Description

[0002] Spray nozzles can be seen everywhere in daily life. The sealing ring on the spray nozzle pump core is one of the essential parts of liquid and gas spray containers. The effective installation of the sealing ring can not only prevent the leakage and volatilization of the substances inside the container, ensure product quality and improve service life, but also ensure the stability of the aerosol spray during spraying. According to the production needs of a certain company, the characteristics of the spray nozzle pump core and the sealing ring structure and manual assembly were studied. It was found that in order to ensure the sealing, the inner diameter of the sealing ring is slightly smaller than the outer diameter of the spray nozzle pump core, which leads to time-consuming and labor-intensive manual assembly, low efficiency, and the consistency of products due to different operating experience is difficult to guarantee. Further analysis of the factors leading to defective products found that the main reasons were that the height position of the sealing ring assembly was not up to standard and the sealing ring was twisted on the spray nozzle pump core. In addition, during the peak season when the order volume is large and the delivery cycle is short, the contradiction of manual assembly is particularly prominent.

[0003] In order to replace the traditional manual assembly production mode, the automatic production management level of the seal ring of the nozzle pump core is proposed, a six-segment cam ring mechanism is proposed, and a rotary assembly barrel step-by-step mechanism is designed to assemble the two together step by step.
