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 with the poly- of the limitation deflection deformation of compression roller 10
The extrusion body of diphenyl sulfide casting films 7, for casting films 7 (herein referring to polyphenylene sulfide casting films 7, similarly hereinafter) to be squeezed into
Type, this extrusion body of polyphenylene sulfide casting films 7 with the limitation deflection deformation of compression roller 10 includes that maintaining body and two is squeezed
Pressure roller 10, two compression rollers 10 be arranged in parallel, and maintaining body includes being respectively arranged at the bearing block 30 at the two ends of two compression roller 10, is used for
Push against the spring 40 of the bearing block 30 at the two ends of two compression roller 10 and for making the vertical shift of bearing block 30 and being located at compression roller 10
The holding seat 20 of both sides, spring 40 causes that two compression rollers 10 extrude casting films 7 with predetermined compression power, wherein, compression roller 10 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 by metal material
Material is made and wears the mandrel 1 of interior roller set 2, wherein, mandrel 1 is multidiameter shaft, and the diameter of mandrel 1 gradually subtracts from middle part to two ends
It is small, annular gap is formed between interior roller set 2 and mandrel 1, graphite 4 is filled with annular gap.Wherein, keep being opened up on seat 20
There is the gathering sill 21 being vertically arranged, bearing block 30 is arranged in gathering sill 21 and can be along the vertical shift of gathering sill 21, this practicality
New it is critical only that：1st, mandrel 1 is arranged to multidiameter shaft, makes the mid diameter of mandrel 1 more than two ends diameter and from middle part to two
Its uniform diameter is held to change, according to material mechanics principle, because compression roller 10 is in two ends stress F, the middle part moment of flexure of compression roller 10
More than two ends, but 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 and two ends
Deflection is more or less the same, and linearity changes less (will not produce large curved in other words) compression roller 10 before stress and after stress
So that the gap between two compression rollers 10 is almost identical in the axial direction, so that the casting films 7 for squeezing out are in the direction of the width
Thickness is uniform and mechanical property is identical；2nd, graphite 4 is filled with annular gap, graphite 4 does not possess the ability of elastic deformation,
The elastic modelling quantity of graphite 4 is almost 0 in other words, and the graphite 4 is only used for for the deformation of mandrel 1 and power passing to interior roller set 2, so that
Make the size of mandrel 1 is being calculated and designed according to theory of mechanics of materials so as to produce uniform gap process between two compression rollers 10
In, the influence factor without considering (or hardly considering) graphite 4.For example, calculating in the axial direction flat of compression roller 10
When equal elastic modelling quantity and deformation, just need to can only be calculated according to interior roller set 2 and mandrel 1, so as to simplify computation model, make work
Journey technical staff obtains accurately design size more easily by calculating.
Squeezing with the extrusion body of polyphenylene sulfide casting films 7 for limiting the deflection deformation of compression roller 10 of the present utility model
Pressure roller 10 solves the problem in uneven thickness in the direction of the width of casting films 7 due to being provided with the mandrel 1 of reducing, prior
It is that annular space filling graphite 4 can simplify the design and calculating process of compression roller 10.
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 compression roller 10 each position in the axial direction of compression roller 10.
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 compression roller 10 is calculated, and the outer roller covers 3 also as graphite 4, only
Transmission extruding force.
Should explain：Above-mentioned " predetermined compression power " is to refer to be squeezed into casting films 7 to meet thickness requirement and mechanics
The extruding force of performance requirement, the extruding force is provided by spring 40, therefore, need to be compressed to spring 40 can produce the extruding force
Degree.
Preferably, elastic modelling quantity of the elastic modelling quantity of mandrel 1 more than interior roller set 2.It is arranged such and is advantageous in that so that tool
The deflection deformation of the extrusion body of polyphenylene sulfide casting films 7 of the deflection deformation of restricted compression roller 10 depends primarily on mandrel 1,
Even if the uniformity of the thickness of casting films 7 depends primarily on mandrel 1, in this way, when calculating and designing compression roller 10, main basis
Mandrel 1 is calculated, and so as to simplify calculating process, shortens the design process of compression roller 10.
Used as further preferred, the two ends of interior roller set 2 are provided with the plug 5 for blocking annular gap.
Used as further preferred, the end of outer roller set 3 protrudes from interior roller set 2, and the two ends of outer roller set 3 are respectively arranged with capping
