The high speed coater is used for the coating production of BOPP sealing tape. The roll of the substrate is coated with a layer of glue, paint or ink of a specific function, and dried to be wound up. It adopts a special high-speed coating head, and the gravure printing machine can effectively reduce the generation of air bubbles. The high-speed coating machine is equipped with a full-speed automatic film-adjusting mechanism and a tension closed-loop automatic control.
There are two types of high-speed coating machines, one is to apply an emulsion on the screen by a plurality of wet-wet operations, or to add a drying process after each coating. A machine for metering a liquid (or melt) polymer material such as a binder or a coating on a surface of a material.
The automatic high speed coater for screen printing works the same way, but its performance varies according to different models and different manufacturers. The screen high speed coater is provided with a device capable of clamping the frame on the vertical frame. The front and rear of the screen area is a horizontal coating mechanism consisting of a coating tank and mechanical or pneumatic components that control the angle and pressure of the coating tank.
Both ends of the high-speed coating mechanism are mounted on the vertical support arm of the high-speed coating machine, and the high-speed 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 coater, and some models can also be loaded into the screen from the side. In models designed for large format frames, side mounting is more common because the frame is large and bulky, and the side loading allows for a smaller amount of lift and movement. When the automatic screen high speed coater is operated online with other automatic screen processing equipment (such as cleaning equipment, recycling equipment, drying equipment and developing machine); it is more convenient to mount 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. In order to make the operation more convenient, many models have pedals to control the folder movement, and the operator can free up his hands to control the screen. After the screen is installed and the corresponding high-speed coater is filled with the corresponding emulsion, 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.
The high-speed coating machine manufactured by Jiangyin Lida Printing and Packaging Machinery Co., Ltd. has an excellent position in China and is a domestic high-quality coating machine manufacturer.
