Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine processing technology, and more specifically, to a powder sieving machine. Background Technology

[0002] After Chinese medicine is ground into powder, it needs to be sieved to collect the powder that meets the fineness requirements for subsequent processing. Existing sieving machines typically vibrate the sieve screen to cause the powder to fall, and generally, the vibration direction is fixed.

[0003] For example, the invention patent with publication number CN108080250A and patent name "Traditional Chinese Medicine Powder Sieving Machine" describes a technical solution in which the screen is set in the cylinder, and the vibration of the vibrating body causes the cylinder to drive the screen to vibrate, so that the smaller powder particles fall from the screen.

[0004] This screening method uses a vibrating block to vibrate the cylinder. Since the cylinder vibrates in a single way, the screen also vibrates in a single way. During the vibration process, the powder tends to clump together under this single vibration mode, which reduces the screening efficiency. Summary of the Invention

[0051] Feed inlet 6 is connected to the outer wall of the vibrating screen powder box 5.

[0052] In this technical solution, by setting up a vibrating sieve powder box 5, the Chinese medicine powder can be directly poured into the vibrating sieve powder box 5. Through the vibration of the vibrating sieve powder box 5, the Chinese medicine powder is sieved inside by vibration, which improves the utilization rate of the entire sieve.

[0061] In this technical solution, the lid 14 can be opened automatically by gravity, and after collection is completed, it can be closed automatically by the contact of the baffle 8.

[0062] It is worth noting that the support base 1 also has a cavity 17 inside, and a driving block 18 is slidably arranged inside the cavity 17.

An eccentric wheel 22 is rotatably installed on one end of the push rod 21 via a pin.

[0064] In this technical solution, by setting up the drive block 18, it can push the sorting hopper 9, thereby automatically controlling the discharge of the sorting hopper 9 and improving the degree of automation.

[0065] It is worth noting that in this embodiment, the vibration assembly includes a first worm gear 24, which is fixedly mounted on one side of the outer wall of the support frame 4 via a fixing lug 25.

[0069] In this technical solution, the vibrating screen powder box 5 can be driven to rotate and vibrate in both the inner and outer directions.

[0070] Example 2

[0071] The difference between the powder screening machine provided in this embodiment and that in embodiment 1 is that the vibration component in this embodiment is different from that in embodiment 1. In this embodiment, the vibration component includes a second worm 30, which is fixedly mounted on one side of the outer wall of the support frame 4 by means of a fixing lug 25.

[0072] One end of the second worm gear 30 is coaxially connected and fixed to the third motor 31, which is fixedly installed on the outside of the support frame 4;

[0073] The outer wall of the second worm 30 is meshed with a second incomplete worm wheel 32, and the shaft of the second incomplete worm wheel 32 is fixedly mounted on the outer wall of the adjusting plate 27 via a fixing lug 25.

[0074] The outer wall of the shaft of the second incomplete worm gear 32 is fixedly provided with an adjustment support rod 33. At least one roller 34 is rotatably provided at the outer end of the adjustment support rod 33 via a pin. A support frame 35 is fixedly provided on the outer wall of the roller 34. The support frame 35 is fixedly provided on the outer wall of the adjustment plate 27.

[0075] In this technical solution, the vibrating screen powder box 5 can be driven to rotate and vibrate in the left and right directions.

[0076] In addition, there are two rollers 34. The outer wall of the rollers 34 is provided with anti-misalignment grooves 36. One side of the support frame 35 is cylindrical and is adapted to the arc-shaped structure of the anti-misalignment grooves 36.

[0077] The support frame 35 is U-shaped, and the roller 34 is located on the side of the support frame 35 near the adjustment plate.

[0078] This technical solution effectively reduces friction and limits the oscillation, preventing the vibrating screen box 5 from shifting and improving its overall lifespan.

[0079] Example 3

[0080] The difference between the powder screening machine provided in this embodiment and that in embodiment 1 is that the vibration component in this embodiment is different from that in embodiment 1. In this embodiment, the vibration component includes a first worm 24, which is fixedly mounted on one side of the outer wall of the support frame 4 by a fixing lug 25.

[0081] One end of the first worm gear 24 is coaxially connected and fixed to the second motor 26, which is fixedly installed on the outside of the support frame 4;

[0082] An adjusting plate 27 is rotatably provided on the outer wall of the first worm gear 24, and a connecting shaft 28 is rotatably provided on one side of the adjusting plate 27. The connecting shaft 28 is fixedly provided on the outer wall of the vibrating screen powder box 5 through a fixing lug 25.

[0083] A first incomplete worm gear 29 is fixedly installed at one end of the connecting shaft 28, and the first incomplete worm gear 29 is meshed with the first worm 24.

[0084] The vibration assembly also includes a second worm gear 30, which is fixedly mounted on one side of the outer wall of the support frame 4 via a fixing lug 25;

[0085] One end of the second worm gear 30 is coaxially connected and fixed to the third motor 31, which is fixedly installed on the outside of the support frame 4;

[0086] The outer wall of the second worm 30 is meshed with a second incomplete worm wheel 32, and the shaft of the second incomplete worm wheel 32 is fixedly mounted on the outer wall of the adjusting plate 27 via a fixing lug 25.

[0087] The outer wall of the shaft of the second incomplete worm gear 32 is fixedly provided with an adjustment support rod 33. At least one roller 34 is rotatably provided at the outer end of the adjustment support rod 33 via a pin. A support frame 35 is fixedly provided on the outer wall of the roller 34. The support frame 35 is fixedly provided on the outer wall of the adjustment plate 27.

[0088] In addition, there are two rollers 34. The outer wall of the rollers 34 is provided with anti-misalignment grooves 36. One side of the support frame 35 is cylindrical and is adapted to the arc-shaped structure of the anti-misalignment grooves 36.

[0089] The support frame 35 is U-shaped, and the roller 34 is located on the side of the support frame 35 near the adjustment plate.

[0090] This technical solution effectively reduces friction and limits the oscillation, preventing the vibrating screen box 5 from shifting and improving its overall lifespan.

[0091] In this technical solution, the vibration component can drive the vibrating screen powder box 5 to rotate and vibrate in both the inward and outward directions, as well as in the left and right directions, thus diversifying the vibration mode of the vibrating screen powder box and improving its powder screening effect.

[0092] When the powder screening machine is needed, firstly, the Chinese medicine powder is put into the vibrating powder screening box 5 through the feed port 6. At this time, the controller drives the second motor to reciprocate. The output shaft of the second motor 26 rotates and drives the first worm 24 to rotate. The first worm 24 meshes with the first incomplete worm wheel 29, thereby driving the first incomplete worm wheel 29 to rotate back and forth, thereby driving the vibrating powder screening box 5 to swing inside and outside.

[0093] Simultaneously, the third motor 31 is driven to reciprocate. The output shaft of the third motor rotates, which drives the second worm 30 to rotate. The second worm 30 meshes with the second incomplete worm wheel 32, thereby driving the second incomplete worm wheel 32 to rotate back and forth. This causes the adjusting support rod 33, which is fixed on the shaft of the second incomplete worm wheel 32, to swing. At this time, the two anti-misalignment grooves 36, which are rotatably set at one end of the adjusting support rod 33, will slide on the support frame 35, thereby driving the vibrating screen powder box 5 to swing left and right. Rollers 34 are provided on the anti-misalignment grooves 36, which roll on the cylinder of the support frame 35, so that even when the swing force is large, it can still run smoothly and will not derail.

[0094] After the powder sieving is completed, the powder in the collection hopper 3 will reach the classification hopper 9 and fill it quantitatively. At this time, the output shaft of the first motor 23 will rotate, driving the eccentric wheel 22 to rotate, which in turn drives the push rod 21 to push and pull the connecting plate 19 back and forth. When pushed out, the slide plate 10 takes the classification hopper 9 out of the baffle 8. At this time, the lid 14 will open automatically due to gravity. The powder will then be collected by the collection container 2. After that, the connecting plate 19 will be pulled, causing the lid 14 to close automatically due to the resistance of the baffle 8. After the powder is collected, the box door 7 will be opened, and the powder inside will be poured into the collection hopper 3 by swinging, and then classified and collected again by the classification hopper 9.

[0095] Example 4

[0096] This embodiment is an improvement based on embodiments 1-3. In this embodiment, a flexible feeding pipe is fixedly provided on the inner wall of the bottom of the distributing hopper 9. One end of the flexible feeding pipe extends to the upper end of the collecting hopper 2. When the hopper cover 14 abuts against the outer wall of the distributing hopper 9 under the pressure of the baffle, the flexible feeding pipe is squeezed between the hopper cover and the distributing hopper.

[0097] In this technical solution, the flexible feeding pipe allows the powder in the feeding hopper to fall slowly when all the materials are pushed out, and the feeding speed can be manually intervened to prevent the powder from spilling.
