The three most feared faults of slitting machines are uneven winding, material slitting tendencies (abnormal tension) and inaccurate meter counting. The specific reasons and solutions are as follows:
Uneven winding
Cause: The main reason is that the inner diameter of the paper core does not match or the roller device is not used, resulting in loose winding.
Solution: Replace the paper core that meets the inner diameter requirements, and enable the winding roller to assist in alignment during the winding process.
Material slitting tendencies (abnormal tension)
Cause: Improper winding tension setting causes material deviation or looseness.
Solution: Adjust the winding tension parameters of the slitting machine to ensure that the slitting material passes through the roller and then enters the winding shaft to stabilize the tension.
Inaccurate meter counting
Cause: The meter wheel has poor contact with the feeding rubber roller or mechanical wear.
Solution: Check whether the meter wheel is in contact with the rubber roller at the same time, and manually shake it 5 times to verify the accuracy of the meter; if it is still inaccurate, the meter device needs to be replaced.
Supplementary explanation of other high-frequency faults:
Failure of the correction device (need to check the photoelectric eye settings and material color difference comparison), cutter blunting or offset (need to replace or adjust the cutter), etc. will also significantly affect the slitting efficiency, but based on the frequency mentioned by various sources and the degree of operation impact, the above three problems are more common and directly affect production continuity.
