Abstract

The invention provides a method for automatically adjusting the cutter angle of a transverse cutting machine and the transverse cutting machine. The method for automatically adjusting the cutter angleof the transverse cutting machine comprises the steps that when that the transverse cutting machine works normally by sensing color codes is determined, the cutter angle is adjusted, and normal cutting is achieved; when two adjacent color codes are sensed, a first angle Deg1 and a second angle Deg2 which are stored are not within the range of [ D - mu, D + mu ], and if the absolute value of Deg2-Deg1 is smaller than or equal to mu, the maximum angle adjustment amount which can be conducted by a cutter within a cutting period on the basis of position synchronization is adjusted according to the maximum rotating speed and the maximum torque of a motor; and if the absolute value of Deg2-Deg1 is smaller than mu, the value of Deg1 is modified, Deg1= Deg2, subsequent color codes continue to besensed, and the operation is repeated. According to the method for automatically adjusting the cutter angle of the transverse cutting machine and the transverse cutting machine, the cutter angle of the transverse cutting machine can be automatically adjusted according to the maximum adjustment capacity of the motor, the production speed does not need to be decreased, the production efficiency canbe improved, and meanwhile the workload of operators is relieved.

Description

Technical field [0001] The present invention relates to the field of cross-cutting machines, and more specifically, to a method for automatically adjusting the angle of a cutter for a cross-cutting machine and a cross-cutting machine. Background technique [0002] Usually, the cut material of the cross cutter is coil material. After the previous coil is used up, a new coil needs to be replaced. At this time, there must be joints between the coils. Because of the introduction of joints, the distance between the color code at the end of the previous roll of material and the color code of the head 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 synchronization of the position of the cutting knife and the color code. The above-mentioned cut length refers to the length between two adjacent color marks on the roll material under normal production conditions. The ...
