Recently, the new intern Xiao Liu in the workshop always pestered me and asked: "Mr. Zhang, what are the unique skills of our automatic packaging machine for groceries?" This is the right person to ask! As the technical director who has been following the upgrade of this equipment for three generations, I know the ins and outs of it too well. From grains to nuts and dried goods, to seasonings of various shapes, it is not enough to rely on a few sensors to make the machine sort and package as flexibly as human hands. Last year, when we were renovating the production line for a grain factory in Hebei, their workshop director Lao Zhao was still wondering: "Can the machine distinguish between black beans and black rice?" Guess what happened? Our automatic packaging machine for groceries relies on a high-precision visual recognition system to sort the mixed grains clearly. The secret lies in the self-developed dynamic compensation technology - the machine can sense the state of the material in real time, like installing a "corrector" for the packaging action. Even if it encounters uneven cashews or sticky red dates, it can still grab them accurately.
The most proud technological breakthrough is the "variable adaptability" of the material. Last month, a customer in Yunnan sent a box of wild mushrooms of various shapes, saying that they wanted to test the extreme performance of the equipment. The guys in the workshop adjusted the parameters overnight and made the machine sort the porcini mushrooms with a difference of 3 cm in cap diameter into three levels of packaging. This material adaptability is not exaggerated. We have specially developed a flexible gripping module, which can hold everything from fragile hollow noodles to slippery scallops.
You may not know that the "heart" of the automatic packaging machine for groceries is the industrial-grade transmission system. Mr. Wang, an old customer in Northeast China, often said: "Your machine works in a warehouse at minus ten degrees, and it is more energetic than our workers in cotton-padded jackets!" This is all thanks to the triple seal design and anti-low temperature lubricating oil in the transmission box. Last year's Double Eleven, the machine in an e-commerce warehouse in Zhejiang ran continuously for 36 hours, and the packaging yield rate remained above 99%. The customer later sent a special banner.
Xiao Li from the technical department has been saying recently: "Now customers' requirements are getting more and more tricky." Last week, a seafood processing factory in Shandong proposed to package mixed seafood dry goods bags of different weights. We loaded the intelligent formula mode into the automatic packaging machine for groceries overnight. Now, as long as you select the matching plan on the touch screen, the machine can automatically complete weighing, proportioning, and bagging. When the customer accepted the product, he slapped his thigh and said, "This is like giving the packaging line a brain!"
In fact, the most challenging part for technology is the details. For example, in the sealing process of the packaging bag, traditional heat sealing is prone to cracking when encountering grains with fluctuating moisture content. Our engineers got inspiration from the sealing ring of the pressure cooker and developed an air pressure adaptive sealing device. Now, whether it is freshly dried wolfberries or damp raisins, the sealing line can be as smooth as a knife cut. Customers in Jiangsu reported that after using our equipment, the supermarket return rate was directly cut in half, and the shelf life was extended by 20 days.
Recently, we are also adding the "cloud diagnosis" function to the automatic packaging machine for food and groceries. You may not think that Mr. Huang in Guangdong solved the problem of abnormal noise of the equipment through the mobile phone APP last week-it turned out that the new employee did not clean up the debris in time. This kind of 24-hour online technical support is the real confidence for customers to let go and upgrade automation.
Looking at the fifth-generation prototype being assembled in the workshop, I often tell my apprentices: "To engage in technology, you have to feel the pulse like an old Chinese doctor, and you have to understand the pain points of each customer." From solving sorting errors to improving packaging yields, from overcoming extreme working conditions to achieving flexible production, our factory's automatic packaging machines for groceries rely not on fancy gimmicks, but on real technical accumulation. After all, making customers' production lines run more smoothly and with lower losses is the most impressive achievement for us technicians!
