ABSTRACT:
A belt sander includes a base, a sanding device, a worktable, a tipping drive device, and a swinging device. The swinging device includes a cylindrical roller, a central shaft, a toothed ring, a drive gear, a cam, and a fixing rod. The swinging device drives the sanding device to produce a slightly reciprocally swinging action during operation of the sanding device. Thus, the grinding path and area of the sand belt are increased largely by the reciprocally and successively swinging action of the swinging device and the sanding device, so that the sand belt can be used to grind the wooden material exactly and efficiently, thereby greatly enhancing the grinding and finishing effect of the belt sander.
