[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A pulverizer includes a housing 1. A threaded rod 20 is rotatably connected to the top of the housing 1. An operating block 2 is fixedly mounted on the threaded rod 20. A threaded sleeve 21 is threadedly connected to the outside of the threaded rod 20. An adjusting plate 3 is fixedly mounted on the top of the threaded sleeve 21. A placement platform 4 is fixedly connected to the adjusting plate 3. A barrel 10 is mounted on the top of the placement platform 4. A mounting frame 11 is fixedly mounted on the top of the housing 1. A drive mechanism is mounted on the mounting frame 11. The drive mechanism includes a motor 12 fixedly mounted on the top of the mounting frame 11. A rotating shaft 14 located above the barrel 10 is rotatably connected to the bottom of the mounting frame 11. One end of the rotating shaft 14 passes through the bottom of the mounting frame 11 and is fixedly connected to the output shaft of the motor 12. A groove 15 is formed at the bottom of the rotating shaft 14. The top of the barrel 10... A mounting shaft 18 is rotatably connected to the mounting shaft 18. A mating block 16 is fixedly installed at one end of the mounting shaft 18 above the barrel 10. A crushing rod 19 located inside the barrel 10 is fixedly installed on the outer wall of the mounting shaft 18. The crushing rod 19 crushes the material inside the barrel 10 under the drive of the mounting shaft 18. A sliding groove 23 is opened on one side wall of the mounting frame 11. A slider 22 is fixedly installed on the outer wall of the adjusting plate 3. The slider 22 is adapted to the sliding groove 23 and is slidably connected to the sliding groove 23. The slider 22 and the sliding groove 23 cooperate to guide and limit the movement of the adjusting plate 3. Multiple abutments 13 are provided at the bottom of the mounting frame 11. The groove 15 is square. The mating block 16 is adapted to the groove 15. The mating block 16 and the groove 15 cooperate to enable the rotating shaft 14 to drive the mounting shaft 18 to rotate.

[0020] Auxiliary mechanisms are provided on both sides of the placement platform 4. The auxiliary mechanisms include a fixed frame 5 fixedly installed on the outer wall of the placement platform 4. Two telescopic rods 8 are fixedly installed on the side wall of the fixed frame 5 closest to the placement platform 4. The telescopic ends of the two telescopic rods 8 are fixedly connected to the same clamping block 7. The clamping block 7 is used to clamp the barrel 10 to prevent it from shaking during the powdering process. A spring 9 is fixedly connected between the clamping block 7 and the fixed frame 5. A second auxiliary block 17 is fixedly installed on the side wall of the clamping block 7 away from the placement platform 4. A first auxiliary block 6 located on the side of the clamping block 7 away from the placement platform 4 is fixedly installed at the bottom of the mounting frame 11. The vertical cross section of the first auxiliary block 6 is a right trapezoidal shape, and the vertical cross section of the second auxiliary block 17 is a right triangle shape.

[0021] In use, the barrel 10 containing the color powder is placed on the placement platform 4. Then, the operating block 2 is rotated to rotate the threaded rod 20. By setting the slider 22, the groove 23, and the threaded sleeve 21, the adjusting plate 3, the placement platform 4, the barrel 10, the clamping block 7, and the second auxiliary block 17 can move upward synchronously. During the upward movement of the second auxiliary block 17, its inclined surface will cooperate with the inclined surface of the first auxiliary block 6, thereby causing the clamping block 7 to move closer to the barrel 10, thus providing auxiliary clamping for the barrel 10. The telescopic rod 8 extends, and the spring... 9 is compressed, and then the barrel 10 continues to move upward and abuts against the stop block 13, thereby further improving the stability of the barrel 10. The mating block 16 and the square groove 15 cooperate with each other. By starting the motor 12, the rotating shaft 14 can be rotated, which in turn can make the mounting shaft 18 and the crushing rod 19 rotate to perform the powdering operation. After the powdering is completed, the barrel 10 moves downward by rotating the operating block 2 in the opposite direction. The inclined surface of the first auxiliary block 6 no longer cooperates with the inclined surface of the second auxiliary block 17. The clamping block 7 is reset by the spring 9, so that the barrel 10 is no longer clamped, and the barrel 10 can be removed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
