Technical Field

[0001] This utility model relates to the technical field of lubricating oil filling equipment, specifically an automatic lubricating oil filling device that precisely controls the mixing ratio. Background Technology

[0002] Lubricating oil is generally formed by blending base oil and additives. It mainly plays a role in lubrication, auxiliary cooling, rust prevention, sealing and buffering. As an industrial equipment for automatic lubricating oil filling, automatic lubricating oil filling equipment is usually equipped with metering control valves to accurately control the proportion of multi-component lubricating oil, so as to achieve the mixing of lubricating oil according to the preset ratio.

[0003] In actual production, after the automatic lubricating oil filling device completes the filling, there is often residual lubricating oil at the filling port at the bottom of the filling head, which drips downwards under its own weight. This causes a large amount of lubricating oil to be contaminated on the conveying mechanism or the placement table below, which not only causes a certain degree of environmental pollution, but also wastes lubricating oil.

[0025] Please see Figure 1-4 As shown, this utility model is an automatic filling device for lubricating oil with precise control of mixing ratio, comprising:

[0026] A filling rack 11 is provided with a mixing component at its top. A fixing frame 16 is fixedly provided on one side of the filling rack 11. A metering pump 17 is fixedly provided at the top of the fixing frame 16. The inlet of the metering pump 17 is connected to an inlet pipe 18, and the outlet of the metering pump 17 is connected to a filling head 19.

[0027] The mixing unit includes several storage tanks 12 embedded at the top of the filling rack 11. The storage tanks 12 are used to store base oil and additives. The bottom of each storage tank 12 is connected to a conveying pipe 14, and the outer wall of each conveying pipe 14 is fixed with a metering control valve 13. The metering control valve 13 is used to accurately control the material feeding ratio in each storage tank 12. One end of several conveying pipes 14 is connected to a mixing box 15. The mixing box 15 is used to mix the lubricating oil. The bottom end of the liquid inlet pipe 18 passes through the top of the mixing box 15 to the inside of the mixing box 15. The metering pump 17 is used to accurately control the amount of lubricating oil being filled.

[0028] The scraping component includes a servo motor 21. A lead screw 22 is fixedly provided at the output end of the servo motor 21. A support frame 23 is threaded on the outer wall of the lead screw 22. A collection box 24 is fixedly provided at the bottom end of the support frame 23. A first scraper 25 is fixedly provided at the top inner end of the collection box 24. The top end of the first scraper 25 is located at the same horizontal plane as the bottom end of the filling head 19. A connecting hose 26 is connected to the bottom end of the collection box 24.

[0029] The servo motor 21 is used to provide the driving force required for the first scraper blade 25 to move and scrape the liquid. One end of the servo motor 21 is fixedly mounted on one side of the mounting bracket 16. The collection box 24 is used to collect the scraped lubricating oil. One end of the connecting hose 26 is connected to the top of the mixing tank 15.

[0030] The scraping component also includes a slide bar 27, the outer wall of which penetrates one side of the support frame 23, and one end of the slide bar 27 is fixedly connected to one side of the fixing frame 16.

[0031] The slide bar 27 is used to limit the movement of the support frame 23, so that it moves horizontally along the direction of the lead screw 22.

[0032] A second scraper 29 is fixedly provided at the inner bottom of the collection box 24;

[0033] The outer wall of the lead screw 22 penetrates one side of the fixed frame 16, and a limiting plate 28 is rotatably provided at one end of the lead screw 22. One side of the limiting plate 28 is fixedly connected to the other end of the slide rod 27.

[0034] The lead screw 22 is rotatably engaged with the fixed frame 16, and the limiting plate 28 is used to limit the position of the support frame 23 to prevent it from moving and separating from the lead screw 22.

[0035] Working principle: After the filling head 19 finishes filling, the servo motor 21 is turned on. The servo motor 21 drives the lead screw 22 to rotate. The rotation of the lead screw 22 drives the collection box 24 to move to the right through the support frame 23. The collection box 24 drives the first scraper 25 to move to the right. After the first scraper 25 contacts the bottom of the filling head 19, the first scraper 25 scrapes off the residual lubricating oil. The scraped lubricating oil drips down the first scraper 25 into the collection box 24 and is transported and recycled along the connecting hose 26. In this way, the residual lubricating oil at the bottom of the filling head 19 can be scraped off and recycled, which not only avoids the waste of residual oil, but also avoids environmental pollution.

[0036] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The filter component includes a filter plate 31. A lever 32 is rotatably provided on one side of the filter plate 31. An elastic block 33 is fixedly provided at the bottom end of one side of the lever 32. A frame 34 is engaged on the outer wall of the elastic block 33. One side of the frame 34 is fixedly provided on one side of the collection box 24.

[0038] The filter plate 31 is used to filter the scraped residual oil, and the card frame 34 has a card hole on one side that is adapted to the elastic block 33.

[0039] The filter component also includes two slide bars 35, with the opposite sides of the two slide bars 35 fixedly disposed on both sides of the filter plate 31, and the outer walls of the two slide bars 35 slidably connected to both sides of the inner wall of the collection box 24.

[0040] The slide bar 35 is used to assist in the installation of the filter plate 31. Both sides of the inner wall of the collection box 24 are provided with slide grooves that are compatible with the slide bar 35, and one end of the slide groove passes through one side of the collection box 24.

[0041] The bottom end of the filter plate 31 contacts the top end of the second scraper plate 29;

[0042] Working principle: When the lubricating oil scraped by the first scraper 25 passes through the filter plate 31, it can be filtered. When cleaning the filter plate 31, press the elastic block 33 inward and rotate the lever 32 upward until the lever 32 rotates upward to 180 degrees. Then pull the lever 32 outward. The lever 32 drives the filter plate 31 to move outward. Under the action of the second scraper 29, the lubricating oil at the bottom of the filter plate 31 is scraped until the filter plate 31 separates from the collection box 24. Through this movable assembly of the filter plate 31, not only can the scraped lubricating oil be filtered to improve the cleanliness of residual oil recovery, but it is also convenient to disassemble and clean the filter plate 31, thereby ensuring the filtration effect of the filter plate 31.
