The use and maintenance of ultra-thin knife slitting line

August 22, 2021

When using, first carefully check whether the fasteners are loose, whether the power valve leaks, whether the various operating keys are sensitive, then lubricate the lubrication parts, thin knife drive gear coated with high temperature resistant calcium grease, and then according to production requirements Adjust the knife line.

Here we must pay attention to adjust the knife gap, the slitting blade should be lifted away before moving, and do not interlock, otherwise it will easily lead to blade deformation or damage the blade. After the knife position is adjusted, the blade is slowly put into position, the depth is 3~5mm, the blade must be in the centerline, can not be deviated, the two can not contact, otherwise the blade and the s Burned out. The adjustment of the guide roller should be on the same line as the indentation line, and the feed positioning baffle should be fastened and parallel to the side edge of the device. Otherwise, the cut cardboard may be easily deflected, causing extra wheel marks. After everything is in order, confirm the correctness and then manually drive the wheel. If there is no abnormality, turn on the power and turn it on.

After the thin blade machine is used for a period of time, it is necessary to re-tighten the fastening screws. In particular, the screws fixing the blade must be inspected frequently, otherwise the blade may be damaged or the flying blade may hurt. The grinding wheel must also be adjusted in time so that it will be in close contact with the blade when it is sharpened. When the thickness of the grinding wheel is less than 2mm, the new grinding wheel must be replaced. When the outer diameter of the blade is less than 225mm, it must be replaced. The service life of the blades and grinding wheels depends on their quality, the number of papers, and the quality of the paper. When selecting a good quality brand and a reputable supplier, the purpose of cost savings and product quality improvement can be achieved.

Second, common fault analysis

1. Difficult start or unable to start

1 lack of voltage; 2 power supply phase loss; 3 circuit fuse blown; 4 motor has been broken; 5 drive wheel fixed key off; 6 drive gear into the foreign body stuck; 7 have bearing damage or knife gap adjustment is too narrow, the blade is card.

2. Automatic shutdown.

1 Power failure; 2 Incorrect adjustment of the frequency range of the inverter; 3 The wheel suddenly drops off; 4 The computer input is incorrect.

3. The grinding wheel can't move freely.

1 Inadequate air pressure; 2 Damaged solenoid valve; 3 Damage to the cylinder that controls the lift of the grinding wheel, or the loose spring of the traction return; 4 The grinding wheel is stuck too tightly to the blade, which is caused by incorrect adjustment of the grinding wheel.

4. Suddenly the machine noise increases and there is rhythm vibration.

1 Loose fasteners; 2 Drive gear fly into paper edge.
