There are many plant seeds, gymnosperms and angiosperms unique propagules, which are formed by ovules through pollination and fertilization. In particular, the seeds of crops have attracted attention. In 2017, the 'Administrative Measures for Crop Seed Labels and Instructions for Use' issued by the Ministry of Agriculture of the People’s Republic of China has been formally implemented. Since then, all crop seed packages must be marked with a QR code to help Seed companies quickly meet the two-dimensional codes required by the Ministry of Agriculture and meet the needs of batch production of seed traceability two-dimensional codes. The seed packaging identification inkjet printer and the traceability system are connected to each other, which can complete the whole process of code assignment during the packaging and printing process. The enterprise provides a full range of services. The seed packaging identification inkjet printer can be well applied in this industry. First, the inkjet printer has a communication protocol, that is, it can be connected to a computer, and the variable data content to be printed is transmitted to the inkjet printer through computer transmission, and the system automatically The printing is completed one by one; secondly, the seed inkjet printer is non-contact product surface for printing and marking, and the ink of the inkjet printer is environmentally friendly and quick-drying. At the same time, it is equipped with an LED UV curing lamp, which dries after spraying, so the product identification is greatly improved. Increase production efficiency and increase production capacity. The variable QR code printed by the seed packaging identification inkjet printer facilitates the traceability and tracking of product quality during the circulation and use of seeds. The inkjet printer fully meets the regulatory requirements for seed packaging bags and cooperates with the traceability platform to implement seed circulation and Traceability of the use process, the equipment is simple and easy to use, 24 hours non-stop operation can ensure the stable operation of the equipment, and does not block the ink system. It is an ideal equipment to prevent repeated codes, wrong codes, and perfect identification of missing codes.
