Mix plastic grain and become molten state, be constantly extruded into through spiral propeller from head extrusion, it is circular ring shape to become section
Thin-walled cylinder section bar, cooling sizing is carried out subsequently into vacuum sizing box.The structure is for round plastic pipe vacuum sizing effect
It is good, but for square pipe, if head extrusion mouth is changed into it is square, vacuum sizing pipe also directly change into it is square, due to side
Shape structure, there are point effect, in vacuum sizing pipe cooling procedure, is usually present inhomogeneous cooling phenomenon, life there are four right angles
The rectangular area of the square pipe of output and non-straight angular zone cooling effect differ, and ultimately cause square plastic pipe structure office
Portion's deformation is serious, poor product quality.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of vacuum sizing box of square plastic expects pipe.
The technical solution adopted in the utility model is as follows：
A kind of vacuum sizing box of square plastic expects pipe, includes the babinet of vacuum sizing box, is provided with calibration sleeve in babinet, institute
State and cavity is left between babinet and calibration sleeve, which is vacuum chamber, and the water inlet and pumping of connection vacuum chamber are provided with babinet
Mouth is pressed, the internal cavities of the calibration sleeve are sizing chamber, and the sizing chamber is diameter-changing cavity.
Further, one end of the diameter-changing cavity be circular ring shape, the other end be square.
Further, the fillet surface that the both ends of the diameter-changing cavity are gradually changed by radius of curvature links up.The mistake
The radius of curvature for crossing curved surface becomes larger from square end to circular ring shape end.
Further, the streamlined curved surface of the fillet surface.
Further, the tank ends are provided with flange end cap and soft diaphragm seal, and the internal diameter of the diaphragm seal
Less than the internal diameter of calibration sleeve.
Further, straggly on the calibration sleeve to be evenly equipped with multiple vacuum ports, the shape of the vacuum port is circular, strip
One or both of shape.
Further, the water inlet is located at the lower end of the babinet, and the pumping pressure mouth is located at the upper end of the babinet.
Compared with prior art, the utility model has following innovative point：
The vacuum sizing box of square plastic expects pipe described in the utility model, sizing chamber are diameter-changing cavities, and modeling material pipe Pei is carried out
Sizing, since fillet surface is flowing transition curved surface, so being smooth square in surface in the plastic tube that square calibre comes out
Pipe.The vacuum sizing box of square plastic expects pipe described in the utility model, can be timely and effectively to pipe between extruder and water tank
Material carries out sizing processing, and structure square shaped tubing cooling sizing is uniform, and obtained square pipe surface is smooth, product quality
Height, and the vacuum sizing box of square plastic expects pipe described in the utility model is simple in structure, cost is low, wide market.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the outline structural diagram of the vacuum sizing box of square plastic expects pipe described in the utility model；
Fig. 2 is the outline structural diagram of the vacuum sizing box of square plastic expects pipe described in the utility model；
Fig. 3 is the left view of the vacuum sizing box of square plastic expects pipe described in the utility model.
Embodiment
The detailed content and its embodiment of the utility model are further illustrated below in conjunction with the accompanying drawings.
Embodiment 1
A kind of vacuum sizing box of square plastic expects pipe, as shown in Figs. 1-3, includes the babinet of vacuum sizing box, is set in babinet
Calibration sleeve is equipped with, cavity is left between the babinet and calibration sleeve, which is vacuum chamber, and connection vacuum chamber is provided with babinet
Water inlet and take out pressure mouth, the internal cavities of the calibration sleeve are sizing chamber, and the sizing chamber is diameter-changing cavity.
Preferably, one end of the diameter-changing cavity be circular ring shape, the other end be square.The both ends of the diameter-changing cavity
The fillet surface gradually changed by radius of curvature links up, and the radius of curvature of the fillet surface is from square end to circular ring shape end
Become larger.The fillet surface is preferably streamlined curved surface.
Preferably, the tank ends are provided with flange end cap and soft diaphragm seal, and the diaphragm seal
Internal diameter is less than the internal diameter of calibration sleeve.Straggly on the calibration sleeve to be evenly equipped with multiple vacuum ports, the shape of the vacuum port is preferred
For one or both of circular, strip.
Further, the water inlet is located at the lower end of the babinet, and the pumping pressure mouth is located at the upper end of the babinet.
The operation principle of the vacuum sizing box of above-mentioned square plastic expects pipe is：Plastic grain is inserted in the hopper of extruder, warp
Heating stirring, plastic grain become molten state, are successively extruded into through spiral propeller from head extrusion, obtain plastics
Guan Pei, Su Liao Guan Pei travel forward in sizing chamber；The cooling water enters vacuum chamber from the bottom to top from water inlet, takes out pressure mouth
Start to take out pressure, vacuum chamber is in vacuum state, due to being in vacuum state in vacuum chamber, the boiling point of cooling water is lower, cooling water
Gasify in the vacuum chamber, the gas after gasification leaves vacuum chamber by taking out pressure mouth, and cooling water decalescence in the vacuum chamber, takes away
Heat realizes that to the cooling sizing of Su Liao Guan Pei sizing chamber is the diameter-changing cavity become larger in curvature reducing, to Su Liao Guan Pei into
Row sizing, since fillet surface is flowing transition curved surface, so being the smooth side in surface in the plastic tube that square calibre comes out
Shape pipe.The vacuum sizing box of square plastic expects pipe described in the utility model, can be timely and effectively right between extruder and water tank
Tubing carries out sizing processing, and structure square shaped tubing cooling sizing is uniform, and obtained square pipe surface is smooth；In addition, by
In square plastic tubing, occupation rate is relatively low in the market, and the manufacturer of plastic pipe is without the extruder for needing to change modeling material pipe Pei
Head, need to only install the vacuum sizing pipe of square plastic expects pipe described in the utility model before extruder head, and other equipment is kept not
Change can be used to manufacture square plastic expects pipe, reduce the equipment investment cost of manufacturer.
The above-mentioned description to embodiment is understood that for ease of those skilled in the art and using this practicality
It is new.Person skilled in the art obviously easily can make these embodiments various modifications, and illustrating herein
General Principle be applied in other embodiment without by performing creative labour.Therefore, the utility model is not limited to here
Embodiment, those skilled in the art's announcement according to the present utility model, does not depart from the improvement that the utility model category is made
