Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil filling equipment, specifically an automated lubricating oil mixing and filling integrated machine. Background Technology

[0002] With the development of industrialization, the demand for lubricating oil is increasing. In the production process of lubricating oil, base oil and additives need to be mixed in proportion before it can be bottled. Currently, the proportioning of base oil and additives is usually done manually by weighing, which is very cumbersome.

[0003] A search revealed a Chinese patent with publication number CN217248270U that discloses a proportioning device for lubricating oil production. The device includes a proportioning tank, a motor fixedly connected to the bottom of the tank, and a rotating shaft mounted on the motor rotatably inside the tank. A stirring rod is fixedly connected to the rotating shaft inside the tank. A discharge pipe is connected through the lower right side of the tank. A controller and a support column are fixedly connected to the top of the tank, and a positioning plate is fixedly connected above the support column.

This requires the staff to open the cover plate on the top of the storage cylinder to add raw materials into the storage cylinder, which is very cumbersome to operate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a cylinder to drive a moving plate downwards, thereby pushing the raw material in the metering tank into the mixing tank. The cylinder also drives two moving plates upwards, creating a negative pressure inside the metering tank, which draws the raw material from the storage tank into the metering tank. This eliminates the need for manual addition of raw materials to the metering tank. The design of the movable rod shortens the travel distance of the bottom moving plate, allowing the raw materials that can be drawn into the two metering tanks to be different. This enables the two metering tanks to draw in the appropriate amount of raw materials according to the ratio of lubricating oil. The design of the adjusting rod allows for adjustment of the length of the movable rod to accommodate changes in the lubricating oil ratio.

[0017] 2. This utility model, through the design of the first and second blocking blocks, allows the second blocking block to move upward due to the negative pressure inside the metering tank when the moving plate moves upward, thus allowing the raw material in the inlet pipe to flow smoothly into the metering tank. During this process, the first blocking block will be tightly fitted with the first fixing ring to prevent the raw material or air in the mixing tank from being drawn into the metering tank. When the moving plate moves downward, the first blocking block will move downward under the action of water pressure, thus allowing the raw material to flow smoothly into the mixing tank through the conduit. At the same time, the second blocking block will be tightly fitted with the second fixing ring to prevent the raw material in the metering tank from flowing back into the inlet pipe.

[0025] 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.

[0026] Example: Figure 1-5As shown, this utility model provides an automated lubricating oil mixing and filling machine, including a mixing tank 1. The top two ends of the mixing tank 1 are respectively connected to conduits 2. The top of the conduits 2 is connected to a metering tank 3. A cylinder 4 is fixedly connected between the two metering tanks 3. A connecting rod 5 is fixedly connected to the output end of the cylinder 4. A first sliding rod 6 is fixedly connected to one end of the connecting rod 5, and a second sliding rod 7 is fixedly connected to the other end of the connecting rod 5. A movable rod 8 is slidably connected to the bottom of the second sliding rod 7. Movable plates 9 are provided at the bottom of both the first sliding rod 6 and the movable rod 8. A top cover 10 is provided on the top of the metering tank 3. The first sliding rod 6 and the second sliding rod 7 are both slidably connected to the top cover 10. An inlet pipe 1 is connected to the bottom of the metering tank 3 at a position adjacent to the conduits 2. 1; A first support frame 12 is fixed to one end of the inner wall of the conduit 2. A first spring 13 is fixedly connected to the bottom of the first support frame 12. A first block 14 is fixedly connected to the bottom of the first spring 13. A first fixing ring 15 is fixedly connected to the inner wall of the conduit 2 above the first block 14. The top of the first block 14 and the bottom of the first fixing ring 15 are movably connected. A second support frame 17 is fixedly connected to one end of the inner wall of the inlet pipe 11. A second spring 18 is fixedly connected to the top of the second support frame 17. A second block 19 is fixedly connected to the top of the second spring 18. A second fixing ring 20 is fixedly connected to the inner wall of the inlet pipe 11 below the second block 19. The bottom of the second block 19 and the top of the second fixing ring 20 are movably connected.

[0027] In this embodiment, before the lubricating oil is filled, the base oil and additives need to be mixed in a specific ratio. First, the cylinder 4 is opened, driving the connecting rod 5 upwards, which in turn moves the first slide rod 6 and the second slide rod 7 upwards. When the first slide rod 6 moves upwards, it moves the moving plate 9 at its bottom upwards, creating a negative pressure in the metering tank 3 at one end of the first slide rod 6. This draws the raw material from the inlet pipe 11 into the metering tank 3. During this process, the second block 19 moves upwards under the negative pressure, and the second spring 18 extends, allowing the raw material in the inlet pipe 11 to flow into the metering tank 3 through the gap between the second block 19 and the second fixing ring 20. This process is repeated as the cylinder 4 drives the first slide rod 6 upwards. The second slide bar 7 will also move upward synchronously. During this process, the movable rod 8 will gradually extend from inside the second slide bar 7. When the movable rod 8 is fully extended, it will drive the moving plate 9 at its bottom to move upward, thereby extracting the raw material in the other liquid storage tank 27. Through the design of the movable rod 8, the travel distance of the moving plate 9 at its bottom can be shortened, so that the raw materials that can be extracted into the two metering tanks 3 are different, so that the two metering tanks 3 can quantitatively extract the corresponding raw materials according to the ratio of lubricating oil raw materials. When the moving plate 9 stops moving, the negative pressure in the metering tank 3 disappears. At this time, the second block 19 will re-attach to the second fixed ring 20 under the pulling force of the second spring 18, thereby preventing the raw materials in the metering tank 3 from flowing back into the liquid inlet pipe 11.

[0028] When the two metering tanks 3 are filled with the corresponding proportions of raw materials, the cylinder 4 drives the connecting rod 5 to move downwards, thereby causing the first sliding rod 6 and the second sliding rod 7 to move downwards. When the first sliding rod 6 moves downwards, the moving plate 9 at its bottom also moves downwards. At this time, the pressure at the bottom of the moving plate 9 increases, thereby pushing the first block 14 downwards. At this time, the first spring 13 will extend, and the raw materials in the metering tank 3 will flow into the conduit 2 through the gap between the first block 14 and the first fixing ring 15, and then into the mixing tank 1 through the conduit 2. At the same time, the second block 19 will tightly connect with the second fixing ring 15. The rings 20 are fitted together to prevent the raw material in the metering tank 3 from flowing back into the inlet pipe 11. As the second slide bar 7 moves downward, the movable rod 8 will gradually retract into the second slide bar 7. When the movable rod 8 is completely retracted into the second slide bar 7, the second slide bar 7 will drive the moving plate 9 at the bottom of the movable plate to move downward, thereby pushing the raw material in the metering tank 3 at one end of the second slide bar 7 into the mixing tank 1. In this way, the two metering tanks 3 can deliver raw materials to the mixing tank 1 according to the ratio of lubricating oil. The cylinder 4 drives the two moving plates 9 to move downward multiple times, thereby adding raw materials to the mixing tank 1 multiple times.

[0029] The bottom of the first support frame 12 is fixedly connected to the first telescopic rod 16 inside the first spring 13, and the first telescopic rod 16 is fixedly connected to the first block 14; the top of the second support frame 17 is fixedly connected to the second telescopic rod 21 inside the second spring 18, and the second telescopic rod 21 is fixedly connected to the second block 19, and the top of the second block 19 is fixedly connected to the connecting ring 22.

[0030] In this embodiment, the first telescopic rod 16 and the second telescopic rod 21 can guide the first spring 13 and the second spring 18 respectively, so as to prevent the first spring 13 and the second spring 18 from twisting and deforming when they contract.

[0031] The second slide rod 7 has a cavity 23 inside. The top of the movable rod 8 extends into the cavity 23 and is fixedly connected to a moving block 24. The moving block 24 is slidably connected to the cavity 23. The bottom of the side wall of the movable rod 8 is threaded with a fastening screw 35. The side wall of the adjusting rod 34 is provided with multiple limiting grooves 36. The fastening screw 35 is movably connected to the limiting grooves 36.

[0032] In this embodiment, the design of cavity 23 and moving block 24 allows the movable rod 8 to be smoothly slidably connected with the second slide rod 7. The design of adjusting rod 34 allows the movable rod 8 to adjust its length according to the lubricating oil ratio. The design of fastening screw 35 and limiting groove 36 can fix the position of adjusting rod 34.

[0033] One end of the movable plate 9 is provided with an exhaust hole, and a sealing plug 25 is provided inside the exhaust hole. One end of the metering tank 3 is provided with an observation window 26. Both ends of the mixing tank 1 are provided with liquid storage tanks 27. One end of the liquid inlet pipe 11 is connected to the liquid storage tank 27. One end of the top of the liquid storage tank 27 is provided with a feeding port 28.

[0034] In this embodiment, the design of the vent hole allows the air at the bottom of the moving plate 9 to be smoothly discharged during the installation of the moving plate 9 into the metering tank 3. The design of the sealing plug 25 can block the vent hole of the installed moving plate 9, so that the moving plate 9 can smoothly generate negative pressure in the metering tank 3 when it moves upward. The design of the observation window 26 makes it convenient for the staff to observe the amount of raw materials in the metering tank 3.

[0035] A motor 29 is fixedly connected to the center of the top of the mixing tank 1. A stirring shaft 30 is connected to the output end of the motor 29. Three stirring blades 31 are fixedly connected to both ends of the stirring shaft 30. A discharge pipe 32 is connected to the bottom of the mixing tank 1. A solenoid valve 33 is installed at one end of the discharge pipe 32.

[0036] In this embodiment, when the mixing tank 1 contains a certain amount of raw materials, the motor 29 is turned on, and the stirring shaft 30 is driven to rotate by the motor 29, thereby driving the stirring blade 31 to rotate, so as to mix the two raw materials. After the raw materials are mixed, the solenoid valve 33 can be opened to allow the lubricating oil to be discharged from the discharge pipe 32.

[0037] Working principle: Before filling the lubricating oil, the base oil and additives need to be mixed in proportion. First, cylinder 4 is opened, driving connecting rod 5 upwards, which in turn moves the first sliding rod 6 and the second sliding rod 7 upwards. When the first sliding rod 6 moves upwards, it moves the moving plate 9 at its bottom upwards, creating a negative pressure in the metering tank 3 at one end of the first sliding rod 6. This draws the raw material from the inlet pipe 11 into the metering tank 3. During this process, the second plug 19 moves upwards under the negative pressure, and the second spring 18 and the second telescopic rod 21 extend. The raw material from the inlet pipe 11 flows into the metering tank 3 through the gap between the second plug 19 and the second fixing ring 20. Simultaneously, the first plug 14 fits tightly against the first fixing ring 15 under negative pressure, preventing air from entering the mixing tank 1. When the material is introduced into the metering tank 3, as the cylinder 4 drives the first slide rod 6 to move upward, the second slide rod 7 will also move upward synchronously. During this process, the movable rod 8 will gradually extend from the cavity 23 inside the second slide rod 7. When the movable rod 8 is fully extended, it will drive the bottom moving plate 9 to move upward, thereby extracting the raw material from the other storage tank 27. Through the design of the movable rod 8, the travel distance of the bottom moving plate 9 can be shortened, so that the raw materials that can be extracted into the two metering tanks 3 are different, so that the two metering tanks 3 can quantitatively extract the corresponding raw materials according to the ratio of lubricating oil raw materials. When the moving plate 9 stops moving, the negative pressure in the metering tank 3 disappears. At this time, the second block 19 will re-attach to the second fixed ring 20 under the pulling force of the second spring 18, thereby preventing the raw materials in the metering tank 3 from flowing back into the inlet pipe 11.

[0038] When the two metering tanks 3 are filled with the corresponding proportions of raw materials, the cylinder 4 drives the connecting rod 5 to move downwards, thereby causing the first sliding rod 6 and the second sliding rod 7 to move downwards. When the first sliding rod 6 moves downwards, the moving plate 9 at its bottom also moves downwards. At this time, the pressure at the bottom of the moving plate 9 increases, thereby pushing the first block 14 downwards. At this time, the first spring 13 and the first telescopic rod 16 will extend. Then, the raw materials in the metering tank 3 will flow into the conduit 2 through the gap between the first block 14 and the first fixed ring 15, and then into the mixing tank 1 through the conduit 2. At the same time, the second block 19 will fit tightly against the second fixed ring 20, thereby preventing the raw materials in the metering tank 3 from flowing back into the inlet pipe 11. During the downward movement of the second sliding rod 7, the movable rod 8 will gradually retract into the cavity 23 inside the second sliding rod 7. When the movable rod 8 is completely retracted into the cavity 23, the second sliding rod 7 will drive the bottom of the movable plate... The moving plate 9 moves downward, pushing the raw material in the metering tank 3 at one end of the second slide rod 7 into the mixing tank 1. In this way, the two metering tanks 3 can deliver raw materials into the mixing tank 1 according to the lubricating oil ratio. The cylinder 4 drives the two moving plates 9 to move downward multiple times, thereby adding raw materials into the mixing tank 1 multiple times. When the mixing tank 1 contains a certain amount of raw materials, the motor 29 is turned on, and the motor 29 drives the stirring shaft 30 to rotate, thereby driving the stirring blade 31 to rotate, so as to mix the two raw materials. After the raw materials are mixed, the solenoid valve 33 can be opened to allow the lubricating oil to be discharged from the discharge pipe 32. When the lubricating oil ratio changes, the length of the movable rod 8 needs to be adjusted. At this time, the operator needs to unscrew the fastening screw 35 on the movable rod 8, and then the adjusting rod 34 can be moved to adjust the length of the movable rod 8, so that the movable rod 8 can adjust its own length according to the lubricating oil ratio.

[0039] It should be noted that, to prevent the moving plate 9 from drawing air from the inlet pipe 11 into the metering tank 3 in the initial stage, the corresponding raw material can be pre-filled into the inlet pipe 11 during actual operation. When filling the inlet pipe 11 with raw material, the feeding port 28 on the storage tank 27 should be blocked first to prevent the raw material from flowing out through the other end (such as into the storage tank 27) and the feeding port 28 when adding material to the inlet pipe 11. When the feeding port is blocked, the top cover 10 of the metering tank 3 should be removed, along with the moving plate 9. Then, the operator can hook the connecting ring 22 at the top of the second blocking block 19 and pull it upwards. A gap will be created between the second block 19 and the second fixing ring 20. At this time, add the corresponding raw material into the metering tank 3 until the inlet pipe 11 is full of raw material and let the raw material flow into the metering tank 3, so that the bottom of the metering tank 3 is also filled with a certain amount of raw material. Then remove the sealing plug 25 of the moving plate 9 and install the moving plate 9 into the metering tank 3. At this time, the air at the bottom of the moving plate 9 will be discharged through the exhaust hole. When the bottom of the moving plate 9 contacts the raw material in the metering tank 3, the sealing plug 25 is installed on the exhaust hole of the moving plate 9. Finally, cover the metering tank 3 with the top cover 10. In this way, when the cylinder 4 drives the moving plate 9 to move upward, it will not draw air into the metering tank 3.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
