It is used for treating chest pain caused by qi stagnation and blood stasis, with chest tightness and precordialgia. Compound Danshen tablet is sugar-coated tablet or film-coated tablet, which is brown to brownish after removing the coating. It has aromatic odor and slightly bitter taste. In the production process of compound Danshen tablet, film-coated tablet preparation device is often used to coat the tablet core. Film-coated tablet refers to a thin layer of high molecular polymer coating on the tablet core, forming a film, which is called film coating. Film coating material includes film-forming material, plasticizer, solvent and other materials. Film-forming material is divided into gastric soluble film-forming material and enteric soluble film-forming material. In order to ensure the quality of the tablet and facilitate the use, the surface of the tablet core is coated with suitable coating material after tabletting, so that the drug in the tablet is isolated from the outside world, thereby achieving the purposes of preventing moisture, avoiding light, isolating air oxidation, enhancing the stability of drug preservation, masking the unpleasant smell of the tablet and reducing the irritation of the drug. Therefore, the tablet core needs to be coated.

A material seat 323 is fixedly installed at the tail end of the discharge channel 320, and a material collection frame 324 is movably installed inside the material seat 323.

[0019] In this embodiment, the material unloading rack 104 has a cross-section arranged in a star-shaped structure.

[0020] In practical use, the first motor 102 can drive the shaft 103 to rotate, and the shaft 103 can synchronously drive the unloading rack 104 to rotate. As the unloading rack 104 rotates, it can intermittently guide the tablet cores inside the feeding box 1 into the unloading box 101 until they fall onto the surface of the guide plate 201. This allows the tablet cores inside the feeding box 1 to fall down intermittently, thereby preventing the tablets inside the feeding box 1 from accumulating and flowing onto the surface of the guide plate 201, which would affect the subsequent tablet core coating effect.

[0021] In this embodiment, the guide plates 201 are distributed in an alternating structure inside the film forming box 2, and the atomizing nozzles 208 correspond one-to-one with the surface of the guide plates 201.

[0022] In practical use, the staggered distribution of the guide plates 201 allows the film core to move back and forth inside the film forming box 2. While the film core is moving, the pump body 204 draws the agent from the film agent box 202 into the extraction pipe 205, then from the extraction pipe 205 to the guide pipe 206, and then from the guide pipe 206 to each outlet pipe 207 until the agent is sprayed out by each atomizing nozzle 208. Thus, while the film core moves on the surface of the guide plates 201, the atomizing nozzles 208 can simultaneously spray the agent to contact the film core, forming a coating on its surface. As the film core moves back and forth on the guide plates 201 from top to bottom, the agent can be sprayed multiple times on the film core moving from top to bottom, avoiding uneven coating of the agent on the surface of the film core, thereby improving the uniformity of the agent spraying on the surface of the film core and improving the coating quality.

[0023] In this embodiment, the branch pipes 303 are distributed in pairs symmetrically on both sides of the main pipe 302, and the air outlets 304 are distributed in equal distances on the upper and lower sides of the branch pipes 303.

[0024] In practical use, the second motor 306 drives the second gear 307 to rotate, and the second gear 307 can synchronously drive the first gear 305 to rotate. The first gear 305 can synchronously drive the main pipe 302 and the branch pipe 303 to rotate, so that the branch pipe 303 can stir the coated core. At the same time, the hot air blower 315 can heat the external gas and transmit it into the air inlet pipe 314. Then, the hot air inside the air inlet pipe 314 can enter the main pipe 302 and the branch pipe 303 in sequence. Finally, the hot air can flow out evenly through the air outlets 304 on the branch pipe 303, thereby heating the inside of the drying chamber 3. Thus, while the branch pipe 303 is stirring the core, it can also heat the stirred core, so that the core can be heated evenly and the coating quality can be improved.

[0025] In this embodiment, the scraper 325 is adapted to the inner wall of the drying oven 3.

[0026] In practical use, the rotation of the main pipe 302 can synchronously drive the scraper 325 to rotate, so that the scraper 325 can rotate along the inner wall of the drying chamber 3. Thus, the scraper 325 can scrape off the cores adhering to the inner wall of the drying chamber 3, which can avoid the cores adhering inside and being inconvenient to handle.

[0027] In this embodiment, the material blocking plate 319 is adapted to the interior of the discharge port 316.

[0028] In practical use, the electric telescopic rod 318 can drive the material blocking plate 319 to move in and out. When the electric telescopic rod 318 drives the material blocking plate 319 in the discharge port 316 to move into the inner cavity 317, the discharge port 316 can be opened, so that the dried core can flow from the discharge port 316 into the discharge channel 320 until it flows into the collection frame 324.

[0029] In this embodiment, the two ends of the heat pipe 321 penetrate the interior of the drying box 3 and the discharge channel 320, respectively.

[0030] In practical use, the heat inside the drying chamber 3 can be introduced into the discharge channel 32 through the heat pipe 321, so that the wafer core can be dried again after flowing into the discharge channel 320, which can further improve the drying effect.

[0031] In this embodiment, the controller 5 is electrically connected to the first motor 102, the second motor 306, the pump body 204, the hot air blower 315, and the electric telescopic rod 318.

[0032] In practical use, the controller 5 can control the working status of the first motor 102, the second motor 306, the pump body 204, the hot air blower 315, and the electric telescopic rod 318.

[0033] The working principle of the compound Danshen tablet film-coating preparation device mentioned in this invention: In use, the first motor 102 can drive the shaft 103 to rotate, and the shaft 103 can synchronously drive the unloading rack 104 to rotate. As the unloading rack 104 rotates, it can intermittently guide the tablet cores inside the feeding box 1 into the unloading box 101 until they fall onto the surface of the guide plate 201. This allows the tablet cores inside the feeding box 1 to fall down intermittently, thereby preventing the tablets inside the feeding box 1 from accumulating and flowing onto the surface of the guide plate 201, which would affect the subsequent tablet core coating effect. Then, through the staggered distribution of the guide plates 201, the core film can move back and forth inside the film forming box 2. While the core film is moving, the pump body 204 draws the agent from the film agent box 202 into the liquid extraction pipe 205, and then from the liquid extraction pipe 205 to the liquid guide pipe 206, and then from the liquid guide pipe 206 to each liquid outlet pipe 207 until the agent is sprayed out by each atomizing nozzle 208. Thus, while the core film moves on the surface of the guide plates 201, the atomizing nozzles 208 can simultaneously spray the agent to contact the core film, so that the surface of the core film can be coated. Since the core film can move back and forth on the guide plates 201 from top to bottom, the agent can be sprayed on the core film multiple times, which can avoid uneven coating of the agent on the surface of the core film, thereby improving the uniformity of the agent coating on the surface of the core film and improving the coating quality. Then, the flake cores can flow into the drying chamber 3 from the bottom guide plate 201. The second motor 306 drives the second gear 307 to rotate, and the second gear 307 can simultaneously drive the first gear 305 to rotate. The first gear 305 can simultaneously drive the main pipe 302 and the branch pipe 303 to rotate, so that the branch pipe 303 can stir the coated flake cores. At the same time, the hot air blower 315 can heat the external air and send it into the air inlet pipe 314. Then, the hot air inside the air inlet pipe 314 can enter the main pipe 302 and the branch pipe 303 in sequence. Finally, the hot air can flow out evenly through the air outlets 304 on the branch pipe 303, thereby heating the inside of the drying chamber 3. Thus, the branch pipe 303 can heat the stirred flake cores while stirring them, so that the flake cores can be heated evenly, which can improve the coating quality. At the same time, the rotation of the main pipe 302 can synchronously drive the scraper 325 to rotate, so that the scraper 325 can rotate along the inner wall of the drying box 3. Thus, the scraper 325 can scrape off the cores adhering to the inner wall of the drying box 3, which can avoid the cores adhering inside and being inconvenient to handle. Then, the electric telescopic rod 318 can drive the material blocking plate 319 to move in and out. When the electric telescopic rod 318 drives the material blocking plate 319 in the discharge port 316 to move into the inner cavity 317, the discharge port 316 can be opened, so that the dried core can flow from the discharge port 316 into the discharge channel 320 until it flows into the collection frame 324. Meanwhile, the heat inside the drying chamber 3 can be transferred to the discharge channel 32 through the heat pipe 321, so that the wafer core can be dried again after flowing into the discharge channel 320, which can further improve the drying effect.
