Description

Bottle cap gasket plugging machine

Technical Field

The invention belongs to the technical field of bottle cap production, and particularly relates to a bottle cap gasket plugging machine.

Background

The bottle cap gasket can enhance the air tightness, ensure the close fit between the bottle cap and the bottle mouth, and the bottle cap gasket plugging machine is equipment for plugging the gasket into the bottle cap and generally comprises an automatic feeding mechanism, a material taking dividing plate, a plug flushing mechanism, an automatic discharging mechanism and the like.

The most important of bottle cap gasket plugging machine is to plug gaskets into a bottle cap, the common gasket plugging mechanism firstly adsorbs the gaskets in a negative pressure adsorption mode, then plugs the gaskets into the inner bottom of the bottle cap under the action of external driving pressure (such as a bottle cap gasket plugging machine disclosed in patent publication No. CN 114751001A), and the connection mode between the gaskets and the bottle cap is generally divided into two modes, namely an adhesive fixing mode, the gaskets are easy to pollute medium in the bottle body due to glue overflow phenomenon, and the working procedure is increased, so that the application is less, and the other is that barbs are reserved on the inner wall of the bottle cap during injection molding production, the gaskets can be prevented from falling out through blocking limit of the barbs, and the mode is easy to produce and wide in application.

However, in the barb connected mode, because the diameter of gasket needs to be greater than the internal diameter of barb, in the plug head with the gasket stopper in-process, the outer fringe of gasket is easy to closely laminate with the barb, will lead to the difficult timely discharge of gasket below air like this, thereby it possibly has the air bulge phenomenon to lead to between gasket and the inner bottom of bottle lid after the gasket is plugged in, in case the air that remains is too much, just there is because of atmospheric pressure effect, the possibility that the gasket drops appears, simultaneously because the gasket thickness is less, the distance between barb and the inner bottom of the bottle lid is also less, because of the processing error influence, there is the gasket outer fringe card in the barb outside, the phenomenon of not completely income end, lead to the gasket to drop more easily.
