They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Example, refer to Figures 1-13 A pneumatic pipeline conveying device for powder production and packaging includes a pipe body 1, and further includes a moving mechanism 2, a rotating cleaning mechanism 3, a sealing and partitioning mechanism 4 and a driving mechanism 5, one end of the driving mechanism 5 being connected to the moving mechanism 2.

[0038] The moving mechanism 2 includes a sleeve 201 fixedly connected to the inside of the tube body 1. A first threaded rod 202 is rotatably connected inside the sleeve 201. A moving block 203 is threadedly connected to the first threaded rod 202. A linkage collar 204 is fixedly connected to one side of the moving block 203. Moving grooves are respectively opened on both sides of the sleeve 201. One side of the moving block 203 is movably fitted into the moving groove on one side. The rotation of the first threaded rod 202 drives the moving block 203 to move axially along the inside of the sleeve 201. The moving groove provides guidance and limiting function for the moving block 203, and at the same time drives the linkage collar 204 to move synchronously along the outside of the sleeve 201.

[0039] The rotary cleaning mechanism 3 includes a connecting rod 301 rotatably connected to one side of the movable block 203. A first gear 302 is fixedly connected to the connecting rod 301. A rack 303 is fixedly connected to one side of the sleeve 201 corresponding to the first gear 302. One side of the first gear 302 meshes with the rack 303 for transmission. The connecting rod 301 is movably sleeved inside the movable groove on the other side. A second gear 307 is fixedly connected to the other end of the connecting rod 301. The movement of the linkage collar 204 drives the connecting rod 301 to move synchronously. At the same time, the first gear 302 meshes with the rack 303 for transmission. The rotation of the first gear 302 drives the connecting rod 301 to rotate synchronously. The rotation of the connecting rod 301 synchronously drives the rotation of the second gear 307.

[0040] The sealing and partitioning mechanism 4 includes an operating box 401 fixedly connected to the pipe body 1. Two partition plates 402 are symmetrically fixedly connected inside the operating box 401. Trapezoidal sliders 403 are fixedly connected to one side of each of the two partition plates 402. Two sealing plates 404 are slidably connected inside the operating box 401. Trapezoidal grooves 405 are opened on one side of each sealing plate 404 corresponding to the trapezoidal sliders 403. The trapezoidal sliders 403 are movably fitted inside the trapezoidal grooves 405. One side of each sealing plate 404 is closely fitted to the partition plate 402. The partition plate 402 divides the inside of the pipe body 1 into two cavities. The two sealing plates 404 move smoothly up and down along the trapezoidal sliders 403 through the trapezoidal grooves 405, thereby sealing and isolating the inside of the pipe body 1.

[0041] The drive mechanism 5 includes a second motor frame fixedly connected to one end of the tube body 1, a second motor 501 fixedly connected to the second motor frame, a first pulley 502 fixedly connected to the output shaft of the second motor 501, and a second pulley 503 fixedly connected to one end of the first threaded rod 202 corresponding to the first pulley 502. The second pulley 503 and the first pulley 502 are externally connected by the same belt 504. When the second motor 501 is started, it drives the first pulley 502 to rotate through the output shaft, and at the same time drives the second pulley 503 to rotate through the belt 504, thereby driving the first threaded rod 202 to rotate. Power is transmitted through belt drive, driving the rotation of the first threaded rod 202 and providing power for the moving mechanism 2.

[0042] In this invention, the rotary cleaning mechanism 3 further includes a linkage frame 304 rotatably connected to both sides of the linkage ring 204. A first toothed ring 305 is fixedly connected to the outer side of each linkage frame 304, and a cleaning plate 306 is fixedly connected to each of the two first toothed rings 305. One side of the cleaning plate 306 abuts against the inside of the tube body 1. One side of each of the two first toothed rings 305 meshes with both sides of the second gear 307 for transmission. The sleeve 201 movably passes through the inside of each of the two first toothed rings 305. The rotation of the second gear 307 drives the rotation of the two first toothed rings 305, which in turn drives the cleaning plates 306 on both sides to rotate synchronously. It is worth noting that when the moving block 203 moves, the first gear 302 meshes with the rack 303 to generate rotational motion, which drives the second gear 307 to rotate via the connecting rod 301, thereby driving the first toothed rings 305 and the cleaning plates 306 on both sides to rotate synchronously, achieving 360° cleaning of the inner wall of the tube body and effectively preventing powder accumulation inside the tube body 1 from causing blockage.

[0043] In this invention, the sealing and partitioning mechanism 4 further includes second threaded rods 406 rotatably connected to the upper and lower sides of the operation box 401, respectively. Lifting blocks are threadedly connected to the two second threaded rods 406, and the two lifting blocks are fixedly connected to one side of the two sealing plates 404. Driven gears 407 are fixedly connected to one end of the two second threaded rods 406, respectively. A first motor frame is fixedly connected to one side of the operation box 401, and a first motor 410 is fixedly connected to the first motor frame. A drive gear 411 is fixedly connected to the output shaft of the first motor 410. One side of the drive gear 411 meshes with the upper driven gear 407 for transmission. The start of the first motor 410 drives the drive gear 411 to rotate through the output shaft. The rotation of the drive gear 411 drives the adjacent driven gear 407 to rotate synchronously. It is worth mentioning that the first motor 410 drives the two sealing plates 404 to move smoothly up and down along the trapezoidal slider 403 through gear transmission, thereby effectively sealing and partitioning the inside of the tube body 1 and preventing powder from entering the area of ​​the rotary cleaning mechanism 3 when not in operation.

[0044] In this invention, a support frame 408 is fixedly connected to the other side of the operating box 401. A second gear ring 409 is rotatably connected to the support frame 408. One side of the second gear ring 409 meshes with two driven gears 407 respectively. A movable groove 413 is opened inside the second gear ring 409. The outer side of the support frame 408 is movably sleeved inside the movable groove 413. Through grooves 412 are opened on the upper and lower sides of the tube body 1 respectively corresponding to the two sealing plates 404. The two sealing plates 404 respectively move through the corresponding through grooves 412. The rotation of one driven gear 407 drives the other driven gear 407 to rotate synchronously through the second gear ring 409. The synchronous rotation of the two driven gears 407 drives the two second threaded rods 406 to rotate.

[0045] In this invention, the top of the tube body 1 is provided with an air inlet and a feed inlet. An air inlet pipe 6 is fixedly connected to the air inlet, and a pressure monitoring instrument 7 is fixedly connected to the air inlet pipe 6. A feed pipe 8 is fixedly connected to the feed inlet, and a control valve 9 is fixedly connected to the feed pipe 8. One end of the tube body 1 is provided with a discharge outlet. An external air inlet pipe is connected to the air inlet pipe 6. Powder is injected into the inside of the tube body 1 through the feed pipe 8. The pressure monitoring instrument 7 monitors the air pressure inside the tube in real time. The air pressure is precisely controlled by the pressure regulating valve. The control valve 9 is used to adjust the feeding speed to adapt to the conveying needs of powders with different characteristics.

[0046] Working principle: During use, during the conveying operation, the sealing plate 404 of the sealing isolation mechanism 4 is closed, so that the rotating cleaning mechanism 3 is in an isolated state;

[0047] Compressed air is introduced through the air inlet pipe 6, monitored by the air pressure monitor 7, and the appropriate air pressure is set by the air pressure regulating valve to effectively and uniformly convey different powders pneumatically.

[0048] At the same time, the control valve 9 of the feed pipe 8 is opened, so that the powder is conveyed to the outlet along the pipe body 1 under the action of air pressure.

[0049] Cleaning operation: After the conveying is completed, close the feed control valve 9 to prevent powder from falling into the tube body 1. After the feed port is closed, start the first motor 410. The start of the first motor 410 drives the drive gear 411 to rotate. The rotation of the drive gear 411 drives the adjacent driven gear 407 to rotate. At the same time, the second gear 409 drives another driven gear 407 to rotate synchronously. The rotation of the two driven gears 407 drives the rotation of the two second threaded rods 406. The rotation of the two second threaded rods 406 drives the lifting block to move, thereby driving the two sealing plates 404 to move, so that the inside of the tube body 1 is opened through both sides. After the sealing plates 404 are opened;

[0050] The second motor 501 is started, which drives the first pulley 502 to rotate. At the same time, the belt 504 drives the second pulley 503 to rotate, which in turn drives the first threaded rod 202 to rotate. The rotation of the first threaded rod 202 drives the moving block 203 to move along the pipe body 1. At the same time, it drives the connecting rod 301 and the connecting collar 204 to move synchronously along the inside of the pipe body 1. When the connecting rod 301 moves, the first gear 302 meshes with the rack 303, which drives the connecting rod 301 and the second gear 307 to rotate. The rotation of the second gear 307 drives the two first gear rings 305 to rotate, which in turn drives the cleaning plate 306 to rotate in a circle. The inner wall of the pipe body 1 is cleaned by the rotation of the cleaning plate 306.

[0051] After cleaning is completed, the second motor 501 is started in reverse to reset the rotating cleaning mechanism 3, and then the first motor 410 is started in reverse to close the sealing plate 404, thereby isolating the two sides inside the tube body 1 again.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
