[0002] Abrasive blasting machine is a device that uses abrasive particles to blast the surface of a workpiece. It uses compressed air or compressed gas to spray abrasives onto the surface to be processed to remove dirt, scale, rust, etc. on the surface, thereby improving the quality and roughness of the surface and enhancing its adhesion. The evenly stirred abrasive can ensure that the abrasive is evenly distributed during the blasting process, thereby improving the blasting efficiency and the processing quality of the workpiece surface.

When the abrasive is put into the material box, the stirring motor installed on one side of the mounting frame is controlled to rotate to drive the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the transmission belt. The driven wheel rotates to drive the transmission rod fixed in the middle to rotate, and the surface of the transmission rod A stirring blade is installed to stir the abrasive inside the material box so that the abrasive is evenly stirred. After being sprayed out by the sandblasting mechanism, the surface of the workpiece can maintain a uniform polishing surface. Compared with the comparative document, the sandblasting machine has the function of stirring the abrasive evenly, avoiding the abrasive from being embedded and accumulated in the material box, thereby improving the sandblasting effect.

This setting only stirs the middle part of the abrasive, resulting in uneven stirring of the abrasive and uneven distribution of abrasive particles during the sandblasting process, which will affect the uniformity of the sandblasting effect and make the quality of the workpiece surface treatment inconsistent.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-2, the utility model provides an embodiment: a sandblasting machine for uniformly stirring abrasives, comprising a stirring chamber 1, a top plate 2 is arranged on the top of the stirring chamber 1, a motor 3 is fixedly connected to the upper surface of the top plate 2, a rotating plate 4 is fixedly connected to the output end of the motor 3, the outer wall of the rotating plate 4 is rotatably connected to the inside of the top plate 2, a rotating rod 7 is rotatably connected to the inside of the rotating plate 4, a gear 5 is fixedly connected to the outer wall of the rotating rod 7, an annular rack 6 is fixedly connected to the inside of the top plate 2, the annular rack 6 is meshed with the gear 5, the bottom of the rotating rod 7 is rotatably connected to the bottom of the stirring chamber 1, a plurality of stirring blades 8 are fixedly connected to the middle of the outer wall of the rotating rod 7, a feeding port 10 is fixedly connected to the inside of the stirring chamber 1, a feeding plate 9 is fixedly connected to the bottom of the stirring chamber 1, and a supporting assembly is arranged on the outer wall of the stirring chamber 1;

[0023] Specifically, first, the abrasive needs to be accurately placed inside the mixing chamber 1 through the feed port 10. In this way, the raw materials can be evenly distributed during the mixing process, laying a solid foundation for subsequent mixing operations. Next, turn on the motor 3 above the top plate 2, which is the core driving part of the entire mixing equipment. After starting, the motor 3 will drive the rotating plate 4 to rotate at high speed through its output end. This step is very important because the rotating plate 4 is responsible for transmitting power to the rotating rods 7 on both sides. Driven by the rotating plate 4, the rotating rods 7 on both sides will quickly follow up and rotate synchronously. At this time, the function of the rotating rod 7 is to transmit power to the gear 5 and stirring blade 8, which are the key links of power transmission in the stirring process. When the gear 5 is connected to the rotating rod 7, the gear 5 will rotate around the annular rack 6. It is worth mentioning that there is a meshing connection relationship between the gear 5 and the annular rack 6, which enables the gear 5 to rotate around the annular rack 6 and rotate on its own during the rotation process. Driven by this double rotation, the stirring blade 8 will rotate efficiently inside the stirring chamber 1. At the same time, the stirring blade 8 also rotates around the rotating rod 7. This double rotation method enables the material to be mixed in an all-round and three-dimensional manner during the stirring process, thereby achieving a full stirring effect.

[0024] Reference Figure 1 The supporting assembly includes a fixing frame 11, and the outer wall of the fixing frame 11 is fixedly connected to the outer wall of the mixing chamber 1;

[0025] Specifically, the effect of supporting and fixing the mixing chamber 1 is achieved through the fixing frame 11 in the supporting assembly.

[0026] Reference Figure 3The outer wall of the fixed frame 11 is fixedly connected with a bottom plate 12, the bottom of the unloading plate 9 is fixedly connected to the inside of the bottom plate 12, the inside of the bottom plate 12 is fixedly connected with a cylinder 13, the output end of the cylinder 13 is fixedly connected with a slide plate 14, the outer wall of the slide plate 14 is slidably connected to the bottom plate 12, the inside of the bottom plate 12 is fixedly connected with a unloading pipe 15, the lower surface of the bottom plate 12 is fixedly connected with a fixed block 16, the lower surface of the fixed block 16 is fixedly connected with a motor 2 17, the output end of the motor 2 17 is fixedly connected with an auger blade 18, and the outer wall of the auger blade 18 is rotatably connected to the inner wall of the unloading pipe 15;

[0027] Specifically, the abrasive after stirring is transported to the preset through hole inside the skateboard 14. The design of the through hole is to ensure that the material can flow smoothly from the inside of the skateboard 14 to the lower feeding pipe 15. In order to achieve quantitative feeding, we need to open the cylinder 13 inside the bottom plate 12. The cylinder 13 drives the skateboard 14 to move through the output end to deliver the material inside the skateboard 14 to the inside of the lower feeding pipe 15. In this way, we can accurately control the material delivery amount to meet the needs of the production process. After completing the quantitative feeding, we need to turn on the motor 2 17 under the fixed block 16. The motor 2 17 drives the auger blade 18 to rotate inside the lower feeding pipe 15 through the output end. This design helps to achieve uniform transportation of the abrasive and ensure that the material will not be blocked in the pipeline. At the same time, it improves production efficiency. In summary, through the synergistic effect of the cylinder 13 and the motor 2 17, we have achieved quantitative feeding and uniform transportation of the abrasive after stirring, which not only improves production efficiency, but also helps to ensure the quality of the material.

[0028] Working principle: When a sandblasting machine is needed to mix abrasives evenly, the abrasives are first placed inside the mixing chamber 1 through the feed port 10, and then the motor 3 above the top plate 2 is turned on, and the rotating plate 4 is driven to rotate through the output end of the motor 3, thereby driving the rotating rods 7 on both sides to rotate, and then the rotating rods 7 drive the gear 5 and the stirring blade 8 to rotate. Since the gear 5 and the annular rack 6 are in a meshing connection relationship, the gear 5 rotates around the annular rack 6 while rotating on its own, thereby driving the stirring blade 8 to rotate inside the mixing chamber 1. The abrasive material after stirring is sent to the preset through hole in the slide plate 14 through the discharge plate 9, and then the cylinder 13 in the bottom plate 12 is turned on, and the slide plate 14 is driven to move through the output end of the cylinder 13, so that the material in the slide plate 14 is sent to the inside of the discharge pipe 15, so as to achieve the effect of quantitative feeding, and then the motor 17 under the fixed block 16 is turned on, and the auger blade 18 is driven to rotate in the discharge pipe 15 through the output end of the motor 17, so as to achieve the effect of uniformly conveying the abrasive material.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
