Precautions for Using the Printer Cutter During Use
The flatness and smoothness of the trimming edge of the trimmer depends on the blade sharpening angle, the sharpening quality and the degree of passivation of the blade edge. The blade angle is generally around 19°. When cutting harder paper, the blade angle should be larger.
Each time the knife edge is sharpened, it must be cooled sufficiently to avoid knife edge annealing. In order to make the knife edge sharper and smoother, the knife edge is finely ground before applying it. When cutting, apply soap or paraffin regularly on the knife edge to extend the durability of the knife and make the trimmings smooth. If it is found that there is a paper-drawing phenomenon in the trimming edge of the cutting material, the edge should be repaired or resharpened with oilstone at any time.
Due to the use of a high-efficiency flat-enveloping hourglass worm gear reducer, the self-locking worm gear reducer itself is not self-locking, and the main motor is stopped. After the cut-out switch of the switch knife is pulled to the tool change position, the drive has lost the brake, and the safety device has lost its protection. When the bed is in a stationary state, it may be slipped, which may seriously endanger the safety. Therefore, in this state, it must be confirmed that the knife bed is reliably stopped and the following operation can be performed when the wooden pad is placed under the blade.
To change the cutter, first turn off the main motor, wait about 2 minutes, and confirm that the drive belt is completely stopped, place the two wooden tool changers under the blade, and place the switch selection switch on the switch panel. The tool change position and the tool bed function selection switch must be in the cutting position. Use the sleeve to rotate the pulley face nut, remove all the connecting screws on the blade, and then use the internal hex wrench to push the hanging knife device inward to about 4 mm to make the hanging knife device. The brake was disengaged, and the rotary knife device was used to place the blade smoothly on the two wooden tool changers. Two tool change handles were installed and the blade was removed. Care was taken to hold the blade against overturning and injuring others.
