Application and Development of Pneumatic Technique in Food Packaging Machinery

China's food packaging machinery has formed a certain scale after nearly 20 years development and become an important part of machinery industry. At present, China has put more effort on implementing the food quality and safety market access system; food packaging equipments are also being incorporated into this system gradually. Modern food packaging machinery is a collection of advanced technology from various subjects, and it is developing toward intelligentization and integration with features of high efficiency, high accuracy, high automation and high flexibility, one of the basic components is the pneumatic technique.

Pneumatic technique is one of the effective means for automatization and mechanization of production process, which has been widely used in light industry machinery with advantages of high speed and high efficiency, cleanness and safety, low cost and easy maintenance and so on, and it is playing more and more important role in the process of food packaging and hex bolt production. It can shorten assistant time in processing, reduce worker's labor intensity and fully develop high efficiency of equipments, so it is also be widely used in various packaging machinery. But food packaging machinery must be in line with related requirements and regulations of food machinery safety, and usually the environment of work scene is more complex and rigorous, so if use an inappropriate pneumatic components, it will lead to unusual phenomenon. However, modern food packaging machinery generally contains a combination of slitting machine, electricity, hydraulic pressure, pneumatic and other techniques, and the relation between these various parts is inseparable, because something wrong with any part of them will effect the normal work of the equipment.

In food area and splash area, the pneumatic technique is mainly used for devices such as pvc fitting distribution, bottling, forming, filling, dispensing, sealing and so on. Because pneumatic components need to contact production plastic valve material directly or indirectly, so the material should be non-toxic, non-absorbent, anti-corrosion and original stainless steel in order to avoid the pollution on end cip products. If use the aluminum alloy material, it should have certain corrosion resistance and should be non-toxic, non-absorbent. The rubber blow molding machine products used in the inner of components such as seals should accord with relevant health requirements, which should have heat resistant, acid and alkali resistance, oil resistance and other features, and also can accept normal cleanout and antisepsis. Typical pneumatic products used in the two environments have stainless steel pneumatic cylinder, clean-type cylinder, easy cleaning valve island, stainless steel filter, reducing valve and so on, of which the most representative is the clean-type cylinder.

In non-food area, the pneumatic bag making machine technique is mainly used for sealing bags, packaging, labeling, testing, stamping and other devices, although it doesn't need to contact production material in this area, but it still needs characteristics of standardization, easy cleaning, intelligentization, environment protection and so on. Because today's food packaging machinery is required to achieve more functions within limited space, so its size requirements also become more and more strict. In addition, the advanced food packaging equipments generally use lubrication-free pneumatic system that composed of filter, reducing valve and non-oil lubricating valve and cylinder. The system can seal lubricating grease into where the components need to lubricate without using atomized lubricator, work for a long time without adding lubricating grease, reduce fuel consumption and cost and improve construction machinery environment, at the time it is convenient to maintain and the performance is stable.

With the food processing technique increasing gradually, the automation level of food packaging is also growing continuously. At present, the research and development of food packaging machinery is developing in the direction of high speed, multifunction and intellectualized control, many technologies will be widely used such as industrial robotics, blow molding machine microelectronics, computers, intelligence type and image sensor, and the intelligentization and integration of pneumatic technique that used in food packaging machinery will also become inevitable. Intelligent pneumatic construction machinery trinity parts can make the self-diagnosis of air handling system possible, the majority of pneumatic system failure due to air handling system, but the intelligent trinity parts is valid to solve this problem, besides it can tell people when to replace filter or lubricating oil, whether the pressure condition is normal and record the use of time. Thereby it can decrease the failure rate to the lowest, reduce maintenance and repair costs, improve uptime and production capacity.

The exploitation and application of the intellectualized and networked pneumatic technique will promote food packaging machinery to further intelligentize and achieve the self-diagnosis of equipments, and then improve the automation level of domestic food packaging machines.
