• GREAT WALL MACHINERY & MANUFACTURING (PHILIPPINES), INC.
    GW-1100 / 1450 / 1800 / 2400 AUTOMATIC FOLDER GLUER MACHINE  is not only suitable for flexo carton
    glue forming, but also fully meets the demand of offset printing glazing and coated carton glue. A standard machine is
    made up of such six parts as the feeder section, the preprocessing folding section, the folding section, the full pressing
    section, the pressure enabling dry section and the counter and convey section. According to the different needs of
    customers, this can be used for the straight line box, the crash-lock box, the four/six corner box and other complex
    shapes of the surface of carton glue function, achieving multi-usage. With PLC control and spilt-box drive, it is endowed
    with stable operation and low noise, The pre-folding section is equipped with spraying humidification and a secondary line
    pressing device that can effectively solve the size seam in the process of tapping. Speed of the formation belt and the
    clappers can be regulated independently, effectively reducing formation of the scissors gap in the gluing process.
    This machine is furnished with operating convenience and steady running, which make it a preference for reducing work
    force in the back-end processing and improving efficiency by the paper-makers.

    Feeder Section:
    ● The pasteboard transportation relies on seven paper feed belts of 100mm width, spacing of the feeding belt is adjusted
    by the tension to be suitable for cardboard with different widths, and the power is supplied from the grain roller.
    ● The feeder section is equipped with baffles on the left and the right sides, which can be adjusted manually based on
    different cardboard width with pneumatic jogging device installed on the left.
    ● Two feeding knives are equipped at the front end of the feeder section, which can be adjusted up and down based on
    different thickness of the cardboard.
    ● Step-less speed regulator ensures convenient and quick operation and steady paper feeding.

    Preprocessing Folding Section:
    ● The spraying and humidifying equipment is installed at the front-end of the pre-processing folding section, humidifying
    the cardboard according to its dry-wet degree. The photoelectric eye controls the humidifying time, which will
    automatically spray and humidify the folding process when sensing it, thus guaranteeing the folding line of cardboard in
    molding not to burst even when the machine runs at a high speed to achieve ideal formation effect and orderly, accurate
    and appealing carton gluing.
    ● Two groups of pressing wheels, one group of rubber thread ones and the other group of steel wire ones, pre-press the
    sprayed and humidified cardboard. The rubber thread ones can avoid the folding line bursting under high speed while
    the deep pressing line can be adjusted by swinging the turbine and the worm manually.

    Folding Section:
    ● According to different cartons and paper boxes,one or more gumming devices are set at the front-end of the final
    folding section, of which the glue spreader is composed of the lower gluing wheel, the upper pinch wheel and the glue
    case. Computer controlled glue spray system can be equipped based on customers' needs.
    ● The folding of 180 degrees between the second folding line and the fourth folding line on the left and the right sides of
    the cardboard is mainly achieved through three 40mm wide bottom belts and two 60mm wide turning belts. Speed of the
    formation turning belt can be independently to control size of the scissors gap.
    ● Many idler pulleys at different angles are set in the left and right sides,positions and angles of which can be adjusted
    according to different paper characteristics and the thickness of cardboard to make folding more smoothly.
    ● Many axial bearings under the bottom belt are installed to support and guide the smooth operation of the belt.

    Full Pressing Section:
    ● According to different widths of the formed carton,the spacing between the left pressing zone and the right pressing
    zone could be automatically regulated by inputting parameters on PLC touch screen.
    ● The paper feed speed should be adjusted according to the whole speed to make the formed cartons enter the full
    pressing assembly in superposition.
    ● The upper and lower conveyor belts' clearance(pressure) should be adjusted according to the shapes and the
    paper characteristics of the formed cartons to transfer the carton to the pressing and creasing section orderly and to
    make the carton bond more perfectly.
    ● Togging device is set at the tail, which corrects the gluing position of the carton through the forth-and-back movement
    of the camshaft gear to ensure bonding precision.
    ● The master control cabinet of the machine is fit on the full pressing assembly, convenient to inspect and operate the
    whole line.

    Pressure Enabling Dry Section:
    ● The left and right guide poles are set at the front-end that can adjusted by
    motor according to the dimension of the formed cartons.
    ● Wind pressure spout is set to prevent the formed cartons from wandering,
    interlacing at high speed output, which may bring about jam, damage the carton chain and affect normal operation of the
    machine.
    ● Two photoelectric switches are set at the top and bottom of ejector baffle, whose upper and lower limits are set
    according to the piling height of the formed cartons,automatically controlling the paper ejection rate and time to match
    with the whole line speed.
    ● The ejector baffle can be electrically adjusted forth-and-back according to different length of the formed carton.
    ● Flexible moderate belts imported ,which will not crush the finished product, are used.

    Counter and Convey Section:
    ● The humanized slope-type conveyor structure is convenient for operation to alleviate the labor intensity.
    ● Two ejecting reamers are set,which can electrically adjusted back-and-forth based on shape and length of the formed
    carton.
    ● A set of pinch wheels are set, which can press uniformly, buffer the impact force to avoid abnormal paper ejection.
    ● Stack and ejection quantity can be set ejected orderly based on customers’ needs.
    ● Pneumatic front retainer and reciprocating push rod are used for more accurate and rapid paper ejection.
