Abstract
The utility model discloses a kind of low molecule environment-friendly degradable plastic granulating screw rods, including screw body, the screw surface is equipped with several continuous uninterrupted three lead screw, all threads are divided into several groups thread group, every group of thread group all includes several threads, the alveolus depth of thread in the thread group of two adjacent groups differs, and the thread in every group of thread group is set as arc.Mainly for low molecule environment-friendly degradable plastic processing, realization is smooth to be walked to expect the utility model, is ensured that production is continuous, is normally carried out.
Description
Technical field
The utility model belongs to Granulation Equipments technical field, and specifically one kind being mainly used for low molecule environment-friendly degradable
Plastic granulating screw rod.
Background technology
Plastic extruder belongs to one of type of plastic processing machinery, and screw extruder is the pressure generated by screw rod rotation
Power and shearing force can allow material fully to carry out plasticizing and uniformly mixing, be molded by mouth mold.Screw rod be extruder compared with
For important and crucial component, the quality and productivity of the plastic products of production all directly depend on machine melt extrusion temperature
Uniformity and pressure, the stability of extrusion capacity, and these parameters all directly depend on the structural behaviour of screw rod.
For different materials, the screw rod using different structure is needed.Contain in low molecule environment-friendly degradable plastic components
When using prilling, there is not feeding, do not walk to expect situation in the starch component of very high percentage, cause production that can not carry out.Tradition
Machinery can not extrusion.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of low molecule environment-friendly degradable plastic granulating screw rods, realize
It is smooth to walk to expect, ensure that production is continuous, normally carry out.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of low molecule environment-friendly degradable plastic granulating screw rod, including screw body, the screw surface are equipped with several
All threads are divided into several groups thread group by continuous uninterrupted three lead screw, and every group of thread group all includes several spiral shells
The alveolus depth of tooth, the thread in the thread group of two adjacent groups differs, and the thread in every group of thread group is set as arc.
The depth of the alveolus of thread in the same group of thread group is identical.
The depth of the alveolus of thread in the same group of thread group differs.
The descending gradual change of depth of thread in the same group of thread group.
The ascending gradual change of depth of thread in the same group of thread group.
The depth of thread in the same group of thread group is arbitrarily mutated.
Compression release exhaust outlet is additionally provided on the screw rod.
The utility model mainly for low molecule environment-friendly degradable plastic processing, realize it is smooth walks material, ensure production it is continuous,
Normally carry out.
Description of the drawings
Attached drawing 1 is the utility model main structure diagram.
Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
As shown in Fig. 1, the utility model discloses a kind of low molecule environment-friendly degradable plastic granulating screw rod, including screw rod
Main body 1, the screw surface are equipped with several continuous uninterrupted three lead screw 2, all threads are divided into several groups spiral shell
Tooth group, every group of thread group all include several threads, and the alveolus depth of the thread in the thread group of two adjacent groups differs, every group
Thread in thread group is set as arc.The root of thread is set as the arc at no dead angle.
The depth of the alveolus of thread in the same group of thread group is identical, for the thread group of the type, may be defined as
Deng deep thread group 3, the depth of each thread in such depth thread group 3 is identical.
Or the depth of the alveolus of the thread in the same group of thread group differs.Can be specifically same group of thread
The descending gradual change of depth of thread in group；Or the ascending gradual change of depth of the thread in same group of thread group.Belong to
In the depth gradation type of thread, either gradually increases or reduce from big to small from small to large, may be defined as gradual change thread group 4.
Or the depth of the thread in same group of thread group is arbitrarily mutated, you can mutation thread group 5 is defined as, at this
The depth for being mutated each thread in thread group is arbitrary mutation, random variation.
Can in any combination, for example deep thread group, gradual change thread group and the mutation thread such as be for two adjacent groups thread group
The alternate cycles secondary according to this of group.It the deep thread group such as can also be, be mutated the alternate cycles successively of thread group and gradual change thread group.Or
Person is other combinations, has no specific restriction.
Compression release exhaust outlet, the performance of lifting handle are additionally provided on the screw rod.
In the utility model, by carrying out above-mentioned restriction to screw rod, in the processing for low molecule environment-friendly degradable plastics
When, there is no because in material the presence of high proportion starch and the case where lead to not walk material, it is ensured that smooth feeding is realized steady
Determine, reliably produce.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
