Wood door spray painting machine belongs to large-scale automatic spray painting equipment. It is a special coating equipment for wood door industry. In the wood door coating production, the wood door paint spraying machine is the main working equipment. Due to its low efficiency compared with the roll coating production line, it can reach the expected output almost by running at full load every day. Wood door spray painting machine is a precision equipment, especially the quality of spray gun largely determines the spraying effect, so the cleaning of spray gun of wood door spray painting machine is very important.
The cleaning of the spray gun is the cleaning of the whole spray gun mechanism. Not only the nozzle should be cleaned carefully, but also the pump should be used for cleaning.
First, clean the whole pipeline, loosen the nozzle by 2 buckles, release the pressure, and start the spray gun to let the excess liquid paint in the pipeline flow out. Then pour out the residual paint flowing out and inject a cleaning solvent with good solubility. Usually, banana water or other thinner is used to continuously inject the solvent and blow it out from the spray gun head, reciprocating so that the deposited or solidified paint in the pipeline can be completely discharged.
Finally, for the spray gun itself, remember not to remove the spray gun and immerse it in the cleaning solvent as a whole. Some internal sealing gaskets are not resistant to diluent, which is easy to cause swelling or air leakage. The correct step should be to remove the air cap, soak only the spray gun head, brush it with a soft brush dipped in solvent, and finally dry it with a clean cotton cloth. If you are more careful, you can install the spray gun and start the equipment to simulate the spraying operation with only air, so as to ensure that the interior of the spray gun and the interior of the pipeline can be quickly dried and put into normal use after cleaning.
Regular cleaning of the whole wooden door painting machine can reduce the content and density of volatile paint in the painting room to a certain extent. Careful and correct cleaning of the spray gun is a necessary work to prolong the service life of the equipment and ensure the spraying quality.
