Description
Technical field
The utility model is related to powder coating technology field, and in particular to a kind of powdery paints it is special there is multi-angle
The screw rod of spiral shell block.
Background technology
Screw rod, outer surface cut with the cylinder of helicla flute or cut with the circular cone of Conical Spiral Groove.Screw rod has different heads,
As the head in picture is outer-hexagonal screw rod.Also other, such as big flat screw rod, hexagon socket head cap screw etc..
The length of screw rod, typically without absolute growth, and weighed with the length of relative what diameter.So, different-diameter
Screw rod also may compare length.This length is represented draw ratio with L/D.Spiro rod length only calculates threaded part certainly.More
Accurate algorithm is the center line calculated to hopper, referred to as effective length or effective L D ratio.
But when processing powdery paints using common screw, frequently encounter coating and be largely attached on screw rod outer wall, seriously
Extruder normal use is influenceed, adds production cost, this problems demand solves.
The content of the invention
For the deficiencies in the prior art, the purpose of this utility model be to provide it is a kind of rational in infrastructure, it is easy to use
A kind of special screw rod with multi-angle spiral shell block of powdery paints, it solves these above-mentioned problems.
Technical scheme is as follows used by the utility model：A kind of special spiral shell with multi-angle spiral shell block of powdery paints
Bar, including screw body, described screw body one end are feeding side, and the other end is output end, between feeding side and output end
For spiral shell rib portion, the spiral shell rib portion is collectively constituted by some spiral shell ribs and spiral shell block, and the part of the spiral shell rib portion connection feeding side is feeding
Portion, the feeding portion connect fusing department, and the fusing department connects the first series-parallel connection area, and the spiral shell block in the first series-parallel connection area is mixed for 30 °
Join block, the first series-parallel connection area connects the second series-parallel connection area, and the spiral shell block in the second series-parallel connection area is 45 ° of series-parallel connection blocks, and described second is mixed
Join area and connect the 3rd series-parallel connection area, the 3rd series-parallel connection area is 60 ° of series-parallel connection blocks, and the 3rd series-parallel connection area connects the 4th series-parallel connection area, institute
It is 90 ° of series-parallel connection blocks to state the 4th series-parallel connection area.
Preferably, the length of screw rod is 1-20 rice.
The beneficial effects of the utility model include：
Screw rod spiral shell block angle of the present utility model typically points 30,45,60,90 4 kind, angle is bigger, and resistance is bigger, especially suitable
Together in the production and processing of powdery paints, thick series-parallel connection, thin series-parallel connection, ultra-fine series-parallel connection are carried out to coating raw material respectively, series-parallel connection precision is obvious
Improve, not only increase yield rate, also to processing efficiency, prevent from solidifying, prevent from being charred etc. and have many advantages, such as.
Brief description of the drawings
Fig. 1 is a kind of special screw rod overall structure diagram with multi-angle spiral shell block of powdery paints of the utility model.
Embodiment
The utility model is described in detail with reference to embodiment.
A kind of special screw rod with multi-angle spiral shell block of powdery paints, including screw body, described screw body one end
For feeding side 1, the other end is output end 2, is spiral shell rib portion between feeding side 1 and output end 2, the spiral shell rib portion is by some spiral shell ribs
Collectively constituted with spiral shell block, the part of the spiral shell rib portion connection feeding side is feeding portion 3, and the feeding portion 3 connects fusing department 4, institute
State fusing department 4 and connect the first series-parallel connection area 5, the spiral shell block in the first series-parallel connection area 5 is 30 ° of series-parallel connection blocks, and the first series-parallel connection area 5 connects
Second series-parallel connection area 6, the spiral shell block in the second series-parallel connection area 6 is 45 ° of series-parallel connection blocks, and the second series-parallel connection area 6 connects the 3rd series-parallel connection area 7,
The 3rd series-parallel connection area 7 is 60 ° of series-parallel connection blocks, and the 3rd series-parallel connection area 7 connects the 4th series-parallel connection area 8, and the 4th series-parallel connection area 8 is
90 ° of series-parallel connection blocks.
Preferably, the length of screw rod is 1-20 rice.
Principle is as follows, and screw rod is usually used in reciprocating damp type screw extruder, and the inside of extruder sleeve has some rows to mix
Dowel pin is followed closely, and these pins protrude in sleeve lining, screw rod front-rear reciprocation movement while rotation, and the mixing inside barrel
The spiral shell rib of pin and screw rod forms relative motion, and its result makes a boring part, because the effect of each pin is usually returned
To original position, boring just to be conveyed out coming along circuit, mixing pin ring here just each serves as high speed shear
The effect of power mixer, good mixed effect is obtained within the shorter holdup time.
The immixture of reciprocating damp type screw extruder, inherently a series of Kneeding stirrers of pin are mixed, by
The material of screw rod transmission is mixed, and because the relative motion of sleeve and screw rod produces shearing force, completes production.
Screw rod of the present utility model coordinates reciprocating damp type screw extruder, is particularly suitable for producing powdery paints, especially
It is the powdery paints containing flakey raw material in dispensing, can accomplishes to prevent from solidifying, prevent from being charred.
Above-mentioned embodiment is preferred embodiment of the present utility model, is not for limiting implementation of the present utility model
The equivalence changes made with interest field, all contents according to described in present utility model application scope of patent protection and modification,
It all should be included in present utility model application the scope of the claims.
