Multipurpose air curtain

Abstract

The invention discloses a multipurpose air curtain. The multipurpose air curtain comprises a transmission device, a curtain coating device located on the transmission device, a material barrel connected with the curtain coating device and a flow pump connected with the material barrel; the curtain coating device comprises a material box, an adjusting wrench, an adjusting plate, an eccentric wheeland a curtain coating head; the material box is provided with an outflow opening, and the adjusting wrench, the adjusting plate, the eccentric wheel and the curtain coating head are mounted on the material box and mutually matched. The multipurpose air curtain can evenly smear coatings on the surfaces of materials, has high production efficiency and long service life, and can be applied to the materials with various hardness and thicknesses.

Description

technical field [0001] The invention relates to a mechanical device for coating the surface of leather, wood, glass and other products, in particular to a curtain drenching machine for realizing the above purpose. Background technique [0002] The industry generally needs to finish the surface of leather, wood, glass and other products. For example, in the leather industry, a layer of paint is required on the surface of the leather in order to increase the performance of the leather and at the same time increase the aesthetics of the leather. [0003] One method is manual rubbing, that is, completely relying on manual coating of paint on the leather surface. This method is not only inefficient, but also the paint applied is extremely uneven. [0004] Another method is to use a spraying machine, but the spraying amount of the spraying gun of the spraying machine is small each time, and it needs multiple spraying operations to completely coat the paint, which seriously affec...

This method is not only inefficient, but also the coating is extremely uneven

[0004] Another method is to use a spraying machine, but the spraying amount of the spraying gun of the spraying machine is small each time, and it needs multiple spraying operations to completely coat the paint, which seriously affects the production efficiency, and the spraying gun sprays a large amount of mist paint. Among them, 20%-25% of the mist paint is sucked away by the ventilation and dust removal system in the air, which not only causes waste, but also causes environmental pollution.

[0005] Another commonly used method is to use a roller finishing machine for operation, but the roller finishing machine has very high requirements on the thickness and hardness of the leather material (hard materials such as glass and wood cannot be coated with the roller finishing machine)

If the thickness of the leather is uneven, it will cause the thinner parts to be rolled and the coating will not be applied

In addition, long-term contact and friction between the roller shaft and the surface of the leather material may easily cause wear and deformation of the roller shaft, thereby seriously affecting the uniformity of the painted surface
