Description

Technical Field

[0001] The utility model relates to the technical field of filling, and particularly relates to a filling mechanism compatible with containers of large and small apertures. Background Art

[0002] From brewing to sales, there are many filling processes for beer. The beer brewing process has been in a closed space, and carbon dioxide is continuously generated during the fermentation process. This process will increase the pressure in the closed space, thereby dissolving more carbon dioxide into the liquor. During the filling process, due to pressure changes, friction between the liquor and the pipeline, and temperature changes between two containers, the carbon dioxide in the liquor will be released, resulting in a large amount of foam. Pressure change is the biggest reason for generating foam. Therefore, isobaric filling technology is mostly used in the industry to solve the foam problem.

[0003] The Chinese utility model patent document with the publication number of CN219689321U discloses an isobaric filling mechanism, which includes a filling head, a lifting component fixed on the filling head, and a moving component arranged below the filling head. The beverage container is placed on or hung on the moving component, and the lifting end of the lifting component is connected to the moving component and drives the moving component to lift. The characteristics are that it further includes a weighing substrate, a cantilever beam weighing sensor, and a weighing support. The lifting component and the stress end of the cantilever beam weighing sensor are fixed on the weighing substrate, and the fixed end of the cantilever beam weighing sensor is fixed on the weighing support. This isobaric filling mechanism can perform isobaric filling on beer containers to reduce the foam generated during the beer filling process.

[0045] Please refer to Figures 1 to 10 , this embodiment provides a filling mechanism compatible with containers of different sizes, including a filling head 1, a lifting assembly 2, a moving assembly 3, a weighing substrate 4, a cantilever beam weighing sensor 5, and a weighing bracket 6. The moving assembly 3 is arranged below the filling head 1, and the container is placed on or hung on the moving assembly 3. The lifting end of the lifting assembly 2 is connected to the moving assembly 3 and drives the moving assembly 3 to lift. The filling head 1, the lifting assembly 2, and the force-receiving end of the cantilever beam weighing sensor 5 are all fixed on the weighing substrate 4, and the fixed end of the cantilever beam weighing sensor 5 is fixed on the weighing bracket 6. The weighing bracket 6 is used to be fixed to an external cabinet or a bottom plate. By suspending the filling mechanism as a whole on the cantilever beam weighing sensor 5, during use, the filling head 1 is connected to an external beverage can and an exhaust and drainage pipe, the container is placed on or hung on the moving assembly 3, and the opening of the container is connected to the filling head 1 through the lifting assembly 2, so as to achieve the purpose of synchronous weighing during container filling; in addition, due to the high detection accuracy of the cantilever beam weighing sensor 5 and the fact that it is not affected by the external environment, accurate control of the liquid discharge flow rate and flow velocity is achieved, and the problem of wasting a large amount of beverages during the machine debugging stage is avoided.

[0046] The filling head 1 includes a filling main body 11, a cup plug 12, a bottle plug 13, a first filling seal disc 14 and a second filling seal disc 15. The first filling seal disc 14 is arranged on the periphery of the filling main body 11, and the second filling seal disc 15 is arranged on the periphery of the bottle plug 13.

[0047] An exhaust and liquid discharge joint 16 for connecting an exhaust and liquid discharge pipe and an air inlet and liquid inlet joint 17 for connecting a beverage can and a gas source are provided at the upper end of the filling main body 11. An installation cavity 111 is provided in the middle of the bottom of the filling main body 11. A plurality of first liquid outlets 112 distributed circumferentially are arranged on the outer wall of the bottom of the filling main body 11. The installation cavity 111 is respectively communicated with the exhaust and liquid discharge joint 16, the air inlet and liquid inlet joint 17 and the first liquid outlets 112.

[0048] The cup plug 12 is provided with a first exhaust and liquid discharge port 1221 that penetrates up and down. When the cup plug 12 is installed in the installation cavity 111, the first exhaust and liquid discharge port 1221 is communicated with the exhaust and liquid discharge joint 16. The outer wall of the cup plug 12 and the inner wall of the installation cavity 111 form a first liquid inlet and air inlet cavity 18 that communicates a plurality of first liquid outlets 112 with the air inlet and liquid inlet joint 17. When the opening of the container is pushed against the first filling seal disc 14 by the lifting assembly 2, the first exhaust and liquid discharge port 1221 and the first liquid outlets 112 can be surrounded within the opening to prevent air leakage at the opening during the filling process, thus avoiding the generation of a large amount of foam.

[0049] The bottle plug 13 is provided with a second exhaust and liquid discharge port 1331 that penetrates up and down. A plurality of second liquid outlets 134 distributed circumferentially are arranged on the outer wall of the bottom of the bottle plug 13. When the bottle plug 13 is installed in the installation cavity 111, the outer wall of the bottle plug 13 blocks a plurality of first liquid outlets 112. The second exhaust and liquid discharge port 1331 is communicated with the exhaust and liquid discharge joint 16, and a plurality of second liquid outlets 134 are communicated with the air inlet and liquid inlet joint 17. And the second filling seal disc 15 is located at the bottom of the filling main body 11. When the opening of the container is pushed against the second filling seal disc 15 by the lifting assembly 2, the second exhaust and liquid discharge port 1331 and the second liquid outlets 134 can be surrounded within the opening to prevent air leakage at the opening during the filling process, thus avoiding the generation of a large amount of foam.

[0050] By setting the replaceable cup plug 12 and bottle plug 13, the filling head 1 can adapt to containers with different caliber sizes. Whether it is a cup-shaped container with a large caliber or a bottle-shaped container with a small caliber, filling can be achieved by replacing the corresponding components, greatly improving the versatility and flexibility of the filling mechanism. For example, when the opening caliber of the container (such as a cup-shaped container) is large, the cup plug 12 is selected to be installed on the installation cavity 111 of the filling main body 11, and filling is carried out using the first liquid outlet 112 on the filling main body 11 and the first exhaust and liquid discharge port 1221 on the cup plug 12; when the opening caliber of the container (such as a bottle-shaped container) is small, the bottle plug 13 is selected to be installed on the installation cavity 111 of the filling main body 11, and filling is carried out using the second liquid outlet 134 and the second exhaust and liquid discharge port 1331 of the bottle plug 13, and the diameter of the bottle plug 13 is smaller than the diameter of the filling main body 11.

[0051] It should be noted that although the cup-shaped container can be filled with the bottle plug 13 with a smaller diameter, since the distance between the second liquid outlet 134 of the bottle plug 13 and the inner wall of the cup-shaped container is large, the liquid sprayed from the second liquid outlet 134 will slide down a certain distance before contacting the inner wall of the cup-shaped container. This will cause the liquid sprayed to directly hit the liquid level in the container before the cup-shaped container is filled with liquid, resulting in foam. Therefore, it is necessary to replace the cup plug 12 and use the first liquid outlet 112 on the filling main body 11 and the first exhaust and liquid discharge port 1221 on the cup plug 12 to fill the cup-shaped container to avoid foam generation.

[0052] Please refer to Figures 5 to 7, in one embodiment, an exhaust and drain channel 113 that penetrates up and down is provided at the top of the installation cavity 111. The cup plug 12 includes a cup plug body 121 and a cup plug screw 122. The cup plug body 121 is provided with a first screw through hole 1211 that penetrates up and down, and the cup plug screw 122 is provided with a first exhaust and drain port 1221 that penetrates up and down. The cup plug screw 122 is inserted into the first screw through hole 1211 from bottom to top, and the upper end of the cup plug screw 122 extends upward out of the first screw through hole 1211. When installing the cup plug 12, first insert the cup plug body 121 into the installation cavity 111, and then insert the cup plug screw 122 along the first screw through hole 1211 of the cup plug body 121, so that the upper end of the cup plug screw 122 is threadedly connected to the lower end of the exhaust and drain channel 113. After tightening, the installation of the cup plug 12 is completed. After the cup plug 12 is installed in the installation cavity 111, the exhaust and drain joint 16 is communicated with the first exhaust and drain port 1221 through the exhaust and drain channel 113. The outer wall of the cup plug body 121 and the inner wall of the installation cavity 111 form a first liquid and gas inlet cavity 18. The liquid and gas inlet joint 17 is communicated with a plurality of first liquid outlet ports 112 through the first liquid and gas inlet cavity 18. The above cup plug 12 is fixed by the combined structure of the cup plug body 121 and the cup plug screw 122, and the threaded connection is used to achieve fixation, making the installation and disassembly of the cup plug 12 simple and fast, facilitating the daily maintenance and replacement of the equipment, and reducing the maintenance cost and time.

[0053] Please refer to Figures 5 to 7 , in one embodiment, a first seal 123 is sleeved on the outer wall of the lower end of the cup plug body 121, and a second seal 124 surrounding the first screw through hole 1211 is provided at the top of the cup plug body 121.

The stopper screw 133 penetrates into the second screw through hole 1311 from bottom to top, and the upper end of the stopper screw 133 extends upward out of the second screw through hole 1311. When installing the stopper 13, first insert the second stopper member 132 into the installation cavity 111, then sleeve the first stopper member 131 inside the second stopper member 132, and then insert the stopper screw 133 along the second screw through hole 1311 of the first stopper member 131, so that the upper end of the stopper screw 133 is threadedly connected to the lower end of the exhaust and drainage channel 113. After tightening, the installation of the stopper 13 can be completed. After the stopper 13 is installed, the outer wall of the second stopper member 132 seals a plurality of first liquid outlets 112. The exhaust and drainage joint 16 is communicated with the second exhaust and drainage port 1331 through the exhaust and drainage channel 113. The plurality of second liquid outlets 134 are communicated with the exhaust and drainage joint 16 through the second liquid inlet and air inlet cavity 135. The above-mentioned stopper 13 is fixed by the combined structure of the first stopper member 131, the second stopper member 132 and the stopper screw 133, and the threaded connection is used to realize the fixation, making the installation and disassembly of the stopper 13 simple and fast, facilitating the daily maintenance and replacement of the equipment, and reducing the maintenance cost and time. The setting of the second stopper member 132 not only seals the first liquid outlet 112 to prevent liquid or gas from going out through the first liquid outlet 112, but also provides an installation position for the second filling and sealing disc 15, and at the same time can cooperate with the first stopper member 131 to form the second liquid outlet 134 and the second liquid inlet and air inlet cavity 135 to realize the filling of the bottled container.
