Detailing Description

Man-machine interface touch screen
Adopt touch screen and PC control system, the work condition can be shown real time. Cooperate with the ultra precise servo motor, the stability can be guaranteed.

Automatic counting system
The machine has automatic counting system. The user can set a number to count. When bag quantity meets the number, the bag will be jumped out like the picture shows.

Automatic glue supply system at the bottom
Automatic glue supply system is adopted for glue coating at the bottom. If the amount of glue in the glue tank is insufficient, the glue will be supplied automatically. When the machine stops, the rubber roller will run automatically to avoid glue solidification after the machine stops.

Color Mark Tracking System
Precise color mark tracing system can make sure precision of bag printing pattern cutting position. The color mark tracing function can avoid the readjustment after paper reel changing, paper web breaking, or power outage. The machine can stop automatically when the color mark is error. It will save time and reduce the waster rate.

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
