Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sanding machine, specifically relates to a sanding machine for site old board refrigeration pressure fixed length plate. BACKGROUND

[0002] On the construction site, the sanding treatment of old board refrigeration pressure fixed length plate is a common work, and the sanding machine is a mechanical equipment for sanding or polishing the surface of the plate, which removes the unevenness, wear, scratch, concave-convex and other defects on the surface of the plate through the rotating sandpaper or abrasive tool, so that the smooth and uniform surface is obtained.

[0003] When polishing the plate, the worker first puts the plate into the sanding machine, and another worker goes to the discharge port to wait. When the wood enters the sanding machine for polishing, the grinding wheel contacts and rubs the plate for polishing, and some chippings polished off will fall on the sand belt. The sand belt is not a smooth conveyor belt, and there are gaps on the sand belt. During the sanding process, the friction between the sand belt and the surface of the workpiece will generate a large amount of heat, and the gaps on the sand belt can help dissipate heat and prevent the sand belt from overheating, thereby reducing the wear of the sand belt. However, since there are gaps on the sand belt, the dust and chippings polished off will block the gaps, reducing the friction performance of the sand belt.
