Description
Technical Field
[0001] This application relates to the technical field of ceramic ball processing, and particularly to an automatic feeding device for ceramic ball processing. Background Art
[0002] Ceramic balls are a kind of precision ceramic products, with high hardness, high wear resistance, high compressive strength and good chemical stability. They are widely used in bearing manufacturing, especially in high-speed, high-temperature or strongly corrosive environments. They are also used to make valve balls, sealing components of pumps, medical devices and dental applications, etc. The preparation process of ceramic balls is roughly raw material selection, raw material powder treatment, forming, sintering and grinding.
[0003] When processing ceramic balls, an automatic feeding device is usually used to achieve automatic feeding of ceramic balls. Currently, an existing automatic feeding device includes a feeding tank body that is rotatably and obliquely arranged. The feeding tank body stores ceramic ball raw materials. The discharge end cover of the feeding tank body has a plurality of discharge cavities distributed around the axis. The inner wall of the edge of the discharge end cover is provided with feeding holes corresponding to and communicating with each discharge cavity. The outer wall of the discharge end cover is coaxially provided with a discharge pipe communicating with each discharge cavity. By driving the motor to drive the feeding tank body to rotate, the ceramic ball raw materials roll inside the tank body. When the feeding hole is at the bottom, the ceramic balls enter the discharge cavity through the feeding hole. As the tank body rotates, when the discharge cavity with ceramic ball raw materials gradually reaches a higher position, the ceramic balls fall to the inner cavity bottom of the discharge cavity due to their own weight and are automatically discharged through the discharge pipe arranged at the axial center position of the discharge end cover, and are transferred to the processing equipment. When the empty discharge cavity continues to move below the tank body, it automatically feeds materials, and discharges materials as the feeding tank body rotates, continuously realizing automatic feeding operation.
[0004] However, with the continuous rotation of the feeding tank body, the ceramic ball raw materials tumble and rub against each other inside the feeding tank body, resulting in wear on the surface of the ceramic ball raw materials, increasing the loss amount of the ceramic ball raw materials. Therefore, further improvement is needed. Utility Model Content
