The compound extruded system of pipe production line
Technical field
It the utility model is related to tube extruding equipment field.
Background technology
Common composite plastic pipe either ABA structures or ABC structures(Wherein, A, B, C represent tubing section material),
Mode as generally use is realized during the manufacturing:One production line is by two or three extruders as altogether
Enjoy main frame while extrude, but such mode production efficiency is low.Production efficiency is improved in a short time, it usually needs purchase
Buy two or a plurality of same production line carrys out guaranteed efficiency, at the same time, share the quantity of main frame also in increase at double, it is raw
Produce cost increase;Secondly, the wall ratio of tubing is usually required that during compound extruded larger difference(Such as 1:8:1);
In actual production process, a production line can only produce the tubing of ABA or ABC different structures, it is impossible to which both take into account progress.

Feed pipe, described feed pipe include main feed pipe, connect the stratified feeding pipe of described main feed pipe, described stratified feeding
Pipe is connected at first point of described charging aperture;
Multiple shared main frames, it is separately positioned between two neighboring described plastic extruder, described shared main frame bag
Include the second head, flow distribution device, main flow pipe that described flow distribution device includes being connected on the second described head,
Two isocons being connected with described main flow pipe, the isocon described in two are connected to two second point of charging apertures
Locate, the flow regulator for controlling flow is provided with described isocon.
In above-mentioned technical proposal, it is preferred that described flow regulator is choke valve.
In above-mentioned technical proposal, it is preferred that it also includes a controlling organization, described controlling organization respectively with it is each described
Plastic extruder, shared main frame connects with signal.
In above-mentioned technical proposal, it is preferred that along the axial line bearing of trend of described isocon, described isocon
There is terminal part internal diameter first to taper into the hourglass portion become larger again.
In above-mentioned technical proposal, it is preferred that be connected with bending between second point of described charging aperture and described hourglass portion
Joint.
In above-mentioned technical proposal, it is preferred that be respectively arranged with valve on described main feed pipe, stratified feeding pipe.
The utility model obtains following beneficial effect compared with prior art:In this case, each two plastic extruder is shared
One shared main frame so that the system can be realized while extrude the tubing of different structure, improve production efficiency, reduce cost.

Embodiment
To describe technology contents, construction feature, institute's reached purpose and effect of utility model in detail, below in conjunction with implementation
Example simultaneously coordinates accompanying drawing to be described in detail.
The structure of composite pipe has many kinds, such as ABA, ABC, AA, AB, AC, BC(Wherein A, B, C represent tubing section
Material)Deng.
As shown in Figure 1, the system includes multiple plastic extruders 1, multiple shared main frames 2, these Hes of plastic extruder 1
Shared main frame 2 is adopted to be set in such a way:Separate unit is shared main frame 2 and is arranged between two adjacent plastic extruders 1 so that
Every two plastic extruders 1 can share a shared main frame 2.
Plastic extruder 1 includes the first head 11, mould 12.Mould 12 includes 121, first points of main feed mouth
122, second points of charging apertures 123 of charging aperture.A feed pipe 13 is connected between the head 11 of main feed mouth 121 and first, is fed
Pipe 13 includes main feed pipe 131, the stratified feeding pipe 132 of connection main feed pipe 131, and stratified feeding pipe 132 is connected to first point
At charging aperture 122.Therefore, separate unit plastic extruder can realize a kind of layering extrusion of section material of tubing, for example, can be with
Extrude the MULTILAYER COMPOSITE tubing such as AA, BB, CC.
Shared main frame 2 includes the second head 21, flow distribution device 22.Flow distribution device 22 includes being connected to the second machine
Main flow pipe 221 on first 21, two isocons 222 being connected with main flow pipe 221.In order to realize that same shared main frame 2 is same
When be adjacent two plastic extruders 1 supplying material, two isocons 222 are connected to two second point of charging apertures 123
Place.During the compound extruded of tubing, in order to by the wall thickness control of tubing in the scope needed for technique(Such as 1:8:1),
Flow regulator 223 is respectively arranged with two isocons 222.Preferably, flow regulator 223 can be throttling
Valve.In order to allow the material to even into mould 12, it is first gradual that the terminal part of each isocon 222 is respectively provided with internal diameter
Diminish and become larger hourglass portion 2221 again.For the ease of isocon 222 is arranged at second point of charging aperture 123, at second point
Crooked joint 224 is connected between charging aperture 122 and hourglass portion 2221.Different cross section material is selectively extruded in order to realize
Tubing, the valve 133 that control pipeline opens or closes is separately provided on main feed pipe 131, stratified feeding pipe 132.
The system also includes a controlling organization 3, and controlling organization 3 connects with signal with each plastic extruder 1, shared main frame 2 respectively.
Adjacent two plastic extruders 1 can extrude the tubing that section material is A, B respectively, be arranged at this two plastic extrusions
It is C that shared main frame between machine 1, which can be supplied to section material,.When closing flow regulator 223, two plastic extruders 1 are single
Only operation, then mould 12 can extrude respectively section material be AA, BB tubing, when flow regulator 223 is opened,
Two plastic extruders 1 and the operation simultaneously of shared main frame 2, then it is ACA, BCB that mould, which can extrude section material respectively,
Tubing.By that analogy, the compound extruded system of the pipe production line can extrude the tubing of multiple section material simultaneously.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
