Description
Technical field
The utility model relates to plastic tube product line upper sealing device technical field, particularly relates to the seal ring on a kind of plastic tube product line.
Background technique
Existing plastic tube product line is primarily of control system, extruder, head, sizing cooling system, tractor, planet cutting device and tilting trestle composition, and wherein, sizing cooling system comprises vacuum shaping box and spraying cooling water tank; Shaping mainly being extruded by machine head port mould of plastic tube forms tube material embryo, then tube material indusium is shaped through vacuum shaping box and spraying cooling water tank, cools the size requirement reaching regulation.At present, on vacuum shaping box and spraying cooling water tank except mostly adopting Stamping Steel Ribbon or seal ring between casing and case lid and sealing, also need to seal at pipe outlet end in addition, it is normally from the seal ring of the lower corresponding size of monoblock General Purpose Rubber sealing material cutting, often be difficult to during sealing formalized and fix, seal operation is inconvenient, sealing effect is poor, and the processing time consuming effort of seal ring, there is out-of-flatness once cutting mouth to be just easy to produce slight crack or break, sealing effect is poor, and working life is short, and manufacture cost is large.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of structure simple, low cost of manufacture, easy for installation, long service life, the seal ring on the plastic tube product line of good sealing effect.
For achieving the above object, the utility model is by the following technical solutions:
Seal ring on a kind of plastic tube product line, it comprises seal ring body, described seal ring body is connected to form convex shape by bigger diameter end and miner diameter end, described seal ring body bigger diameter end end face is circumferentially provided with several mounting holes, in the middle part of described seal ring body, is provided with the axial passage passed for plastic tube.
Described seal ring body bigger diameter end end face and axial passage intersection are provided with the first chamfering.The design of the first chamfering, when plastic tube penetrates axial passage, can play the effect of guiding.
Described seal ring body bigger diameter end and miner diameter end outer side wall intersection are provided with the second chamfering.The design of the second chamfering, the stress that can reduce seal ring body bigger diameter end end face and axial passage intersection is concentrated, and can prevent from tearing.
Several mounting holes described are uniformly distributed circumferentially.The design of mounting hole, is convenient to seal ring fixing and location when mounted, can reduces the difficulty of installation, improve installation precision, thus improve sealing effect.
Described mounting hole is tapped hole.
Described seal ring body is by silica gel material integral injection molding.The silica gel material adopted has fabulous sealability, effectively can prevent from leaking, leaking gas, have good elasticity and crushing resistance, indeformable, heat resistance, winter hardiness, the advantage such as ageing-resistant; The design of integral injection molding, makes manufacturing process simple and convenient, can strengthen the toughness of seal ring, and make it be not easy produce crack or break, working life improves more than 10 times than conventional seals circle, greatly improves pliability and the sealing effect of seal ring.
The utility model adopts above technological scheme, when mounted, seal ring body bigger diameter end is fixed on the casing of vacuum shaping box or spraying cooling water tank, several mounting holes arranged by circumference are positioned, and utilize the locking elements such as bolt to be locked on casing by seal ring and flange plate, thus achieve vacuum shaping box or the effective sealing between spraying cooling water tank and the plastic tube produced, in process of production, when plastic tube is through seal ring, the axial passage of plastic tube and seal ring is interference fit, can effectively prevent from producing in plastic tube moving process leaking, gas leak phenomenon, due to the existence of seal ring body miner diameter end, the axial passage of seal ring is lengthened, thus improve sealing effect further.The utility model structure is simple, and low cost of manufacture is easy for installation, long service life, and have toughness strong, pliability is good, the advantages such as good sealing effect.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is further elaborated:
Fig. 1 is the seal ring schematic front view on the utility model plastic tube product line;
Fig. 2 is the seal ring schematic top plan view on the utility model plastic tube product line;
Fig. 3 is the seal ring scheme of installation on the utility model plastic tube product line.
Embodiment
As shown in one of Fig. 1-3, the utility model comprises seal ring body 1, described seal ring body 1 is connected to form convex shape by bigger diameter end 11 and miner diameter end 12, described seal ring body 1 bigger diameter end 11 end face is circumferentially provided with several mounting holes 111, in the middle part of described seal ring body 1, is provided with the axial passage 13 passed for plastic tube 2.
Described seal ring body bigger diameter end 11 end face and axial passage 13 intersection are provided with the first chamfering 14.The design of the first chamfering 14, when plastic tube penetrates axial passage 13, can play the effect of guiding.
Described seal ring body bigger diameter end 11 is provided with the second chamfering 15 with miner diameter end 12 outer side wall intersection.The design of the second chamfering 15, the stress that can reduce seal ring body bigger diameter end 11 end face and axial passage 13 intersection is concentrated, and can prevent from tearing.
Several mounting holes 111 described are uniformly distributed circumferentially.The design of mounting hole 111, is convenient to seal ring fixing and location when mounted, can reduces the difficulty of installation, improve installation precision, thus improve sealing effect.
Described mounting hole 111 is tapped hole.
