[0017] Reference Figures 1 to 4 As shown, this utility model provides a quantitative feeding device for lubricating powder processing and production, including: a box body 1 and a mounting plate 8. The upper end of the inner cavity of the box body 1 is fixedly connected to a fixing frame 4. The inner cavity of the fixing frame 4 is evenly divided into multiple sets of transition grooves by a partition plate 2. The transmission column 17 is movably connected in the transition grooves through a sealed bearing. One end of the transmission column 17 is engaged with a worm gear assembly 20 through a worm wheel. The other end of the transmission column 17 is fixedly connected to a rotating cylinder 3 through a fixing plate 19. The surface of the rotating cylinder 3 is fixedly connected to a limiting plate 14 through a through-hole. At the same time, buffer grooves are symmetrically opened on the surface of the limiting plate 14. A guide rod 16 is fixedly connected in the buffer groove. Springs are sleeved at both ends of the guide rod 16. A buffer block 15 is slidably connected in the middle of the guide rod 16. The buffer block 15 is fixed. The outer side of the metering box 12 is connected, and the metering box 12 is slidably connected to the surface of the limiting plate 14 via the buffer block 15. The bottom of the inner cavity of the metering box 12 is screwed with an adjusting screw 10. The upper end of the adjusting screw 10 is movably connected to the adjusting plate 13 via a sealed bearing. The adjusting plate 13 is slidably connected to the inner cavity of the metering box 12 via the adjusting screw 10. The lower surface of the metering box 12 is fixedly connected to the vibrator 11. The mounting plate 8 is fixedly connected to the upper surface of the box 1 via the mounting ring 7. The upper surface of the mounting plate 8 is symmetrically connected to the storage box 9. The outer side of the metering box 12 is movably connected to the worm gear assembly 20 via a bearing. The outer side of the metering box 12 is fixedly connected to the servo motor 21. The servo motor 21 is fixedly connected to one end of the worm gear assembly 20 via a coupling.

[0018] In this embodiment, the capacity of the corresponding metering box 12 is first determined according to the ratio of each raw material in the lubricating powder. Then, the adjusting screw 10 is rotated. The adjusting screw 10, connected to the metering box 12, can push the adjusting plate 13 to move accordingly within the metering box 12, thereby achieving convenient adjustment of the capacity of the metering box 12. Moreover, the side of the metering box 12 has scale lines, which can help improve the convenience of capacity adjustment. After adjustment, the storage box 9 is fixedly connected to the upper surface of the box 1 by the mounting ring 7 and the mounting plate 8. The solenoid valve at the discharge port of each storage box 9 is opened, so that the raw material in the storage box 9 can fall into the corresponding transition groove. The vibrator 11 is turned on, and the vibrator 11 can drive the metering box 12 to vibrate, ensuring that the raw material can smoothly fill the inner cavity of the metering box 12, helping to improve the accuracy of the ratio between the raw materials. The guide rod 16, spring and buffer block are used to achieve this. The cooperation of 15 can help enhance the stability of vibration between the limit plate 14 and the metering box 12. Then, the switch of servo motor 21 is turned on. The output shaft of servo motor 21 drives the fixedly connected worm gear assembly 20 to rotate through the coupling. Each worm fixedly connected in the worm gear assembly 20 drives the transmission column 17, fixed plate 19, rotating cylinder 3, limit plate 14 and metering box 12 to rotate synchronously at low speed through the corresponding meshing worm wheel. After the rotating cylinder 3 rotates once, servo motor 21 is periodically turned off. When the opening of metering box 12 connects to the lower end of the inner cavity of box 1, the raw material in the inner cavity of metering box 12 can slide down quickly under the dual action of gravity and vibration, thereby improving the accuracy of the ratio between the raw materials of lubricating powder and improving the quality of the finished lubricating powder. The lubricating powder raw material mixed in the inner cavity of box 1 will also be discharged from the discharge port opened at the bottom of the inner cavity of box 1, which facilitates the subsequent processing of lubricating powder.

[0019] In a preferred embodiment, the fixed frame 4 has a square cylindrical structure. Three sets of partition plates 2 are fixedly connected at equal intervals along the length direction inside the fixed frame 4, and all three sets of partition plates 2 have a square structure. The fixed frame 4 and the partition plates 2 are combined to form a U-shaped structure, and the length of the partition plate 2 is equal to the height of the fixed frame 4.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The setting of the fixed frame 4 and the partition plate 2 allows the rotating cylinder 3, which is movably connected within the fixed frame 4, to be in relatively independent spaces, thereby avoiding the problem of accidental mixing of raw materials in different transition tanks.

[0021] In a preferred embodiment, the inner cavity of the fixed frame 4 is divided into four groups of transition grooves by the partition plate 2. The four groups of transition grooves are all square in structure, and the upper ends of both sides of the transition groove are symmetrically connected to two groups of guide plates 5. The end faces of the two groups of guide plates 5 are all triangular in structure, and the lower surface of the guide plate near the inclined surface of the rotating cylinder 3 is arc-shaped.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The arc surface of the lower surface of the guide plate 5 fits the outer side of the rotating cylinder 3, and the inclined structure of the upper surface of the guide plate 5 allows the lubricating powder material in the transition groove to slide directly into the metering box 12, thereby reducing the probability of the material remaining in the transition groove.

[0023] As a preferred embodiment, the rotating cylinder 3 has an overall cylindrical structure, the cross-section of the rotating cylinder 3 has a C-shaped structure, and the two sets of fixing plates 19 fixedly connected at both ends of the rotating cylinder 3 have a circular structure. At the same time, the diameter of the fixing plate 19 is equal to the outer diameter of the rotating cylinder 3, and the transmission column 17 at the end of the rotating cylinder 3 away from the worm gear assembly 20 has a cylindrical structure.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The setting of the fixing plate 19 can help enhance the overall structural strength of the rotating cylinder 3, and the opening of the rotating cylinder 3 allows the raw material in the transition groove to fall smoothly into the metering box 12, thereby helping to realize the metering of the metering box 12. At the same time, the hollow structure of the transmission column 17 facilitates the fixed connection of the plug interface through the cover plate. The plug interface is electrically connected to the battery fixedly connected inside the rotating cylinder 3, which facilitates the charging of the battery. The battery is also electrically connected to the corresponding vibrator 11, so that the vibrator 11 can drive the metering box 12 to vibrate, providing accuracy of the amount of raw material in the inner cavity of the metering box 12.

[0025] As a preferred embodiment, four sets of positioning grooves 18 are respectively opened on both sides of the upper surface of the housing 1 along the length direction at equal intervals. The number and position of the positioning grooves 18 correspond one-to-one with the transmission columns 17, and the bottom dimensions of the positioning grooves 18 are adapted to the dimensions of the transmission columns 17.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The dimensions of the positioning groove 18 and the transmission column 17 are matched, which helps to enhance the stability of the transmission column 17 when it rotates. The opening of the positioning groove 18 also facilitates the quick loading and unloading of various components in the quantitative feeding device. The spring and buffer block 15 sleeved on the guide rod 16 can not only help to enhance the stability of the quantitative box 12 when it vibrates, but also help to limit the range of movement of the quantitative box 12, ensuring that the inner cavity of the quantitative box 12 can be filled with raw materials.

[0027] As a preferred embodiment, the mounting plate 8 has a U-shaped structure, the lower surface of the mounting plate 8 is fixedly connected to a sealing layer, and the mounting ring 7 fixedly connected to the outer side of the mounting plate 8 has a U-shaped structure. The mounting ring 7 is fixedly connected to the box body 1 by symmetrically distributed bolts. At the same time, the lower surface of the storage box 9 is positioned relative to the transition groove by a solenoid valve to open a discharge port.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The sealing layer is made of soft rubber, which helps to enhance the sealing of the contact surfaces between the mounting plate 8 and the fixed frame 4 and the upper surface of the partition plate 2. At the same time, the installation ring 7 helps to enhance the stability of the connection between the mounting plate 8 and the box 1.

[0029] In a preferred embodiment, two sets of main sealing strips 6 are fixedly connected to the upper surface of the housing 1. Both sets of main sealing strips are in the shape of a square, and the two sets of main sealing strips 6 are combined to form a U-shaped structure. Two sets of secondary sealing strips are symmetrically connected to the upper surface of the partition plate 2. Both sets of secondary sealing strips are in the shape of long strips, and the cross-sections of the main sealing strips 6 and the secondary sealing strips are in the shape of a semi-circular structure.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The main sealing strip 6 and the secondary sealing strip can further enhance the sealing performance of the sealing layer at the contact point with the upper surface of the fixed frame 4 and the partition plate 2, ensure the safety of each raw material in the transition groove, and ensure that each raw material can be accurately and quantitatively fed through the metering box 12, thereby improving the finished product quality of the lubricating powder.

Furthermore, the internal cavity capacity of different quantitative boxes 12 can be conveniently adjusted by adjusting the lead screw 10 and the adjusting plate 13. At the same time, the positioning rod fixedly connected to the lower surface of the adjusting plate 13 passes through the bottom of the internal cavity of the quantitative box 12 and has a corresponding positioning hole, thereby helping to enhance the stability of the adjusting plate 13 when it moves.
