Description

TECHNICAL FIELD

[0001] The application relates to a rim processing device, in particular to a rim blank collecting mechanism. BACKGROUND

[0002] A rim is generally circular and is a component of a wheel, which, together with an axle, spokes, an inner tube and an outer tube, forms a wheel system. China is a large country of bicycles and electric bicycles, and therefore a large number of manufacturers are bound to be established to meet the needs of production and life of the society.

[0003] However, due to the circular structure of the rim, enterprises often encounter problems of unreliable stacking and classification in a series of processing procedures. In particular, after polishing, if the rim is stacked and stacked without attention, scratches will be caused. At the same time, due to the structure of the rim, it is difficult to stack and place multiple rims one above the other, which affects the production of enterprises.
