The origin of the packaging machine

China's packaging machinery started in the 1970s. The first packaging machine in China was copied by Beijing Commercial Machinery Research Institute after studying Japanese products. After more than 20 years, Chinese packaging machinery has become one of the top ten industries in the machinery industry, which provides a strong guarantee for the rapid development of China's packaging industry. It can basically meet the needs of the domestic market, and some high-quality products are exported to overseas. However, at the present stage, China's packaging machinery exports are less than 5% of the total output value, but the amount of imports is roughly equal to the total output value, compared with developed countries there is a big gap.

The level of China's packaging machinery industry is not high enough. In addition to some small packaging machines with a certain scale, other packaging machinery is almost no system, especially liquid filling production lines, aseptic packaging production lines, which are almost monopolized by several foreign packaging giants.

But in terms of the world, the global demand for packaging machinery is growing at an annual rate of 5.3%, mainly in the United States, Germany, Italy, Japan. But with the growth of packaging demand, developing countries in the future packaging machine production growth will be the fastest. China's packaging machinery, in a generation of packaging machinery under the joint efforts, explore forward, rapid development. 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 the latest type of automatic continuous shrink packaging equipment in China. It is characterized by high temperature, good stability, low maintenance cost, stable and adjustable shrinkage temperature and motor transmission speed, and wide adjustment range. Roller rotation device, can work continuously. Therefore, the thermal shrinkage machine has the characteristics of advanced design, stable and reliable, efficient power saving, good shrinkage effect, beautiful structure, convenient operation and maintenance.

The working principle of pillow packing machine

Pillow packing machine is a kind of packaging capacity is very strong, and can be suitable for a variety of specifications for food and non-food packaging continuous packaging machine. It can not only be used for the packaging of non-trademark packaging materials, but also can use the pre-printed logo of the drum material for high-speed packaging. In the process of packaging production, due to the errors between the positioning color codes printed on packaging materials, the influence of stretching and mechanical transmission of packaging materials and other factors, the predetermined sealing and cutting parts of packaging materials may deviate from the correct position, resulting in errors. In order to eliminate errors and achieve the purpose of correct sealing and cutting, automatic positioning must be considered in packaging design. Most solutions to this problem are to complete the design of continuous photoelectric automatic positioning system according to the positioning mark of packaging materials. The continuous photoelectric positioning system can be divided into forward and backward type, brake type and synchronous type according to the error compensation mode.

Structural characteristics of pillow packing machine

1) Double frequency converter control, bag length is set and cut, no need to adjust the empty walk, one step in place, save time and save film.

2) Text man-machine interface, easy and quick parameter setting.

3) Fault self-diagnosis function, fault display at a glance.

4) High sensitivity photoelectric color label tracking, so that the sealing and cutting position is more accurate.

5) Temperature independent PID control, better suitable for all kinds of material envelope.

6) Positioning stop function, no stick knife, no film.

7) Simple transmission system, more reliable work, more convenient maintenance.

8) All controls are realized by software, convenient for function adjustment and technology upgrade, never lag behind.

Packaging machine selection guide

1. First of all, we should determine which products we will buy the packaging machine. Some packaging machinery manufacturers have many varieties of products, in the purchase of packaging machine, I hope that a device can package all kinds of their own. In fact, the special machine is often better than the integrated machine packaging effect. It is best not to pack more than 3-5 varieties of a packaging machine. Also, the size gap is relatively large products as far as possible separate machine packaging.

2. High cost performance is the first principle. At the present stage, the quality of domestic production of packaging machine has been greatly improved than before, especially pillow packaging machine, export proportion has been imported a lot, so the price of domestic machinery can completely buy the quality of imported machine. Only buy the right one, not the expensive one.

3, as far as possible to choose a long history of famous brand packaging machine enterprises, quality is guaranteed. Choose mature technology, stable quality models, make packaging faster and more stable, low energy consumption, low manual, low reject rate. Packaging machine is a consumption machine, if the purchase of low-quality machines, in the future of the daily production of accumulated waste of packaging film, the decision is not a small number.

4, if there is a field trip, we should pay attention to the big aspects, more attention to small details, often details determine the quality of the machine. Bring samples to test the machine as much as possible.

5. In terms of after-sales service, we should have a good reputation in the "circle". After-sales service is timely and on call, especially important for food processing enterprises. For example, mooncake enterprises only have a short production period of two months each year, if the packaging machine in the production of problems can not be solved immediately, the loss can be imagined.

6, the peer trust packaging machine can be preferred.

7, as far as possible to choose simple operation and maintenance, complete accessories, automatic continuous feeding mechanism, which can improve packaging efficiency and reduce labor costs, suitable for the long-term development of enterprises.

8. Find a professional custom design manufacturer. According to the product characteristics, packaging film material and site conditions customized design pipeline.

9. Select packaging machine manufacturers with perfect training constitution, and conduct systematic operation training for operators to improve production efficiency.
