Description
Technical field
The utility model belongs to field of mechanical technique, relates in particular to a kind of extruding machine pullover.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame usually, and the follow-up equipment plastic extruding forming machine supporting with it is then called subsidiary engine.Pullover is exactly " the machine thorax " of plastic extruder, is the vitals realizing extruding.Pulloverly to be made up of inner sleeve and outer sleeve.Inner sleeve is except jointly accepting electrical heating with outer sleeve, play outside " thermal source " effect by conduct radiation to fuselage, most important effect is to coordinate with extruding screw, realize the fragmentation of plastics, softening, melting, exhaust preliminary consolidation, carry the effect of carrying sizing material to formation system continuously and equably, thus inner and outer sleeves is subject to HTHP for a long time, is rubbed for a long time and under the effect being operated in Korrosionsmedium.Pullover front end is then be vulnerable to most these impacts and deform or be corroded thus have impact on pullover smoothness, and stationarity makes the product processed not reach desirable index.In prior art, inner sleeve and outer sleeve are formed in one substantially, and corrosion resistance is poor, after the front end of inner sleeve and outer sleeve is damaged, get to know and scrap, must integral replacing, and production cost is high.Application number is the Chinese patent of 104210085A, separate a kind of extruder die, be provided with inner sleeve and outer sleeve, although decrease the shortcomings such as the corrosion resistance of die head to a certain extent, but due to the structure of the collar inside and outside it and the combination of inside and outside sleeve, make this structural stability bad, be subject to after the collar inside and outside HTHP produces tiny distortion, likely making the inside and outside collar be shifted and very directly come off, thus machine cannot normally be run.
Summary of the invention
A kind of structure that the purpose of this utility model is to overcome above-mentioned shortcoming and provides is simple, replacing is convenient, anticorrosive extruding machine that is strong, safe and reliable, good product quality is pullover.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions:
Extruding machine of the present utility model is pullover, comprise outer sleeve and inner sleeve, this inner sleeve is placed on formation circulation road in outer sleeve, wherein: the inner and outer sleeves place of described pullover front end is respectively equipped with inside race and outer collar, one section of outer wall of outer collar and one section of inwall of outer sleeve are fitted, fit in the left side of outer collar and the right side of outer sleeve, inwall and the inner sleeve outer wall of inside race are fitted, fit in the left side of inside race and the right side of inner sleeve, the outside of outer sleeve and inner sleeve is respectively equipped with outer end cap and inner end cap.
Above-mentioned extruding machine is pullover, wherein: described inside race and outer collar are separately fixed in inner and outer sleeves respectively by the inside and outside end cap of some screws.
Above-mentioned extruding machine is pullover, wherein: described outer sleeve and inner sleeve adopt the tetrafluoro template plastics of high temperature resistance high pressure as material.
The utility model compared with prior art, has obvious beneficial effect, as can be known from the above technical solutions:
The inner and outer sleeves place of pullover front end is respectively equipped with inside race and outer collar, one section of outer wall of outer collar and one section of inwall of outer sleeve are fitted, fit in the left side of outer collar and the right side of outer sleeve, inwall and the inner sleeve outer wall of inside race are fitted, fit in the left side of inside race and the right side of inner sleeve, the outside of outer sleeve and inner sleeve is respectively equipped with outer end cap and inner end cap, and inside race and outer collar are separately fixed in inner and outer sleeves respectively by some screws and the inside and outside end cap of some screws.In such design makes, outer collar has convertibility on the one hand, in making, whole outer sleeve or inner sleeve need not be changed when wearing and tearing or corrosion occur outer sleeve, save pullover replacement cost, on the other hand, in employing, outer end cap adds in screw general, in outer collar is fixed on, outer sleeve make lasso inside and outside wall contact with the inside and outside wall of sleeve when installing without the need to carrying out the cooperations such as interference, reduce installation difficulty, and decrease the horizontal holding capacity of sleeve and jacket wall, add the life-span of sleeve and lasso, even and if also there will not be phenomenons such as coming off at lasso generation subtle flow when being subject to HTHP, inside and outside sleeve adopts the tetrafluoro template plastics of high temperature resistance high pressure as material, plastic corrosion-resisting is strong on the one hand, compactness is good, add the fineness of pullover inwall, make making product have more compactness, greatly ensure that the quality of product, high temperature resistance high pressure material can ensure pullover quality greatly on the other hand, make it not easily to produce distortion, stress equalization, improve the service life of equipment.In a word, extruding machine of the present utility model is pullover, has the advantages that structure is simple, change convenient, anticorrosive strong, safe and reliable, good product quality.

detailed description of the invention:
Below in conjunction with accompanying drawing and preferred embodiment, to according to the pullover detailed description of the invention of extruding machine, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
See Fig. 1, extruding machine of the present utility model is pullover, comprise outer sleeve 1 and inner sleeve 5, this inner sleeve 5 is placed on formation circulation road 7 in outer sleeve 1, wherein: the inner and outer sleeves place of described pullover front end is respectively equipped with inside race 3 and outer collar 2, one section of outer wall of outer collar 2 and one section of inwall of outer sleeve 1 are fitted, fit in the left side of outer collar 2 and the right side of outer sleeve 1, inwall and inner sleeve 4 outer wall of inside race 3 are fitted, fit in the left side of inside race 3 and the right side of inner sleeve, the outside of outer sleeve 1 and inner sleeve 4 is respectively equipped with outer end cap 8 and inner end cap 4; Described inside race 3 and outer collar 2, respectively by some screws 6, are separately fixed in inner and outer sleeves with inside and outside end cap; Described outer sleeve 1 and inner sleeve 8 adopt the tetrafluoro template plastics of high temperature resistance high pressure as material.
When using in fact, the material from extruding machine passes through logistics corridor 7, namely extrudes between outer sleeve 1 and inner sleeve 8, evacuates, then uniform discharge.And be the most easily stressed in this process, high temperature, corrosion part be outer collar 2 and inside race 3, be separately fixed in inner and outer sleeves by some screws and the inside and outside end cap of some screws, and all adopt high temperature resistance high-pressure type to mould manufacture, corrosion resistance is strong, therefore outer collar 2 and the replaceable collar of inside race 3, and more after new construction, inner and outer ring stationarity is better, lateral stressed reduction, thus longer service life.In a word, the utility model instead of the pullover of one, improves pullover stability, and change the collar timely and also improve pullover precision, make the product accuracy of discharging higher, reliability is stronger.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, any content not departing from technical solutions of the utility model, the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
