This device adopts a microcontroller control board, and the LCD display screen intuitively displays various technical parameters of the operation settings. It can also be equipped with Chinese and English display screens for operation, with touch sensitive button control, making it easy to achieve human-machine dialogue. Advanced photoelectric recognition, bag making length, and the ability to directly set bag length on the operating surface. When using packaging materials with color codes, the color codes can be captured, making bag pulling synchronous, smooth, and accurate. The equipment is easy to operate and maintain, and easy to adjust. Using an adjustable measuring cup and volumetric measurement method, the packaging quantity can be adjusted according to actual needs. This machine automatically completes measurement, bag making, filling, inflation, sealing, coding, adding easy to tear edges, cutting (cutting method: serrated incision, continuous easy to tear incision), counting until the product output is completed in one go.
