Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically a sandblasting equipment that allows for the recycling of waste sand. Background Technology

[0002] Sandblasting machines fall under the category of air conveying machinery. They utilize compressed air to transport powdery particles (1-4mm in diameter) from one location to another within a pipeline. During this process, kinetic energy is converted into potential energy, causing the high-speed moving sand particles to scour the surface of an object, thereby improving its surface quality. Among them, the pressure-driven dry sandblasting machine uses compressed air as its power source. The working pressure established by the compressed air in the pressure tank forces the abrasive through the sand outlet valve into the sand delivery pipe and out through the nozzle, spraying it onto the surface to be processed to achieve the desired processing purpose. In the pressure-driven dry sandblasting machine, compressed air serves as both the power source for material supply and the acceleration power source for the jet.

[0003] According to a sandblasting machine with a waste sand recycling structure (Announcement No.: CN218254637U), the aforementioned application allows grinding debris in the sand particles to be filtered and collected below the second guide screen plate. The filtered waste sand particles are guided through the second guide screen plate to the discharge port and discharged into the waste sand collection box for collection. This facilitates the user to recycle and reuse the waste sand collected in the waste sand collection box, reducing sand waste and lowering the user's processing costs.

[0004] However, in actual use, the sandblasting machine usually sprays a large amount of sand particles onto the surface of the object when it performs sandblasting and grinding. If the sand particles are not recycled, it will result in a large waste of sand particles and increase the operating cost of the equipment. In view of this, we propose a sandblasting equipment that can recycle waste sand. Utility Model Content

[0026] In one embodiment of this utility model, a sandblasting gun is provided at the bottom end of the sandblasting pipe 7 to facilitate sandblasting of objects on the fixed base 6. A motor 301 is fixedly installed on the inner wall of the machine body 1, and a cam 302 is fixedly connected to the output end of the motor 301. A fixing plate 303 is fixedly installed on the inner wall of the machine body 1. A support rod 304 is fixedly connected to the upper surface of the fixing plate 303, and a return spring 305 is fixedly connected to the upper surface of the support rod 304. A movable filter plate 306 is slidably connected to the inner wall of the machine body 1. A connecting rod 310 is fixedly installed on the lower surface of the movable filter plate 306, and a roller 309 is rotatably connected to the lower surface of the connecting rod 310. A through hole 308 is opened on the surface of the movable filter plate 306.

[0027] In addition, the promoting mechanism 4 includes a push rod 401, which is rotatably mounted on the upper surface of the fixed plate 303. A rotating protrusion 402 is fixedly mounted on the arc surface of the push rod 401. A rotating groove is provided inside the through hole 308. The diameter of the rotating protrusion 402 is matched with the diameter of the rotating groove to facilitate the rotation of the push rod 401.

[0028] In this embodiment of the invention, two support rods 304 are provided, and the ends of the two support rods 304 are fixedly connected by a return spring 304. Two support rods 304 form a group, and three groups of support rods 304 form a row. A row of support rods 304 is fixedly installed on the upper surface of the fixing plate 303 in a circumferential array. The end of the top rod 401 near the through hole 308 is beveled. The support rods 304 and the through hole 308 are connected. Correspondingly, the number of rotating protrusions 402 is set to two, and the two rotating protrusions 402 are mirror images of the left and right arc surfaces of the top rod 401.
