The production line can be divided into automatic weighing unit, packaging and sewing unit, automatic bag supply unit, conveying and testing unit, palletizing unit (joint robot palletizing, high-position palletizer), etc. It is widely used in petrochemical, fertilizer, building materials, etc. , grain, port, logistics and other industries, realize the automation of the whole process of materials from the finished product out of the warehouse to weighing, packaging, testing and palletizing. Operation procedures such as automatic feeding, automatic bag feeding, bagging, weighing, bagging, heat sealing, conveying and shaping, weight detection, metal detection, inspection and screening, inkjet printing, automatic palletizing, etc. are completed in sequence. The entire production line is automatically controlled by intelligent programs, which can realize continuous operation, with fault alarm, display and automatic chain stop functions. It can also be equipped with a communication interface according to user needs to realize real-time monitoring and remote diagnosis of the automatic packaging and palletizing production line. and network management. It has the advantages of high work efficiency, advanced and reasonable structure, convenient operation and maintenance, and reliable performance. The production line is equipped with an advanced manipulator palletizer, which is a replacement product of the traditional palletizer. It has the advantages of small size, small footprint, low operating cost, large production capacity, higher work reliability, and simple program modification, which can adapt to the needs of various packaging bag specifications.1.
