The automatic tire anti-air leakage coating spraying device according to claim 8, wherein in use, the motor drives the front-most roller to rotate through the transmission mechanism coupler and the speed reducer and drives the rest rollers to rotate through the transmission belt, so that all the large rollers are driven to rotate, and the large rollers drive the tire to rotate;
when the tire reaches between the positioning baffles, the positioning baffles have guiding function and can stretch and retract under the cooperation of the double crank pieces and the spring suspension, the spring suspension applies pressure to the tire to complete centering, and in the process, the small roller rotates to reduce friction between the tire and the positioning baffles;
the servo motor drives the ball screw to rotate through the lifting mechanism coupler, the ball screw and the auxiliary screw are mutually matched to drive the lifting arm to descend, the lifting arm drives the clamp shaft to descend through the rotating shaft motor, the stepping motor drives the motor shaft and the clamping mechanism coupler, the worm is driven to rotate through the bearing fixing piece, the worm drives the turbine to rotate, the turbine drives the driving gear to rotate through the shaft and the bearing retainer ring to drive the driven gear to rotate, the hard grabbing plate grabs the centered tire, and the external air pump charges the air bag through the air valve, so that the hard grabbing plate reliably clamps the tire;
along with the rising of the lifting arm and the action of the rotating shaft motor, the tire is lifted and turned over to the injection range of the nozzle, and the nozzle ejects the organic high polymer conveyed by the pipeline, the extruder and the nozzle to the inner wall of the tire to form an air leakage preventing coating;
along with the descending of the lifting arm and the action of the rotating shaft motor, the tire is placed on the large roller in a descending and overturning mode to be transported to the next working procedure, and therefore circulation is achieved, and automatic spraying of the tire air leakage preventing coating is achieved.
