Thin plate grinding machine rolling structure

Abstract

The invention relates to a thin plate grinding machine rolling structure. The thin plate grinding machine rolling structure is fixed between a first side plate and a second side plate which are opposite to each other of a thin plate grinding machine, the thin plate grinding machine comprises a second brush grinding set and a first brush grinding set, the first brush grinding set comprises a firstback pressure wheel and a first roller which correspond to each other up and down, and thin plates passes between the first back pressure wheel and the first roller; one end of the first back pressurewheel is connected with a first lifting mechanism, the other end of the first back pressure wheel is connected with a second lifting mechanism, and the first lifting mechanism and the second liftingmechanism drive the two ends of the first back pressure wheel to move up and down respectively so as to adjust the distance between the bottom end of the first back pressure wheel and the top end of the first roller. According to the thin plate grinding machine rolling structure, by adjusting ascending and descending of the first back pressure wheel, the distance between the first roller and the first back pressure wheel is increased or decreased so as to adapt to thin plates of different thickness specifications, the machining process of the thin plates can be more convenient, and meanwhile the material and labor cost for material replacement is reduced.

Description

technical field [0001] The invention relates to the technical field of thin plate grinders, in particular to a rolling structure of thin plate grinders. Background technique [0002] At present, in the process of processing printed circuit boards, the industry generally uses thin plate grinders to remove the entire surface and burrs of printed circuit boards. [0003] Among them, at least two sets of second brushing groups and first brushing groups are arranged between the two side plates of the thin plate grinder, wherein the second brushing group includes the second cylinder and the second back pressure wheel corresponding up and down, The first brush grinding group includes the first back pressure wheel and the first cylinder corresponding up and down, and the outer wall of each cylinder is provided with rolling brushes in the circumferential direction, so that when the printed circuit board passes between each cylinder and the back pressure wheel, it can Scrub with a la...

AI Technical Summary

Problems solved by technology

[0004] Any of the above-mentioned brush grinding groups is a fixed structure, and there is no room for adjustment. When grinding printed circuit boards with different thickness specifications, especially thicker circuit boards, it is necessary to replace rollers with different diameter specifications, or to use rollers with different diameters. Thin plate grinders with different drum specifications are not only inconvenient to replace and use, but also increase material and labor costs
