What is the coating principle of the coating machine for nonwoven

- Jul 01, 2019-

The coating machine for nonwoven is provided with a device capable of clamping the frame on the vertical frame, and the front and back of the wire mesh area is a horizontal coating mechanism, the coating mechanism is coated by the groove, and the angle of the coating groove is controlled. It consists of mechanical or pneumatic components.


The coating mechanism of the coating machine for nonwoven is installed on the vertical support arm of the coater, and the coating mechanism is moved up and down by the belt, chain or cable transmission, and coated along the surface of the screen. The transmission is connected to a servo or variable frequency motor for smooth operation and precise control of the position of the coating mechanism.


Before coating, the clean, stretched screen is loaded from the front of the coating machine for nonwoven, and some models can also be loaded into the screen from the side. Regardless of how the screen is installed, once the screen is in the correct position, the pneumatic clamp or mechanical clamp is closed and the screen is locked.


After the screen is installed and the corresponding emulsion is poured into the coating machine for nonwoven, the coating can be started. Depending on the function of the control system and equipment, the equipment can simultaneously coat both sides of the screen. There are two coating methods, one is to apply the emulsion on the screen by a plurality of wet-wet operations, or to add a drying process after each coating.
