[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a precise feeding device for preparing blended oil additives includes a blending device 1. The blending device 1 has an inlet 11 at its top and an outlet 12 on its side wall. A support frame 13 is fixedly connected to the surface of the blending device 1. A vertical plate 14 is rotatably connected to the middle of the support frame 13. A fixing plate 15 is fixedly connected to the top of the vertical plate 14. A metering cylinder 16 is rotatably connected to the middle of the fixing plate 15. A square plate 17 is fixedly connected to the top of the support frame 13. The metering cylinder 16 and the square plate 17 are correspondingly arranged. A cylinder 18 is fixedly connected to the inner wall of the support frame 13. A round rod 19 is fixedly connected to the output end of the cylinder 18. The end of the round rod 19 is rotatably connected to the vertical plate 14. During operation, the material to be added is first placed inside the metering cylinder 16, and then the material is measured using the scale lines on the metering cylinder 16. After measurement is completed, the cylinder is activated. 18 causes the cylinder 18 to drive the round rod 19 to push the upright plate 14 to rotate. When the upright plate 14 rotates, the fixed plate 15 will drive the metering cylinder 16 to rotate. When rotating, the bottom of the metering cylinder 16 will contact the square plate 17. Then, during the rotation, the metering cylinder 16 and the fixed plate 15 will rotate due to the force of the upright plate 14 and the square plate 17, thereby tilting the metering cylinder 16. When tilted, the top of the metering cylinder 16 will continuously move closer to the feed port 11, and finally pour the internal material into the feed port 11, thereby accurately dispensing the material. Then, the cylinder 18 can be controlled to restore the metering cylinder 16 and continue dispensing. By adding the metering cylinder 16, the metering line of the metering cylinder 16 can be used to accurately control the material. Then, the cylinder 18 can be used to tilt the metering cylinder 16 to speed up the dispensing of the material. Thus, through the cooperation of the metering cylinder 16 and the cylinder 18, the accurate dispensing of the material weight can be achieved.
[0026] like Figures 2 to 4 As shown, multiple damping spring dampers 2 are fixedly connected inside both the vertical plate 14 and the square plate 17; a buffer plate 21 is fixedly connected to the end of each damping spring damper 2; the buffer plate 21 and the measuring cylinder 16 are correspondingly arranged; during operation, when the cylinder 18 controls the measuring cylinder 16 to return to its original position, the measuring cylinder 16 will shake when the moving speed is relatively fast. At this time, it will continuously move closer to the square plate 17 and the vertical plate 14 for contact. When it contacts, it will collide with the buffer plate 21. After the buffer plate 21 is subjected to force, it will squeeze the damping spring damper 2 to compress it, thereby eliminating the force through compression. This reduces the impact between the measuring cylinder 16 and the buffer plate 21 when they come into contact. By adding damping spring dampers 2, the impact generated when the measuring cylinder 16 shakes can be weakened, and the force can be continuously reduced through the buffering of the damping spring damper 2 during compression. Thus, the impact force is gradually reduced after multiple impacts.
[0027] like Figures 1 to 2As shown, the top of the metering cylinder 16 is connected to a guide plate 3; the inner wall of the guide plate 3 is sloped; during operation, when material is added to the metering cylinder 16, some material will contact the guide plate 3, and then the material will slide through the inner wall of the guide plate 3 into the guide plate 3, thereby increasing the accuracy of material entering the metering cylinder 16; by adding the guide plate 3, the material can be guided to enter the metering cylinder 16 more quickly when added, thereby increasing the receiving area of the metering cylinder 16.
[0028] like Figure 5 As shown, a suction cup 4 is fixed to the surface of the buffer plate 21 on the square plate 17; multiple suction cups 4 are arranged on the buffer plate 21; during operation, as the measuring cylinder 16 continuously approaches the square plate 17, the suction cup 4 will first contact the measuring cylinder 16, and then adsorb it when the measuring cylinder 16 is hit multiple times, so that the measuring cylinder 16 can be quickly stabilized and its shaking can be reduced. At the same time, when the measuring cylinder 16 and the suction cup 4 are in contact, the suction cup 4 will also reduce the impact force of the measuring cylinder 16 by its own flexibility; by adding suction cups 4, the measuring cylinder 16 can be quickly stabilized when it shakes, and its own flexibility can assist the damping spring shock absorber 2 in eliminating the impact force of the measuring cylinder 16.
[0029] like Figures 2 to 3 As shown, a spring telescopic rod 5 is fixedly connected to the inner wall of the square plate 17; a collection box 51 is fixedly connected to the end of the spring telescopic rod 5; the collection box 51 and the support frame 13 are slidably connected; during operation, when liquid material is poured into the metering cylinder 16, if material overflows, it will move down along the metering cylinder 16 and finally drip into the collection box 51 through the fixed plate 15. At this time, the collection box 51 will collect these dripping materials. At the same time, when the vertical plate 14 rotates, it will contact the collection box 51, and when it contacts, it will push the collection box 51 to slide. When sliding, the spring telescopic rod 5 will be compressed to cooperate with the collection box 51 to slide. By adding the collection box 51, the material overflowing from the metering cylinder 16 can be collected. At the same time, when the vertical plate 14 rotates, the collection box 51 will move continuously due to the push of the vertical plate 14, thereby reducing the influence of the spring telescopic rod 5 on the vertical plate 14 when moving.
[0030] like Figure 2 As shown, a baffle 6 is fixedly connected to the top of the support frame 13; the baffle 6 and the upright plate 14 are correspondingly arranged; during operation, when the cylinder 18 uses the round rod 19 to drive the upright plate 14 to rotate and return to its original position, if the upright plate 14 is still rotating after rotating to its initial position, it will contact the baffle 6. At this time, the baffle 6 stops the upright plate 14 from rotating. Thus, when the upright plate 14 rotates, the baffle 6 restricts the upright plate 14, thereby increasing the accuracy of the return; by adding the baffle 6, when the round rod 19 drives the upright plate 14 to return to its original position, the baffle 6 will provide a prompt to the upright plate 14, reducing its range of movement after the reset.
[0031] Working principle: The material to be added is first placed into the metering cylinder 16, and then measured by the scale lines on the metering cylinder 16. After the measurement is completed, the cylinder 18 is activated, which drives the round rod 19 to push the vertical plate 14 to rotate. When the vertical plate 14 rotates, the fixed plate 15 will drive the metering cylinder 16 to rotate. During the rotation, the bottom of the metering cylinder 16 will contact the square plate 17. Then, due to the force of the vertical plate 14 and the square plate 17, the metering cylinder 16 will rotate, thus tilting the metering cylinder 16. When tilted, the top of the metering cylinder 16 will continuously move closer to the feed port 11, finally emptying the internal material. The material enters the feed inlet 11, allowing for precise metering and dispensing. The cylinder 18 can then be controlled to restore the metering cylinder 16 and continue dispensing. When the cylinder 18 restores the metering cylinder 16, it may sway at higher speeds, causing it to move closer to the square plate 17 and the vertical plate 14. Upon contact, it will collide with the buffer plate 21. The buffer plate 21, under pressure, will compress the damping spring shock absorber 2, thus eliminating the force and reducing the impact between the metering cylinder 16 and the buffer plate 21 upon contact. During material dispensing into the metering cylinder 16, some material... The suction cup 4 will contact the guide plate 3, and then slide into the guide plate 3 through its inner wall, thus increasing the accuracy of material entering the metering cylinder 16 during feeding. As the metering cylinder 16 approaches the square plate 17, the suction cup 4 will first contact the metering cylinder 16, and then adhere to it during repeated impacts, making the metering cylinder 16 quickly stable and reducing shaking. At the same time, when the metering cylinder 16 contacts the suction cup 4, the suction cup 4 will also use its own flexibility to reduce the impact force on the metering cylinder 16. When liquid material is poured into the metering cylinder 16, if any material overflows, it will move down along the metering cylinder 16 and finally pass through the fixed plate. When the plate 15 drips into the collection box 51, the collection box 51 collects the dripping material. Simultaneously, as the vertical plate 14 rotates, it comes into contact with the collection box 51, pushing it to slide. During this sliding, the spring extension rod 5 is compressed, thus cooperating with the collection box 51 to slide. When the cylinder 18 uses the round rod 19 to rotate the vertical plate 14 back to its original position, if the vertical plate 14 continues to rotate after reaching its initial position, it will come into contact with the baffle 6. At this time, the baffle 6 stops the vertical plate 14 from rotating. Thus, the baffle 6 restricts the rotation of the vertical plate 14, increasing the accuracy of the restoration.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
