Abstract
The utility model provides a diameter, its characterized in that: that crowd steady bubble frame of blown film device altogether, surrounding membrane bubble set up and are used for the stable film bubble including the compressed air chamber of circumference evenly distributed at membrane bubble outer peripheral face, the panel that encloses into compressed air chamber sets up with membrane bubble outer peripheral face interval relatively, and this panel evenly distributed has a plurality of ventholes, and compressed air chamber and compressed air source are connected, the utility model has the advantages of simple structure, surely steep effectual.
Description
Technical field
What this utility model related to a kind of coextrusion film blowing device surely steeps frame.
Background technology
It is by multiple stage extruder, several similar and different resins are carried out plasticizing to extrude that co-extrusion blows my slight skill art, enter die head and carry out composite co-extruding, obtain the thin film with certain function, including changing barrier packaging film, shrink film, vacuum freshness retaining film, geomembrane etc., can be widely used for food, medicine, daily chemical products is packed, the fields such as agricultural roc film, multi-layer co-extruded thin film has and well blocks water, resistance oxygen, resistance carbon dioxide, oil resistance performance, the market demand is increasing, owing to domestic food is packed, the market demand of the plural layers such as plastic film for agricultural use increases, also promote the development of multi-layer co-extruded equipment.
The die head of coextrusion film blowing equipment is provided with annular die; extrude from annular die after multi-layer resinous compound; inflation forms film bubble; and it is pulled rising with identical speed; in order to ensure that film bubble has stable diameter, it will usually setting surely steeps frame around film bubble outer peripheral face, but existing steady bubble shelf structure is complicated; foam stabilizing effect is poor, it is impossible to meet production requirement.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, it is provided that the coextrusion film blowing device that a kind of simple in construction, foam stabilizing effect are good surely steep frame.
The purpose of this utility model realizes by following technical solution:
A kind of coextrusion film blowing device surely steep frame, the diameter of stable bubble it is arranged to around film bubble, it is characterized in that: include even circumferential and be distributed in the delivery air chamber of film bubble outer peripheral face, the panel and the film bubble outer peripheral face interval that surround delivery air chamber are oppositely arranged, this panel is evenly distributed with multiple venthole, and delivery air chamber is connected with compressed air source.
Further, the aperture of the venthole of described panel is 0.2-0.5 millimeter.
Further, described panel every square centimeter has 5-10 described venthole.
This utility model has the advantages that
Steady bubble frame is for the diameter of stable bubble, have the panel of venthole can stablize gently output action at the air-flow of film bubble outer peripheral face, so that film bubble has stable diameter, the setting of the aperture of venthole and arrangement density can make air-flow more stable and mild, acts on film bubble outer peripheral face and does not have the problem that unbalance stress causes deformation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to shown in Fig. 1, a kind of coextrusion film blowing device, including die head 1, vane 14 and steady bubble frame 3.
Die head 1 has core rod 12 and the die sleeve 11 around core rod 12, and between core rod 12 and die sleeve 11, coaxial spaced is arranged to form annular die 13, and core rod 12 end face is provided with inflation pore 121, and resin is extruded from annular die 13 and formed film bubble 2 after inflation.Vane 14 is arranged on outside annular die 13.
Steady bubble frame 3 includes support 31, be arranged on support 31 and even circumferential is distributed in the delivery air chamber 33 of film bubble outer peripheral face, the panel 331 and the film bubble 2 outer peripheral face interval that surround delivery air chamber 33 are oppositely arranged, this panel 331 is evenly distributed with multiple venthole, delivery air chamber 33 is connected with compressed air source, the aperture of the venthole of panel 331 is 0.2-0.5 millimeter, panel 331 every square centimeter there is 5-10 described venthole.
The above, it is only preferred embodiment of the present utility model, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence namely made according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model patent contains.
