    · We offer most rubber roller optional that expert to meet various paint, board material and coating effect.

    · According to different coating thickness demands, you can choose single, double, three or special roller structure.

    · Configuration also flexible based on standard machine, customized function is able to design and come true.

  • Roller quick disassembly

    Each rubber roller connect to the motor by NSK bearing with ceramics protective shield. Design quick disassemble structure that convenient to repair or change.

  • Dovetail groove roller lift

    The roller apply dovetail groove structure lifting instead of screw drive structure, roller lifting controlled by electric button that stably and easily. Assist by hand wheel ensure more accurate.

  • Push screw compensator

    When push the gap between the application rubber roller and doctor steel roller, this screw compensator device can easily adjust balance to ensure the whole gap keep the same.

  • Roller scraper

    Sweden thin scraper blade with good flexibility that can remove any impurity and keep even paint on roller during work, uniform screw on the grip ensure stable blade and adjust accurately.

  • Electric motor and reducer

    Each roller driven by independent electric motor which stable and durable, with double worm gearing reducer that translate power more smooth and accurately to the roller rotate.

  • Low voltage apparatus

    All the electrical low voltage apparatus concentrate orderly and clearly inside the bottom of machine body, far away from working influence and easily to check or maintenance.

  • Two different paint recycling

    UV putty filling and primer coating with two independent paint recycling structure and its own paint pump that can work together or separately.

  • Thickness detector

    While the thickness of boards over too much than set data, the sensor at the feeding entry will detect and stop the conveyor immediately in case of harm rubber roller.

  • Paint heating container

    Warm UV paint get better coating effect, this stainless steel container with temperature controller heating water around 50℃ and keep the liquid recycling UV paint as best situation.

  • Roller water heating system(Option)

    In some cold environment, consider add water heating system heating the doctor steel roller keep UV paint warm on the roller for recycling coating, increase the coating effect a lot.
