Description

Technical Field

[0001] This utility model relates to the field of filling valve technology, and in particular to a universal gas-filling valve for both cans and bottles. Background Technology

[0002] As people's living standards improve, their pursuit of beverages, beer, mineral water, and so on has become increasingly diversified and differentiated, moving beyond single products. The currently popular craft beer and various customized beverage products worldwide are a prime example. Manufacturers crave filling equipment that can adapt to different bottle types and packaging materials to meet production needs. The concept of an "electronic level gauge-type glass bottle and can shared filling valve control system" stems from the booming development of craft beer in recent years. Craft beer filling equipment generally requires a small footprint, low output, and high batch sizes. Beer packaging comes in various forms, including glass bottles and cans. The technology of filling various materials, including carbonated and non-carbonated liquids, into bottles, cans, boxes, barrels, or bags using filling valves not only improves productivity, reduces product loss, and ensures packaging quality, but also reduces cross-contamination between the production environment and the filled materials. Currently, filling technology is widely used in automated filling production in pharmaceutical, daily chemical, food, and other specialized industries. To complete the filling process, the filling valve is an essential component. According to the filling principle, filling valves can be divided into atmospheric pressure filling valves, positive pressure filling valves, negative pressure filling valves, or pressurized filling valves. These filling machines all belong to the mechanical filling method, that is, the filling method uses mechanical filling valves to achieve the filling of materials.

[0003] Currently, traditional mechanical filling valves suffer from low capacity accuracy, complex structure, poor overall liquid level control, and low production efficiency. Furthermore, traditional filling valve designs limit their application to specific filling machines used on bottling lines and can lines. This simplistic filling structure significantly restricts filling efficiency, requiring machine shutdown and replacement of the entire valve before resuming the filling process for different types of bottles.

The filling assembly 1 includes a cavity 11, a valve seat 12 mounted on the cavity 11, a valve sleeve 13 passing through the cavity 11 and connecting to the valve seat 12, and a valve stem 14 located within the valve sleeve 13. The cavity structure contains chambers with different functions (not shown), and the valve seat 12 contains a filling channel 122. The upper end of the valve stem 14 extends beyond the valve seat 12 and, from top to bottom, is a connecting pipe support 141, a spring clamping block 142, and a valve sealing spring seat 143.

An interface end (not marked) is located on the outside of the air return channel 1411, and a connecting pipe 1412 is connected to it. The connecting pipe support 141 and the spring clamping block flange 144 are fixedly connected by long screws 8 to form a whole. The wine valve sealing spring seat 143 is fixed to the valve seat 12 by short screws 81. A second strip bearing 1431 is provided between the wine valve sealing spring seat 143 and the wine valve stem 14 to improve the smoothness of the movement of the wine valve stem. A wine valve spring 145 is provided between the spring clamping flange 144 and the wine valve sealing spring seat 143. A cylinder assembly 5 is connected to the upper end of the connecting pipe support 141. A support column 121 is provided on one side of the valve seat 12. The cylinder assembly 5 is fixed on the support column 121, forming an independent fixed unit.

[0033] In this embodiment, the lower part of the valve sleeve 13 narrows inward to form the wine outlet 131, making the overall structure simpler. Under the same structure, it can be adapted to various return gas distributors 7 and centering filling heads 6, greatly improving adaptability. The lower part of the valve rod 14 located inside the valve sleeve 13 is also provided with a valve rod guide block 147. The lower end of the valve rod 14 is adapted to the wine outlet 131 and is provided with a wine outlet sealing gasket 1311, which can seal the wine outlet.

After filling is completed, the centering filling head can be lifted up and removed from the bottle mouth to complete the filling work.

[0040] In this embodiment, the first part is the centering filling head 6 designed for the bottle container opening.

[0041] Working principle: Before filling, the filling head is replaced with a centering filling head suitable for the glass bottle opening. During filling, the bottle inlet mechanism places the container in the preset position. Then, the centering filling head, held by the centering filling head fixing plate, is clamped downwards and forms a sealed space with the bottle opening through the movable centering rod 46. Before filling, the first control valve and the second control valve are used to perform vacuuming, back pressure and other pre-filling processes. After completion, filling begins. First, the cylinder assembly 5 is closed to release the wine valve rod and reset it upwards, thereby opening the sealed wine outlet. At the same time, the measuring cylinder supply valve also opens the corresponding sealed feed port (not marked) to start filling. When the preset filling volume is reached, the cylinder assembly 5 presses the wine valve rod downwards and seals the wine outlet. The measuring cylinder supply valve closes simultaneously. Then, the third control valve and the fourth control valve are used to perform depressurization and other operations. Finally, the bottle is discharged to complete the filling.
