[0034] Please see Figures 1-5 This utility model provides a technical solution: a drying device for capsule production, including a capsule drying box 1 and a capsule drying jar 14, a capsule drying assembly, which is located at the upper end of the capsule drying box 1, and a capsule turning assembly, which is located inside the capsule drying box 1. The capsule turning assembly includes a fixed frame 12, which is fixedly connected to the inside of the capsule drying box 1. A drying jar connecting shaft 13 is rotatably connected inside the fixed frame 12. A torsion spring 15 is sleeved on the surface of the drying jar connecting shaft 13. The two ends of the torsion spring 15 are fixedly connected to the fixed frame 12 and the drying jar connecting shaft 13, respectively. A servo motor 17 is fixedly connected to the right end of the capsule drying box 1. A rotating shaft 18 is fixedly connected to the output end of the servo motor 17. A toggle plate 19 is fixedly connected to the surface of the rotating shaft 18. The toggle plate 19 is flat. Three drying jar connecting plates 16 are fixedly connected to the surface of the capsule drying jar 14. The capsule drying jar 14 is shaped with a large middle and small ends. Multiple connecting strips 20 are symmetrically arranged inside the capsule drying jar 14.

[0035] There are two of each of the fixed frame 12, the drying tank connecting shaft 13 and the capsule drying tank 14, which are symmetrically arranged inside the capsule drying box 1. Both drying tank connecting shafts 13 are fixedly connected to the capsule drying tank 14. The capsule collection box 3 is slidably connected inside the capsule drying box 1.

[0036] The capsule drying assembly includes a filter box 4, which is fixedly connected to the upper end of the capsule drying chamber 1. A fan 9 is fixedly installed at the right end of the filter box 4. A connecting channel 5 is fixedly connected to the front end of the filter box 4. The connecting channel 5 is U-shaped. A first air inlet pipe 6 and an air outlet pipe 8 are fixedly connected to the upper end of the capsule drying chamber 1. The first air inlet pipe 6 is fixedly connected to the fan 9. A second air inlet pipe 7 is fixedly connected to the surface of the first air inlet pipe 6. Valves are installed inside the second air inlet pipe 7 and the air outlet pipe 8. Multiple heating tubes 10 are fixedly connected inside the connecting channel 5. Multiple exhaust ports 11 are opened on the inner wall of the capsule drying chamber 1. Multiple exhaust ports 11 are also opened on the inner side of the connecting channel 5.

[0037] The heating tube 10 and the exhaust port 11 are divided into two groups and are symmetrically arranged on both sides of the capsule drying box 1.

[0038] Multiple filters are installed inside filter box 4.

[0039] The capsule drying tank 14 has ventilation holes on its surface, a feed inlet 21 at the upper end of the capsule drying tank 14, a first baffle 22 is snapped into the inside of the feed inlet 21, and a discharge outlet 23 at the lower end of the capsule drying tank 14, a second baffle 24 is snapped into the inside of the discharge outlet 23.

[0040] The capsule drying chamber 1 has two hinged doors 2 at its front end.

[0041] When using this device, first open the door 2, remove the first baffle 22 from the inside of the inlet 21, and add the capsules to be dried into the capsule drying tank 14 through the inlet 21. Then, snap the first baffle 22 onto the inlet 21, close the door 2, open the valves of the second air inlet pipe 7 and the fan 9, and start the fan 9 to introduce air into the filter box 4 and the connecting channel 5 through the second air inlet pipe 7. The air is filtered through the filter screen in the filter box 4. Connect the power supply to the heating tube 10 to heat the air. Then, the hot air is introduced into the capsule drying tank 1 through the connecting channel 5 and the exhaust port 11 on the surface of the capsule drying tank 1, and enters the capsule drying tank 14 through the vent holes on the surface of the capsule drying tank 14 to facilitate the drying of the capsules. The moisture on the capsule surface is heated to accelerate evaporation, and then the hot air and moisture are discharged from the air outlet pipe 8. During the process of drawing air into the capsule drying chamber 1 through the fan 9, the setting of the first air inlet pipe 6 facilitates the circulation of hot air inside the capsule drying chamber 1. When the air is heated by the heating pipe 10, the preheating time is reduced, making the entire drying process faster and more efficient. This not only saves time but also improves production efficiency. At the same time, it reduces temperature fluctuations, making the entire drying process more stable and further improving energy utilization efficiency. During the circulation of hot air, the circulation efficiency of hot air is further improved by closing the second air inlet pipe 7, which facilitates the drying of capsules.

[0042] During the capsule drying process, the servo motor 17 is activated to drive the rotating shaft 18 to rotate. The rotating shaft 18 drives the actuating plate 19 to rotate. During the rotation of the actuating plate 19, the actuating plate 19 presses against the drying tank connecting plate 16 on the surface of the capsule drying tank 14, causing the drying tank connecting plate 16 to rotate around the drying tank connecting shaft 13 under the pressure of the actuating plate 19. The drying tank connecting plate 16 drives the capsule drying tank 14 to rotate around the drying tank connecting shaft 13. Since the actuating plate 19 is flat, after rotating 90 degrees, the actuating plate 19 separates from the drying tank connecting shaft 13. During the rotation of the capsule drying tank 14, the drying tank connecting shaft 13 rotates, and the torsion spring 15 on its surface is torsioned during the rotation. When the actuating plate 19 separates from the drying tank connecting plate 16, the capsule drying tank 14 is subjected to the elastic force of the torsion spring 15. Under the action of the mechanism, the capsule drying tank 14 is reset, that is, rotated in the opposite direction, causing it to swing back and forth around the connecting shaft 13. The capsule drying tank 14, along with its internal connecting strip 20, rotates back and forth, and the connecting strip 20 moves the capsules inside. The shape of the capsule drying tank 14, which is larger in the middle and smaller at both ends, facilitates the stirring of the capsules inside the capsule drying tank 14 and facilitates the redistribution of the capsules inside the capsule drying tank 14. Through the stirring of the connecting strip 20, the movement of the capsules inside the capsule drying tank 14 becomes more intense, which helps to accelerate the evaporation of moisture on the surface of the capsules. At the same time, the presence of the connecting strip 20 also increases the contact area between the capsules and the hot air, further improving the drying rate and facilitating the uniform drying of the capsules. By repeating the above process, the capsule drying tank 14 can continuously rotate back and forth, which is convenient for drying the capsules.

[0043] Because the actuating plate 19 will separate from the drying tank connecting plate 16 during the rotation process, when the actuating plate 19 needs to contact the drying tank connecting plate 16, since there are three drying tank connecting plates 16 fixedly connected to the surface of the capsule drying tank 14, it is only necessary to control the actuating plate 19 to rotate to a horizontal position by the servo motor 17. When the capsule drying tank 14 reciprocates, the drying tank connecting plate 16 on its surface will collide with the actuating plate 19. It is only necessary to start the servo motor 17 again to actuate the drying tank connecting plate 16 through the actuating plate 19, so as to facilitate the repeated reciprocating rotation of the capsule drying tank 14 and the repeated stirring of the capsules.

[0044] After the capsules are dried, the power supply to the heating tube 10 is disconnected, causing the heating tube 10 to stop heating. The fan 9 then expels external air into the capsule drying chamber 1 through the second air inlet 7, while the air inside the capsule drying chamber 1 is discharged through the air outlet 8, facilitating cooling of the capsule drying chamber 1. Then, the chamber door 2 is opened, and the second baffle 24 is removed from the discharge port 23 to facilitate the discharge of capsules from the capsule drying tank 14. The capsules are then collected using the capsule collection box 3. Since the capsules are blocked by the connecting strip 20 during discharge, the capsule drying tank 14 is manually rotated around the drying tank connecting shaft 13, allowing the capsules to be guided by the connecting strip 20 and discharged to the discharge port 23, facilitating the collection of any remaining capsules.

[0045] Furthermore, the reciprocating rotation of the capsule drying tank 14 and the reciprocating agitation of the capsules by the connecting strip 20 facilitate the agitation of the capsules inside the capsule drying tank 14, making it easier to redistribute the capsules inside the capsule drying tank 14. The agitation by the connecting strip 20 makes the movement of the capsules inside the capsule drying tank 14 more intense, which helps to accelerate the evaporation of moisture on the capsule surface. The presence of the connecting strip 20 also increases the contact area between the capsules and the hot air, further improving the drying rate and facilitating uniform drying of the capsules, thus enhancing the practicality and convenience of the device.

[0046] The arrangement of the second air inlet pipe 7, the air outlet pipe 8, and the fan 9 facilitates the circulation of air inside the capsule drying chamber 1 during air flow. When the air is heated by the heating pipe 10, the preheating time is reduced, making the entire drying process faster and more efficient. This not only saves time but also improves production efficiency. At the same time, it reduces temperature fluctuations, making the entire drying process more stable and improving energy utilization efficiency.
