A kind of special-shaped surface coating device for wood strips

Abstract

The invention discloses a wood molding painting device for different surfaces. The device includes a conveying roller way, and a first conveying group, a painting group for different surfaces and a second conveying group are arranged on the outer side of the conveying roller way in the transmission direction; the first conveying group and the second conveying group are identical in structure and include multiple pressing wheel groups and limiting wheel groups both of which are arranged side by side, wherein the pressing wheel groups and the limiting wheel groups are alternately arranged with each other, and each pressing wheel group includes a pressing bracket positioned above the conveying roller way; a lifting screw rod is connected to the middle of each pressing bracket through a circular hole, a locking nut positioned on the top of the corresponding pressing bracket is arranged on each lifting screw rod, a rotatable pressing wheel is arranged at the lower end of each lifting screwrod, the outer side of each pressing wheel is in an arc shape, a push motor is connected to one side of each pressing wheel through a chain of a chain wheel, the push motors are connected with the lifting screw rods through mounting racks, and pressure springs positioned on the outer sides of the lifting screw rods are arranged between the mounting racks and the pressing brackets. The device has the advantages of being high in coating efficiency, great in coating effect and high in applicability.

Description

technical field [0001] The invention relates to a wood strip painting device, in particular to a wood strip special-shaped surface painting device. Background technique [0002] At present, in order to have good aesthetics and structural strength, the wood moldings on the market often need to be made into a streamlined profiled surface; but because most of the conventional painting devices can only paint the plane, they cannot be applied to wood The special-shaped cross-section coating work of the lines has caused manufacturers to use manual coating or mechanical spraying to complete the coating of the special-shaped surfaces of the wood lines. However, the manual coating method will not only reduce the painting efficiency and increase the labor cost, but also cause uneven thickness of the paint surface during the painting process, thereby reducing the painting effect of the wood strips; and mechanical spraying Although the method can improve the coating efficiency and the ...

Problems solved by technology

[0002] At present, in order to have good aesthetics and structural strength, the wood moldings on the market often need to be made into a streamlined profiled surface; but because most of the conventional painting devices can only paint the plane, they cannot be applied to wood The special-shaped cross-section coating work of the wood lines requires the manufacturer to complete the coating by manual coating or mechanical spraying when coating the special-shaped surface of the wood lines.

However, the manual coating method will not only reduce the painting efficiency and increase the labor cost, but also cause uneven thickness of the paint surface during the painting process, thereby reducing the painting effect of the wood strips; and mechanical spraying Although the method can improve the coating efficiency of the wood strips and the uniformity of the paint film, it needs to consume a large amount of paint during the spraying process, thereby increasing the painting cost of the wood strips

In addition, due to the different surface heights and concave depths of different wood strips, the conventional mechanical spraying device will also have the problem of limited spraying height and inability to spray completely, and the paint film after spraying will also be affected by the special-shaped surface. The higher height of the different surface paint film is thicker, and the lower height of the different surface paint film is thinner, which is not completely suitable for the different surface coating of wood strips with different height differences.

Therefore, the existing brushing method for the special-shaped surface of the wood strips has the problems of low brushing efficiency, poor brushing effect and low applicability
