[0001] This utility model relates to the field of filling, and in particular to a volume displacement isobaric quantitative filling system based on a screw adjusting piston. Background Technology
[0002] In today's rapidly developing domestic economy, high-precision, multi-purpose beer bottling equipment has become a key challenge for many domestic beer producers, especially small craft beer companies.
[0003] With the continuous development of the domestic market and the increasing diversification of consumer demands, numerous beer companies, especially small craft beer breweries, need to produce a variety of products with diverse flavors and packaging to meet market demands. However, domestic semi-automatic and even fully automatic small-scale beer bottling equipment, especially linear bottling equipment, often suffers from low production efficiency, high beer loss, low bottling accuracy, and a significant decrease in CO2 content after bottling. Simultaneously, dissolved oxygen levels cannot be effectively controlled. Due to structural issues, the bottling equipment is difficult to clean, and aseptic bottling conditions cannot be achieved during the bottling process. The resulting beer's physicochemical properties fall far short of national standards, leading to unstable taste and various quality problems after entering the market. Therefore, those skilled in the art have provided a volumetric displacement isobaric quantitative bottling system based on a screw-adjustable piston to address the problems mentioned in the background. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a volume displacement isobaric quantitative filling system based on a screw-adjustable piston, comprising: a filling head structure, one end of which is provided with a filling tube for filling the solution, and the other end of which is provided with a filling control cylinder for lifting and lowering the filling head structure to seal the bottle mouth and allow the filling tube to penetrate into the bottle for filling; a wine source interface, which is connected to the filling head structure and conductively connected to the filling tube; and a carbon dioxide backup pressure valve, which is connected to the filling head structure, and the other end of which is connected to a piston screw assembly, wherein the piston screw assembly includes a piston cylinder, the interior of which forms a container air chamber, a sealing piston is provided inside the container air chamber, and an adjusting screw is provided at the top of the container air chamber.
[0006] As a further technical solution of this utility model, it also includes a two-position five-way solenoid valve B, which is connected to the filling control cylinder and drives the telescopic end of the filling control cylinder to move telescopically.
[0007] As a further technical solution of this utility model, it also includes a two-position five-way solenoid valve C, which is connected to the filling head structure and controls the opening and closing of the piston inside the filling head structure.

[0013] This invention provides a volume displacement isobaric quantitative filling system based on a screw-adjusting piston, which has the following advantages compared with the prior art:
[0014] This design utilizes the adjusting screw within the piston-screw assembly to limit the piston's position, enabling the piston to perform quantitative lifting and lowering. When filling the bottle with beer through the beer source interface, the piston's movement displaces carbon dioxide gas within the bottle. As the beer enters the bottle, the carbon dioxide gas is drawn into the container's gas chamber by the piston's upward movement. When the piston reaches the adjusting screw position, the required filling volume is achieved, thus realizing quantitative beer filling. This design solves the problems of beer loss and quantitative filling, as well as the issue of increased dissolved oxygen after beer filling. Furthermore, the filling process does not lose carbon dioxide gas content, and the filling pipeline is easy to clean, maintaining a sterile environment and maximizing the preservation of the beer's original flavor.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-2 This utility model provides a technical solution for a volume displacement isobaric quantitative filling system based on a screw-adjustable piston: The volume displacement isobaric quantitative filling system based on a screw-adjustable piston includes a two-position five-way solenoid valve A1, which is connected to the piston screw assembly 2 and controls the sealing piston 24 to move up and down along the container air chamber 23 to realize the functions of air intake and exhaust in the container air chamber 23.
[0020] The piston screw assembly 2 includes a piston cylinder 21, the interior of which forms a container air chamber 23. A sealing piston 24 is disposed inside the container air chamber 23, and an adjusting screw 22 is disposed at the top of the container air chamber 23.
[0021] By adjusting the screw 22, the movement of the sealing piston 24 is limited, and the position of the sealing piston 24 in the container air chamber 23 is determined, thereby determining the volume of the lower air chamber of the sealing piston 24. This volume is equal to the capacity of the beer bottle 13 to be filled, so as to achieve the purpose of quantitative filling.
[0022] The lower volume of the container air chamber 23 is filled with gas after the gas in the filling bottle 13 is replaced, so that the carbon dioxide gas in the filling bottle 13 is replaced into the container air chamber 23, and the gas in the upper part of the sealing piston 24 is compressed air.
[0023] The sealing piston 24, under certain pressure and sealing conditions inside the container, can move up and down due to the difference in force area and different air pressure differences. It stops when it rises to the adjusting screw 22 and stops when it descends to the bottom of the container's air chamber 23. The movement of the sealing piston 24 replaces the carbon dioxide gas in the filling bottle 13. When the beer enters the filling bottle 13, the carbon dioxide gas in the bottle moves upward through the sealing piston 24 and enters the container's air chamber 23. When the sealing piston 24 reaches the position of the adjusting screw 22, the beer in the bottle reaches the required filling volume, thus achieving the purpose of beer filling.
[0024] The pressure relief control solenoid valve 3 is connected to the piston screw assembly 2. When the beer filling is completed, the sealing piston 24 is in the high position. At this time, the two-position five-way solenoid valve A1 is opened. The valve opens to discharge the carbon dioxide gas in the container gas chamber 23. Under the action of pressure, the sealing piston 24 reaches the bottom of the container and returns to the initial state.
[0025] The two-position five-way solenoid valve B4 is connected to the filling control cylinder 5, driving the telescopic end of the filling control cylinder 5 to extend and retract, controlling the cylinder to rise and fall. The filling head structure 6 is connected to the filling control cylinder 5. At this time, the two-position five-way solenoid valve B4 opens, controlling the filling control cylinder 5 to descend, so that the filling head structure 6 is pressed down to the bottle mouth of the filling bottle 13 for sealing. When the two-position five-way solenoid valve B4 closes, the filling control cylinder 5 rises and the filling head structure 6 disengages from the bottle mouth of the filling bottle 13.
[0026] A filling control cylinder 5 is connected to the filling head structure 6, and the filling head structure 6 is raised and lowered by the cylinder.
[0027] The filling head structure 6 has a filling tube 12 for filling the solution at one end and a filling control cylinder 5 at the other end for lifting and lowering the filling head structure 6. The filling head structure 6 is pushed down to seal the mouth of the filling bottle 13 and allow the filling tube 12 to enter the filling bottle 13 for filling. At the same time, the filling head structure 6 is designed with a carbon dioxide inlet, which is connected to a carbon dioxide pressure relief valve 7 for the intake and exhaust of carbon dioxide in the filling bottle 13. The filling head structure 6 also has a pressure relief port, which is connected to an internal pressure relief valve 11 for depressurizing the bottle after the filling bottle 13 is filled with wine. The filling head structure 6 also has a wine inlet, which is connected to the filling tube 12. A piston is also located inside the filling head structure 6, which is connected to a two-position five-way solenoid valve C9 for controlling the wine inlet switch.
[0028] The carbon dioxide backup pressure valve 7 is connected to the filling head structure 6, and the other end of the carbon dioxide backup pressure valve 7 is connected to the piston screw assembly 2. This valve is opened when carbon dioxide is back pressured to the filling bottle 13 before beer filling, and closed after beer filling is completed.
[0029] The carbon dioxide master control valve 8 is located between the carbon dioxide backup valve 7 and the piston screw assembly 2. This valve is opened when carbon dioxide is prepared for filling the bottle 13 before beer filling and closed after beer filling is completed.
[0030] The two-position five-way solenoid valve C9 is connected to the filling head structure 6 and controls the opening and closing of the piston inside the filling head structure 6, thereby controlling the filling of the bottle 13 or shutting off the liquid.
[0031] The wine source interface 10 is connected to the filling head structure 6 and is conductively connected to the filling pipe 12. The wine source interface 10 can be connected to the wine tank or the main wine pipeline. In this way, when the piston in the filling head structure 6 is opened, the wine can directly enter the filling bottle 13.
[0032] The bottle pressure relief valve 11 is connected to the filling head structure 6. When the beer filling in the filling bottle 13 is completed and other valves are closed, this valve opens to release the pressure inside the bottle.
[0033] The filling tube 12 is connected to the filling head structure 6. When the wine source interface 10 is opened, the wine flows out from the bottom of the tube and enters the filling bottle 13.
[0034] The working principle of this utility model includes the following steps:
[0035] Step 1: Open the two-position five-way solenoid valve A1 to ensure that the sealing piston 24 reaches the bottom of the container, and all other valves are closed. At the same time, the gas pressure in the two-position five-way solenoid valve A1 is equal to the gas pressure in the carbon dioxide main control valve 8 and the wine source interface 10.
[0036] Step 2: Determine that the filling bottle 13 to be filled has reached the filling position.
[0037] Step 3: The two-position five-way solenoid valve B4 is opened, and the filling control cylinder 5 drives the filling head structure 6 to press down to the bottle mouth of the filling bottle 13 to seal the bottle mouth.
[0038] Step 4: The main carbon dioxide control valve 8 and the carbon dioxide backup valve 7 are opened simultaneously. After a specified time, the main carbon dioxide control valve 8 is closed. In this way, carbon dioxide enters the filling bottle 13 and is in communication with the container gas chamber 23 through the pipeline.
[0039] Step 5: Open the two-position five-way solenoid valve C9 of the wine source.
[0040] Step Six: Close the two-position five-way solenoid valve A1. At this time, the pressure in the container's gas chamber 23 will be slowly released to the outside through the two-position five-way solenoid valve A1. In this way, the wine will quickly enter the bottom of the filling bottle 13 through the filling tube 12. At the same time, the carbon dioxide in the filling bottle 13 will enter the container's gas chamber 23 through the carbon dioxide pressure reserve valve 7. Under the action of the gas source pressure difference and the force area difference, the sealing piston 24 will rise. When the sealing piston 24 rises to the bottom of the adjusting screw 22, the two-position five-way solenoid valve C9 will close, and the filling process will end.
[0041] Step 7: After filling is completed, the carbon dioxide pressure relief valve 7 is closed and the pressure relief valve 11 inside the bottle is opened to release the pressure inside the filling bottle 13. At the same time, the two-position five-way solenoid valve A1 connected to the gas chamber 23 of the container is opened, the pressure relief control solenoid valve 3 is opened, and the sealing piston 24 is lowered to the bottom of the container, returning to the initial state.
[0042] Step 8: After the above process is completed, the two-position five-way solenoid valve B4 is closed, and the filling control cylinder 5 drives the filling head structure 6 and the filling tube 12 to rise synchronously, so that the filling tube 12 is separated from the bottle mouth of the filling bottle 13.
[0043] Step 9: Through the above process, by using isobaric pressure and displacement of the same volume in different containers, the beer bottling effect is achieved.
[0044] In conclusion, for equipment manufacturers, this technology solves the problem of slow beer bottling efficiency, increasing production efficiency by at least 2-3 times compared to conventional bottling equipment. It also solves the problems of beer loss and precise filling, significantly improving filling accuracy. The filling accuracy of a single bottle can be controlled within 3 grams, with near-zero beer loss, and the filling capacity can be arbitrarily set and adjusted according to needs. Furthermore, it addresses the issue of increased dissolved oxygen after beer bottling. Because the beer enters the bottle directly during the bottling process without intermediate transition materials or contact with external oxygen, this technology greatly reduces dissolved oxygen levels. This technology increases oxygen levels and prevents the loss of carbon dioxide in the liquor during bottling. Through gas displacement during bottling, the piston prevents the liquor from communicating with the outside environment, thus preventing carbon dioxide release and ensuring no loss of carbon dioxide content. Furthermore, the pipelines are easy to clean and can achieve a sterile environment for bottling. Compared to other equipment, this design offers multiple uses, significantly reducing production costs and making it widely applicable in industries such as beer, spirits, beverages, carbonated drinks, pharmaceuticals, and dairy products.
[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
