[China Packaging Network News] China's packaging machinery started relatively late. In the 70s of the last century, the Beijing Institute of Commercial Machinery completed the manufacture of the first packaging machine in China after researching Japanese packaging machinery. After more than 20 years Development, China's packaging machinery has become one of the top ten industries in the machinery industry, providing a strong guarantee for the rapid development of China's packaging industry, some packaging machinery to fill the gaps in the domestic market, has been able to basically meet the needs of the domestic market, some products have exports . However, at this stage, the export value of China's packaging machinery is still less than 5% of the total output value, but the import value is about the same as the total output value, which is far from the developed countries.
In spite of this, pillow packing machines that have emerged in the packaging machinery industry have been on the way to progress.
Pillow type packaging machine is the latest type of automatic continuous shrink packaging equipment in China. It uses quartz far-infrared tube heating, energy saving and high efficiency (saving more than 15% of electricity). The shrinking temperature and motor transmission speed are stable and adjustable, and the adjustment range is wide; Roller rotation device can work continuously. Therefore, the thermal shrinking machine has advanced design, stable and reliable performance, energy-saving efficiency, good shrinkage effect, novel and beautiful structure, convenient operation and maintenance, and can be applied to any shrink film shrink packaging. Better performance than previous shrink machines, better packaging and ease of use.
It is a continuous packaging machine that has a very strong packaging capacity and is suitable for a variety of specifications for food and non-food packaging. Not only can it be used for packaging of unbranded packaging materials, but it can also be used for high-speed packaging using roll materials pre-printed with logo designs. In the packaging production, due to the errors between the positioning color patches printed on the packaging materials, the stretching of the packaging materials and the influence of mechanical transmission, the predetermined sealing and cutting position on the packaging material may deviate from the correct position, resulting in an error. In order to eliminate the error and achieve the purpose of correct sealing, packaging design must consider the problem of automatic positioning. To solve this problem, the continuous photoelectric automatic positioning system design is mostly based on the positioning standard of packaging materials. The continuous photoelectric positioning system is divided into forward and backward type, brake type, and two-transmission system synchronization type according to the error compensation working mode.
In the rapid development of the industry, there are also a series of problems. At this stage, the level of China's packaging machinery industry is still not high enough. The packaging machinery market is becoming more and more monopolized. Except for corrugated paper box packaging machinery and some small packaging machines, which have a certain scale and advantages, other packaging machinery are almost unsystematic and large-scale, especially in the market where some large-scale packaging production lines are needed, such as liquid filling. Production lines, complete sets of beverage packaging containers, aseptic packaging production lines, etc., are monopolized by several large packaging machinery enterprise groups in the world packaging machinery market, and positive measures should be taken in the face of the strong impact of foreign brands on domestic enterprises.
According to the editor of China Packaging Network, although there are still many loopholes in the packaging machinery market, it is believed that under the baptism of time, the packaging machinery will be able to correctly understand the deficiencies and strive to make up for these fragmented dimensions, and the pillow packaging machine will also be able to In the environment, it grows after hone.
