A brief analysis of the gap between domestic and foreign packaging machinery

in terms of the overlap of the adjacent ranges of automatic control technology, foreign pharmaceutical packaging machinery and equipment have basically achieved intelligent and humanized design, while China's pharmaceutical packaging machinery is relatively backward in PLC control and interface control. In addition to using PLC control technology, we must make supporting choices in materials, design and all related links at the same time, so as to realize intelligent control. The stability of China's pharmaceutical packaging machinery is still relatively poor, which may lead to problems in product quality and affect the whole packaging line

the outstanding stability of pharmaceutical packaging machinery is a key requirement for pharmaceutical manufacturing enterprises with large production capacity and a wide range of products, because unstable equipment is easy to lead to shutdown and disconnection and affect production. The main factors affecting the stability of pharmaceutical packaging machinery are materials, components and basic transmission devices. First, the low-level configuration of materials and components will seriously affect the stability of equipment, but at present, some enterprises in China purchase low-grade or even inferior materials and components for cost considerations; Second, the basic transmission device on the packaging machine is also one of the factors affecting the stability of packaging machinery

at present, China's pharmaceutical packaging equipment is basically based on basic transmission devices such as chains, tugs, and swinging stems, which will bring hidden dangers to the stability of machinery, while foreign pharmaceutical packaging machinery basically adopts servo drive systems. It should be said that it is not very difficult for enterprises to choose a servo motor, but enterprises usually consider the potential cost pressure of introducing servo motors. Enterprises have changed from the traditional transmission mode to the application of servo motors, and then need to provide servo motors for other institutions or equipment. In this way, with the improvement of control accuracy, the cost also increases, so that many medical students should immediately stop using the experimental machine, and the manufacturing enterprises are unable to afford it

take the aluminum-plastic packaging machine as an example, the domestic aluminum-plastic packaging machine in China lags far behind that in foreign countries, reflecting each specific work link. For example, the lines of aluminum-plastic packaging machines produced in China are deep and uneven. For another example, the feeding process is a very critical and weak link in all types of packaging machines at home and abroad, but compared with foreign countries, the feeding process of pharmaceutical packaging machines in China is even weaker. China also has roller brush aluminum plastic packaging machine, which adopts special feeding process. In terms of the production capacity of the feeding process, taking capsules as an example, the output of domestic equipment is 600 tablets per minute, and that of tablets is 700-800 tablets per minute, while the feeding process of foreign aluminum-plastic packaging machines can achieve a production speed of 2000 tablets/minute. The production speed and operation status of the aluminum plastic packaging machine are directly affected by the materials used, processing means and supporting coordination of the mechanism

it is not enough for the packaging machinery industry to only recognize the gap, but also to take actions to constantly narrow the gap. This requires the industry to develop from the depth of GMP certification and strive to make up for its own shortcomings
