Description
Technical field
The utility model relates to plastic products tool of production technical fields, and in particular to a kind of novel high-pressure is plasticized by force flat double
Screw barrel.
Background technique
Due to being all the screw rod using normal thread at present, i.e., a certain section of the screw thread trend in the active section segment length of screw rod
It is constant, especially in processing to be not easy to be plasticized POM, pp modified materials, PS etc. is more obvious when being main raw material(s), so
Its mixed receives certain influence, and also limits the application range of this screw extruder.
Since POM, PP modified materials, PS and calcium powder and various molecule material feedings are unstable, premature decomposition, current fluctuation is big.
The mixed molecules material such as material overheat, is plasticized too early: material being caused to be carbonized, so that prouctiveness reduces, especially produces plate, profile
When it is more obvious, generate jaundice after the booting of surface, black, internal layer generates decorative pattern and decomposition product, and generates toxic gas.
The spiral shell rib that our company changes screw rod on existing equipment moves towards depth, allows raw material and the more stable pump of filler
It send and melts, the spontaneous temperature of generation is lower, extends the material resolving time.
Especially our company is reducing inner hole using screw rod mutation section and machine barrel accordingly, turns material from concora crush state suddenly
For high pressure conditions, control reinforces pressure, reaches increase production capacity, further increase finished product rate to improve plasticizing.
Utility model content
The purpose of the utility model is to provide a kind of shortenings to find time, and improves yield, and diminution makes material and calcium powder and each
Kind of molecule material feeding is more stable, uniform novel high-pressure is plasticized by force flat double machine barrel screw rod.
To achieve the goals above, the utility model provides the following technical solutions:
A kind of novel high-pressure disclosed by the utility model is plasticized by force flat double machine barrel screw rod, comprising:
Barrel assembly is formed with screw rod chamber inside the barrel assembly；
Screw body, the quantity of the screw body are two, and it is intracavitary that two screw bodies are placed in the screw rod；
The flange assembled with the barrel assembly and screw body；
The screw bolt seat being formed in the middle part of the barrel assembly.
Further, the barrel assembly includes front barrel and rear machine barrel, and the front barrel and rear inside machine barrel are respectively formed
There is screw rod chamber.
Further, the flange is assemblied in the front end of the front barrel, and the flange and the front barrel screw thread connect
Connect fixation.
Further, the screw bolt seat is in split type structure comprising the fixed screw bolt seat of two assembly is seperated, Mei Gesuo
It states screw bolt seat fission and has been respectively formed on semicircle screw slot.
In the above-mentioned technical solutions, a kind of novel high-pressure provided by the utility model is plasticized by force flat double machine barrel screw rod, has
Below the utility model has the advantages that
The reasonable feed zone of the utility model screw rod band, shears mixing section, and plasticizing mutation section can eliminate material in screw rod
Portion's operation reaches ultimate attainment, makes the viscous flow state of user in process of production with oil circulation device, is not likely to produce poison gas, moulds too early
Change, avoid high temperature, high shear, high current, the available machine time is long.Therefore this screw rod can mold various rule under die pressure effect
Plate, the shape product of lattice complexity.
