At the beginning of last spring, Mr. Wang, an old customer from Heilongjiang, came to the factory in the heavy snow. He slammed the table as soon as he entered the door: "If you can handle my three old packaging lines, I will take care of all the fish in the river this year!" Their factory makes mixed fertilizers. Every rainy season, there are always customers complaining about caking. When they open the packaging bags, they find that the fertilizer is so hard that it can be used as bricks to build walls. We remembered this incident - three months later, when the first automatic packaging line for large bags of fertilizer was running in their workshop, Mr. Wang kept saying while touching the dryness tester: "If I had met you ten years earlier, I could have bought a fishing boat with the compensation I saved!"
Moisture-proofing requires efforts from the inside out
Those who have worked in agricultural supplies know that the automatic packaging line for large bags of fertilizer is most afraid of "moisture inside and outside". Ordinary packaging lines are prone to bring in moisture when sealing. When encountering a warehouse in the northeast with a temperature of minus 20 degrees, water vapor condenses into ice chips in the bag, and when it melts, it becomes the culprit of agglomeration. We added double insurance to the packaging line: first, the cyclone dust removal system presses the humidity of the raw materials to the critical point, and then a nitrogen curtain is laid at the heat sealing station. You may not think that this trick was stolen from the nitrogen-filled packaging of potato chips. Now in the customer's workshop, the sealed ton bags can be directly stacked on the open-air platform waiting for loading. Last year, there were continuous rainy days during the autumn harvest season, but we did not receive a single complaint about moisture.
Dust control is more sophisticated than farming
At the beginning of the year, I went to a compound fertilizer factory in the northwest to debug equipment. The workshop director Lao Ma pointed to the dust on the windowsill and joked: "Our workers shake their clothes after get off work and can collect half a bag of fertilizer." This remark really stimulated us - we installed a "breathing filter" on the automatic packaging line for large bags of fertilizer when we came back. Negative pressure adsorption combined with water mist sedimentation, the dust collection rate directly soared to 98%. The most amazing thing is the recycling system, the collected dust is automatically mixed back into the raw material flow, and the customer's finance department slapped his thigh: "This trick alone can save the money of two pickup trucks from the air every year!"
For palletizing, machines understand "Tetris" better than people
The most headache for traditional ton bag packaging is palletizing. Workers have to drive forklifts to play "Stacking", and if they are not careful, it will be crooked like the Leaning Tower of Pisa. The intelligent palletizing robot arm we equipped for the packaging line has built-in 17 types of pallet type algorithms. Last month, a customer from Inner Mongolia sent a video: a robotic arm grabbed a ton bag and moved it around, creating a honeycomb structure on a 12-meter-long trailer, saving space to load eight more bags of goods. The boss of the transportation company exclaimed: "This skill is more tricky than my 20-year-old driver!"
Customer workshop has become a "technical test field"
To be honest, many improvements to the automatic packaging line for large bags of fertilizers were forced out by customers. Just like the factory manager Li in Hebei who loves to argue, he insisted that we add a shockproof design to the weighing module, saying that their factory is next to the railway, and the electronic scale "dances disco" every day when the train passes. Our engineers simply moved the building shock absorption technology. Now, even if the foundation is being laid next to the workshop, the weighing error does not exceed the weight of a bucket of water. Later, this design was written into the standard configuration, and the factory manager Li proudly sent a group text message: "We can also be regarded as falling on the side of the railway track - shaking out experience!"
Recently, "smart agriculture" has become popular in the industry. If you ask me, no matter how high-end the concept is, it must start with tying a bag of fertilizer. Just like the automatic packaging line for large bags of fertilizer in our factory, it may not talk about the Internet of Things and big data, but its intelligent temperature control system, self-cleaning conveyor belt, and touch screen that can remember 300 recipes are silently helping the agricultural material factory to ensure quality. Next time you pass by the Northeast Granary and see the ton bags with the "ply-pack" logo neatly stacked on the platform, you might as well get close and touch them - the bag mouth is sealed more tightly than the edge of a dumpling!
