Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A continuous drug dryer includes a base 1, a first conveyor belt 8 and a second conveyor belt 11 for conveying drugs, and a conveying mechanism 5 for transferring drugs on the surface of the second conveyor belt 11 into the interior of the first conveyor belt 8. The first conveyor belt 8 is disposed above the second conveyor belt 11, and a drying mechanism is also disposed above the first conveyor belt 8.

[0024] The second conveyor belt 11 is rotatably disposed inside the base 1. The output rod inside the second conveyor belt 11 passes through the side wall of the base 1 and is keyed to the output shaft of the second motor 10. The top surface of the base 1 is also provided with a support cover 2. The first conveyor belt 8 is rotatably disposed inside the support cover 2. The output rod inside the first conveyor belt 8 passes through the side wall of the support cover 2 and is keyed to the output shaft of the first motor 9.

[0025] The first conveyor belt 8 and the second conveyor belt 11 have opposite conveying directions, with the second conveyor belt 11 facing the conveying mechanism 5. The first conveyor belt 8 is positioned above the second conveyor belt 11, and the second conveyor belt 11 has opposite conveying directions, with the second conveyor belt 11 facing the conveying mechanism 5. This facilitates the conveying of the drug via the first conveyor belt 8, which is then dried by the dryer 3 above. When the first conveyor belt 8 conveys the drug to the end of the conveying mechanism 5, the drug falls from the surface of the first conveyor belt 8 onto the surface of the second conveyor belt 11. The second conveyor belt 11 then moves the drug on its surface to the end near the conveying mechanism 5, where it falls into the receiving hopper 6. From there, the drug enters the conveying mechanism 5, where it undergoes a secondary transfer back to the surface of the first conveyor belt 8. This continuous drying process eliminates the need for manual operation, improving drying efficiency.

[0026] Both ends of the outer arc surfaces of the first conveyor belt 8 and the second conveyor belt 11 are provided with baffles 12 to prevent drugs from falling off. The baffles 12 are also provided at both ends of the outer arc surfaces of the first conveyor belt 8 and the second conveyor belt 11 to prevent drugs from falling off the surfaces of the first conveyor belt 8 and the second conveyor belt 11, thus avoiding drug waste.

[0027] A receiving hopper 6 is located inside the base 1 near the conveying mechanism 5 at the end of the second conveyor belt 11. The outlet of the receiving hopper 6 is connected to the conveying mechanism 5. The receiving hopper 6 is located at the end of the second conveyor belt 11, and the outlet of the receiving hopper 6 is connected to the conveying mechanism 5, so that the medicine falling from the surface of the second conveyor belt 11 into the receiving hopper 6 can be transferred to the top of the first conveyor belt 8 by the conveying mechanism 5 for secondary drying of the medicine and to improve drying efficiency.

[0028] The material conveying mechanism 5 includes a material conveying cylinder 15 and an auger 16. The auger 16 is rotatably disposed inside the material conveying cylinder 15. The top end of the auger 16 passes through the top surface of the material conveying cylinder 15 and is keyed to the output shaft of the rotary motor 18. The outer arc surface above the rotary motor 18 is connected to a discharge hopper 17. The port of the discharge hopper 17 is located above the first conveyor belt 8.

[0029] The material transfer cylinder 15 is provided with a fixing frame 14 on the side wall of both the support cover 2 and the base 1. The fixing frame 14 is fixedly sleeved on the outer arc surface of the material transfer cylinder 15.

[0030] Secondly, the rotary motor 18 drives the auger 16 to rotate inside the feed cylinder 15, so that the material entering the bottom of the feed cylinder 15 is transported by the auger 16 to the inside of the feed hopper 17 that is connected above the feed cylinder 15. The feed hopper 17 then transfers the material to the surface of the first conveyor belt 8, thereby achieving continuous drying of the drug and improving drying efficiency.

[0031] The drying mechanism includes a dryer 3, which is located on the top of the support cover 2. The air outlet at the bottom of the dryer 3 is located on the inner top surface of the support cover 2. Air ducts 4 are provided on both sides of the air outlet of the dryer 3. The two side walls of the support cover 2 are provided with windows 13 below the first conveyor belt 8. The outside of the windows 13 is provided on the side walls of the support cover 2. The bottom ends of the air ducts 4 are connected to the air ducts 7.

[0032] Finally, the air outlets on both sides of the dryer 3 are connected to the air duct 4 respectively. The air duct 4 is connected to the air hood 7 outside the window 13 opened on the side wall of the end support cover 2, so that hot air can be transmitted to the inside of the air hood 7 through the air duct 4 to dry the medicine that falls onto the surface of the second conveyor belt 11. This achieves drying of the medicine from multiple aspects and improves the drying quality.

[0033] Working principle: The medicine is placed above the first conveyor belt 8, and the first motor 9 and the second motor 10 are started simultaneously. The first motor 9 drives the first conveyor belt 8 to start, so that the first conveyor belt 8 carries the medicine to the end away from the conveying mechanism 5. The medicine is dried by the dryer 3 above. After the medicine is carried by the first conveyor belt 8 to the surface of the second conveyor belt 11, the second conveyor belt 11 carries the medicine towards the conveying mechanism 5, so that the medicine falls into the inside of the receiving hopper 6. Finally, the material is transferred to the top of the first conveyor belt 8 by the conveying mechanism 5 for continuous drying of the medicine, which improves the drying efficiency.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
