[0024] The present utility model will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: an oral solid preparation raw material crushing device, including a cylindrical barrel 1 and a bracket 2 fixedly positioned relative to the barrel 1. The bracket 2 can be fixedly welded to the barrel 1 through a connecting rod, so that the relative positions of the barrel 1 and the bracket 2 are fixed. An inlet 3 is provided at one end of the barrel 1. A first baffle 4 and a second baffle 5 are slidably connected to the inner side wall of the barrel 1. A crushing unit 6 for crushing materials is rotatably connected between the first baffle 4 and the second baffle 5. A driving unit for moving the first baffle 4 and the second baffle 5 is installed on the bracket 2. The part outside the barrel 1 between the first baffle 4 and the second baffle 5 forms an outlet. A cleaning unit 8 for removing the materials between the first baffle 4 and the second baffle 5 is installed at the outlet of the barrel 1. When adding oral solid preparation raw materials, move the first baffle 4 and the second baffle 5 so that the inlet 3 is located between the first baffle 4 and the second baffle 5. When crushing the oral solid preparation raw materials, move the first baffle 4 and the second baffle 5 so that the first baffle 4, the second baffle 5 and the barrel 1 cooperate to form a closed cavity, and the raw materials are crushed in the closed cavity by the operation of the crushing unit 6. When removing the crushed raw materials, move the first baffle 4 and the second baffle 5 so that the first baffle 4 or the second baffle 5 is not in contact with the barrel 1. At this time, the part outside the barrel 1 between the first baffle 4 and the second baffle 5 forms an outlet. By moving the first baffle 4 and the second baffle 5, the crushed raw materials are removed. After the raw materials are removed, since the first baffle 4 or the second baffle 5 has cleaned the inner side wall of the barrel 1 during the sliding process relative to the barrel 1, only the cleaning unit 8 needs to clean the crushing unit 6 outside the barrel 1 and the opposite sides of the first baffle 4 and the second baffle 5, which is convenient for cleaning the crushed raw materials in the crushing equipment, and then crushing another oral solid preparation raw material, improving production efficiency.

[0026] In one embodiment, the distance between the first baffle 4 and the second baffle 5 is fixed, and the second baffle 5 is fixedly connected to the driving unit. By moving the second baffle 5 through the driving unit, the first baffle 4 can be synchronously moved.

[0027] In one embodiment, the driving unit includes a telescopic member 7. The telescopic member 7 is a suitable component such as an electric telescopic rod or a hydraulic pump. The fixed ends of the telescopic members 7 are bolted to the bracket 2, and the extended ends of the telescopic members 7 are bolted to the second baffle 5. By changing the length of the telescopic member 7, the second baffle 5 slides relative to the barrel 1, and at the same time, the first baffle 4 slides synchronously relative to the barrel 1.

[0028] In one embodiment, the telescopic members 7 are symmetrically distributed relative to the axis of the barrel 1, and the number of telescopic rods is suitable, such as two, which is convenient for the second baffle 5 to slide relative to the barrel 1.

[0029] In one embodiment, the crushing unit 6 includes a rotating shaft 6.1. The rotating shaft 6.1 is coaxial with the cylinder body 1. The rotating shaft 6.1 is rotatably connected to the first baffle 4 and the second baffle 5. Crushing blades 6.2 are bolted to the rotating shaft 6.1. By rotating the crushing blades 6.2, the raw materials are crushed.

[0030] In one embodiment, a first bearing 10 is installed between the part of one end of the rotating shaft 6.1 that extends through the first baffle 4 and the first baffle 4. The end of one end of the rotating shaft 6.1 is fixedly connected to the output shaft of the motor 12 through a coupling. The motor 12 is bolted to the first baffle 4. A second bearing 11 is installed between the part of the other end of the rotating shaft 6.1 that extends through the second baffle 5 and the second baffle 5. A retaining plate 13 is fixed to the end of the other end of the rotating shaft 6.1 with screws. The inner ring of the second bearing 11 is in contact and cooperation with the shaft shoulder of the rotating shaft 6.1 and the retaining plate 13. The side of the outer ring of the second bearing 11 away from the retaining plate 13 is in contact and cooperation with the second baffle 5. Sealing rings 14 are installed at the connection parts of the rotating shaft 6.1 with the first baffle 4 and the second baffle 5. The second bearing 11 is a bearing such as an angular contact ball bearing that is suitable for bearing both radial load and axial load at the same time, and the first bearing 10 is a suitable bearing such as a deep groove ball bearing. Through the cooperation of the retaining plate 13, the second bearing 11, the rotating shaft 6.1, and the second baffle 5, the axial movement of the rotating shaft 6.1 relative to the second baffle 5 is restricted. Through the cooperation of the motor 12, the rotating shaft 6.1, and the first baffle 4, the axial movement of the rotating shaft 6.1 relative to the first baffle 4 is restricted, so that the distance between the first baffle 4 and the second baffle 5 is fixed.

[0031] In one embodiment, an end cover 15 is bolted to the second baffle 5. The end cover 15 is in contact and cooperation with the outer ring of the second bearing 11. The relative position of the second bearing 11 is restricted by the end cover 15.

[0032] In one embodiment, the cylinder body 1 is arranged horizontally. The feed inlet 3 is located at the top of one end of the cylinder body 1. A collecting box 9 is arranged below the discharge outlet. The crushed raw materials removed are collected through the collecting box 9.

[0033] In one embodiment, the cleaning unit 8 includes a negative pressure device 8.1. A hose 8.2 is installed at the suction end of the negative pressure device 8.1. The negative pressure device 8.1 is a suitable device such as a suction fan or a negative pressure machine. By moving the hose 8.2, the crushing unit 6 located outside the cylinder body 1 and the opposite sides of the first baffle 4 and the second baffle 5 can be adsorbed and cleaned.

[0034] In one embodiment, the feed inlet 3 has a funnel-shaped structure. The feed inlet 3 and the cylinder body 1 are of an integral structure, which is convenient for materials to enter the cylinder body 1.

[0035] In one embodiment, the outer sides of the first partition plate 4 and the second partition plate 5 are made of rubber material, which facilitates the contact between the outer sides of the first partition plate 4 and the second partition plate 5 and the inner wall of the cylinder body 1, and facilitates the first partition plate 4 and the second partition plate 5 to partition the inner wall of the cylinder body 1.

[0036] Working principle: Move the first partition plate 4 and the second partition plate 5 so that the feed inlet 3 is located between the first partition plate 4 and the second partition plate 5. Feed materials into the cylinder body 1 through the feed inlet 3. Make the first partition plate 4 and the second partition plate 5 move to the right through the driving unit. The feed inlet 3 is located on the left side of the first partition plate 4, and the second partition plate 5 is located on the left side of the right end face of the cylinder body 1. Crush the raw materials through the operation of the crushing unit 6. During the crushing process, the first partition plate 4 and the second partition plate 5 can slide between the feed inlet 3 and the right end face of the cylinder body 1, which is convenient for cleaning the materials on the inner wall of the cylinder body 1 by the first partition plate 4 and the second partition plate 5, preventing the raw materials from sticking to the inner wall of the cylinder body 1, and facilitating the crushing of the raw materials. After the crushing is completed, make the first partition plate 4 and the second partition plate 5 move to the right through the driving unit. When the second partition plate 5 does not contact the inner wall of the cylinder body 1, the crushed raw materials enter the aggregate box 9. Continue to make the first partition plate 4 and the second partition plate 5 move to the right. The first partition plate 4 prompts the materials in the cylinder body 1 to move out, and at the same time, the first partition plate 4 cleans the inner wall of the cylinder body 1. When the right side face of the first partition plate 4 is on the right side of the right end face of the cylinder body 1, the materials are completely moved out of the cylinder body 1, and then the cleaning unit 8 can clean the crushing unit 6 located outside the cylinder body 1 and the opposite side faces of the first partition plate 4 and the second partition plate 5.

[0037] The above has described the present invention in detail through specific implementation manners and embodiments, but these do not constitute limitations on the present invention. Without departing from the principle of the present invention, those skilled in the art can also make many deformations and improvements, which should also be regarded as the protection scope of the present invention.
