Description

Technical Field

[0001] The invention belongs to the technical field of Chinese medicinal material pulverization, and in particular relates to a device for preparing superfine Chinese medicinal powder for animal health care. Background Art

[0002] The pharmacological effects of traditional Chinese medicine preparations are also closely related to their physical state. Changing the unit size of drug powder is an effective way to change its physical state. As the particle size of drug powder decreases, the number of atoms on the powder surface increases rapidly, which leads to an increase in surface energy. In this way, due to the high chemical activity of drug powder, its pharmaceutical activity and medicinal properties are enhanced, which is conducive to the rapid absorption of the active ingredients inside by animals, thereby improving utilization.

[0003] At present, when preparing ultrafine powder of traditional Chinese medicine, the traditional Chinese medicine enters the crushing box along the feed hopper, and the crushing roller performs preliminary crushing on the material. The crushed traditional Chinese medicine falls into the placement trough under the action of gravity, and the output shaft of the driving motor drives the turntable to rotate. The turntable drives the extrusion block to move up and down through the guide column, the sliding frame and the connecting rod to perform secondary crushing on the material. At the same time, the output end of the rotating motor drives the crushing rod to rotate through the rotating shaft to crush the traditional Chinese medicine. The rotating shaft drives the output roller to rotate through the first bevel gear and the second bevel gear, which facilitates the transportation of the material and achieves uniform crushing. However, when the above device prepares ultrafine powder, the medicinal materials are easily piled up, and the powder is easy to clog the channel, resulting in the device being unable to run smoothly, and it is impossible to ensure that the specifications of the final product remain consistent.

When the Chinese medicine moves to the end, it falls between the crushing teeth 1 4 and the crushing teeth 2 5 on both sides rotate under the action of the external motor to crush the moving Chinese medicine.

[0052] like Figure 1 and Figure 2 As shown, as another preferred embodiment of the present invention, the primary grinding mechanism 200 includes a fixed plate 8, a sieve hole 9, a screw 10, a screw sleeve 11, a longitudinal rod 12, a grinding roller 13 and a horizontal rod 14;

[0053] The fixing plate 8 is fixedly mounted on the inner wall of the box body 1, and the fixing plate 8 is provided with evenly distributed sieve holes 9;

[0055] A horizontal rod 14 is also installed on the side of the longitudinal rod 12, and the horizontal rod 14 is slidably connected to the box body 1;

[0056] The middle and both sides of the fixing plate 8 are provided with raised parts so that the Chinese medicine particles can stop on the horizontal planes on both sides.

[0057] In one embodiment of the present invention, the longitudinal rotating shaft 6 drives the screws 10 on both sides to rotate along the box body 1 through the transmission box 7 when it rotates. When the screw 10 rotates, it pushes the screw sleeve 11, the longitudinal rod 12 and the horizontal rod 14 to slide in the horizontal direction along the box body 1. The grinding roller 13 moves along the fixed plate 8 while moving with the longitudinal rod 12, grinding the traditional Chinese medicine that falls on the surface of the fixed plate 8 after being crushed, and the powder continues to move downward through the sieve hole 9.

[0058] like Figure 1 and Figure 3 As shown in FIG. 1 , as another preferred embodiment of the present invention, the secondary fine grinding mechanism 300 includes a grinding disc 15 , a second sieve hole 16 , a horizontal shaft 17 and a grinding roller 18 ;

[0059] The grinding disc 15 is fixedly mounted on the inner wall of the box body 1 and is located at the bottom of the fixed plate 8. A second sieve hole 16 is partially opened on the grinding disc 15. The aperture of the second sieve hole 16 is smaller than that of the first sieve hole 9.

[0060] The horizontal shaft 17 is fixedly connected to the surface of the longitudinal rotating shaft 6, and a grinding roller 18 is rotatably mounted on the horizontal shaft 17;

[0061] The cross section of the grinding disc 15 is an isosceles trapezoid, with the middle portion being higher than the two sides to facilitate downward movement of the powder.

[0062] In one embodiment of the present invention, the surfaces of the grinding disc 15 and the grinding roller 18 can be evenly arranged with protrusions as needed to increase the grinding contact area, thereby improving the grinding efficiency. When the longitudinal rotating shaft 6 rotates, the transverse shaft 17 and the grinding roller 18 rotate accordingly, and the grinding roller 18 also rotates along the transverse shaft 17 to grind the powder on the grinding disc 15 again. The ultrafine powder that meets the aperture of the sieve hole 16 passes through the sieve hole 16 and falls downward, and the powder that is larger than the aperture of the sieve hole 16 moves downward along the surface of the grinding disc 15 and finally passes through the box 1 into the reflux mechanism 600.

[0063] like Figure 1 As shown, as another preferred embodiment of the present invention, the exhaust gas collecting mechanism 400 includes a tapered cover 19, a guide pipe 20, a powder collecting cylinder 21 and a cover plate 22;

[0064] The tapered cover 19 is arranged on the inner wall of the box 1 to collect the powder after the secondary fine grinding;

[0065] The outlet pipe 20 is installed on the box body 1 and communicates with the tapered cover 19. A powder collecting cylinder 21 is arranged at the bottom end of the outlet pipe 20. A cover plate 22 is inserted into the powder collecting cylinder 21 on the outside of the outlet pipe 20. The surface of the cover plate 22 is provided with dense air holes.

[0066] In one embodiment of the present invention, the ground powder passes through the sieve hole 16 and falls on the surface of the tapered cover 19, moves downward along the surface of the tapered cover 19, and finally falls into the powder collecting tube 21 through the outlet pipe 20, and the gas can be discharged outward through the dense air holes provided on the surface of the cover plate 22.

[0067] like Figure 1 and Figure 4 As shown in FIG. 5 , as another preferred embodiment of the present invention, the link mechanism 500 includes an oblique rod 23 , a rocking rod 24 , an elastic rod 25 , a movable rod 26 and a guide rod 27 ;

[0068] The inclined rod 23 is fixedly mounted on the outside of the box body 1, and a swing rod 24 is hinged on the inclined rod 23, and the swing rod 24 abuts against an elastic rod 25 arranged on the box body 1;

[0069] The side of the swing rod 24 is fixedly connected to a movable rod 26, and the movable rod 26 abuts against a guide rod 27 slidably mounted on the box body 1;

[0070] A stopper is mounted on the guide rod 27 , and the stopper contacts the grinding disc 15 during movement.

[0071] In one example of the present invention, when the horizontal rod 14 moves along the box body 1, the horizontal rod 14 can push the rocker arm 24 to swing along the oblique rod 23, and the elastic rod 25 is elastically deformed under the force, and the rocker arm 24 drives the movable rod 26 at the bottom end to move synchronously, and the movable rod 26 pushes the guide rod 27 to slide in the height direction along the box body 1. The guide rod 27 intermittently hits the fixed plate 8 and the grinding disc 15 during sliding, and the tapered cover 19 vibrates accordingly, which can prevent powder from accumulating in the sieve hole 1 9 and the sieve hole 2 16, and accelerate the movement of powder along the tapered cover 19, which can prevent blockage inside the device while increasing the speed of powder movement.

[0072] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the reflux mechanism 600 includes a hollow shell 28, a conveying roller 29, a conveyor belt 30, a receiving plate 31, a through hole 32, a shell 33 and a slanted plate 34;

[0073] The hollow shell 28 is arranged outside the box body 1, and the top and bottom of the hollow shell 28 are rotatably mounted with conveying rollers 29, and the top conveying roller 29 is fixedly connected to the lead screw 10;

[0074] The conveyor roller 29 is provided with a conveyor belt 30, and a material receiving plate 31 is provided on the outer surface of the conveyor belt 30. When the external motor rotates forward and reverse, the material receiving plate 31 only needs to be arranged on the outer half of the conveyor belt 30, which can effectively reduce the processing cost.

[0075] The hollow shell 28 is provided with a through hole 32, which is connected to a shell 33 arranged on the side;

[0076] An inclined plate 34 is installed in the housing 33 , and the inclined plate 34 is communicated with a groove provided on the box body 1 , so that the refluxed powder can pass through the groove and enter the box body 1 .

[0077] In one embodiment of the present invention, a space is provided in the hollow shell 28 for the movement of the horizontal rod 14 and the elastic rod 25 to avoid movement interference. The powder at the end of the grinding disc 15 falls on the receiving plate 31 at the bottom. The screw 10 also drives the conveying roller 29 at the top to rotate during movement. The conveying roller 29 drives the conveyor belt 30 and the receiving plate 31 to move synchronously. After the powder moves to the top, it is thrown out under the action of inertia. The powder passes through the through hole 32 and falls on the inclined plate 34 installed in the outer shell 33, and moves along the inclined plate 34 and finally passes through the groove on the box body 1 to re-enter the interior of the box body 1.

[0078] In summary, Chinese medicine is added into the box body 1 through the feed hopper 2, and falls on the V-shaped plate 3 under the action of gravity, and moves along the surface of the V-shaped plate 3. When the Chinese medicine moves to the end, it falls between the crushing teeth 1 4 and the crushing teeth 2 5 on both sides rotate under the action of the external motor to crush the moving Chinese medicine. The crushed Chinese medicine falls on the fixed plate 8. When the longitudinal shaft 6 rotates, it drives the screws 10 on both sides to rotate along the box body 1 through the transmission box 7. When the screw 10 rotates, it pushes the screw sleeve 11, the longitudinal rod 12 and the horizontal rod 14 to slide in the horizontal direction along the box body 1. The grinding roller 13 moves with the longitudinal rod 12 at the same time. It rolls along the fixed plate 8 to grind the Chinese medicine that falls on the surface of the fixed plate 8 after being crushed, and the powder continues to move downward through the sieve hole 9. When the longitudinal rotating shaft 6 rotates, the transverse shaft 17 and the grinding roller 18 rotate accordingly. The grinding roller 18 also rotates along the transverse shaft 17 to grind the powder on the grinding disc 15 again. The ultrafine powder that meets the aperture of the sieve hole 16 passes through the sieve hole 16 and falls downward. The powder that is larger than the aperture of the sieve hole 16 moves downward along the surface of the grinding disc 15. The ground powder passes through the sieve hole 16 and falls on the surface of the tapered cover 19, and moves downward along the surface of the tapered cover 19, and finally falls into the powder collecting tube 21 through the outlet pipe 20, and also when the screw 10 rotates. The conveying roller 29 is driven to rotate, and the conveying roller 29 drives the conveyor belt 30 and the receiving plate 31 to move synchronously. After the powder moves to the top, it is thrown outward under the action of inertia, and the powder passes through the through hole 32 and falls on the inclined plate 34 installed in the shell 33, and moves along the inclined plate 34 and finally re-enters the interior of the box body 1. When the horizontal rod 14 moves, it pushes the swing rod 24 to swing along the inclined rod 23. The elastic rod 25 is elastically deformed under the force, and the swing rod 24 drives the movable rod 26 at the bottom to move synchronously. The movable rod 26 pushes the guide rod 27 to slide in the height direction along the box body 1. The guide rod 27 intermittently hits the fixed plate 8 and the grinding disc 15 during sliding, and the tapered cover 1 9 then vibrates, which can prevent powder from accumulating in sieve hole 1 9 and sieve hole 2 16, and accelerate the powder to move along the tapered cover 19; this device can not only perform primary crushing of traditional Chinese medicine, but also grind it in grades, and avoid the accumulation of traditional Chinese medicine, thereby improving the efficiency of grinding; during the grinding process, the fixed plate 8 and the grinding disc 15 can be intermittently pushed to move, so as to prevent the powder from clogging sieve hole 1 9 and sieve hole 2 16, while accelerating the powder to move along the tapered cover 19, thereby ensuring the smooth operation of the device; it can realize the automatic collection of ultrafine powder, and can also re-send the powder that does not meet the aperture of sieve hole 2 16 into the box body 1, and the processing cost is low, and it can also effectively avoid the occurrence of motion interference.
