◆ The mainframe shafts and rollers all use high-quality steel materials, are processed by grinding, and undergo high-precision computer dynamic balancing correction, with a hard chrome-plated surface.
◆ All transmission gears of the mainframe use 20CrMnTi alloy steel, with carburizing and quenching treatment, hardness HRC58~62; after gear grinding, grade 6 accuracy ensures high color registration accuracy during long-term use.
◆ All transmission parts of the mainframe (shafts, gear connections) use keyless connections (shrink fit), eliminating connection gaps, suitable for high-torque, long-term high-speed operation. Important transmission components of the mainframe all use reinforced self-aligning bearings, simplifying maintenance, and prolonging service life. (Using three major brands: "Harvalo")
◆ The mainframe lubrication system uses a spray-type automatic lubrication system, equipped with an automatic balancing device to maintain the same oil level in each unit.
◆ The mainframe has a preset adjustment function; paper feeding, printing, slotting, die-cutting, automatic zeroing, and automatic reset of combined body memory.
◆ The mainframe working gap adjustment uses a wrench-free quick adjustment, making adjustments quick and convenient.
◆ The mainframe uses variable frequency control, making startup and operation smoother and more energy-efficient.
◆ Equipped with a low-ink warning device, monitoring the working status of the ink supply system in real-time.
◆ Optional: Ceramic mesh roller; doctor blade inking system; stacker.

Carton Part Introduction
Paper Feeding Section
◆ Leading-edge paper feeding method, the air volume can be adjusted according to the degree of bending of the cardboard to ensure smooth paper feeding, with mechanical or German servo options. ◆ Main motor start protection device, the mainframe cannot start if the machine is not fixed. ◆ Continuous or sheet-fed paper feeding is possible. ◆ Double feed rubber rollers, the rubber rollers have anti-overpressure grooves to reduce flattening of the fed cardboard. ◆ Side register plates are electrically controlled with digital display. (Pneumatic automatic alignment can be added.) Rear register is electrically adjusted, and front register gap is manually adjusted synchronously. ◆ Dust removal device. Dust removal brush and suction fan can remove dust from the surface of the cardboard. Dust removal vents can be adjusted segmentally according to the size of the cardboard. ◆ Electronic counter can set production quantity, and automatically alarms when the set quantity is reached. (If touch screen control is selected, the production quantity can be directly displayed on the touch screen).
Printing Section
◆ Quick plate change device, when loading and unloading printing plates, the foot switch electrically controls the forward and reverse rotation of the plate roller. ◆ Printing register phase adjustment adopts PLC and electric digital input 360-degree adjustment, the phase motor is controlled by a frequency converter, and can be adjusted during both shutdown and operation. ◆ Printing register lateral adjustment uses PLC and electric digital adjustment, with an adjustment range of 10mm. ◆ Printing phase fixing device, pneumatic braking mechanism, when the unit is separated for adjustment or cleaning, the braking mechanism limits the rotation of the gear, keeping the original gear position fixed. ◆ The anilox roller adopts a pneumatic lifting device cooperating with the paper feeding system (when feeding paper, the anilox roller automatically drops in unit order, and automatically rises in unit order when paper feeding stops). ◆ Pneumatic diaphragm pump inking, automatic circulation, water washing. ◆ Plate wiping memory function, after cleaning the printing plate, it can return to the original printing position.
Slotting Section
◆ HMI and electric button adjustment dual system operation, can complete the adjustment of slotting box height, phase, and axial movement. ◆ Equipped with a self-locking pre-pressure quick adjustment mechanism, ensuring long-term accuracy between the disc and shaft, and reducing damage to the cardboard during creasing. ◆ The creasing upper roller is wrapped with high-quality polyurethane, ensuring that the cardboard hardness is not damaged. ◆ Synchronous linkage electric axial movement is set, so that the upper and lower creasing rollers, upper and lower slotting knife discs, and guide wheels are adjusted synchronously; self-lubricating and wear-resistant guide mechanism, ensuring long-term correct shift and improving durability. ◆ Creasing roller shafts and slotting roller shafts are made of high-quality alloy steel, and after surface grinding, they are hard chrome plated; they are corrected on two separate rough and fine dynamic balancing equipment to ensure the best balance point is found. ◆ High-quality alloy steel slotting knives are used, and the tooth shape blade width is 7mm.
Die-cutting Section
◆ The rubber pad is mechanically spirally moved horizontally, with a movement distance of 40mm. ◆ Die-cutting register phase adopts PLC and electric digital 360° adjustment, phase motor frequency converter control, and can be adjusted during both shutdown and operation. ◆ Die-cutting roller lateral movement uses PLC and electric digital input adjustment, with an adjustment range of ±10mm. ◆ The gap adjustment between the rubber roller and the die-cutting roller adopts a self-locking structure and is equipped with a pneumatic cylinder for large-range quick adjustment, reducing rubber pad damage and increasing the service life of the rubber pad. ◆ The paper feeding roller gap adjustment adopts a self-locking structure. ◆ Differential compensation device, which allows the urethane roller to slide with the die roller, so that the surface speed of the rubber roller is controlled by the die, making the die-cut carton completely consistent with the shape of the die. ◆ The machine is equipped with a urethane rubber correction device, which can be used after repeated correction of the urethane rubber.
This machine can complete one-color to multicolor printing, slitting, creasing, trimming, slotting, mitering, punching, die-cutting and other multiple processes in one go.
