[0040] Example 2

[0041] Based on Example 1, in order to assist in limiting and conveying the material conveyed on the conveying assembly, and to prevent the material from shaking or shifting during conveying.

[0042] like Figure 6 As shown, in this embodiment, the limiting mechanism 400 includes two C-shaped plates 450, which are slidably connected to two connecting holes 211 respectively. Two conveying rollers 451 are rotatably connected inside the C-shaped plates 450, and conveyor belts 452 are drively connected to the outer sides of the two conveying rollers 451. A motor 453 is fixedly connected to the C-shaped plates 450, and the output end of the motor 453 passes through the side wall of the C-shaped plates 450 and is fixedly connected to the corresponding conveying roller 451. An adjustment assembly is provided on the outer sides of the two C-shaped plates 450. The adjustment assembly includes: a connecting shell 410, a motor 420, a C-shaped rod 430, and two L-shaped plates 440.

The width of the L-shaped plate 440 is less than the width of the connecting shell 410, and the length of the chamfered plate 450 is the same as the length inside the connecting hole 211.

[0043] In specific implementation, by starting motor 420, the bevel gear 421 is driven to rotate. The bevel gear 421 and bevel gear 432 mesh, causing the bidirectional lead screw 431 to rotate. This causes the two L-shaped plates 440 and the two C-shaped plates 450 to move to appropriate positions. The two conveyor belts 452, which have moved to appropriate positions, facilitate the limiting of materials. By starting motor 453, the corresponding conveyor rollers 451 are driven to rotate, causing the two conveyor belts 452 to rotate. When the moving speed of conveyor belt 221 and the two conveyor belts 452 are the same, the rotating conveyor belts 452 facilitate the movement of materials and prevent the materials from shaking or shifting during transport.
