1, vertically the last dise knife of cut paper will align with the cutting edge of round bottom cutter, and crooked runout phenomenon must not be arranged, and adjustment of the dise knife edge of a knife indulges with the paper of single paper 52 gram/rice that machine is smooth excessively to be as the criterion about it.
2, laterally the flying knife of cut paper and the edge of a knife of bed plate will coincide, and the adjustment in its edge of a knife gap to be rotating rotor with hand, the paper of individual 52 gram/rice are downcut gently be as the criterion.Before using paper cutter, should carry out trial cut earlier.
3, regulate longitudinal cutting device: at first regulate the round bottom cutter to desired location.When mobile, fastening hex nut should be unscrewed, move axially, when changing the round bottom blade, must take off the round bottom cutter shaft from paper cutter, be placed on the platform, withdraw from the taper bolt that tight cutter is used, can take out the round bottom blade as need with hand or wooden mallet.
4, adjust infeed set-up: earlier top cutter screw is unclamped, unclamp nut and bedplate clamp nut again, rotate and regulate bolt, after the both sides nose angle of the rimmer knife on rimmer knife and flying knife and the revolution rotor on the bedplate is aimed at, the screw-driving on trip bolt and the fixed blade, use top cutter screw again, the percent ripple of regulating the edge of a knife is extremely qualified, and nut screwing clamping.
When 5, single cutter wanted to cut any length specification between the 300-1800, under be by the rotating speed of the feeding-in roll constant situation, the different rotating speeds that changes revolution rotor (flail knife roller) reached.Rotate the adjusting handle on the P type buncher, when clockwise rotating, then yardage is also more and more littler, as rotates counterclockwise handwheel, and yardage is just increasing, can be adjusted to needed length like this.Buncher can only be forbidden arbitrarily to rotate handwheel when not starting shooting, in order to avoid roll bad chain at when running start adjusting handle.When rotating handwheel if necessary, should rotate transmission input shaft earlier, rotate adjusting handle again.
6, in the cut paper process, when finding that difference has error between the lateral lattice size,, open the buncher loam cake please referring to the buncher specification, chain in the casing is tightened get final product.
