According to the relationship between the coating machine and the paper machine, the coating operation is divided into machine-in type and out-of-machine type: according to the number of coatings, it is divided into single-layer coating and double-layer coating: in-machine coating is a coating on the paper machine The cloth machine enables papermaking and coating to proceed continuously; double-layer coated paper has better printability than single-layer coated paper and can improve the quality of coated paper.
There are two coating methods, one is to coat the photosensitive emulsion on the screen through multiple wet pressing operations; or to add a drying process after each coating. A machine that quantitatively coats liquid (or melt) polymer materials such as adhesives or coatings on the surface of the material.
The two ends of the coating mechanism are installed on the vertical support arms of the coating machine, and the coating mechanism is moved up and down through the transmission of belts, chains or cables to coat along the surface of the screen.
The transmission mechanism is connected to the servo or frequency conversion motor to make its operation stable and to accurately control the position of the coating mechanism. Before coating, load the clean and stretched screen from the front of the coating machine. Some models can also load the screen from the side.
When the automatic screen coating machine is running online with other automatic screen processing equipment (such as cleaning equipment, regeneration equipment, drying device and developing machine), it is more convenient to install the plate from the side.
