Touch screen is adopted for input control and machine status display, so as to finish machinecorrection easily.2. Equipped with originally imported SIEMENS electrical system and servo motor drive, to make themachine run steadily.3. Germany SICK photoelectric detector is used to track the material to be printed, reduce theadjusting time and improve production efficiency4. Separate single-station unwinding rollstand with hydraulic lifting device; Convex-type inflatable shaftfor loading material (or shaftless loading); Magnetic powder brake for unwinding and automaticallyconstant tension controller for unwinding tension control; EPC web guide control system for materialalignment; alarm function for reminding replacing material and stopping-machine device fordetecting material broken.5. The handle making component is an independent machine, which is driven by servo motor andsynchronized with the main motor; handle length is adjustable according to bag size.6. The cutting and gluing of paper handles are controlled by servo motors, as synchronous as the tubcutting of the main machine; contact rollers transfer pattern is adopted in gluing paper handles;vacuum suction pattern is adopted in transferring handles onto conveyer belt; handles arecompressed onto the paper web with a series of pneumatic rollers, to ensure the pasting strength.7. Adjustable forming mould structure (side sealing is above the forming mould); automaticglue-spraying device with automatic disengaging function is used for side gluing.8. Rotary serrated cutter (or flat-blade cutter) with elliptical gears is used for cutting; the cutting lengthcan be corrected by SICK photoelectric detector; Multi-layers bottom forming drum, center grippers,second tuck clamps, and drum grippers are adjustable for ease of changeover; automaticdisengaging function (bottom gluing is prevented for empty feeding to avoid contamination to thesurface of the drum).9. Paper bags are delivered by belt, and collected at side workbench, which is easy for operations;automatic counting function.10. Automatic lubricating oil supply system.
