Specifically, the spring 54 is a disc spring 54. In the damping adjustment assembly 50, the adjustment wheel 53 is moved on the transmission shaft 31 by rotation to adjust the spring force of the spring 54 between the adjustment wheel 53 and the positioning plate 52. Because the second friction plate 521 arranged on the positioning disc 52 is attached to the first friction plate 511 arranged on the connecting sleeve 51, the connecting sleeve 51 is connected with the driving assembly 60, and the positioning disc 52 is clamped on the transmission shaft 31, the friction force between the first friction plate 511 and the second friction plate 521 is increased when the elastic force of the spring 54 is increased; similarly, when the spring 54 has a reduced elasticity, the friction between the first friction plate 511 and the second friction plate 521 is reduced.

Therefore, the steel strip coil 80 generates a low speed mode when in large size and a high speed mode when in small size, so that the unwinding speed of the packed steel strip is stable, and the smooth operation of the steel bar binding operation is ensured.
In this embodiment, the driving assembly 60 is a motor, and the power output end thereof is connected with the first end of the connecting sleeve 51 through a coupler; the motor is electrically connected with the controller and is controlled by the controller to operate.
