almost identical in the axial direction so that the casting films 7 for squeezing out thickness is uniform in the direction of the width and mechanical property phase
Together；2nd, graphite 4 is filled with annular gap, graphite 4 does not possess the ability of elastic deformation, in other words the elastic modelling quantity of graphite 4
Almost 0, the graphite 4 is only used for for the deformation of mandrel 1 and power passing to interior roller set 2, so that according to theory of mechanics of materials
During the size of mandrel 1 is calculated and designed so as to produce uniform gap between two rollers, without considering (or hardly considering) stone
The influence factor of ink 4.For example, when roller average elastic modulus in the axial direction and deformation are calculated, only need to be according to interior roller
Set 2 and mandrel 1 just can be calculated, and so as to simplify computation model, make engineers and technicians accurate more easily by acquisition is calculated
Design size.

Casting films 7 problems in uneven thickness in the direction of the width, it is often more important that, annular space filling graphite 4 can simplify roller
Design and calculating process.
Annular gap is filled with graphite 4 so that graphite 4 is only involved in power and displacement transfer, without producing drag to deformation, from
Deflection without influenceing elastic modelling quantity and roller each position in the axial direction of roller.
Should explain：Because outer roller set 3 is made up of nylon material, its elastic modelling quantity very little, almost without elastic resistance, because
This, its influence to overall deformation is not considered when the deformation of roller is calculated, and the outer roller covers 3 also as graphite 4, only transmits and squeezes
Pressure.
