[0023] 7. The gap between the limiting wheel and the conveyor belt is m, 0<m≤5cm. This setting can meet the limiting and guiding requirements for polishing luggage leather of different thicknesses.

[0024] 8. The piston shaft is extended and retracted in the movable cavity, so that the limiting wheel can have a certain amount of extension and retraction in the vertical direction, which can meet the limiting and guiding requirements of luggage leather materials of different thicknesses.

[0025] 9. The deformation of the spring is used to realize the directional force on the limiting wheel, so as to realize the limiting and squeezing effect of the limiting wheel on the luggage leather material, improve the limiting and guiding effect of the limiting wheel on the side of the luggage leather material, and avoid the side of the luggage leather material from warping.
