[0034] The present application embodiment discloses a liquid packaging machine. Figure 1 and Figure 2A liquid packaging machine includes a packaging machine body 1, the packaging machine body 1 includes a barrel 11, and a stirring assembly 2 is arranged inside the barrel 11. The stirring assembly 2 includes a driving motor 21, and the top cover of the barrel 11 of the feeding mechanism is provided with an end cover 3. The driving motor 21 is fixedly connected to the end cover 3 away from the barrel 11. The axis of the output shaft of the driving motor 21 is located at the center of the end cover 3 and is perpendicular to the end cover 3. The output shaft of the driving motor 21 is connected with a flange coupling 211, and the flange coupling 211 is located above the end cover 3. The flange coupling 211 has a simple structure, is easy to disassemble and install, and is convenient for maintenance and replacement of the equipment. The end of the flange coupling 211 away from the driving motor 21 is coaxially connected with a first stirring shaft 22, and the first stirring shaft 22 passes through the end cover 3 and extends into the barrel 11. A stirring blade 221 is fixedly connected to the first stirring shaft 22 near the end cover 3. The stirring blade 221 stirs the liquid in the barrel 11 under the drive of the first stirring shaft 22. The first stirring shaft 22 is rotatably connected to the second stirring shaft 23 and the third stirring shaft 24 at the lower end of the stirring blade 221. The axes of the second stirring shaft 23 and the third stirring shaft 24 are located on the same straight line and perpendicular to the first stirring shaft 22. The second stirring shaft 23 and the third stirring shaft 24 are respectively located on both sides of the first stirring shaft 22. The ends of the second stirring shaft 23 and the third stirring shaft 24 that are away from each other are fixed with propellers 232. The shaft bodies of the second stirring shaft 23 and the third stirring shaft 24 are fixed with a plurality of first stirring rods 231 perpendicular to their own axes. The length of the first stirring rod 231 is less than the length of the blade of the propeller 232. Under the action of the water flow, the two propellers 232 respectively drive the second stirring shaft 23 and the third stirring shaft 24 to rotate around their own axes. At the same time, the first stirring shaft 22 drives the second stirring shaft 23 and the third stirring shaft 24 to rotate around the first stirring shaft 22, so as to fully stir the liquid in the barrel 11. The first stirring shaft 22 is rotatably connected to a support rod 26 near the bottom position. The support rod 26 is perpendicular to the first stirring shaft 22. Both ends of the support rod 26 are connected to the inner wall of the barrel 11. Two U-shaped brackets 261 are provided at the position of the barrel 11 corresponding to the support rod 26. The bracket 261 opens upward, and one end is fixed to the inner wall of the barrel 11 to form a slot along the length direction of the support rod 26. The bracket 261 can support the support rod 26 through the slot. The support rod 26 is detachably connected to the barrel 11 through the bracket 261, which is conducive to the cleaning of the entire stirring device. The first stirring shaft 22 corresponds to the support plate position, and two horizontal limit bosses 222 are fixed to the upper and lower sides of the support plate. The limit boss 222 can limit the support rod 26 in the middle of the two limit bosses 222. The support rod 26 can support the first stirring shaft 22 to be stable inside the barrel 11, and the driving motor 21 drives the first stirring shaft 22 to rotate, and the stirring blade 221 stirs the liquid, and at the same time drives the second stirring shaft 23 and the third stirring shaft 24 to rotate, so that the liquid can be stirred vertically and horizontally at the same time, making the stirring more sufficient and uniform.

[0035] Reference Figure 3 A circular connecting plate 25 is fixedly connected to the end of the first stirring shaft 22 near the bottom of the barrel 11, and a plurality of second stirring rods 251 are fixedly connected to the side of the connecting plate 25 away from the first stirring shaft 22. The second stirring rods 251 are evenly distributed along the circumference of the connecting plate 25. The second stirring rods 251 extend toward the bottom of the barrel 11, and the second stirring rods 251 are inclined from the connecting plate 25 to the inner wall of the bottom end of the barrel 11 away from the axis of the barrel 11. The second stirring rods 251 can stir the sediment at the bottom of the barrel 11, causing the sediment to float into the upper layer for full stirring, thereby making the stirring more uniform and reducing the generation of sediment.

[0036] Reference Figure 3 The end cover 3 is provided with a feed port 31, and a float valve 32 is fixedly connected to the feed port 31. The liquid to be packaged enters the barrel 11 through the feed port 31, and the float valve 32 can control the opening and closing of the feed port 31. When the liquid level is lower than the set value, the float drops, the valve opens, and the liquid is allowed to continue to flow in. When the liquid level reaches the set value, the float rises, the valve closes, and the liquid is stopped from entering, preventing the barrel 11 from overflowing due to excessive feeding. The end cover 3 is provided with two observation ports 33, and the positions of the observation ports 33 correspond vertically to the positions of the two brackets 261. When installing the first stirring shaft 22, on the one hand, the observation port 33 can be used to observe whether the support rod 26 is aligned with the opening position of the bracket 261, which is conducive to the installation of the first stirring shaft 22. On the other hand, during the operation of the equipment, the observation port 33 can be used to observe whether the equipment is operating normally. At the same time, when the equipment needs to be cleaned, water can be injected from the observation port 33 to clean the barrel 11. The two observation ports 33 are respectively provided with dust covers (not shown in the figure), which can prevent dust from falling into the interior of the barrel 11 .

[0037] The implementation principle of a liquid packaging machine in the embodiment of the present application is as follows: the pre-produced bag material is placed on the material placing rack, and the bag material passes through a plurality of transmission rollers and enters the longitudinal sealing component area of ​​the sealing mechanism for longitudinal sealing, and then enters the transverse sealing area for bottom sealing. The bag material is sealed in the sealing mechanism by heat sealing and formed into the shape of a bag. At the same time, the liquid to be packaged is placed inside the barrel 11, the drive motor 21 is started, the first stirring shaft 22, the second stirring shaft 23 and the third stirring shaft 24 rotate, and the stirring blade 221, the first stirring rod 231 and the second stirring rod 251 jointly stir the liquid inside the barrel 11. The fully stirred liquid enters the formed bag through the cooperation of the feeding pipe and the feeding valve. The filled bag is moved to the transverse sealing component area of ​​the sealing mechanism for sealing, and the bottom sealing operation of the next packaging bag is performed at the same time. After the hot pressing of the two sets of hot pressing plates of the transverse sealing component is completed, the slitter cuts the packaging bag, and the packaging bag is cut into individual packages. After all the liquids to be packaged are packaged, the stirring assembly 2 needs to be cleaned, the flange coupling 211 is disassembled to separate the drive motor 21 and the first stirring shaft 22, the end cover 3 is removed, and the first stirring shaft 22 is taken out from the end of the barrel 11. At this time, the support rod 26 leaves the bracket 261, and the first stirring rod 231 and the parts connected thereto are all taken out, and the stirring assembly 2 can be cleaned.
