Description

Spray equipment

Technical field

The utility model refers to a kind of spray equipment of application of air spraying especially relevant for a kind of spray equipment.

Background technology

Japanning is the key step of coating application.For obtaining desirable filming, the conditions such as japanning efficient that must reach according to character, Workpiece structure and the requirement of coating are accurately selected method of lacquering.Except that traditional brushing method, now current method has aerial spraying, electrodeposition coating, deposit application, dip-coating, roller coating and curtain automatically is coated with etc.

See also Fig. 1, existing aerial spraying device is located in the spray room 1a of production line usually, include: a gear unit 2a, a spray unit 3a, a washing unit 4a and mend wind unit 5a, this gear unit 2a has a chain 21a and a plurality of carrier 22a, this chain 21a utilizes the motor transmission, pass through through this spray room 1a, these a plurality of carrier 22a are located on the chain 21a, and carrier 22a can be in order to place object to be sprayed.Spray unit 3a has one or many spray gun 31a, and these many spray gun 31a are fixedly arranged on the side of chain 21a, and the nozzle of spray gun 31a faces object to be sprayed.This washing unit 4a is located at the side of spray room 1a, the water that washing unit 4a from top to bottom flows out is a water curtain shape, in order to allow the coating cloud behind air atomizing be adhered to, discharges spray room 1a rapidly, avoid its spray room 1a in disturbance drop in the spraying after product surface, cause defective products.Mend wind unit 5a be located at spray room 1a directly over, can continuously send fresh air, and will spray air in the room 1a and blow to washing unit 4a washing and discharge, again via the opening 11a discharge of spray room 1a one side.

When above-mentioned aerial spraying device in use, because the air flow that benefit wind unit 5a blows out is different with the lacquer liquid direction of spray gun 31a ejection, make a large amount of coating clouds behind air atomizing be easy to generate flow-disturbing, the easy on the one hand product surface that therefore descends slowly and lightly after spraying causes defective products to increase; A large amount of lacquer liquid there is no and is sprayed at exactly on the object to be sprayed on the one hand, but is sprayed in the air, and the paint vehicle utilization rate is low, causes very big waste.

Therefore, the utility model creator improves thoughts on above-mentioned disappearance, and the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance finally.
