Receiving table of upright saw

A material receiving table of a vertical saw comprises a rack, a roller table, a locking structure, a reset structure and a supporting table, the supporting table is fixed to the rack in the mode that the supporting table can rotate or move relative to the rack so that the supporting table can have different heights relative to the roller table, and the supporting table at least has a first height and a second height; the reset structure can drive the supporting table to ascend from the second height to the first height, the roller table is provided with a plurality of rollers, and at least part of the rollers are located at different heights so that objects on the roller table can automatically move from the first side with the higher rollers to the second side with the lower rollers under the action of gravity. The material receiving action supporting table rolls to the lower side under the action of the idler wheels by means of gravity, the whole process mainly achieves movement by means of the action of g
