This device adopts a microcontroller and a liquid crystal display screen to intuitively display various technical parameters of operation settings. It can also be equipped with Chinese and English display screens for operation, with touch sensitive button control to easily achieve human-machine dialogue. High precision photoelectric recognition system, bag making length controlled by cursor; The bag length can also be directly set on the operating surface. When using packaging film with color codes, the first bag can capture the color codes, making the bagging process synchronized, smooth, and accurate. Reasonable design and simple structure make equipment operation and maintenance simple, easy, fast, accurate, and highly automated. If all the functions of this machine are fully equipped, it can automatically complete quantitative, bag making, filling, (inflation), sealing (optional sealing effects such as mesh, straight line, smooth, etc.), (coding), ("-", "V" - shaped easy to tear mouth), cutting (cutting methods: serrated cutting, easy to tear bag connection, flat cutting, etc.), counting until the product output is completed in one go. This machine can also be optionally equipped with punching machines, automatic feeding machines, belt output machines, etc., to maximize the performance of the machine and achieve automatic feeding, automatic packaging, and automatic production of finished products. Using adjustable (or universal) measuring cups and volumetric measurement methods, the packaging quantity can be changed according to actual needs.
