Abstract
The utility model relates to a plastic film molding device, particularly to a composite coextrusion film blowing machine head which can be used for making two kinds of plastic films with different degradation functions. The machine head is a core rod type coextrusion film blowing machine head which adopts coextrusion of double machines, double flow paths, and a single layer composite process of inner flow separation. The plastic film molding device can directly produce the plastic film, wherein, the middle part of the plastic film is a photodegradation transparent film for culturing seedlings, and both sides are burial biodegradation films; the utility model replaces the traditional single degradation film which has the defects that the traditional single degradation film can be degraded as the traditional single degradation film is exposed, and the traditional single degradation film can not be degraded as the traditional single degradation film is buried in earth; two flow paths are arranged inside the film blowing machine head, and two different raw material can respectively enter one of the machine heads and can not be mixed. The utility model has the advantages of simple structure, convenient operation, and reduced production cost.
Description
The utility model relates to a kind of parts of plastic sheeting former, belongs to plastic processing technology equipment, and it is a kind of composite co-extruding blown-film die of making two kinds of different degradation function plastic sheetings.
Existing plastic film blowing machine is by the plastic foil extruder, compositions such as feed distributor, mould, subsidiary engine.Original production method is to be extruded the plastic sheeting of single or multiple lift same nature by separate unit or many extruders, because existing plastic foil production equipment, the most of mulch film in rural area can not use two degraded raw materials, so can not in time be degraded and be formed new white pollution.
The purpose of this utility model is to provide a kind of head of making the degradative membrane goods of the two two kinds of different materials of component of individual layer, and this head is to adopt two-shipper co-extrusion, dual channel, the compound core rod type coextrusion film blowing head of interior shunting individual layer.
The purpose of this utility model is achieved in that it mainly comprises parts such as handpiece body, plug, mouthful mould, below described handpiece body and the side have the first flow and second runner, they pass separately handpiece body via plug to die orifice; Be provided with branching block in the described plug; In handpiece body bottom and core rod joint positioning key is installed; Described first flow is by the annular feeding inlet in flange clip and the transition body; Described second runner is linked to each other with extruder by the flange clip by connector; Described plug top is equipped with clamp nut.
The utility model compared with prior art, the goods of producing become 1/2nd annular base shapes, behind the moulding automatic cutting, be the transparent seedling film of light degradation in the middle of becoming, both sides are for burying Biodegradable films, replaced that traditional single degradative membrane exposes degraded, soil buries the shortcoming of not degrading, and be provided with two runners in the blown-film die, two kinds of different raw materials are entered in the head simultaneously; Simple in structure, easy to use, reduced production cost.
Below in conjunction with accompanying drawing the utility model is described further;
Fig. 1 is a structural representation of the present utility model.
(1) plug among the figure; (2) clamp nut; (3) core rod; (4) mouthful mould; (5) handpiece body; (6) positioning key; (7) first flow; (8) second runners; (9) connector; (10) flange clip; (11) transition body; (12) die orifice.
Started shooting simultaneously by two extruders among the figure, extrude different material, wherein, the biodegradation raw material evenly enters first flow (7) by the annular charging aperture in the transition body (11), locates to die orifice (12) via plug (1); The light degradation raw material is also located to die orifice (12) via second channel (8), plug (1) by connector (9), owing to be provided with branching block in the plug (1), so two kinds of raw materials do not mix in head mutually, have only to die orifice (12) locate two kinds of raw materials just join bonding, thereby extrude desirable degradable film goods; The available spacing with transfer core rod (3) and handpiece body (5) of clamp nut (2) on the plug (1), thereby the size of controlled molding mouth (12) are extruded the film of different-thickness.
Claims (3)
1, a kind of biodegradable plastic composite co-extruding blown-film die, it mainly comprises handpiece body (5), plug (3), mouthful mould parts such as (4), it is characterized in that: described handpiece body (5) below and side, have first flow (7) and second runner (8), they pass handpiece body (5) separately, via plug (1) to die orifice (12); Described plug is provided with branching block in (1); In handpiece body (5) bottom and core rod (3) joint positioning key (6) is installed.
2, a kind of biodegradable plastic composite co-extruding blown-film die according to claim 1 is characterized in that: described first flow (7) is by the annular feeding inlet in flange clip and the transition body (11); Described second runner (8) is linked to each other with extruder by flange clip (10) by connector (9).
3, a kind of biodegradable plastic composite co-extruding blown-film die according to claim 1, it is characterized in that: described plug (1) top is equipped with clamp nut (2).
