The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0037] like Figures 1 to 10 As shown, the present invention is a lubricating oil additive mixing device, comprising: a frame 1, a mixing barrel 2 fixedly mounted on the frame 1, a barrel cover 4 fixedly mounted on the top of the mixing barrel 2, a feeding mechanism 7 for adding additives into the mixing barrel 2, and a mixing mechanism 8 for uniformly mixing the additives with the lubricating oil;

[0038] The frame 1 includes a plurality of support legs installed vertically, and the inner sides of the support legs are fixedly installed on the outer wall of the mixing barrel 2, and a controller 3 is also installed on the support legs; a material inspection port 9 is installed at a lower position on the side of the mixing barrel 2, and a small amount of lubricating oil can be taken out for testing and checking the mixing condition by opening the material reduction port; a flip cover 5 is installed on the hinge of the barrel cover 4, and the lubricating oil can be easily added to the mixing barrel 2 by opening the flip cover 5, and a handle 6 is fixedly installed on the flip cover 5.

[0039] The material discharge mechanism 7 comprises: a fixed cylinder 71 for guiding the additive into the mixing barrel 2, a connecting block 72 fixedly connected to the fixed cylinder 71, and a rotating frame 73 aligned with the connecting block 72; a material discharge assembly is installed in the fixed cylinder 71, and the fixed cylinder 71 is fixed and passes through the barrel cover 4, and the bottom edge of the rotating frame 73 is evenly provided with filtering holes, and the rotating frame 73 is located below the connecting block 72, and the connecting block 72 is elliptical, which can prevent the connecting block 72 from blocking the lubricating oil when the lubricating oil is added;

[0040] The material discharge assembly includes: a material discharge barrel 711 for containing additives, a fixing ring 712 fixedly mounted on the outer wall of the material discharge barrel 711, a support ring 713 supporting the fixing ring 712, a support spring 714 supporting the support ring 713, and a blocking ring 715 fixedly mounted on the inner wall of the fixed barrel 71; both ends of the support spring 714 are fixedly connected to the blocking ring 715 and the support ring 713, and the material discharge barrel 711 can pass through the support spring 714, the support ring 713 and the fixing ring 712 are slidably mounted on the inner wall of the fixed barrel 71, and the support ring 713 slidably contacts the outer wall of the material discharge barrel 711; a slide groove 716 is provided at the bottom of the side of the material discharge barrel 711, a sliding ring 717 is slidably mounted in the slide groove 716, and a discharge hole 718 is provided on the circumference of the bottom of the slide groove 716; a material guide groove is provided on the circumference of the bottom of the inner wall of the material discharge barrel 711, and the material guide groove is aligned with the discharge hole 718.

[0041] It should be added that the diameter of the rotating frame 73 is relatively large, so that the lubricating oil poured into the opening on the barrel cover 4 can be poured into the rotating frame 73 .

[0042] Furthermore, the bottom of the inner wall of the lower barrel 711 is an upwardly convex arc surface, which facilitates the liquid additive to be discharged from the lower barrel 711 through the guide groove and the discharge hole 718, so that the liquid additive can fully flow out of the lower barrel 711.

[0043] Furthermore, the inner diameter of the support ring 713 is larger than the outer diameter of the sliding ring 717, while the inner diameter of the blocking ring 715 is smaller than the outer diameter of the sliding ring 717, and the outer diameter of the sliding ring 717 is larger than the outer diameter of the discharge barrel 711, so that the sliding ring 717 can pass through the support ring 713, but will be limited by the blocking ring 715.

[0044] Insert the lower barrel 711 containing the liquid additive into the fixed barrel 71, slide the fixed ring 712 into the fixed barrel 71, and calibrate the lower barrel 711 so that the central axis of the lower barrel 711 and the fixed sleeve coincide with each other, so as to prevent the support ring 713 from obstructing the sliding ring 717 during the insertion of the fixed barrel 71. After the fixed ring 712 contacts the support ring 713, the fixed ring 712 presses the support ring 713 downward, and the support ring 713 compresses the support spring 714. When the sliding ring 717 contacts the blocking ring 715, the blocking ring 71 The sliding ring 717 is pushed to slide upward in the slide groove 716, so that the discharge port 10 is exposed. When the sliding ring 717 contacts the top of the slide groove 716, the lower barrel 711 stops descending, and the liquid additive is discharged from the lower barrel 711 through the guide groove and the discharge hole 718. When the additive in the lower barrel 711 decreases, the support spring 714 pushes the support plate to rise, and the sliding ring 717 gradually descends in the slide groove 716, so that the exposed part of the discharge hole 718 decreases. After the addition is completed, the sliding ring 717 seals the discharge hole 718.

[0045] The liquid additive enters the guide cavity of the connecting block 72 through the fixed cylinder 71, is discharged through the opening of the guide cavity and falls into the rotating frame 73. The centrifugal force during the rotation of the rotating frame 73 can make the liquid additive flow evenly to the inner wall edge of the rotating frame 73, and then evenly sprinkle the additive through the filter hole, so as to facilitate the mixing of the lubricating oil and the additive.

[0046] It should be added that when the lubricating oil is added into the mixing barrel 2, the lubricating oil is poured into the rotating frame 73. During the rotation of the rotating frame 73, the lubricating oil falls to the bottom of the mixing barrel 2 through the filter holes, so that the impurities in the lubricating oil are filtered.

[0047] The mixing mechanism 8 includes: a motor 81 fixedly mounted on the barrel cover 4, a rotating shaft 82 fixedly connected to the output shaft of the motor 81, the rotating shaft 82 rotates and passes through the barrel cover 4, a first support rod 83 evenly fixedly connected to the side of the rotating shaft 82, and a first stirring blade 84, a second stirring blade 85, and a third stirring blade 86 fixedly mounted on multiple first support rods 83; the first stirring blade 84, the second stirring blade 85, and the third stirring blade 86 are all spiral-shaped, and can flip the lubricating oil and additives in the vertical direction during rotation.

[0048] The lower end of the rotating shaft 82 is fixedly connected to a mounting plate 87, the bottom of the mounting plate 87 is fixedly connected to a center shaft 88, a spiral blade 89 is fixedly installed on the center shaft 88, the spiral blade 89 is in sliding contact with the inner wall of the discharge pipe 11, and the discharge pipe 11 is fixedly connected to the bottom of the mixing barrel 2, the discharge pipe 11 is fixedly connected to the discharge port 10, and a valve is installed on the discharge port 10; a one-way member 14 is fixedly installed at the bottom of the mounting plate 87, the one-way member 14 consists of a mounting ring 141 fixedly installed at the bottom of the mounting plate 87, a rotating ring 142 rotatably installed on the mounting ring 141, a fixed block 146 that limits the rotation direction of the rotating ring 142, and a fixed spring 145 that pushes the fixed block 146.

[0049] The second support rod 15 is evenly fixedly connected to the side of the rotating ring 142, and the second support rod 15 is fixedly connected to the second spiral plate 13. The second spiral plate 13 is fixedly connected to the first spiral plate 12; the second spiral plate 13 and the first spiral plate 12 are in sliding contact with the inner wall of the mixing barrel 2, and the second spiral plate 13 is conical.

[0050] It should be added that the top of the first spiral sheet 12 is higher than the bottom of the rotating frame 73 , so that the first spiral sheet 12 can scrape off the lubricating oil and additives spilled from the rotating frame 73 .

[0051] A fixing groove 143 is provided on the circumference of the inner wall of the rotating ring 142, a mounting groove 144 is provided on the mounting ring, and the cross-section of the fixing block 146 is triangular; the fixing block 146 is slidably installed in the mounting groove 144, and the two ends of the fixing spring 145 are fixedly connected to the inner wall of the mounting groove 144 and the bottom of the fixing block 146; one end of the fixing block 146 is inserted into the fixing groove 143.

[0052] During the stirring process, the output shaft of the motor 81 drives the rotating shaft 82 to rotate forward, so that the first stirring blade 84, the second stirring blade 85, and the third stirring blade 86 rotate and stir and mix the lubricating oil and the additive, and the first stirring blade 84, the second stirring blade 85, and the third stirring blade 86 are spiral-shaped, and while stirring the lubricating oil and the additive, the lubricating oil and the additive can be turned upward to improve the mixing efficiency; the mounting plate 87 drives the mounting ring 141 to rotate, and the edge of the fixed groove 143 contacts the inclined surface on the fixed block 146, so that the fixed block 146 is pushed into the mounting groove 144, and the mounting ring 141 cannot drive the rotating ring 142 to rotate.

[0053] When the output shaft of the motor 81 drives the rotating shaft 82 to reverse, the vertical surface on the fixed block 146 contacts the inner wall of the fixed groove 143. When the mounting ring 141 drives the mounting fixed block 146 to rotate, the fixed block 146 drives the rotating ring 142 to rotate, and the rotating ring 142 drives the second support rod 15 to rotate. The second support rod 15 drives the second spiral piece 13 to rotate, and the second spiral piece 13 drives the first spiral piece 12 to rotate. During the rotation process, the first spiral piece 12 and the second spiral piece 13 scrape the lubricating oil on the inner wall of the mixing barrel 2 and push the scraped lubricating oil downward to improve the cleaning effect.

[0054] It should be added that an anti-wear layer is wrapped on the outer edges of the first spiral blade 12 and the second spiral blade 13 , and the anti-wear layer is made of foam and has a smooth surface to prevent the first spiral blade 12 and the second spiral blade 13 from scraping the inner wall of the mixing barrel 2 .

[0055] It should be noted that the liquid level of the lubricating oil in the mixing barrel 2 is lower than the bottom height of the rotating frame 73 .

[0056] When additives need to be added, the lower barrel 711 containing the liquid additive is inserted into the fixed barrel 71. After the additives in the lower barrel 71 fully enter the fixed barrel 71, the sliding ring 712 seals the discharge hole 718, and then seals the opening on the fixed barrel 71. The lower barrel 711 can be cleaned and filled after being taken out, which can prevent the additives from spilling out during the process of adding the additives.

[0057] During the process of mixing the lubricating oil and the additive, it is necessary to continuously control the output shaft of the motor 81 to rotate forward and reverse. When the output shaft of the motor 81 rotates forward, the first stirring blade 84, the second stirring blade 85, and the third stirring blade 86 stir the lubricating oil and the additive and flip them upward. When the output shaft of the motor 81 rotates reversely, the first stirring blade 84, the second stirring blade 85, and the third stirring blade 86 stir the lubricating oil and the additive and flip them downward. The first spiral blade 12 scrapes the lubricating oil and additive on the inner wall of the mixing barrel 2 to avoid wasting the lubricating oil and additive splashing on the inner wall of the mixing barrel 2.
