Product Highlights
Paper Pressing Wheel Assembly
- Gear-driven dual-power transmission on upper/lower wheels delivers exceptional stability during paper conveyance, particularly with corrugated paper.
Glue Distribution System
- Dedicated servo drive simplifies transmission and maintenance.
- Entire unit slides out for cleaning.
Box Collection Unit
- Fish-scale collection structure with weighted rollers enhances film-box adhesion.
Highlights Paper Feeding System
- Features optimally stable separation blades with zero wobble when locked, ensuring superior paper separation.
- Single-plate feeding belt simplifies maintenance and replacement. Linear bearings enable smooth front/rear movement of the paper pressing mechanism; pneumatic vibration motors reduce noise and optimize vibration.
Gluing System
- Independent servo drive allows parameter input via HMI without wrenches or phase adjustment.
- Hard-anodized aluminum alloy glue rollers offer lightweight and high hardness.
- Optimized program with glue sensor enables automatic activation with product presence, separation without product, and jam alarm/shutdown.
Pusher Claw System
- Linear guide fixation eliminates vibration (vs. linear bearings), ensuring stable paper feed.
- Patent-certified synchronous belt drive provides quiet operation, stretch resistance, oil-free performance, low noise, and sustained precision.
- Front/rear adjustable press wheels adapt to product positions; side-fixed design simplifies setup. Side guides synchronize with claws to reduce adjustment frequency and time.
Film Forming Section
Dual-servo drive technology (patent-certified) integrates film
feeding, horizontal creasing, punching, print registration,
vertical creasing, and cutting for precision forming.
- Film Feeding Unit: Dual linear guides prevent swing arm deviation; PLC-controlled motor runs continuously during start/stop; heating optional for films ≥ 0.25 mm.
- Horizontal Creasing: Linear module + stepper motor (smooth high-speed operation, easy maintenance).
- Punching Unit: Cylinder-driven metal mold; front/rear adjustment (linear guides + rack-and-pinion); left/right adjustment (linear guides + ball screws).
- Print Registration: Precise adjustment of printed patterns.
- Vertical Creasing Unit: Vertical adjustment (linear guides + eccentric blocks); horizontal adjustment (guides + ball screws).
- Cutting Unit: Cylinder-powered spring-compressed blades for quick adjustment.
Lamination Section
- Front positioning: Two cylinders + four bearings + positioning block (bearings contact belt, block suspends to protect belt).
- Side positioning: Conventional guides or invention-patented push gauge.
- Pneumatic double-pressing sequence: Boxes positioned → film extended → belt stops → pressed/cut → system reset.
Electrical System
- INOVANCE components (China’s top-tier brand) with bus-based control ensure efficient, stable operation and simplified maintenance.
