Embodiment 1
[0046] Such as Figure 1 to Figure 3 As shown, the fluid pipeline paint supply system for automatic color-changing metering spraying of the present invention mainly consists of three fluid sections, which are respectively a paint supply section, a cleaning section, and a color-changing valve return section.
[0047] The paint supply section includes multiple paint supply systems 1, fluid plate assembly 2, metering cylinder module 3, spraying robot module 4, feed pipe, and return pipe, and the fluid plate assembly 2 includes color change valve 21, color change valve manifold Pipe 22, fluid valve group manifold 23, metering cylinder module 3 includes metering cylinder body 31, multiple plunger pumps 32, metering cylinder body 31 simultaneously drives multiple plunger pumps 32 to complete feeding and discharging actions, spraying robot module 4 Including a plurality of spray guns 41 and a spray gun manifold 42, a plurality of paint supply systems 1 are respectively connected to a...
Embodiment 2
[0056] Such as Figure 1 to Figure 3 As shown, based on the fluid pipeline paint supply system of Embodiment 1, a fluid pipeline paint supply method for automatic color-changing metering spraying of the present invention:
[0057] Including step S1. Automatic color-changing paint supply method:
[0058] S11. Multiple paint supply systems deliver paints of different colors to multiple paint channels of the color change valve, and the paint channel of each color change valve corresponds to a paint supply system of a color;
[0059] S12. Paint supply step: the color change valve 21 and the fluid valve group manifold 22 both open a paint channel for a color paint, the paint forms a closed-loop flow in the feed pipe and the return pipe, and the metering cylinder body 31 drives the plunger pump 32 execute the pumping action, close the paint channel of the color change valve 21 and the fluid valve group manifold 22 after the pumping is completed; before the spray gun is sprayed, the...

Abstract
The invention relates to a fluid pipeline paint supply system capable of automatically changing color, metering and spraying and a corresponding paint supply method. The fluid pipeline paint supply system comprises multiple paint supply systems, a fluid disc assembly, a metering cylinder module, a spraying robot module, a feed pipe, and a return pipe; the fluid disc assembly comprises a color change valve, a color change valve manifold, and a fluid valve set manifold; the metering cylinder module comprises a metering cylinder body and multiple plunger pumps; the metering cylinder body synchronously drives the multiple plunger pumps to complete feed and discharge actions; the spraying robot module comprises multiple spray guns and a spray gun manifold; and multiple paint supply systems, thecolor change valve, the color change valve manifold, multiple plunger pumps, multiple spray guns, the spray gun manifold and multiple paint supply systems are sequentially connected by means of the feed pipe and the return pipe. The whole flow channel and related valve sets are redesigned and arranged to form closed-loop spraying, so that the paint cost is lowered, the spraying quality is improved, and the defect of spraying breakage caused by air generated in a pipeline due to higher speed during plunging is overcome.
Description
technical field [0001] The invention relates to the field of automatic spraying, in particular to a fluid pipeline paint supply system and method for automatic color-changing metering spraying. Background technique [0002] Coating is an important link in the modern product manufacturing process. Anti-rust, anti-corrosion coating quality is one of the important aspects of product overall quality. Product appearance quality not only reflects product protection and decoration performance, but also an important factor that constitutes product value. [0003] Coating is a systematic project, which includes three basic processes: treatment of the surface of the object to be coated before coating, coating process and drying, as well as designing a reasonable coating system, selecting suitable coatings, determining good working environment conditions, and carrying out Important links such as quality, process management and technical economy. [0004] Therefore, painting has high...
