Description
Technical field
The utility model relates to a kind of improvement of double screw extruder inventions, in particular to be for processing modified
The extrusion device of the double screw extruder of plastics.
Background technique
Modified plastics has the characteristics that fire-retardant, anti-impact, high tenacity, is widely used in household electrical appliances, computer, electric tool and object for appreciation
The industries such as tool, market demand rapid growth.Existing modified plastics is machined using Screw Extrusion, because modified plastics is using a variety of
Materiel machining, material interacts in whipping process can generate the impurity such as material moisture, microorganism, if excluding not in time,
Or exclude to be not thorough, then it will affect the quality of modified plastics.
Summary of the invention
In view of background technique, the technical problem to be solved by the present invention is to provide a kind of exclusion objects
Material impurity and the double screw extruder for improving product quality.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize: this kind of twin-screw
Extrusion device, includes barrel, twin-screw and extrusion die, and the barrel has material extrusion channel, is provided with and adds on the barrel
Hot device, the twin-screw are arranged in material extrusion channel, and one end of the twin-screw is connect with power source, the twin-screw it is another
End is connect with extrusion die, it is characterised in that feed inlet, auxiliary feed ports and auxiliary agent feed inlet are successively offered on the barrel,
The feed inlet is connect with charging basket, and the auxiliary feed ports are connect with auxiliary charging basket, and the auxiliary agent feed inlet and auxiliary agent charging basket connect
It connects, offers exhaust outlet beside the auxiliary agent feed inlet, the top of the exhaust outlet is equipped with exhaust blower, the exhaust blower and logical
Air piping connection, the extruding end of the twin-screw offer vaccum exhaust outlet, and the vaccum exhaust outlet is connected with vacuum pump.
Be provided with temperature sensor on the extrusion die, the temperature sensor, power source and heater with control
Device connection.
The gaseous impurities generated in material stirring extrusion process is tentatively discharged by exhaust outlet for the utility model, then again
By vaccum exhaust outlet, remaining impurity is discharged by vacuum pump, feed purity is improved, to improve extrusion plastic
Quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The working principle and its related details of the utility model are further described with reference to the accompanying drawing.This kind of twin-screw extrusion
Device, includes barrel 6, twin-screw, extrusion die and controller, and the barrel has material extrusion channel, is arranged on the barrel
Having heaters, the twin-screw are arranged in material extrusion channel, and one end of the twin-screw is connect with power source 1, the power source
The other end for driving motor, the twin-screw is connect with extrusion die, and temperature sensor, institute are provided on the extrusion die
It states driving motor, temperature sensor and heater to connect with controller, the temperature information of acquisition is sent to by temperature sensor
Controller is controlled the operation of heater and driving motor, by controller to improve product quality；It is successively opened up on the barrel 6
Have feed inlet 2, auxiliary feed ports 3 and auxiliary agent feed inlet 4, the feed inlet 2 is connect with charging basket 8, the auxiliary feed ports 3 with it is auxiliary
Charging basket 9 is helped to connect, the auxiliary agent feed inlet 4 is connect with auxiliary agent charging basket 10, offers exhaust outlet beside the auxiliary agent feed inlet
5, the top of the exhaust outlet is equipped with exhaust blower, and the exhaust blower is connect with ventilation shaft 11, and material is in stirring, extrusion process
The impurity such as moisture, microorganism can be generated, are tentatively excluded impurity by exhaust outlet, the extruding end of the twin-screw offers
Vaccum exhaust outlet 7, the vaccum exhaust outlet are connected with vacuum pump, i.e. vacuum pump passes through snorkel 13 and vacuum evacuation
Mouth connection, remaining impurity are discharged by vaccum exhaust outlet, so raising feed purity, and then guarantee the quality of moulding plastics.
When the utility model is processed, setting material squeezes out required temperature, and heater starts driving motor 1, double spiral shells
Bar rotation, material enter material extrusion channel by charging basket 8, and material is fed forward and is squeezed by twin-screw, and then supplies are by assisting
Charging basket 9 enters material extrusion channel, and supplies and material stir through twin-screw and continue to be fed forward, and is eventually adding auxiliary agent, material,
Supplies and auxiliary agent are stirred through twin-screw, are squeezed and melt, and are reacted to each other and are generated the impurity such as moisture and microorganism, exhaust blower makes
Barrel 6 is discharged by exhaust outlet 5 in impurity, and outdoor is discharged by ventilation shaft 11, avoids influencing processing environment, material is through preliminary
After waste discharge, then by vacuum waste discharge, i.e. vacuum suction pump startup, by the residual impurity in material extrusion channel by vacuum pump from true
Idle discharge port 7 is extracted out, is discharged by snorkel 13, and material continues to be fed forward, and the material after fusing is squeezed out by extrusion die,
Continuous moulding plastics are formed, the temperature sensor on extrusion die will test temperature information and be sent to controller, controller
By the information compared with the information of setting, if the temperature that the temperature of detection is higher than setting is stopped then sending instructions to heater
It only heats, if the temperature of detection is lower than the temperature of setting, then sending instructions to heater, heater continues to heat, so
Guarantee extrusion die normal operation.
