Claim 7:
8. A winding method for use in FRP tank production using the winding assembly according to claim 1, wherein the method comprises the following steps:
S1: for conducting winding work, first of all, controlling the two supporting bases to slide close via the two air cylinders, so that the rotation shafts and the locking seats on the two supporting bases are inserted into a tank body, thereafter, starting the first electromagnetic plates and the normally open solenoid valves, after energizing, the normally open solenoid valves will be automatically closed, closing the air pipes, after energizing, the first electromagnetic valves will generate magnet and repulse the first permanent magnetic plates at both sides, so that the two rivet holders drive the suction discs to stick against an inner surface of the tank body, meanwhile, the suction discs will be absorbed on the tank body to promise locking stability;
S2: after locking the tank body, fixing a side of plastic film to be wound on the tank body, thereafter, starting the drive motor, with transmission collaboration of the bevel gear component, the drive motor will drive the rotation shafts to rotate, the rotation shafts will drive the tank body to rotate, the tank body during rotation will wind the plastic film, during winding, starting the dust collector and the dust collector will suck dust on and clean a surface of the plastic film via collaboration of the dust collector, the corrugated telescopic tubes and the dust suction chamber on the dust suction seat; and
S3: when a weight of the fixing seats become higher due to vibration or winding of the plastic film on the tank body, and the fixing seats move, the at least one sliding block on the at least one sliding rheostat will move synchronously, when the at least one sliding rheostat moves downwards, electric resistance entering the second electromagnetic plates will be reduced, at this time, electric current flowing into the second electromagnetic plates will increase, magnet performance of the second electromagnetic plates will increase, the second electromagnetic plates will repulse the second permanent magnetic plates, the gear rods will move, with transmission cooperation of the transmission gears, the threaded supports will rotate, the dust suction seats will move downwards automatically so as to maintain a gap to the tank body, similarly, when the at least one sliding block on the at least one sliding rheostat moves upwards the dust suction seats will move upwards automatically.
