A new flatness detection device for marble production

Abstract

The present application relates to the field of laser measuring instrument, especially to a new flatness detection device for marble production, which comprises a machine body and a slot opened on the machine body; a conveying unit arranged on the machine body, which is lifted when conveying the marble and is lowered after the marble is conveyed to the position to be detected; a following sealing unit arranged in the slot; the following sealing unit is used to control the opening and closing of the slot; through the linkage of the following sealing unit and the conveying unit, the slot is automatically opened in the conveying stage to support the plate by the conveying roller, and the slot is automatically closed in the detection stage to form a seamless supporting surface between the plate and the surface of the machine body; thus, the gap between the back of the plate and the machine body is completely eliminated from the physical level, the multiple secondary reflection paths caused by the laser penetrating the plate and the surface of the conveying roller or the machine body are effectively blocked, and it is ensured that the laser measuring instrument only captures the pure surface reflection signal; thus, the precision and reliability of the flatness detection are significantly improved.
