YT350 PUR lamination machine for WPC door profile

YT350 PUR lamination machine for WPC door profile

Hot glue lamination machine is a mechanical device used to paste various veneer materials to the surface of the substrate through hot melt adhesive. 

Working principle of Yongte PUR lamination machine for WPC door panel

The hot glue coating machine uses solid hot melt adhesive, which is placed in the hot glue box for heating and melting, and then the glue is evenly applied to the substrate or veneer material through the glue supply system. Then, various forming rollers are used to simulate the manual veneer action, and the veneer material is tightly attached to the surface of the substrate, and it is fixed by rolling the roller to form the envelope of the profile, and finally the coating work is completed.

Structural composition of Yongte PUR lamination machine for WPC door panel

- Frame: As the supporting structure of the entire equipment, it ensures the stability of the equipment and the installation accuracy of each component.

- Feeding system: Responsible for conveying the substrate to the coating work area at the set speed and direction, usually composed of motors, transmission devices, conveying wheels, etc., which can achieve uniform and stable feeding.

- Hot glue system: including hot glue box, heating element, temperature control system, glue supply device, etc. The hot glue box is used to contain and heat the hot melt glue, the heating element ensures that the glue reaches the appropriate working temperature, the temperature control system can accurately adjust and maintain the glue temperature, and the glue supply device evenly supplies the molten glue to the glue coating area.

- Gluing device: According to different machine models and process requirements, the glue coating device has various forms, such as glue rollers, scrapers, etc. Its function is to evenly apply hot glue on the substrate or veneer material and control the amount of glue and the uniformity of glue coating.

- Pressing system: It consists of multiple forming rollers. The shape and arrangement of the rollers are designed according to different profile contours and coating requirements. The rollers apply a certain pressure through air pressure, hydraulic pressure or mechanical devices to make the veneer material fit closely with the substrate, ensure the coating quality, and avoid problems such as bubbles, wrinkles or debonding.

- Control system: The electrical control system is used to set, adjust and monitor various parameters of the equipment, such as feeding speed, glue box temperature, glue coating amount, roller pressure, etc. It also has safety protection functions such as fault alarm and automatic shutdown to ensure the normal operation of the equipment and the safety of operators.

Features of Yongte PUR lamination machine for WPC door panel

- Good environmental performance: Hot melt adhesive does not volatilize solvents during use. Compared with the liquid adhesive used by cold glue coating machines, it can effectively reduce the emission of volatile organic compounds (VOCs), is more environmentally friendly, and meets environmental protection requirements.

- High bonding strength: Hot melt adhesive has good fluidity and viscosity after heating and melting, and can penetrate into the tiny pores of the substrate and veneer materials. After cooling and solidification, it forms a strong bond, so that the coated product has a higher bonding strength and is not prone to debonding, which improves the quality and service life of the product.

- High production efficiency: The hot glue coating machine has a high degree of automation and is equipped with an advanced feeding system, glue coating system and pressing system, which can achieve continuous and stable production, greatly improving production efficiency. At the same time, its fast curing characteristics also reduce the waiting time in the production process, further improving production efficiency.

- Wide range of applications: It can be used for coating a variety of substrates and veneer materials, such as wood lines, medium density fiberboard, wood plastic, plastic steel, PVC, aluminum profiles and other lines, as well as PVC decorative film, decorative paper, solid wood veneer, Boeing board, composite aluminum film and other veneer materials, which can meet the needs of different industries and customers.

- Good coating effect: Through precise temperature control, uniform glue coating and appropriate lamination process, the hot glue coating machine can make the veneer material fit closely with the substrate, with a smooth surface, without obvious bubbles, wrinkles or defects, to achieve a good coating effect and improve the appearance quality and decorative performance of the product.
