Anti-drawing filling nozzle

Abstract

The invention discloses an anti-drawing filling nozzle. The anti-drawing filling nozzle comprises a filling nozzle body. A sealing guide column is arranged on the top end of the filling nozzle body. One end of the sealing guide column is fixedly connected with a driving shearing rod. The upper end of the sealing guide column is fixedly connected to an output end of a cylinder. A three-way valve body is arranged inside of the filling nozzle body. One end of the three-way valve body is connected with a feeding port. A discharge pipe is connected to the lower end of the filling nozzle body by means of a docking screw sleeve. One end of the three-way valve body inside the filling nozzle body is communicated with the discharge pipe; and one side of the driving shear rod away from the sealing guide column passes through the three-way valve body, and is arranged inside the discharge pipe. A shearing knife is fixedly connected to one end of the driving shearing rod inside the discharging pipe.The bottom end of the discharging pipe is provided with a discharge port. An inner side wall of the feeding port is provided with an internal thread. An infusion tube is fixedly connected to a feeding port by means of a connector. An outer surface at one side of the connector is provided with an external thread.

Description

technical field [0001] The invention relates to the field of filling nozzle design, in particular to an anti-drawing filling nozzle. Background technique [0002] It is mainly used in cosmetics, medicines, food, and industrial glue. During the production process, materials with high viscosity will have stringing phenomenon in the filling process, and the materials will remain at the packaging interface of the packaging materials. Affect the sealing effect at the interface, which may cause the material to flow out of the package, which will affect the product quality to varying degrees. At the same time, it will produce waste of production material and increase production costs. In the filling process of bottled containers, it is often necessary to quantify the fluid Filling, that is, injecting the required fluid from a large container into a designated container through quantitative filling equipment. The filling gun equipment of the prior art is exactly a kind of quantitat...

Problems solved by technology

[0003] However, the filling nozzles currently on the market only have the function of plugging, and when the material liquid with a large consistency is discharged, it is easy to have the phenomenon of material body drawing and accompanied by air bubbles, and there are certain disadvantages in use.
