[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a paint sand grinder capable of fully grinding, comprising a base plate 1, a body 2 is mounted on the top of the base plate 1, a grinding roller 3 is mounted on one side of the body 2, two support plates 4 are slidably connected to the top of the base plate 1, a grinding barrel 5 is fixedly connected to the inner side of the support plate 4, two through slots 6 are provided on one side of the grinding barrel 5, a driving rod 7 is slidably connected inside the through slot 6, a circular scraper 8 is fixedly connected to one side of the driving rod 7, a handle 9 is fixedly connected to the bottom of the driving rod 7, and two hollow blocks 10 are fixedly connected to one side of the grinding barrel 5;

[0024] A fixing mechanism for fixing the circular scraper 8 is installed inside the hollow block 10. The staff moves the two driving rods 7 to drive the circular scraper 8 to move inside the grinding barrel 5, and cooperates with the fixing mechanism to thoroughly scrape off the material remaining on the inner wall of the grinding barrel 5, preventing uneven grinding or blockage caused by the accumulation of material on the barrel wall.

[0025] Reference Figure 1 、 Figure 4 and Figure 5As shown, in this embodiment: the fixing mechanism includes a cover plate 11 installed inside the hollow block 10, and a first through-groove 12 is provided on one side of the cover plate 11, and a moving rod 13 is slidably connected inside the first through-groove 12, and an arc-shaped pushing block 14 is fixedly connected to one side of the moving rod 13, and a second through-groove 15 is provided at the bottom of the inner cavity of the hollow block 10, and a plug-in rod 16 is slidably connected inside the second through-groove 15, and an arc-shaped force-bearing block 23 is fixedly connected to the top of the plug-in rod 16, and a plug-in groove 17 is provided at the bottom of the inner cavity of the hollow block 10. When the staff adjusts the moving rod 13, the arc-shaped pushing block 14 of the moving rod 13 pushes the arc-shaped force-bearing block 23, so that the arc-shaped force-bearing block 23 drives the plug-in rod 16 to move downward, and passes through the second through-groove 15 and is inserted into the plug-in groove 17 at the top of the driving rod 7, so as to prevent the circular scraper 8 from shaking when the machine is in use.

[0026] Reference Figure 5 As shown, in this embodiment: limiting grooves 18 are provided at both ends of the inner cavity of the hollow block 10, and both ends of the arc-shaped force-bearing block 23 are fixedly connected to limiting blocks 19. The coordinated use of the limiting grooves 18 and the limiting blocks 19 can ensure the precise positioning of the arc-shaped force-bearing block 23 in the inner cavity of the hollow block 10, so that the arc-shaped force-bearing block 23 is not easily offset or shaken when subjected to external force.

[0027] Reference Figure 5 As shown, in this embodiment: the bottom of the arc-shaped force-bearing block 23 is fixedly connected with a reset spring 20, and the bottom of the reset spring 20 is fixedly connected to the bottom of the inner cavity of the hollow block 10. The setting of the reset spring 20 enables the arc-shaped force-bearing block 23 to quickly rebound and reset after being subjected to pressure, ensuring that the arc-shaped force-bearing block 23 can continuously and effectively bear and transmit force.

[0028] Reference Figure 5 As shown, in this embodiment: one end of the arc-shaped pushing block 14 is fixedly connected to a thrust spring 21, and one end of the thrust spring 21 is fixedly connected to one end of the cover plate 11. Through the setting of the thrust spring 21, when the arc-shaped pushing block 14 and the arc-shaped force-bearing block 23 are in abutment state, the thrust spring 21 will transmit its own force to one end of the arc-shaped pushing block 14, making it more stable when fixed.

[0029] Reference Figure 5 As shown, in this embodiment: the surface of the plug rod 16 is slidably connected to the inside of the plug groove 17, and the external shape of the plug rod 16 is consistent with the internal shape of the plug groove 17, ensuring that the plug rod 16 can be stably and firmly inserted into the plug groove 17, thereby improving the stability and reliability of the overall structure. Regardless of whether it is a static load or a dynamic load, the plug rod 16 can maintain its position in the plug groove 17 stably.

[0030] Reference Figure 3As shown, in this embodiment: a sealing gasket 22 is fixedly connected to one side of the circular scraper 8, and one side of the sealing gasket 22 abuts against the interior of the grinding barrel 5. The setting of the sealing gasket 22 effectively enhances the sealing between the circular scraper 8 and the inner wall of the grinding barrel 5, prevents the material from leaking from the gap during the grinding process, and ensures the smooth progress of the grinding process.

[0031] Working principle: The staff drives the circular scraper 8 to move inside the grinding barrel 5 by moving the two driving rods 7, and cooperates with the fixing mechanism to thoroughly scrape off the residual materials on the inner wall of the grinding barrel 5, preventing uneven grinding or clogging caused by the accumulation of materials on the barrel wall. When the staff adjusts the moving rod 13, the arc-shaped pushing block 14 of the moving rod 13 pushes the arc-shaped force block 23, so that the arc-shaped force block 23 drives the plug-in rod 16 to move downward, and passes through the second through-groove 15 and is inserted into the plug-in groove 17 at the top of the driving rod 7, so as to avoid the circular scraper 8 from shaking when the machine is in use. The cooperation of the limiting groove 18 and the limiting block 19 can ensure the precise positioning of the arc-shaped force block 23 in the inner cavity of the hollow block 10, so that the arc-shaped force block 23 is not easy to deviate or shake when subjected to external force, and reset The setting of the spring 20 enables the arc-shaped force-bearing block 23 to rebound and reset quickly after being subjected to pressure, ensuring that the arc-shaped force-bearing block 23 can continuously and effectively bear and transmit force. Through the setting of the thrust spring 21, when the arc-shaped pushing block 14 and the arc-shaped force-bearing block 23 are in abutment, the thrust spring 21 will transmit its own force to one end of the arc-shaped pushing block 14, making it more stable when fixed, ensuring that the plug-in rod 16 can be stably and firmly inserted into the plug-in groove 17, thereby improving the stability and reliability of the overall structure. Regardless of static load or dynamic load, the plug-in rod 16 can maintain its position stable in the plug-in groove 17. The setting of the sealing gasket 22 effectively enhances the sealing between the circular scraper 8 and the inner wall of the grinding barrel 5, preventing material from leaking from the gap during grinding, and ensuring the smooth progress of the grinding process.
