As shown in fig. 3, the roller 21 may be a solid structure, and when the solid structure is adopted, the weight is increased, so that the friction force of the roller 21 is enhanced, and the driving device needs to increase the acting force when the roller 21 is driven to rotate. In order to solve the above problem, in the present novel usage, one of the end surfaces of the roller 21 is formed with an accommodating groove 210 inward, and an installation sleeve 211 is coaxially arranged in the accommodating groove 210, so that the roller 21 is light in weight as a whole, and further reduces friction.

When a workpiece is placed on the conveyor belt 20, the workpiece applies an acting force to the conveyor belt 20, and if there is no workpiece capable of providing support between the conveyor belts 20, the acting force will deform the conveyor belt, and the workpiece may jump on the conveyor belt, which affects the conveying stability and may even cause the workpiece to fall and be damaged.
