1. When the cutter is changing the knife, when the blade is lowered to the lowest position (contact with the blade), the switch is closed and the brakes are all stopped.
2. When the old blade is removed from the new blade (or re-grinded), check whether the blade α angle and the shear resistance of the cut material can be basically matched, and then use the wiper cloth to clean the blade from top to bottom. Rub against the blade or along the blade to avoid bumps.
3. Loosen the bolts of the fixed blade and the outside of the knife seat, put the T-screw clamp on the screw hole, rotate the screw clamp to lower the cutter, and make the blade quietly touch the pad and then unscrew the bolt. The cutter handler is screwed into the hole of the cutter and tightened. The knife holder is raised to the original position, the blade is left underneath, and the cutter handles at both ends are pinched with both hands, and the blade is removed and placed on a wooden (or plastic) ) inside the knife box.
4. When changing a new knife, you must pay attention not to make the blade touch any hard things to adhere to the sharpness of the blade.
5. The upper and lower of the tool change should be appropriate, not too high. If it is too high, the knife holder will be released in a corresponding manner. When the cutting is pressed, the knife holder touches the paper, and the cut paper is crushed to form a waste product. When changing the knife, you must only make the blade touch the paper when the paper is cut, and the knife holder cannot touch the paper. Also be aware that the level of blade deepening in the pad (blade) should be appropriate, not too high or too low. High, the paper is not cut through (the bottom sheet presents the joint knife); if it is too low, the paper is pressed into the knife mark after the blade is pressed down, and the paper will be torn under the paper when it is taken out. Sheets or damaged pads, the most serious will even lead to collapse. It is preferred that the normal blade is pressed down in the backing plate to a depth of 0.3 to 1 mm. And according to its length, cut the paper basket completely.
