When the diameter of the cable is different, the worker can adaptively adjust the height of the bracket 41 so that the pressing roller 45 presses the cable against the conveyor belt 2 when the cylinder 42 is extended.

In order to reduce the pressure of the cable during conveying and protect the cable, an expansion link 46 is arranged between the support frame 43 and the pinch roller frame 44, the expansion link 46 comprises sleeves which are sleeved with each other, a first spring 47 is sleeved outside one of the sleeves, one end of the first spring 47 is fixed on the pinch roller frame 44, the other end of the first spring 47 is fixed on the other sleeve, and the pinch roller frame 44 tends to be far away from the support frame 43 due to the elasticity of the first spring 47. When adjusting the pressure roller 45, the worker can appropriately control the degree of compression of the pressure roller 45, so that the first spring 47 is slightly compressed. Therefore, the pressing roller 45 has elasticity, so that when the cable slightly jumps, the cable can be stably conveyed, and the integrity of the cable can be protected by swinging along with the cable.

Referring to fig. 1 and 3, if the cable is difficult to be transported due to a failure at another position, the traction device for cable production can be stopped in time while the cable is stopped, thereby protecting the cable.
