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 three servo motor, the stability can be guaranteed.

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

High speed servo puncturing system
The High speed servo puncturing system pre-cut the material by the tooth knife. It make the bags more pricision, evenly and beautiful. It could be used for more materials.

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.

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.
