[0133] The utility model provides a production line, which comprises a conveying line body, an installation station arranged beside the conveying line body and a friction-adjustable deceleration device arranged in front of the installation station for decelerating the conveyed workpiece.

[0134] Specifically, in this embodiment, the conveyed workpiece is a process plate;

[0135] When in use, the two strip belts transfer the force to the rotating wheel 3 by contacting the process board. The adjusting nut 12 acts on the spring 11, and acts on the friction block 10 through the spring 11. The friction block 10 directly acts on the rotating wheel 3 to slow it down through friction, thereby achieving deceleration of the process board transportation. The size of the friction force can be adjusted by adjusting the nut 12.
