Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to solve the defect that the conventional rim cannot be automatically discharged from a hanger, the invention particularly provides a rim discharging mechanism which can realize automatic discharging of the rim and has high automation degree. To further illustrate the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:

referring to fig. 1, a rim blanking mechanism comprises a wheel hanging device 1 and a blanking device 2.

The wheel hanging device comprises a hanging frame 1-1, a hanging frame 1-2, a lower ejector rod 1-3, an upper pressing roller 1-4 and a lower carrier roller 1-5. The lower end of the hanger is fixed with the hanger, and in the embodiment, the hanger is connected with the hanger through a fastening bolt. The hanger is provided with a sliding groove extending in the vertical direction from top to bottom, and a roller shaft capable of sliding along the sliding groove is installed in the sliding groove. The roller shaft is provided with the upper compression roller through a bearing.
