Description

Technical Field

[0001] This utility model belongs to the field of food filling, and in particular relates to a filling machine. Background Technology

[0002] Currently, widely used automated liquid preparation equipment, such as coffee machines, soy milk makers, and milk dispensers, is mainly used for making standardized beverages. Its parameters, such as proportions, water volume, and water temperature settings, are relatively fixed, making it suitable for large-scale, batch operations. However, the situation is quite different when preparing nutritional solutions (i.e., formulated liquid foods) for patients in medical and nursing care settings such as hospitals or nursing homes. These nutritional solutions are usually personalized according to doctors' prescriptions. Each patient's nutritional formula differs in terms of powder type, dosage, water volume, and required water temperature, representing a highly customized "niche" liquid preparation need.

[0003] Current customized solution preparation processes are generally conducted manually. Staff must manually set the water temperature according to the prescription, heat it to the specified temperature, take the corresponding amount of water, add the powder in the correct proportions, mix thoroughly, and then package it into several bags for patient consumption. For example, one formula might require 65°C water and 2L of water, packaged into 5 bags; another formula might require 60°C water and 1L of water, packaged into 2 bags. Because the requirements for each batch are different, manual operation involves frequent parameter adjustments, weighing and adding water, mixing, and sealing. The overall workflow is cumbersome, inefficient, and susceptible to human error, leading to a high risk of mistakes.

[0004] Therefore, there is an urgent need for an intelligent device that can automatically complete steps such as adding water, heating, mixing and dispensing according to prescription parameters, so as to reduce the labor intensity of staff in the preparation room and improve the efficiency and accuracy of nutrient solution preparation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a food filling machine that reduces the burden of manual labor and improves the efficiency of dispensing.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A filling machine for customized liquid preparation includes a water storage tank, a mixing tank, and a filling assembly. The water storage tank is connected to the mixing tank via a first pipeline, and the mixing tank is connected to the filling assembly via a second pipeline. At least one of the water storage tank and the mixing tank is equipped with a heating device. The mixing tank is provided with a feeding port, and the filling assembly is equipped with a liftable filling head. The material added through the feeding port is mixed with the liquid entering the mixing tank and then transported to the filling head through the second pipeline.

[0007] Therefore, by setting up a liftable filling head, the filling head can be lowered and inserted into the filling bag during use. This can effectively prevent liquid from spilling due to external environmental influences during the filling process. At the same time, inserting the filling head into the filling bag can effectively prevent excessive air bubbles from forming under the action of gravity.

[0008] Furthermore, the filling assembly includes a lifting frame, a movable plate mounted on the lifting frame, and a driving device for driving the movable plate to move. The filling head is mounted on the movable plate, and a storage container is correspondingly provided below the filling head for the filling head to be inserted into its inner cavity.

[0009] Furthermore, a waste liquid tank is provided below the filling head for the filling head to move downwards and drain liquid. The storage container is installed between the filling head and the waste liquid tank by a detachable shelf, so that the shelf can be removed to provide a passage for the filling head to move.

[0010] Furthermore, the water storage tank and the waste liquid tank are connected by a drain pipe, and a second valve is installed on the drain pipe.

[0011] Furthermore, the lifting frame also includes a guide rod, on which the movable plate is mounted; both ends of the guide rod are provided with limit blocks; and at least one limit switch is provided along the travel trajectory of the movable plate. The guide rod ensures stable and reliable travel of the mounting plate, while the limit switches allow the movable plate to be locked in a specific position, facilitating the filling operation.

[0012] Furthermore, the filling assembly also includes a cable chain, one end of which is fixed to the moving plate, and the other end of which is fixed to the housing of the filling machine. The second pipeline passes through the inner cavity of the cable chain and communicates with the filling head. The cable chain design prevents the second pipeline from bending and blocking liquid discharge during the movement of the moving plate.

[0013] Furthermore, the water storage tank and the mixing tank are located at the same height, and the filling assembly is located below the water storage tank and the mixing tank. The water storage tank, the mixing tank, and the filling assembly are all installed in the movable cabinet-type housing of the filling machine.

[0014] Furthermore, the filling assembly is equipped with multiple filling heads, and each filling head is connected to a peristaltic pump on a second pipeline. Using peristaltic pumps allows for higher precision requirements and enables filling according to a set quantity. Simultaneously, the peristaltic pumps can isolate the contents from the material inside the pipeline, preventing secondary contamination.

[0015] Furthermore, the water storage tank and the mixing tank are located at the same height, and the filling assembly is located below the water storage tank and the mixing tank. The water storage tank, the mixing tank, and the filling assembly are all installed in a box on one side of the filling machine. A control screen is installed in the upper part of the other side of the filling machine, and the lower part of the other side is set as the lifting and lowering area of ​​the filling head.

[0016] In addition, the mixing tank includes a tank body and a stirring device installed on the tank body. The stirring device is a magnetic stirring device, which includes a rotator disposed in the inner cavity of the tank body and a drive unit disposed outside the tank body for driving the rotator to rotate.

[0017] This utility model of filling machine adopts a magnetic stirring structure, which avoids the cleaning dead corners and contamination risks caused by the traditional stirring shaft passing through the tank. Only the rotating part inside the tank needs to be cleaned. The structure is simpler, easier to disassemble and maintain, and effectively improves the hygiene performance and cleaning efficiency of the equipment. It is suitable for liquid food preparation scenarios with high hygiene requirements.

[0018] In addition, the drive unit includes a motor and a rotating plate mounted on the motor, with a magnet mounted on the rotating plate on the side near the rotor.

[0019] Furthermore, the magnets are mounted on both ends of the rotating plate.

[0020] In addition, the drive unit is mounted on the bottom of the tank via a mounting bracket.

[0021] This invention has the following advantages: The filling head can be lowered and inserted into the filling bag during use, effectively avoiding air bubbles or spillage caused by high-drop filling, thus improving filling accuracy and neatness. It is suitable for liquid food filling scenarios requiring precise dispensing. This structure simplifies manual bag insertion, reduces operational intensity, and helps improve filling efficiency and product quality. Attached Figure Description

[0024] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0025] like Figures 1 to 3 As shown, a filling machine of this utility model for customized liquid preparation includes a water storage tank 1, a mixing tank 2, and a filling assembly 3. The water storage tank 1 is connected to the mixing tank 2 via a first pipe 4, and the mixing tank 2 is connected to the filling assembly 3 via a second pipe 5. The water storage tank 1 and the mixing tank 2 are located at the same height, and the filling assembly 3 is located below the water storage tank 1 and the mixing tank 2. The water storage tank 1, the mixing tank 2, and the filling assembly 3 are all installed inside a movable cabinet-type housing 10 of the filling machine. The water storage tank 1, the mixing tank 2, and the filling assembly 3 are all installed inside the housing on one side of the filling machine; a control panel 101 is installed in the upper area of ​​the other side of the filling machine, and the lower area of ​​the other side is set as the lifting area for the filling head 33.

[0026] like Figures 1 to 3As shown, the filling assembly 3 includes a lifting frame 31, a drive device 32 for driving the lifting frame 31, and a filling head 33 mounted on the lifting frame 31. A second pipeline 5 communicates with the filling head 33. The lifting frame 31 includes a lead screw 34 and a moving plate 35. The lead screw 34 is mounted on the drive device 32, the moving plate 35 is mounted on the lead screw 34, and the filling head 33 is mounted on the moving plate 35. The lifting frame 31 also includes a guide rod 37, and the moving plate 35 is mounted on the guide rod 37. Limiting blocks 38 are provided at both ends of the guide rod 37. The drive device 32 is a stepper motor. The filling assembly 3 also includes a cable chain 39. One end of the cable chain 39 is fixed to the moving plate 35, and the other end of the cable chain 39 is fixed to the housing of the filling machine. The second pipeline 5 passes through the inner cavity of the cable chain 39 and communicates with the filling head 33. A liquid outlet 211 is provided at the bottom of the tank 21. The liquid outlet 211 is connected to the filling assembly 3 via a second pipe 5, and a first valve 51 is installed on the second pipe 5. Multiple filling heads 33 are installed on the filling assembly 3. Each filling head 33 is connected to a peristaltic pump 6 on the second pipe 5, with the peristaltic pump 6 positioned at the end of the second pipe 5 closest to the filling head 33. A waste liquid tank 7 is provided below the filling head 33 for downward movement and liquid drainage, facilitating the discharge of waste liquid from the filling head 33 into the waste liquid tank 7 during cleaning of the filling machine's interior. Specifically, a storage container 8 is correspondingly provided below the filling head 33 for insertion into its internal cavity.

[0027] Through the above structural design, the lead screw 34 rotates under the drive of the stepper motor, thereby driving the moving plate 35 to move up and down vertically, realizing the lifting function of the filling head 33. This allows the filling head 33 to be inserted into the filling bag before filling, effectively avoiding liquid splashing or air bubbles caused by mismatched filling heights, improving the cleanliness and stability of the filling process, and is suitable for liquid dispensing needs of different packaging bag sizes. The drag chain 39 effectively constrains and protects the second pipeline 5 during the lifting and lowering process of the moving plate 35, preventing bending, tangling, or pulling of the pipeline during movement, thus ensuring smooth liquid delivery and system stability. The peristaltic pump 6 enables quantitative delivery of the filling liquid, improving filling accuracy. Simultaneously, the peristaltic pump 6 achieves physical isolation between the liquid inside the pipe and the pump body during operation, preventing contamination and meeting the application scenarios with high requirements for liquid hygiene and safety, suitable for dispensing special foods such as nutrient solutions.

[0028] During the filling stage, the stirred liquid food flows out from the outlet 211 at the bottom of the tank 21 and is transported to the filling assembly 3 via the second pipeline 5. A first valve 51 is installed on the second pipeline 5 to control the opening and closing of the overall liquid flow. The first valve 51 is connected to a distributor 52, which can divide the second pipeline 5 into multiple groups of channels according to the number of filling heads 33. Each group of channels is connected to a corresponding filling head 33, and a peristaltic pump 6 is installed in each group of channels.

[0029] During operation, the control system sequentially opens the first valve 51 according to the set formula parameters, and then evenly guides the fluid to each group of channels through the distributor 52. The peristaltic pump 6 drives the material to the corresponding filling head 33 in a preset quantitative manner, realizing multi-channel synchronous or sequential filling operation. This structure enables precise control of the filling volume of each channel and reduces liquid residue, making it suitable for customized filling scenarios of small batches and multiple bags of nutrient solution.

[0030] like Figure 3 and Figure 4 As shown, in another preferred embodiment of this utility model, at least one limit switch 36 is provided on the travel trajectory of the moving plate 35. The limit switch 36 is used to limit the stopping of the moving plate 35 at different positions to adapt to the needs of different operating conditions. Specifically, before filling, the filling head 33 can be stopped directly above the filling bag opening for easy manual alignment or automatic identification; during filling operation, the moving plate 35 can be stopped under the control of the limit switch 36 at the position where the filling head 33 is inserted into the filling bag to achieve splash-free filling; during the internal cleaning operation of the filling machine, the filling head 33 can be lowered to a position close to the waste liquid tank 7 for easy waste liquid collection and discharge. By setting the limit switch 36, the filling head 33 can be accurately switched between multiple functional positions, improving the operational flexibility and automation level of the equipment.

[0031] like Figure 2 , Figure 5 and Figure 6 As shown, the mixing tank 2 includes a tank body 21 and a stirring device 22 mounted on the tank body 21. The first pipe 4 and the second pipe 5 are both connected to the inner cavity of the tank body 21. The stirring device 22 is a magnetic stirring device. The magnetic stirring device includes a rotor 24 disposed within the inner cavity of the tank body 21 and a drive unit 25 disposed outside the tank body 21 for driving the rotor 24 to rotate. The drive unit 25 is mounted on the bottom of the tank body 21 via a mounting bracket 26. The drive unit 25 includes a motor 251 and a rotating plate 252 mounted on the motor 251. A magnet 253 is mounted on the side of the rotating plate 252 near the rotor 24. The magnets 253 are mounted on both end faces of the rotating plate 252. Specifically, as shown... Figures 1 to 3 As shown, the mixing tank 2 is provided with a feeding port 23, and the feeding port 23 is provided with a cover 27. The filling assembly 3 is equipped with a liftable filling head 33. The material added through the feeding port 23 is mixed with the liquid entering the mixing tank 2 and then transported to the filling head 33 through the second pipeline 5.

[0032] like Figures 1 to 3As shown, the storage container 8 is installed between the filling head 33 and the waste liquid tank 7 via a detachable shelf 9, providing a clearance passage for the filling head 33 to move after the shelf 9 is removed. The water tank 1 and the waste liquid tank 7 are connected by a drain pipe 13, on which a second valve 14 is installed. The water tank 1 is equipped with a heating device, integrating heating and heat preservation functions. Heating is achieved by a resistance heating wire, and an external insulation layer is used to maintain a constant water temperature. When the water temperature needs to be lowered, cold water is added to the water tank 1. If the water tank 1 is full, some water can be drained from the water tank 1 by opening the second valve 14 before adding cold water to lower the temperature.

[0033] like Figure 2 As shown, in a preferred embodiment of this utility model, the food filling machine further includes a water purifier 11. The water purifier 11 is connected to an external tap water supply. When water needs to be added to the water storage tank 1, the external tap water is filtered through the water purifier 11 and then enters the water storage tank 1 through the third pipe 12. In another preferred embodiment of this utility model, an electric heating element is provided on the third pipe 12. The electric heating element is used to heat the flowing water to improve the heating efficiency of the water in the water storage tank 1 and shorten the overall heating time.

[0034] Based on the above structure, when the filling machine of this utility model is in use, the external tap water is filtered through the water purifier 11 and enters the water storage tank 1 through the third pipe 12. After being heated to the set temperature by the heating device, it flows into the mixing tank 2 through the first pipe 4. The user can add powder or other ingredients through the feeding port 23 on the mixing tank 2, and then close the cover 27 on the feeding port 23. The magnetic stirring device 22 starts to work, in which the motor 251 drives the rotating plate 252 to rotate. The magnet 253 on the rotating plate 252 and the rotating element 24 in the inner cavity of the tank 21 generate magnetic coupling, thereby driving the rotating element 24 to rotate synchronously, realizing the stirring and mixing of the liquid inside the tank 21. By adopting a magnetic stirring structure, this utility model eliminates the through connection between the traditional mechanical stirring shaft and the tank 21, avoids the problem of material adhering to the surface of the stirring shaft and being difficult to clean, and solves the hygiene hazards caused by the deterioration of residues in the traditional structure. This structure only requires cleaning the rotor 24 inside the tank 21, making the cleaning process simpler and significantly improving the hygiene performance and cleaning efficiency of the filling equipment. It is particularly suitable for liquid food preparation scenarios with high hygiene requirements.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
