Description

Technical Field

[0001] The utility model relates to the technical field of sanding machines, in particular to a wide-band sanding machine capable of performing double-sided sanding. Background Art

[0002] A sanding machine is a method of physically removing uneven, unevenly thick materials and objects that do not meet process requirements through abrasive cloth, grinding wheels, sandpaper, scouring pads, non-woven polishing wheels, etc., to make them smoother, flatter, and of uniform thickness, so that they meet process standards. It is used in various veneer production processes, standard structural parts production, toy and handicraft industries, decoration and furniture industries, floor and wall panel building materials industries, etc.

[0003] The Chinese patent with the announcement number CN208729436U discloses a wide-band sanding machine, including a machine body, a conveyor belt is arranged on the machine body, and the two ends of the conveyor belt along the length direction thereof are arranged as a feed port and a discharge port, a first active roller and a first driven roller are arranged in the machine body near the feed port, and coarse sandpaper is wound around the first active roller and the first driven roller, a second active roller and a second driven roller are arranged in the machine body near the discharge port, and fine sandpaper is wound around the second active roller and the second driven roller, a connecting frame is arranged inside the machine body, a cylinder for controlling the movement of the first driven roller is arranged on the connecting frame, and a tensioning roller is arranged between the second active roller and the second driven roller on the connecting frame.
