Description

Technical Field

[0001] The present invention belongs to the technical field of pulverizing devices, and more specifically, particularly relates to a pulverizing device for processing Chinese medicinal materials with a screening function. Background Art

[0002] Chinese medicinal materials refer to medicinal materials produced in a region with specific natural conditions and ecological environment. Due to the relatively concentrated production, the cultivation technology, harvesting and processing also have certain requirements, so that the quality and efficacy of the same medicinal materials produced in other regions are better. Chinese medicinal materials are generally crushed during processing to make their particle size more uniform, making them easier to be absorbed by the gastrointestinal tract.

[0003] However, the existing pulverizing devices for processing Chinese medicinal materials with screening function still have the following shortcomings when used: 1.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing a slide groove, a half gear, a loading plate, a rack, a fixed bar and a spring, the two half gears will drive the two racks meshing therewith to slide to the left under the rotation of the two half gears, and at this time the two racks will drive the loading plate to slide outward inside the slide groove, and at this time the loading plate will drive the fixed bar fixed therewith to move accordingly, and the fixed bar squeezes the two springs to compress them, and when the two half gears rotate to a state of misalignment with the rack, at this time the two springs restore elastic potential energy to drive the fixed bar and the loading plate to reset, so that when the equipment is operating, the loading plate can slide back and forth inside the slide groove, and this reciprocating motion can not only continuously transport Chinese medicinal materials, but also impact and evacuate the possible accumulation area of ​​Chinese medicinal materials during the resetting process, if a small amount of Chinese medicinal materials are locally gathered inside the equipment, the resetting motion of the loading plate will break up these gathered Chinese medicinal materials and make them return to the normal flow path of Chinese medicinal materials, thereby effectively preventing the blockage caused by the accumulation of Chinese medicinal materials and ensuring the long-term stable operation of the equipment; In the present invention, a collecting box, a driving motor, an inner column, a gear synchronous belt, a bevel gear, a first fixed rod, a first rotating column, a first rotating column, a first end face gear, a second fixed rod, a second rotating column, a second end face gear and a second screen are provided. When the inner column rotates clockwise, the bevel gear is driven to rotate clockwise. At this time, the bevel gear drives the first end face gear and the second end face gear to rotate clockwise and counterclockwise respectively. At this time, the first end face gear drives the first rotating column to rotate inside the first fixed rod, and the first screen will rotate clockwise accordingly. The second end face gear drives the second rotating column to rotate inside the second fixed rod, and the second screen will rotate counterclockwise accordingly. The Chinese medicinal materials will be preliminarily screened in the first screen, and the preliminarily screened Chinese medicinal materials will fall into the second screen. At this time, the second screen will screen the Chinese medicinal materials again while rotating, and the screened Chinese medicinal materials will fall to the bottom of the processing box and be collected by the collection box. The equipment uses the driving motor as a single power source to drive the first gear to rotate clockwise, and then through the sequential linkage of the gear timing belt, inner column and other components, the power is accurately transmitted to the first end face gear and the second end face gear of the screening component, and then the first screen and the second screen are driven to rotate. This coherent power transmission mechanism caused by a single power source ensures the stability of the power output of the entire screening process; In the present invention, a bevel gear, a first screen, a first end gear, a second end gear and a second screen are provided. When the bevel gear drives the first end gear and the second end gear to rotate, and the first screen and the second screen are respectively rotated clockwise and counterclockwise, the relative rotation design greatly improves the screening effect. An efficient screening space is formed between the two relatively rotating components. The Chinese medicinal materials are subjected to forces in different directions between the two components. On the one hand, the relative motion can make the Chinese medicinal materials fully roll and disperse in the screening area, and avoid the Chinese medicinal materials from gathering together and affecting the screening accuracy. On the other hand, the forces in different directions can screen the Chinese medicinal materials from multiple angles, and more effectively separate the Chinese medicinal materials that do not meet the specific particle size requirements. Compared with the screening method of rotating in a single direction, the screening efficiency and accuracy are greatly improved. In the present invention, by providing a first screen, a first retaining ring, a second screen and a second retaining ring, when the first screen and the second screen are rotating, the first retaining ring and the second retaining ring will shield the Chinese medicinal materials. Through the design of the first retaining ring and the second retaining ring, the Chinese medicinal materials will not fly out during screening, thereby avoiding the situation where some materials fail to be effectively screened due to accidental flying out, thereby ensuring that all Chinese medicinal materials entering the screening link can be fully screened, improving the screening quality, and making the particle size of the Chinese medicinal materials finally collected more uniform and consistent; In the present invention, by providing a first limiting sponge strip, a first crushing roller, a second crushing roller and a second limiting sponge strip, through the design of two groups of first limiting sponge strips and second limiting sponge strips, during the operation process, they can be combined with the first crushing roller and the second crushing roller to form a loading space, so that the Chinese medicinal materials will not fly out during the crushing process, reducing the possibility of equipment damage due to materials entering other equipment, reducing the maintenance cost and downtime of the equipment, and ensuring the continuity of production operations.

Through the design of two groups of first limiting sponge strips 17 and second limiting sponge strips 54, a feeding space can be formed in combination with the first crushing roller 24 and the second crushing roller 28 during operation, so that the Chinese medicinal materials will not fly out during the crushing process, reducing the possibility of equipment damage caused by materials entering other equipment, reducing the maintenance cost and downtime of the equipment, and ensuring the continuity of production operations; An inner column 35 is rotatably installed in the inner wall of the processing box 11, and a second gear 36 is fixedly installed on the inner column 35. A gear timing belt 37 is installed on the second gear 36 and the first gear 26. A bevel gear 38 is fixedly installed on the side wall of the inner column 35. A first fixed rod 41 is fixedly installed in the inner wall of the processing box 11, and a first rotating column 42 is rotatably installed on the first fixed rod 41. A first screen 43 is fixedly installed on the upper end of the first rotating column 42 by bolts. When in use, the drive motor 22 can be started first. Under the action of the drive motor 22, the first rotating shaft 23, the first crushing roller 24, the half gear 25 and the first gear 26 will be driven to rotate clockwise. At this time, the first crushing roller 24 will drive the second crushing roller 28 meshing therewith to rotate counterclockwise, and then the Chinese medicinal materials will be put into the collecting cover 19. At this time, the Chinese medicinal materials will slide downward along the inclined feeding plate 31 and fall between the first crushing roller 24 and the second crushing roller 28. At this time, the Chinese medicinal materials will be The first crushing roller 24 and the second crushing roller 28 are crushed, and the crushed Chinese medicinal materials will fall into the first screen 43 through the discharge port 16. The rotation of the two half gears 25 will drive the two racks 32 meshing with them to slide to the left. At this time, the two racks 32 will drive the loading plate 31 to slide outward in the chute 18. At this time, the loading plate 31 will drive the fixed bar 33 fixed to it to move accordingly, and the fixed bar 33 will squeeze the two springs 34 to compress them. When the two half gears 25 rotate to a state of misalignment with the racks 32, the two springs 34 restore their elastic potential energy to drive the fixed bar 33 and the loading plate 31 to reset. Therefore, when the equipment is operating, the loading plate 31 can slide back and forth in the chute 18. This reciprocating motion can not only continuously transport the Chinese medicinal materials, but also impact and evacuate the possible accumulation area of ​​Chinese medicinal materials during the resetting process. If a small amount of Chinese medicinal materials are locally accumulated inside the equipment, the loading plate 31 The reset movement will break up the gathered Chinese medicinal materials and return them to the normal flow path of Chinese medicinal materials, thus effectively preventing the blockage caused by the accumulation of Chinese medicinal materials and ensuring the long-term stable operation of the equipment; A first retaining ring 44 is fixedly installed on the upper end of the first screen 43 by bolts, a first end face gear 45 is fixedly sleeved on the first rotating column 42, a second fixed rod 46 is fixedly installed in the inner wall of the processing box 11, a second rotating column 47 is rotatably installed inside the second fixed rod 46, a second end face gear 48 is fixedly installed on the lower end of the second rotating column 47, the second end face gear 48 and the first end face gear 45 are both meshed with the bevel gear 38, a second screen 49 is fixedly installed on the upper end of the second rotating column 47 by bolts, the second screen 49 is opposite to the feed opening 16, when it is necessary to take the screened Chinese medicinal materials, the collecting box 13 can be pulled out of the slot 12 at this time, and then the processing box 11 is opened, and the second retaining ring 51 and the first retaining ring 44 are respectively connected by the second screen 49 and The first screen 43 is disassembled, and then the Chinese medicinal materials can be taken out. The second retaining ring 51 is fixedly installed on the upper end of the second screen 49 by bolts. When the equipment is in operation, the first gear 26 will also rotate clockwise with the drive of the drive motor 22. Under the rotation of the first gear 26, the inner column 35 will be driven to rotate clockwise through the gear timing belt 37. Under the clockwise rotation of the inner column 35, the bevel gear 38 will be driven to rotate clockwise. At this time, the bevel gear 38 drives the first end face gear 45 and the second end face gear 48 to keep rotating clockwise and counterclockwise respectively. At this time, the first end face gear 45 will drive the first rotating column 42 to rotate inside the first fixed rod 41, and the first screen 43 will rotate clockwise accordingly, and the second end face gear 48 will drive the second rotating column 47 inside the second fixed rod 46 The Chinese medicinal materials will be preliminarily screened in the first screen 43, and the preliminarily screened Chinese medicinal materials will fall into the second screen 49. At this time, the second screen 49 will screen the Chinese medicinal materials again while rotating, and the screened Chinese medicinal materials will fall to the bottom of the processing box 11 and be collected by the collecting box 13. The equipment uses the driving motor 22 as a single power source to drive the first gear 26 to rotate clockwise, and then through the sequential linkage of the gear timing belt 37, the inner column 35 and other components, the power is accurately transmitted to the first end face gear 45 and the second end face gear 48 of the screening component, and then the first screen 43 and the second screen 49 are driven to rotate. This coherent power transmission mechanism caused by a single power source ensures the stability of the power output of the entire screening process. Qualitative; when the bevel gear 38 drives the first end face gear 45 and the second end face gear 48 to rotate, and the first screen 43 and the second screen 49 keep rotating clockwise and counterclockwise respectively, this relative rotation design greatly improves the screening effect, and an efficient screening space is formed between the two relatively rotating parts. The Chinese medicinal materials are subjected to forces in different directions between the two. On the one hand, this relative movement can make the Chinese medicinal materials fully roll and disperse in the screening area to avoid the Chinese medicinal materials from gathering together and affecting the screening accuracy; on the other hand, the forces in different directions can screen the Chinese medicinal materials from multiple angles, and more effectively separate the Chinese medicinal materials that do not meet the specific particle size requirements. Compared with the screening method of rotating in a single direction, the screening efficiency and accuracy are greatly improved;When the first screen 43 and the second screen 49 are rotating, the first baffle ring 44 and the second baffle ring 51 will block the Chinese medicinal materials. Through the design of the first baffle ring 44 and the second baffle ring 51, the Chinese medicinal materials will not fly out during screening, avoiding the situation where some materials fail to be effectively screened due to accidental flying out, thereby ensuring that all Chinese medicinal materials entering the screening link can be fully screened, improving the screening quality, and making the particle size of the Chinese medicinal materials finally collected more uniform. ;

[0020] Working principle: In the first step, the driving motor 22 can be started when in use. Under the action of the driving motor 22, the first rotating shaft 23, the first crushing roller 24, the half gear 25 and the first gear 26 will be driven to rotate clockwise. At this time, the first crushing roller 24 will drive the second crushing roller 28 meshing therewith to rotate counterclockwise, and then the Chinese medicinal materials will be put into the collecting cover 19. At this time, the Chinese medicinal materials will slide downward along the inclined feeding plate 31 and fall between the first crushing roller 24 and the second crushing roller 28. At this time, the Chinese medicinal materials will be crushed by the first crushing roller 24 and the second crushing roller 28. The crushed Chinese medicinal materials will fall into the first screen 43 through the discharge port 16. The rotation of the two half gears 25 will drive the two racks 32 meshing therewith. When the gears 35 are moved to the left, the two racks 32 will drive the loading plate 31 to slide outward inside the chute 18. At this time, the loading plate 31 will drive the fixed bar 33 fixed thereto to move accordingly. The fixed bar 33 will squeeze the two springs 34 to compress them. When the two half gears 25 rotate to a misaligned state with the racks 32, the two springs 34 will restore their elastic potential energy to drive the fixed bar 33 and the loading plate 31 to reset. Therefore, when the equipment is operating, the loading plate 31 can slide back and forth inside the chute 18. This reciprocating motion can not only continuously transport Chinese medicinal materials, but also impact and evacuate the possible accumulation area of ​​Chinese medicinal materials during the resetting process. If a small amount of Chinese medicinal materials are locally accumulated inside the equipment, the resetting motion of the loading plate 31 will break up these accumulated Chinese medicinal materials and return them to the normal flow path of Chinese medicinal materials, thereby effectively preventing the blockage caused by the accumulation of Chinese medicinal materials and ensuring the long-term stable operation of the equipment. In the second step, when the equipment is in operation, the first gear 26 will also rotate clockwise with the drive of the drive motor 22. The rotation of the first gear 26 will drive the inner column 35 to rotate clockwise through the gear timing belt 37. The clockwise rotation of the inner column 35 will drive the bevel gear 38 to rotate clockwise. At this time, the bevel gear 38 drives the first end face gear 45 and the second end face gear 48 to keep rotating clockwise and counterclockwise respectively. At this time, the first end face gear 45 will drive the first rotating column 42 to rotate inside the first fixed rod 41, and the first screen 43 will rotate clockwise accordingly. The second end face gear 48 will drive the second rotating column 47 to rotate inside the second fixed rod 46, and the second screen 49 will rotate counterclockwise accordingly. At this time, the second end face gear 48 will drive the second rotating column 47 to rotate inside the second fixed rod 46, and the second screen 49 will rotate counterclockwise accordingly. The medicinal materials will be preliminarily screened in the first screen 43, and the preliminarily screened Chinese medicinal materials will fall into the second screen 49. At this time, the second screen 49 will screen the Chinese medicinal materials again when rotating. The screened Chinese medicinal materials will fall to the bottom of the processing box 11 and be collected by the collection box 13. The equipment uses the driving motor 22 as a single power source to drive the first gear 26 to rotate clockwise, and then through the sequential linkage of the gear timing belt 37, the inner column 35 and other components, the power is accurately transmitted to the first end face gear 45 and the second end face gear 48 of the screening component, and then the first screen 43 and the second screen 49 are driven to rotate. This coherent power transmission mechanism caused by a single power source ensures the stability of the power output of the entire screening process; In the third step, when the bevel gear 38 drives the first end face gear 45 and the second end face gear 48 to rotate, and the first screen 43 and the second screen 49 keep rotating clockwise and counterclockwise respectively, this relative rotation design greatly improves the screening effect, and an efficient screening space is formed between the two relatively rotating parts. The Chinese medicinal materials are subjected to forces in different directions between the two. On the one hand, this relative movement can make the Chinese medicinal materials fully roll and disperse in the screening area to avoid the Chinese medicinal materials from gathering together and affecting the screening accuracy; on the other hand, the forces in different directions can screen the Chinese medicinal materials from multiple angles, and more effectively separate the Chinese medicinal materials that do not meet the specific particle size requirements. Compared with the screening method of rotating in a single direction, the screening efficiency and accuracy are greatly improved; Step 4: When the first screen 43 and the second screen 49 are rotating, the first retaining ring 44 and the second retaining ring 51 will shield the Chinese medicinal materials. The design of the first retaining ring 44 and the second retaining ring 51 prevents the Chinese medicinal materials from flying out during screening, thereby avoiding the situation where some materials fail to be effectively screened due to accidental flying out, thereby ensuring that all Chinese medicinal materials entering the screening process can be fully screened, improving the screening quality, and making the particle size of the Chinese medicinal materials finally collected more uniform and consistent; The fifth step is to design two groups of first limiting sponge strips 17 and second limiting sponge strips 54, which can be combined with the first crushing roller 24 and the second crushing roller 28 to form a loading space during operation, so that the Chinese medicinal materials will not fly out during the crushing process, reducing the possibility of equipment damage due to materials entering other equipment, reducing equipment maintenance costs and downtime, and ensuring the continuity of production operations.
