• Vacuum belt transfer with less wear and high feeding accuracy.

• Automatic air cylinder adjustment for belt tension control, automatic belt loosening when power off prolongs belt lifespan.
• Synchronous transfer of top and bottom high friction needle belt in front section ensures square feeding.
• Auxiliary folding wheel for 2nd time creasing, ensures better formation for 5 ply carton.
• Folding wheels in rear section effectively control sheet folding process and avoid fishtail.
• Accurate speed differential adjustment for top and bottom folding belts reduces scissors error when the carton is formed.
• Motorized folding beam movement for different carton sizes demand

3. Drive unit

• Variable frequency motor driven, synchronizing with printer
• USA Gates timing belt ensures accurate transfer and low noise.
• Out-feeding roller for folded carton pressing, ensuring well bonding. The top out-feeding rollers are rubberized and steel is for the bottom rollers. Conveying gap between top and bottom rollers is motorized with digital readout.
• High-speed jogging system for final carton correction and squaring.

4  Counting and ejecting unit This part realizes high-speed counting and ejecting, and mainly consists of collecting unit, auxiliary collecting unit, collecting table and pushing mechanism.

• Accurate sheets counting with photocell
• Servo motor controls collecting bracket and batching table for accurate sheet batching. Closed-loop control for servo system, ensuring accuracy and lower impact force
• 10~25 sheets per bundle can be pre-set.(Speed/sheets per bundle curve for reference)
• Auxiliary collecting unit ensures enough buffering time for batching at high speed
• Servo driven for conveying rollers and synchronizing with sheet pressing device, brings neat sheets stacking at exit.
• Strong force blower avoids the sheets up-warp, flow direction can be adjusted and flow rate is controlled via variable frequency.
• Rubber cushion is assembled to the backstop, reducing the impact to the carton edge and avoiding damage.

5. Ejecting unit

• Upper ejecting unit can be adjusted front and back with the backstop
• Motorized adjustment of height direction position of upper ejecting unit through lifting device. Upper ejecting unit height adjustment ranges from 100mm to 340mm according to the sheets per bundle.
• Synchronous drive belt for upper and lower ejecting unit without stacking jam.
• Whole ejecting unit can be adjusted left and right to keep the bundle located in the middle of machine
