[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a closed feeding device for lubricating oil preparation, such as... Figures 1-4 As shown, the closed feeding device for preparing lubricating oil includes a preparation box 1. An inlet groove is provided on one side of the upper surface of the preparation box 1. A sealing component is fixedly connected inside the inlet groove. A feeding box 2 is fixedly connected to the upper surface of the preparation box 1 outside the inlet groove. A suction component is fixedly installed on the upper surface of the feeding box 2.

[0026] The suction assembly includes a cylinder 3, the lower surface of which is fixedly mounted on the upper surface of the feeding box 2. A piston 4 is fixedly connected to the output end of the cylinder 3, and a sealing ring 5 is fixedly connected to the outer surface of the piston 4. Activating the cylinder 3 can drive the piston 4 to move upward. The sealing ring 5 can improve the sealing between the piston 4 and the inner wall of the feeding box 2, thereby effectively sucking the additives directly into the feeding box 2 through the feed pipe 11. Subsequently, the additives are released into the preparation box 1 as needed, realizing the closed-loop delivery and precise addition of the additives. This can effectively prevent external air from bringing in dust, particles, impurities, and other contaminants into the preparation box 1 during the open feeding process, thereby ensuring the cleanliness of the lubricant preparation environment and improving the purity and performance stability of the product.

[0027] The sealing assembly includes a sealing plate 6. The outer surface of the sealing plate 6 is fixedly connected to the inside of the inlet groove. A mounting bracket 7 is fixedly connected to the lower surface of the sealing plate 6. A through groove is formed in the middle of the upper surface of the mounting bracket 7. A push rod 8 is slidably connected inside the through groove. A sealing ball 9 is fixedly connected to the upper surface of the push rod 8. A spring 10 is fixedly connected to the lower surface of the sealing ball 9, located around the push rod 8. The inlet groove is formed in the middle of the upper surface of the sealing plate 6. The size of the inlet groove is adapted to the sealing ball 9. During the upward suction process of the piston 4, the sealing ball 9 seals the air. The entry groove on plate 6 is sealed to prevent air from being drawn into the preparation chamber 1 during the piston 4's suction process, which would prevent the material from being added through the feed pipe 11. During the piston 4's downward push, a pushing force is applied to the sealing ball 9 under pressure, causing the spring 10 to contract and the push rod 8 to move downward inside the through groove, so that the sealing ball 9 is away from the entry groove on the sealing plate 6. This allows additives and other materials to enter the preparation chamber 1 through the entry groove, thereby ensuring that the preparation chamber 1 remains sealed at all times, further preventing air from entering and thus ensuring the quality of the lubricating oil preparation.

[0028] A feed pipe 11 is fixedly connected to one side of the feeding box 2. A first valve 12 is fixedly installed on the upper surface of the feed pipe 11. The feed pipe 11 facilitates the addition of materials such as additives. The first valve 12 can close the feed pipe 11 after the additive enters the inside of the feeding box 2 to prevent the material from flowing out of the feed pipe 11 when the piston 4 is pushed down.

[0029] An observation window 13 is provided on the front surface of the feeding box 2, and a scale line 14 is provided on the front surface of the observation window 13. By observing the observation window 13 and the scale line 14, it is convenient to check the amount and status of the material inside the feeding box 2, so as to achieve accurate addition.

[0030] A fixing frame 15 is fixedly connected to the outer surface of the mounting frame 7. A filter screen 16 is fixedly connected inside the fixing frame 15. The fixing frame 15 facilitates the fixing of the filter screen 16. The filter screen 16 can filter the materials added to the preparation box 1, further ensuring the purity of the materials entering.

[0031] Working steps: First, starting cylinder 3 drives piston 4 to move upward. Sealing ring 5 improves the sealing between piston 4 and the inner wall of feeding box 2, so that additives can be directly sucked into the feeding box 2 through feeding pipe 11. Next, the first valve 12 is closed. The amount and status of material inside feeding box 2 can be easily viewed through observation window 13 and scale line 14. Second, starting cylinder 3 pushes piston 4 downward, applying a pushing force to sealing ball 9 under pressure, causing spring 10 to contract. Push rod 8 moves downward inside the through groove, so that sealing ball 9 is away from the inlet groove on sealing plate 6, allowing additives to enter the preparation box 1 through the inlet groove. Finally, filter screen 16 filters the material added into preparation box 1, further ensuring the purity of the material entering.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
