Description

Technical Field

[0002] Liquid filling machines are mainly used for filling lotions, care solutions, oral solutions, disinfectants, eye wash solutions, nutrient solutions, alcoholic beverages, injection solutions, pesticides, medicines, perfumes, edible oils, lubricants and liquids in special industries.

[0003] For example, the authorization announcement number "CN210595223U" is named a high-precision liquid filling machine. Although this utility model realizes liquid filling through low-pressure drainage in a closed environment, it avoids the filling error caused by traditional piston filling, which not only ensures the filling environment, but also facilitates accurate filling quantitative control, which is conducive to the high-precision liquid filling work. However, the base is installed at the entrance of the cover through a vertical lifting device. Long-term operation will cause the base and the cover to be loosely sealed, resulting in inaccurate filling accuracy: the filling tube is not inserted into the container during filling, and dripping will occur, wasting resources.

A receiving block 18 is provided on the upper surface of the liquid collecting block 17. A cylinder 19 is provided on the front surface of the second mounting block 3. A telescopic rod 20 is provided on the lower surface of the cylinder 19. The end of the telescopic rod 20 away from the cylinder 19 is connected to the receiving block 18. A plurality of infusion ports 21 are provided on the lower surface of the liquid collecting block 17. The plurality of infusion ports 21 are all connected to the hose 15. A conveying mechanism 22 is provided below the liquid collecting block 17. The conveying mechanism 22 is fixed on the front surface of the base 1. A plurality of containers 23 are provided on the upper surface of the conveying mechanism 22. The plurality of containers 23 correspond to the plurality of infusion ports 21 one by one. The plurality of infusion ports 21 can simultaneously infuse a plurality of containers 23 at one time. The height of the filling port 21 is higher than that of the storage tank 4. Due to the communicating vessel principle, when the fan 7 is turned off, the liquid in the U-shaped tube 13 will not be affected by the atmospheric pressure and will flow out from the filling port 21 again. The inner wall of the filling port 21 is provided with a first sealed baffle 24 and a second sealed baffle 25. The surface of the first sealed baffle 24 is provided with a first through hole 26. The surface of the second sealed baffle 25 is provided with a second through hole 27. A sealing device is provided between the first sealed baffle 24 and the second sealed baffle 25. The first through hole 26 is sealed and connected through the sealing device.

[0018] The sealing device includes a first anti-drip block 28, two limiting through holes 29 are provided on the surface of the first anti-drip block 28, two limiting rods 30 are provided between the first closed baffle 24 and the second closed baffle 25, the two limiting rods 30 pass through the two limiting through holes 29 respectively, and springs 31 are sleeved on the outside of the two limiting rods 30, the upper ends of the two springs 31 are connected to the lower surface of the first anti-drip block 28, and the lower ends of the two springs 31 are connected to the upper surface of the second closed baffle 25.

[0019] A second anti-drip block 32 is disposed at the lower end of the filling port 21, and a plurality of through holes are disposed on the surface of the second anti-drip block 32. The second anti-drip block 32 can divide a single stream of water into multiple streams of water, and when the filling is stopped, the liquid in the filling port 21 is not easy to flow out.

[0020] The surface of the conveying mechanism 22 is evenly provided with a plurality of grooves 33, and the plurality of grooves 33 are matched with the container 23. The container 23 is placed on the grooves 33 to be more stable and not easy to fall over.

[0021] A pressure gauge 34 is provided on the upper surface of the storage tank 4, so that the pressure inside the storage tank 4 can be observed in real time.

[0022] The outer contour of the storage tank 4 is a capsule shape, which can better withstand pressure.

[0023] Working principle: first, multiple containers 23 are placed on the conveying mechanism 22, and the multiple containers 23 are conveyed to the bottom of the filling port 21 through the belt of the conveying mechanism 22, and then the cylinder 19 is started, and the telescopic rod 20 moves downward, thereby driving the liquid collecting block 17 to move downward. When the multiple filling ports 21 are respectively inserted into the multiple containers 23, the cylinder 19 is closed; then the feed valve 9 and the pressure relief valve 11 are closed, the air intake valve 6 is opened, and the fan 7 is started. Due to the action of pressure, the liquid in the storage tank 4 passes through the U-shaped tube 13 and then enters the liquid collecting block 17 through the hose 15, and then enters the multiple filling ports 21; the provided closing device, under the action of pressure, moves the first anti-drip block 28 downward, compresses the spring 31, and the liquid first passes through the first through hole 26, then passes through the gap between the first anti-drip block 28 and the inner wall of the filling port 21, and finally is discharged into the container 23 through the second through hole 27, and the filling is completed. When recycling, first start the cylinder 19, and move the liquid collecting block 17 upward through the telescopic rod 20. When it moves to the filling port 21 and is completely separated from the container 23, close the cylinder 19, and at the same time, close the fan 7 and open the pressure relief valve 11. Due to the principle of communicating vessels, the air pressure at both ends is consistent, and one side of the filling port 21 is higher than one side of the storage tank 4, and the liquid will flow back. At this time, close the pressure relief valve 11, and the liquid recovery is completed. At the same time, the first anti-drip block 28 is pushed by the spring 31, so that the first anti-drip block 28 is firmly against the first closed baffle 24 to prevent dripping and save resources. The device is loaded through the conveying mechanism 22, and there will be no poor sealing, thereby ensuring the accuracy of the filling.
