Control method of banknote bundle pre-bundling mechanism for intelligent cash processor

The invention provides a control method of a banknote bundle pre-bundling mechanism for an intelligent cash processor. The method comprises the following steps that a control system compares recordedpre-bundled film consumption lengths, calculates and balances consumption of two rolls, controls an upper tape reel mechanism and a lower tape reel mechanism to rotate correspondingly according to calculated values, and particularly, measures the unwinding length of a plastic film according to the rotating distance of a coded disc. The control system calculates a correction coefficient value for leveling to ensure that the consumption quantities of two rolls of plastic films are consistent according to the unwinding quantities of the upper tape reel mechanism and the lower tape reel mechanismmeasured by the coded disc, so that the upper tape reel mechanism and the lower tape reel mechanism are ensured to reduce large and small rolls, consumables can be uniformly used, the replacement frequency is reduced, and the
