Leak-proof tyre glue spreader
The present invention relates to the glue sprayer of a kind of specialized equipment, particularly a kind of puncture-proof tire.
No. 97247890.6 utility model patents of China disclose that a kind of motor tire is anti-tie, the technical scheme of leakproof, and this scheme is coating one deck high viscosity, an elastomeric hot melt mending-leakage material in tire.Effect anti-tie, leakproof that this scheme has reached; But in tire, apply application of anti-leakage layers by manual fully, can not adapt to the needs of this technology large-scale promotion, and still not finish the machinery and equipment of this technology in the prior art.
The invention provides a kind of equipment: leak-proof tyre glue spreader to vacuum tire (no inner bag tire) spraying hot melt mending-leakage material.This glue sprayer can be finished the processing technology that high viscosity, high resiliency hot melt mending-leakage material evenly is coated to tire inner surface, in the course of processing, can control bondline thickness on demand, spray glue-line thickness degree of uniformity and can be controlled in certain error limit, but spray glue width regulated at will makes the technical requirements that can reach the puncture-proof tire each side behind the tyre glue-jetting.
The technical scheme of finishing the foregoing invention task is as follows: leak-proof tyre glue spreader, be provided with the rolling clamp that drives by engine, and be provided with the glue shower nozzle simultaneously, be connected to pipeline behind the shower nozzle, pipeline is connected with the equipment of supply glue.Here said " by the rolling clamp of engine drive " can be: be provided with the rotating disk that is driven by engine, anchor clamps are housed on the rotating disk.Also can not establish rotating disk, and anchor clamps are contained on the S. A., this is equal to " anchor clamps are housed on the rotating disk ".Said anchor clamps are used for fixing motor tire, and it can be fixed on tire on the rotating disk, and the oral area of tire is drawn back.Said the equipment of glue " supply " can be fluid reservoir, bhatta, also can be pressing mechanism etc. other equipment of glue is provided.Said pressing mechanism can be an oil cylinder, pressure cylinder or pressurization screw rod etc., and also the potential energy that can utilize height to put fluid reservoir pressurizes to glue.Its optimal design is: between fluid reservoir or bhatta and shower nozzle, be provided with pressing mechanism, between pressing mechanism and fluid reservoir or the bhatta, between pressing mechanism and the shower nozzle, be provided with check valve.This mechanism plays suction, presses two-way function in spray glue process: pressing mechanism is drawn glue when spraying from fluid reservoir at every turn, is sent to shower nozzle again.Between pressing mechanism and the fluid reservoir, between pressing mechanism and the shower nozzle, also filter can be set.The pressing mechanism place can be provided with quantitative mechanism, except that for the shower nozzle pressurization, also plays the quantitative utensil of glue simultaneously.(or rotating disk place) also can be provided with regulating mechanism and stop mechanism at the rolling clamp place.The optimal design of anchor clamps is that anchor clamps are made up of separate two parts, holds the both sides of tire respectively, its oral area is drawn back and vacates working space to shower nozzle.
The present invention provides specialized equipment for the processing puncture-proof tire, this equipment can be finished high viscosity, high-strength hot casting-on are leaked the processing technology that material evenly is coated to tire inner surface, in the course of processing, can control bondline thickness on demand, spray glue-line thickness degree of uniformity and can be controlled in 10% the error limit, but spray glue width regulated at will reaches the technical requirements of puncture-proof tire each side.
Now be described further with embodiment in conjunction with the accompanying drawings.
Fig. 1 is embodiment 1 structural representation.
Embodiment 1, and with reference to Fig. 1: rotating disk 1 by main motor 2 driven rotary, is equipped with anchor clamps by transmission device on the rotating disk, and anchor clamps are made of clip plate 3 and arc arm-tie 4.Be provided with glue shower nozzle 5 simultaneously, shower nozzle is connected with oil cylinder 8 by pipeline 6, check valve 7.The pressurization screw rod 10 that is driven by spray glue motor 9 is equipped with in the oil cylinder top, and travel switch 11 is housed on the screw rod 10.Glue in the fluid reservoir through filter 12, check valve 13, leads to oil cylinder.When tire 15 installs on the glue sprayer, hold the both sides of its oral area respectively, the tire oral area is drawn back, and be fixed on the rotating disk, rotate with rotating disk by clip plate and arc arm-tie.The pressurization screw rod rises under the drive of motor 9, and glue is inhaled into oil cylinder 8 through filter 12 and check valve 13; When screw rod descends with glue through check valve 7, pipeline 6 and shower nozzle 5, be sprayed onto the inside face of tire.The centnifugal force that the tire rotation produces is evenly distributed glue.Along with the reduction of temperature, glue solidifies, and becomes application of anti-leakage layers.Travel switch 11 is quantitative mechanisms, the stroke of its scalable pressurization screw rod, thus change the glue amount, the thickness of control sprayed coating.The glue amount can be regulated between 0~1000ml.Same tire can once spray to be finished; Also can repeatedly spray and finish.The pressure of oil cylinder is by glue viscosity and spraying rate decision.The rotating speed of rotating disk is also by glue viscosity and spraying rate decision.Regulate the distance between shower nozzle and the tire, can change the spraying width of glue in tire.On the axle of rotating disk, drg 14 is housed.Pipeline in this example, shower nozzle etc. are located, and are equipped with heat preservation mechanism (available parcel heat-insulation layer or heating arrangement is set be incubated).The rotating speed of rotating disk can be adjusted between 100~600 commentaries on classics, makes the linear velocity of tire reach 1~12 meter per second.Change rotating disk or shower nozzle, the design can be fit to the spray glue processing of any tire.Peel strength between application of anti-leakage layers and the tire can reach more than the 300N, can prevent gas leakage, prevent to blow out when tire be stabbed.
