[0001] The utility model relates to the technical field of sandblasting machines, in particular to an automatic feeding device for sandblasting machines. Background technology:

[0002] After the aluminum profile is produced and formed, the surface needs to be sandblasted by a sandblasting machine. The sandblasting machine uses powdered materials to scour the surface of the aluminum profile, thereby changing the surface properties of the aluminum profile and improving the quality of the aluminum profile. The existing sandblasting machine is not convenient for recycling the processed powdered materials, and materials need to be continuously added to the sandblasting machine, which increases the processing cost;

[0003] According to China's authorization announcement number CN218082207U, a feeding and discharging mechanism for a sandblasting machine is provided, including a horizontal fixed plate, a transport conveyor belt and a conveying conveyor belt, the upper surface of the horizontal fixed plate is respectively fixedly connected with two lifting hydraulic rods and a flip hydraulic rod, the telescopic ends of the two lifting hydraulic rods are jointly movably hinged with a conveying box, the bottom surface of the conveying box is provided with a sliding groove, the telescopic end of the flip hydraulic rod is movably hinged with a moving block, the moving block is slidably connected to the inside of the sliding groove, the outer surface of the transport conveyor belt and the outer surface of the conveying conveyor belt are respectively fixedly connected with a first The baffle plate and the second baffle plate; the upper surface of the horizontal fixed plate is fixedly connected to two first rotating frames, and the insides of the two first rotating frames are rotatably connected to the outgoing driving shaft and the outgoing driven shaft, and the outer surfaces of the outgoing driving shaft and the outgoing driven shaft are in contact with the inner wall of the outgoing conveyor belt; the left end of the outgoing driving shaft is fixedly connected to the first rotating motor, and the bottom surface of the first rotating motor is fixedly connected to the upper surface of the horizontal fixed plate, and the materials are transported to the conveying box through the outgoing conveyor belt and the conveying conveyor belt, and the lifting hydraulic rod and the flipping hydraulic rod can lift the conveying box to the conveying conveyor belt. In order to make the hydraulic rod flip to dump the material in the conveying box to the conveyor belt, the conveyor belt re-inputs the material for utilization, thereby reducing the processing cost. However, the lifting hydraulic rod and the flip hydraulic rod are connected to the bottom surface of the conveying box, and the distance between the transport conveyor belt and the horizontal fixed plate is small, and the distance between the transport conveyor belt and the conveyor belt is large. In order to make the conveying box flush with the top surface of the transport conveyor belt, the hydraulic rod and the flip hydraulic rod need to be set at a lower height, which limits the retractable length of the telescopic ends of the hydraulic rod and the flip hydraulic rod, thereby causing the hydraulic rod and the flip hydraulic rod to actually be unable to lift the conveying box to the position of the conveyor belt. Therefore, the lifting structure of the conveying box is not set reasonably. In addition, the method of dumping the conveying box by the flip hydraulic rod requires the material to fall from the top of the conveying box to the conveyor belt. However, due to the limitation of the hinged structure of the hydraulic rod and the conveying box, the flip hydraulic rod actually flips the conveying box at a small angle, and the conveying box cannot be flipped to 90°. In this way, there will always be a lot of materials retained in the conveying box, and the materials in the conveying box cannot be dumped onto the conveyor belt, thereby reducing the recycling efficiency of the materials.
