MASTER BAG 330 Roll-fed Paper Bag Machine (Without Handle) Overview The MASTER BAG 330 is a state-of-the-art roll-fed machine designed for the efficient production of square bottom paper bags without handles. Utilizing a continuous roll of paper, this machine is optimal for high-volume manufacturing, catering especially to the demands of food industries and retail. With advanced automation features including paper feeding, tube forming, cutting, and bottom forming executed in a seamless online process, the MASTER BAG 330 not only maximizes productivity but also ensures significant labor cost reductions. Precision and Efficiency Equipped with a photoelectric detector, the machine maintains precise control over the cutting length, guaranteeing high accuracy in each bag it produces. The system's capability to handle very thin paper at high speeds makes it particularly suitable for environments that require quick turnarounds without compromising on quality. Control System The entire operation is governed by a sophisticated Japanese YASKAWA electronic control system. Managed through a servo motor, this system assures that each paper bag meets stringent quality standards with high stability and minimal maintenance needs. The result is a production line that is not only efficient but also reliable, making the MASTER BAG 330 an indispensable asset for printing plants and paper bag manufacturers seeking to enhance their output. Key Units and Features Paper Material Feeding and Conveyance Unit: Roll feeding with an automatic lifting function simplifies the paper change process during production. Equipped with an unwind air shaft and a hydraulic cylinder lifting control system for seamless operation. Features an automatic tension control system to ensure consistent paper feeding. Paper Bag Forming Unit: The paper is precisely glued on the edges and formed into a tube, which is then precisely cut according to preset specifications. A sophisticated mechanism spreads the tube into a four-cornered bottom, applies glue, and shapes the bottom, transforming it into a square-bottomed bag ready for the next stage. Finished Bag Collection Unit: Once formed, bags are pressed together and conveyed out. An integrated counting system in the bag collection device allows for automatic tallying of finished products, facilitating inventory management and packaging operations.
