[0002] The shot blasting machine is a device that is composed of an impeller body, a shot blasting wheel, a shot dividing wheel, an electric motor and other components and is capable of projecting projectiles.

[0003] When the shot blasting machine is working, after the projectile flows into the shot blasting machine from the shot inlet pipe, the shot dividing wheel that rotates synchronously with the blade makes the projectile obtain an initial velocity, and is thrown onto the high-speed rotating blade outside the directional sleeve, and then projected onto the surface of the workpiece to be cleaned, so as to achieve the effect of cleaning the surface of the workpiece. In the operation of the existing device, the cleaning efficiency of the shot blasting is generally improved by controlling the flow rate of the projectile, but the existing method of controlling the flow rate is generally manual adjustment or using a power device to adjust the shot inlet over a large range, and it is impossible to adjust multiple lines inside the shot inlet channel to achieve the effect of adjusting the flow rate, which affects the diversity of the projectile flow rate adjustment inside the device.

The cam 12 is a block 12 made of stainless steel and is used for making a plurality of connecting tubes 5. ...

[0028] like Figure 1-Figure 5 As shown, a limiting plate 13 is fixedly connected to the outer side of the rotating column 8, and there are at least three limiting plates 13. The limiting plates 13 are located between the two rotating rings 11. The supporting effect of the limiting plates 13 arranged between the two rotating rings 11 and the limiting effect of the supporting plate 4 and the upper end of the rotating column 8 make the positions of the multiple rotating rings 11 stable and accurate when they rotate, thereby improving the accuracy and continuity of the multiple rotating rings 11 when they rotate simultaneously and when they reach the position to stop.

[0029] like Figure 1-Figure 5As shown, a conical guide cylinder 3 is fixedly connected to the inside of the shot inlet pipe 2, and the conical guide cylinder 3 is located above the support disk 4. A guide tube 15 is fixedly arranged inside the shot inlet pipe 2, and the guide tube 15 is located below the support disk 4. A device body 1 is fixedly connected to one side of the shot inlet pipe 2, and the guide tube 15 is fixedly connected to the device body 1. Under the support of the device body 1, materials are poured into the shot inlet pipe 2, so that they flow toward the support disk 4 under the guiding action of the conical guide cylinder 3, and flow to the flow components inside the guide tube 15 under the circulation action of the internal components of the support disk 4, and finally flow to the inside of the device body 1 to operate, forming a coherent and stable circulation route. By setting the conical guide cylinder 3 to a conical structure, it can provide a guiding effect when the material is circulating, ensuring that it can accurately flow to the support disk 4 and the circulation route inside the guide tube 15.

[0030] Example 2

[0031] A flow regulating device for a shot blasting machine, such as Figure 1-Figure 5 As shown, a rotating motor 14 is fixedly connected to one side of the guide tube 15, and the rotating motor 14 is fixedly connected to the rotating column 8. By rotating the rotating motor 14 to different degrees, the rotation of the rotating column 8 can be adjusted, so that its external components can rotate in different ranges to achieve the effect of separate operation.

A supporting ring 6 is fixedly connected to the upper end of the connecting tube 5, and there are at least three supporting rings 6. The supporting ring 6 is used to support the closing plate 12. When the closing plate 12 rotates, by setting the height of the first limiting rod 7 to be slightly lower than the height of the lowest closing plate 12, the position of the lowest closing plate 12 will be limited under the limit of the first limiting rod 7, but it will not affect the continued rotation of the multiple closing plates 12 above. As the closing plate 12 continues to rotate, the multiple limiting rods 7 will limit the closing plate 12 in turn, and at the same time, the multiple supporting rings 6 are set to specifications according to the different heights of the multiple closing plates 12 and the connecting tube 5, so as to support the closed plate 12 after being limited, so that the closing plate 12 can be accurately moved to the position under the dual limit of the outer limiting rod 7 and the internal rotating component, thereby ensuring the accuracy of the position when the connecting tube 5 is closed.

[0033] Working principle: By rotating the rotating column 8, the outer rotating teeth 9 are driven to rotate, so that the outer rotating ring 11 is passively rotated under the meshing of the rotating teeth 9 and the connecting teeth 10, so that multiple closing plates 12 are rotated at the same time, and the rotation range of the rotating column 8 is controlled to make multiple closing plates 12 stop above the connecting cylinder 5 in turn, so as to achieve the effect of closing the connecting cylinder 5, thereby achieving the effect of closing the pill outlet 16 by closing multiple connecting cylinders 5 in different numbers, and being able to limit the number of circulation channels for materials flowing into the pill inlet tube 2, and to adjust the flow rate of the device. By rotating the rotating column 8 The four circles of rotating teeth 9 on the outside are set to be inconsistent in number, increasing from bottom to top. The four circles of connecting teeth 10 inside the rotating ring 11 are adapted to the number of rotating teeth 9, which can achieve different degrees of rotation when multiple closing plates 12 are rotated at the same time, so that the position of the closing plate 12 can be adjusted according to the position of the connecting cylinder 5, so as to achieve the effect of closing multiple connecting cylinders 5 separately or simultaneously, so that the circulating material can obtain different speeds through the connecting cylinders 5 at different angles to enter the pill outlet 16, so that the flow rhythm of the device can be adjusted in time, and the diversity of material flow when the device is in use can be improved.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
