Raw material elevator for aluminum bar machining

A placing mechanism comprises a bottom plate, side plates are fixedly connected to the two sides of the top of the bottom plate, a through groove is formed in one side of each side plate in a penetrating mode, the top of a groove cavity of each through groove is provided with an opening, a fixing plate is fixedly connected between the two side plates, and the top of the fixing plate is provided with an opening. The bottom of the fixing plate is fixedly connected with an air cylinder, the output end of the air cylinder is fixedly connected with a baffle, a clamping groove is formed in one side of the side plate, and the interior of the clamping groove is matched with the outer surface of the baffle. According to the raw material elevator for aluminum bar machining, under the cooperative use of the bottom plate, the side plates, the through grooves, the fixing plates, the air cylinders, baffles and clamping grooves, the problems that after an existing raw material elevator is lifted to a certain height, the sid
