Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid material filling, in particular to an automatic liquid material filling mechanism. Background Art
[0002] When filling liquid materials such as milk and beverages, the filling volume needs to be strictly controlled. Neither too little nor too much should be filled, which may cause overflow and waste.
[0003] In order to control the single filling volume, a metering pump can be used to pump and meter the liquid material during the filling process. However, the metering pump is far away from the packaging container and the filling rod, and a pipeline is required to connect the filling rod. The pipeline residue problem during the filling process is difficult to control, resulting in low filling accuracy. Moreover, after the packaging container is moved, the liquid material remaining in the filling rod is prone to dripping, causing pollution to the conveyor line, which needs to be improved.

[0017] The following combination Figures 1 to 3 The technical solution of the present utility model is further illustrated by specific embodiments.
[0018] like Figure 1 The automatic filling mechanism for liquid materials shown includes: a cantilever 5, a sleeve 1, a piston 2, a liquid inlet pipe joint 6, an air inlet pipe joint 7 and a filling rod 10. The sleeve 1 is vertically arranged on the cantilever 5 and extends downward. A U-shaped groove can be machined on the cantilever 5 to position the sleeve 1 and fixed with screws, so that the structure is stable.
[0019] The piston 2 is arranged in a liftable manner in the sleeve 1. In this embodiment, a cylinder 14 connected to the piston 2 is provided on the top of the sleeve 1. The piston 2 is lifted and lowered by the extension and retraction of the cylinder 14. The extension and retraction of the cylinder 14 can be controlled by a PLC to improve the level of automation.
[0020] A cover plate 3 is provided at the bottom of the sleeve 1. The cover plate 3 can be fixed to the bottom of the sleeve 1 by screws, which is convenient for assembly and disassembly. The bottom of the sleeve 1 is sealed by the cover plate 3. The liquid inlet pipe joint 6 is provided on the outer wall of the sleeve 1 and is located on the side of the descending path of the piston 2. The liquid inlet pipe joint 6 is connected to an external liquid pump to pump the liquid material into the space below the piston 2 in the sleeve 1. Figure 2 As shown, after the piston 2 moves downward, the liquid inlet pipe joint 6 is first sealed, and the feeding is automatically stopped.
[0021] An overflow safety valve 4 is provided on the outer wall of the sleeve 1 below the liquid inlet pipe joint 6. During the downward movement of the piston 2, the liquid material below is first pressed down, and the excess liquid material is discharged through the overflow safety valve 4. The overflow safety valve 4 is connected to the external material tank through the pipeline to recycle the liquid material.
[0022] The filling rod 13 is set at the bottom of the piston 2 and passes through the cover plate 3 downward. The top of the filling rod 13 and the bottom of the piston 2 can be fixed by screws and raised and lowered synchronously. A guide sleeve 11 is provided at the bottom of the cover plate 3, which is concentric with the filling rod and guides the lifting of the filling rod 13. Figure 2 As shown, the filling rod 13 is lowered and inserted into the mouth of the packaging container. In this embodiment, a first sealing ring 18 is provided in the guide sleeve 11 to prevent the liquid material from leaking downward from the inner wall of the guide sleeve 11.
[0023] like Figure 3 As shown, a valve sleeve 12 is located on top of the cover plate 3, concentric with the filling rod. The valve sleeve 12, guide sleeve 11, and cover plate 3 utilize an integrated stainless steel structure, offering high strength, wear resistance, and excellent corrosion resistance. A plurality of radially extending first valve holes 16 are arranged in an annular array at the bottom of the valve sleeve 12. The outer circumference of the filling rod is provided with a plurality of second valve holes 17, corresponding one-to-one with the first valve holes 16. The second valve holes 17 are slightly larger than the first valve holes 16, facilitating the passage of liquid material through the first valve holes 16 and into the second valve holes 17.
[0024] In this embodiment, the bottom of the filling rod 10 is concavely provided with a filling hole 13 extending upward to the second valve hole 17. Figure 2 and Figure 3 As shown, when the filling rod 10 descends with the piston 2 so that the first valve hole 16 is connected to the corresponding second valve hole 17, the piston 2 is located in front of the liquid inlet pipe joint 6 to block it, and the liquid material enters the second valve hole 17 through the first valve hole 16, and then enters the packaging container below through the filling hole 13 in the filling rod 10 for automatic filling.
[0025] The air inlet pipe joint 7 is arranged on the outer wall of the sleeve 1 and is located below the liquid inlet pipe joint 6. In this embodiment, the air inlet pipe joint 7 is externally connected to a nitrogen supply pipe 8, and a solenoid valve 9 is provided on the nitrogen supply pipe 8. The solenoid valve 9 can be controlled by a PLC. When the filling rod 10 descends with the piston 2 so that the first valve hole 16 is connected to the corresponding second valve hole 17, the solenoid valve 9 is opened, and nitrogen is input through the air inlet pipe joint 7 to accelerate the filling and clean the liquid material residue in the first valve hole 16, the second valve hole 17 and the filling hole 13 at the end of each filling. This can ensure the filling accuracy and avoid the problem of dripping from the filling hole 13 after the packaging container is moved.
[0026] like Figure 3 As shown, the filling rod 10 is provided with a second sealing ring 15 located above and below the second valve hole 17. Figure 1 As shown, after the filling rod 10 moves upward, it is sealed by the second sealing ring 15 to prevent the liquid material in the sleeve 1 from entering the second valve hole 17, further avoiding the problem of dripping.
