Description
Technical field
The utility model belongs to field of plastics processing, and in particular to a kind of packing material production extruder element high.
Background technology
In field of plastics processing, the screw rod of extruder is the critical elements in extruder, by its rotation, in barrel
Plastics could be moved, and be pressurized and heat, therefore the range of application and productivity ratio of extruder both depend on the structure of screw rod.Squeeze
Go out machine to be modified material, it is most important that being sufficiently mixed and plastifying to various materials, packing material high is due to processing raw material
Characteristic, it is necessary to increase screw rod feeding ability, while to extend residence time of the material in machine barrel, improve screw rod to material
Mixed, could cause that material is sufficiently mixed plasticizing, enhance product performance.
At present, it always is for the processing of packing material high relatively difficult.If using traditional parallel double-screw
Extrusion equipment is processed, it may appear that investment is big, energy consumption is big, yield poorly and mix uneven shortcoming.If using the country
The conical double screw extruder of outer most of manufacturer productions, once filling packing material high, the quality of obtained finished product is excessively poor,
And yield is very low.
In sum, height cannot all be met using traditional parallel double-screw extrusion equipment or conical double screw extruder
The production requirement of packing material, therefore, it is badly in need of a kind of extruder element suitable for packing material high production of design.
Utility model content
The purpose of this utility model is to solve problem present in above-mentioned prior art, there is provided a kind of packing material life high
Extruder element is produced, is adapted to the blending production of filling high (filling proportion is higher than 40%) material, and yield can be improved.
The utility model is achieved through the following technical solutions：
A kind of packing material high production extruder element, it is single screw rod structure, including material input section, mixed melting section
With finished product deferent segment；
The material input section is conical structure, and big pitch spiral shell is provided with the outer surface of the material input section
Line；
The mixed melting section is conical structure, and it is connected to form continuous conical structure with material input section；
The thread edge of the mixed melting section is provided with backflash；
The finished product deferent segment is cylindrical structure, is provided with tapered screw in periphery.
Preferably, the taper of the material input section and mixed melting section is 5-15 degree.
Preferably, the steep-pitch thread account for the axial overall length of whole screw-rod structure 10 to ten/15th/
One.
Preferably, mixed melting section account for the axial overall length of whole screw-rod structure 80 to ten/15ths/
Seven.
Preferably, the material input section, the screw thread of mixed melting section are used with tapered screw.
Preferably, the cross section of the backflash of the mixed melting section is U-shaped.
Preferably, the taper of the screw of the finished product deferent segment is 15-30 degree.
Compared with prior art, the beneficial effects of the utility model are：The utility model uses the extruder of special construction
Screw mixes element, be adapted to the blending production of filling high (filling proportion is higher than 40%) material, it is to avoid a large amount of solid accumulations, mixes
Close effect good, and improve yield.
Brief description of the drawings
Fig. 1 the utility model packing material high produces the structural representation of extruder element；
The schematic diagram of the U-type groove on Fig. 2 the utility model packing material production extruder element high.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
It is single screw rod structure as shown in figure 1, a kind of packing material high production extruder element, including material input section 1,
Mixed melting section 2 and finished product deferent segment 3；The material input section 1 is conical structure, in the appearance of the material input section 1
Steep-pitch thread 5 is provided with face, conical structure ensure that material continuously and smoothly enters in machine barrel, steep-pitch thread 5
The rate of feeding of screw rod is accelerated, production efficiency is improve.Specifically, the material input section 1 accounts for whole screw-rod structure
/ 10th to ten/5th of axial overall length.
The mixed melting section 2 is conical structure, and it is connected to form continuous conical structure with material input section；Institute
The taper preferably 5-15 degree of material input section and mixed melting section is stated, is so conducive to the continuous and stable of material to enter.
Backflash is provided with the thread edge of mixed melting section 2, raw material can back and forth flow in mixed melting section, make
Obtain material to be sufficiently mixed uniformly, improve the quality of production of finished product.It is U-shaped structure, such as Fig. 2 that the backflash uses cross section
It is shown.
The finished product deferent segment 3 is cylindrical structure, is provided with tapered screw 4 in periphery, described
The taper of screw 4 is 15-30 degree, and the material input section, the screw thread of mixed melting section can use conventional tooth form,
Can use with tapered screw, after with tapered screw, be more beneficial for the discharge of material, prevent thing
Material is piled up in the machine barrel of extruder.
Operation principle of the present utility model is as follows：Feed opening of the material from extruder barrel enters material input section,
Under motor drives, screw rod rotation, in mixed melting section, continuously and smoothly mixed melting completes plasticizing to material, eventually passes finished product defeated
Machine barrel is exported after going out section.
Above-mentioned technical proposal is a kind of implementation method of the present utility model, for those skilled in the art,
On the basis of the utility model discloses principle, it is easy to make various types of improvement or deformation, be not limited solely to this reality
It is with the structure described by new above-mentioned specific embodiment therefore previously described simply preferred, and it is not restrictive
Meaning.
