[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, a stearic acid pulverizing device includes: a crushing chamber 20, which is a hollow cylindrical shape with a circular groove at the top and a motor fixedly installed at the bottom of the crushing chamber 20. A discharge pipe 22 is fixedly connected to the bottom of the outer wall of the crushing chamber 20. The discharge pipe 22 is a cylindrical shape and one end of the discharge pipe 22 can communicate with the cavity of the crushing chamber 20.

[0030] The crushing roller 21 is shaped like a frustum. The motor at the bottom of the crushing chamber 20 can drive the crushing roller 21 to rotate. The motor is electrically connected to the power supply. This is existing technology and will not be described in detail here.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a crushing structure is installed inside the crushing chamber 20 to accelerate the crushing speed of stearic acid. The crushing structure includes: a partition plate 30, a screen 31, a rotating shaft 34, and a slitting roller 37. The partition plate 30 is fixedly connected inside the crushing chamber 20, the screen 31 is fixedly connected to the wall of the partition plate 30, the rotating shaft 34 is rotatably connected to the top of the partition plate 30, and the bottom of the rotating shaft 34 can pass through the partition plate 30 and be fixedly connected to the crushing roller 21. The slitting roller 37 is rotatably connected to the wall of the rotating shaft 34 and can crush the stearic acid on the top of the partition plate 30.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the partition plate 30 is disc-shaped, and a semi-circular groove adapted to the size of the mesh 31 is opened on the top of the partition plate 30. Multiple circular holes are evenly opened on the top of the mesh 31. The slitting roller 37 is composed of a cylinder and a cylindrical arc surface with multiple annular blades fixedly connected to it. The slitting roller 37 is horizontally positioned above the partition plate 30. The rotating shaft 34 is cylindrical. The crushing structure also includes a ring rail 32, drive teeth 33, a rotating groove 35, a connecting piece 36, and an automatic wheel 38. The ring rail 32 is fixedly connected to the cavity of the crushing chamber 20, the drive teeth 33 are fixedly connected to the wall of the ring rail 32, and the rotating groove 35 is opened in… On the wall of the rotating shaft 34, the adapter 36 is rotatably connected in the rotating groove 35. The adapter 36 and one end of the slitting roller 37 are fixedly connected. The automatic wheel 38 is fixedly connected to the other end of the slitting roller 37. The ring rail 32 is circular. The drive tooth 33 is fixedly connected to the inner arc surface of the ring rail 32. The automatic wheel 38 is gear-shaped. The wall surface of the automatic wheel 38 can mesh with the drive tooth 33. The rotating groove 35 is circular. The adapter 36 is composed of a cylinder and a disk. The rotating groove 35 can adapt to the rotation of the cylinder of the adapter 36. The cylinder of the adapter 36 and the cylinder of the slitting roller 37 are fixedly connected.

[0033] In practical use, the power is turned on and the stearic acid to be crushed is fed into the cavity of the crushing chamber 20 through the circular groove at the top of the crushing chamber 20. After entering the crushing chamber 20, the stearic acid will fall onto the top of the partition plate 30. When the power is turned on, the motor will drive the crushing roller 21 to rotate, and the rotating crushing roller 21 will drive the rotating shaft 34 to rotate. When the rotating shaft 34 rotates, it will synchronously drive the slitting roller 37 and the automatic wheel 38 to rotate through the adapter 36. When the automatic wheel 38 rotates, it will mesh with the drive gear 33. The automatic wheel 38 rotates, which in turn drives the slitting roller 37 and the adapter 36 to rotate around the center of the rotating groove 35. The annular blades of the slitting roller 37 cut the stearic acid on the top of the partition plate 30 when they come into contact with the stearic acid as the rotating shaft 34 rotates. The cut stearic acid then falls from the circular groove on the top of the screen 31 to contact the wall of the crushing roller 21. The rotating crushing roller 21, in conjunction with the inner wall of the crushing chamber 20, crushes the stearic acid. The crushed stearic acid then leaks out from the discharge pipe 22.

[0034] In summary, by setting up a crushing structure that drives the slitting roller 37 to roll and rotate simultaneously, stearic acid with larger volumes is initially crushed before grinding, thereby effectively reducing the grinding time required by the grinding roller 21. Compared with the prior art, this solution does not have the problem of clogging, and this solution has a more efficient crushing efficiency.

[0035] like Figure 4 and Figure 5 As shown, the wall of the partition plate 30 is provided with an auxiliary structure, which includes a crushing cone 40 and a scraper 41. The crushing cone 40 is fixedly connected to the top of the rotating shaft 34, and the scraper 41 is fixedly connected to the bottom wall of the rotating shaft 34. The crushing cone 40 is conical, and the top of the crushing cone 40 is aligned with the circular groove at the top of the crushing chamber 20. The scraper 41 is a rectangular rod with circular notches on both sides of the wall, and the bottom of the scraper 41 can fit against the top of the partition plate 30.

[0036] In practical use, when stearic acid falls from the circular groove at the top of the crushing chamber 20, it will first be crushed by the crushing cone 40. As the rotating shaft 34 rotates, it will drive the scraper 41 to rotate synchronously. The rotating scraper 41 will scrape the stearic acid at the top of the partition plate 30 towards the screen 31.

[0037] In summary, by setting the crushing cone 40, the stearic acid entering the crushing chamber 20 can be directly crushed, which facilitates the crushing of stearic acid by the slitting roller 37. The scraper rod 41 can move the stearic acid crushed by the slitting roller 37 toward the screen 31, preventing the stearic acid from accumulating on the top of the partition plate 30.

[0038] Working principle: The power is turned on, and the stearic acid to be crushed is fed into the crushing chamber 20 through the circular groove at the top of the crushing chamber 20. After entering the crushing chamber 20, the stearic acid falls onto the top of the partition plate 30. When the power is turned on, the motor drives the crushing roller 21 to rotate. The rotating crushing roller 21 drives the rotating shaft 34 to rotate. When the rotating shaft 34 rotates, it synchronously drives the slitting roller 37 and the automatic wheel 38 to rotate through the adapter 36. When the automatic wheel 38 rotates, it meshes with the drive gear 33... The automatic wheel 38 rotates, which in turn drives the slitting roller 37 and the adapter 36 to rotate around the center of the rotating groove 35. The annular blade of the slitting roller 37 cuts the stearic acid on the top of the partition plate 30 when it comes into contact with the stearic acid as the rotating shaft 34 rotates. The cut stearic acid then falls from the circular groove on the top of the screen 31 to contact the wall of the crushing roller 21. The rotating crushing roller 21, in conjunction with the inner wall of the crushing chamber 20, crushes the stearic acid, which then leaks out from the discharge pipe 22.
