Description

Large-scale cavity blowing bucket of double-deck PE

Technical Field

The utility model relates to a plastic products production technical field specifically is a large-scale hollow blowing bucket of double-deck PE.

Background

The plastic barrel is mainly used for storing and transporting various liquids, has good characteristics for special dangerous goods packaging, has the characteristics of being not easy to break, not rusting, light in weight and the like, has good oil resistance and strong corrosion resistance, is mainly used for packaging dangerous goods needing heat preservation, moisture protection, pressure resistance and corrosion resistance, and is mainly made of polyethylene, polypropylene, polyester and other plastics.

However, the existing large plastic bucket has the following disadvantages: the plastic barrel is injection molding in the market at present, the product is of a single-layer structure, color master is added during product processing to obtain the good appearance of the product, the use environment-friendly property is poor, the injection molding process determines the molecular orientation defect of plastic molecules in the molding process, the impact strength and the tensile strength of the product are not ideal, the product is easy to damage, and improvement is needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a large-scale cavity of double-deck PE blows moulding barrel to this type of plastic drum is injection moulding processing shaping in solving the existing market that mentions in the above-mentioned background art, and the goods is individual layer structure, and all adds look mother during product processing, in order to gain the good outward appearance of goods, uses the feature of environmental protection not good, and injection moulding technology decides the plastics molecule at shaping process molecule orientation defect, and the impact strength and the tensile strength of product are all unsatisfactory, the problem of the easy damage of product.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a large-scale hollow blowing bucket of double-deck PE, includes the blowing staving, the blowing staving includes external coloring layer and the this chromatograph of interior raw materials, and interior raw materials true color level is inside external coloring layer, external coloring layer and the this chromatograph of interior raw materials form double-deck parison in the storage die head, and external coloring layer and the this chromatograph of interior raw materials connect through extrusion hot melt mode in extrusion die head and form integratively, external coloring layer and interior raw materials true color layer form the monolithic, the blowing staving adopts cavity blow molding technology preparation to form.

Preferably, the outer dyed layer lateral wall is smooth setting, this chromatograph inner wall of interior raw materials is smooth, the outer dyed layer does not have the layering with this chromatograph of interior raw materials and mixes the layer, and the ectonexine layering is clear.

Preferably, the top ends of the outer coloring layer and the inner raw material color layer are provided with extension ends, and the extension ends of the outer coloring layer and the inner raw material color layer are thermally fused through extrusion extension ends of a blow molding die of a die head inner flow channel.

The utility model provides a large-scale hollow blowing bucket of double-deck PE possesses following beneficial effect:

(1) the utility model discloses an adopt bilayer structure with the product, the skin is painted, and inlayer raw materials true qualities because the inlayer does not have the colorant when having solved product appearance, can not produce the migration during the use, can not influence the interior content quality, uses more relieved environmental protection.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a schematic structural view of a cross-sectional view of the present invention.

In the figure: 1. blowing the barrel body; 2. an outer coloring layer; 3. the inner raw material is the original color layer.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-2, the utility model provides a technical solution: the utility model provides a large-scale hollow blowing bucket of double-deck PE, includes blowing staving 1, blowing staving 1 includes external coloring layer 2 and the local chromatograph 3 of interior raw materials, and interior raw materials this chromatograph 3 is located external coloring layer 2 inside, external coloring layer 2 forms double-deck type embryo with the local chromatograph 3 of interior raw materials in storage die head, and external coloring layer 2 and the local chromatograph 3 of interior raw materials connect through extrusion hot melt mode in extrusion die head and form integratively, external coloring layer 2 and the local chromatograph 3 of interior raw materials form the monolithic layer, blowing staving 1 adopts cavity blow molding technology preparation to form.

The side wall of the outer coloring layer 2 is smoothly arranged, the inner wall of the inner raw material original color layer 3 is smooth, the outer coloring layer 2 and the inner raw material original color layer 3 have no layering and mixing layer, the layering of the inner layer and the outer layer is clear, and the blow molding effect of the double-layer barrel is good; the outer dyed layer 2 all is equipped with the extension end with this chromatograph 3 tops of interior raw materials, and the extension end of outer dyed layer 2 and this chromatograph 3 of interior raw materials is through the extrusion of die head internal flow channel blowing mould and is extended end hot melt, can guarantee that the leakproofness that outer dyed layer and this chromatograph hot melt of interior raw materials are connected is good.

The utility model discloses an adopt bilayer structure with the product, the skin is coloured, inlayer raw materials true qualities, when having solved product appearance because the inlayer does not have the colorant, can not produce the migration during use, can not influence content quality, use more relieved environmental protection, through adopting the cavity blowing mode, the plastics molecule is two-way stretched when the shaping, the orientation is abundant, make product property can improve greatly on injection moulding's basis, the durability of product has been improved, user's use cost has been reduced.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
