Description

Technical Field

[0001] This utility model relates to the technical field of food packaging machines, and in particular to a fully automatic liquid food packaging machine. Background Technology

[0002] Liquid food is a type of food that is in a liquid state and can dissolve into a liquid in the mouth. It is easier to swallow and digest than semi-liquid food and is non-irritating. After processing, liquid food needs to be packaged into bottles or bags using packaging equipment.

[0003] Chinese utility model patent CN221319292U discloses a quantitative filling device for liquid food. This device includes a holding tank covered with a cover plate. A quantitative frame is fixed to both sides of the bottom of the tank, and a filling tube is fixed to the bottom of each quantitative frame. Liquid guide tubes are fixed to both sides of the bottom of the tank. Control valves are fitted onto the surfaces of both the liquid guide tubes and the filling tubes. An anti-sedimentation mechanism is installed inside the tank. A quantitative adjustment mechanism is located at the top of each quantitative frame, and collection mechanisms are located on both sides of the bottom of the tank. This utility model not only improves the convenience of quantitative adjustment during filling and prevents sedimentation of the liquid food during use, thus improving the uniformity of the liquid food, but also avoids waste of the liquid food and prevents liquid food from sticking to the bottom of the filled bottle.

[0004] However, when the above-mentioned filling equipment is filling liquid food into packaging bottles or bags, its metering frame is independently sealed, which cannot efficiently expel the air in the metering process, resulting in a slow flow rate of liquid food and low work efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fully automatic liquid food packaging machine that allows for faster inflow and metering of liquid foods, resulting in higher work efficiency.

[0006] This utility model discloses a fully automatic liquid food packaging machine, comprising a storage tank, a motor, a stirring shaft, and stirring blades. The storage tank has an internal storage chamber. The motor is mounted on the storage tank via a frame. The stirring shaft is rotatably mounted in the storage chamber, and the motor's output shaft is drive-connected to the stirring shaft. Multiple stirring blades are mounted on the stirring shaft. The machine also includes a metering tube, a piston, a filling tube, and an opening / closing assembly. The metering tube is mounted on the lower end face of the storage tank, and its upper end communicates with the bottom of the storage chamber. The piston is mounted inside the metering tube, and the upper end of the filling tube is connected to the piston, passing through the piston and communicating with the inside of the metering tube. The opening / closing assembly is mounted at the bottom of the storage chamber and is used to intermittently open and close the upper end of the metering tube. A conveying mechanism for transporting packaging bags or bottles is located below the filling tube. The bag or bottle is conveyed to the output end of the filling tube, and the liquid food is conveyed and stored in the storage chamber of the storage tank. The motor drives the stirring shaft and multiple stirring blades to rotate, so that the multiple stirring blades stir the liquid food, making the liquid food more uniform. The opening and closing component opens the upper port of the metering tube, allowing the liquid food to enter and fill the space above the piston in the metering tube, realizing the metering of the liquid food. The opening and closing component closes the upper port of the metering tube, and the valve of the filling tube opens, allowing the liquid food in the metering tube to be added to the packaging bag or bottle through the filling tube, realizing the packaging of the liquid food. Compared with the existing technology, the metering tube is directly connected to the storage chamber of the storage tank. During metering, the air in the metering tube can be efficiently discharged, the liquid food flows in faster, and it is convenient for the liquid food to quickly fill the metering space of the metering tube, resulting in high work efficiency.

[0007] Preferably, the device also includes an air pipe connector, an air storage tank, and a solenoid valve.

The input end of the solenoid valve is connected to the inside of the air storage tank, and the output end of the solenoid valve is connected to the air pipe connector via a pipeline. The input end of the air storage tank is connected to a gas system via a pipeline. The gas system can be pure air, nitrogen, or other gases with preservation and anti-corrosion effects. When the valve of the filling tube is opened to deliver liquid food to the packaging bag or bottle, the solenoid valve opens, allowing the high-pressure air in the air storage tank to be input into the metering space of the metering tube through the pipeline and the air pipe connector, thereby quickly discharging the metered liquid food through the filling tube and improving filling and packaging efficiency.

[0008] Preferably, it also includes a detector, which is installed on the metering tube and has a probe that extends into the inside of the metering tube. The detector is used to detect whether the metering space in the metering tube is filled. The detector is a sensor such as a contact sensor, potential sensor, or pressure sensor that can detect whether there is liquid food in the metering tube. The detector is electrically connected to the solenoid valve and the valve of the filling tube. When the detector detects that the metering is complete, it sends an electrical signal to the valve of the filling tube and the solenoid valve. At this time, the solenoid valve and the valve of the filling tube can be opened for packaging and filling, improving the degree of automation and work efficiency.

[0009] Preferably, it also includes a threaded hole seat and a locking block. The threaded hole seat is installed on the lower end of the metering tube.

Using a wrench or other tools to clamp and move the locking block, the filling tube is rotated. The thread of the filling tube and the threaded hole seat interacts to raise and lower the tube, thereby adjusting the position of the piston inside the metering tube and adjusting the size of the metering space inside the metering tube above the piston to achieve different metering effects.

[0010] Preferably, the opening and closing assembly includes a swing arm and a gate. One end of the swing arm is connected to the stirring shaft, and the other end of the swing arm is equipped with the gate. The gate moves above the metering tube, and a sealing component is provided between the lower end face of the gate and the bottom of the storage chamber of the storage box. When the stirring shaft rotates, it drives the gate to rotate through the swing arm, so that the gate intermittently passes through the upper port of the metering tube. When the gate passes through the upper port of the metering tube, it closes the upper port of the metering tube. At this time, the metering tube is metered. When the gate moves out of the upper port of the metering tube, the liquid food flows into the interior of the metering tube to fill it. The structure is simple and practical.

[0011] Preferably, the opening and closing assembly includes a second gate, a lever, and a cam disc. The second gate is slidably installed at the bottom of the storage chamber of the storage box.

A cam slide is provided on the cam disc, and the cam slide of the cam disc is slidably connected to the lever. A sealing component is provided between the second gate and the bottom of the storage chamber of the storage box. When the stirring shaft rotates, it drives the cam disc to rotate.

The inner end of the swing rod is installed at the lower end of the stirring shaft. A sealing component is provided between the gate plate three and the bottom of the storage chamber of the storage box. When the stirring shaft rotates, it drives the swing rod to rotate. The swing rod drives the gate plate three to move back and forth through the pull rod and the vertical shaft, so that the gate plate three intermittently passes through the upper port of the metering tube. When the gate plate three passes through the upper port of the metering tube, it closes the upper port of the metering tube. At this time, the metering tube is metered. When the gate plate three moves out of the upper port of the metering tube, the liquid food flows into the metering tube to fill it. The structure is simple and practical.

When the indicator rod passes the detection end of the switch component, the switch component generates an electrical signal to adjust the angle relationship between the indicator rod and the opening and closing component, thereby detecting the angle of the stirring shaft and then detecting the opening and closing state of the upper port of the metering tube of the opening and closing component. When the switch component generates an electrical signal, the upper port of the metering tube is closed. At this time, the valve of the solenoid valve and the valve of the filling tube can be opened for material discharge, which has good practicality.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0018] like Figures 1 to 4 and Figure 7 As shown, a fully automatic liquid food packaging machine includes a storage tank 1, a motor 2, a stirring shaft 3, and stirring blades 4. The storage tank 1 has a storage chamber inside. The motor 2 is mounted on the storage tank 1 via a frame. The stirring shaft 3 is rotatably mounted in the storage chamber, and the output shaft of the motor 2 is connected to the stirring shaft 3. Multiple stirring blades 4 are mounted on the stirring shaft 3. The machine also includes a metering tube 5, a piston 6, a filling tube 7, and an opening / closing assembly. The metering tube 5 is mounted on the lower end face of the storage tank 1, and its upper end communicates with the bottom of the storage chamber. The piston 6 is mounted inside the metering tube 5. The upper end of the filling tube 7 is connected to the piston 6, and the filling tube 7 passes through the piston 6 and communicates with the inside of the metering tube 5. The opening / closing assembly is mounted at the bottom of the storage chamber of the storage tank 1. The device is used to intermittently open and close the upper port of the metering tube 5; it also includes an air pipe connector 8, an air tank 9, and a solenoid valve 10. The air pipe connector 8 is installed on the metering tube 5 and communicates with the inside of the metering tube 5. The air tank 9 is installed on the outside of the storage box 1 via a bracket. The input end of the solenoid valve 10 communicates with the inside of the air tank 9, and the output end of the solenoid valve 10 is connected to the air pipe connector 8 via a pipeline; it also includes a detector 13, which is installed on the metering tube 5 and has its probe extending into the inside of the metering tube 5; it also includes an indicator rod 23 and a switch component 24. The indicator rod 23 is installed on the upper end of the stirring shaft 3 and is located above the storage box 1. The switch component 24 is installed on the storage box 1 and is matched with the indicator rod 23.

[0019] A conveying mechanism for transporting packaging bags or bottles is installed below the filling tube 7. The packaging bags or bottles are transported to the output end of the filling tube 7, and the liquid food is transported and stored in the storage chamber of the storage tank 1. The motor 2 drives the stirring shaft 3 and multiple stirring blades 4 to rotate, causing the stirring blades 4 to stir the liquid food, making it more uniform. The opening and closing assembly opens the upper port of the metering tube 5, allowing the liquid food to enter and fill the space above the piston 6 in the metering tube 5, achieving metering of the liquid food. The opening and closing assembly closes the upper port of the metering tube 5, and the stirring shaft 3 drives the indicator rod. Rotation 23 aligns the indicator rod 23 with the detection end of the switch component 24. When the indicator rod 23 passes the detection end of the switch component 24, the switch component 24 generates an electrical signal, adjusting the angle between the indicator rod 23 and the opening / closing assembly. This detects the angle of the stirring shaft 3, and consequently detects the opening / closing state of the upper port of the metering tube 5. When the switch component 24 generates an electrical signal, the upper port of the metering tube 5 is closed, allowing the solenoid valve 10 and the valve of the filling tube 7 to open for material discharge. The detector 13 is used to detect whether the metering space of the metering tube 5 is fully filled. The detector 13 is a contact sensor, potential sensor, pressure sensor, etc., that can detect whether there is liquid food in the metering tube 5. The detector 13 is electrically connected to the solenoid valve 10 and the valve of the filling tube 7. When the detector 13 detects that the metering tube 5 has completed metering, the detector 13 sends an electrical signal to the valve of the filling tube 7 and the solenoid valve 10. At this time, the solenoid valve 10 and the valve of the filling tube 7 can be opened for packaging and filling. The input end of the gas storage tank 9 is connected to the gas system through a pipeline. The gas system can be pure air, nitrogen, or other gases with preservation and anti-corrosion effects. When the valve of the filling tube 7 is opened to deliver liquid food to the packaging bag or bottle, the solenoid valve 10 opens, allowing the high-pressure air in the air storage tank 9 to be input into the metering space of the metering tube 5 through the pipeline and air pipe connector 8. This allows the metered liquid food to be quickly added to the packaging bag or bottle through the filling tube 7, thus achieving the packaging of the liquid food. Compared with the existing technology where the metering tube 5 is directly connected to the storage chamber of the storage box 1, the air in the metering tube 5 can be efficiently discharged during metering, and the liquid food flows in faster, making it convenient for the liquid food to quickly fill the metering space of the metering tube 5, resulting in high work efficiency.

[0020] It also includes a threaded hole seat 11 and a locking block 12. The threaded hole seat 11 is installed on the lower end of the metering tube 5. A threaded hole is provided in the middle of the threaded hole seat 11, and a thread is provided on the outer wall of the filling tube 7. The thread of the filling tube 7 is rotatably threadedly connected to the threaded hole of the threaded hole seat 11. A locking block 12 is provided on the lower outer wall of the filling tube 7. By using a wrench or other tools to clamp and move the locking block 12, the filling tube 7 is driven to rotate. The thread of the filling tube 7 and the threaded hole seat 11 interact to raise and lower, thereby adjusting the position of the piston 6 inside the metering tube 5 and adjusting the size of the metering space inside the metering tube 5 above the piston 6 to achieve different metering effects. Example 2

[0021] like Figure 2 and Figure 3 As shown, based on Embodiment 1, the opening and closing assembly includes a swing arm 14 and a gate 15. One end of the swing arm 14 is connected to the stirring shaft 3, and the other end of the swing arm 14 is equipped with the gate 15. The gate 15 moves above the metering tube 5. A sealing component is provided between the lower end face of the gate 15 and the bottom of the storage chamber of the storage box 1. When the stirring shaft 3 rotates, it drives the gate 15 to rotate through the swing arm 14, so that the gate 15 intermittently passes through the upper port of the metering tube 5. When the gate 15 passes through the upper port of the metering tube 5, it closes the upper port of the metering tube 5. At this time, the metering tube 5 completes the metering. When the gate 15 moves out of the upper port of the metering tube 5, the liquid food flows into the interior of the metering tube 5 to fill it. The structure is simple and practical. Example 3

[0022] like Figure 5 As shown, based on Embodiment 1, the opening and closing assembly includes a second gate plate 16, a lever 17, and a cam disc 18. The second gate plate 16 is slidably installed at the bottom of the storage chamber of the storage tank 1.

The cam of the cam disk 18 slides through the lever 17 to drive the gate plate 16 to move back and forth along the radial direction of the storage box 1, so that the gate plate 16 intermittently passes through the upper port of the metering tube 5. When the gate plate 16 passes through the upper port of the metering tube 5, it closes the upper port of the metering tube 5. At this time, the metering tube 5 completes the metering. When the gate plate 16 moves out of the upper port of the metering tube 5, the liquid food flows into the interior of the metering tube 5 to fill it. The structure is simple and practical. Example 4

[0023] like Figure 6As shown, based on Embodiment 1, the opening and closing assembly includes a gate plate 19, a vertical shaft 20, a pull rod 21, and a swing rod 22. The gate plate 19 is slidably installed at the bottom of the storage chamber of the storage tank 1. The gate plate 19 moves radially along the storage tank 1 and passes through the upper port of the metering tube 5. The vertical shaft 20 is installed on the gate plate 19. One end of the pull rod 21 is rotatably connected to the vertical shaft 20, and the other end of the pull rod 21 is rotatably connected to the outer end of the swing rod 22. The inner end of the swing rod 22 is installed at the lower end of the stirring shaft 3. The gate plate 19 and the storage tank... A sealing component is installed between the bottom of the storage chamber 1. When the stirring shaft 3 rotates, it drives the swing rod 22 to rotate. The swing rod 22 drives the gate 3 19 to move back and forth through the pull rod 21 and the vertical shaft 20, so that the gate 3 19 intermittently passes through the upper port of the metering tube 5. When the gate 3 19 passes through the upper port of the metering tube 5, it closes the upper port of the metering tube 5. At this time, the metering tube 5 completes the metering. When the gate 3 19 moves out of the upper port of the metering tube 5, the liquid food flows into the interior of the metering tube 5 to fill it. The structure is simple and practical.

[0024] like Figures 1 to 7 As shown, this utility model discloses a fully automatic liquid food packaging machine. During operation, the conveying mechanism for packaging bags or bottles first transports them to the output end of the filling tube 7. The liquid food is then transported and stored in the storage chamber of the storage bin 1. Next, the motor 2 drives the stirring shaft 3 and multiple stirring blades 4 to rotate, causing the stirring blades 4 to stir the liquid food, making it more uniform. The position and quantity of the piston 6 inside the metering tube 5 are adjusted by rotating the filling tube 7 via the clamping block 12. Finally, the stirring shaft 3 drives the opening and closing assembly to open the upper port of the metering tube 5, allowing the liquid food to be dispensed. The liquid food is quantified by entering and filling the space above the piston 6 in the metering tube 5. The opening and closing assembly closes the upper port of the metering tube 5. After the detector 13 detects that the quantification inside the metering tube 5 is complete, the detector 13 sends an electrical signal to the valve of the filling tube 7 and the solenoid valve 10. At this time, the solenoid valve 10 and the valve of the filling tube 7 can be opened. Finally, the solenoid valve 10 opens so that the high-pressure air in the gas storage tank 9 is input into the metering space of the metering tube 5 through the pipeline and the gas pipe connector 8, thereby quickly adding the quantified liquid food into the packaging bag or bottle through the filling tube 7, thus realizing the packaging of the liquid food.

During metering, the air in the metering tube 5 can be discharged efficiently, and the liquid food flows in faster, which makes it convenient for the liquid food to quickly fill the metering space of the metering tube 5, resulting in high work efficiency. 2. By introducing high-pressure air from the gas storage tank 9 into the metering space of the metering tube 5 through the pipeline and gas pipe connector 8, a metered amount of liquid food is quickly discharged through the filling tube 7, thereby improving filling and packaging efficiency. 3. By adjusting the position of piston 6 inside the metering tube 5, the size of the metering space inside the metering tube 5 above piston 6 can be adjusted to achieve different metering effects; 4. It can detect the opening and closing status of the upper port of the quantitative tube 5 of the opening and closing component, thereby improving the accuracy of filling and packaging.
