Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a sanding belt tensioning structure for a woodworking sanding machine. Background Art

[0002] The basic principle of a woodworking sander is to achieve the purpose of sanding wood through the rotation and friction of the sanding belt. The abrasive particles (such as sand or abrasive) on the sanding belt come into contact with the surface of the wood, and the unevenness and stains on the surface of the wood are removed through the grinding action to make it smooth.

[0003] The belt tensioning structure of traditional woodworking sanding machines may cause the belt to become loose during sanding. Insufficient belt tension may cause the belt to fall off or rotate abnormally during high-speed operation, increasing the safety risk during the work process. Workers may be injured or equipment may be damaged. In this way, the machine needs to be stopped to adjust the belt, which increases the downtime and reduces production efficiency.

[0004] Therefore, those skilled in the art provide a sanding belt tensioning structure for a woodworking sanding machine to solve the problems raised in the above background technology. Utility Model Content
