UV Flat Wood Spraying Line Introduction
The UV flat wood spraying line is an automated production line specifically designed for the spraying of UV paint on the surface of wooden products, which is widely used in industries such as furniture manufacturing. The following is a detailed introduction to it:
Loading Area: Usually equipped with a loading platform and conveying device. Workers place the wooden boards to be sprayed on the loading platform, and the conveying device will accurately send the boards into the next process of the spraying line at a set rhythm and direction.
Dust Removal Area: Generally equipped with dust removal equipment such as electrostatic dust guns and brush roller dust removal devices. Dust, wood chips and other impurities on the surface of the wood are removed through electrostatic adsorption or physical brushing, ensuring the cleanliness of the spraying surface and improving the adhesion of the paint and the spraying quality.
Primer Spraying Area: It includes a spray gun system, paint supply system and paint mist treatment system. The spray gun system mostly uses high - pressure airless spray guns or electrostatic spray guns, which can evenly spray the UV primer on the surface of the wood. The paint supply system is responsible for accurately supplying the paint to ensure the continuity of spraying. The paint mist treatment system treats the paint mist generated during spraying through methods such as water curtains and activated carbon adsorption, protecting the environment and equipment.
Leveling Area: Usually, it is a conveying channel with a certain length. The wooden products sprayed with primer move at a constant speed in this area. Under the action of gravity and surface tension, the primer levels naturally to form a uniform coating, reducing defects such as sagging and orange peel.
UV Curing Area: Mainly composed of UV lamp curing equipment, common ones include mercury lamps, LED - UV lamps, etc. When the wood enters the curing area, the UV lamp emits high - intensity ultraviolet light. The photoinitiator in the UV paint absorbs light energy and generates free radicals, triggering the polymerization reaction of resins and monomers, so that the paint can be quickly cured in a short time.
Grinding Area: Generally equipped with grinding equipment such as belt sanders and disc sanders. The surface of the cured primer is polished to eliminate surface unevenness, improve surface flatness, and provide a good foundation for the subsequent top - coat spraying.
Top - coat Spraying Area: Similar to the primer spraying area, it is composed of systems such as spray guns, paint supply and paint mist treatment. It is mainly used to evenly spray the UV top - coat on the surface of the wood that has been treated with primer and polished, improving the gloss, hardness, wear resistance and other properties of the wood.
Secondary Curing Area: The wooden products sprayed with top - coat are cured again through UV lamp curing equipment to ensure that the top - coat is completely cured, forming a firm and stable coating.
Unloading Area: Equipped with an unloading platform and conveying device, the wooden products that have completed spraying and curing are removed from the spraying line for subsequent operations such as packaging and warehousing.
First, the wooden boards are sent onto the conveyor line in the loading area. After dust removal, they enter the primer spraying area, where the spray gun sprays the UV primer on the surface of the wood. Subsequently, it levels in the leveling area. Then, it enters the UV curing area, and the primer is rapidly cured under the action of ultraviolet light. After the cured wood is polished in the grinding area to remove surface defects, it enters the top - coat spraying area to spray the top - coat. Finally, the top - coat is cured in the secondary curing area, completing the entire spraying process.
Fast Curing Speed: UV paint can be quickly cured in a few seconds to tens of seconds under ultraviolet light irradiation, greatly improving production efficiency and shortening the production cycle.
Good Environmental Performance: Almost no volatile organic compounds (VOCs) are generated during the curing process of UV paint, which meets environmental requirements, reduces environmental pollution and harm to human health.
Excellent Coating Performance: The cured UV coating has characteristics such as high hardness, high gloss, good wear resistance, chemical resistance and water resistance. It can effectively protect the surface of the wood and extend the service life of the wood.
High Degree of Automation: The entire spraying process can be automated, reducing manual intervention, improving the stability and consistency of spraying quality, and also reducing labor costs.
Space - Saving: Due to the fast curing speed, the overall length of the UV flat wood spraying line is relatively short, which can effectively save the space of the production workshop.
Furniture Manufacturing: Widely used in the surface spraying of various solid wood furniture and panel furniture, such as wardrobes, cabinets, tables and chairs, etc., providing beautiful and durable coatings for furniture.
Wooden Door Production: Used for the surface spraying of wooden doors, which can make the wooden doors have good decorative effects and protective properties, improving the quality and grade of the wooden doors.
Wood Floor Processing: In the production process of wood floors, the UV flat wood spraying line can spray the surface of the wood floors, making them have properties such as wear resistance, scratch resistance and moisture resistance, and at the same time enhancing the appearance texture of the wood floors.
Manufacture of Wooden Crafts: For various wooden crafts, such as wood carvings and wooden ornaments, the UV flat wood spraying line can provide them with beautiful surface coatings, enhancing the artistic effect and preservation value of the crafts.
