Double elements gas-fog products filling device and pour-in method thereof

Abstract

This invention provides a filling device and method of binary aerosol product including the reagent filling system and propellent filling system. The propellent filling system includes the propellent container, the compressed air source, vacuum system, the filling machine, the dosing device and the fixing machine of the aerosol can; the filling machine includes the frame and the filling head with the cavity inside on the frame. The gland machine is positioned in the middle of the cavity, the seal sleeve is positioned in the upper part of the cavity and the seal ring is at the bottom of the seal sleeve. The propellent container is connected to the input of the dosing device via pipelines and the output is connected to the cavity of the fill head. The vacuum device is connected to the cavity of the fill head via pipelines; the compressed air source is connected to the upper part of the shell and the cavity via pipelines. This invention can realize the quantitative filling of the reagent and propellent conveniently and safely and suits the industrialized production.

Description

technical field [0001] The invention relates to an aerosol product filling device and a filling method. Background technique [0002] Aerosol products are widely used in daily life, industrial production and anti-riot fields, such as daily chemical products, non-destructive testing, etc., all of which require aerosol products, especially a dual-element aerosol product. [0003] The so-called dual-element aerosol product refers to that the aerosol can is filled with two substances, one of which is a propellant and the other is an agent. [0004] For dual-element aerosol products, because all the agents are safely and reliably ejected from the aerosol can, it is a problem that needs to be paid close attention to in the production process of aerosol products. The key factor is how to quantitatively fill the propellant and the agent in the dual-element aerosol product according to the design requirements. [0005] Among them, the filling amount of the propellant is a key facto...

AI Technical Summary

Problems solved by technology

[0005] Among them, the filling amount of the propellant is a key factor, because the propellant is generally such as propane, butane or a mixture of propane and butane, which is liquid under pressure and gaseous under normal pressure, and is generally difficult to measure and fill. However, when the amount of propellant is too much, not only the production cost will increase unnecessarily, but also may cause safety hazards; when the amount of propellant is too small, all the objects cannot be ejected, wasting resources, and may cause environmental pollution

[0006] At present, the conventional method is to weigh the aerosol cans filled with propellants and agents for testing. If they do not meet the design requirements, they will be regarded as waste products, resulting in a low pass rate of products.

[0007] Chinese patent ZL99233174.9 discloses an aerosol production and filling device, in order to overcome the overly complicated defects of the previous devices, but does not solve the problem of how to quantitatively fill
