9.1 Technical parameters:




Minimum Paper Spacing: 130/256;




Minimum pressure line spacing: 130 mm; 5 knives 8 lines; compressible convex to flat, convex to concave two lines, the width of concave and convex line is 12 mm and 16 mm.




9.2 Materials and other requirements:




9.3 Before each adjustment, the fasteners of the machine should be checked to be firm; the guide rails, screw rods, hexagonal bushes, rolling bearings and other parts of the cutter wheel, press wheel should be checked to be clean and lubricated.




9.4 After checking correctly, turn on the power supply, hit the "manual and automatic knob" of the cabinet production to the manual position, check the knife wheel manually, press the wire wheel locking and loosening.




9.5 Manual inspection of cutter wheel grinding system, grinding wheel position must be appropriate, and inspection of lubrication system, must be intact.




9.6 Safe operation and precautions




(1) When the inspection machine moves, it should be able to move left and right.




(2) During the operation of the machine, people are not allowed to approach the cutter wheel so as to avoid injuring people by rotating the blade.




(3) When the machine stops, the waste paper on the machine should be cleaned up.




(4) The machine must be cleaned and maintained at least once every shift, especially the guide rail part, and no debris should be left.




(5) Replacing thin blades, pressing wheels, grinding wheels and other items must be shut down.




(6) With the decrease of blade wear and diameter, the cutting knife must be adjusted downward, and the size of cutting edge through cardboard should be in the range of 3-5 mm.




(7) When replacing the blade, care must be taken to injure or damage the blade. Before the new blade is put on, the cutter head, the blade and the veneer of the pressing plate should be cleaned. The tightening degree of the pressing screw on each cutter head shall be the same, and the screw thread shall not be damaged. After the blade is pressed, the radial and axial oscillation of the blade should be checked. When the blade is running at high speed, it is forbidden for people to stay or move on the front of the blade.




(8) After replacing the grinding wheel, the inclination of the two grinding wheels should be checked to be the same, and the grinding edge should not deviate from left to right.




(9) On the premise of accurate positioning of the machine, if there is still a difference in the size of the cardboard rolling cover, the knife should be checked to see if the positioning datum of the line is consistent. The positioning datum of the cutter line is the central axis of the machine. After the datum line of the cutter line is coincided, the equipment is corrected.
