The origin of packaging machine
Chinese packaging machinery started in 1970s.
China's 1st packaging machines are imitated by Beijing Commercial Machinery Research Institute after studying Japanese products.
After more than 20 years, 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 and basically meeting the needs of the domestic market, some high-quality products are exported overseas.
However, at this stage, the export value of China's packaging machinery is less than 5% of the total output value, while the import value is roughly equivalent to the total output value, and there is still a big gap compared with developed countries.
The level of China's packaging machinery industry is not high enough. Except for some small packaging machines with a certain scale, other packaging machinery is almost fragmented, especially the liquid filling production line, aseptic packaging production line, etc, almost monopolized by several foreign packaging giants.
But worldwide, the global demand for packaging machinery is at 5. 5% per year.
The speed of 3% is growing rapidly, mainly in the United States, Germany, Italy and Japan.
However, with the growth of packaging demand, the growth rate of packaging machine production in developing countries will be faster in the future.
China's packaging machinery, in the joint efforts of generations of packaging robots, explores progress and makes great progress.
China's packaging machinery will also become the main force in China's machinery trade in the future.
Pillow packing machine
pillow packing machine is a relatively new type of automatic continuous shrink packaging equipment in China at present. It is characterized by fast temperature rise, good stability, low maintenance cost, stable and adjustable shrink temperature and motor transmission speed, and the adjustment range is wide; The roller rotation device can work continuously.
Therefore, the Heat Shrinkable machine has the characteristics of advanced design, stability and reliability, high power saving efficiency, good shrinkage effect, beautiful structure, convenient operation and maintenance, etc.
The working principle of pillow packing machine pillow packing machine is a kind of continuous packing machine with very strong packaging capacity and suitable for various specifications for food and non-food packaging.
It can be used not only for packaging of non-trademark packaging materials, but also for high-speed packaging using drum materials with pre-printed trademark patterns.
In the packaging production, due to the errors between the positioning color codes printed on the packaging materials, the stretching of the packaging materials, mechanical transmission and other factors, the predetermined sealing and cutting position on the packaging material may deviate from the correct position, resulting in errors.
In order to eliminate errors and achieve the purpose of correct sealing and cutting, the problem of automatic positioning must be considered in packaging design. To solve this problem, most of them are to complete the design of continuous photoelectric automatic positioning system according to the positioning standard of packaging materials.
However, the continuous photoelectric positioning system is divided into advance and retreat type, braking type and synchronous type of two transmission systems according to the error compensation working mode.
The structural characteristics of pillow packaging machine 1. Double frequency converter control, the bag length is set and cut immediately, no need to adjust the empty walk, one step in place, saving time and film.
2. Text-based man-machine interface, convenient and fast parameter setting.
3, fault self-diagnosis function, fault display at a glance.
4. High-sensitivity photoelectric eye color code tracking makes the sealing and cutting position more accurate.
5. Temperature independent PID control is better suitable for coating of various materials.
6, positioning shutdown function, no sticking knife, no film.
7. The transmission system is simple, the work is more reliable, and the maintenance is more convenient.
8. All controls are realized by software, which is convenient for function adjustment and technology upgrade and will never fall behind.
