1, covering the working principle of the machine:

Simulation of manual veneer action, using a variety of molding pressure wheel. The appearance of decorative materials attached to the surface of the substrate, the general choice of profile centerline or the highest point or the lowest point as a starting point, the pressure roller profile along the profile, point by point, in order to fix the position, the profile of the profile envelope. When the profiles according to the transport direction of movement, has been coated decorative materials through the pressure roller, molded wheel by-point rolling, to achieve the composite work of the two. The yarn (cotton, wool, linen, silk, silk, etc.) coated in the core yarn (spandex or other forming a covering yarn for weaving or knitting purposes.

2, the mechanical type of coating machine:

Universal covering machine is generally divided into two types of cold glue and hot glue.

There are two ways of coating and roller coating. Volatile Solvent Glue Use Scratch-On, 1 Glue-Coater Apply Liquid Glue. Liquid glue can be divided into solvent glue and water glue. Plastic tank is easy to seal, to prevent coating plastic volatilization. Water-based plastic and volatile small solvent plastic generally use roller coating, easy to operate.

Use solid glue, 2 hot glue coating machine. Cladding hot plastic box after heating and melting use, the general coating glue heating temperature is about 220 ℃. Suitable for solid wood veneer and decorative paint paper.

3, covering machine materials

Can have grooves, curved surfaces, 1 Substrate: Moldings, MDF, WPC, PVC, aluminum profiles and other lines. Substrate requirements: for the regular line profile. However, each point must be straight for the longitudinal direction, with a certain pressure resistance, the length is generally more than 40 cm to infinity. Generally less than 50 centimeters, such as 300 Universal Coverage most wide film width of 30 cm. General roll use. 2 veneer material: PVC decorative film, decorative paper, wood veneer, Boeing board, aluminum composite film. The width depends on the substrate needs and the model chosen.
