1.3)Knife adjustment
Every time install the new knife, or old knife grinded, adjust the height of knife
bed by manual in order to adjust the cutting depth of the knife. To avoid the new
knife replaced causing accidents because of deep cut due to big height.
To determine the depth of cutting: Manually pull the knife locking handle(Picture
1,11),press the two hands cutting button,and stop the knife bed in the lowest
position after one circle of cutting , Then observe if the cutting depth is
piston rod
normal(the normal cutting depth is about 0.5~1mm 0-1/64″~0-3/64″) . If the depth is not reasonable,
bed height on the left side of the piston rod can be adjusted in the picture the edge of the sword;If
the blade only touch the knife at one side,you can solve it by adjusting the hex screw of the knife
eccentric shaft in front of the machine(Picture 1,4).
When the blade wears about 12 to 15 mm(0-15/32″ to 0-19/32″), you should use the second row of screws
hole in the blade. If the blade is worn and unusable after using the second row of screw hole , the
blade should be changed. When changing the new blade, Put a new blade should be tuned the piston

rod to the highest position. Note 1:After adjusting the knife, the knife locking handle should be adjusted to the original position. Note 2: when the blade wear, adjust the knife bed height (piston rod) first, and then the knife bed eccentric shaft, and finally the knife bed delay time in a computer.
3).Adjustment of paper impeller The adjustment of the verticality between the paper push side and working table surface is achieved by adjusting the screw(3).Before adjusting, please little loosen the bolt M6*30(4) and screw M5*15(6), then rotate the screw clockwise to lift the end of paper impeller, the angle between the paper push side and working table surface reduces; anti-clockwise rotates,the angle expands.After adjustment, you should hold the screw first and fix the bolt M6*30(4) firmly, and then lock the two screws M5*15(6). The back limit of paper impeller is controlled by limit switch,front limit is controlled by PLC.
