Abstract

The invention is suitable for the field of rewinders and provides a rewinder material thickness calculating method which comprises the following steps: enabling a system to obtain the number N of turns of a rewinder through a sensor; utilizing N to obtain the deviation value Delta N of the number N of turns, calculating the deviation length Li within the unit time according to the coiling diameterof the current shaft, the mechanical transmission ratio parameter K and the deviation value Delta N, and carrying out superposition of Li on the system length deviation Ls; according to the system length deviation Ls, calculating the length deviation difference Delta LS of each shaft within the unit time, and calculating the coiling diameter Dn of each shaft; and according to the coiling diameterDn, calculating the area difference Delta S within the unit time, and calculating the material thickness d according to the area difference Delta S and the length deviation difference Delta LS. According to the rewinder material thickness calculating method, manual operation is simplified, the manual operation time is shortened, the reliability is improved, and the situation that the material thickness is not uniform, the thickness is not easy to measure and the thickness cannot be manually set is avoided.

Description

technical field [0001] The invention belongs to the field of rewinders, and in particular relates to a method for calculating the material thickness of a rewinder. Background technique [0002] In the prior art, the material thickness of the rewinding system is manually set. The advantage of this approach is that the software design is simple. But the shortcomings are also very obvious. First, the operator is required to understand more operational knowledge, which increases the workload of the operator. Second, in the case of uneven material thickness, manual setting is not advisable, because during the operation of the equipment, the material thickness changes randomly, and manual modification cannot be performed quickly and accurately in real time. Third, during the operation of the equipment, due to various reasons, the material will undergo a certain amount of deformation, resulting in an error between the set thickness and the actual thickness. Fourth, the thicknes...
