[0002] Potash fertilizer, also known as potassium fertilizer, is a fertilizer with potassium as the main nutrient. After the finished product is processed, it is packed into fertilizer bags and sewn by a bag sewing machine. At present, bags filled with fertilizers need to be manually supported at the opening and tightened by a bag sewing machine to achieve packaging. However, during the sewing process, workers need to move synchronously with the fertilizer bags on the conveyor belt. Frequent movement increases labor intensity and increases the processing time of a single fertilizer bag, reducing production efficiency. In addition, there are certain operational risks during the sewing process, which is not conducive to production and processing. Utility Model Content
