All processes can be made in one bag making machine to form the paper bag, from the paper roll, printing, side gluing, paper patching, tube forming & cutting, handle hole cut, bottom creasing & gluing and forming to bags collection in the control of seven Mitsubishi servo motors imported from Japan to ensure the high precision and stability, simple maintenance and high efficiency.
| FEEDING UNIT The roll paper fixed on the air expanding mandrel can be fed by swing arm which is equipped with lifting hydraulic system. With an alarm function, the feeding unit will sound alarm when there is no paper feeding. Improved surface smoothness of the paper during the feeding is achieved due to the web guide and uniform tension control. Paper rolls can be easily changed by pressing a button. |
| PATCHING UNIT This unit adopts an abreast double-knife to ensure the synchronization of the film patch or paper patch. Gluing, traction and cutting of the patch rolls are all controlled by servo motors. After putting the glue on desired locations and folding by a pneumatic roller, the system realizes the automatic functions of paper feeding, conveying, window gluing, film slitting and patching to produce the ready paper bags through a second roller mechanism. |
| SIDE GLUING UNIT A glue level sensor is used to detect the amount of glue left in the machine. The glue dispenser is used to apply adhesive to the desired locations of the paper. |
| BAG FORMING UNIT Form the paper with patches and side glue into the tube; and cut into separate pieces based on the settings. Afterwards, these separate tubes will be sent to the drum to open the four corners, then have the bottom glued and sealed, finally form the square shape. |
| BAG COLLECTING UNIT Compress the bags and outlet the bags. The number of paper bags can be processed and presented by the automatic collection and counting system. |
