Last week, Lao Zhou made a joke when debugging the equipment-the new operator looked at the jumping curve on the PID control screen and said that this thing looked like a girlfriend's mood line chart. This reminded me that our packaging film tension constant pressure regulation technology is a good medicine for all kinds of "emotional fluctuations", isn't it?
The temper of packaging film is much more unpredictable than that of a girl. If the humidity in the workshop rises by two points, the film tension will change; if you are not careful when changing the roll, the whole line can give you a cold shoulder. Last year, when we renovated the instant noodle packaging line for a Zhejiang customer, their factory manager pointed at the packaging film that was wrinkled like an accordion and sucked his teeth: "If this film was a person, it should have been sent to psychological counseling long ago!"
Our technical department has been holding back for three months and finally found a breakthrough in PID algorithm control. Don't be fooled by this foreign term. To put it bluntly, it is to install a "smart seat belt" for the packaging film. When ordinary equipment encounters sudden tension changes, it is like a novice stepping on the brakes, either too hard or too soft. Our constant pressure regulation system is like an old driver with 30 years of driving experience. It can predict the "little emotions" of the film 0.5 seconds in advance and suppress the fluctuations in the bud through three-way closed-loop feedback.
Last month, a South African customer came to inspect the goods and insisted on testing the machine with an ultra-thin cling film of 0.008mm. This film is more delicate than a cicada's wing. It can be torn even if you take a breath when passing the roller. When we start the PID algorithm control program, the tension curve is so stable that it can make electrocardiogram doctors unemployed. The customer's technical director held a magnifying glass and searched for ten minutes, but he couldn't find the legendary "stress lines". He immediately placed an order for 20 machines.
What makes us even more proud is the "adaptive" ability of this system. Do you know how difficult it is to handle packaging films of different materials? PE film is like a slippery loach, and aluminum foil film is as stubborn as a donkey. We have buried more than 50 material parameters in the PID algorithm. Now, whether it is a corn starch film that softens when heated or a composite film that becomes brittle at low temperatures, the equipment will "taste" the material properties and automatically match the optimal pressure curve.
A few days ago, I received a video from a customer in Inner Mongolia. Their potato chip packaging line was running happily in a warehouse at minus 15 degrees. In the picture, the packaging film was stretched as if it had been ironed, and was not affected by the temperature difference at all. You know, in this environment before, the frozen and cracked film rolls alone could turn the workshop into an ice rink. The customer's boss was happy on the phone: "Your PID algorithm is more reliable than the lasso on the grassland!" From the laboratory to the production line, this packaging film tension constant pressure regulation technology has overcome nine technical difficulties. Next time if you encounter the trouble of film wrinkling and deviation, don't rush to change the film, come to our workshop first to see how these "film masters" use PID algorithms to perform magic. Make sure your packaging film is as obedient as if it has been through military training, horizontal and vertical without breathing!
