Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production equipment technology, specifically a device for producing traditional Chinese medicine tablets. Background Technology

[0002] Chinese medicine tablets are a solid dosage form made by extracting, purifying, and concentrating Chinese medicinal materials, mixing them with suitable excipients, and then granulating and compressing them. They have advantages such as accurate dosage, convenient administration, and good stability. With the development of modern pharmaceutical technology, in order to improve the appearance of tablets, mask unpleasant odors, improve drug stability, or control the drug release site, one or more layers of coatings with different functions are often applied to the surface of the tablets. This process is called tablet coating.

[0003] The existing Chinese patent document "CN213191230U, a granulation device for the production of traditional Chinese medicine tablets" uses a nozzle to pour coating onto a guide plate. As the pill rolls, the material is adhered to the surface of the pill. Because the adhesion is carried out by the rolling of the pill itself, the material is adhered more evenly. In addition, multiple nozzles are set up to perform multiple adhesions, which makes the processing efficiency higher.

[0004] However, this device is mainly suitable for coating spherical pills. Since spherical pills can continuously tumble during rolling, it is beneficial for the coating to be evenly distributed. However, in actual production, many tablets have a flat structure. Due to shape limitations, these tablets cannot roll and tumble freely like spherical pills, making it difficult for the coating to adhere evenly to their surface, thus affecting the quality and effect of tablet coating.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please refer to Figure 1-4 ;

[0023] A traditional Chinese medicine tablet production apparatus includes a coating box 1, a liquid storage assembly 2 on the top of the coating box 1 containing a coating liquid, an opening 3 on one side of the coating box 1, and symmetrical extensions 11 at one end of the coating box 1 outside the opening 3. A first tablet conveyor belt 4 and a second tablet conveyor belt 5 are installed inside the coating box 1. The other ends of both the first and second tablet conveyor belts 4 and 5 are located outside the opening 3 and are fixedly connected to the two extensions 11. The end of the first tablet conveyor belt 4 outside the opening 3 is the starting end, used to place the tablets to be coated. The end of the second tablet conveyor belt 5 outside the opening 3 is used to output the coated tablets. The tablets complete the coating process by flowing along the first and second tablet conveyor belts 4 and 5. The first and second tablet conveyor belts 4 and 5 adopt an upper... The first tablet conveyor belt 4 is parallel to the bottom and staggered to the left and right. The end of the first tablet conveyor belt 4 is provided with an arc plate 13. The arc plate 13 is installed close to the belt surface of the first tablet conveyor belt 4 to ensure that it will not affect the normal transmission of the conveyor belt. When the tablet reaches the end of the first tablet conveyor belt 4, it will slide down along the arc plate 13. The end of the arc plate 13 is inclinedly connected to a straight plate 14. The bottom of the straight plate 14 extends to a position close to the second tablet conveyor belt 5. The sides of the arc plate 13 and the straight plate 14 are respectively fixedly connected to the inner walls of the two sides of the coating box 1. After the tablet passes through the arc plate 13, it slides down the straight plate 14 onto the second tablet conveyor belt 5, thereby realizing the flipping of the tablet. The coating box 1 is also provided with a coating assembly 6 connected to the liquid storage assembly 2. The coating assembly 6 can spray coating on the tablets on the first tablet conveyor belt 4 and the second tablet conveyor belt 5.

[0024] Specifically, the tablet is first placed at the beginning of the first tablet conveyor belt 4 and moves into the coating box 1 under the drive of the first tablet conveyor belt 4. During the operation of the first tablet conveyor belt 4, the coating component 6 evenly sprays the film liquid in the liquid storage component 2 onto the upper surface of the tablet to complete the first single coating. When the tablet reaches the end of the first tablet conveyor belt 4, due to the guiding effect of the arc plate 13, the tablet slides onto the inclined plate 14 and slides along the inclined plate 14 to the second tablet conveyor belt 5 below, thereby realizing the automatic flipping of the tablet. The flipped tablet continues to run on the second tablet conveyor belt 5, at this time the other side of the tablet is facing up, and the coating component 6 sprays coating on it to complete the double coating operation of the tablet. The double-coated tablet is output through the second tablet conveyor belt 5.

[0025] When workers pour a large number of tablets into the starting end of the first tablet conveyor belt 4, some tablets may be stacked. The tablets on top may obstruct the coating of the tablets below. To solve this problem, a baffle 12 is installed inside the coating box 1 above the first conveyor belt. The baffle 12 is located near the opening 3 and can only accommodate a single tablet at a time. The baffle 12 prevents the tablets stacked on top from moving. As the tablets below move forward with the first tablet conveyor belt 4, the tablets stacked on top are blocked by the baffle 12 and gradually separated, thus achieving a single-layer arrangement of tablets. This ensures that the subsequent coating process is not affected and guarantees the coating quality.

[0026] In this embodiment, a V-shaped collecting plate 7 is provided between the two extensions 11. The two ends of the collecting plate 7 are fixedly connected to the two extensions 11 respectively. The collecting plate 7 is located between the first tablet conveyor belt 4 and the second tablet conveyor belt 5, and is located at the starting end of the first tablet conveyor belt 4. The collecting plate 7 is used to collect tablets that fall off during the tablet placement process due to improper placement, and to prevent tablets from falling onto the second tablet conveyor belt 5 or scattering on the ground due to pouring in too many tablets at once.

[0027] In this embodiment, the liquid storage assembly 2 includes a liquid storage tank 21. The top of the liquid storage tank 21 is provided with an injection port 22 for adding coating liquid into the tank. To prevent external impurities from entering the tank and to prevent the coating liquid from splashing out during stirring, a sealing cap is threaded onto the injection port 22 to achieve a good sealing effect on the liquid storage tank 21. A motor 23 is detachably connected to the middle of the outer wall of one end of the liquid storage tank 21. The output end of the motor 23 extends into the liquid storage tank 21. A stirring column 24 is installed inside the liquid storage tank 21. The stirring column 24 is provided with first stirring blades 25 sequentially along the axial direction. The second stirring blade 26, the third stirring blade 27, and the fourth stirring blade 28 are installed at the same angle as the first stirring blade 25 and the second stirring blade 26, and at the same angle as the third stirring blade 27 and the fourth stirring blade 28. However, the installation directions of the third stirring blade 27 and the fourth stirring blade 28 are opposite to those of the first stirring blade 25 and the second stirring blade 26. This allows the coating liquid to flow in multiple directions during the stirring process, thereby achieving a more uniform and thorough mixing effect and preventing different components in the coating liquid from precipitating or separating due to prolonged standing time.

[0028] In this embodiment, the inner wall of the storage tank 21 is provided with a number of protrusions 29. The protrusions 29 play the role of a turbulence structure during the stirring process of the coating liquid. By disrupting the laminar flow state of the liquid, they promote the generation of eddies and turbulence inside the coating liquid, enhance the convection and mixing effect between the components, thereby accelerating the mixing speed, improving the uniformity of the coating liquid, and ensuring the quality of subsequent coating processes.

[0029] In this embodiment, the coating assembly 6 includes a diversion pipe 61, several electronic valves 62, and several electronic valves 63. The top of the diversion pipe 61 is provided with several connecting pipes 64 that communicate with the interior of the liquid storage assembly 2 to facilitate the delivery of the coating liquid. The electronic valves 62 are connected to the diversion pipe 61 via infusion pipes 65. Each electronic valve 62 has a nozzle 66 installed at its output end. The nozzles 66 are located above the first tablet conveyor belt 4, and are used to perform single-sided coating treatment on the tablets on the first tablet conveyor belt 4. 63 is connected to the diversion tube 61 through infusion tube 2 67. Infusion tube 2 67 has a U-shaped structure. One side of it extends from above the first tablet conveyor belt 4 to the outside of the coating box 1, and the other side extends from the outside of the coating box 1 to the position between the first tablet conveyor belt 4 and the second tablet conveyor belt 5 inside the coating box 1, and is connected to electronic valve 2 63. The output end of several electronic valves 2 63 is equipped with nozzle 2 68. The nozzle 2 68 is used to spray the tablets on the second tablet conveyor belt 5 that have completed the flipping operation, thereby completing the coating treatment of the other side of the tablets.
