[0002] A grinder is a device for preparing powdered materials and is widely used in the coatings, chemical, pharmaceutical, energy, mining and other industries. When using a sand mill, materials are added into a limited barrel space and ground with a stirring rod or steel ball until the material in the barrel reaches the target particle size.

A rectangular hole is provided on the surface of the grinding barrel, and a return pipe is fixedly installed in the discharge hole and the rectangular hole, and a sealing component is provided in the return pipe.

[0009] As a preferred solution, one end of the rotating shaft passes through the feed pipe, and the driving assembly includes a driving motor fixedly mounted on the upper end of the grinding barrel, two transmission wheels respectively fixedly sleeved on the output shaft of the driving motor and fixedly sleeved on the rotating shaft, and a transmission belt sleeved on the two transmission wheels.

[0010] As a preferred solution, one end of the reflux pipe is in a sealed state, and a strip hole is opened on the lower surface of the reflux pipe located in the grinding barrel. The sealing assembly includes a first telescopic spring fixedly installed in the reflux pipe, a push plate slidably installed in the reflux pipe, and a block fixedly installed on the inner wall of the feed pipe. The first telescopic spring is fixedly connected to the push plate.

[0011] As a preferred solution, support rods are symmetrically fixedly installed on the rotating shaft, and one end of each of the support rods is provided with a mounting groove. A moving rod is slidably installed in each of the two mounting grooves through a second telescopic spring. A scraper is fixedly installed at one end of each of the two moving rods, and both of the scrapers are in sliding contact with the inner wall of the feed pipe with filter holes. A limiting component is provided at the upper end of the feed pipe for driving the moving rod to move toward the rotating shaft.

[0012] As a preferred solution, the surfaces of the two support rods are respectively provided with movable holes connected to the two mounting grooves, and the limiting assembly includes an arc-shaped limit block fixedly installed on the top of the feeding tube and a baffle fixedly installed on the movable rod, and one end of the baffle passes through the movable hole and intermittently contacts the arc surface of the arc-shaped limit block.

[0013] As a preferred solution, an annular hole is opened on the upper surface of the annular silo, a scraper is slidably installed in the annular silo, an L-shaped connecting rod is fixedly installed on the scraper, and one end of the connecting rod passes through the annular hole and is fixedly connected to the rotating shaft.

[0014] As a preferred solution, a circular ring is fixedly installed in the annular silo through a mounting rod, and a plurality of triangular blocks with right-angled triangle cross sections are fixedly installed on the side of the circular ring. A support block is fixedly installed on the upper end of the scraper, and a movable hole is opened on the surface of the support block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the grinding rod is grinding the material in the grinding barrel, the material will enter the feed pipe through the guide tube under the action of centrifugal force, and then the material in the feed pipe will be driven upward by the action of the rotating shaft and the spiral blade. At this time, the material at the upper end of the feed pipe continues to increase, and the pressure becomes greater. Under the stirring of the stirring plate, the material will move toward the filter hole, and then the material reaching the required diameter will pass through the filter hole and enter the annular silo for discharge. As the pressure continues to increase, the sealing component will open the reflux pipe, and the material in the feed pipe will enter the grinding barrel again for grinding. Therefore, while the material is fully ground, the material can be automatically discharged. The operation is simple and the material grinding production efficiency is effectively improved.

[0017] 2. When the rotating shaft rotates, the support rod, the moving rod and the second telescopic spring cooperate with each other to drive the scraper to move along the inner wall of the feeding pipe. During the movement, the scraper cleans the inner wall of the feeding pipe with filter holes to prevent some materials with larger diameters from blocking the filter holes.

[0018] 3. When the rotating shaft drives the scraper to rotate half a circle, the stop rod will contact the arc-shaped limit block. Under the action of the arc surface, the scraper will be driven to move toward the rotating shaft through the moving rod, thereby separating the scraper from the inner wall of the feed tube, reducing the contact between the scraper and the inner wall of the feed tube during rotation, thereby reducing the wear on the scraper and effectively improving the service life of the scraper;

[0019] 4. During the rotation of the scraper, the vertical rod will be driven to continuously contact the inclined surface of the triangular block. When the vertical rod is in contact with the inclined surface of the triangular block, the impact rod and the punch block will be driven away from the feed pipe under the action of the inclined surface. When the vertical rod is separated from the triangular block, the third telescopic spring will be used to drive the punch to quickly hit the part of the feed pipe where the filter hole is opened. The feed pipe will vibrate under the impact of the punch, which will help the material in the feed pipe to pass through the filter hole and enter the annular silo. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figures 1-8A material flow pulsating impeller pump in a multi-axis grinding machine includes a base 1, a grinding barrel 2 is fixedly installed on the upper end of the base 1, multiple rotating shafts 3 are rotatably installed in the grinding barrel 2, multiple grinding rods 4 are fixedly installed on the multiple rotating shafts 3, and a driving device 5 for driving the multiple rotating shafts 3 to rotate simultaneously is installed in the base 1.

[0031] When grinding the material, the material is first added into the grinding barrel 2, and then the driving device 5 drives the multiple rotating shafts 3 to rotate, and then the multiple rotating shafts 3 drive the multiple grinding rods 4 to rotate in the grinding barrel 2, thereby achieving the grinding of the material.

[0032] A feeding pipe 6 is fixedly installed on the side of the grinding barrel 2, and a feeding port is opened at the lower end of the feeding pipe 6. A guide tube 7 is fixedly installed in the feeding port. One end of the guide tube 7 is communicated with the grinding barrel 2. A rotating shaft 8 is rotatably installed in the feeding pipe 6, and a spiral blade 9 is fixedly sleeved on the rotating shaft 8. A plurality of stirring plates 19 are fixedly installed on the rotating shaft 8. A driving assembly for driving the rotating shaft 8 to rotate is provided at the upper end of the grinding barrel 2. One end of the rotating shaft 8 passes through the feeding pipe 6. The driving assembly includes a driving motor 13 fixedly installed on the upper end of the grinding barrel 2, two transmission wheels 14 respectively fixedly sleeved on the output shaft of the driving motor 13 and fixedly sleeved on the rotating shaft 8, and a transmission belt 15 sleeved on the two transmission wheels 14. An annular silo 10 is fixedly sleeved on the end portion, and a plurality of filter holes are provided at the connection portion between the feed pipe 6 and the annular silo 10. A discharge pipe 11 is fixedly connected to the lower surface of the annular silo 10, a discharge hole is provided on the surface of the feed pipe 6, and a rectangular hole is provided on the surface of the grinding barrel 2. A return pipe 12 is fixedly installed in the discharge hole and the rectangular hole, and a sealing component is provided in the return pipe 12. One end of the return pipe 12 is in a sealed state, and a strip hole is provided on the lower surface of the return pipe 12 located in the grinding barrel 2. The sealing component includes a first telescopic spring 16 fixedly installed in the return pipe 12, a push plate 17 slidably installed in the return pipe 12, and a stopper 18 fixedly installed on the inner wall of the feed pipe 6. The first telescopic spring 16 is fixedly connected to the push plate 17.

[0033] During the grinding process, the material at the bottom of the grinding barrel 2 will enter the feed pipe 6 from the guide tube 7 under the action of centrifugal force. Under the action of the driving motor 13, the transmission belt 15 can drive the transmission wheel 14 fixedly sleeved on the rotating shaft 8 to rotate, thereby driving the rotating shaft 8 to rotate, and then the rotating shaft 8 drives the spiral blade 9 to rotate. Under the action of the spiral blade 9, the material in the feed pipe 6 will be driven to move upward. At this time, under the action of the elastic force of the first telescopic spring 16, the push plate 17 contacts the stopper 18, thereby blocking the pipe mouth of the return pipe 12. As the material continues to rise, the material at the upper end of the feed pipe 6 gradually increases, the pressure becomes greater, and the rotating shaft When 8 rotates, it drives multiple stirring plates 19 to rotate. Under the action of the stirring plates 19, the material will be pushed to move toward the filter hole. As the pressure continues to increase, some materials that reach the required diameter will pass through the filter hole into the annular silo 10, and then be discharged through the discharge pipe 11. As the amount of material increases, the material will also push the push plate 17 to move in the direction of the first telescopic spring 16 until the push plate 17 moves to the strip hole. The material will pass through the strip hole into the grinding barrel 2 to continue grinding, so that while the material is fully ground, the material can be automatically discharged, the operation is simple, and the grinding production efficiency of the material is effectively improved.

[0034] Support rods 20 are symmetrically fixedly installed on the rotating shaft 8, and one end of the two support rods 20 is provided with a mounting groove. A moving rod 22 is slidably installed in the two mounting grooves through a second telescopic spring 21. A scraper 23 is fixedly installed at one end of the two moving rods 22. The two scrapers 23 are in sliding contact with the inner wall of the feed pipe 6 with filter holes. The upper end of the feed pipe 6 is provided with a limit assembly for driving the moving rod 22 to move toward the rotating shaft 8. The surfaces of the two support rods 20 are respectively provided with moving holes connected to the two mounting grooves. The limit assembly includes an arc-shaped limit block 24 fixedly installed on the top of the feed pipe 6 and a baffle 25 fixedly installed on the moving rod 22. One end of the baffle 25 passes through the moving hole and intermittently contacts the arc surface of the arc-shaped limit block 24.

[0035] When the rotating shaft 8 rotates, it will drive the two support rods 20 to rotate. Under the action of the elastic force of the second telescopic spring 21, the moving rod 22 will drive the scraper 23 to slide in contact with the inner wall of the feed pipe 6 with filter holes. The scraper 23 will rotate together with the rotating shaft 8. During the rotation, the scraper 23 will scrape off the larger diameter materials blocked in the filter holes, thereby cleaning the inner wall of the feed pipe 6 with filter holes and preventing some larger diameter materials from blocking the filter holes.

[0036] When the moving rod 22 rotates with the rotating shaft 8, the blocking rod 25 will intermittently contact the arc-shaped limit block 24. Under the restriction of the arc surface of the arc-shaped limit block 24, when the blocking rod 25 contacts the arc-shaped limit block 24, it will drive the moving rod 22 to move in the direction of the second telescopic spring 21, thereby driving the scraper 23 to separate from the inner wall of the feeding pipe 6, reducing the contact of the scraper 23 with the inner wall of the feeding pipe 6 during rotation, thereby reducing the wear on the scraper 23 and effectively improving the service life of the scraper 23. When the blocking rod 25 is separated from the arc-shaped limit block 24, under the action of the elastic force of the second telescopic spring 21, the moving rod 22 will drive the scraper 23 to contact the inner wall of the feeding pipe 6 and impact it to produce vibration. Under the vibration, the material in the feeding pipe 6 is facilitated to pass through the filter hole and enter the annular silo 10.

[0037] An annular hole is provided on the upper surface of the annular silo 10, and a scraper 26 is slidably installed in the annular silo 10, and an L-shaped connecting rod 27 is fixedly installed on the scraper 26, and one end of the connecting rod 27 passes through the annular hole and is fixedly connected to the rotating shaft 8, and a circular ring 28 is fixedly installed in the annular silo 10 through a mounting rod, and a plurality of triangular blocks 29 with a right-angled triangular cross-section are fixedly installed on the side of the circular ring 28, and a support block 30 is fixedly installed on the upper end of the scraper 26, and a movable hole is provided on the surface of the support block 30, and an impact rod 31 is slidably installed in the movable hole, and a punch 32 is fixedly installed on one end of the impact rod 31, and a third telescopic spring 33 is sleeved on the impact rod 31, and the two ends of the third telescopic spring 33 are fixedly connected to the punch 32 and the support block 30 respectively, and a support rod 34 is fixedly installed on the punch 32, and a vertical rod 35 is fixedly installed on the surface of the support rod 34, and the vertical rod 35 is intermittently in contact with the inclined surfaces of the plurality of triangular blocks 29.

[0038] When the rotating shaft 8 rotates, it will drive the scraper 26 to rotate in the annular silo 10 through the connecting rod 27. Under the action of the scraper 26, the material passing through the filter hole can be pushed into the discharge pipe 11 to achieve unloading. While driving the scraper 26 to rotate, the connecting rod 27 will drive the vertical rod 35 to continuously contact the multiple triangular blocks 29 fixedly mounted on the ring 28. When the vertical rod 35 contacts the inclined surface of the triangular block 29, it will drive the punch 32 to move away from the feed pipe 6 through the support rod 34. The punch 32 then drives the impact rod 31 to move, and the third telescopic spring 33 is compressed until the vertical rod 35 is separated from the triangular block 29. Under the action of the elastic force of the third telescopic spring 33, the impact rod 31 will drive the punch 32 to quickly hit the part of the feed pipe 6 where the filter hole is opened. The feed pipe 6 vibrates under the impact of the punch 32. Under the vibration, the material in the feed pipe 6 is facilitated to pass through the filter hole and enter the annular silo 10, and the material in the filter hole of the card slot can be shaken down to avoid clogging of the filter hole.

[0039] The material at the bottom of the grinding barrel 2 is fed into the feeding pipe 6 through the guide tube 7 under the action of centrifugal force. Under the action of the driving component, the rotating shaft 8 drives the spiral blade 9 to rotate, thereby driving the material in the feeding pipe 6 to move upward. As the material continues to rise, the material at the upper end of the feeding pipe 6 gradually increases, and the pressure increases. When the rotating shaft 8 rotates, it drives multiple stirring plates 19 to rotate. Under the action of the stirring plates 19, the material will be pushed to move toward the filter hole. As the pressure continues to increase, some materials that reach the required diameter will pass through the filter hole and enter the annular silo 10, and then be discharged through the discharge pipe 11. As the material increases, the blocking component will automatically open the mouth of the return pipe 12, and then the material will enter the grinding barrel 2 again to continue grinding. Therefore, while the material is fully ground, the material can be automatically discharged. The operation is simple and the grinding production efficiency of the material is effectively improved.
