Functions and features

Front edge paper feeding system

Utilizes a large volume of suction air for assistance. It can precisely convey even slightly curved or thin paper sheets without damaging the corrugated structure. Dust removal device: Equipped with a powerful suction fan and electrostatic brush, it removes surface paper debris before the paperboard enters the printing process, ensuring the cleanliness of the printing.

Flexo Printing Unit

Utilizing eco-friendly water-based ink, it performs high-precision, multi-color pattern and text printing on the surface of cardboard. Ceramic roller ink applicator: Precise and uniform ink transfer, supporting high-line-count fine printing. Vacuum Transfer: The cardboard is transferred between each color group through vacuum suction, ensuring precise color registration (errors typically within ±0.5mm) and preventing the cardboard from deviating. Quick Wash Ink System: Intelligent automatic ink washing and color changing, significantly reducing the time for changing sheets.

Slotting Unit

Performs longitudinal and transverse line pressing on the cardboard, as well as slotting (cutting the gap for the lid of the carton) and cutting tongues. Full computer-controlled axial/radial adjustment: The position of the slotting knife holder and the height of the line pressing wheels are all controlled by computer servo systems. When changing the sheet, the cutting is automatically aligned, with high precision. Double-pressure line structure: Combining pre-pressure and main pressure to prevent the paperboard from bursting when being pressed, ensuring smooth subsequent folding.

Die-cutting Unit

For non-standard shaped cartons (such as handle holes, airplane boxes, latch handles, irregular ventilation holes, etc.), the die-cutting unit uses die-cutting rollers to perform punching and shaping. Line Speed Compensation: Automatically tracks and compensates for the diameter changes of the die-cutting rubber pads (Yuli rubber pads) due to wear, ensuring consistent die-cutting dimensions. Rubber pad repair for micro-motion device: Automatically smooths the surface of the rubber pad, extending its service life.

Folder Gluer Unit

Spray glue on the flap of the carton and fold the cardboard neatly and firmly to bond it together. Glue Spray System: Utilizes a non-contact high-frequency electrically controlled glue sprayer valve, combined with photoelectric detection. It automatically adjusts the amount of glue sprayed according to the vehicle speed, saving glue and preventing overflow. Ensures that the carton folds evenly on both sides and prevents misalignment.

Counter Ejector & Strapping Unit

The cartons are neatly counted, aligned, stacked, and automatically transported to the strapping machine for bundling, and the finished products are directly output. It is divided into drop-type/ upward-push type counting. This is related to the previous folder gluer. Folder gluer have three types: straight out, small drop down, and big drop down.

Straight out

For small cardboard with dimensions within 1200*2400.The stacking is done using the upward-push method.

Small drop down

For slightly larger-sized cartons.The stacking is done using the drop method.

Big drop down

For larger-sized cartons.The stacking is done using the drop method. The drop-down design is to prevent the large cardboard from folding downwards, as the cardboard might become too large in this case. It hit the ground, causing damage to the cardboard.The drop-style stacking can also make the bonded parts of the cardboard press against the box more firmly.

faq

Q1: How can high-precision registration (within ±0.5mm) be ensured when the conveying line is operating at high speed (>250 sheets/minute)?

Vibration and paperboard deformation at high speeds are the main causes of inaccurate registration. Technical support: Hardware side: The equipment should adopt high-precision helical gear transmission (hard tooth surface grinding, reverse clearance structure) or independent servo direct drive technology. Control side: An independent servo control system with feedforward compensation is introduced to real-time correct the slip errors caused by uneven thickness of the paperboard.

Q2: What is the "Intelligent Recipe Management System (PMS)" for the linkage line and what technical challenges does it address?

The traditional process of changing the layout requires manual adjustments of the cutting tool, guide plates, and pressure, which is time-consuming and prone to errors. Intelligent solution: The macro control system connects to the ERP/MES system of the factory to enable one-click order change. The hundreds of servo axes for tasks such as paper feeding, printing, slotting, die-cutting, and box gluing are automatically adjusted to the correct positions within 1-2 minutes, significantly reducing the switching cost for short-run orders.

Q3: How to optimize the parameters of the assembly line based on the physical characteristics of corrugated cardboard (such as warping, low weight) before production?

Corrugation of the cardboard: If it warps upwards, reduce the gap between the front paper holder and increase the suction negative pressure for the front edge paper feeding; if it warps downwards, reduce the height of the rear paper support bracket. Low weight/high strength corrugated sheets: Fine-tune the gap between the paper feeding rollers to prevent the corrugated sheets from being crushed (it is recommended to use non-contact paper feeding or vacuum suction transmission) to ensure the forming strength of the carton.

Q4: During the production process, how to prevent and handle the "wide and narrow openings (scissor-like openings)" that occur in the box-folding section?

Production inspection: Check the alignment and depth of the pressing rollers (trace rollers) in the slotting section. Insufficient or misaligned pressing is the main cause of the wide and narrow openings. Dynamic fine-tuning: By using the left and right independent forming guiding belts of the folding part, the micro-difference speed is adjusted to compensate for the difference in frictional resistance on both sides of the paperboard.

Q5: During the "color change and ink cleaning" process after production, how can the cleanliness and production line availability rate (OEE) be balanced?

An automatic quick-washing system (Smart Wash) has been introduced. The system can automatically complete the "drainage - water injection - rinsing - air drying" cycle within 3 to 5 minutes. When making production orders, the principle of "from light colors to dark colors" is followed (such as yellow first, then red, and finally black), which reduces the contamination of dark colors on light colors and shortens the ink washing time.

Q6: When packaging companies purchase assembly lines, how do they decide whether to choose "bottom printing type" or "top printing type"?

Bottom printing type assembly line: The printing surface is facing downwards. The advantage is that after printing, the cardboard directly enters the slotting and downward folding for box assembly, the entire line operates smoothly, the corrugated board does not flip, and it is suitable for large quantities and standard cartons (such as beer boxes, beverage boxes). Top printing type assembly line: The printing surface is facing upwards. The advantage is that it is convenient for operators to observe the printing effect and wipe the printing plate. Usually, it is followed by upward folding and box assembly or independent die-cutting and stacking, suitable for fine printing and short-term, variable order structures.

Q7: Regarding the "box bonding section" of the linkage line, what core parameters should the glue spraying system (Gluing System) focus on? Selection criteria:

Nozzle response speed: Must support non-contact point or line spraying of adhesive at high speed (matching 300 meters per minute vehicle speed). Detection of integration degree: It is necessary to select and equip with the glue fluorescence agent detection (UV detection system), and automatically remove the defective boxes that are not coated with glue or have excessive glue, to prevent defective products from flowing into the customer end (a pain point in after-sales service).

Q8: When the linkage line transitions from the "die-cutting/etching section" to the "folding and box-stuffing section", how can technical means be used to solve the problem of "paperboard accumulation" or "tearing" caused by the force pulling?

Technical analysis: At the front end, the paperboard moves independently as a single sheet (etching/die-cutting). Once it reaches the rear end, it becomes continuously clamped by a belt for folding. If there is a slight error in the mechanical line speed between the two sections, at high speeds, it will cause the paperboard to collide (get stuck) or tear (be pulled apart) in the transition zone. Technical guarantee Dynamic speed difference compensation: The servo motor in the folding section receives the encoder feedback from the die-cutting roller at the front end and performs microsecond-level speed feedforward compensation. At the same time, an air suction conveyor belt is configured in the transition zone to use air flow for shock absorption, buffering the physical speed difference between the two sections.

Q10: Are there any issues such as glue splashing, glue overflow, or poor adhesion in the box sealing section?

Possible causes: Glue splashing/glue overflow: The pressure of the glue spraying valve is too high, or the timing (photoelectric sensor) for glue spraying is not properly adjusted. Poor adhesion: The amount of glue applied is too little, the quality of the glue is poor, or the pressure in the pressing section (the belt pressing section) is insufficient. Solution: Adjust the controller of the glue spraying machine, automatically optimizing the glue spraying pressure and delay time according to the vehicle speed. Check the solid content of the glue, increase the application amount of the glue; tighten the leveling and pressing belt before the finished product is discharged, and extend the holding time.
