When he received a call from Director Zhang in late autumn last year, he was so anxious that his voice became hoarse: "Our existing milk powder packaging machine always 'sneezes' at three or four in the morning - either metering deviation or loose sealing!" Only after a field investigation did he find that their old equipment had a metering error of up to three times the industry average during periods of large temperature and humidity fluctuations.
Installation site: 30 seconds of life and death
"Is this asking us to embroider in the milk powder cans!" Technician Xiao Wang stared at the slogan on the wall of the customer's workshop in a daze - "Error over 1 gram = harm to millions of families". It turned out that the company adopted the EU dairy product standard, requiring that the measurement error of each can of milk powder must be controlled within ±1.5 grams.
We transferred the latest milk powder packaging machine overnight. The installation team leader Lao Chen kept muttering while debugging: "The double spiral weighing scale must be recalibrated, just like installing an eight-fold scope on a sniper rifle." At two o'clock in the morning, when the first can of milk powder stopped steadily on the 800-gram scale, the quality inspector suddenly applauded-at this moment, I knew that the order was successful.
"Hello, ply-pack customer service department, how is the equipment running?"
"I was just looking for you!" The other party's tone was pleasantly surprised, "This milk powder packaging machine has made a contribution today! After the production line suddenly lost power and restarted, the measurement data actually automatically compensated for the temperature change value!"
This is the "environmental perception system" that we are proud of. It's like installing a "biological clock" for the milk powder packaging machine, which can automatically correct the measurement parameters according to the changes in temperature and humidity in the workshop. I heard that the company cut off the original manual sampling once an hour because of this, and now the quality inspectors are laughing and saying that they are about to be "unemployed".
We received an urgent repair report from a dairy company: the aluminum film seal of the milk powder packaging machine had slight wrinkles.
When we arrived at the scene, we found that the problem was with the environmentally friendly packaging film newly purchased by the customer - this degradable material is 30% softer than conventional film. We immediately launched Plan B:
. Replace the buffer gasket of the heat sealing module
. Adjust the sealing pressure from 25N to 18N
. Add a real-time monitoring function for film material tension
Watching the equipment spit out a smooth seal like a mirror again, the workshop director Lao Li clapped his legs and exclaimed: "You have done a 'micro-plastic surgery' on the machine!"
Invisible Guardian
At the acceptance meeting, I especially demonstrated the "hidden skills" of the milk powder packaging machine: when a metal foreign body is detected, the equipment will immediately lock the current batch of products. Director Zhang stared at the red alarm light that suddenly lit up and sighed: "This protection system is more sensitive than the inspection room we spent millions to build!"
The return visit three months later is still fresh in my memory. The company's technical director pointed to the data stream on the monitoring screen and said: "Since using your milk powder packaging machine, the product loss rate has dropped to 1/3 of the industry average. In particular, the moisture-proof packaging solution has reduced the number of complaints about high-calcium milk powder agglomeration to zero."
When leaving the factory, I saw a photo of our equipment on the honor roll of the workshop, with a line of handwritten words underneath: "Silent Quality Inspector". This may be the best compliment to the milk powder packaging machine - it can't speak, but with thousands of precise movements, it protects every family's peace of mind.
