Coating machine control method and coating machine

Abstract

The present invention discloses a coating machine control method and a coating machine. The coating machine control method comprises: arranging a program module by a PLC controller, wherein the program module is used for controlling the pressure applied on a paper seed by a main arm during reel replacing; controlling a high-speed camera to obtain the paper state image of the paper seed during thereel replacing of a coating machine; setting a first line pressure value according to the paper state image, and obtaining the first line pressure value through an operation interface; and controllingthe pressure applied on the paper seed by the main arm within a unit distance according to the first line pressure value through the program module. With the technical scheme, the method and the coating machine can be used for the production of paper seeds with different qualities, can avoid the paper surface festering or even the paper breaking of the paper seed with the poor quality during thereel replacing, and can reduce the economic loss of production enterprises and greatly reduce the production cost.

Description

technical field [0001] The present application relates to the technical field of papermaking, in particular to a coating machine control method and a coating machine. Background technique [0002] In the field of papermaking technology, the coater is the basic equipment of every paper machine and an important guarantee for controlling the surface of paper grades. In the prior art, in order to make the paper product tightly rolled, the main arm of the coater usually needs to exert a large pressure on the paper grade, but the preset main arm pair cannot be changed arbitrarily in the original program of the coater. The pressure exerted by the paper grade. [0003] In the long-term research and development process, the inventor of the present application found that the quality of the current paper grade raw materials is uneven. Therefore, at the moment of changing the roll, the pressure exerted by the main arm is too large, which may easily cause the paper surface of the poor q...

Problems solved by technology

[0003] In the long-term research and development process, the inventor of the present application found that the quality of the current paper grade raw materials is uneven. Therefore, at the moment of changing the roll, the pressure exerted by the main arm is too large, which will easily lead to the paper surface of the poor quality paper grades to fester or even Fault breaks the paper, resulting in the failure of changing the roll, and needs to start the machine again, resulting in economic losses for the production enterprise

At the same time, in the prior art, the water jet roll changing mode is usually used for roll changing. The roll changing speed is about 1600m / min, and the paper web width is about 10 meters. When the equipment is running at high speed, the roll changing time is about 1 Seconds, therefore, the human eye cannot directly judge whether the paper surface is festered or the paper is broken when the roll is changed.
