Product Introduction
Keypack Intelligent WS-350 Horizontal Flow Wrapping Machine designed for high-speed automated pillow packaging of regular-shaped products. It delivers 40-180 bags per minute with three-servo motor PLC control system, fiber optic sensing, and self-diagnostic capabilities. Ideal for food manufacturers packaging biscuits, bread, chocolate, mooncakes, instant noodles, as well as daily necessities, hardware tools, industrial parts, and boxed vegetables or fruits.
Product Overview
The WS-350 represents Keypack Intelligent (Kunbupack) advanced servo flow wrapping machine solution, combining three independent servo motors with PLC control for superior packaging accuracy and efficiency. This automatic flow packing machine features fiber optic automatic sensing that triggers packaging cycles only when products are detected, entering standby mode when no material is present to conserve energy and reduce component wear. The horizontal packaging machine employs high-sensitivity photoelectric eye color mark tracking with digital input for sealing and cutting positions, ensuring precise bag formation on every cycle.
Temperature control uses independent PID systems to accommodate various packaging materials including BOPP, CPP, PE, and laminated films, making it a versatile chocolate wrapping machine and bread packing machine. The positioning stop function prevents knife sticking and eliminates film waste during production pauses. The simplified transmission system ensures reliable operation with convenient maintenance access, while all control functions are software-implemented, facilitating easy function adjustments and technical upgrades to keep your packaging line current with evolving production demands.
Key Features and Machine Characteristics
-
Three-Servo Precision Control: Three independent servo motors combined with PLC deliver set-and-cut bag length accuracy without empty running or manual adjustment, saving time and reducing film consumption. This servo flow wrapping machine technology ensures consistent bag dimensions across production runs.
-
Intelligent Fiber Optic Material Detection: Automatic sensing initiates packaging cycles only when products are present and enters energy-saving standby mode during gaps, extending component life and reducing power consumption in this automatic flow packing machine.
-
Self-Diagnostic System: Built-in fault diagnosis displays error codes and status information clearly on the HMI, enabling rapid troubleshooting and minimizing downtime for maintenance teams.
-
Digital Color Mark Tracking: High-sensitivity photoelectric eye with digital position input ensures sealing and cutting occur at precise locations on printed film, maintaining brand presentation quality and reducing reject rates for biscuit packing machine and mooncake packing machine applications.
-
Independent PID Temperature Control: Separate temperature zones with PID regulation adapt to diverse packaging materials (BOPP, CPP, PE, laminated films) and varying product characteristics, ensuring consistent seal integrity across production runs.
-
Anti-Waste Positioning Stop Function: Automatic positioning when stopping prevents knife contact with film and eliminates material waste during production pauses, changeovers, or emergency stops, enhancing efficiency of this horizontal flow wrapping machine.
-
Simplified Reliable Transmission System: Streamlined drive system reduces mechanical complexity, improving operational reliability while providing easier access for routine maintenance and cleaning procedures.
-
Software-Based Control Architecture: All machine functions implemented through software enable function adjustments, performance optimization, and seamless technical upgrades without hardware replacement, future-proofing your packaging investment.
