[0017] Reference Figures 1 to 4 As shown, the present invention provides a quantitative device for precise feeding of lubricating powder, comprising: a box body 1 and a mounting plate 8, wherein the upper end of the inner cavity of the box body 1 is fixedly connected to a fixed frame 4, the inner cavity of the fixed frame 4 is evenly divided into a plurality of transition grooves by a partition plate 2, and a transmission column 17 is movably connected in the transition groove through a sealed bearing, and one end of the transmission column 17 is engaged with a worm gear assembly 20, and the other end of the transmission column 17 is fixedly connected to a rotating cylinder 3 through a fixed plate 19, and the surface of the rotating cylinder 3 is fixedly connected to a limit plate 14 through a through opening, and at the same time, a buffer groove is symmetrically provided on the surface of the limit plate 14, and a guide rod 16 is fixedly connected in the buffer groove, and springs are sleeved at both ends of the guide rod 16, and a buffer block 15 is slidably connected to the middle of the guide rod 16, and the buffer block 15 is fixedly connected The outer side of the quantitative box 12 is connected, and the quantitative box 12 is slidably connected to the surface of the limit plate 14 through the buffer block 15. The bottom of the inner cavity of the quantitative box 12 is screwed with the adjusting screw 10, and the upper end of the adjusting screw 10 is movably connected to the adjusting plate 13 through a sealed bearing, and the adjusting plate 13 is slidably connected in the inner cavity of the quantitative box 12 through the adjusting screw 10. The lower surface of the quantitative box 12 is fixedly connected to the vibrator 11, and the mounting plate 8 is fixedly connected to the upper surface of the box body 1 through the mounting ring 7, and the upper surface of the mounting plate 8 is symmetrically connected to the storage box 9, and the outer side of the quantitative box 12 is movably connected to the worm assembly 20 through a bearing, and the outer side of the quantitative box 12 is fixedly connected to the servo motor 21, and the servo motor 21 is fixedly connected to one end of the worm assembly 20 through a coupling.

[0018] In this embodiment, first, the capacity of the corresponding metering box 12 is determined according to the ratio of the raw materials of the lubricating powder. Then, the adjusting screw rod 10 is rotated. The metering box 12 connected by screwing on the adjusting screw rod 10 can push the adjusting plate 13 to move correspondingly inside the metering box 12, so as to realize the convenient adjustment of the internal cavity capacity of the metering box 12. Moreover, scale lines are provided on the inner side surface of the metering box 12, which can assist in improving the convenience of capacity adjustment. After the adjustment is completed, the storage box 9 is fixedly connected to the upper surface of the box body 1 through the mounting ring 7 and the mounting plate 8. The solenoid valves at the discharge ports of the storage boxes 9 are opened, so that the raw materials in the storage boxes 9 can fall into the corresponding transition grooves. Then, the switch of the vibrator 11 is started, and the vibrator 11 can drive the metering box 12 to vibrate, ensuring that the raw materials can smoothly fill the inner cavity of the metering box 12, and assisting in improving the accuracy of the ratio between the raw materials. Among them, through the cooperation of the guide rod 16, the spring and the buffer block 15, the stability of the vibration between the limiting plate 14 and the metering box 12 can be assisted and enhanced. Then, the switch of the servo motor 21 is started. The output shaft of the servo motor 21 drives the fixedly connected worm assembly 20 to rotate through the coupling. Each worm fixedly connected inside the worm assembly 20 drives the transmission column 17, the fixing plate 19, the rotating cylinder 3, the limiting plate 14 and the metering box 12 to rotate synchronously and at a low speed through the correspondingly meshing worm wheels. After the rotating cylinder 3 rotates one circle, the servo motor 21 is periodically turned off. When the opening of the metering box 12 communicates with the lower end of the inner cavity of the box body 1, the raw materials in the inner cavity of the metering box 12 can quickly slide down under the dual action of gravity and vibration, so as to improve the accuracy of the ratio between the raw materials of the lubricating powder and improve the quality of the lubricating powder finished product.

At the same time, the transmission column 17 with a hollow structure is convenient for fixing the plug interface through the cover plate. The plug interface is electrically connected to the battery fixedly connected in the rotating drum 3, which is convenient for charging the battery. The battery is electrically connected to the corresponding vibrator 11, so that the vibrator 11 can drive the quantitative box 12 to vibrate, providing the accuracy of the raw material amount in the inner cavity of the quantitative box 12.
