Be not easy during the grinding process stuck, and grinding effect is preferable, is provided simultaneously with degassing function, and it is husky to reduce the attachment of extruded stock surface
Son and bubble, improve the quality of extruded stock.
Since there are various impurity for various raw materials, so that the quality of component, temperature, pressure are different in raw material, tradition is drawn
Row plasticizing extrusion, production technology are complicated and cumbersome again after silk machine needs to be filtered the impurity in raw material.And the present invention proposes
Automatic fast quick change strainer exhaust dual stage plastic extruder in the way of plain grinding to each component in raw material carry out plasticizing squeeze
Out, the grinding of plain grinding mode is more abundant, can provide the room and time of temperature conduction to each component during the grinding process,
When gas is reversely discharged, temperature conduction is carried out between each component, so that the quality for the extruded stock that final plasticizing squeezes out
It tends towards stability, and does not need to be filtered removal to the impurity in raw material in advance again, saved raw material and improved extruded stock

It must just be replaced when spending, the host for including of traditional wire drawing machine and multiple slaves are mounted on strainer, and mounting means is equal
To be bolted.In actual production, it is often necessary to replace the strainer in host and slave, reason is two o'clock: first is that raw material
In containing there are many waste material and impurity, the host of traditional wire drawing machine is after filtering out a portion impurity, and remaining impurity is still
The strainer in subsequent slave is needed to be filtered, filter pressure is still larger；Second is that raw material not pass through by homogeneity and plurality of impurities
The effect of traditional twin-screw grinding plasticizing is poor, and the impurity in many raw materials is unable to get sufficiently plasticizing and melting, causes to lead
The extruded stock yield that machine finally obtains is lower, and waste material and waste silk yield are higher, and strainer needs the impurity level filtered to greatly improve.
To solve the above-mentioned problems, the exhaust screw that the present invention is correspondingly arranged can sufficiently solve the above problems.Host
The filter pressure of strainer is larger, but the filter pressure of subsequent slave greatly reduces.Therefore, the present invention is only needed in certain time
Interior replacement host strainer, slave strainer are greatly prolonged using the time.
But in the actual production process, there are the mistakes that host replaces strainer there is still a need for the time of 20-30s
