Standing in the debugging area on the second floor of the general assembly workshop, I watched the technical team making the final calibration for the third-generation Chinese automatic packaging machine to be exported. The unique soft humming sound when the equipment is running reminds me of the scene when I first participated in the transformation of the old mechanical cam packaging machine ten years ago-who would have thought at that time that our intelligent correction system can now stably control the packaging accuracy at the millimeter level?
Servo drive technology breaks the game
Our factory has been betting on servo drive technology since 2015, when pneumatic positioning devices were still widely used in the industry. I remember when I was upgrading the equipment for a milk powder company, their engineer stared at our Chinese automatic packaging machine and asked: "Can these servo motors really withstand 24-hour continuous operation?" Now the answer has been written into the production log of the customer's workshop: after adopting the full servo solution, the comprehensive energy consumption of the equipment is reduced by nearly 30% compared with the traditional model, and this data is particularly evident in the chemical raw material packaging line.
The actual test of intelligent deviation correction
The pet food packaging project completed last month is a classic example of the intelligent deviation correction system. The packaging machine originally used by the customer often caused poor sealing due to the deviation of the film material. Our engineers installed a dual visual inspection module on the equipment. Now when the equipment is running, it is like installing an "adaptive nerve" on the Chinese automatic packaging machine, which can not only correct the deviation within 0.5 mm in real time, but also autonomously learn the shrinkage characteristics of different film materials. Lao Zhou, the person in charge of the customer site, joked: "This machine is more sharp than our master's eyesight."
The evolution of modular design
After working in the technical department for ten years, what I admire most is the modular design concept of our factory. The rotary packaging unit developed for the daily chemical industry last year was directly used in the automated production line of pesticide granules after adjustment this year. This "building block" technology route allows Chinese automatic packaging machines to quickly adapt to the needs of different industries. The auto parts company I visited last week said with emotion: "Your multi-axis collaborative control system can handle the anti-sticking packaging of rubber parts and the anti-rust packaging of metal parts at the same time, which completely subverts our understanding of domestic equipment."
Technical breakthrough at three o'clock in the morning
Speaking of technological breakthroughs, we have to mention the tough battle last winter. A chocolate packaging line exported to Southeast Asia suddenly encountered a molten slurry adhesion problem. At that time, my colleagues in the R&D team and I were stationed in the workshop for 72 hours in a row. Finally, by adjusting the temperature curve algorithm of the heat sealing knife and coordinating with multi-axis collaborative control technology, Chinese automatic packaging machines can also operate stably in high temperature and high humidity environments. When the first batch of perfectly sealed chocolate blocks came off the line smoothly, the Malaysian customer gave a thumbs up and said "incredible" three times.
Technical reserves for the future
In the laboratory's confidential project library, there are more exciting black technologies. The quantum sensing technology we are testing is expected to improve the accuracy of packaging detection to the micron level. Although the technical director, Mr. Zhang, reminds us not to be too ambitious, everyone knows that it is this kind of perseverance in core technology that has allowed our factory's Chinese automatic packaging machines to frequently win orders at international exhibitions.
Every time I walk through the workshop corridor and look at the slogan "Technology Establishes the Factory" on the wall, I feel that the responsibility on my shoulders is a little heavier. From catching up with imported brands to setting industry standards, the evolution of China's automatic packaging machines is the growth history of our technical people. In the future, we will continue to gnaw on the hardest "technical bones" and use tangible innovative achievements to write a new footnote for "China's Intelligent Manufacturing".
