In the nano-carbon powder packaging workshop, operator Liu Wei had to manually calibrate the equipment more than ten times a day - ultrafine powders are very easy to hang on the wall in the traditional weighing system, resulting in a 3%-5% weight deviation for each batch of products. This industry-wide problem is now completely ended by ply-pack's electromagnetic suspension metering bin.
The core technology breakthrough comes from the change in the way materials contact. The R&D team abandoned the traditional mechanical tray structure and creatively introduced electromagnetic suspension technology to keep the loading bin suspended in a closed cavity. When powder with a particle size of less than 20μm enters the metering area, the AI vision system automatically identifies the material distribution state and adjusts the electromagnetic field strength of the suspension bin in real time to ensure that the powder passes through the metering sensor in a uniform laminar form.
"The correction speed of this dynamic weighing system is 120 times faster than manual work." During the on-site demonstration at the customer site, the technical director grabbed a handful of talcum powder and sprinkled it on the running equipment. The data curve on the monitoring screen fluctuated for only 0.05 seconds and then returned to a stable state. This anti-interference ability enables even graphene, metal powder and other easily floating materials to achieve a packaging accuracy of ±0.1 grams.
The actual application data of food enterprise customers is more convincing. After using this solution, a certain infant formula manufacturer cancelled the weight re-inspection station on the production line, which alone saved 450,000 yuan in labor costs each year. More importantly, the self-cleaning design of the suspension bin allows the equipment to avoid the risk of cross-contamination when switching lactose and probiotic powder.
