In modern pharmaceutical production, it mainly includes three basic links, namely raw material processing, medium processing and pharmaceutical packaging. Packaging is a very important part of production. Pharmaceutical packaging machinery is the fundamental guarantee for mechanization and automation of pharmaceutical packaging. Therefore, packaging machinery plays an important role in the modern industrial production of medicine.

    (1) The pharmaceutical packaging machinery has realized the specialization of pharmaceutical packaging production and greatly improved production efficiency.

    (2) Mechanization of pharmaceutical packaging reduces labor intensity, changes labor conditions, protects the environment, saves raw materials, and reduces product costs. When packaging liquid products by hand, it is easy to cause splashing of the product; when packaging powdery products, it often causes dust to fly, which pollutes the environment and wastes raw materials. The use of mechanical packaging can prevent the loss of products, which not only protects the environment, but also saves raw materials.

    (3) To ensure the hygiene and safety of packaged drugs, improve the quality of pharmaceutical packaging, and enhance the competitiveness of market sales. drug

The hygiene and safety requirements are very strict, using mechanical packaging, avoiding direct contact between human hands and drugs, and reducing pollution of drugs. At the same time, due to the fast speed of mechanical packaging, the drug stays in the air for a short time, which reduces the chance of pollution and is conducive to the hygiene and safety of the drug.

    (4) Extend the shelf life of the drug to facilitate the circulation of the drug. The use of vacuum, ventilation, aseptic packaging machines, etc., can make the circulation of drugs more extensive and extend the shelf life of drugs.

    (5) The use of packaging machines for medicines can reduce the area of packaging space and save infrastructure investment. When the medicines are hand-packed, the packaging operation is large and the infrastructure investment is large because there are many packaging workers and the process is not compact. With mechanical packaging, the supply of medicines and packaging materials is relatively concentrated. The packaging process is relatively compact, reducing the footprint of the packaging and saving infrastructure investment.

    Pharmaceutical packaging machinery not only has the commonality of general automatic machinery, but also has its own characteristics.

    (1) Most packaging machines are complex in structure, fast in motion and high in motion accuracy. In order to meet the performance requirements, the rigidity and surface quality of the components are highly demanded.

    (2) The packaging machine used for medicine should be easy to clean, and the parts in contact with medicines and food should be made of stainless steel or chemically treated non-toxic materials. Meet the hygiene requirements of the drug.

    (3) The working force of the packaging actuator is generally small, so the motor power of the packaging machine is small.

    (4) The packaging machine generally adopts a stepless speed change device to flexibly adjust the packaging speed and adjust the production capacity of the packaging machine. Because there are many factors that affect the quality of the packaging, such as the working state of the packaging machine (the state of motion of the mechanism, the temperature of the working environment, humidity, etc.), the quality of the packaging materials and packaging, and so on. Therefore, in order to facilitate the adjustment of the machine and meet the needs of quality and production capacity, most of the packaging machines use a continuously variable transmission.

    (5) Packaging machinery is a special type of professional machinery with a wide variety and limited production. In order to facilitate manufacturing and maintenance, reduce equipment investment, attention should be paid to standardization, versatility and versatility in the design of packaging machines.

    (6) The pharmaceutical packaging machinery must meet the requirements of the GMP certification of the drug to ensure the safety of the drug.

    (7) The degree of automation of pharmaceutical packaging machinery is high, and some have been controlled by PLC and single-chip microcomputer, which has realized intelligence.
