As shown in fig. 3, when the control device 5 employs a cylinder, the friction member 4 can be driven to swing to move the friction member 4 closer to or away from the driving roller 3 by extending and retracting the cylinder forward and backward.
In some embodiments of the present application, two friction members 4 are provided at predetermined positions of the conveyor line; two friction members 4 are located on either side of the drive roller 3, each friction member 4 being connected to a control device 5.
