[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0023] Example 1
[0024] Reference Figure 1-4 As shown, a heat sink for a wet granulator comprises a granulator body 1 and a feeding port 2, a slide bar 10 is fixedly connected inside the granulator body 1, a screen barrel 3 is slidably arranged on the slide bar 10, a material pipe 4 is connected to the bottom end of the feeding port 2, the bottom end of the material pipe 4 is aligned with the upper position of the screen barrel 3, a motor 5 is installed at the top of the granulator body 1, one end of the output shaft of the motor 5 is connected to a first rotating shaft 6, the bottom end of the first rotating shaft 6 extends into the interior of the screen barrel 3 and is fixedly connected to a plurality of blades 7, a second rotating shaft 8 is rotatably arranged on one side of the granulator body 1, and a cam 9 acting on the screen barrel 3 is connected to the bottom end of the second rotating shaft 8;
[0025] Wherein, a transmission component acting on the second rotating shaft 8 is arranged between the first rotating shaft 6 and the second rotating shaft 8, and an elastic pushing component acting on the sieve barrel 3 is arranged between the sliding rod 10 and the sieve barrel 3;
[0026] After the powder is poured into the feeding port 2, the powder will slide down the material pipe 4 to the inside of the screen barrel 3. After the motor 5 is started, the output shaft of the motor 5 drives the first rotating shaft 6 to rotate, and the first rotating shaft 6 drives the blade 7 on its surface to rotate, so that the powder accumulated in the screen barrel 3 can be rotated and cut, and the larger agglomerated powder particles in the powder can be effectively ground and crushed. While the first rotating shaft 6 is rotating, the second rotating shaft 8 can be driven to rotate through the transmission component, and the second rotating shaft 8 drives the cam 9 to rotate. The screen barrel 3 sliding on the slide rod 10 can always be tightly against one side of the cam 9 through the elastic pushing component, so During the rotation of the cam 9, the raised part on the surface of the cam 9 can continuously push the screen barrel 3 horizontally, so that the screen barrel 3 continuously shakes horizontally along the slide bar 10, and the powder inside the screen barrel 3 can be shaken and screened. The fine powder particles in the powder will fall into the interior of the granulator body 1 through the sieve holes on the material pipe 4 under the action of shaking and screening, while the larger agglomerated powder particles cannot pass through the sieve holes on the material pipe 4 and are retained in the screen barrel 3 until they are cut into fine particles and fall into the granulator body 1, thereby ensuring that the powder added to the interior of the granulator body 1 is uniform and fine particles, thereby improving the molding quality of the pills.
[0027] For further information, please refer to Figure 2 , Figure 3 As shown, the transmission assembly includes a first gear 11 sleeved on the surface of the first rotating shaft 6, a second gear 12 sleeved on the surface of the second rotating shaft 8, and a toothed belt 13 arranged between the first gear 11 and the second gear 12;
[0028] When the first shaft 6 rotates, the first gear 11 on its surface will also rotate. During the rotation of the first gear 11, the second gear 12 will also rotate through the transmission action of the toothed belt 13, and finally the second shaft 8 will rotate under the driving action of the second gear 12.
[0029] For further information, please refer to Figure 4 As shown, the elastic push assembly includes a baffle 14 fixed to the surface of the slide rod 10, a connecting block 15 fixedly connected to the side wall of the screen barrel 3, and a spring 16 sleeved on the surface of the slide rod 10;
[0030] The spring 16 is in a compressed state, one end of the spring 16 abuts against the baffle 14, and the other end of the spring 16 abuts against the connecting block 15;
[0031] Since the spring 16 is in a compressed state and one end of the spring 16 is in contact with the baffle 14, the other end of the spring 16 will always produce an elastic pushing effect on the connecting block 15 to move toward the cam 9, so that the connecting block 15 is always in contact with one side of the cam 9 under this elastic pushing effect.
[0032] For further information, please refer to Figure 4 As shown, a roller 17 is installed on one side of the screen barrel 3 close to the cam 9, and the roller 17 is in rolling contact with the surface of the cam 9;
[0033] Since the roller 17 is in rolling contact with the surface of the cam 9, the cam 9 will not be subject to large frictional resistance from the side wall of the screen barrel 3 during its rotation, making the rotation process of the cam 9 smoother without generating large friction noise, and also avoiding wear on the side wall of the screen barrel 3.
[0034] For further information, please refer to Figure 1 As shown, an electric control cover plate 18 is installed at the top of the feeding port 2;
[0035] When the powder is poured into the feeding port 2, the electric control cover 18 can seal the top of the feeding port 2 in time to prevent the powder particles from floating into the surrounding environment, thereby saving the powder and avoiding pollution to the surrounding air.
[0036] Example 2
[0037] Further in the embodiments, please refer to Figure 1 and Figure 3 Shown, the auxiliary observation assembly includes a transparent observation port 19 provided on the top plate of the granulator body 1, and a lighting lamp 20 mounted inside the granulator body 1;
[0038] The lighting lamp 20 can provide lighting inside the granulator body 1. During the granulation process, it is convenient for the staff to directly observe the forming of the pills inside the granulator body 1 through the transparent observation port 19, which is conducive to controlling the granulation process and further ensuring the forming quality of the pills.
