Background technology
Automobile is as traffic, the instrument of riding instead of walk, and every Year's consumption increases severely, and tire there will be by situation about puncturing under steam, occurs unsafe condition.Existing solution sprays one deck high viscosity, elastomeric macromolecule memory synthetic size by tyre glue-jetting machine at the inner surface of tire.When tire is punctured by nail or other puncture things, this macromolecule memory synthetic size can will puncture mouthful shutoff rapidly thus play the effect of leakproof.Existing tire automatic glue sprayer comprises colloidal sol, defeated glue, glue spraying, tire detent mechanism and cooling body etc.
Chinese patent CN 103302007A, discloses a kind of comprehensive glue spraying method for the manufacture of being folded without breaking puncture-proof tire, comprises the following steps: 1) with clear water by tire inner wall wash clean; 2) tire of wash clean is fixed on many specification tyre chuck of tire dynamic and balance and uniformity detection; 3) with tire dynamic and balance and uniformity detection, dynamic balancing adjustment is carried out to tire, rotate test, measure non-equilibrium site and weight, the position of measuring is fixed and measures equiponderant fluid sealant, carry out rotation test again, if imbalance carries out above operation again, until dynamic balancing; 4) with certain speed (relevant with the thickness of glue spraying) rotating tire's, with a shower nozzle, fluid sealant is sprayed into tyre surface inside tire, stop after certain hour; 5) tire is unloaded from movement of the foetus balance and uniformity detection, and with nitrogen, tire is cooled; 6) kept flat by tire, the shower nozzle rotated along sidewall with, carries out glue spraying to sidewall, has sprayed a rear flank, cooled with nitrogen to tire.Then tire is turned over turnback, then glue spraying is carried out to another side, with nitrogen, tire is cooled again after having sprayed; 7) again dynamic balancing detection is carried out to tire, if imbalance carries out the operation of step (3), until dynamic balancing.
Above-mentioned tyre glue-jetting technique, needs manual overturning tire, increases workload, needs checkout gear and corresponding conversion calculations module to calculate glue spraying amount, complex structure.
Summary of the invention
Technical problem to be solved by this invention is: for the deficiencies in the prior art, and provide a kind of tyre glue-jetting technique, automatic coating, spray-on coating is more even.
For achieving the above object, the invention provides a kind of tyre glue-jetting technique, comprise the steps: 1) use sander grinding tyres inwall; 2) tire of having polished is fixed on tyre glue-jetting machine detent mechanism; 3) tyre glue-jetting machine detent mechanism is with certain rotating speed rotating tire's; 4) start the spraying of full spray first, spray of tire inner surface is whole; 5) cooling body air-supply cooled inner wall; 6) start the spraying of full spray second, spray of tire inner surface is whole; 7) cooling body air-supply cooling tire inner wall; 8) start full spray the 3rd road spraying, spray of tire inner surface is whole; 9) tyre glue-jetting machine detent mechanism continues rotating tire's; 10) cooling body air-supply cooled inner wall; 11) full jet mould formula is closed; 12) half spray first spraying is started, bottom spray of tire inner surface; 13) cooling body air-supply cooled inner wall; 14) half spray second spraying is started, bottom spray of tire inner surface; 15) cooling body air-supply cooling tire inner wall; 16) half spray the 3rd road spraying is started, bottom spray of tire inner surface; 17) after tyre glue-jetting machine detent mechanism continues rotating tire's certain hour; 18) cooling body air-supply cooled inner wall.
Further, step 5), 7) and step 13), 15) cool time is 150-160s, step 10), 18) cool time is 360s-420s.
Meanwhile, step 9) and step 17) in, tyre glue-jetting machine detent mechanism rotating tire's 30s-35s.
Step 4), 6), 10), 12), 14) and step 18) tire rotational speed is 1 revolutions per second, step 8) and step 16) tire rotational speed is 3 revolutions per seconds.
Tyre glue-jetting technique of the present invention, for tire inner surface all independent glue sprayings with bottom surface, after whole three sprayings of inner surface after cooling, bottom coated inner face, for the situation more subjecting to bottom tire inner surface to stab, emphatically bottom coated inner face, after spraying, tire is kept to continue to rotate, glue is made evenly to be applied to tire inner surface under the effect of revolving force, spraying is more even, and spray-coating surface is more level and smooth, improves coating quality and spraying effect.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, tyre glue-jetting technique of the present invention is described in further detail.
Embodiment one
As shown in Figure 1, tyre glue-jetting technique of the present invention, comprises the steps: 1) use sander grinding tyres inwall; 2) tire of having polished is fixed on tyre glue-jetting machine detent mechanism; 3) tyre glue-jetting machine detent mechanism is with certain rotating speed rotating tire's; 4) start the spraying of full spray first, spray of tire inner surface is whole; 5) stop the rotation tire, cooling body air-supply cooled inner wall; 6) rotating tire's, start the spraying of full spray second, spray of tire inner surface is whole; 7) stop the rotation, cooling body air-supply cooling tire inner wall; 8) rotating tire's, start full spray the 3rd road spraying, spray of tire inner surface is whole; 9) tyre glue-jetting machine detent mechanism continues rotating tire's; 10) stop the rotation tire, cooling body air-supply cooled inner wall; 11) full jet mould formula is closed; 12) rotating tire's, starts half spray first spraying, bottom spray of tire inner surface, namely arrives tire R Angle Position; 13) stop the rotation, cooling body air-supply cooled inner wall; 14) rotating tire's, starts half spray second spraying, bottom spray of tire inner surface; 15) stop the rotation, cooling body air-supply cooling tire inner wall; 16) rotating tire's, starts half spray the 3rd road spraying, bottom spray of tire inner surface; 17) tyre glue-jetting machine detent mechanism stops after continuing rotating tire's certain hour; 18) cooling body air-supply cooled inner wall.
