Description
Technical field
The present invention relates to a kind of holding bottle of liquefied petroleum, relate in particular to a kind of plastic inner container winding gas cylinder and manufacturing process thereof.
Background technique
The excellent properties such as plastic inner container winding gas cylinder is lightweight with it, intensity is high, corrosion-resistant, in order to substitute traditional metal gas cylinder, have broad prospects.But be subject to the restriction of plastics self intensity, be made up of metallic material conventionally the air outlet of plastic inner container gas cylinder, because modulus and the rates of thermal expansion of bi-material differ greatly, make the binding site of bi-material can occur because rigidity is discontinuous crack in the time suffering cyclic loading; Under the effect of ambient temperature, can produce thermal stress, also can make connecting part occur crackle, thereby cause gas cylinder gas leakage.
Sealing force between the metal bottle neck of existing plastic inner container winding gas cylinder is on the market the power by self-assembling formation in moulding, is difficult to control, and often causes sealing reliability inadequate, easily produces and leaks.While accessory structure is complicated, complex technical process, has reduced manufacturing efficiency.
Summary of the invention
The utility model is inadequate for plastic inner container winding gas cylinder bottle sealing reliability in prior art, easily produces the deficiency of leaking, and a kind of novel plastic inner container winding gas cylinder and manufacturing process thereof are provided.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Plastic inner container winding gas cylinder, comprise body and bottleneck, bottleneck comprises metal bottleneck, metal bottleneck outside is provided with moulding, metal bottleneck and moulding vertically highly consistent, the outside, below of metal bottleneck is provided with annular boss, annular boss upper surface is the inclined-plane that dips down, moulding is circular, inside annulus, the outer shape of shape and metal bottleneck is coincide, the top of the relative annular boss of moulding is provided with outer body, the upper surface of the outer body inclined-plane that dips down, outer body is reduced to 3mm-20mm gradually with radial thickness, the lower surface of outer body is provided with embedded rings, the both sides of embedded rings are provided with seal ring, the plastic inner container that the outer side surface of the below of the outer body of moulding is blowing, body top, outer is provided with winding layer, winding layer is distributed in plastic inner container outside, by plastic inner container together with metal bottle open tightening, the outside of metal bottleneck is all enclosed with moulding, the upper outer of metal bottleneck is provided with outer and protrudes, and the protrusion of outer is embedded in moulding, and the upper outer of moulding is provided with outer and protrudes.Whole bottleneck portion only contains integrally manufactured metalwork and moulding, there is no other Component, has reduced the manufacturing of part, and the cooperation space of avoiding multiple parts to produce causes gas leakage, has reduced the technique that processing is installed.
The bottleneck of whole plastic inner container winding gas cylinder is only combined by metal bottleneck and moulding, has reduced the installation of Component, and moulding is molding and forming, and the error of having avoided size makes cooperation between the two tightr.Metal bottleneck is consistent with moulding height, and the outside of metal bottleneck is all enclosed with moulding, makes the stressed more even of metal bottleneck, better tightness.Annular boss is embedded into the inner side of moulding, makes combination between the two more tight, and the upper surface of inclination is understood because the spring-back force of plastic deformation makes contact more tight moulding in shaping plasticized process.The annular boss of the outer body complexed metal bottleneck of moulding stretches out, and makes moulding thickness everywhere approximately consistent, makes stress equalization.The embedded rings of outer body lower surface is used for connecting injection moulding inner bag, makes the connection of injection moulding inner bag and bottleneck tightr.The attenuation gradually of the thickness of outer boss is thinned to 3mm-20mm always, and concrete thickness determines according to the size of winding gas cylinder.The arrangement of seal ring makes the tightness of whole bottle better.Outer field winding layer, makes whole winding gas cylinder as an integrated gas cylinder, improves anti-pressure ability and the sealing of gas cylinder.
As preferably, the upper outer of metal bottleneck is provided with outer and protrudes.The protrusion of outer is embedded in moulding, makes chimeric connection between the two tightr, there will not be and gets loose.
As preferably, the upper outer of moulding is provided with outer and protrudes.Outer herein protrudes along with radially abduction is protruded in the outer of metal bottleneck, ensured that moulding is everywhere in thickness situation unanimous on the whole, and bottle mouth position forms the plan view of N limit shape, more convenient when bottleneck is coordinated with other accessories installations.
As preferably, the outer of the upper outer of moulding is protruded between winding layer and is formed bottleneck.Convenient carrying and fastening, is convenient to be connected with other equipment.
As preferably, the interior side-lower radial dimension of metal bottleneck is less than top radial dimension.Metal bottleneck inner side needs and other equipment connections, makes Inner Dimension reserved enough large.
As preferably, the inside front of metal bottleneck is provided with internal thread.Be used for connecting other equipment.
Manufacture the technique of above-mentioned arbitrary described plastic inner container winding gas cylinder, metal bottleneck is placed in the mold cavity of injection machine, moulding directly tightly fits in together by molding and forming and metal bottleneck, and then the product of injection formed is seated on blow-moulding machine, and seal ring is enclosed within respectively to the embedded rings both sides of moulding, complete the blow moulding and forming of plastic inner container, finally winding layer is wound into plastic inner container outside, and fastening metal bottleneck.Whole technological process is simple, does not need artificial cooperation to install, and has avoided the appearance of alignment error.
According to the plastic inner container winding gas cylinder of technological scheme of the present invention, the accessory part of bottleneck is few, and the sealing of bottle mouth of gas cylinder is high, and bottleneck is difficult for producing leakage.
