Abstract
The invention discloses a sanding mechanism of a sanding machine and particularly relates to a sanding mechanism of a sanding machine with an obliquely arranged sand frame. The sanding mechanism comprises a conveying belt and sand frames arranged above the conveying belt; grinding heads which lean against the conveying belt are arranged at the lower ends of the sand frames; at least two sanding frames are arranged; an angle difference is arranged between each two sanding frames; and an angle difference is reserved between the tangential direction of at least one sanding frame in a contact region and a vertical feeding direction. With the adoption of the structure, the grinding superficial area is effectively enlarged and scratching phenomena are reduced; and surface microcosmic burrs are reduced so that the surface quality is improved, the sudden change of an instantaneous load is greatly reduced, the fixed thickness machining precision is greatly improved and the machine faults are reduced. When the sanding frames are symmetrically and obliquely arranged, the axial force generated by obliquely arranging and grinding can be mutually cancelled out so as to prevent fed materials of the machine from running or a work piece from deviating and prevent head knocking and tail blowing phenomena generated by the reason that the work piece warps when front and rear edges of the work piece enter a grinding region and leave from the grinding region.
