Description
Technical field
The utility model relates to a kind of three screw rod high pressure extruders, belongs to plastics machinery field.
Background technology
Extruder can be divided into extruding continuously with discontinuous by type of action to be extruded, and extruder is the important machine of processing plastic product.According to the difference of pressuring method kind, expressing technique can be divided into and extrude continuously and intermittently extrude two kinds, the former equipment used is screw-type extruder, the latter's equipment is plunger-type extruder.The working mechanism of screw-type extruder is pressure and the shearing force that relies on screw rod rotation to produce, and can make material fully to plastify and evenly mix, by mouth mold forming; So sometimes use an extruder just can complete mixing simultaneously, the series of process such as plasticizing and moulding, thus carry out continuous production; Yet be subject to the characteristic requirements of some specialities, need under high pressure conditions, extrude, and common screw extruder cannot reach high pressure, so this be urgent problem.
Summary of the invention
The purpose of this utility model is to provide a kind of three screw rod high pressure extruders.
Problem to be solved in the utility model is the defect that existing common extruder cannot high pressure be extruded.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of three screw rod high pressure extruders, comprise base, motor, gear-box, charging aperture, hopper, machine barrel a, sub-screw, machine barrel b, driving screw, die head and bracing frame, described motor and gear-box are arranged on base, motor rotary shaft is connected with gear-box, machine barrel a is mounted on gear-box body by flange, machine barrel b is fixed on base by bracing frame, and machine barrel b and machine barrel a are bolted; Driving screw has one, driving screw is arranged in machine barrel a and machine barrel b, driving screw shank is connected with gear-box, sub-screw has two, two sub-screws are arranged in machine barrel a and mesh with driving screw respectively, sub-screw shank is connected with gear-box, and motor drives two sub-screws and a driving screw to rotate by the conduction of gear-box simultaneously; Machine barrel a is provided with a charging aperture, and hopper is installed on charging aperture, and raw material enters in machine barrel a from hopper, and die head is arranged on machine barrel b afterbody, and machine barrel a and machine barrel b outer surface are provided with electric heater unit.
The utility model has the advantages that: because sub-screw has two, and mesh with driving screw respectively, therefore there are two region of engagements, can make material more fully to plastify and evenly mix; There are three screw rods in machine barrel a district, and machine barrel b district is a surplus screw rod only, so machine barrel a district internal volume is greater than machine barrel b district, in machine barrel b district, will form higher-pressure region, and high pressure is just extruded can process special plastic product.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of three screw rod high pressure extruders of the utility model;
Fig. 2 is A-A cutaway view of a kind of three screw rod high pressure extruders of the utility model;
In figure: 1, base 2, motor 3, gear-box 4, charging aperture 5, hopper 6, machine barrel a 7, sub-screw 8, machine barrel b 9, driving screw 10, die head 11, bracing frame.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
A kind of three screw rod high pressure extruders, comprise base 1, motor 2, gear-box 3, charging aperture 4, hopper 5, machine barrel a6, sub-screw 7, machine barrel b8, driving screw 9, die head 10 and bracing frame 11, described motor 2 and gear-box 3 are arranged on base 1, motor 2 rotating shafts are connected with gear-box 3, machine barrel a6 is mounted on gear-box 3 bodies by flange, machine barrel b8 is fixed on base 1 by bracing frame 11, and machine barrel b8 and machine barrel a6 are bolted; Driving screw 9 has one, driving screw 9 is arranged in machine barrel a6 and machine barrel b8, driving screw 9 shanks are connected with gear-box 3, sub-screw 7 has two, two sub-screws 7 are arranged in machine barrel a6 and mesh with driving screw 9 respectively, therefore form two region of engagements, can make material more fully to plastify and evenly mix; Sub-screw 7 shanks are connected with gear-box 3, and motor 2 drives two sub-screws 7 and a driving screw 9 to rotate by the conduction of gear-box 3 simultaneously; Machine barrel a6 is provided with a charging aperture 4, and hopper 5 is installed on charging aperture 4, and raw material enters in machine barrel a6 from hopper 5, and die head 10 is arranged on machine barrel b8 afterbody, can moulding plastics finished product by die head 10, and machine barrel a6 and machine barrel b8 outer surface are provided with electric heater unit.
The utility model using method: the electric heater unit of first opening machine barrel a6 and machine barrel b8 outer wall, when temperature reaches setting value, raw material is poured in hopper 5, actuating motor 2, driving screw 9 and two sub-screws 7 rotate simultaneously, and two sub-screws 7 mesh with driving screw 9 respectively, therefore form two region of engagements, can make material more fully to plastify and evenly mix, by screw rod and machine barrel effect, finally from 10 of the die heads product of high-quality out.
