Description
Technical field
The utility model belongs to plastic granulator technical field, specifically a kind of modeling of hard powder and plastic blend
Expect extrusion screw rod barrel configuration.
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.
Currently, the screw rod in the screw extruder being currently being used on the market is mostly spiral lamination structure, for hard powder
The raw material at end and plastic blend in production process, will produce abrasion between machine barrel, screw rod and raw material, can by machine barrel or
Galling on person's screw rod is fallen so that is worn the metal fragment to get off and is mixed into raw material, influence product quality, causes to produce
Product are unqualified.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of plastic extruding screws of hard powder and plastic blend
Barrel configuration is not easy to generate abrasion to machine barrel and screw rod, ensures product matter for the raw material of hard powder and plastic blend
Amount.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of plastic extruding screw barrel configuration of hard powder and plastic blend, including machine barrel and the spiral shell that is located in machine barrel
Bar, the tail end that screw rod is corresponded on the machine barrel are equipped with hard powder addition mouth, and the outer surface of screw rod sprays meltallizing tungsten steel alloy shape
At tungsten steel alloy layer, machine barrel includes tungsten steel alloy liner and nitridation steel sleeve, and tungsten steel alloy liner is close in nitridation steel sleeve
The tail end on surface, screw rod is installed with screw mixing section, and the die head of screw front end is equipped with stainless steel outer sleeve.
The screw mixing section is located at the rear of hard powder addition mouth.
The nitridation steel sleeve is made of 38CrMoAlA materials.
The hard powder addition mouth is equipped with towards the inclined beveled region of screw mixing section.
The stainless steel outer sleeve being arranged on the die head is 304 stainless steel outer sleeves.
The utility model is not easy to generate abrasion to machine barrel and screw rod, protect for the raw material of hard powder and plastic blend
Product quality is demonstrate,proved, the processing of the raw material of superhard powder and plastic blend is especially suitable for.
Description of the drawings
Attached drawing 1 is the utility model part section structural representation；
Attached drawing 2 is enlarged diagram at the A in attached drawing 1.
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 figure 1 and 2, the plastic extruding screw barrel configuration of a kind of hard powder and plastic blend, including machine barrel
With the screw rod 1 being located in machine barrel, the tail end that screw rod 1 is corresponded on the machine barrel is equipped with hard powder addition mouth 5, the appearance of screw rod 1
Face sprays meltallizing tungsten steel alloy and forms tungsten steel alloy layer 8, and machine barrel includes tungsten steel alloy liner 7 and nitridation steel sleeve 6, tungsten steel alloy
Liner 7 is close to nitridation 6 inner surface of steel sleeve, and the tail end of screw rod 1 is installed with screw mixing section 3, carries out mixing production, screw rod 1
The die head of front end is equipped with stainless steel outer sleeve 2.By the tungsten that wear-resisting tungsten steel alloy layer and high abrasion are arranged in screw rod outer surface
Steel alloy liner, for hard powder, especially superhard powder will not form abrasion, to really to machine barrel and screw rod outer surface
It protects no metal fragment to be blended in dusty material, ensures product quality.
The screw mixing section is located at the rear of hard powder addition mouth.
The nitridation steel sleeve is made of 38CrMoAlA materials.
The hard powder addition mouth 5 is equipped with towards 3 inclined beveled region 4 of screw mixing section, is flowed to convenient for hard powder
Screw mixing section.
The stainless steel outer sleeve being arranged on the die head is 304 stainless steel outer sleeves.
In the utility model, the structure that machine barrel is set as being made of two kinds of metals is set as with the inner surface that screw rod faces
Tungsten steel alloy liner, and outside is wrapped to form nitridation steel sleeve using 38CrMoAlA materials so that the surface of machine barrel forms wear-resisting
Damage structure.In hard powder and plastic blend production, hard powder is contacted with the tungsten steel alloy liner of machine barrel, is not easy to machine barrel
Inner surface generates abrasion, while screw surface is also tungsten steel alloy layer, has high-wearing feature, thus in entire production process not
Metal fragment can be formed to be mixed into raw material, ensure that the quality of product, be especially suitable for hard powder or superhard powder and modeling
The blending of material produces.
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.
