Anti-hanging wire filling nozzle

Abstract

The invention discloses a material-suspension-preventing filling nozzle, comprising a valve body, a sealing element and a valve rod, wherein a valve chamber is arranged inside the valve body; a discharge hole communicated with the valve chamber is formed in one end of the valve body; the valve rod is sleeved with the sealing element; the valve rod is arranged inside the valve body; a concave hole is formed in the bottom of the valve rod; air inside the concave hole is taken away when a material flows out downwards from the discharge hole, so that a negative pressure air chamber is formed inside the concave hole; the material remained between the discharge hole and the opening of a container is gradually thinned under the action of gravity after filling is stopped; tailing is adsorbed upwards due to existence of negative pressure inside the concave hole when a little of tailing is left. Meanwhile, molecular action force exists between the tailing inside the gap of the discharge hole and the tailing suspended outside the material opening, and the tailing suspended at the material opening is adsorbed onto the edge of the gap of the discharge hole under the action of two forces, so as to prevent the phenomenon of tailing suspension, and prevent the concave hole from being plugged. No tailing is suspended outside the discharge hole, so that pollution caused by the tailing dripping on ground equipment also can be completely eradicated.

Description

technical field [0001] The invention relates to the technical field of filling equipment, in particular to an anti-hanging wire filling nozzle. Background technique [0002] When filling the liquid into the container, a filling nozzle is needed. The liquid is poured into the container from the filling nozzle. The high-viscosity liquid has high viscosity, poor fluidity, low surface tension and strong adhesion. , High-viscosity liquids are easy to form hanging threads on the filling nozzle. Due to the existence of hanging threads, on the one hand, it causes waste of materials, and on the other hand, it pollutes the container mouth and filling nozzle, thus affecting the filling production. Contents of the invention [0003] The object of the present invention is to provide an anti-snag filling nozzle capable of preventing liquid from being spun and remaining. [0004] In order to realize the purpose of the present invention, the technical scheme that takes is: [0005] An a...

[0002] When filling the liquid into the container, a filling nozzle is needed. The liquid is poured into the container from the filling nozzle. The high-viscosity liquid has high viscosity, poor fluidity, small surface tension and strong adhesion. , High-viscosity liquids are easy to form hanging threads on the filling nozzle. Due to the existence of hanging threads, on the one hand, it causes waste of materials, and on the other hand, it pollutes the container mouth and filling nozzle, thus affecting the filling production.
