[0036] The use process of the winding and coating device of the anticorrosive composite tape of this bending pipe winding machine is: the driving device drives the driven wheel 3 to drive the rotary disc 1 to rotate, and the polyethylene composite tape is continuously output from the belt conveyor 2 and passes through the tension control device The pressing rod 516 in 5 passes through the heating shell 401 of the heating device 4 at the same time, and the polyethylene composite tape 8 is pre-heated by the heating device 4; the heated polyethylene composite tape 8 is continuously wrapped around the elbow 7; At this time, the speed regulating motor 508 is turned on, and the friction wheel 504 is driven to rotate by the speed regulating motor 508. The roller groove formed between the front friction roller 505 and the rear friction roller 506 of the friction wheel 504 is the same as the annular boss 502 and the limit boss 503 and the inner surface of the hub 501, on the inner ring of the wheel 501, a step contact surface with a high front end and a low rear end is formed, in close contact; under the condition of continuous rotation of the rotary disc 1, the polyethylene composite belt 8 is coiled on the feeding wheel When the tension of the polyethylene composite tape 8 becomes greater, the pressure rod 516 will move downward, and the toggle plate 514 and the connecting plate 513 will act in conjunction with each other. , Rotates around the pin shaft 515 like a lever, so that the speed regulating motor 508 and the friction wheel 504 move upwards. At this time, the contact pressure between the friction wheel 504 and the inner surface of the hub 501 increases, and the friction is intensified. The power is transmitted to the belt feeding wheel 2 through the friction wheel 504 to speed up the belt feeding speed, thereby reducing the tension of the polyethylene composite belt 8; when the tension of the polyethylene composite belt 8 becomes smaller, the pressing rod 516 will move upward, and the toggle plate 514 and The connecting plate 513 rotates around the pin shaft 515 like a lever through the linkage function, so that the speed regulating motor 508 and the friction wheel 504 move down, the contact pressure between the friction wheel 504 and the hub 501 is reduced, the friction effect is weakened, and the speed regulating motor 508 The rotation of φ is no longer transmitted to the belt feeding wheel 2 through the friction wheel 504, thereby reducing the belt feeding speed and increasing the tension of the polyethylene composite belt 8;

[0037] Under the condition that the tension control device 5 of the polyethylene composite tape 8 controls the proper tension, the driving motor 601 is turned on at the same time, and the rotary striking roller 608 contacts the surface of the polyethylene composite tape 8 being wrapped on the elbow 7, and the motor 601 is driven. The driving sprocket 606 is driven to rotate, and the driven sprocket 607 is driven to rotate through the chain drive. The driven sprocket 607 drives the rotary striking roller 608 to rotate. While the striking roller 611 in the rotary striking roller 608 rotates, The polyethylene composite tape 8 on the elbow 7 is beaten to eliminate the air bubbles between the polyethylene composite tape 8 and the elbow 7, thereby improving the bonding strength between the polyethylene composite tape 8 and the elbow 7; the above process is The use process of the winding and coating device of the anticorrosive composite tape of the bending pipe winding machine.
