Working principle of hot melt adhesive coating machine and automatic coating machine

Operation and coating quantity control of combined scraper coater:

(a) the structure of the combined scraper coating head and the application of soft and hard scrapers. The structure of the combined scraper coating head: the components of the combined scraper coating head are shown.

The characteristics and functions of the combined scraper coating head: the scraper coating is controlled and operated by adjusting the Angle of the scraper. But the combined blade is complemented without changing the Angle of the blade. The characteristic of only changing the pressure load of the scraper to control the amount of coating. This will help to prevent blade marks or coating quality problems when changing the amount of coating. This is especially important when applying low quantities. In order to change the pressure load on the tip of the scraper, the clamping beam equipped with the scraper is moved in or out on the guide rail. But do not change the scraper pressure bracket position.

The working principle of hot melt adhesive coating machine and automatic coating machine is the same, but its performance is different according to different models and different manufacturers. The screen coating machine is provided with a device that can clamp the net frame on the vertical frame. Before and after the screen area is the horizontal coating mechanism, the hot melt adhesive coating machine by the coating groove, and control the Angle and pressure of the coating groove of mechanical or pneumatic components.

The two ends of the hot melt adhesive coating machine are installed on the vertical support arm of the coating machine. Through the transmission of belt, chain or cable, the hot melt adhesive coating machine moves up and down, coating along the surface of the screen. The transmission mechanism is connected to the servo or frequency conversion motor, so that its operation is stable and fine. Ensure the position of the control coating mechanism.
