Nikka K-V Sprayer

Key Features & Design

The K-V Sprayer utilizes a specialized triple-roller construction to control powder application precisely:

  • Triple-Roller System: The design includes a Hopper for powder storage, a Spray Roller for dispensing, and a unique Anti-scattering Roller.
  • Precision Coating: A Doctor Blade applies pressure to the spray roller surface to ensure a uniform powder coating.
  • Corona Discharge Technology: Uses a Discharge Cable to generate a corona discharge that separates and disperses powder from the roller surface onto the web (film).
  • Digital Control: Features a Touch Panel operation panel for integrated control and a High Tension Monitoring System to track electrical currents.
  • Safety Sensors: Includes a Tension Detector that sounds an alarm if the discharge cable becomes loose or is cut.

Operational Efficiency

The K-V Sprayer is engineered for high-speed performance and minimal maintenance:

  • Enhanced Adhesion: By limiting the spraying space to a 2mm gap between the anti-scattering roller and the web, the system dramatically increases powder adhesion.
  • High-Speed Performance: The true value of the system becomes more apparent as line speeds increase.
  • Visual Cleanliness: Powder dust in the air is “almost impossible to detect” by visual inspection during operation.
  • Adjustable Volume: Powder volume can be controlled in 1% increments via the touch panel and can reach capacities twice that of the previous K-III model.
  • Easy Maintenance: The system retains the same fundamental spraying principles as previous models, ensuring maintenance remains simple for operators.

Cost Benefits

The system provides several economic and quality-related advantages for manufacturing facilities:

  • Reduced Material Waste: There is a “sharp reduction” in the consumption of powder due to more efficient adhesion.
  • Lower Cleaning Costs: Minimized powder dust and contamination lead to “less cleaning requirements” for the factory environment.
  • Improved Product Quality: The elimination of unexpected powder dropping and contamination leads to an overall increase in product quality.
  • Factory Environment: Contributes to factory environment improvement by keeping the air clear of powder dust.
