Detailing Description

Man-machine interface touch screen
Adopt touch screen and PLC programmable control system, the work condition can be shown real time. Cooperate with the ultra precise double servo motor, the stability can be guaranteed.
Servo control system
Adopt Japanese original Yaskawa servo control system to realize high-speed and precise operation control.
Independent glue coating system
Independent glue coating system, the glue coating system can be run independently after the machine stops, avoiding the glue drying and not easy to clean. The glue tank is glued to the bottom to prevent glue from dripping.
The paper tube forming system
The integral tube forming adjustment structure can be adjusted at the same time on one side or both sides to improve work efficiency, reduce the scrap rate generated by the adjustment process, and save adjustment time and stability of adjustment.

Ink recirculating sealing ink scraper system
With ink closed type ink doctor blade and ensure machine not flying ink in high speed ,so can be circle using ink and keep even of ink color when it is printing.

Large diameter ceramic anilox roller
Adopt 120mm larger diameter ceramic anilox roller to driven ink ,big diameter moving ink touch big area ,moving ink much stable ,ceramic anilox roller high precision ,and can be high precision for printing effective and clear pictures in details ;Ceramic dot detail, clear ink, high speed dot rate, screen printed layered, stronger.
