  Detailing Description

Helical gear transmission structure
Whole machine adopt helical gears driven much stable running ,can reduce the gears gap moving to cause the printing effective ,High Harden Gears ,Increase the long life of gears ,reduce the gears using time ,ensure long time use and constant precision

 

 

 

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

 

 

360°continuous and adjustable longitudinal register device
Button type 360°continuous and adjustable longitudinal register device, equipped with high speed than a right angle gear motor, registration easier and more simple, 360 ° vertical position alignment, any location easy to get the touch of a button

 

 

 

Independent group automatic ink system
Independent group automatic ink system, avoid stopping too long after drying of the ink roller outlets blocked, affecting print quality, ink system will automatically turn on when the machine stops, can be opened one or more sets of ink

 

 

 

Independent ink circulation system
Independent ink circulation system to ensure that the ink cartridge always has enough ink supply, ink viscosity always consistent. Avoid the ink cartridges do not have enough ink and ink drying lead to loss of print.
