Problems solved by technology

In the woodworking industry, it is necessary to use double-speed chains to conduct automatic painting work, while the traditional plane reciprocating painting production line can only solve the problem of painting flat thin boards, and the painting effect of thick boards and boards with grooves and round edges is not good.
[0003] In terms of the choice of spray paint, the traditional spray paint production line can only spray oil-based paint, while solvent-free UV paint, water-based paint and water-based UV paint cannot be sprayed.
Traditional oil-based paint is not only expensive, but also easy to cause waste

Abstract

The invention relates to the field of automatic paint spraying production lines, in particular to an automatic paint spraying production line and a paint spraying process thereof. The automatic paintspraying production line comprises a speed chain assembly line body, and further comprises a feeding line mechanism, a dust removing mechanism, a color correcting mechanism, a paint spraying mechanism, a cooling mechanism and a discharging line mechanism which are sequentially connected through the speed chain assembly line body. According to the automatic paint spraying production line, a speed chain is used as a transportation carrier, the feeding line mechanism, the dust removing mechanism, the color correcting mechanism, the paint spraying mechanism, the cooling mechanism and the discharging line mechanism are integrated for use, so that the automatic paint spraying production line solves the paint spraying problem of plane thin plates, and thick plates and plates with grooves and round edges can be automatically sprayed with the good effects; and spraying of an oily paint, a solvent-free UV paint, a water-based paint and a water-based UV paint can be realized at the same time, different paint types can be selected for spraying according to requirements and cost so that the use amount of the paint can be saved, and a lot of labor cost can be saved.

Description

technical field [0001] The invention relates to the field of automatic conveying production lines, in particular to an automatic painting production line and a painting process thereof. Background technique [0002] At present, in the automatic material conveying assembly line, the use of double-speed chain as the transportation method is more efficient and commonly used in the automatic material conveying assembly line, and the tooling board is the carrier for the material. In the woodworking industry, it is necessary to use double-speed chains to conduct automatic painting work, while the traditional planar reciprocating painting production line can only solve the problem of painting flat thin plates, and the painting effect of thick plates and plates with grooves and round edges is not good. [0003] In terms of the choice of spray paint, the traditional spray paint production line can only spray oil-based paint, but solvent-free UV paint, water-based paint and water-base...
