Abstract
The invention relates to a polyethylene winding structure wall tooth-shaped pipe. The polyethylene winding structure wall tooth-shaped pipe comprises an inner wall layer and a covering layer, wherein the covering layer is an outwardly projected reinforcing rib formed in such a way that a tubular polyethylene strip covers a framework pipe and is wound on the outer surface of the inner wall layer; the outwardly projected reinforcing rib is spirally pressed at the lap-joint seam of the edges of the adjacent sheet-shaped polyethylene strips; the tubular polyethylene strip is a tooth-shaped tubular polyethylene strip with sawteeth formed on the outer wall; and uniformly distributed longitudinal grooves are formed in the outer wall of the tooth-shaped tubular polyethylene strip through the sawteeth. The invention further relates to a tooth-shaped strip forming die of the polyethylene winding structure wall tooth-shaped pipe. The polyethylene strip outlet of the tooth-shaped strip forming die is a tooth-shaped tubular strip outlet. According to the polyethylene winding structure wall tooth-shaped pipe, the covering layer is quick in radiating and shaping, the framework pipe is difficult to deform, the profile height is guaranteed, the product ring is large in height, and the designed ring stiffness can be completely achieved; and the tooth-shaped strip forming die can be used for extruding the tooth-shaped tubular strip. Therefore, the polyethylene winding structure wall tooth-shaped pipe and the tooth-shaped strip forming die can be widely applied to the field of plastic pipe processing.
Description
Technical field
The invention belongs to the plastic tube manufacture field, particularly a kind of polyethylene spirally enwound structure-wall profile of tooth tubing and profile of tooth strip molding port mould.
Background technique
Polyethylene spirally enwound structure-wall tubular product is that hot technology entwining tube is main raw material(s) with the high-density polyethylene resin; Adopt hot winding shaping process; With polypropylene skeleton pipe is auxiliary support structure, a kind of special construction wall pipe with higher critical external compressive resistance ability of processing.Its mode of production: raw material is delivered to heating in the extruder, plasticizing, homogenizing after runner, mouthful mould are extruded into flat strip respectively and in order to coat the arc strip of skeleton pipe, equidistantly are wrapped on the die surface through the vacuum feeder.At present, the arc strip die geometry form that coats the skeleton pipe has two kinds: the one, and U type structure partly coats the skeleton pipe, and the 2nd, O type structure encases the skeleton pipe fully.The product that the mouth mould of these two kinds of structural types is produced; It coats the arc strip smooth outer surface of skeleton pipe; Form the plane, the heat of strip is difficult for distributing, and when the skeleton pipe equidistantly is wrapped on the die surface, is prone to make the deliquescing of being heated of skeleton pipe; Type is high to be reduced, and makes product not reach the design ring stiffness.For satisfying the requirement of product ring stiffness, just need to increase the thickness of the arc strip that coats the skeleton pipe, increased cost of production.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, provide a kind of skeleton pipe not yielding, the assurance type is high, and product reaches the polyethylene spirally enwound structure-wall profile of tooth tubing and the profile of tooth strip molding port mould of the requirement of design ring stiffness.
It is to adopt following technological scheme to realize that the present invention solves its technical problem:
A kind of polyethylene spirally enwound structure-wall profile of tooth tubing; Constitute by inner wall layer and clad; Inner wall layer is served as reasons, and sheet shaped polyethylene strip spiral twines and each adjacent strip edge overlaps the continuous solid wall pipe that merges formation successively each other; Clad is wound in the evagination stiffening rib that the inner wall layer outer surface forms after coating the skeleton pipe by the tubular polyethylene strip; The overlap joint of this evagination stiffening rib spiral cross-pressure in each adjacent sheet shaped polyethylene strip edge melts commissure, it is characterized in that: said tubular polyethylene strip is the profile of tooth tubular polyethylene strip that outer wall is shaped on sawtooth, and this profile of tooth tubular polyethylene strip outer wall forms equally distributed longitudinal groove through sawtooth.
And the sectional shape of described profile of tooth tubular polyethylene strip is: " O " shape, " U " shape, anti-" 9 " font of opening figure six, the anti-figure six of opening, opening " 9 " font or opening.
And the single tooth sectional shape of the made sawtooth of described profile of tooth tubular polyethylene strip outer wall is trapezoidal, triangle, rectangle or circular.
A kind of profile of tooth strip molding port mould of polyethylene spirally enwound structure-wall profile of tooth tubing; Constitute by mouth mould main body; Outlet end in this mouthful mould main body is shaped on coaxial skeleton pipe outlet and the outlet of polyethylene strip, and polyethylene strip outlet ring is characterized in that around the periphery of skeleton pipe outlet: said polyethylene strip outlet is the outlet of profile of tooth tubulose strip; The inner wall smooth of this profile of tooth tubulose strip outlet, the outer wall of profile of tooth tubulose strip outlet is shaped on the sawtooth that is uniformly distributed with.
And described profile of tooth tubulose strip outlet is " O " shape, " U " shape, anti-" 9 " font of opening figure six, the anti-figure six of opening, opening " 9 " font or opening.
And the single tooth sectional shape that said profile of tooth tubulose strip outlet outer wall is shaped on the sawtooth that is uniformly distributed with is triangle, trapezoidal, rectangle or circular.
Advantage of the present invention and beneficial effect are:
1. polyethylene spirally enwound structure-wall profile of tooth tubing of the present invention; The outer surface that coats the tubular polyethylene strip (being clad) of skeleton pipe no longer is a smooth flat, but zigzag fashion promptly forms longitudinal groove; It has increased the heat diffusion area of cover surface; Make the clad rapid heat dissipation, typing is fast, the skeleton pipe is not yielding, the type that guaranteed is high, product ring height is high, can reach the design ring stiffness fully.
2. polyethylene spirally enwound structure-wall profile of tooth tubing of the present invention, the sectional shape of profile of tooth tubular polyethylene strip is: " U " shape, " O " shape; Anti-" 9 " font of opening figure six, the anti-figure six of opening, opening " 9 " font or opening except traditional totally enclosed type " O " shape, can also form semi-enclosed " U " shape; And anti-" 9 " font of the anti-figure six of opening figure six, opening of partial, opening " 9 " font or opening; Like this, the skeleton pipe is not encased fully, can be because of the deliquescing of being heated; Simultaneously, coat strip and be difficult for forming bulge.When the skeleton pipe equidistantly is wrapped on the die surface; The afterbody strip of anti-" 9 " the font tubular polyethylene strip of opening figure six, the anti-figure six of opening, opening " 9 " font or opening coats the skeleton pipe more fully; Guaranteed that product type is high; Improve ring stiffness, improved appearance quality.
3. profile of tooth strip molding port mould of the present invention; Its polyethylene strip outlet outer tube wall changes serrated face into by the light face, and making the outer surface generation longitudinal groove of strip is profile of tooth, thereby increases the heat diffusion area of strip; Heat is prone to distribute; Guaranteed that product type is high, improved ring stiffness, improved appearance quality.
4. polyethylene spirally enwound structure-wall profile of tooth tubing of the present invention, clad rapid heat dissipation, typing are soon, the skeleton pipe is not yielding, the type that guaranteed is high, and product ring height is high, can reach the design ring stiffness fully; Molding port mould of the present invention can be used for extruding profile of tooth tubulose strip, and the present invention can be widely used in the plastic tube machining technology.
