3. Technical Description of YY-DP-400 Left-Right Winding Automatic High-Speed Single-Sheet Wet Wipe Machine
This equipment is a fully automatic and intelligent machine designed for large-scale production of single-sheet independently packaged wet wipes (including disinfectant wet wipes, makeup remover wipes, cleaning wipes, alcohol wet wipes, etc.). It integrates full-process technologies of “raw material handling – humidification & impregnation – precise forming – independent packaging – finished product output”. Its core advantages lie in high-speed stability, controllable precision, and strong compatibility, which can meet the efficient production needs of various types of wet wipes. The following sections elaborate on its technical architecture, core modules, precision assurance, and intelligent design from four dimensions.
3.1 Equipment Technical Architecture & Core Positioning
3.1.1 Technical Positioning
Production Mode: Fully automatic with no manual intervention throughout the process. From the unwinding of spunlace nonwoven fabric/degradable base material to wet wipe cutting, folding, impregnation, packaging, coding, and finished product conveying, no manual step-by-step operation is required. It is suitable for “single-shift 8-hour” continuous production scenarios.
Efficiency Indicators: The designed speed reaches 450 sheets/minute, and the actual production speed is 250-350 sheets/minute (dynamically adjusted based on base material weight and packaging film thickness). The maximum theoretical daily output can reach 168,000 sheets (calculated as 350 sheets/minute × 8 hours × 60 minutes), making it a core equipment for medium-to-large wet wipe production lines.
Product Compatibility: It supports multi-specification wet wipes with folded sizes of (80-130)×(50-85) mm and unfolded sizes of (160-260)×(150-300) mm. It is compatible with 35-100g/m² spunlace nonwoven fabric, degradable materials, and multi-material packaging films such as PE/PET and OPP/PE (aluminum-plated film), meeting the product needs of different application scenarios (household, commercial, basic medical disinfection).
3.2 Technical Analysis of Core Production Modules
3.2.1 Raw Material Handling Module: Stable Feeding, Reduced Shutdown
Unwinding & Splicing Technology: Adopts a “spunlace nonwoven fabric center unwinding” design, combined with an automatic splicing mechanism, supporting base material rolls with a width of 150-300 mm. No shutdown is required during roll change; the connection between old and new rolls can be completed in an extremely short time (<30 seconds), increasing the effective operation rate to over 92% (the effective rate of traditional single-roll unwinding equipment is about 85%).
Double Deviation Correction System: Both the base material (nonwoven fabric) and packaging film are equipped with independent deviation correction devices (equipped with RIKO fiber amplifier and Panasonic LX-101 color mark sensor). They detect material deviation in real time (precision ±0.5mm) and automatically adjust the material position through the servo motor, avoiding cutting misalignment and packaging film wrinkling caused by base material deviation, and ensuring the precision of subsequent processes.
Tension Control: The packaging film is controlled by a combination of “Delta inverter (VFD4A2MH43ANSAA) + tension sensor”. The tension is dynamically adjusted according to the packaging film thickness (2.5-7 mils) to prevent film stretching/deformation (for thin films) or breakage (for thick films), adapting to packaging films of different toughness such as OPP/CPP and PET/CPP.
3.2.2 Humidification & Impregnation Module: Uniform Liquid Control, Adaptable to Multi-Formulas
Multi-Mode Liquid Feeding Technology: Integrates “spray + soak” two liquid feeding modes, which can be switched with one click via the touchscreen:
Spray Mode: Uses “pipe-type nozzles + Nanfang stainless steel water supply pump” for low-viscosity liquids such as alcohol wet wipes and disinfectant wet wipes (e.g., 75% alcohol, quaternary ammonium salt solution), achieving uniform spraying (liquid absorption deviation of each wet wipe <5%);
Soak Mode: Suitable for high-viscosity liquids (e.g., makeup remover liquid containing moisturizing ingredients). The base material is impregnated and then the liquid is controlled by squeeze rollers to ensure stable liquid absorption (the pressure of squeeze rollers can be adjusted via PLC, with liquid control precision ±0.2g/sheet).
Liquid Circulation & Mixing: The 400L liquid storage tank (equipped with Nanfang stainless steel return pump) is linked with a “mixing barrel + continuous mixing system” to stir the liquid in real time (adjustable rotation speed: 100-300r/min), preventing component precipitation (e.g., stratification of bactericides in disinfectant wet wipes). At the same time, the unabsorbed liquid is returned to the liquid storage tank through the circulation pipeline, increasing the liquid utilization rate to over 98% and reducing waste.
Liquid Level Monitoring: The water bucket is equipped with a “double-position float liquid level switch” to monitor the liquid level of the storage tank in real time. When the liquid level is low, an alarm is automatically triggered to prompt liquid replenishment, avoiding “dry sheets” of wet wipes due to liquid shortage.
3.2.3 Forming & Folding Module: Precise Folding, Online Adjustable
Dual Folding Methods: Supports “Z-type” and “W-type” folding. The folding mechanism is driven by a Delta servo motor (ECMA-C10807RS, 750W), with folding precision up to ±1mm. For different folding sizes (e.g., 80×50mm, 130×85mm), the folding position can be directly adjusted via the touchscreen (equipped with KTC-500 linear displacement sensor, positioning precision ±0.1mm) without disassembling mechanical parts, and the changeover time is <30 minutes.
High-Precision Cutting System: Adopts a combination of “440C alloy-inserted cutting knife + independent bottom knife” (e.g., YY-DP01-17-06 cutting knife: 350×1.2×25mm). The blade hardness reaches HRC58-60, with a cutting service life of 800,000-1,000,000 sheets. The cutting mechanism is controlled by a Delta servo driver (ASD-A3-1521-E), and the cutting speed is synchronized with the base material feeding speed (phase adjustment precision ±0.1°), avoiding “connected cuts” (multiple sheets stuck together) or “missing corners” (incomplete cutting).
3.2.4 Packaging & Forming Module: Efficient Sealing, Adaptable to Multi-Specifications
Dual Sealing System:
Middle Sealing System: Adopts a “traction preheating + longitudinal sealing heating” design. The heating tube (φ8×120mm) is equipped with a YUDIAN AI-207 temperature controller (temperature control precision ±2℃). The heating temperature is set according to the packaging film material (e.g., PE film melting point: 110-130℃; PET film melting point: above 250℃) to ensure firm middle sealing (peel strength ≥3N/15mm, complying with GB/T 19741 standard);
Transverse Sealing System: Driven by “independent mechanical cam + Delta 3KW servo motor (ECMA-F11830RS)”, the sealing speed is synchronized with the production speed. The transverse sealing spacing can be adjusted via PLC, adapting to packaging bag sizes of (100-200)×(60-80) mm. The cam structure ensures stable transmission, with transverse sealing deviation <0.3mm, avoiding wet wipe moisture due to “incomplete sealing”.
Online Coding & Finished Product Output: Integrates a coding system (suitable for production date, batch number, etc.) with coding position precision ±1mm. The finished products are output through a “conveyor belt controlled by Delta inverter (VFD2A8MS21ANSAA)”. The friction force of the belt is dynamically adjusted with the speed (adjustable speed: 0-5m/min) to prevent finished product accumulation or conveying jams.
3.3 Precision & Stability Assurance Technology
3.3.1 Mechanical Precision Assurance
Core Component Processing: Main mechanical components (such as folding rollers, cutting knife holders, and sealing molds) are manufactured by a “CNC 4-axis machining center” with a machining precision of IT7 grade (tolerance ±0.015mm), ensuring smooth operation after component assembly and reducing precision deviation caused by mechanical gaps.
Wear-Resistant Component Selection: Key wear parts are made of high-durability materials, such as 440C alloy-inserted cutting knives (service life over 800,000 sheets), imported precision bearings for conveying roller shafts (service life 6-12 months), and hard chrome-plated surfaces of packaging film traction wheels (hardness HRC62, wear-resistant), reducing maintenance frequency.
3.3.2 Electrical Control System Precision
Bus-Type Control Architecture: Adopts “Delta AS516E-B PLC + Delta bus motion control system” to realize real-time data interaction between “servo motor – inverter – temperature controller – sensor” (response speed <10ms). The synchronization precision of each process (cutting, folding, sealing) is ±0.1mm, avoiding operational incoordination caused by signal delay.
HMI & Recipe Management: The 10-inch Delta touchscreen (DOP-110WS) supports “recipe storage and recall”, which can store more than 100 sets of production parameters (such as the size, liquid dosage, and sealing temperature of different wet wipes). During product changeover, recipes can be directly recalled without repeated debugging, increasing changeover efficiency by 50%.
Precise Temperature Control: 8-channel independent YUDIAN AI-207 temperature controllers (equipped with K-type temperature probes) independently control the temperature of electric heating components such as middle sealing, transverse sealing, and heating rings. They display and record temperature data in real time (temperature curves within 72 hours can be traced), meeting the production hygiene requirements for food-contact wet wipes (e.g., temperature fluctuation of heating components <±2℃, avoiding harmful substance decomposition from packaging film due to overheating).
3.4 Safety & Maintenance Design
3.4.1 Safety Protection Technology
Multi-Layer Safety Guarantee: Equipped with “emergency braking system (3 KND BS542C emergency stop buttons) + acrylic protective cover + blade safety guard”. The emergency stop response time is <0.5 seconds, and the equipment automatically shuts down when the protective cover is opened. At the same time, a safety door interlock is set to prevent operators from touching moving parts (such as cutting knives and folding rollers) by mistake.
Electrical Safety: The circuit system is divided into “main circuit (380V) + control circuit (24V)”. The main circuit is equipped with LS circuit breakers (BKN series), ABB contactors, and thermal relays to prevent overload and short circuit. The control circuit uses a DELTA DRL-24V240W switching power supply, and low-voltage power supply reduces the risk of electric shock. Major electrical components have passed CE certification, complying with international safety standards.
3.4.2 Maintenance Convenience Design
Compact Structure: The equipment dimensions are only 6000×1100×1700mm (L×W×H), saving about 15% of installation space compared to equipment with the same capacity. Maintenance windows are reserved at key maintenance positions (such as cutting knives, heating tubes, and deviation correction devices), allowing component replacement without disassembling the entire machine.
Standardized Wear Parts: Core wear parts (such as cutting knives, bottom knives, heating tubes, and PU belts) adopt standardized specifications (see the parts list for details, e.g., YY-DP01-08-07 bottom knife: 130×10×28mm). They can be stocked in batches, no customization is required during replacement, and maintenance costs are reduced by 20%. A dedicated toolbox is also provided for daily maintenance.
Status Monitoring & Alarm: The touchscreen displays the equipment’s operating status in real time (such as motor speed, temperature, and liquid level). When a fault occurs (such as motor overload, abnormal temperature, or material shortage), an audible and visual alarm (three-stage indicator light + buzzer) is triggered immediately, and the fault cause and troubleshooting steps are displayed on the screen, shortening the fault handling time (average <15 minutes).
