Description
Technical field
This utility model is related to a kind of screw cylinder, more particularly to a kind of new screw that can extrude evaporation raw material moisture
Barrel.
Background technology
Screw cylinder is mainly used in injection machine, is a kind of for plastic raw materialss are carried out by the screw thread annular groove on threaded rod
Extruding conveying the equipment of pelletize.The width of the screw thread annular groove on the threaded rod of existing screw cylinder is all identical, and raw material is squeezed
Uniform force in pressure course of conveying, the temperature of raw material are consistent, will not locally raise, not evaporate the function of moisture, so, raw material
Raw material stoving must be carried out before into screw cylinder, which adds drying plant cost and drying time human cost.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of without the need for the new of advance drying material
Type screw cylinder.
This utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of new screw barrel, including outer tube and threaded rod, central through hole of the threaded rod through the outer tube, institute
State outer tube and be provided with charging aperture, the first section of the thread segment of the threaded rod is near the connection end of the threaded rod, the threaded rod
Thread segment rear near the threaded rod discharge end, the stage casing of the thread segment of the threaded rod is located at the first section and institute
State between rear, the charging aperture on the outer tube is located in the first section region of the thread segment of the threaded rod, the screw thread
The width of the screw thread annular groove in the stage casing of the thread segment of bar less than the first section screw thread annular groove width, on the outer tube with it is described
The corresponding barrel in stage casing of the thread segment of threaded rod is provided with steam and portals.
In said structure, the width of the screw thread annular groove of first section is consistent with the threaded collar well width of conventional threads bar, so entering
After material speed is identical, but raw material enters stage casing, as the width of screw thread annular groove shoals, so raw material can be reinforced extruding, so as to
Raw material is made to generate heat because of high-pressure extrusion, the heat makes the moisture evaporation in raw material form steam and portal outside discharge by steam
Cylinder, so as to reach the purpose for evaporating raw material moisture.As the screw thread annular groove in stage casing shoals, raw material deal is constant, so raw material
More kinetic energy can be consumed during by the screw thread annular groove in stage casing, so, consume between the two factors in evaporation moisture and kinetic energy
Need to find an equilibrium point, to realize structure optimization, and the length and original position in stage casing is determined with this.
Preferably, the width of the screw thread annular groove in the stage casing of the thread segment of the threaded rod is the screw thread annular groove of the first section
2nd/to three/3rd of width；More preferably 1/2nd.
Preferably, the steam portals for multiple and be uniformly distributed on the outer tube and the thread segment of the threaded rod
On the corresponding barrel in stage casing.
Further, the steam portals for radial direction through hole.This simple structure, is easy to processing, if necessary to steam is drawn
To the two ends of outer tube, then the steam of " L " shape can be adopted to portal.
The beneficial effects of the utility model are：
This utility model arranges screw thread annular groove of the width less than first section by the stage casing of the thread segment in threaded rod, makes this spiral shell
Bar barrel has the function of evaporation raw material moisture, such that it is able to save the flow process of raw material stoving, has saved and has deposited because of raw material stoving
Drying plant cost and drying time human cost, and the structure change of this screw cylinder is little, it is easy to process, it is only necessary to
It is appropriate to increase power source, it is adapted to popularize.
Description of the drawings
Fig. 1 is the axial cross section structure diagram of new screw barrel described in the utility model, and discharge end is eliminated in figure
A part.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, new screw barrel described in the utility model includes outer tube 5 and threaded rod 2, threaded rod 2 is through outside
The central through hole of cylinder 5, outer tube 5 is provided with charging aperture 3, the first section 4 of the thread segment of threaded rod 2 near the connection end 1 of threaded rod 2,
Discharge end 9 of the rear 8 of the thread segment of threaded rod 2 near threaded rod 2, the stage casing 6 of the thread segment of threaded rod 2 be located at first section 4 with
Between rear 8, the charging aperture 3 on outer tube 5 is located in 4 region of first section of the thread segment of threaded rod 2, the screw thread of threaded rod 2
The width of the screw thread annular groove 61 in the stage casing 6 of section for the width of the screw thread annular groove 41 of first section 4 2/1sts to three/3rd, preferably
For 1/2nd, on outer tube 5, multiple through-hole structures are uniformly provided with the 6 corresponding barrel of stage casing of the thread segment of threaded rod 2
The steam of radial direction portals 7.
As shown in figure 1, the operation principle of new screw barrel described in the utility model is as follows：
Raw material (plastics) is entered in outer tube 5 from charging aperture 3, sequentially passes through first section 4,6 and of stage casing of the thread segment of threaded rod 2
Rear 8, and discharge from discharge end 9, granule is cut into using particle cutting tool during discharge, realize the purpose of raw material granulation.In this process
In, after raw material enters the screw thread annular groove 61 in stage casing 6, as the width of the screw thread annular groove 61 in stage casing 6 shoals, so raw material can be added
Strong to extrude, so that raw material generates heat because of high-pressure extrusion, the heat makes the moisture evaporation in raw material form steam and by steam
Portal 7 discharge outer tube 5, so as to reach the purpose for evaporating raw material moisture.
With reference to Fig. 1, the concrete structure of this screw cylinder can also have following supplement or deformation：
1st, steam portal the outer tube 5 on the inside of 7 inwall on filter screen is set, the filter screen can discharge steam while can stop
Raw material portals interior into steam；Or portal in steam filter plug, its function and above-mentioned filter screen are installed near the position of inner port in 7
It is identical.So may insure raw material will not into steam portal in result in blockage.
2nd, the rear 8 of the thread segment of threaded rod 2 can using with 6 identical structure of stage casing, i.e. the screw thread annular groove 81 of rear 8
Width it is identical with the width of the screw thread annular groove 61 in stage casing 6, can so increase evaporation raw material moisture length, make raw material drying
It is more thorough；Or, the rear 8 of the thread segment of threaded rod 2 is identical with the structure of first section 4, is so easy to discharge raw material；Or,
Screw thread annular groove 41 and the threaded collar in stage casing 6 of the width of the screw thread annular groove 81 of the rear 8 of the thread segment of threaded rod 2 between first section 4
Between the width of groove 61；Or, the width of the screw thread annular groove 81 of the rear 8 of the thread segment of threaded rod 2 is to narrow or by narrow by width
To the structure of wide even variation.These changes can according to the actual requirements depending on, and different production purposes can be realized.
Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model
System, as long as the technical scheme that can be realized on the basis of above-described embodiment without creative work, is regarded as falling into
In the rights protection scope of this utility model patent.
