Description

Technical Field

[0001] This invention relates to the field of carbonated beverage filling technology, and more particularly to a carbonated beverage filling valve control device. Background Technology

[0002] Existing beverage filling machines typically consist of a flow meter, filling pipe, and filling head. The filling process usually involves the liquid flowing directionally through the pipe, the flow meter determining the amount of fluid to be filled each time, and the filling head concentrating the liquid and filling it into the bottle.

[0003] When carbonated beverages are bottled, a lot of foam is produced after the beverage enters the container, which causes a large amount of carbon dioxide to be released. This results in insufficient carbon dioxide content in the carbonated beverage, making the finished carbonated beverage less refreshing.

[0004] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carbonated beverage filling valve control device. This device, in addition to filling the bottle with the slurry, can also inject carbon dioxide into the bottle through a specially designed pneumatic control valve module. It has a long service life and does not contaminate the carbonated beverage. Its simple structure and easy manufacturing process ensure sufficient carbon dioxide content in the carbonated beverage, resulting in a refreshing and palatable finished product, making it suitable for widespread application in the industry.

[0006] To achieve the above-mentioned objectives, the carbonated beverage filling valve control device proposed in this invention is implemented through the following technical solution:

[0008] The piston has an annular groove on its circumference and a sealing ring is fitted therein; the center of the first end face of the piston has a circular hole for inserting the piston rod, and the outer edge of its second end face has several notches that connect to the annular groove.

[0009] The annular groove includes a vertical surface, a bottom surface, a step, and a slope, wherein: the vertical surface is located on one side of the first end face and is an annular shape perpendicular to the circular hole; the bottom surface is a cylindrical surface parallel to the circular hole; the step is located on the other side of the bottom surface opposite to the vertical surface and is a step shape lower than the vertical surface along the cross section of the annular groove; the slope is shaped like a frustum, with its bottom located on one side of the second end face and its top connected to the step; the notch is formed between the bottom of the slope and the second end face.

[0016] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The terms used in this specification, such as "front," "back," "left," "right," "inner," and "outer," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of the invention.

[0018] In the description of the following embodiments, unless otherwise expressly specified and limited, the term "connection" and other such terms should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] See Figure 1-2 As shown in the figure, this embodiment of the invention proposes a carbonated beverage filling valve control device, including a filling valve assembly 1, a filling pipe 3, a filling head 2, a cylinder 4, and a bottle lifting mechanism 5. The bottle lifting mechanism 5 can hold the bottle mouth and lift it upward under the drive of the cylinder 4, at which time the filling head 2 is inserted into the bottle mouth for filling.

[0020] A slurry channel is formed inside the filling pipe 3, and a threaded guide groove is provided on its outer wall.

[0021] The filling valve assembly 1 has a slurry interface for connecting the slurry inlet pipe and can selectively connect the filling pipe 3 and the slurry interface.

[0022] The filling valve assembly 1 is also equipped with a pneumatic control valve module 6. The pneumatic control valve module 6 is equipped with a control chamber 61, a carbon dioxide chamber 62, and a piston 63 that can slide in the control chamber 61.

[0023] The control chamber 61 has a high-pressure gas control interface, including a high-pressure gas inlet 611 and a high-pressure gas outlet 612.

[0024] The carbon dioxide chamber 62 has an inlet 621 and an outlet 622 connecting to the filling pipe 3. A valve core 64 is movably mounted in the carbon dioxide chamber 62 for opening and closing the carbon dioxide flow channel between the inlet 621 and the outlet 622. The carbon dioxide chamber 62 also has a first spring 623 that biases the valve core 64 towards the closed position of the carbon dioxide flow channel. Since this structure is a conventional structure for a fluid control valve, its specific structure will not be described in detail here.

[0025] The piston rod 65 is centrally connected to the piston 63. For example... Figure 3-4As shown, the piston 63 is generally cylindrical, with an annular groove on its circumference and a sealing ring 631 embedded therein. The center of the first end face of the piston 63 has a circular hole 632 for inserting the piston rod 65, and the outer edge of its second end face has several notches 633 evenly distributed to connect to the annular groove. In a preferred embodiment, the annular groove includes a vertical surface 634, a bottom surface 635, a step 636, and a slope 637, wherein: the vertical surface 634 is located on one side of the first end face and is annularly shaped perpendicular to the circular hole 632; the bottom surface 635 is a cylindrical surface parallel to the circular hole 632; the step 636 is located on the other side of the bottom surface 635 opposite to the vertical surface 634, and is a step lower than the vertical surface 634 along the cross-section of the annular groove; the slope 637 is frustum-shaped, with its bottom located on one side of the second end face and its top connected to the step 636; and the notches 633 are formed between the bottom of the slope 637 and the second end face. Therefore, when high-pressure gas is introduced into the control chamber 61, its internal pressure increases. The high-pressure gas in the control chamber 61 contacts the sealing ring 631 via the notch 633, slope 637, and step 636, causing the sealing ring 631 to abut against the vertical surface 634 and its outer circumference to fully contact the cylinder wall of the control chamber 61. This ensures the airtightness of the control chamber 61 even if the sealing ring 631 wears down over long-term use. This not only significantly extends the life of the sealing ring and reduces maintenance costs, but also prevents the high-pressure gas in the control chamber 61 from mixing with carbon dioxide, thus avoiding contamination of carbonated beverages.

[0026] The piston rod 65 has a circular bottom surface 651 and a rod body 652 located at the center of the circular bottom surface 651. The rod body 652 is inserted into the circular hole 632, and the other side of the circular bottom surface 651 opposite to the rod body 652 is connected to the valve core 64 through a second spring 653.

[0027] Therefore, when high-pressure gas is introduced into the control chamber 61, the piston 63 slides along the control chamber 61, pushing the valve core 64 to move, thus opening the carbon dioxide flow passage between the inlet 621 and the outlet 622. When the high-pressure gas is discharged from the control chamber 61, the pressure in the control chamber 61 returns to normal. The first spring 623 pushes the valve core 64 to close the carbon dioxide flow passage between the inlet 621 and the outlet 622, and the second spring 653 further pushes the piston rod 65 and the piston 63, causing the piston 63 to return to its original position.

[0028] Compared with existing technologies, the advantages of this invention are as follows: This invention proposes a carbonated beverage filling valve control device. In addition to filling the bottle with slurry, this device can also inject carbon dioxide into the bottle through a specially designed pneumatic control valve module. It has a long service life and does not cause contamination of the carbonated beverage.
