Functions and features
The paper feeding system utilizes advanced German leading-edge feeding technology, and the paper feeding roller shaft is made of bearing steel. The control panel features a 7-inch color touchscreen HMI, enabling communication and operation between the paper feeding, printing, slotting, and die-cutting departments. It can control and display current operating phase, overall machine speed, counting stop for order change, plate lifting delay, constant speed adjustment of the adsorption fan and dust removal fan, alignment time, continuous operation, and sheet spacing settings, among others. Adjustments are quick, and operation is safe and easy.
All printing rollers (including the φ410 printing plate) undergo dynamic balancing. Made of steel plate, with surface grinding and dynamic balancing, they operate smoothly and are suitable for high-speed operation.
The slotting department's electrical operation utilizes a touchscreen-controlled PLC programming automation system. Based on the order data (length * width * height) of the paper products, the computer system automatically schedules the slotting to the required position with a single button press. Manual fine-tuning of the slotting position is also possible according to customer needs. The color human-machine interface features menu storage and automatic compensation and correction of shift distance. The shifting motor uses a frequency converter-controlled Delta Motor drive unit from Taiwan. The servo motor speed is adjusted according to the distance, allowing for synchronous adjustment of the four blades, significantly saving blade adjustment time and improving work efficiency.
The die-cutting unit is equipped with a single servo-tracking independent motor drive. The advantage is that the torque resistance of the die-cutting unit is not transmitted to the printing unit, thus preventing any impact on print quality and precision.
faq
1
Q1: How does the GS-1428 maintain alignment accuracy during high-speed printing of 200 sheets per minute?
A: Our DePack GS-1428 uses ultra-thick integral cast iron wall panels (precision-manufactured by CNC machining centers), providing exceptional rigidity and completely eliminating mechanical resonance under high-speed operation. All transmission gears are made of high-quality alloy steel, carburized, quenched, and precision ground, coupled with keyless connecting rings to ensure zero-backlash transmission under high torque. The four-color registration accuracy is precisely controlled within 0.5 mm, resulting in extremely fine and regular printed patterns.

Q2: What is the principle behind the "Lower Adsorption" technology seen in the video? What are its advantages?
A: Traditional printing presses rely on pressure rollers, which can easily collapse corrugated paper. Our four-color unit uses full-process vacuum adsorption for carton feeding. After the cardboard enters the printing unit, it is firmly adsorbed and advanced by the vacuum box below. The surface of the feeding rollers is made of ultra-wear-resistant ceramic material. This design avoids the pressure rollers squeezing the cardboard, perfectly protecting the inherent strength of the corrugated board and ensuring no misalignment or scratches on the ink surface during four-color overprinting.

Q3: What configuration does this four-color machine use for its inking and doctor blade systems?
A: Each printing unit is equipped with a high-line-count laser-engraved ceramic anilox roller and an industry-leading fully enclosed single/double doctor blade system. Thanks to precise cavity fluid dynamics design and automatic pneumatic/cylinder clamping technology, the doctor blades clean the ink, and the inking is extremely uniform. The fully enclosed design effectively prevents solvent evaporation from the ink, saving you significant ink costs each time you wash the machine and change the ink.

Q4: The biggest concerns with four-color printing presses are slow order changeovers and cumbersome alignment. How efficient is the order changeover for the GS-1428?
A: We employ an advanced intelligent centralized control system, with several 10-inch large touchscreen control panels standard on the side of the machine. The slotting unit supports full-row computer-controlled knife arrangement: during order changeover, simply input the carton's "length x width x height" on the screen, and the servo system will automatically move the knife into position with one click. The machine also features fully automatic encoder zeroing and plate-wiping position memory functions. After wiping the plate and closing the unit, it automatically resets with one click. Typically, only two test sheets are needed before starting operation, greatly saving setup time and paper waste.

Q5: Is paper feeding smooth when encountering large-area bends, warps, or very thin E-flute cardboard?
A: Absolutely not. DePack uses the most advanced leading-edge pressure-free adsorption paper feeding technology, and comes standard with a high-power variable frequency fan and multiple anti-static dust removal brushes. You can fine-tune the airflow in segments directly on the touchscreen according to the size and curvature of the cardboard, flattening and compacting the warped cardboard. Whether it's high-grade color box cardboard as thin as E-flute or multi-layer cardboard up to 12mm thick, it can be inserted quickly, smoothly, and precisely.

Q6: I noticed the grooving unit's movements in the video are quite unique. What is its blade structure like?
A: Our grooving unit uses a high-strength double-blade single-axis grooving structure. The internal gear box height adjustment system ensures that lubricating oil will never leak and contaminate the cardboard box. The grooving blades are made of high-quality alloy steel, undergoing rigorous heat treatment and tooth grinding, possessing both ultra-high hardness and toughness, resulting in smooth, burr-free cuts. All pre-pressure rollers and creasing rollers are also synchronously controlled by a computer, allowing for one-step adjustment of lines and blades.
7
Q7: What unique designs does this machine's die-cutting unit have to save us money?
A: Our die-cutting unit is equipped with a mechanical urethane pad roller with a 50mm lateral swimming system and a speed difference compensation device. During operation, the pad roller automatically moves slowly left and right, ensuring that the cutter does not repeatedly cut in the same place, resulting in extremely even wear. In addition, the machine has a built-in electric grinding automatic repair mechanism. When the pads wear out, there is no need to disassemble them; they can be directly smoothed and repaired on the machine, significantly reducing the frequency of consumable replacements.
8
Q8: With the high operating speed of the four-color inline machine, how is worker safety ensured during daily operation?
A: The machine's safety features are top-notch: all units use electric opening and closing combined with pneumatic locking; the main motor cannot start unless the machine is completely locked. Continuous alarm bells and warning lights alert workers during movement. Each unit is equipped with an easily accessible emergency power-off (E-stop) switch. Even more thoughtfully, we've installed an electronic monitoring camera and control panel on the front of the main unit, allowing workers to monitor the paper feed status from the control panel without any blind spots, ensuring comprehensive safety for both workers and machines.

Q9: What brands do the core electrical and mechanical components of this DePack GS-1428 come from?
A: For high-end overseas buyers, we use top-tier international and domestic supply chains for all machines, ensuring worry-free procurement and maintenance locally: Electrical and Servo Systems: Siemens inverter-controlled main motor, Schneider original contactors/relays/operating buttons, and a complete set of high-power frequency converters from Delta (Taiwan). Bearings and Pneumatics: Japanese-made NSK grade silent high-precision bearings; a complete set of brand-name cylinders and solenoid valves from Airtac/Yadake (Taiwan). Ink System: Wuhan/Zhejiang "Desheng" pneumatic single/double-direction diaphragm high-flow ink supply pumps.
10
Q10: What are the delivery time, container transportation, and after-sales parts arrangements for this 1428 four-color integrated inkjet printer?
A: As it is a large four-color integrated machine, after being disassembled, it needs to be safely loaded by sea using standard 40HQ (high cube) and 20GP (flat container). We can complete lean manufacturing and arrange shipment within 100 days after receiving the 30% prepayment. A complete set of Toolbox adjustment tools, standard basic installation drawings, Chinese and English operation manuals, and detailed circuit/pneumatic schematics are included free of charge, ensuring worry-free after-sales service.
