The flatness and smoothness of the cut edge of the cut object depend on the blade sharpening angle, the sharpening quality and the degree of passivation of the blade edge. The blade angle is generally about 19°, and the blade angle should be larger when cutting harder paper.

　　Each time the edge is sharpened, it must be cooled sufficiently to avoid annealing the edge. In order to make the knife edge sharper and smoother, the knife edge should be finely sharpened with whetstone before use. When cutting, soap or stone wax should be applied frequently to the edge of the knife to prolong the durability of the cutter and make the cut edge smooth. If you find that there is a paper pulling phenomenon on the cutting edge of the cutting object, you should use whetstone to trim the edge or re-sharpen the blade edge at any time.

　　Replacement of the cutter

　　Due to the use of high-efficiency flat bread torus worm reducer, which itself is not self-locking, the main motor stops, the cutter cutter selection switch is pulled out to the tool change position, the transmission has lost the brake, the safety device has lost protection, and the tool bed has the possibility of sliding down in a stationary state, which may seriously endanger safety.

　　When changing the cutter knife, first turn off the main motor, wait for about 2 minutes, and confirm that the transmission belt is completely stopped, put two wooden cutter changers (provided by the manufacturer) under the blade, put the cutting switch cutter selection switch on the switch panel in the tool change position "", the cutter bed function selection switch must be in the cutting position, rotate the pulley end face nut with the sleeve, remove all the connecting screws on the blade, and then use the Allen wrench to push the hanging knife device inward for about 4MM to make the hanging knife device brake detached, The rotating knife hanging device makes the blade fall smoothly on the two wooden knife changers, install two tool changer handles, remove the blade, and pay attention to holding the blade to prevent it from tipping over and hurting people.

　　Remember: 1. Confirm the purpose of the operation, do not press or mismove the button.

　　2. Do not put your arm under the knife bed and paper press

　　Install the cutter

　　First, confirm that the main motor start button is in the stopped state, and confirm that the main motor pulley is stationary, install the sharpened blade on the tool changer, and then push the tool changer and blade together with the blade to the blade in front of the paper press, and place the cutting switch tool selection switch (Fig. 3.5) at the right end of the tool change position. , rotate the knife hanging device according to the method mentioned above, raise the blade to the highest position, install the blade connection screws and tighten them, then unscrew the two handles on the tool changer, remove the tool changer, install the rest of the blade connection screws and tighten them;

　　Adjustment of the cutter

　　Every time a new blade is installed, or the old blade after sharpening, the height of the tool bed should be manually adjusted to adjust the cutting volume of the blade, so as to avoid accidents caused by deep cutting caused by the large height of the new blade.

　　The adjustment steps are:

　　(1) Make sure that the paper cutter is in the tool change state, first stop the main motor, press the main motor stop button, confirm that the main motor is in a stationary state, and then put the cutting cutter selection switch in the middle tool change position.

　　(2) Determine the cutting depth of the blade: use a socket wrench to rotate the nut on the end face of the pulley to make the tool bed move to the lowest point, and observe whether the depth of the blade cutting into the cutting strip is reasonable (normal cutting 0.5-1 mm).

　　If the cutter edge is in contact with the knife bar at only one end, it can be solved by adjusting the eccentric shaft behind the main frame.

　　If the blade is worn and cannot cut through the paper, the blade should be moved down in the direction of the long hole until it can completely cut the paper.

　　The specific adjustment method is as follows: turn off the main motor and power switch, loosen all the blade connection screws, put the tool bed at the lowest point in a manual way, use the Allen wrench to push the hanging knife device inward by about 4MM, so that the hanging knife device brake is disengaged, and rotate the top knife cam to make the blade cut off the paper.

　　Warning: 1. When the depth of the cutter is adjusted, the main motor cannot be started.

　　2. The top knife cam can only be fine-tuned, if the adjustment range is too large, the brake of the hanging knife device must be disengaged, otherwise it will cause damage to the hanging knife device!

　　When the blade is worn about 20-25mm, the second row of screw holes under the knife should be used, and 2 top cutter blocks (random accessories) should be added to the end face of the blade (blade figure 4-M5). When the blade is worn out again to the point of being unusable, it should be replaced with a new one.

　　The blade and the tool bed must be properly connected and not installed arbitrarily, and the new blade should be installed in line with the blade and the first row of screw holes on the right side of the tool bed.

　　Note: Before the new blade is installed, the edge chamfer must be trimmed according to the blade diagram, and the hole spacing size should be according to the manufacturer's knife size.
