Description
Technical field
The present invention relates to a kind of plastic bottle, particularly a kind of plastic bottle and preparation technology thereof.
Background technology
L ring Plastic Drum (L-Ring Drum) is a class monnolithic case is columniform Bulk plastic bucket, having with staving one step integral forming, cross-sectional plane on the top of this kind of bucket or two ends, the end, top is that ring is carried in solid supporting, because the cross sectional shape of support conveyor ring is gained the name as English alphabet L in its first generation product.The development of Bulk plastic bucket be along with the sixties HMW(high molecular weight)-high density polyethylene (HMwHDPE) resin suitability for industrialized production start.The strength under shock of HMwHDPE resin superelevation and melt strength, making to produce the production that can meet the Bulk plastic bucket of international carriage of dangerous goods packing requirements becomes possibility.German Mao Se companies in 1977 and BASF AG's connection platform successfully develop 220L L closed L ring plastic barrel, for HDPE Large Hollow Container opens gate widely using of chemical industry.
China started to test-manufacture 200L Plastic Drum in 1984, and at that time, Beijing plastic product factory had introduced BA200 type major blowing slush molding unit from Germany Beckum (BEKUM) company, produced 200L plastic bucket with cover and interior village bucket.After this Zhaozhou County, Heilungkiang plastic packing product factory, Jinan plastics nine factory, Qingyun County, Shandong plastic molding and processing plant have successively introduced similar equipment from the Ishikawa Dao Bomo company of German Ke Laobai mono-Kao Tesi (KRUPP-KAuTEX), Bei Kumu and Japan.But the resin raw material needed for machining large Plastic Drum is domestic at that time still can not be produced and dependence on import, expensive, also because Plastic Drum handling tool used is different from steel drum, the popularization of Bulk plastic bucket encounters difficulties.China Petroleum Chemicals Corporation in 1986 is the product aft-loaded airfoil problem solving the 4 cover 300kv'a ethylene units being about to go into operation, according to the investigation to foreign market and device fabrication producer. determine the BM201 type big blow molding unit arranged by Qilu Petroleum Chemistry Co. Inst. and equipment Imported From German EMH Company Mao Se company of plastic molding and processing plant of Jinling Petrochemical Co., produce the 200L L ring self-bearing type that can be used as international dangerous cargo transporting package containers to remain silent rigidity plastics bucket, thus the production level of Chinese large-sized Plastic Drum is brought up to a new height.
This Plastic Drum at least has one and is configured in the support conveyor ring that ladle bowl upper peripheral edge scope is suitable for barrel handler, can manufacture during manufacture according to different processes:
1. German patent DE-4,228, refer to a kind of L ring Plastic Drum in 112, as shown in Figure 1, the forming method of this L ring Plastic Drum Integratively formedly in blow molding process on staving, forms support conveyor ring, the shaping staving of left and right matched moulds, and one or two slide block moving up and down has been installed on half module, during type embryo inflation, define by the shaping bucket wall of sliding block flared section on half module, then when slide block closes up, the support conveyor ring of this partial material fusion compacting l-shaped;
In above-mentioned patent, the shortcoming of Plastic Drum is: this support conveyor ring and staving join domain easy fracture, and product is short for service life; In order to mold support conveyor ring simultaneously, make shaping staving two ends thick, intermediate thin, barrel body wall thickness ununiformity is even, and consumptive material is many, and in forming process, comprise left and right matched moulds and upper and lower matched moulds, the single product production cycle is long; During production, high to the requirement of equipment, special major blowing machine need be used, and equipment cost is high.
2. US Patent No.-3,394,747 refer to a kind of Plastic Drum, and staving and support conveyor ring are prefabricated into parts by this bucket respectively, are then welded to each other or bond together; US Patent No.-4,094,432 refer to a kind of Plastic Drum, and staving and support conveyor ring are arranged to detouchable parts by this bucket, and with bucket wall screw-threaded coupling;
In above-mentioned patent, the shortcoming of Plastic Drum is: because its staving and support conveyor ring are prefabricated into parts respectively, then combined by welding or bonding way, its complex process, production efficiency is low, and can find the problem that combines loosely when loading and unloading the fully loaded Plastic Drum of transport.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of firm in structure, uniform wall thickness and the plastic bottle of long service life, also provides a kind of preparation technology preparing above-mentioned plastic bottle.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of plastic bottle comprises a staving, the excircle of staving end face is provided with support conveyor ring, ladle body be circumferentially provided with two annular muscle; Its innovative point is: described support conveyor ring and staving are split-type structural, and described staving is combined into staving end face lock ring by opening hot by support conveyor ring.
Further, the excircle of described staving top surface areas has an annular groove, correspondingly, support conveyor ring inner periphery has an annular convex suitable with annular groove, and described support conveyor ring inlays lock ring on the excircle of staving end face.
Further, described annular groove is C font, and annular convex is in corresponding C font.
Further, the degree of depth of described annular groove is 18mm.
The invention also discloses a kind of preparation technology of above-mentioned plastic bottle, its innovative point is: first described preparation technology molds two annular muscle on staving, the annular groove of staving end face excircle and ladle body excircle on blow moulding machine; Then on injection machine, injection mo(u)lding goes out to support transport ring, when the support conveyor ring of forming is also in hot, utilize its ductility to be opened rear banding in the annular groove of staving end face excircle, be integrated with staving, and then obtained plastic bottle.
The invention has the advantages that:
Plastic bottle of the present invention, support conveyor ring and staving are split-type structural, staving is combined into staving end face lock ring by opening hot by support conveyor ring, solves the problem of support conveyor ring and staving calmodulin binding domain CaM easy fracture in traditional integral formula structure, improves the quality of product; Due to its split-type structural, during shaping staving, only need left and right matched moulds, the separate room of product is with short production cycle, improves the production efficiency of product, and the bucket wall of shaping staving is even simultaneously, and consumptive material is few, has saved material cost; During shaping support conveyor ring, adopt waste material in common injection machine injection mo(u)lding, expensive HMwHDPE resin need not be adopted, and do not need special equipment, reduce input cost and the material cost of equipment;
The annular groove of staving bottom surface of the present invention is C font, annular convex is in corresponding C font, and the degree of depth of annular groove is 18mm, strengthens the combination of support conveyor ring and staving, improve the steadiness of product structure and the quality of product, product meets GB18191-2000 standard after testing.
The preparation method of plastic bottle of the present invention, first blow molding goes out staving, then injection mo(u)lding goes out support conveyor ring, when support conveyor ring is hot, utilizes its ductility, open lock ring in the annular groove of staving end face, prepare plastic bottle, this technique is simple, low to the requirement of equipment, reduce productive costs, improve the production efficiency of product.
