Description

Technical Field

[0001] This invention relates to the field of crystal processing equipment, and in particular to a feeding mechanism for a crystal surface grinding and polishing machine. Background Technology

[0002] Currently, the feeding process of crystal grinding and polishing machines mainly involves two steps. The first step is to discharge the material by shaking the material box, and the second step is to position the blank by controlling the opening and closing of the bushing. In the first step, the material box needs to shake continuously for a period of time to complete the discharge. The subsequent transfer equipment needs to wait after each transfer, which reduces the overall processing effect of the machine. In the second step, the opening and closing of the bushing is driven by the support sleeve shaft to rotate the support sleeve teeth set on it. The contact area between the support sleeve teeth and the bushing is small, and the pressure on the contact part of the bushing is high, resulting in a high wear rate of the bushing during production. The above problems result in low feeding efficiency of existing grinding and polishing machines, as well as high equipment operation and maintenance costs. Summary of the Invention
