[0001] The present invention relates to the technical field of filling, and in particular to a quantitative filling device for lubricating oil production and processing. Background Art

[0002] Lubricating oil filling refers to the process of injecting lubricating oil into containers. This process requires a series of preparatory and operating steps. Before filling lubricating oil, operators need to prepare filling equipment, including filling machines, metering tanks and other equipment, and ensure the stability of the electrical and gas sources of these equipment, ensure that all equipment and accessories work properly, ensure that the quality of lubricating oil and packaging materials meets the requirements, filter the lubricating oil and heat the lubricating oil to ensure that the lubricating oil meets the filling requirements.

[0003] There are various types of lubricating oil filling machines, among which the fully automatic lubricating oil filling machine is widely used in industries such as medicine, food, and daily chemicals. It uses piston metering, integrates mechanical and electrical, and pneumatic functions, and has the characteristics of stable and reliable performance, high filling accuracy, and strong adaptability. According to different filling outputs, multi-head filling nozzles can be designed to meet the needs of liquids with different viscosities and various containers.

[0010] Preferably, an oil discharge check valve with a one-way downward direction is provided on the second partition plate.

[0011] Preferably, the upper side of the air extraction control plug is wider than the lower side thereof. The air extraction control plug is suspended at the end of the air extraction pipeline. When the air extraction control plug moves upward, the air extraction pipeline is opened.

[0013] The beneficial effects of the present invention are as follows: The filling height adjustment system is installed on the filling bracket, and the filling lifting system is installed on the lower side of the filling height adjustment system. The filling height adjustment system adjusts the height of the filling lifting system according to the height of the container. Each filling system is installed on the filling lifting system, and then drives each filling system to descend during filling.

[0014] Each filling system includes a filling pipe, a filling opening and closing device, a pressurized air extraction device, and a flexible sealing device.

The air extraction pipeline is communicated with the air extraction power chamber above the pressurized air extraction piston. When the filling opening and closing device descends, it drives the air extraction control plug to descend until it abuts against the deflation reference plug column to open the air extraction pipeline. When the pressurized air extraction piston is pressed down by the filling opening and closing device, the negative pressure in the area of the air extraction power chamber between the pressurized air extraction piston and the first partition plate gradually increases. When the filling opening and closing device descends to the lower limit position, the deflation reference plug column blocks the air extraction control plug, thereby realizing the opening of the air extraction pipeline. Under the action of the negative pressure, the excess lubricating oil is sucked into the air extraction power chamber below the pressurized air extraction piston. When the filling opening and closing device rises, the air extraction pipeline is closed under the action of the gravity of the air extraction control plug to prevent the excess oil from dripping.
