Detailing Description

Frequency control of motor speed
Adopting frequency converter stepless speed regulation, the acceleration and deceleration smooth control is simple.

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.

Safety shield
Cutter safety shield protection switch can avoid the danger that user forgets to close the shield when machine runs with high speed.

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.

360 °continuous and adjustable longitudinal register device
Button-type 360°continuously adjustable longitudinal register device, equipped with a large speed ratio gear motor, makes registering easier and simpler. 360°longitudinal position registering can be easily done at 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
