Abstract
The invention discloses one kind segmentation fluting machine barrel.Including feeding section, melt zone, metering section；The feeding section is provided with four-head left hand thread groove, identical with the direction that material advances, and shear stress is formed between material for material Fast Compression to be formed in helical form, with screw channel；The melt zone is provided with 16 roads semicircle longitudinal groove, different from the direction that material advances, and for cutting the material being embedded into semicircle longitudinal groove, forms the friction between material and material；The metering section is provided with a left-turn spiral groove, for upsetting vortex of the fused materials in machine barrel, improves the uniformity of mixed effect and Temperature Distribution.The present invention has the advantages that conveying power is strong, plasticizing capacity is high, good mixing effect, uniformity of temperature profile.
Description
Technical field：
The invention belongs to screw extruder component technology field, more particularly to a kind of segmentation fluting machine barrel.
Background technology：
Conventional extruder typically uses smooth barrel, and the power that solid material is fed forward is between material and smooth barrel
Frictional force, this frictional force is smaller, have impact on production efficiency.Traditional smooth barrel extruder, the energy of material plasticizing is main
The heat transfer (in general the former plays a leading role) of friction and machine barrel between machine barrel and material, due to frictional force compared with
Small, input energy is less, reduces plasticizing capacity, have impact on production efficiency.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the invention, without answering
In being considered as recognizing or imply in any form that the information structure has been the prior art well known to persons skilled in the art.
The content of the invention：
It is an object of the invention to provide one kind segmentation fluting machine barrel, so as to overcome above-mentioned defect of the prior art.
To achieve the above object, the invention provides one kind segmentation fluting machine barrel, the segmentation fluting machine barrel includes charging
Section, melt zone, metering section；The feeding section is provided with four-head left hand thread groove, identical with the direction that material advances, for by thing
Material Fast Compression is formed in helical form, with screw channel and forms shear stress between material；It is semicircle that the melt zone is provided with 16 roads
Longitudinal groove, it is different from the direction that material advances, be embedded into material in semicircle longitudinal groove for cutting, formed material and
Friction between material；The metering section is provided with a left-turn spiral groove, for upsetting vortex of the fused materials in machine barrel,
Improve the uniformity of mixed effect and Temperature Distribution.
Compared with prior art, the present invention has the advantages that：
Material Fast Compression is formed in helical form, with screw channel and formed between material by the left hand thread groove of feeding section
Shear stress, enhances the power of material conveying.The semicircle longitudinal groove of melt zone is cut and is embedded into semicircle longitudinal groove
Material, form the friction between material and material, the frictional force much larger than the frictional force between material and machine barrel, so as to increased
Input energy, increased plasticizing capacity.The left-turn spiral groove of metering section upsets vortex of the fused materials in machine barrel, improves mixed
Close the uniformity of effect and Temperature Distribution.
Brief description of the drawings：
Fig. 1 is present invention segmentation fluting barrel configuration schematic diagram；
Reference is：The semicircle longitudinal direction ditch of 1- feeding sections, 2- melt zones, 3- metering sections, 4- left hand threads groove, 5-
Groove, 6- left-turn spiral grooves.
Specific embodiment：
Specific embodiment of the invention is described in detail below, it is to be understood that protection scope of the present invention is not
Limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
As shown in figure 1, a kind of segmentation fluting machine barrel, including feeding section 1, melt zone 2, metering section 3；The feeding section 1 is opened
There is four-head left hand thread groove 4, it is identical with the direction that material advances, for material Fast Compression to be formed into helical form, with screw rod
Shear stress is formed in screw channel between material, the power of material conveying is enhanced；The melt zone 2 is provided with the semicircle longitudinal direction ditch in 16 roads
Groove 5, it is different from the direction that material advances, for cutting the material being embedded into semicircle longitudinal groove 5, form material and material
Between friction, the frictional force, so as to increased input energy, increased plasticizing energy much larger than frictional force between material and machine barrel
Power；The metering section 3 is provided with a left-turn spiral groove 6, for upsetting vortex of the fused materials in machine barrel, improves mixing effect
Really with the uniformity of Temperature Distribution.
The purpose of selecting and describing the exemplary embodiment is that explaining that certain principles of the invention and its reality should
With so that those skilled in the art can realize and using a variety of exemplaries of the invention and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
