Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a sandblasting machine with a sand collecting structure. Background Art

[0002] Sandblasting machine belongs to the category of air conveying machinery. It uses compressed air in a pipeline to transport powdered granular materials from one place to another. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object, so that the surface of the workpiece obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved. Therefore, the fatigue resistance of the workpiece is improved, the adhesion between it and the coating is increased, the durability of the coating is extended, and it is also beneficial to the leveling and decoration of the coating, and the impurities, colors and oxide layers on the surface are removed. At the same time, the surface of the medium is coarsened, the residual stress of the workpiece is eliminated, and the surface hardness of the substrate is improved.

[0003] A Chinese patent with application number CN219725835U discloses a sandblasting machine with a sand collecting structure, which relates to the technical field of sandblasting equipment. The sandblasting machine with a sand collecting structure comprises a sandblasting machine, wherein a conveyor belt is arranged inside the sandblasting machine, through holes are provided on the surface of the conveyor belt, and the through holes are evenly distributed on the surface of the conveyor belt. A motor is fixedly connected to the top of the sandblasting machine, and a rotating block is fixedly connected to the output end of the motor. A rotating shaft is rotatably sleeved inside the rotating block. A card slot is provided inside the sandblasting machine, and a sliding device is provided inside the card slot. In the sandblasting machine with a sand collecting structure, large-particle workpiece waste gradually slides downward on the upper surface of the filter screen and falls into the inside of the left and right collecting slots. The large-particle workpiece waste is collected separately by the two collecting slots, which is convenient for the staff to centrally process the waste, prevent the workpiece waste from being mixed with the sandblasting abrasive, and improve the processing effect of the sandblasting abrasive on the workpiece surface.

[0004] Although the above technology can move the screen left and right to screen the waste chips and sandblasting materials, the screen is easily stuck between the screen and the inside of the sandblasting machine by large particles of workpiece waste chips during the left and right movement of the screen. At the same time, it is easy for scattered waste chips and sandblasting materials to get stuck on the slide bar, affecting its movement and increasing the frequency of shutdown for maintenance. Therefore, a sandblasting machine with a sand collection structure is proposed based on this technology. Utility Model Content
