Square Bottom Paper Bag Machines are essential tools in modern packaging industries, automating the production of various paper bags such as shopping bags, gift bags, and food bags. These machines handle functions like printing tracking, cutting, bottom indentation, folding, and gluing. Equipped with advanced technology such as German photoelectric sensors and servo motors, they ensure precise tracking, alignment, and efficient, stable operation using both plain and printed paper.
Key components of the Square bottom paper bag machine include the reel feeding unit with hydraulic lift and tension control, and the forming unit with servo motors and touch screen interface. Materials used include stainless steel for tube formers and anodized aluminum for rollers. The machine features a dynamically balanced cutter roller assembly, centralized automatic cooling lubrication system, and an electrical panel with automatic fault detection and refueling systems, ensuring continuous, efficient operation.
The Square Bottom Paper Bag Making Machine manufacturing process starts with the reel feeding unit, where heavy paper reels are lifted and fed automatically using a hydraulic system. An automatic tension control system maintains paper handling. The machine also features an edge correction system for accurate tube formation and an automatic glue dispensing system tailored to paper quality and speed. In the forming unit, operations like tube formation, side pasting, bottom creasing, and gluing are performed, with servo motors ensuring precise cutting and stable performance.
