Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, and in particular to sandblasting machines. Background Technology

[0002] Sandblasting machines are widely used for surface treatment of metals, non-metals, wood, and plastics. They are an indispensable and important process in modern industrial production, playing a vital role in many fields such as automobile manufacturing, shipbuilding, metal processing, construction, and aerospace. For example, in automobile manufacturing, they are used to remove rust, paint, coatings, and other contaminants from car bodies and parts before painting, welding, or further processing to ensure the quality and lifespan of the final product. With the popularization of IoT and big data technologies, sandblasting machines are beginning to develop towards intelligence, automatically adjusting sandblasting parameters according to the workpiece material and surface condition, thus improving sandblasting efficiency and workpiece quality.

[0003] A search revealed Chinese Patent Publication No. CN222874261U, which discloses a fully automatic sandblasting machine. The machine includes a protective housing with a sand-collecting hopper on its lower surface and a support bracket fixedly mounted on its upper surface. A sandblasting device is rotatably engaged with the center of the inner end face of the support bracket. A servo motor is positioned on the upper end face of the support bracket near the sandblasting device, and a drive synchronous pulley is fixedly mounted at the output end of the servo motor. This invention, during sandblasting... The feeding slide plate can work in conjunction with the protective box for enclosed feeding, so that when the sandblasting drum is circling the workpiece for sandblasting, the protective box is a closed structure, which can effectively improve the stability of sandblasting. In addition, the feeding slide plate has multiple sets of workpieces inside, and can work in conjunction with the protective box for cyclic feeding, which can effectively improve the efficiency of the equipment in sandblasting the workpieces inside the feeding slide plate. However, this utility model does not take into account that there will still be residual sand on the surface of the object after sandblasting. If the residual sand cannot be screened and recycled in multiple stages, it will lead to sand waste, increase the cost of sandblasting, and reduce the efficiency of sandblasting. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sandblasting machine, which aims to improve the problem that residual sand remains on the surface of objects after sandblasting in the prior art. If the residual sand cannot be screened and recycled in multiple stages, it will lead to sand waste, increase the cost of sandblasting, and reduce the efficiency of sandblasting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sandblasting machine, including a housing, a connecting plate fixedly connected to the left side of the housing, a processing machine fixedly connected to the left side of the connecting plate, a recycling mechanism provided at the bottom of the connecting plate, the recycling mechanism being used for multi-stage screening and recycling of sand, and a discharge component provided at the bottom of the recycling mechanism, the discharge component being used for discharging the recycled sand. The recycling mechanism includes a collection box, the right side of which is fixedly connected to the bottom left side of the casing. A coarse screening component is provided on the top of the inner wall of the collection box, and a fine screening component is provided on the bottom of the inner wall of the collection box. A rotating shaft is provided on the top of the connecting plate, and a transmission roller is fixedly connected to the outer wall of the rotating shaft. Fixing components are provided on both the front and rear sides of the outer wall of the rotating shaft.

[0006] Through the above technical solution: the processing machine is responsible for the fine processing of materials. The recycling mechanism can perform multi-stage screening and recycling of sand particles, ensuring that each grain of sand is fully utilized, and the discharge component can orderly discharge the recycled sand particles, preparing them for the next round of processing; The collection box is tightly connected to the casing, which not only provides stable support for the entire recycling mechanism, but also ensures that the sand particles can enter smoothly during the screening process. The coarse screening component will screen out larger sand particles, while the fine screening component at the bottom of the inner wall can screen the remaining sand particles more finely.

A coarse discharge assembly is provided at the top front side of the collection box, and a fine discharge assembly is provided at the bottom front side of the collection box.

[0008] Through the above technical solution: the support plate is not only firmly connected to the bottom left and right sides of the collection box, but its top is also tightly connected to the bottom of the collection box, ensuring the overall stability of the discharge component. The cavity reduces the weight of the component.

The outer walls of the two fixed plates are fixedly connected to the middle left and right sides of the inner wall of the collection box. Spring columns are fixedly connected to the top front and rear sides of the fixed plates, and a screen is provided on the top of the spring columns.

[0010] The above technical solution ensures a stable connection between the fixed plate and the inner wall of the collection box on both sides, provides the necessary elasticity during the screening process to adapt to the screening requirements of different materials, and ensures that the screen size can effectively separate materials of the required particle size while maintaining high processing efficiency.

[0011] As a further description of the above technical solution: The fine screening component includes two fixed plates. The outer walls of the two fixed plates are fixedly connected to the bottom front and rear sides of the inner wall of the collection box.

[0014] The above technical solution ensures that the rotating column can be flexibly adjusted to adapt to different material discharge requirements. The rotating plate not only enhances the stability of the rotating column, but also enables precise control of material flow through the locking block fixedly connected to its front bottom. The locking block allows the operator to easily adjust the rate and amount of material discharge according to actual needs, thereby achieving efficient and precise material processing results.

[0015] As a further description of the above technical solution: The coarse discharge assembly includes a sliding plate, the rear side of which is slidably connected to the front side of the collection box, a fixing block is fixedly connected to the top front side of the sliding plate, and a groove is provided on the top front side of the collection box.

[0019] As a further description of the above technical solution: The outer wall of the sliding plate is slidably connected to the inner wall of the sliding groove, and the outer wall of the support plate is fixedly connected to the right side of the processing machine.

[0020] The above technical solution not only enhances the stability of the entire production line, but also ensures the accuracy and safety of the processing machine when it is running at high speed. The support plate provides a solid foundation for the entire processing process, enabling the material to be smoothly transferred from the processing machine to the coarse discharge component, and then efficiently carried out subsequent processing.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the sandblasted decorative panel moves to the left via a rotating shaft and a transmission roller. Excess sand falls into a collection box. The sand is first screened by a screen to remove large particles, and the vibration of the screen prevents sand accumulation. The screened sand falls onto a screen plate for secondary screening. Spring plates help prevent sand accumulation, realizing multi-stage screening and recycling of sand. This allows the sand to separate particles of different sizes, facilitating subsequent use and reducing sandblasting costs.

[0022] 2. In this utility model, large sand particles are trapped by the screen and can be removed for collection. The sand on the screen plate is discharged by pushing the fixed block to make the sliding plate slide out. The sand powder layer is discharged by pulling the card block to make the rotating plate rotate around the rotating column. This realizes the discharge of sand of different particle sizes and prevents the accumulation of sand of the same particle size due to long-term use, which affects the filtration effect.

[0030] Working principle: After the decorative panel is sandblasted, it is driven to the left by the rotating shaft 201 and the transmission roller 202. The excess sand on the decorative panel will fall into the collection box 203 through the gap between the transmission rollers 202. The sand will first be screened by the screen 2043. The screen 2043 can screen out larger sand particles. When the sand collides with the screen 2043, it will exert an impact force on the screen 2043, causing the screen 2043 to squeeze the spring column 2042 and then bounce back. The repeated back and forth movement of the screen 2043 can prevent the sand from accumulating. After passing through the first layer of screening, it will fall onto the screen plate 2053. The screen plate 2053 can screen the sand again. At the same time, the spring plate 2052 can also play a role in preventing accumulation. This realizes multi-stage screening and recycling of sand, which can separate sand particles of different sizes, thereby facilitating subsequent use and reducing sandblasting costs. Larger sand particles will be blocked at the top by the screen 2043, and can be collected by removing the screen 2043 from the inside of the collection box 203. The sand on the screen plate 2053 can be discharged by pushing the fixed block 3033 upward, causing the sliding plate 3031 to slide upward along the chute 3032. The last layer of sand can be discharged by pulling the locking block 3043, causing the rotating plate 3042 to rotate around the outer wall of the rotating column 3041. This allows for the discharge of sand of different particle sizes, preventing the accumulation of the same type of sand over a long period of use, which would affect the filtration effect.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
