Description

Technical Field

[0001] The utility model relates to the technical field of filling, and particularly relates to a sealing structure of a filling seat. 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, including 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. 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 also includes a weighing substrate, a cantilever beam weighing sensor, and a weighing bracket. 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 bracket. This isobaric filling mechanism can perform isobaric filling on beer containers of different specifications to reduce the foam generated during the beer filling process.

[0004] However, after the above isobaric filling mechanism is installed in the cabinet of the filling equipment, in order to avoid the filling fixing plate of the cabinet affecting the weighing of the isobaric filling mechanism, there will be a certain gap between the filling fixing plate of the cabinet and the weighing substrate of the isobaric filling mechanism, resulting in that the traditional water flushing method cannot be directly carried out and can only rely on wiping with a rag. This not only has low efficiency but also may not be able to clean thoroughly, increasing the hygiene hidden danger; in addition, this gap will also affect the sealing performance of the cabinet, causing dust and water to easily enter the interior along the gap, posing a potential threat to the normal operation of the filling equipment and the quality of beer.

[0029] Please refer to Figures 1 to 5 , this embodiment provides a filling seat sealing structure, which is applied to the cabinet of a filling device. The filling seat sealing structure includes a filling fixing plate 1 and a filling seat 2 installed on the filling fixing plate 1. The filling seat 2 includes a filling head 201, a lifting assembly 202, a moving assembly 203, a weighing substrate 204, a cantilever beam weighing sensor 205, a weighing bracket 206, and a soft rubber seal 207. The moving assembly 203 is arranged below the filling head 201. The lifting end of the lifting assembly 202 passes through the opening of the filling fixing plate 1 and is connected to the moving assembly 203 to drive the moving assembly 203 to lift; the filling head 201, the lifting assembly 202, and the force-receiving end of the cantilever beam weighing sensor 205 are all fixed on the weighing substrate 204, and the fixed end of the cantilever beam weighing sensor 205 is fixed on the filling fixing plate 1 through the weighing bracket 206; there is a gap between the filling fixing plate 1 and the weighing substrate 204, and the soft rubber seal 207 is arranged at the bottom of the weighing substrate 204 to block the gap.

[0030] By suspending the entire filling base 2 on a cantilever beam load cell 205, during use, connect the filling head 201 to an external beverage can and the exhaust and drain pipes. Place or hang the container on the moving component 203, and use the lifting component 202 to connect the opening of the container to the filling head 201, thereby achieving the purpose of synchronous weighing during container filling. Since the cantilever beam load cell 205 has high detection accuracy and is not affected by the external environment, it realizes precise control of the liquid discharge flow rate and velocity, avoiding the problem of wasting a large amount of beverages during the machine debugging stage. Additionally, by setting a soft rubber seal 207 to block the gap between the filling fixing plate 1 and the weighing substrate 204, it not only does not affect the normal filling and weighing processes, but also significantly improves the sealing performance of the cabinet, preventing adverse factors such as external dust and moisture from affecting the filling equipment and the filling process, making the cleaning of the filling head 201 more convenient and thorough, and ensuring the cleanliness of the filling environment and the hygienic quality of the product.

[0031] Please refer to Figures 1 to 5 , in one embodiment, the soft rubber seal 207 includes a fixed outer ring 2071, a fixed inner ring 2072, and a deformation groove 2073 provided between the fixed outer ring 2071 and the fixed inner ring 2072. The fixed outer ring 2071 is fixed to the filling fixing plate 1, and the fixed inner ring 2072 is fixed to the weighing substrate 204. The fixed connection of the fixed outer ring 2071 to the filling fixing plate 1 and the fixed connection of the fixed inner ring 2072 to the weighing substrate 204 together form a sealed boundary. This boundary, through the elastic characteristics of the soft rubber seal 207, closely adheres between the two fixed surfaces, thereby effectively preventing liquid, dust, or other contaminants from penetrating through the gap.

[0032] Specifically, a support frame 208 is provided at the bottom of the weighing support 206. The support frame 208 is fixed to the filling fixing plate 1. An outer ring fixing member 209 that surrounds the weighing substrate 204 is provided at the bottom of the support frame 208. The fixed outer ring 2071 is fixed to the bottom of the outer ring fixing member 209, and the bottom surface of the fixed outer ring 2071 presses on the top surface of the filling fixing plate 1 to block the gap between the filling fixing plate 1 and the weighing substrate 204. Through the above settings of the support frame 208 and the outer ring fixing member 209, the filling base 2 (the lifting component 202, the moving component 203, the weighing substrate 204, the cantilever beam load cell 205, the weighing support 206, and the soft rubber seal 207, etc.) can be detached from the filling fixing plate 1 as a whole. It only needs to remove the connection between the support frame 208 and the filling fixing plate 1, making the maintenance, cleaning, replacement, or upgrade of the equipment more convenient and fast, reducing the maintenance cost and time cost.

[0033] Please refer to Figure 4 , Figure 5, in one embodiment, a plurality of first fixing posts 20711 are circumferentially arranged at the top of the fixed outer ring 2071, and a plurality of first fixing holes 2091 that cooperate with the first fixing posts 20711 are circumferentially arranged at the bottom of the outer ring fixing member 209. Through the cooperation of the first fixing posts 20711 and the first fixing holes 2091, a rapid and accurate connection between the fixed outer ring 2071 and the outer ring fixing member 209 is achieved, simplifying the installation process, improving the assembly efficiency, and at the same time ensuring the firmness of the connection.

[0034] Please refer to Figures 1 to 5 , in one embodiment, the four corners of the support frame 208 are fixed to the filling fixing plate 1 through wing nuts 210. The wing nuts 210 are easy to manually tighten and loosen, and installation and adjustment can be carried out without special tools, greatly facilitating the maintenance and upgrade of the equipment.

[0035] Please refer to Figures 2 to 5 , in one embodiment, a filling sealing disc 211 is arranged around the filling head 201. The filling sealing disc 211 is fixed to the bottom of the weighing substrate 204. A food-grade silicone sealing gasket 2111 that surrounds the filling head 201 is provided at the bottom of the filling sealing disc 211. The fixed inner ring 2072 is fixed to the bottom of the filling sealing disc 211 through an inner ring silicone pressing plate 212. The combination of the filling sealing disc 211 and the food-grade silicone sealing gasket 2111 ensures a good seal between the filling head 201 and the beverage can, preventing leakage and contamination during the filling process.

[0036] Specifically, a plurality of second fixing posts 2121 are circumferentially arranged at the top of the inner ring silicone pressing plate 212. A plurality of through holes 20721 for the second fixing posts 2121 to pass through are circumferentially arranged on the fixed inner ring 2072. A plurality of second fixing holes 2112 that cooperate with the second fixing posts 2121 are circumferentially arranged at the bottom of the filling sealing disc 211. The inner ring silicone pressing plate 212 is firmly fixed to the bottom of the filling sealing disc 211 through the cooperation of the second fixing posts 2121 and the second fixing holes 2112, and at the same time presses the fixed inner ring 2072, ensuring a tight connection between the soft rubber seal 207 and the weighing substrate 204, and the installation and disassembly are convenient, simplifying the installation process and improving the assembly efficiency.

[0037] In one embodiment, the cross-sectional shape of the deformation groove 2073 is a U-shaped structure. This setting of the deformation groove 2073 allows the soft rubber seal 207 to have a certain deformation space when subjected to pressure, so as to better adapt to the small displacements and weighing during the filling process, maintaining the sealing effect while also increasing the durability and lifespan of the seal.

[0038] Please refer to Figures 1 to 3In one embodiment, the lifting assembly 202 includes a power source 2021, a guide assembly 2022 and two guide shafts 2023. The power source 2021 is fixed on the weighing base plate 204. The driving end of the power source 2021 is connected to the guide assembly 2022 and drives the guide assembly 2022 to rise and fall. The tops of the two guide shafts 2023 are respectively fixed at the two ends of the guide assembly 2022, and the bottoms thereof are respectively fixed at the two ends of the moving assembly 203. At the same time, the weighing base plate 204, the fixed inner ring 2072 of the soft rubber seal 207, the filling sealing disk 211 and the two ends of the inner ring silicone pressure plate 212 are respectively sleeved on the two guide shafts 2023, which can further strengthen the stability of the movement of the guide shafts 2023. In this embodiment, the power source 2021 is driven by an electric cylinder, and a mechanism that can provide power, such as a cylinder, can also be used. Driven by the electric cylinder, the guide assembly 2022 moves upward, further driving the guide shaft 2023 and the moving assembly 203 with or on which the container is placed to move upward, until the opening of the container hits the filling sealing disk 211, and the filling sealing disk 211 seals the opening of the container.

[0039] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0040] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings.
