Abstract

The invention provides a method for automatically adjusting the angle of a cutting knife for a cross-cutting machine and the cross-cutting machine. The method for automatically adjusting the angle of the cutting knife for the cross-cutting machine includes: when the cross-cutting machine is confirmed to be working normally by sensing the color mark, the angle of the cutting knife is adjusted to achieve normal cutting; when two adjacent Neither the stored first angle Deg1 nor the second angle Deg2 at the color scale is within the range of [D‑μ, D+μ]. If |Deg2‑Deg1| The torque-driven knife roller adjusts the maximum angle adjustment that the cutter can perform in one cutting cycle on the basis of position synchronization; if |Deg2-Deg1|>μ, modify the value of Deg1 so that Deg1=Deg2, And continue to sense subsequent color marks and repeat the above operations. The invention can automatically adjust the cutter angle of the cross-cutting machine according to the maximum adjustment capability of the motor, without reducing the production speed, can improve the production efficiency, and at the same time reduce the workload of the operator.

Description

technical field [0001] The invention relates to the field of cross-cutting machines, and more specifically, to a method for automatically adjusting the angle of a cutting knife for a cross-cutting machine and the cross-cutting machine. Background technique [0002] Usually, the cutting material of the cross cutting machine is coil material. After the previous roll is used up, a new roll needs to be replaced. At this time, there must be joints between the coils. Because of the introduction of joints, the distance between the tail color code of the previous roll and the head color code of the next roll is no longer the standard cut length. In this case, it is necessary to reset the angle of the cutting knife of the cross-cutting machine to restore the position synchronization of the cutting knife and the color mark. The above cut length refers to the length between two adjacent color marks on the roll material under normal production conditions. The above-mentioned positio...
