Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a lifting and lowering regulating device for a rubber-coated pressure roller. Background Art

[0002] With the development of the PCB industry, there are more and more PCB boards with different thicknesses. Volcanic ash grinding equipment is mainly used in the pre-treatment of outer layers, solder mask, and dry film. When grinding the board, the height of the upper rubber pressure roller will be raised according to the thickness of the board to facilitate the board passing and prevent the PCB board from being stuck in the equipment cavity and causing production abnormalities. The conventional processing method is that when producing PCB boards of different thicknesses, the operator first measures the thickness with a caliper and manually adjusts the height of the upper rubber roller according to the thickness. This method is relatively cumbersome and will reduce production efficiency. Utility Model Content
