Abstract
Description
Technical Field

[0002] Wooden packaging boxes are a common type of transport and storage container, widely used in industries such as industry, agriculture, and logistics. The surface polishing process of wooden box boards is an important step in improving the appearance quality and performance of wooden boxes. The motor drives the sanding belt or sanding disc and other abrasive tools to rotate at high speed, contacting and rubbing with the surface of the board, thereby removing burrs, uneven parts, and excess wood chips on the surface of the board, making the surface gradually smooth.
[0003] When using the existing packaging box plate surface polishing equipment, it is not easy to control the contact pressure between the grinding roller and the side of the plate due to the narrow side of the plate, and the position of the grinding roller is fixed, which will cause serious local wear of the grinding roller and reduce the service life of the grinding roller. In addition, when grinding plates of different thicknesses, positioning adjustment is required according to the thickness of the plate. The operation process is relatively cumbersome, and frequent shutdowns are required to adjust the height of the grinding roller, which will consume a long working time and greatly reduce production efficiency.
