Abstract: Seedling transplanting using paper chain pots is an efficient and sustainable crop cultivation technique originating from Japan, which has the advantages of reducing environmental impact, simple transplantation, and improving seedling survival rate. Compared with traditional cultivation techniques, it has the advantages of stronger seedling root systems and significant yield effects, which have significance for promoting multiple crop cultivations, improving land replanting index, increasing crop yield, and developing high-yield and efficient agriculture. However, the deficiency of technology and equipment for making paper chain pot in China and dependency of imports have limited the wider application of this technology on small and medium-sized farms. This study focuses on designing a technology and machine to automatically fabricate a type of paper chain pot nursery booklet, which integrates key processes such as gluing, indentation, paper feeding and folding, meeting the agronomic needs of transplanting seedlings in various crops and providing a cost-effective solution for domestic production. To start with, on the basis of explaining the principle of making a hexagonal cross-section bowl chain seedling booklet, a prototype of paper chain pot nursery booklet making machine was designed by using a combination of motors and pneumatics to drive the coordinated action of various working components, which can automatically achieve the formation and assembly of chain pots into booklets, significantly reducing manual labor and production costs. Relevant structural parameters were determined through the design and analysis of key components such as the glue coating device, which ensures precise adhesive application; the indentation device, which creates the necessary indentation for folding and formation; the paper feeding device, which drives the movement of the paper through the machine; and the folding paper collection device, which assembles the chain pots into a booklet format. In addition, an automated operation control system with functions such as one-touch start/stop, commissioning, cleaning and operating instructions was designed, using an STM32 microcontroller as the control core to coordinate the movement of all components, ensuring that each device in the production process occurs and the correct program. The working performance tests were carried out based on the prototype of the paper chain pot nursery booklet making machine using water-soluble adhesive, water-resistant adhesive and nursery paper. The paper feeding accuracy remains at a low level at different candidate job speeds, with a slip rate below 0.23%. The complete working test of making booklet results show that when the working efficiency is 60 copies/hour and the chain bowl length is between 12.16 and 21.28 m, the average pass rate is 91.55%. The seedling experiment results using oilseed rape and tomato showed that the germination rate of seedlings using the made paper chain pot nursery booklet is 96.21%, and the seedlings grow well. The paper chain pot nursery booklet can be easily dragged and unfolded into chains before transplanting, satisfying the requirements of seedling cultivation and lightweight automatic transplantation. The work performance indicators meet the requirements of the paper chain pot nursery booklet making, effectively saving manual labor, reducing production costs, and improving work efficiency. This research can provide new ways for realizing the development of the direction of intensification, scale and facilities in the nursery process and the direction of mechanization and automation in the transplanting process.
