Working principle of coating drum Composite Machine and matters needing attention

Date:2021-01-12
Info:
 The working principle of the coating drum Composite Machine is to heat the hot melt adhesive box fi

  The working principle of the coating drum Composite Machine is to heat the hot melt adhesive box first, and guide the paper or other base materials according to the routing direction shown in the figure. When the hot melt adhesive box is heated to the set melting point temperature of the hot melt adhesive, the hot melt adhesive is melted, and the melted adhesive is pressed into the coating die through the hydraulic system.

Composite Machine

  Then, the coating die head is placed on the substrate, and the hot melt adhesive is sprayed on it. At the same time, the drive motor is started, and then the pressing roller and the composite roller are pressed together, and adjusted to the appropriate pressure;

  The flatness of the substrate can be adjusted by adjusting the position of the deviation adjusting roll; the traction tension of the substrate can be controlled by adjusting the tension of the clutch and brake, so that the machine can run smoothly, so as to achieve good coating composite quality and effect.

  According to different machine design, there are roller coating and scraper coating in compound gluing. There are also differences between the surface of the cloth coated with glue and the surface of the cloth or the surface of the film. Different ways of gluing make the situation of penetration and film formation of glue on the substrate different, and of course, the effect is also different.

  The presence or absence of the grain on the coating wheel and the pattern of the grain will also affect the difficulty of carrying glue and the form of glue coating. The coating wheel with special texture and corresponding glue can even produce high-performance finished products, such as air permeability, super soft handle, etc. Compound need to pay attention to the amount of glue, pressure, glue temperature, glue opening time, winding, unwinding tension.
