[0026] The present application redesigns the curling drive device according to the actual situation on site, cancels the traditional sprocket transmission method, and sets a motor 14 and a reducer 4. The motor 14 directly drives the transmission shaft 3 to rotate after the reducer 4, and then drives the driving roller 1 to rotate to curl the rubber. The structure is simple, the failure rate is low and it is easy to maintain. The rubber curling process is relatively stable, which greatly improves the quality and output of rubber products, runs smoothly, and meets production requirements.

[0027] Specifically, the transmission shaft 3 in the present application passes through the reducer 4 and is key-connected with the gear structure inside the reducer 4, which is equivalent to replacing the output shaft in the reducer 4 with the transmission shaft 3, so that the motor 14 is decelerated through the reducer 4 and directly drives the transmission shaft 3 to rotate.

After the detection control component detects that the tooling wheel is in place, it controls the motor 14 and the cylinder 9 to operate and drive the drive roller 1 to rotate.

[0049] When the tooling vehicle enters the curling station, the cylinder 9 is in a retracted state and the motor 14 is in a stopped state.
