Description

BACKGROUND OF THE INVENTION Field of Invention The invention relates to a modular drug tablet manufacturing system capable of quickly replenishing drug powder and disposing drug powder cartridges according to requirements to reduce equipment costs and improve a drug tablet production efficiency. Related Art With the rapid development of science and technology, the production method of pills or drug tablets has changed from the traditional method of making through molds to the combination of 3D printing technology to print and manufacture the required drug tablets. With computer-aided 3D printing technology, ordinary drug tablets are manufactured by stacking layers of drug powder in 3D printing. Since in the existing 3D printing equipment used to print drug tablets, the drug powder must be placed in the powder collecting box, and the powder collecting box is combined with the printing equipment provided with nozzles, the powder collecting box and the printing equipment operate synchronously during processes of powder-dispensing and printing, especially during the printing process. In order to meet the requirements of printing, the printing equipment moves at a fast speed; in order to store a large amount of drug powder in the printing equipment currently available on the market, the powder collection box of the printing equipment needs to have enough powder storage space to store a large amount of drug powder, and therefore the volume of the powder collecting box needs to be large, and the weight of the powder collecting box becomes heavier, which lead to slower moving speed of the printing equipment, and poor yield of drug tablets. Furthermore, many existing drug tablets are composed of compound ingredients, so more powder collecting boxes need to be installed to accommodate drug powder of different compositions. Therefore, the printing equipment currently available on the market needs to be provided with a large number of powder collecting boxes for drug tablets composed of compound ingredients, which will relatively increase the manufacturing cost of the printing equipment, and the powder collecting boxes cannot be replaced or disassembled to match with different types of drug powder, which lead to slower moving speed of the printing equipment, and empty powder collecting boxes. Document WO 2020/145898 A1 relates to a three-dimensional (3D) printing node for manufacturing a personalized pill. Therefore, the inventor of the invention and relevant manufacturers engaged in this industry are eager to research and make improvement to solve the above-mentioned problems and drawbacks in the prior art. SUMMARY OF THE INVENTION Therefore, in order to effectively solve the above-mentioned problems, a main object of the invention is to provide a modular drug tablet manufacturing system capable of quickly replenishing drug powder and disposing drug powder cartridges according to requirements to reduce equipment costs and improve a drug tablet production efficiency. Another object of the invention is to provide a modular drug tablet manufacturing system capable of effectively separating different types of drug powder for printing to prevent the different types of drug powder from mixing with one another to affect effects of drug tablets. In order to achieve the above objects, the invention provides a modular drug tablet manufacturing system comprising a machine body, the machine body is provided with at least one assembling plate; and a plurality of powder-dispensing cartridges, the powder-dispensing cartridges are assembled with the assembling plate, a powder-dispensing accommodation space is formed in each of the powder-dispensing cartridges, and a powder-dispensing port is formed at a bottom of each of the powder-dispensing cartridges.
