Specific embodiments
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0023] Please refer to Figures 1-8This utility model provides a technical solution: a tablet pulverizing device with an anti-clogging structure, including a support frame 1, a pulverizer 2 fixedly mounted on the upper surface of the support frame 1, a feed hopper 3 fixedly mounted at the feed inlet of the pulverizer 2, a first motor 4 fixedly mounted on one side surface of the feed hopper 3, a connecting shaft 5 fixedly connected to the output end of the first motor 4, a partition 6 sleeved on the outer wall of the connecting shaft 5, a discharge hopper 7 fixedly mounted at the lower discharge outlet of the pulverizer 2, a spring 8 fixedly connected to the upper surface of the discharge hopper 7, and another spring 8... A screen 9 is fixedly connected to one end of the pulverizer 2. A vibrating motor 10 is fixedly installed on one side of the outer wall of the screen 9. A support base 14 is fixedly installed on one side of the outer wall of the pulverizer 2. A conveying pipe 15 is fixedly installed through one end of the support base 14. A second motor 16 is fixedly installed on the lower surface of the conveying pipe 15. A screw rod 17 is fixedly connected to the output end of the second motor 16. A discharge pipe 18 is fixedly installed at the opening on the side of the conveying pipe 15 away from the second motor 16. The pulverizer 2 is connected to the support frame 1, the pulverizer 2, the feed hopper 3, the first motor 4, the connecting shaft 5, and the partition plate 6. The arrangement of the feed hopper 7, spring 8, screen 9, vibrating motor 10, support base 14, conveying pipe 15, second motor 16, screw rod 17, and discharge pipe 18 is as follows: During crushing, the tablets are first fed into the feed hopper 3. The first motor 4 causes the connecting shaft 5 to rotate with the partition plate 6, allowing the tablets to smoothly enter the crusher 2 without clogging in the feed hopper 3. During the crushing process, the tablets fall through the screen 9, and incompletely crushed tablets are blocked. The inner wall of the screen 9 has a certain inclination angle. The vibrating motor 10 drives the screen... When vibrating, the tablets that are not completely crushed and have not passed through the screen 9 can be conveyed to the side closer to the conveying pipe 15. The vibrating motor 10 makes the screen 9 vibrate, which can avoid the screen holes from clogging and also improve the screening effect. These tablets will enter the conveying pipe 15, and then the second motor 16 will make the screw 17 rotate, which can convey the incompletely crushed tablets upward. Finally, they will re-enter the crusher 2 through the discharge pipe 18 for further crushing and finally be discharged from the hopper 7. This ensures that all tablets can be completely crushed and the crushing effect is better.
[0024] Furthermore, the screen 9 has a certain tilt angle, with the end closer to the conveying pipe 15 being lower and the end farther away from the conveying pipe 15 being higher. Through the setting of the screen 9, the screen 9 can block the incompletely crushed tablets, ensuring the crushing effect.
[0025] Furthermore, the screen 9 is set inside the pulverizer 2 and corresponds to the discharge port of the pulverizer 2. The discharge port of the screen 9 corresponds to the upper end of the feed hopper 7. With the setting of the partition 6, the tablets can enter the pulverizer 2 in batches when the partition 6 rotates, which can effectively prevent the tablets from clogging in the feed hopper 3.
[0026] Furthermore, the screen 9 is set inside the crusher 2 and corresponds to the discharge port of the crusher 2. The discharge port of the screen 9 corresponds to the upper end of the hopper 7. Through the setting of the hopper 7 and the screen 9, the crushed tablets are screened by the screen 9 under the action of the screen 9. At the same time, the screen 9 can be vibrated by the vibration motor 10. The spring 8 also plays a certain degree of shock absorption effect to prevent the vibration amplitude of the screen 9 from being too large.
[0027] Furthermore, a first slider 11 is fixedly installed on both sides of the surface of the screen 9, and a first groove 12 is opened on the inner surface of the crusher 2 corresponding to the first slider 11. Through the arrangement of the screen 9, the first slider 11, the crusher 2 and the first groove 12, the first slider 11 can limit the vibration of the screen 9 when sliding in the first groove 12, so that the screen 9 can slide up and down in the crusher 2.
[0028] Furthermore, the discharge pipe 18 is positioned above the feed hopper 3, and the outlet end of the discharge pipe 18 corresponds to the inlet of the feed hopper 3. Through the arrangement of the discharge pipe 18 and the feed hopper 3, tablets that are not fully pulverized can be fed back into the feed hopper 3 by the discharge pipe 18 to be pulverized again.
[0029] Furthermore, the screen 9 is provided with second grooves 13 on both sides of the outer feed port of the pulverizer 2. The inner wall of the conveying pipe 15 near the feed port is fixedly installed with second sliders 19. The second sliders 19 and the second grooves 13 are slidably connected. With the setting of the second sliders 19 and the second grooves 13, the second sliders 19 can limit the vibration of the screen 9 when sliding in the second grooves 13, so that the tablets blocked by the screen 9 can smoothly enter the conveying pipe 15.
[0030] Working principle: During crushing, the material is first fed into the feed hopper 3. After entering the feed hopper 3, the material is blocked by the partition plate 6. The first motor 4 drives the connecting shaft 5 to rotate the partition plate 6. During the rotation of the partition plate 6, the material is fed into the feed inlet of the crusher 2 in an orderly manner. Then the crusher 2 crushes the material. The crushed material falls downward through the discharge port at the bottom of the crusher 2. During the falling process, the crushed material will be screened by the screen 9. The completely crushed material falls through the screen holes and is discharged through the discharge hopper 7, while the incompletely crushed material is blocked. The screen 9 has a certain tilt angle. When the vibrating motor 10 vibrates the screen 9, it can convey the incompletely crushed material that has not passed through the screen 9 to the side closer to the conveying pipe 15. While vibrating, this material will enter the conveying pipe 15. Then the second motor 16 will make the screw 17 rotate, which can convey the incompletely crushed material upward. Finally, it will be sent into the feed hopper 3 through the discharge pipe 18. With the help of the partition 6, it will re-enter the crusher 2 for crushing again until it is crushed enough to pass through the screen 9. Finally, it will be discharged from the discharge hopper 7. This completes a tablet crushing device with an anti-clogging structure.
[0031] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
