This device adopts a PIC programmable 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. This machine adopts a piston pump type to smoothly inject quantitative materials into the packaging bag through the pipeline, thereby solving the adverse effect of material retention caused by weak fluidity during the operation of general automatic packaging machines. Alternatively, it can be equipped with optional or automatic processes such as measuring, bag making, filling, sealing, coding, adding easy to tear edges, cutting (cutting methods: straight cut, serrated cut, continuous easy to tear cut), counting until the product output is completed in one go. Product Description: Usage: Suitable for packaging liquid paste materials in industries such as food seasonings, beverages, pharmaceuticals, and daily chemical products, such as tomato sauce, butter, honey, shampoo, cosmetics, etc.
