Description

Technical Field

[0001] The invention relates to a bottle cap manufacturing machine, in particular to a bottle cap silicone valve assembly machine. Background Art

[0002] When a bottle containing liquid is placed on its side, inverted or shaken, the liquid is easy to leak. In order to prevent the leakage of liquid, in the prior art, a silicone valve is installed in the bottle cap, and then a valve seat is installed to fix the silicone valve. A cut is opened in the center of the silicone valve. When there is no external force to deform the silicone valve, the cut is tightly closed. When the bottle is placed on its side, inverted or shaken, the liquid inside will not leak. Only when the bottle body is stressed, the liquid inside will exert pressure on the silicone valve, and the cut will be deformed and opened after being pressed to pour out the liquid.

[0003] However, the silicone valve and the valve seat are two components of the bottle cap, and these two components are assembled with the bottle cap one by one later. Since the silicone valve is assembled by placing the silicone valve and the valve seat together and then assembling them into the bottle cap, it cannot be assembled in sections. In addition, due to the material properties of the silicone valve, it is easy to get stuck, break or be damaged during transportation. If the silicone valve and the valve seat are not fixed after assembly and then enter the next assembly process, it is easy to fall off, resulting in missing of the silicone valve. Since the silicone valve is inside the valve seat, it is difficult to detect whether the finished product is missing, which poses a huge quality risk.

[0004] At the same time, due to the material properties of silicone valves, a large amount of talcum powder is added before assembly to lubricate the silicone valve for easy transportation, which can easily cause workshop environmental pollution, damage assembly machine components, and may affect the quality of the liquid in the bottle.
