Wherein mixing extruder set mixing is integrated with extrusion function, similar to this patent function, but its structure On have the following deficiencies:

(1) its direction of motion that set rotary screw is mixed is single, this will lead to mixing unevenly, stirring Of poor quality, when material passes through discharge port, the extrusion pressure of discharge port is excessive, be easy to cause mold core abrasion to accelerate, is unfavorable for It uses.

(2) its screw pitch that set rotary screw is mixed is single, so that on screw rod on the screw rod of adjacent screw pitch Equalization of pressure of the material when being squeezed out, if should during occur above-mentioned mixing it is uneven when, squeezing out Most probably there is mismachining tolerance in the material squeezed out in journey, material precision phenomenon not up to standard, therefore in order to prevent since material mixes Unevenly cause material to squeeze out phenomenon not up to standard, increases the extrusion pressure of mixing extruder end, so that material is being pressurized Power, which is slightly larger than, voluntarily to be mixed and is extruded in the state of the material pressure of screw rod front.

Secondly, mixing extruder type is also many at present, but the mixing extruder for mixing and squeezing out suitable for feed is very Few, current feed is generally left with after tentatively mix into feed bin, takes from feed bin after will pass through the material tentatively mixed It out and is placed in extruder and is further processed, there are 2 defects for process traditional in this way:

(1) above-mentioned mixing and squeeze out 2 processes interruption and carry out, during which material can because being exposed in air in short term, Texture is hardened, density becomes smaller, and output quality is unqualified.

(2) and mixing extruder is mainly used for the equipment for mixing granular material with liquid in feed, squeezing out；It is existing Mixing machine mainly pass through mixing component and stir powder raw material, the material that moisture content is high, viscosity is high can not be adapted to, therefore made It is also very necessary to obtain the material that mixing extruder can be high suitable for viscosity.

Therefore it can either complete to carry out material well there is presently no a kind of mixing extruder suitable for feed processing It is adequately mixed, and material uniformly can be subjected to extrusion operation.
