Painting machine off-line cleaning device

Abstract

The invention provides a painting machine off-line cleaning device. The painting machine off-line cleaning device mainly comprises a machine body, a solvent box, a solvent pipeline, a compressed air pipeline, a cleaning header pipe and a testing pipeline, wherein the solvent box, the solvent pipeline, the compressed air pipeline, the cleaning header pipe and the testing pipeline are arranged in the machine body; the solvent box communicates with the cleaning header pipe through the solvent pipeline; the solvent pipeline is provided with a conveying pump; the compressed air pipeline communicates with the cleaning header pipe and is used for supplying compressed air into the cleaning header pipe; the cleaning header pipe is provided with a first cleaning branch pipe and a second cleaning branch pipe; the machine body is provided with a mixing pipe connector communicating with the first cleaning branch pipe, and a painting machine connector communicating with the second cleaning branch pipe; and the testing pipeline communicates with the painting machine connector and is used for testing the rotation speed of a painting machine. Based on the structure, the off-line cleaning device canthoroughly clean a mixing pipe and the paining machine, the bumper paining quality is ensured, meanwhile, the service life of the mixing pipe and the service life of the painting machine are prolonged, the consumable using quantity is decreased, and the maintenance and upkeep cost of the painting machine is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an off-line cleaning device for a coating machine. Background technique [0002] The spraying process of the automobile bumper is completed by the coating system mixing the varnish paint and the curing agent through the mixing tube and then using electrostatic spraying. If the colored varnish in the mixing tube is not cleaned for a long time after mixing, it is easy to form the phenomenon of paint hanging on the wall. That is, the so-called varnish is produced. Under normal circumstances, after two weeks of use, the coating machine and the mixing tube will produce paint stains. These paint stains are difficult to clean every time the color is changed, resulting in black spots on the first few bumpers after the color change. Poor quality affects the quality of painting and leads to bumper rework. [0003] In view of the above problems, at present, the only solut...

Problems solved by technology

Under normal circumstances, after two weeks of use, the coating machine and the mixing tube will produce paint stains. These paint stains are difficult to clean every time the color is changed, resulting in black spots on the first few bumpers after the color change. Poor quality, which affects the quality of painting, which leads to bumper rework

[0003] In view of the above problems, at present, the only solution is to shorten the maintenance cycle of the coating machine and directly replace the mixing tube and other related components. High disadvantage
