Description

Technical Field

[0001] This utility model relates to the field of quantitative filling technology, specifically to a quantitative filling device for solid-liquid mixtures. Background Technology

[0002] A filling machine is a type of packaging equipment primarily used for the mechanical filling of materials. Based on the material handling method, filling machines can be categorized into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. According to the level of automation, filling machines can also be divided into semi-automatic filling machines and fully automatic filling production lines. Filling machines use a series of mechanical devices to extract materials from storage tanks, transport them through pipelines to the filling position, and finally fill the materials into containers.

[0003] Current mainstream material filling machines are mainly used for filling pure materials, with limited applications for solid-liquid mixtures. A small number of material filling machines can handle small particles (less than 8mm in diameter) with low solid content and solid-liquid mixtures. However, for large particles (more than 8mm in diameter) with high solid content and solid-liquid mixtures, current technology uses solid-liquid separation for separate filling. This results in complex filling mechanisms, cumbersome procedures, difficulty in guaranteeing filling accuracy, slow production speed, and is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a quantitative filling device for solid-liquid mixtures, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a quantitative filling device for solid-liquid mixtures, comprising: a quantitative tube, a first filling valve installed on a cartridge hose at the outlet of a material cylinder, and a second filling valve connected to a filling head. The discharge end of the first filling valve is connected to the quantitative tube, and the discharge end of the quantitative tube is connected to the inlet end of the second filling valve. An air pressure regulating component is provided on the discharge end of the first filling valve.

[0006] Preferably, the air pressure regulating component includes a vent valve, which is installed at the discharge end of the first filling valve.

[0007] Preferably, the exhaust end of the vent valve is connected to a connecting pipe, one end of which is connected to the surface of the material cylinder, and the connecting pipe is in communication with the material cylinder.

[0008] Preferably, a vacuum valve is installed at the exhaust end of the vent valve, an exhaust pipe is installed at the exhaust end of the vacuum valve, and a vacuum tank is installed at one end of the exhaust pipe.

[0009] Preferably, a compressed air valve is installed at the exhaust end of the vent valve, one end of the compressed air valve is connected to an air inlet pipe, and one end of the air inlet pipe is connected to a compressed air tank.

[0010] Preferably, a stirring assembly is installed on the material cylinder;

[0011] The mixing assembly includes a mixing motor and a mixing blade. The mixing blade is installed inside the material tank, the mixing motor is installed on top of the material tank, and the mixing blade is installed at the output end of the mixing motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This quantitative filling device for solid-liquid mixtures consists of a first filling valve, a second filling valve, a vent valve, and a quantitative tube. Opening the first filling valve and the vent valve connects the quantitative tube to the material cylinder, allowing material to flow from the material cylinder into the quantitative tube. Once the quantitative tube is full, the first filling valve is closed, and the second filling valve is opened. The filling pressure forces the material in the quantitative tube into the filling container, completing the filling process. Repeating this filling process enables continuous production. The filling material ranges from pure liquids to large-particle solid-liquid mixtures, covering a wide range of materials. It can quantitatively fill different volumes of large-particle materials without requiring complex mechanical structures or high instrument costs.

[0014] 2. The quantitative filling device for this solid-liquid mixture is equipped with a vacuum valve, a vacuum tank, a compressed air valve, and a compressed air tank. By opening the vacuum valve and the vent valve, the pressure inside the quantitative tube is changed to negative pressure. By closing the vacuum valve and the vent valve, the first filling valve is opened, and the material flows into the quantitative tube from the material cylinder. After the quantitative tube is filled, the first filling valve is closed, and then the compressed air valve, the vent valve, and the second filling valve are opened. At this time, the compressed air forces the material in the quantitative tube into the filling container, completing the filling. Repeating this filling process can complete continuous production. For viscous materials containing particles, filling can also be completed by adding a vacuum valve, a vacuum tank, a compressed air valve, and a compressed air tank. Attached Figure Description
