Description
Technical field
The utility model relates to a kind of three-layer co-extruded blow moulding machine extruder head, especially relates to a kind of novel three-layer co-extruded blow moulding machine extruder head that is used for the multi-layer packaging goods.
Background technology
As everyone knows, three-layer co-extruded blow moulding machine extruder head is mainly used in antiseep, the etch-proof multi-layer packaging industries such as producing agricultural chemicals, cosmetics, beverage.Domestic production producer adopts import equipment to produce mostly at present, and the several families of domestic equipment adopt; But no matter be imported product or home products, equal thickness of uncontrollable its goods, in uneven thickness, the unstable product quality of its goods.
In addition, abroad feed stream is far away through the distance of runner in the design of other producers, has caused thus to plastify bad shortcoming, causes easily that raw material turns to be yellow in head, zoom, produces the phenomenon generation that stain etc. influence plastics performance; Bring unnecessary loss to manufacturer.
And in the market multilayer handpiece structure complexity, dismounting reach 2-3 days man-hour, and the cost of its installation and dismounting is huge, has caused unnecessary waste.
The utility model combine for many years manufacturing experience and to using client's investigation in many ways, development and production meet the three-layer co-extruded blow moulding machine extruder head of user's request fully.
Summary of the invention
The utility model mainly is loaded down with trivial details etc. the technical problem of, unstable product quality inhomogeneous at the existing in prior technology products thickness, runner distance, complex structure, dismounting, provide a kind of products thickness evenly, the three-layer co-extruded blow moulding machine extruder head of short, simple in structure, the easy accessibility of constant product quality, runner distance
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of three-layer co-extruded blow moulding machine extruder head, comprise main body, lower body and the core that is arranged on body interior, the main body side is connected with feeding cylinder, it is characterized in that the described main body outside is respectively arranged with several charging barrels, described charging barrel links to each other with core by runner respectively; The core outside is arranged with several spiral covers.The multilayer raw material enters runner by the charging barrel respectively, each raw material respectively by in the head separately runner enter spiral cover, each raw material is abundant plasticizing back and evenly bonding in the slit between each helical layer gland respectively, extrudes between core and mouthful mould then.
As preferably, described charging barrel is fixed on respectively by joint on the mounting flange in the main body outside, and the charging barrel comprises the secondary barrel in middle level, outer main barrel, the secondary barrel of nexine.The secondary barrel in middle level is mainly used in the injection binder materials, and outer main barrel is used to inject the PE material, and the secondary barrel of nexine is used to inject the EVOH material.
As preferably, described spiral cover stage casing is provided with the rotation screw thread.Make various raw materials inner bonding more even at spiral cover, it has avoided the common fault of the monolateral thickness of each layer effectively the design principle of other direct reducings of comparison, this spiral cover has adopted the principle of the gradual reducing of spiral, adopt four Cutter Body Processing with Machining Center, guarantee precision, thereby guaranteed the thickness uniformity of each layer raw material.
As preferably, described runner has comprised nexine runner, intermediate layer runner, outer runner; The intermediate layer runner is arranged between nexine runner and the outer runner.Runner is used to transmit raw material between each charging barrel and each helical layer gland; The utility model has shortened flow channel length, has reduced the time of staying of raw material in die head inside, under the situation that does not influence plasticizing, has avoided raw material to turn to be yellow in head, zoom, and the phenomenon that generation stain etc. influences plastics performance takes place.
As preferably, described spiral cover comprises nexine spiral cover, middle level spiral cover and outer spiral cover; The middle level spiral cover is arranged between nexine spiral cover and the outer spiral cover.Each raw material respectively in the slit between each helical layer gland full and uniform bonding back between core and mouthful mould, extrude.
As preferably, described end of body down is provided with the adjusting supporting plate; The bottom of regulating supporting plate is provided with regulating sleeve.Regulating supporting plate, to be used to regulate three layers of binder flake thickness thin, and regulating sleeve then is three layers and is stained with and closes material embryo one circle thickness and regulate uniformly.
Therefore, the utlity model has products thickness evenly, short, simple in structure, the easy accessibility of constant product quality, runner distance, characteristics such as easy and simple to handle.
