Rolling structure of sheet grinder

This creation relates to a rolling structure of a thin plate grinder, especially one that can be adjusted to scrub thin plates of different thicknesses.

During the processing of the printed circuit board, the industry generally uses a thin plate grinder to remove the entire surface and burrs of the printed circuit board. Among them, there are at least two sets of horizontally juxtaposed first roller set and second roller set between the two side plates of the thin plate grinding machine, wherein the first roller set includes the first roller and the first pressed wheel corresponding to the top and bottom, the second roller set The roller group includes a second roller and a second roller corresponding to the upper and lower sides, and each roller has a roller brush on the outer periphery, so that when the printed circuit board passes between each roller and each roller, it can match a large amount of acid. Perform brush cleaning to remove excess copper foil on the upper and lower surfaces of the printed circuit board.

However, any of the above roller groups are fixed structures without any room for adjustment, and although each roller will automatically rise or fall due to the consumption of the roller brushes during the brushing process, so as to maintain the roller brushes and the pressed rollers. The gap between the rollers, but when grinding printed circuit boards with different thickness specifications, especially thicker sheets, due to the horizontal juxtaposition of the top of the first pressed roller of the first roller group and the top of the second roller of the second roller group On the same horizontal plane, even though the thin plate can pass through the gap between the first roller and the first pressed roller, the front end of the thin plate will still be pressed against the second pressed roller. wheel and cannot move forward for the scrubbing operation. Therefore, it is necessary to replace drums with different diameters, or use thin-plate grinding machines with different drum set specifications, which is not only inconvenient in replacement and use, but also increases material and processing costs.
