Description

Technical Field

[0001] This application relates to the field of beverage production equipment technology, specifically to a beverage filling anti-overflow structure. Background Technology

[0002] In the beverage production process, the filling stage plays a crucial role in product quality and production efficiency. Precise and stable filling operations ensure that the volume of each bottle of beverage meets regulations, while also preventing raw material waste and equipment contamination, thus providing essential support for large-scale beverage production. The overflow prevention and limiting structure, as a core auxiliary component in the filling process, is used to control the liquid filling volume and prevent overflow problems.

[0003] Existing piston-type filling head metering structures mostly rely on cylinders to control the piston stroke. The filling amount is controlled by adjusting the piston's movement distance. When the piston completes its forward movement according to the preset stroke, the amount of material discharged from the cavity reaches the set value. Then, the cylinder drives the piston to reset to terminate the filling. This type of structure achieves metering by controlling the piston stroke. The longer the stroke, the larger the filling volume. Different dosages can be achieved by adjusting the stroke length, and it also has an anti-overflow function.

[0004] However, in actual production, due to factors such as differences in beverage viscosity and fluctuations in filling flow rate, the liquid flow is prone to significant lag when processing high-viscosity beverages. Because of the strong intermolecular forces, these beverages respond slowly to changes in flow rate during the filling process. Often, even after reaching the preset liquid level, they will continue to flow along the inner wall of the filling head due to inertia. At this time, even if the piston reset action responds in time, the inertial flow of the liquid will still cause the liquid to continue filling after the piston stops moving, eventually overflowing the container. This not only wastes raw materials but also contaminates the equipment. Therefore, it is necessary to design a beverage filling anti-overflow structure. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a beverage filling anti-overflow structure, which solves the problem of overflow, waste of raw materials and pollution of equipment caused by the continuous flow of high-viscosity beverages along the inner wall of the filling head due to inertia during filling.

[0009] A drive assembly, mounted on the upper part of the filling head, is used to drive the sealing cover to slide axially on the filling head and to achieve the contact or separation between the large liquid passage and the sealing head. The drive assembly is adapted to create a negative pressure environment. The negative pressure is applied to the area where the sealing cover port is located by the liquid suction assembly mounted on the sealing cover, which is used to suck up the beverage attached to the area and temporarily store and recycle it.

One end of each sealing ring plate is equipped with multiple adapter rods, and the sealing cover is equipped with an adapter ring connected to the adapter rods.

[0013] Furthermore, the liquid suction assembly includes a transfer tube installed on the sealing cover, the sealing cover is provided with a flow guide surface, a plurality of liquid suction nozzles communicating with the transfer tube are installed on the flow guide surface, and a plurality of liquid suction tubes communicating with the negative pressure ring cover are connected to the transfer tube.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1 As shown, this application provides a beverage filling anti-overflow structure, including a filling gun 1. A detachable filling head 2 is installed at one end of the filling gun 1. The filling gun 1 is a piston-type filling head, which is the prior art. It realizes the extraction and pushing of beverage through the reciprocating motion of the piston, controls the amount of beverage entering the filling head 2, and is the power source of the entire filling process. Its piston stroke can indirectly affect the basic filling volume. A large liquid passage 21 is provided at the lower end of the filling head 2. The filling head 2 is used to transport the beverage pushed out by the filling gun 1. At the same time, the large liquid passage 21 is the drain hole of the filling head 2, which is used to transport the beverage into the container.

[0032] like Figures 1-3 As shown, a sealing component 3 is installed at the lower end of the filling head 2. The sealing component 3 controls the opening and closing of the beverage outflow channel through the driving part, which solves the problem of overflow due to inertia when filling high viscosity beverages, reduces raw material waste and equipment contamination. The sealing component 3 includes a sealing cover 31 that slides on the lower part of the filling head 2. The inner wall of the sealing cover 31 forms a sliding seal with the outer wall of the filling head 2, providing a stable mounting base for other components of the sealing component 3 and the liquid absorption part. At the same time, its internal space can constrain the flow of beverages to a certain extent, reducing splashing caused by liquid impact during the filling process.

[0033] A sealing plate 32 is fixedly installed at the lower end inside the sealing cover 31. The sealing plate 32 is made of food-grade stainless steel and is the direct load-bearing structure of the sealing part. It can withstand the pressure generated by the impact of high-viscosity beverages. A sealing head 33 adapted to the large liquid passage 21 is fixedly installed on the upper part of the sealing plate 32. The sealing head 33 is made of food-grade silicone. By tightly fitting or separating from the large liquid passage 21, the flow of beverages can be controlled. When it is necessary to stop filling, the sealing head 33 quickly fits into the large liquid passage 21 and directly blocks the flow of beverages, solving the problem of continuous flow of high-viscosity beverages due to inertia. When filling, the two separate, providing a channel for the flow of beverages.

[0034] The sealing plate 32 is provided with multiple small liquid passage holes 34. The diameter of the small liquid passage holes 34 is smaller than that of the large liquid passage holes 21. When the beverage flows out from the large liquid passage hole 21, it is dispersed into multiple fine streams through the small liquid passage holes 34 and enters the container. This can reduce the impact force of a single liquid stream, reduce splashing and bubble generation, and slow down the overall filling speed through dispersed flow. This allows time for the timely sealing of the sealing head 33 and reduces the risk of spillage.

[0035] like Figures 1-4 As shown, a drive assembly 4 is installed at the upper end of the filling head 2. The drive assembly 4 is used to provide power to enable the sealing assembly 3 to slide back and forth along the filling head 2, thereby controlling the opening and closing of the sealing head 33 and the large liquid passage 21. At the same time, it can form a negative pressure to provide power for the liquid absorption part to absorb the attached beverage. The drive assembly 4 includes an electric push rod 41 that is bolted to the upper part of the filling head 2. The electric push rod 41 serves as the power source of the drive assembly 4. When the power is turned on, its extension stroke and speed can be set by the controller. Its extension and retraction movement provides stable power for the sliding of the sealing assembly 3, ensuring that the sealing assembly 3 can complete the sealing action in time when the beverage reaches the preset liquid level.

[0036] A negative pressure ring 42 is fixedly installed on the filling head 2. The negative pressure ring 42 forms a negative pressure environment inside, providing continuous suction power for the liquid absorption part to absorb the attached beverage. It is the pressure source for realizing the liquid absorption function. A connecting plate 43 is bolted to the output end of the electric push rod 41. A connecting ring 44 that can slide along the axis of the filling head 2 is fixedly installed on the connecting plate 43. The connecting plate 43 transmits the linear motion of the electric push rod 41 to the connecting ring 44 to ensure the synchronization of the component movement. At the same time, the connecting ring 44 can slide stably along the axis of the filling head 2 to prevent the component from jamming due to deviation.

[0037] Multiple connecting rods 45 extending into the negative pressure ring cover 42 are fixedly installed at the lower part of the connecting ring 44. A sealing ring plate 46, capable of axially sliding inside the negative pressure ring cover 42, is fixedly installed at the lower end of each connecting rod 45. The connecting rods 45 synchronously transmit the movement of the connecting ring 44 to the sealing ring plate 46. Their number and distribution design ensure balanced force on the sealing ring plate 46, preventing tilting or sealing failure due to unilateral force. Simultaneously, the sealing ring plate 46 is made of rubber, and its outer circumference forms a sliding seal with the inner wall of the negative pressure ring cover 42. When the sealing ring plate 46 slides upward within the negative pressure ring cover 42 along with the connecting rods 45, the negative pressure... The internal space of the ring cover 42 expands and forms a negative pressure. This negative pressure provides suction for the liquid absorption part to absorb the beverage, ensuring that the attached liquid can be sucked in in time and temporarily stored in the negative pressure ring cover 42. Together with the action of the sealing component 3, it forms a double guarantee against overflow. When the sealing ring plate 46 is driven to slide downward in the negative pressure ring cover 42 by the connecting rod 45, the internal space of the negative pressure ring cover 42 shrinks and the air pressure increases, discharging the temporarily stored liquid to the outside of the negative pressure ring cover 42. At the same time, the downward movement of the sealing ring plate 46 drives the sealing cover 31 to move downward synchronously through the component, so that the sealing head 33 separates from the large liquid passage 21, providing a channel for beverage filling.

[0038] Multiple adapter rods 47 extending to the outside of the negative pressure ring cover 42 are fixedly installed at the lower part of the sealing ring plate 46, and an adapter ring 48 is fixedly installed at the upper part of the sealing cover 31. The lower ends of the adapter rods 47 are all fixedly connected to the adapter ring 48. The adapter rods 47 can make the adapter ring 48 and the sealing ring plate 46 move up and down synchronously, and further make the sealing cover 31 slide synchronously along the axial direction of the filling head 2 as the sealing ring plate 46 moves up and down. This drives the sealing plate 32 and the sealing head 33 to fit or separate from the large liquid passage 21, ensuring the control of the opening and closing of the beverage filling channel.

[0039] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a liquid suction component 5 is installed on the sealing cover 31. Under negative pressure, the liquid suction component 5 absorbs the attached beverage, realizing timely recovery of the attached liquid, preventing raw material waste and equipment contamination. The liquid suction component 5 includes a transfer pipe 51 fixedly installed at the lower end of the sealing cover 31. The transfer pipe 51 has an annular hollow structure and serves as a transfer channel for overflowing beverage. A guide surface 52 is provided at the lower end inside the sealing cover 31. Multiple suction nozzles 53 connected to the transfer pipe 51 are fixedly installed on the guide surface 52. The guide surface 52 is inclined, which can guide the beverage that is flowing inertia and attached to the surface of the guide surface 52 to the suction nozzles 53, reducing the liquid residue in the sealing cover 31 and reducing the overflow phenomenon during beverage filling. At the same time, under the suction of the negative pressure ring cover 42, the suction nozzles 53 can absorb the overflowing beverage guided by the guide surface 52, preventing the liquid from dripping onto the outside of the equipment or container and causing contamination.

[0040] Multiple suction tubes 54 are connected to the adapter tube 51, forming a delivery channel for overflowing liquid. The liquid sucked in by the suction nozzle 53 is collected by the adapter tube 51 and delivered to the negative pressure ring cover 42 for temporary storage. The upper end of the suction tube 54 passes through the adapter ring 48 and is connected to the negative pressure ring cover 42. Multiple limiting sleeves 55 are fixedly installed on the sealing cover 31 and sleeved on the suction tube 54. The limiting sleeves 55 guide the movement of the suction tube 54, preventing the suction tube 54 from getting tangled or displaced during the sliding of the sealing cover 31, and ensuring the unobstructed flow of the suction channel.

[0041] The negative pressure ring shroud 42 is connected to a drain pipe 49, which serves as a discharge channel for beverages temporarily stored inside the negative pressure ring shroud 42. One end of the drain pipe 49 is connected to the bottom of the negative pressure ring shroud 42, and the other end can be connected to a recycling device or a beverage delivery main pipeline to realize the secondary use of the recycled liquid. The second one-way valve 492 installed on the drain pipe 49 has a flow direction from the inside of the negative pressure ring shroud 42 to the outside. It can restrict the liquid to be discharged from the negative pressure ring shroud 42 through the drain pipe 49, preventing external air or liquid from flowing back in when the negative pressure ring shroud 42 forms a negative pressure, thus ensuring the stability of the negative pressure environment.

[0042] Each of the suction tubes 54 is equipped with a first one-way valve 491. One end of the suction tube 54 is connected to the adapter tube 51, and the other end passes through the adapter ring 48 and communicates with the inside of the negative pressure ring cover 42. The first one-way valve 491 installed at its end guides the flow from the suction tube 54 to the negative pressure ring cover 42. Only the beverage sucked in by the suction nozzle 53 is allowed to enter the negative pressure ring cover 42 for temporary storage through the adapter tube 51 and the suction tube 54, while preventing the liquid or gas in the negative pressure ring cover 42 from flowing back into the suction tube 54. This design can prevent the temporarily stored beverage from flowing back into the sealing cover 31 through the suction tube 54 when the sealing ring plate 46 moves down and the air pressure in the negative pressure ring cover 42 increases. This ensures the stability of the one-way suction function of the suction assembly 5 and avoids secondary contamination of the sealing area by the recovered liquid.

[0043] Working principle: When filling beverages, the electric push rod 41 drives the connecting plate 43 and the connecting ring 44 to move downwards. Through the connecting rod 45, the sealing ring plate 46 moves downwards inside the negative pressure ring cover 42. At this time, the internal space of the negative pressure ring cover 42 shrinks and the air pressure increases. The second one-way valve 492 opens and the first one-way valve 491 closes. The recovered liquid temporarily stored in the negative pressure ring cover 42 is discharged through the drain pipe 49. At the same time, the sealing ring plate 46 drives the sealing cover 31 to slide downwards along the filling head 2 through the adapter rod 47 and the adapter ring 48, so that the sealing head 33 separates from the large liquid passage 21. The beverage flows out from the large liquid passage 21, is dispersed through the small liquid passage 34 on the sealing plate 32, and is injected into the container.

[0044] When the beverage reaches the preset filling volume, the electric push rod 41 is driven in reverse, and the connecting plate 43 and the connecting ring 44 drive the connecting rod 45 and the sealing ring plate 46 to move upward. The sealing ring plate 46 moves upward within the negative pressure ring cover 42, expanding the internal space and creating negative pressure. At this time, the first one-way valve 491 opens and the second one-way valve 492 closes. Simultaneously, the sealing cover 31 moves upward with the sealing ring plate 46, and the sealing head 33 fits tightly with the large liquid passage 21, blocking the flow of beverage and preventing high-viscosity beverage from continuing to flow due to inertia. The negative pressure generated by the negative pressure ring cover 42 is transmitted to the suction nozzle 53 through the suction pipe 54 and the adapter pipe 51. Under the action of negative pressure, the beverage attached to the port area of ​​the sealing cover 31 is guided to the suction nozzle 53 through the guide surface 52, and then enters the negative pressure ring cover 42 for temporary storage through the adapter pipe 51 and the suction pipe 54, completing the recovery of the overflowing beverage and achieving double protection against overflow.
