Abstract

The utility model relates to a plastic composite packing belt die head. The plastic composite packing belt die head comprises a core layer die body for squeezing out a core layer material, and a setting die for final setting, and further comprises a surface layer die body for extruding out a composite layer material, and a composite die for covering the core layer material in the composite layer material, wherein the surface layer die body, the core layer die body, the composite die and the setting die are sequentially connected and communicated with each other. With the structure, the plastic composite packing belt die head is capable of producing the packing belts in the composite structure through simple structure improvement, and therefore, the mechanical properties of the packing belts are greatly improved.

Description

The compound strap die head of plastics
Technical field
The utility model relates to the extrusion die for the production of plastic baling band, particularly a kind of die head of plastic baling band that can composite construction.
Background technology
Plastic baling band on the market all is the individual layer solid construction basically, and under the situation of same size, if strap is made lamination layer structure, its tensile strength increases by 30% than individual layer.And at present, producer is used all be can only output individual layer strap mechanical die head, this kind die head can't be accomplished composite construction, so demand those skilled in the art urgently the structure of existing individual layer strap die head is done certain improvement.
The utility model content
The utility model provides a kind of novel die head that can produce the composite construction strap in order to overcome the problems referred to above.
To achieve these goals, the utility model is achieved in that the compound strap die head of plastics, comprising: the sandwich layer die body is used for extruding core layer material; Typing mouthful mould is used for final molding; It is characterized in that: also comprise a top layer die body, be used for extruding compound coating layer; And one compound mouthful of mould, be used for core layer material is wrapped in the compound coating layer; This top layer die body, sandwich layer film body, compound mouthful of mould and mouthful mould of finalizing the design are linked in sequence and communicate.
Die body inside, described top layer is provided with upper and lower compound runner and this compound runner and the secondary feeding inlet that is arranged on the die body of top layer, and the end of this compound runner passes the import that described sandwich layer die body leads to described compound mouthful of mould; Described sandwich layer die body inside is provided with sprue and this sprue and the main feeding inlet that is arranged on the sandwich layer die body between upper and lower compound runner, the end of this sprue leads to the import of described compound mouthful of mould.
Position in sprue and upper and lower compound runner on the described sandwich layer die body is provided with regulating rod respectively versatilely, and an end of this regulating rod is positioned at corresponding runner, and the other end is arranged on outside the sandwich layer die body.
The end that described regulating rod is positioned at sandwich layer die body one end is hemispherical.
With said structure, the utlity model has following advantage: by simple architecture advances, make it possible to the strap of output composite construction, improve the mechanical property of strap greatly.
Description of drawings
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Fig. 2 is compound mouthful of mould of the present utility model.
Sequence number among the figure: 1,2 top layer die body; 3,4 sandwich layer die bodys; 5, the Flow-rate adjustment rod; 6, compound mouthful of mould; 7, typing mouthful mould; 8, round nut.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Shown in the figure is the compound strap die heads of plastics, comprising: the sandwich layer die body is used for extruding core layer material; Typing mouthful mould is used for final molding; One top layer die body is used for extruding compound coating layer; And one compound mouthful of mould, be used for core layer material is wrapped in the compound coating layer; This top layer die body, sandwich layer film body, compound mouthful of mould and mouthful mould of finalizing the design are linked in sequence and communicate.
Specifically, this die body inside, top layer is provided with upper and lower compound runner and this compound runner and the secondary feeding inlet that is arranged on the die body side, top layer, and the end of this compound runner passes the import that described sandwich layer die body leads to described compound mouthful of mould; Described sandwich layer die body inside is provided with sprue and this sprue and the main feeding inlet that is arranged on sandwich layer die body leading flank of a plurality of trouble shapes between upper and lower compound runner, the end of this sprue leads to the import of described compound mouthful of mould, and each outlet of sprue corresponding upper and lower compound runner, be that the melt that the melt of compound runner passes sandwich layer die body and sprue is pooled to compound mouthful of mould, formed the strap of composite construction.
Position in sprue and upper and lower compound runner on the described sandwich layer die body is provided with regulating rod and also tight with round nut by the mode of fine thread respectively.One end of this regulating rod is positioned at corresponding runner, and the other end is arranged on outside the sandwich layer die body.Each runner can namely, rotate and stretch out in the end of the Flow-rate adjustment rod of die body outer end by the online random independent regulation runner of Flow-rate adjustment rod gap, just can change opened gap on the runner to control the melt flow of this runner.And the end that described regulating rod is positioned at sandwich layer die body one end is hemispherical, guarantees that materials flow is smooth and easy, no dead angle.
When changing the different size goods, as long as unload the new typing mouth mould of fit on behind the typing mouthful mould trip bolt.So a typing mouthful mould can have plurality of specifications, change typing mouthful mould according to demand of practical production, typing mouthful mould is fastened on the compound mouthful of mould with one group of screw.
Below only expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
