[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-4 As shown, this utility model is a grinding machine for casting coating production, including a cylinder 1, with a discharge port 2 on the outer wall of the lower end of the cylinder 1 to facilitate the discharge of the ground raw material. A support column 3 is fixedly connected to the lower end of the cylinder 1, supporting the cylinder 1, and the support column 3 is circumferentially distributed. A shell 4 is provided at the upper end of the cylinder 1, with the lower end of the shell 4 located inside the cylinder 1 to facilitate the smooth entry of raw material into the cylinder 1 during processing and to simultaneously accelerate the grinding efficiency of the raw material. It also includes: the lower end of the inner wall of the cylinder 1 is inclined, which facilitates the smooth discharge of the ground raw material from the discharge port 2. A rotating shaft 5 is provided inside the shell 4, and grinding blocks 12 are provided on the outer wall of the rotating shaft 5. The grinding blocks 12 have evenly distributed protrusions on their outer walls to grind the raw material into small pieces. A groove 7 is provided at the bottom of the shell 4. When the raw material piece to be ground is smaller than the size of the groove 7, the raw material piece will enter the cylinder 1 through the groove 7 for further processing.

[0026] An adjustment mechanism, located inside the rotating shaft 5, is used to adjust the position of the grinding block 12. The adjustment mechanism includes a slide groove 8, a slider 9, a connecting rod 10, a spring 11, a sleeve 13, a baffle 14, and a lead screw 24. The slide groove 8 is located inside the rotating shaft 5, and its dimensions are larger than those of the slider 9, allowing the slider 9 to slide smoothly within the slide groove 8. The slider 9 is slidably connected inside the slide groove 8, and its dimensions decrease from left to right, facilitating the smooth adjustment of the grinding block 12 position by the connecting rod 10. The connecting rod 10 passes through the rotating shaft 5 and is located inside the slide groove 8, with one end of the connecting rod 10 fixedly connected to the grinding block 12. The spring 11 is located on the outer wall of the connecting rod 10, allowing the grinding block 12 to be adjusted. The raw materials are in close contact. The sleeve 13 is set on the outer wall of the connecting rod 10, and the baffle 14 is fixedly connected to the outer wall of the rotating shaft 5. The sleeve 13 and the baffle 14 can prevent raw material particles from entering the connection between the connecting rod 10 and the rotating shaft 5, so that the grinding block 12 cannot be adjusted and the grinding efficiency is affected. The lead screw 24 is fixedly connected to one end of the slider 9 and passes through one end of the rotating shaft 5 and is threaded inside the rotating shaft 5. By rotating the lead screw 24, the slider 9 can move in the slide groove 8. Rotating the lead screw 24 makes the slider 9 slide inside the slide groove 8. When the slider 9 moves to the side end of the slide groove 8, the spring 11 is in a relaxed state, which causes the connecting rod 10 to drive the grinding block 12 to move upward, thereby making the grinding block 12 in close contact with the raw materials.

[0027] The grinding mechanism is located inside the cylinder 1 and is used to grind raw materials. The grinding mechanism includes an inner grinding seat 15 and an outer grinding seat 16. The inner grinding seat 15 is located at the lower end of the cylinder 1 and is truncated cone-shaped with grinding columns evenly distributed on its surface. The outer grinding seat 16 is fixedly connected to the lower end of the inner wall of the cylinder 1, and the inner grinding seat 15 is rotatably connected to the side wall at the lower end of the outer grinding seat 16. The outer grinding seat 16 surrounds the outer wall of the inner grinding seat 15 and has grinding columns evenly distributed on its surface to grind the raw materials. When the ground raw materials enter the cylinder 1, under the action of the inclined surface of the outer grinding seat 16, the raw materials enter between the inner grinding seat 15 and the outer grinding seat 16. The rotating inner grinding seat 15 and the outer grinding seat 16 grind the raw materials into powder.

[0028] A drive mechanism, located on the outer wall of cylinder 1, drives the rotating shaft 5 and the inner grinding seat 15. The drive mechanism includes a motor 6, a first connecting shaft 17, a first bevel gear 18, a second bevel gear 19, a second connecting shaft 20, a pulley 22, and a belt 23. The motor 6 is located on the side of the rotating shaft 5, and a fixing plate is provided at the lower end of the motor 6. The output end of the motor 6 is connected to the rotating shaft 5. The first connecting shaft 17 is fixedly connected to the lower end of the inner grinding seat 15, connecting the inner grinding seat 15 and the first bevel gear 18. The first bevel gear 18 is fixedly connected to the lower end of the first connecting shaft 17. When the first bevel gear 18 rotates, it can drive the inner grinding seat 15 at the upper end of the first connecting shaft 17. The second bevel gear 19 is located on the side of the first bevel gear 18 and meshes with it. The first bevel gear 18 is driven to rotate. The second connecting shaft 20 is fixedly connected to the side end of the second bevel gear 19. The pulley 22 is fixedly connected to the outer surface of the rotating shaft 5. Another pulley 22 is fixedly connected to the outer surface of the second connecting shaft 20. The pulley 22 can drive the belt 22 to rotate. The belt 23 is sleeved inside the pulley 22, and the other end of the belt 23 is sleeved inside the other pulley 22. When the rotating shaft 5 rotates, it can drive the second connecting shaft 20 to rotate synchronously. When the motor 6 is started, the rotating shaft 5 can perform preliminary processing on the raw materials inside the housing 4. Driven by the belt 23, the second connecting shaft 20 drives the second bevel gear 19 to rotate. The second bevel gear 19 drives the first bevel gear 18, which meshes with it, to rotate. When the first bevel gear 18 rotates, it can cause the inner grinding seat 15 at the upper end of the first connecting shaft 17 to rotate, thereby completing the rotation.

[0029] A fixing block 21 is connected to the middle of the second connecting shaft 20, and the fixing block 21 is fixedly connected to the middle of the side wall of the support column 3. One end of the fixing block 21 is fixedly connected to the outer wall of the support column 3. The fixing block 21 can prevent the second bevel gear 19 from failing to mesh with the first bevel gear 18 when the second connecting shaft 20 rotates, thereby preventing the inner grinding seat 15 from rotating.

[0030] Working principle: First, place the equipment in a suitable position. Then, place the raw material to be ground into the housing 4. Next, rotate the lead screw 24 to make the slider 9 slide inside the groove 8. When the slider 9 moves to the side of the groove 8, the spring 11 is relaxed, causing the connecting rod 10 to move upwards, thus making the grinding block 12 tightly contact the raw material. Then, start the motor 6, which drives the rotating shaft 5 to rotate. When the raw material block is smaller than the size of the groove 7, the raw material block will enter the cylinder 1 through the groove 7. When the grinding is complete... When the raw material is fed into the cylinder 1, it enters between the inner grinding seat 15 and the outer grinding seat 16 under the action of the inclined surface of the outer grinding seat 16. When the rotating shaft 5 rotates, the pulley 22 drives the belt 23 to drive the second connecting shaft 20 to drive the second bevel gear 19 to rotate. The second bevel gear 19 drives the first bevel gear 18 meshing with it to rotate. When the first bevel gear 18 rotates, it can make the inner grinding seat 15 at the upper end of the first connecting shaft 17 rotate. Finally, the rotating inner grinding seat 15 and the outer grinding seat 16 will grind the raw material into powder.

[0031] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
