Being placed on same straight line, the second cone double screw extruder is vertical on three-layer co-extruded die body 100.This utility model first is bored double
Screw extruder and three-layer co-extruded die body 100 are placed on same straight line, therefore referred to as cross-flow type.Second cone double screw extruder is vertical
It is located on three-layer co-extruded die body 100, thus the most rectilinear.
Being provided with First Transition set 201 between the first cone double screw extruder and three-layer co-extruded die body 100, the first material divides
Flow cone 101 is located in First Transition set 201.It is connected with the first linkage section 102, second on three-layer co-extruded die body 100 in turn to connect
Section 104, the second material diversion cone 103 is located between the first linkage section 102 and the second linkage section 104；Second cone twin-screw extrusion
Machine is connected with three-layer co-extruded die body 100 by one second spacer shell 202, the second spacer shell 202 and the company of three-layer co-extruded die body 100
The place of connecing is provided with a runner skewback 300.First material diversion cone 101, first linkage section the 102, second material diversion cone 103, second
Linkage section 104 is sequentially connected with in a straight line.
The operation principle of three-layer co-extruded plastic pipe process units is: same or different types of plastics are separately added into
Two extruders carries out material plasticizing, the material extrusion after plasticizing is transported in the runner each distributed, then same
Runner collects melted being complex as a whole, flows out and extrusion molding in molding mouth die from the second linkage section 104.
This utility model first is bored double screw extruder and is placed on same straight line with three-layer co-extruded die body 100, and cross-flow type sets
Putting, reasonable in design, production process is simple, low cost of manufacture, the stream direction of material extrusion and the first cone double screw extruder side
To unanimously, flow velocity is happy, and Flow of Goods and Materials is uniform and stable, and what the present embodiment first bored double screw extruder extrusion is intermediate layer thing
Material.Other second cone double screw extruder is vertical on three-layer co-extruded die body 100, and perpendicular formula is arranged, at the first linkage section
Forming circulation state on 102 makes material discharging uniform and stable, and finished product Sizing precision is high, and presentation quality is good, and yield is high, this enforcement
What example second bored double screw extruder extrusion is inside and outside layer material.This utility model by cross-flow type and rectilinear perfect adaptation, and
Being provided with a runner skewback 300 in the junction of the second spacer shell 202 with three-layer co-extruded die body 100, runner skewback 300 tilts in one
Streamlined setting so that rectilinear material can tilt, smoothly flow therein in three-layer co-extruded die body 100, does not stay dead angle, this reality
With novel by cross-flow type with the rectilinear optimization carried out on structural grouping so that material plasticizing is uniformly abundant, Flow of Goods and Materials is smooth and easy,
Uniformly, stablizing, the tubing profile of molding is the most attractive in appearance smooth, and tube wall thickness is uniform, and three lamination moulds are effective, simple in construction, if
Meter rationally, modern design and practical.
It is arranged with the 3rd spacer shell 203 outside second material diversion cone 103, outside the second linkage section 104, is arranged with the 4th transition
Set 204, is arranged with outside the first material diversion cone 101 outside First Transition set the 201, second material diversion cone 103 and is arranged with the 3rd mistake
Cross and outside set the 203, second linkage section 104, be arranged with the 4th spacer shell the 204, second cone double screw extruder and three-layer co-extruded die body
The second spacer shell 202, First Transition set the 201, second spacer shell the 202, the 3rd spacer shell the 203, the 4th spacer shell it is provided with between 100
204 equal surfaces are straight, and inwall polishes and plates Lip river and processes, and smooth smooth-going, it is simple to material plasticizing the most even raising stream stability makes
Obtaining three lamination moulds effective, without die parting line, finished product is aesthetic in appearance smooth and easy and has gloss, simple in construction, and reasonable in design, moulding is only
Special.
In the present embodiment, three-layer co-extruded die body the 100, the 3rd spacer shell the 203, the 4th spacer shell 204 all passes through Flange joint
Mode is attached fixing.Molding mouth die is connected by flange connection and the 4th spacer shell 204.In sum, this practicality
Each parts of novel three-layer co-extruded plastic pipe process units all are attached fixing by flange connection, and combination is installed
Convenient and swift, later stage repair and maintenance is simple, and can easily, simple, the water of the three-layer co-extruded plastic pipe process units of quick adjustment
Square improve the quality of finished product to improve the stability of Flow of Goods and Materials.
Extrusion device in currently available technology is set to separate unit extruder more, and separate unit extruder working performance is low, and only
Being suitable for producing monolayer plastic tubing, the device scope of application is narrow, and product variety is single, and production cost is high, and specification is big, wall ratio
Thicker product, material plasticizing is abundant not, and the outward appearance of product does not all reach with performance and compares high level, and finished product is coarse, essence
Spend low.And if produce laminated plastics tubing, which floor typically has just have several extruders supporting to complete, such as, produces three layers altogether
Squeezing plastic pipe, traditional then needs three extruders, the most not only power consumptions, and adds the investment cost of device, the most not
Economy, floor space is bigger simultaneously.For solving prior art problem, the three-layer co-extruded plastic pipe that the utility model proposes is raw
Produce device, solve use separate unit extruder work brought inefficiency, be only suitable for produce monolayer plastic tubing, be suitable for
The problems such as narrow scope, product variety are single, production cost is high, finished product is coarse, precision is low.Meanwhile, three-layer co-extruded moulding is completed
The production of material tubing, only need to support the use the first cone double screw extruder, the second cone double screw extruder, and two extruders just may be used
Complete, more traditional structure, save an extruder, not only reduce investment cost, and decrease shared by device
Space, extruded velocity is fast, and working performance is high, applied widely, low cost of manufacture, and the product specification of production is complete, and production capacity is high, and
Good product quality, precision is high.Therefore, this utility model achieve a kind of simple in construction, low cost of manufacture, material plasticizing fully,
The three-layer co-extruded plastic pipe process units that production efficiency is high, production capacity is high, end properties is good.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Every equivalent structure transformation utilizing this utility model description and accompanying drawing content to be made, or directly or indirectly it is used in other phases
The technical field closed, is the most in like manner included in scope of patent protection of the present utility model.
