Abstract

The utility model relates to the field of plastic box production, and particularly discloses a plastic box hinge which is firm in structure and convenient to recycle. The plastic box hinge comprises a base cloth layer, at least two panels and at least two inner plates, the panels are arranged on the outer surface of the base cloth layer, a gap is reserved between every two adjacent panels, and the inner plates are arranged on the inner surface of the base cloth layer. The plastic box hinge is high in firmness and tension resistance, low in production cost and convenient to use and is formed by injection molding, the length of the hinge can be determined as needed in production, additionally, materials of the plastic box hinge and materials of a plastic box belong to the same category, the plastic box hinge and the plastic box can be recycled together simply and conveniently, and unnecessary waste is reduced.

Description

Plastic box hinge

Technical field

The utility model relates to plastic box technical field, and especially a kind of attaching parts on the folding-type boxes such as plastic box, PP bending block case, plastic box is hinge.

Background technology

The attaching parts of existing hoarding box is all the metalworks such as aluminium, iron, its hoarding box is shabby scrap after, when hoarding box is recycled, iron hinge don't fail to be pulled down, sorting, classification after just recyclable.And the main body of hoarding box generally adopts plastics, rubber and plastic, PP cellular material etc., hoarding box consists of six or four square plates, by hinge, be connected and fixed between any two, and on each plastic box, there are a plurality of hinges, when reclaiming, because material is different, thereby cause dismounting extremely inconvenient, waste time and energy; In addition, the productive costs of iron hinge is relatively high, and the recovery of iron hinge is inconvenient, causes larger waste.

Utility model content

The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, and a kind of sound construction is provided, and reclaims plastic box hinge easily.

In order to achieve the above object, the plastic box hinge that the utility model is designed, it comprises base cloth layer, at least two panels, at least two inner panels; Panel is arranged between the outside face of base cloth layer and adjacent two panels interval, inner panel is arranged on the inside face of base cloth layer, inner panel is corresponding one by one with panel, corresponding inner panel is corresponding with panel size, profile is identical, inner panel and panel are symmetricly set on the tow sides of base cloth layer, and inner panel is consistent with the length direction that panel is arranged on base cloth layer; Base cloth layer is longitudinal arrangement by being multiply PP wire harness, laterally for PP flexible cord is wrapped in longitudinally on wire harness, weaves and forms.

Described panel can be square plate, and inner panel can be the hole that rule is arranged for square plate and square plate are provided with, and this hole is circular, square, rhombus etc.; Described panel can be square plate, and inner panel is square plate, on corresponding panel and inner panel, all can be provided with knock hole.

Described panel can be three, the inner panel corresponding with panel also has three, in order to make hinge holding capacity larger, middle inner panel is provided with reinforced rib, described reinforced rib is for along laterally having extended upward a plurality of projections on the length direction of inner panel, and a plurality of projections link into an integrated entity by dowel longitudinally.

The production method of plastic box hinge: have a side of hinge mold base to enter base cloth layer, when base cloth layer covers after whole hinge mold base, hinge mould upper body presses down, coordinate with hinge mold base, injecting PP plastics to hinge mould inside, after PP plastics are cooling, raise hinge mould upper body, base cloth layer moves forward, and repeats above-mentioned injection moulding process after blank base cloth layer is covered with hinge mold base.

In the inside of hinge mould upper body and the through hole correspondence position on adapter plate, be provided with push rod, in injection moulding process, push rod withstands base cloth layer, makes base cloth layer be positioned at the midway location of adapter plate.

The production method of another kind of plastic box hinge: first base cloth layer is carried out to pre-setting by thermocompression forming device, base cloth layer after pre-setting is sent in double-coating mould, base cloth layer enters after double-coating mould, by extruder, the both sides of base cloth layer will be compounded in after PP plastic extruding forming, then by coating mould, export sizing output, hinge after output is by traction machine continuous traction, and it is compound that extruder continues extrusion molding, after finally cutting by Len req with cutting machine, is finished product.This extrusion molding is produced plastic box hinge, and its production capacity is large, and production efficiency is high, is applicable to producing in enormous quantities.

The resulting plastic box hinge of the utility model, its base cloth layer adopting is formed by PP plastic knitting, and also or extrusion moulding plastic injection-moulded by PP of adapter plate, its sound construction, fastness is large, and resistance to tension is strong, productive costs is lower, and simultaneously it is by injection molded, and produces and can make the length of hinge determine with the need, easy to use, in addition, its material and plastic box material belong to same class, when reclaiming, can reclaim together with plastic box, simple and convenient, reduced unnecessary waste.
