Description

Technical Field

[0001] This utility model relates to the field of beverage filling technology, specifically to a vacuum filling device for liquid beverages. Background Technology

[0002] Filling processed food materials into various containers is one of the main steps in food production. Currently, there are many types of filling machines available. If classified according to the nature of the material, they can be roughly divided into liquid filling machines, sauce filling machines, solid filling machines, etc. Vacuum devices refer to devices that remove air from the inside of the packaging to achieve a predetermined vacuum level, and then fill the container with liquid through pressure difference.

[0003] The existing Chinese utility model patent with publication number CN204251304U discloses a vacuum beverage filling device, which includes a base, a main shaft, a beverage box, a liquid inlet pipe, a float, a bottle holder, a gas valve, a vacuum tube, a compression spring, and a sealing ring. The beverage box is supported by the main shaft, and the lower end of the main shaft is connected to the base. The bottle holder is slidably connected to the base via a sliding rod. A vacuum tube is provided at the top of the beverage box. The liquid inlet pipe extends into the beverage box from the top, and the bottom of the liquid inlet pipe is closed, with a radial liquid inlet hole in the middle. The float is located in the beverage box and is sleeved on the liquid inlet pipe. A liquid injection pipe is provided at the bottom of the beverage box, and a liquid valve is provided on the liquid injection pipe. The compression spring is sleeved on the lower end of the liquid injection pipe, and the lower end of the compression spring is connected to the sealing ring. The sealing ring is positioned below the lowest end of the liquid injection pipe, and its upper end is connected to the liquid injection pipe. An air extraction pipe is sleeved inside the liquid injection pipe, and a gas valve is provided at the upper end of the air extraction pipe. The vacuum beverage filling device of this application can eliminate gas residue in beverage bottles, thereby extending the shelf life of beverages.

[0004] Existing vacuum devices may draw liquid from the bottle into the device during use, affecting the actual filling quality of the beverage. Furthermore, existing vacuum devices require restricting the position of the bottle to align the bottle opening with the air inlet pipe, which is very inconvenient. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a liquid beverage filling vacuum device, comprising: a base plate, a limiting ring fixedly installed on the top of the base plate, a vacuum pump fixedly installed on the top of the base plate, a hose fixedly installed on the top of the vacuum pump, a support frame fixedly installed on the top of the base plate, a pressing piston fixedly installed at the top of the support frame, a connecting plate fixedly installed below the pressing piston, a connecting column inserted above the connecting plate, a spring inserted on the outer side of the connecting column, a movable frame fixedly installed at the bottom of the connecting column, a limiting tube fixedly installed at the center of the movable frame, an air chamber fixedly installed at the center of the connecting plate, a silicone plate fixedly installed at the top of the air chamber, and an adapter pipe fixedly installed at the top of the air chamber; the vacuum pump is capable of extracting air from inside the hose.

[0009] As a preferred technical solution of this utility model, the left side of the base plate is provided with an annular recess that fits into the limiting ring, and the top end of the hose is fixedly connected to the right end of the adapter tube; the hose can adapt to the position change of the gas chamber while connecting the adapter tube and the vacuum pump.

[0010] As a preferred embodiment of this utility model, the downward piston support frame is symmetrically installed on the front and rear sides of the top of the support frame with the center as the reference, and the downward piston points vertically downward toward the bottom plate; the downward piston can drive the connecting plate to move.

[0011] As a preferred embodiment of this utility model, the center of the connecting plate is provided with an annular structure that matches the air chamber, and the connecting plate is movably connected to the support frame through a pressing piston; the connecting plate can restrict the position of the air chamber.

[0012] As a preferred embodiment of this utility model, the connecting column is symmetrically installed on the front and rear sides of the connecting plate with the center of the connecting plate as the reference. The top of the connecting column is provided with an annular protrusion structure, and the connecting column and the connecting plate form a sliding connection. The connecting column can restrict the movement direction of the movable frame.

[0013] As a preferred embodiment of this utility model, the spring is located between the connecting plate and the movable frame, the movable frame is movably connected to the connecting plate through the connecting column, and the cavity of the limiting tube has a conical structure; the spring can apply a downward force to the movable frame when it contracts.

[0014] As a preferred embodiment of this utility model, the inner diameter of the bottom end of the limiting tube cavity is consistent with the inner diameter of the limiting ring, and the limiting tube is located directly above the limiting ring. The bottom end of the air cavity is provided with a disc-shaped protrusion structure, and the upper and lower ends of the air cavity are conical structures. The top end of the air cavity is connected to the hose through an adapter pipe. The adapter pipe facilitates the connection between the air cavity and the hose.

[0015] Compared with the prior art, the present invention provides a vacuum filling device for liquid beverages, which has the following beneficial effects:

[0016] 1. This utility model utilizes a limiting tube, which is fixedly installed at the center of a movable frame. The movable frame is movably installed below the connecting plate via a connecting column. A spring is located between the connecting plate and the movable frame. The cavity of the limiting tube has a conical structure, with the inner diameter of the bottom end of the limiting tube cavity matching the inner diameter of the limiting ring. The limiting tube is positioned directly above the limiting ring. When the piston is pressed down, causing the connecting plate to move downward, the limiting tube contacts the container first. When the container contacts the inner cavity of the limiting tube, friction causes the spring to compress. The downward force exerted by the spring on the movable frame during compression guides the container to the exact center of the limiting tube as it moves downward, thus positioning the container opening directly below the air chamber. This method reduces the need to adjust the container position, facilitating subsequent operations.

[0017] 2. This utility model features an air chamber, which is fixedly installed at the center of the connecting plate. The upper and lower ends of the air chamber are conical structures. The top of the air chamber is connected to the hose via an adapter. The silicone plate fixedly installed below the air chamber provides a sealing function. When the vacuum pump is started, the air inside the air chamber can be extracted through the hose and adapter. Due to the influence of the internal tubular structure of the air chamber, the liquid will remain inside the air chamber after entering it, and will flow back into the container through the conical structure at the bottom of the air chamber after the vacuum pump stops working. This method can prevent the liquid from entering the adapter during the vacuuming process, thus avoiding a reduction in the mass of the liquid in the container. Attached Figure Description

[0027] The left side of the base plate 1 has an annular recess that fits into the limiting ring 11. The top end of the hose 13 is fixedly connected to the right end of the adapter pipe 113. The lower piston 15 is symmetrically installed on the front and rear sides of the top of the support frame 14 with the center as the reference. The lower piston 15 points vertically downward toward the base plate 1. The center of the connecting plate 16 has an annular structure that matches the air chamber 111. The connecting plate 16 is movably connected to the support frame 14 through the lower piston 15. The connecting column 17 is symmetrically installed on the front and rear sides of the connecting plate 16 with the center as the reference. The top end of the connecting column 17... A ring-shaped protrusion structure is provided. The connecting column 17 and the connecting plate 16 form a sliding connection. The spring 18 is located between the connecting plate 16 and the movable frame 19. The movable frame 19 is movably connected to the connecting plate 16 through the connecting column 17. The cavity of the limiting tube 110 has a conical structure. The inner diameter of the bottom end of the limiting tube 110 cavity is the same as the inner diameter of the limiting ring 11. The limiting tube 110 is located directly above the limiting ring 11. The bottom end of the air cavity 111 is provided with a disc-shaped protrusion structure. The upper and lower ends of the inner cavity of the air cavity 111 have conical structures. The top end of the air cavity 111 is connected to the hose 13 through the adapter pipe 113.

[0028] Specifically, the base plate 1 supports the vacuum pump 12, the limiting ring 11 restricts the position of the container, the vacuum pump 12 extracts air from the inside of the hose 13, the hose 13 adapts to changes in the position of the air chamber 111 while connecting the adapter 113 and the vacuum pump 12, the support frame 14 restricts the position of the top of the pressing piston 15, the pressing piston 15 drives the connecting plate 16 to move, the connecting plate 16 restricts the position of the air chamber 111, the connecting column 17 restricts the direction of movement of the movable frame 19, the spring 18 applies a downward force to the movable frame 19 when it contracts, the movable frame 19 restricts the position of the limiting tube 110, the limiting tube 110 changes the position of the container so that the container is directly below the air chamber 111, the air chamber 111 prevents liquid from entering the inside of the adapter 113, the silicone plate 112 provides a sealing function, and the adapter 113 facilitates communication between the air chamber 111 and the hose 13.

[0029] In use, the limiting tube 110 is fixedly installed at the center of the movable frame 19. The movable frame 19 is movably installed below the connecting plate 16 via the connecting column 17. The spring 18 is located between the connecting plate 16 and the movable frame 19. The cavity of the limiting tube 110 has a conical structure. The inner diameter of the bottom end of the limiting tube 110 cavity is the same as the inner diameter of the limiting ring 11, and the limiting tube 110 is located directly above the limiting ring 11. When the pressing piston 15 drives the connecting plate 16 to move downward, the limiting tube 110 contacts the container first. When the container contacts the inner cavity of the limiting tube 110, the spring 18 will be compressed due to friction. Through the downward force exerted by the spring 18 on the movable frame 19 during compression, the inner wall of the limiting tube 110 will guide the container to the exact center of the limiting tube 110 as the limiting tube 110 moves downward, thereby positioning the container mouth in the gas chamber 111. Directly below, this method reduces the need to adjust the container position, facilitating subsequent operations. The air chamber 111 is fixedly installed at the center of the connecting plate 16. The upper and lower ends of the inner cavity of the air chamber 111 are conical structures. The top of the air chamber 111 is connected to the hose 13 through the adapter 113. The silicone plate 112 fixedly installed below the air chamber 111 can play a sealing role. When the vacuum pump 12 is started, the air inside the air chamber 111 can be extracted through the hose 13 and the adapter 113. Due to the influence of the internal tube structure of the air chamber 111, the liquid will stay inside the air chamber 111 after entering it, and will flow back into the container through the conical structure at the bottom of the air chamber 111 after the vacuum pump 12 stops working. This method can prevent the liquid from entering the adapter 113 during the vacuuming process, which would reduce the mass of the liquid in the container.
