Background

In life, many articles are pasty, such as: toothpaste, eyeliner, ointment, etc.

During the production process of a factory, a pipeline is often used for conveying pasty articles, and the tail end of the pipeline is vertical. When the pasty article is injected into the container, the opening of the container is sleeved to the opening of the pipeline, the pasty article in the pipeline is extruded from the pipe orifice and is injected into the container, after a preset amount of pasty article is filled in the container, the extrusion of the pasty article in the pipeline is stopped, and then the container is taken down.

Meanwhile, the packaging of the paste-like article can be divided into two types: soft and hard packaging. When the soft package of the paste-like article (such as toothpaste) is taken, the paste-like article (toothpaste) is squeezed out from the tube opening by pinching the outer package (toothpaste tube) by hand.

During the extrusion process of the paste-like object, the paste-like object may be attached to the nozzle, and further dirt such as dust is easily adhered to the nozzle.

In one embodiment, the outer circumference of the shut-off member 4 is sealed from the inner circumference of the paste outlet 22 and the inner circumference of the shut-off member 4 is adapted to fit to and seal against the outer circumference of the spindle 31. When the paste is extruded, the paste pushes the cut piece 4 and enables the cut piece 4 to generate elastic deformation, so that a gap is formed between the inner periphery of the cut piece 4 and the outer periphery of the mandrel 31, and the paste is output from the gap; when the squeezing out of the paste is completed, the cutting part 4 is restored to the original state and is matched with the mandrel 31, so that the paste is cut off, and the paste outlet 22 is kept clean and sanitary.

Specifically, referring to fig. 2 and 4, cutting member 4 includes a connecting sleeve 41, a cutting ring 42, and an abutment ring 43. The connecting sleeve 41 is coaxially embedded into the caulking groove 21, one end of the connecting sleeve 41 is attached to the bottom of the caulking groove 21, and the other end of the connecting sleeve 41 slightly extends out of the paste outlet 22. And the inner diameter of the connecting sleeve 41 is equal to the inner diameter of the connecting pipe 2, and the outer periphery of the connecting sleeve 41 and the side wall of the caulking groove 21 can be sealed through interference fit.
