Description

Technical Field

[0001] The invention relates to the technical field of edge grinding equipment, in particular to an automatic compensation device for grinding wheel wear of an edge grinding machine. Background Art

[0002] With the rapid development of technology in the field of deep processing of ceramic tiles, edge grinding machines play an indispensable role in the deep processing of ceramic tiles. In the process of ceramic tile production, since the periphery of the formed bricks is not flat enough, it is usually necessary to use edge grinding machines to fine-process the periphery of the formed bricks, so that the periphery of the formed bricks is uniform in size and the surface is smooth and flat.

[0003] When the edge grinding machine is edge grinding the ceramic tile, the conveying mechanism conveys the ceramic tile, and the driving motor drives the grinding wheel to rotate and grind the ceramic tile in the conveying process. As the working time increases, the working surface of the grinding wheel will inevitably wear out. When adjusting the grinding wheel feed amount, if the grinding wheel wear is not compensated, the grinding wheel position will not be adjusted properly, resulting in deviations in the processing size of the ceramic tile. At present, there is a method of detecting the wear of the grinding wheel by a non-contact sensor for compensation. The sensor is fixedly installed relative to the wear position. The position of the working surface of the grinding wheel is detected by a non-contact sensor such as infrared or visual, and compared with the initial data to determine the wear of the grinding wheel, and compensate and adjust the grinding wheel position according to the wear. However, when the grinding wheel is processing ceramic tiles, especially dry edge grinding, it will generate a lot of dust, which is easy to cover the detection end of the non-contact sensor such as infrared or visual, resulting in deviations in the wear detection data, affecting the adjustment of the grinding wheel compensation amount.

When the working time increases and the working surface of the grinding wheel 25 is worn, a plurality of compression springs 266 are pressed against the transmission arm 263, and the plurality of positioning balls 2611 are pressed against the transmission arm 263, so that the installation back plate 2610 and a plurality of positioning balls 2611 always have a tendency to move closer to the grinding wheel 25 for work. When the working time increases and the working surface of the grinding wheel 25 is worn, a plurality of compression springs 266 are pressed against the transmission arm 263, and the ... The spring 1 266 moves with the working surface of the grinding wheel 25 after wear, driving the transmission arm 263 to move synchronously, and the transmission arm 263 moves toward the side close to the push-pull force sensor 269, so that the compression amount of the compression spring 268 changes, and the pressure exerted on the push-pull force sensor 269 by the compression of the compression spring 268 increases.
