Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] As Figure 1 shown, a granulating device for traditional Chinese medicine formula granules includes a batching mechanism, a stirring mechanism 1 and a granulating mechanism 4. The stirring mechanism 1 is installed on a support column. The discharge pipe 2 of the stirring mechanism 1 is connected to the screw feeder 3 on the support column, and the screw feeder 3 is connected to the granulating mechanism 4 on the support column;
[0023] A temperature sensor 5 for detecting the temperature of the material is installed inside the granulating mechanism 4. By arranging the temperature sensor 5 in the granulating mechanism 4, the temperature sensor 5 adopts an infrared sensor and is aligned with the material to monitor the temperature of the material during the granulating process, and the temperature of the material is reduced by the circulation of water in the water tank 7 in the cooling chamber 6. A cooling chamber 6 is arranged in the box body of the stirring mechanism 1. The bottom of the cooling chamber 6 is connected to the water tank 7 through the water inlet pipe 9, and the water tank 7 is communicated with the top of the cooling chamber 6 through the overflow pipe 10. A pump body 8 for pumping water into the cooling chamber 6 is arranged on the water tank 7. By arranging the cooling chamber 6 on the stirring mechanism 1 and cooperating with the water tank 7, the water inlet pipe 9 and the overflow pipe 10 to cool the traditional Chinese medicine formula granules.
[0024] A heating plate can also be arranged in the water tank 7 to increase the water temperature. When the temperature of the material in the granulating mechanism 4 is too low, water bath heating of the material in the stirring mechanism 1 is realized, so as to realize temperature control. Specifically, a PLC control system is adopted, which is not shown in the figure. It solves the problem that the granulating temperature of the existing traditional Chinese medicine formula granules will affect the thermal stability of the material, and too high or too low temperature may affect the quality of the granules.
[0025] The batching mechanism includes a first batching box 11 and a second batching box 15. On both the first batching box 11 and the second batching box 15, there are screw feeders 12 for feeding the mixing mechanism 1. At the bottom of the screw feeder 12, there is a feeding port 14. Since the raw materials of traditional Chinese medicine need to be proportioned, setting two batching boxes can perform proportioning and mixing.
[0026] At the bottom of both the first batching box 11 and the second batching box 15, there are weighing sensors 13. The weighing sensors 13 are used to measure the amount of materials added from the batching mechanism into the mixing mechanism 1. The weighing sensors 13 can weigh the total weight of the batching box, the screw feeder 3 and the materials. By measuring the reduction in the total weight, the added amount of materials can be finally obtained. Thus, the added amount of each ingredient can be monitored and controlled.
[0027] At the top of the mixing mechanism 1, there is a mixing motor 16. The output shaft of the mixing motor 16 is connected to the mixing frame 17 inside the mixing mechanism 1. By driving the mixing motor 16, various different materials are mixed and stirred to ensure the uniform mixing of traditional Chinese medicine formula granules.
[0028] The bottom of the granulating mechanism 4 is connected to the screening box 18 through a discharge port. There is a valve on the discharge port. The screening box 18 is used to screen out materials with particle sizes larger and smaller than the requirements. By setting a valve on the discharge port, the discharge of the pills or tablets after granulation can be controlled. Through intermittent discharging, it is convenient for subsequent screening and detection.
[0029] As Figure 2 shown, in the screening box 18, a first sieve plate 19 and a second sieve plate 20 are arranged from top to bottom. The screening aperture of the first sieve plate 19 is the aperture required for granulation. The screening aperture of the second sieve plate 20 is smaller than the aperture required for granulation. In the screening box 18, a finished product pipe 21 is arranged between the first sieve plate 19 and the second sieve plate 20. Materials larger than the granulation requirement size are screened out through the first sieve plate 19. Materials smaller than the aperture required for granulation are screened out through the second sieve plate 20. Materials meeting the aperture requirement for granulation in the middle are output through the finished product pipe 21.
[0030] Above the first sieve plate 19 in the screening box 18, there is a first air pump 22. After the valve at the discharge port is closed, the first air pump 22 drives the air flow on the first sieve plate 19, thereby driving the screening of the materials on the first sieve plate 19 by wind power and also driving the screening of the materials on the second sieve plate 20.
[0031] On the screening box 18, a first return pipe 23 is connected to the side of the first sieve plate 19. A valve is provided on the first return pipe 23. The first return pipe 23 is used to discharge the materials in the screening box 18 that are larger than the size required for granulation. When the valve on the return pipe is closed, the first air pump 22 can drive the material screening. After the screening is completed, the valve on the first return pipe 23 is opened, and the materials on the first sieve plate 19 that are larger than the aperture required for granulation are blown into the first return pipe 23 by the first air pump 22, facilitating the subsequent material screening. After the screening is completed, the valve at the discharge port is opened for the next batch of material screening.
[0032] On the bottom of the second sieve plate 20 of the screening box 18, a second return pipe 24 is connected. The second return pipe 24 can discharge the materials in the screening box 18 that are smaller than the size required for granulation under the action of the wind force of the first air pump 22.
[0033] Both the first return pipe 23 and the second return pipe 24 are connected to the second air pump 25. The second air pump 25 is connected to the stirring mechanism 1 through a third return pipe 26. The second air pump 25 can drive the materials on the first sieve plate 19 that are larger than the aperture required for granulation and the materials at the bottom of the second sieve plate 20 that are smaller than the aperture required for granulation to be transported to the stirring mechanism 1 for re-stirring and granulation under the action of negative pressure, saving materials.
[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
