4. Die-cutting unit

1. Rubber roller: made of good quality steel, be grinded with chrome plated.
2. Do balance treatment, improve machine running steady
3. Rubber cylinder is separate with die cylinder by air cylinder when no cutting, reduce no-load and prolong blanket use-life.
4. Die roller lift-down automatic by pneumatic control( feed sheets roller go up, stop feeding roller down, make sure correct cutting for every sheets)
5. Rubber roller move 40mm in left and right, wearable average prolong use-life
6. Rubber roller rotates follow die roller by speed compensation device whatever how rubber diameter change, make sure rubber speed same as wooden die, keep cut box is consist with wooden die.
7. Planetary gear structure used for phase adjustment.
8. Phase adjustment by PLC in 360degree with digital input( can be done when run, stop or clockwise or anticlockwise)
9. Machine have repair roller to grind blanket, so it can use many times.
10. Equipped with automatic waste cleaning device, waste paper can be discharged automatically  
11. With slotting knife device,electric auto adjust blade, easy to operate,no need to make wooden die when produce regular cartons.

5.vibration unit
The unit is for removing the waste paper of the carton from die cutting unit
6.Inline automatic folder gluer
The printing slotting die cutting machine is equipped with folder & gluer, which has the advantages of simple structure, high folding precision and beautiful folding.
