Automatic backflow detection equipment for foam pump piston

Abstract

The invention relates to foam pump piston automatic backflow detection equipment. The equipment comprises a rack, wherein a machine table is arranged on the rack, and at least one lower sealing jig, at least one upper sealing jig, an upper sealing jig air pressure detection device, a lower sealing jig air pressure detection device and an air pressure pumping-in device are arranged on the machine table. A lower end of a foam pump piston is supported and sealed through a lower sealing jig, an upper sealing jig is pressed downwards to cover and seal an upper end of the foam pump piston, air flowflows to a lower end of the interior from a hole in an upper end of the foam pump piston by pumping air pressure, the air pressure conditions of the upper end and the lower end are detected, and the pressure difference is calculated, so whether the foam pump piston leaks or not is identified, full-automatic detection is achieved, misjudgment caused by manual detection is eradicated, and detectionefficiency and detection precision are high.

Description

【Technical field】 [0001] The invention relates to the technical field of foam pump automatic processing equipment, in particular to a foam pump piston automatic backflow detection device. 【Background technique】 [0002] Nowadays, people are paying more and more attention to their own health and hygiene issues. In order to keep the human body clean, people are now accustomed to using some cleaning liquids when washing their hands, face or bathing. There are a lot of cleaning liquids such as face wash, hand sanitizer, shower gel, etc., and for the convenience of placement and use, the foam pump came into being. When in use, the foamy fluid can be output by pressing the head, which is energy-saving, environmentally friendly, and convenient for people to use. [0003] But at present, after the foam pump is pressed to produce foam, a part of the foam will remain in the liquid outlet channel. When it is not used for a period of time, the foam in the channel will be liquefied into ...

Problems solved by technology

[0003] But at present, after the foam pump presses out the foam, a part of the foam will remain in the liquid outlet channel. When it is not used for a period of time, the foam in the channel will liquefy into the original liquid

If the anti-seepage structure of the foam pump is poor, the liquefied raw liquid will leak back into the cylinder, affecting the work of the cylinder, resulting in poor rebound of the foam pump, affecting the feeding of air, thus affecting the normal use and function of the foam pump. Therefore, before the production leaves the factory, it is necessary to detect the automatic return of the foam pump, that is, to check the anti-leakage of the foam pump to prevent the outflow of defective products
