Last Friday, Director Chen of a nut processing factory in Guangdong sent us a video - the old master in the workshop held the newly installed weighing and packaging machine and said: "I have been doing packaging for 20 years, and this is the first time I have seen such a 'serious' equipment!" In the picture, the pecan kernels are like queuing for security inspection. The weight of each bag is exactly the same, and even the debris is automatically screened into the recycling port. This scene made Lao Zhang of our R&D team happy: "The three months we fought with the electronic scale were worth it!"
Speaking of which, our factory has been fighting with "weighing" for a long time. Last fall, Mr. Liu from a condiment factory in the southwest came to inspect and said bluntly: "The weighing and packaging machines on the market either miss the scale or get stuck when dealing with light materials such as pepper and chili powder." This made us feel very embarrassed. When we returned to the workshop, we disassembled the test machine and found that the traditional gravity sensing module was indeed easy to "get confused" when encountering powdery materials. Later, we added a micro-vibration device to the feeding port, and now even 5 grams of thirteen spices can be steadily bagged.
This year's new model has another unique skill - it will not "get angry" on rainy days. The day when the Fujian customer tested the machine was in the plum rain season, the humidity in the workshop soared to 85%, and our weighing and packaging machine operated as usual. The secret lies in the inconspicuous moisture-proof box. The built-in drying module automatically ventilates every half an hour, and there is no need to worry about electronic components getting damp and causing measurement deviations. This small improvement can save customers who make kelp knots a lot of worry: "In the past, every time the south wind returned, the packaging error could be two or three percentage points different. Now we don't have to weigh it every day."
Automated production line integration is our main focus recently. The whole line transformation for a rice mill in Jiangsu last month is an example: from rice husking to vacuum packaging, 3 of our weighing and packaging machines were embedded in the 12 processes. What makes the workshop director most proud is that when switching between packaging bags of different specifications, the equipment can automatically identify and adjust the measurement parameters, eliminating the trouble of manual input. I heard that the 5-kilogram jasmine rice they export to the Middle East now has a stable pass rate of more than 98% for each batch of random inspections.
Colleagues in the maintenance department have also recently added new equipment - a portable calibrator. In the past, you had to bring half a box of weights to do annual maintenance for old customers. Now you only need to clamp the instrument to the weighing and packaging machine, and the accuracy calibration can be completed in five minutes. Mr. Zhou, who sells dried mushrooms in Zhejiang, joked: "You are forcing us to replace the machines. We are too embarrassed to have people come to maintain the old machines."
Standing in the shipping area and watching another batch of weighing and packaging machines being shipped to Xinjiang, I suddenly remembered the first semi-automatic model we built eight years ago. At that time, customers always complained that "one out of ten bags had to be reworked." Now, listening to the regular operation of the assembly line in the video, I can finally stand up straight and say: Our weighing and packaging machines are so serious that even we are afraid of them!
