Product Description Product SpecificationProduct IntroductionThis machine is designed to manufacture square bottom paper bags with handles from paper roll, paper patch roll and paper rope, and it is an ideal equipment for producing paper handbags fast. By implementing steps including flexo printing, handle making, handle application, tube forming, tube cutting and bottom forming within a fully automatic process, this machine can effectively save labor costs. The equipped photoelectric detector can correct cutting length, so as to ensure cutting precision. SIEMENS PLC system ensures that the machine can perform quickly and stably, as well as reduce adjusting time for different bag sizes. Special bags collection platform and counting function, improve packing efficiency of paper bags packing. Thanks to perfect technologies and fast production speed, this machine can produce paper handbags with high quality in many different forms, which are especially suitable for food and clothing industries.Main Technical ParameterModelLTY-ZD-QFJ21+H75+B75+T41500BCPaper Roll Width630~1530mmMax.

Production Speed120bags/minTotal Power54kwTotal WeightApprox. 28000kgOverall DimensionL18000mm×W6000mm×H3100mmNote: the parameters above are not absolute; operator's skills, temperature, moisture, material and size of paper, categories and quality of glue can affect production speed, rejection rate, and applicable range of machine. Detailed SpecificationUnwinding SectionSeparate single-station unwinding roll stand with hydraulic lifting device.Air shaft for paper reel loading, equipped with air gun.Magnetic powder brake for unwinding and automatically constant tension controller for unwinding tension control. EPC web guide control system for material alignment. Automatic Stop Function: the machine stops automatically when materials are broken.Automatic Replacement Alarm Function: the alarm will be triggered automatically to inform the operator for replacement when material reel diameter becomes too small.4-color Printing SectionSpace is saved because of stack-style. Rubber cylinder transfers ink onto paper; when the machine stops, independent motor drives, the cylinder to continue rotating to avoid ink drying.Ceramic anilox roller for ink transferring (LPI can be customized).When the machine stops, anilox rollers and printing cylinders are disengaged automatically.Equipped with one set of printing cylinders (printing length can be customized).Color Registration Mode:Manual.The pressure between printing cylinder and base cylinder, as well as the pressure between anilox roller and printing cylinder can be adjusted by hands. It is possible to adjust on both sides at the same time or on one side.The ink amount on anilox roller can be adjusted by the corresponding eccentric worm gear.Main Technical Parameter:Inline PrinterT41500BCMax.

The positions of pressing wheels can be adjusted.Equipped with 3 forming moulds.(they can make all sizes)Bottom Forming Section The whole machine is mainly controlled by inverter-fed motor.Materials feeding is managed by Independent Servo Draw Roll Drive System.Automatic photocell correction system is used for running materials.Rotary serrated cutter with elliptical gears.Adjustable bottom creasing device is used to adjust the bag bottom size.Bottom opening cylinder with split cam is adopted for the stretch length adjustment of bottom opening.Multi-layers bottom forming drum, center grippers, second tuck clamps, and drum grippers are adjustable for ease of changeover.Automatic Disengaging Function: bottom gluing is prevented for empty feeding to avoid contamination to the surface of the drum. The clutch function in bottom gluing part is managed by pneumatic control.Bag Collection SectionPaper bags are delivered by belt, and collected at vertical workbench, which is easy for operations.Bag collection drving wheels are driven by separate motor.Bag shaping stucture consists of pressing rubber rollers. Separate servo motor controls the transverse delivery of finished products, and is able to adjust the bag releasing distance, which is convenient for counting.Control SectionThe whole machine is centrally controlled by Original German SIEMENS PLC system, which has self-diagnosis function and monitors the machine status.Touch screen is adopted for input control and machine status display.The bag tube length is controlled by SIEMENS servo motor.Bag collection speed is controlled by separate motor.The whole machine is mainly controlled by inverter-fed motor.Automatic counting; batch-delivery and acceleration-delivery functions.
