Description

Technical Field

[0001] The utility model relates to the technical field of medicine processing, in particular to a medicine coating device. Background Art

[0002] The purpose of coating (also called film coating or coating) during drug processing is to protect drugs from the external environment and improve the stability, storage resistance and ease of taking of drugs. Coating can protect drugs from external factors such as moisture, light, oxygen, temperature changes and chemicals, prevent the quality of drugs from being damaged or changed, and extend the shelf life of drugs; at the same time, coating can reduce the contact between drugs and the external environment, prevent drugs from chemical reactions or decomposition due to changes in external conditions, and improve the stability of drugs.

[0003] In pharmaceutical processing, coating machines are usually used to coat drugs. The workflow is usually as follows: First, the drug needs to be prepared, usually in solid form, such as tablets, capsules or granules. According to the characteristics of the drug and the desired coating effect, an appropriate coating solution is prepared. This solution usually contains polymers, plastics, pigments and other additives to provide the desired appearance, stability and release characteristics.

[0004] The drug enters the coating area through the conveying system of the coater. Here, the surface of the drug is coated or covered with the coating solution. The coating process can be carried out by different methods, including spraying, dipping or spin coating. After coating, the drug usually needs to go through a curing and drying process to ensure that the coating layer is stable and not easily damaged. This is usually achieved by heating or ventilation drying.

[0005] During the coating process, the drugs will continue to tumble in the coating machine to achieve a uniform coating effect. However, some coating solution may remain in the coating machine, and since the settings in the coating machine are relatively complicated, it is difficult to remove the residual coating solution in the coating machine. The residual coating solution may cause cross-contamination between drugs and affect the quality and safety of the drugs. Therefore, it does not meet the existing needs. We have proposed a drug coating equipment. Utility Model Content

[0029] Embodiment 1: This embodiment is intended to promote the solution of the problem that the setting in the coating machine is relatively complicated, so it is difficult to remove the residual coating solution in the coating machine, and the residual coating solution may cause cross contamination between drugs, affecting the quality and safety of the drugs. Please refer to Figure 1 - Figure 7 , a drug coating device, including a control box 100, a feeding tube 200, a coating cylinder 300 and a sprayer 400.

[0030] The coating drum 300 is arranged on the control box 100, the sprayer 400 is installed on the side of the control box 100, one end of the feeding tube 200 is inserted into the coating drum 300, and the other end of the feeding tube 200 is plugged into the control box 100, the sprayer 400 is connected to the spray tube 410, and the end of the spray tube 410 is inserted into the coating drum 300, a stirring rod 310 is arranged in the coating drum 300, a plurality of stirring plates 320 are installed outside the stirring rod 310, and a cleaning component 500 is arranged in the stirring plate 320.

[0031] The cleaning assembly 500 includes a storage box 510 installed at the end of the stirring plate 320, a push plate 511 is provided in the storage box 510, a plurality of cleaning brushes 512 are installed on the push plate 511, a cavity 520 is provided in the stirring plate 320, the cavity 520 is connected to the storage box 510, a push rod 521 for pushing the push plate 511 is provided in the cavity 520, and a first inclined block 522 is installed at the end of the push rod 521.

[0032] The cleaning assembly 500 further includes an active cavity 530 provided in the stirring rod 310, the active cavity 530 is communicated with the cavity 520, a driving rod 531 is inserted in the active cavity 530, a second inclined block 532 corresponding to the first inclined block 522 is fixedly installed on the side of the driving rod 531, and the first inclined block 522 fits the second inclined block 532. An internal threaded ring 311 is provided in the stirring rod 310, and an external threaded ring 534 corresponding to the internal threaded ring 311 is provided outside the driving rod 531, and the external threaded ring 534 is threadedly installed with the internal threaded ring 311.

[0033] The storage box 510 is provided with a plurality of through holes 513 for the cleaning brush 512 to pass through. The cleaning brush 512 is configured as a rubber brush, and the diameter of the through hole 513 corresponds to the diameter of the cleaning brush 512. A limit rod 514 is provided in the storage box 510, and a first spring 515 is provided on the outer sleeve of the limit rod 514. One end of the first spring 515 abuts against the inner wall of the storage box 510, and the other end of the first spring 515 abuts against the side wall of the push plate 511. The end of the stirring rod 310 is connected to the motor 110 through the coating cylinder 300, and the motor 110 is located in the control box 100.

[0034] After the coating machine has finished coating the medicine and taken out the finished medicine, the driving rod 531 is manually rotated clockwise. The driving rod 531 is pushed inward due to the drive of the external threaded ring 534 and the internal threaded ring 311. As the drive moves, the second inclined block 532 moves synchronously and pushes the first inclined block 522. Then, as the first inclined block 522 moves, the push rod 521 drives the push plate 511 to release the cleaning brush 512 from the storage box 510. At this time, the motor 110 is turned on again through the control box 100 so that the stirring plate 320 drives the cleaning assembly 500 to rotate, thereby cleaning the residual medicine in the coating cylinder 300.

[0035] After cleaning is completed, the driving rod 531 is rotated counterclockwise to make the driving rod 531 return to its original position.
