a paint system

Abstract

The invention relates to a paint spraying system, and belongs to the technical field of paint spraying. The paint spraying system comprises an air supply device and a paint supply device. The air supply device comprises an air supply header pipe. The air supply header pipe is connected with air supply branched pipes. The air supply branched pipes are connected with air inlets of spray guns. The paint supply device comprises paint spraying pumps, and the paint spraying pumps are connected with paint mixing barrels through paint feeding pipes. The paint spraying pumps are connected with the spray guns through paint discharging pipes. Paint outlets of the spray guns are connected with nozzles. The same paint discharging pipe is connected with at least two spray guns. The adjacent spray guns are connected through spray gun connecting pipes. A paint inlet of one of the spray guns is connected with the corresponding paint discharging pipe, and a paint discharging opening of the other spray gun is connected with a recycling bin through a paint return pipe. By the adoption of the multi-nozzle structure, pipeline arrangement can be simplified, cleaning difficulty of pipelines is lowered, and the pipelines can be recycled.

Description

technical field [0001] The invention relates to a paint spraying system, which belongs to the technical field of paint spraying, in particular to a multi-nozzle paint spraying system. Background technique [0002] Generally speaking, painting refers to a surface processing method in which paint is atomized by high-pressure airflow and sprayed onto the surface of the workpiece to form a special coating on the surface of the workpiece. The functions of spray paint are as follows: one is protective, which can prolong the life of the workpiece; the other is decorative, which can achieve beautiful and pleasant appearance; [0003] Existing painting installations such as figure 1 As shown, it includes air supply main pipe 1, triple valve 2, air supply branch pipe 3, paint spray pump 4, paint mixing bucket 5, paint outlet pipe 6, solenoid valve 7, paint spray booth 8, spray gun 9, nozzle 11 and paint mist 10 , the main problems in its use include: 1. The spray gun and the nozzle ...

Problems solved by technology

[0003] Existing painting installations such as figure 1 As shown, it includes air supply main pipe 1, triple valve 2, air supply branch pipe 3, paint spray pump 4, paint mixing bucket 5, paint outlet pipe 6, solenoid valve 7, paint spray booth 8, spray gun 9, nozzle 11 and paint mist 10 , the main problems in its use include: 1. The spray gun and the nozzle are all arranged in the spray booth, which will easily cause the spray gun to be polluted by paint mist, and then cause the cleaning of the spray gun to be difficult. The reason is that most of the existing spray gun cleaning methods use spray paint. The pump drives the cleaning solvent to pass through the paint spray pump, pipeline, spray gun and nozzle successively, which can clean the inside of the spray gun, but the outside of the spray gun polluted by paint mist cannot be cleaned well. First, the operation is troublesome, the usage of the cleaning solvent is increased and it is difficult to realize the recovery of the cleaning solvent, and the second is that the cleaning solvent is easy to enter the air duct of the spray gun, causing damage to the spray gun; Pour the cleaning solvent directly into the paint mixing bucket, or insert the paint inlet pipe into the cleaning solvent bucket, and use the paint spray pump to clean the paint mixing bucket, pipeline, paint spray pump, spray gun and nozzle together, but the cleaning of the paint mixing bucket is not thorough , it is easy to leave residues at the bottom of the paint mixing bucket, and it is difficult to recycle the cleaning solvent after the spray gun and nozzle cleaning are completed; 3. Existing paint mixing buckets such as figure 2 Shown, comprise paint mixing bucket 12, bung 13, pneumatic agitator 14, paint spray pump connecting pipe 15 and filter screen 16, often occur the problem that the paint at the bottom of paint mixing bucket cannot be used up during work, cause the waste of paint, increased Production cost; 4. Most of the existing paint spray pumps adopt a single nozzle structure, that is, each paint outlet pipe is only connected to one spray gun and nozzle, which makes the paint inlet pipeline complicated. First, it increases the difficulty of pipeline layout of the entire paint spraying device , the second is to increase the difficulty of cleaning the pipeline, which is prone to the problem of incomplete pipeline cleaning, and there is no paint return pipeline in the existing paint spraying device
