Advantages & Features
-
Patented High-Speed Silent Servo Synchronous Mould Drive — Equipped with a servo-driven synchronous wheel operation device that ensures high-speed, low-noise performance. The mould positioning device enables quick and accurate changeovers, reducing downtime to 10–120 minutes depending on mould size, significantly improving production flexibility.
-
Large-Format Material Handling with Precision EPC Control — Supports feeding widths up to 1450mm and rewind diameters up to Φ1200mm, with an integrated edge position control (EPC) system for accurate material guidance. Recommended for 100–140gsm hard non-woven fabrics, ensuring optimal folding results even at maximum side width of 350mm.
-
Multi-Functional Bag Forming Line with Ultrasonic Sealing — Combines bag mouth indentation, handle loop folding, cutting, punching, sealing, and main ultrasonic molding in one continuous process. The system also includes side folding, collection, and counting stations, enabling fully automated production from roll stock to finished bag.
-
Versatile Ultrasonic Module Configuration — Features multiple ultrasonic units tailored for different tasks: main sealing (15kHz, 350×90mm), embossing (20kHz, 25×60mm), and circular sealing (20kHz, Ø55mm), delivering strong, consistent bonds on laminated non-woven materials including BOPP film and aluminized film.
-
Flexible Bag Size Adaptability — Accommodates bag heights from 200–500mm, widths from 110–550mm, and side widths from 80–350mm, with three typical size references (e.g., 500×550×350mm, 390×230×80mm). The machine’s design allows for rapid size changes via modular adjustment mechanisms.
-
Integrated Servo Motion System for High-Precision Operations — Employs multiple HUICHUAN servo motors across key stations including mould drive, ultrasonic power, bottom take-bag, puncher movement (vertical & parallel), pulling non-woven, and side insertion. This ensures synchronized, precise, and stable motion control throughout the production cycle.
-
Comprehensive PLC-Based Control with Touchscreen Interface — Powered by Panasonic main PLC and dedicated controllers for handle loop and bag collection, all managed through Weinview touchscreens. Real-time color marker tracking (Italy-made photocell) ensures accurate register control, while the system supports easy parameter adjustments for different bag specifications.
-
Dual-Drive Bag Opening and Positioning System — Utilizes a combination of step motors for opening, sealing cutter positioning, and corrective actions, ensuring precise bag mouth formation and alignment. The hot scalding rotary and cutter positioning further enhance sealing consistency and edge quality.
-
Robust Mechanical Build with Complete Auxiliary Support — Features a heavy-duty frame (overall size 9600×7300×2700mm, total weight ~12000kg), complemented by a full set of pneumatic cylinders, air compressor connection diagram, and an extensive spare parts kit (including tools, heating tubes, thermocouples, timing belts, springs, and fans) for easy maintenance and long-term reliability.
