Description

Technical Field

[0001] The utility model relates to the technical field of easy-to-clean nozzles, in particular to an easy-to-clean nozzle for a spraying production line. Background Art

[0002] In the process of spraying on the spraying production line, a spray gun is needed to atomize the paint and apply it to the surface of the object. The nozzle is designed to work under a variety of different spray conditions. Therefore, a nozzle suitable for the needs is selected to achieve the best spray performance during use. At the same time, it also needs to be easy to clean.

[0003] According to the description of an easy-to-clean nozzle for a spray production line disclosed on the patent website (authorization announcement number: CN216440942U), "The utility model discloses an easy-to-clean nozzle for a spray production line, including a nozzle tube, one end of the nozzle tube is fixedly connected to a nozzle valve by bolts, and the outer wall of the nozzle valve on the side away from the nozzle tube is fixedly connected to a nozzle connection seat by bolts, and a through spray hole is opened inside the nozzle tube, and a limiting ring is embedded on the inner wall of one side of the spray hole, and a threaded groove is opened on the inner wall of one side of the spray hole at a position close to the limiting ring. The easy-to-clean nozzle for the spray production line can remove and clean the first curved plate and the second curved plate when cleaning the nozzle tube through the mutual cooperation of the first curved plate, the second curved plate and the spray hole, which not only avoids the problem of incomplete cleaning of the nozzle tube due to insufficient cleaning of the inner wall of the tubular structure, but also realizes the replacement of the first curved plate and the second curved plate inside the nozzle tube, and avoids the use of the nozzle due to too long cleaning and drying time."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model takes out the arc plate for cleaning to avoid incomplete cleaning, and uses the through hole to clean the inside of the nozzle tube to remove residual liquid inside. However, in actual use, when the nozzle is used for spraying, the paint will be sprayed directly from the nozzle tube. When there are impurities in the paint, the nozzle that cannot filter and screen will cause the impurities to affect the spraying quality. Therefore, it is necessary to improve an easy-to-clean nozzle for a spray production line to solve the above problems. Utility Model Content
