Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine decoction piece processing technology, specifically to a screening and impurity removal device for processing traditional Chinese medicine decoction pieces. Background Technology

[0002] Prepared medicinal herbs are products made from raw medicinal materials through processing, slicing, and drying. This process reduces the moisture and microorganisms in the herbs, prevents mold and insect infestation, and extends their shelf life. They can be directly used in clinical dispensing or pharmaceutical production in traditional Chinese medicine. After processing, prepared medicinal herbs are smaller in size, making them easier to store, more flexible in use, and more stable in medicinal properties. They serve as an important carrier for TCM diagnosis and treatment. After drying, prepared medicinal herbs need to be sieved to remove impurities and debris adhering to their surface, thus ensuring the purity of the medicinal materials.

[0003] In existing technologies, Chinese medicinal herbs are mainly screened to remove impurities and debris using vibrating screening equipment. However, because the surface of dried Chinese medicinal herbs is uneven and easily attracts fine dust particles, vibrating screening equipment struggles to thoroughly clean them, resulting in low impurity removal efficiency and often requiring repeated screening.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this screening and impurity removal equipment for processing Chinese herbal medicine slices, when the two soft-bristled brush rollers on the hopper rotate, the flexible friction of the bristles and the penetration through the gaps effectively remove dust particles attached to the surface of the Chinese herbal medicine slices, thus avoiding damage to the slices. A comb plate can be inserted into the soft-bristled brush rollers so that the internal impurities can be combed out in time when the brush rollers rotate, improving the dust removal effect. The rectangular discharge port opened on the V-shaped discharge plate allows the Chinese herbal medicine slices in the hopper to fall between the two soft-bristled brush rollers for dust particle cleaning. The opening and closing of the rectangular discharge port can be controlled by adjusting the components and the blocking plate to prevent the Chinese herbal medicine slices from accumulating between the two soft-bristled brush rollers during the initial feeding of the hopper, which would affect the cleaning effect. The dust collection hood can be connected to a dust collection device to remove the dust generated by the soft-bristled brush rollers during operation in time, reducing the amount of dust in the hopper.

[0018] After cleaning, the Chinese herbal medicine slices can fall directly onto the screening plate of the vibrating frame. Through the cooperation of the support base, support plate, insert column and vibrating motor, the Chinese herbal medicine slices on the screening plate are vibrated and screened. On the one hand, large impurities and debris are separated from the Chinese herbal medicine slices, improving the efficiency of screening and impurity removal. On the other hand, vibration can further separate the dust particles remaining on the Chinese herbal medicine slices. The soft brush roller combined with the vibrating screening plate can greatly improve the cleaning efficiency and reduce manual intervention.

[0019] 2. In this screening and impurity removal equipment for processing Chinese herbal medicine slices, several triangular scrapers set on the screening plate can scrape off the residue on the screen surface, keeping the screen holes unobstructed, thereby maintaining stable screening efficiency and accuracy. At the same time, the triangular scrapers can prolong the residence time of Chinese herbal medicine slices on the screening plate, improve the screening effect, and reduce the number of screenings. The scraper support can move back and forth on the triangular scraper, which is conducive to breaking up the Chinese herbal medicine slices piled on the screening plate, making them evenly distributed, and further improving the screening effect. The triangular scraper can move horizontally along the vibrating frame through the second sliding support. The L-shaped connecting frame fixed on the second sliding support can abut against the second abutting support on the first electric push rod, making it easy to adjust the working position of the triangular scraper when the screening plate is working. Through the cooperation of several arc-shaped abutting blocks and abutting rods fixed on the vibrating frame, the triangular scraper drives the scraper support to reciprocate during the movement.

[0020] The cleaning tooth plate can clean impurities in the gaps between the teeth of the comb plate, improving the cleaning effect of the comb plate on the soft brush roller. When the L-shaped connecting frame moves horizontally due to resistance, the L-shaped contact strip can be made to contact the contact wedge on the C-shaped bracket. This allows the C-shaped bracket to drive the triangular contact block to first contact the L-shaped contact block on the comb plate, causing the comb plate to automatically retract. This allows the cleaning tooth plate to comb out the impurities in the gaps between the teeth. When the triangular contact block continues to move, it can contact the tooth strip, causing the cleaning tooth plate to automatically deflect. This helps to push the impurities in the comb plate downwards, improving the impurity separation effect.

[0021] 3. In this screening and impurity removal equipment for processing Chinese herbal medicine slices, the cooperation of the guide hollow rod, slide rod and seventh spring on the triangular scraper facilitates the automatic insertion of the conical brush head when it encounters the sieve holes of the screening plate, which is beneficial for clearing blockages and improving the screening effect of impurities. The third contact support fixed on the contact rod can move back and forth synchronously with the contact rod, so that the third contact support and the contact plate on the guide hollow rod can reciprocate to achieve the purpose of reciprocating contact, which enables the conical brush head to rotate during use and improves the efficiency of clearing blockages.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1 to 10 A screening and impurity removal device for processing Chinese herbal medicine slices includes a base plate 1, a mounting frame 2 fixed on the base plate 1, a hopper 3 fixed on the mounting frame 2, two soft brush rollers 4 rotatably connected to the hopper 3, and a movable comb plate 5 is provided on one side of each of the two soft brush rollers 4, and a cleaning plate 6 is inserted into the comb plate 5. A dust suction hood 7 and a first electric push rod 24 are fixed on the hopper 3 respectively.

[0035] Below the hopper 3 is an inclined vibrating frame 8, on which a screening plate 9 is installed. Several movable triangular scrapers 12 are provided on the screening plate 9, and movable scraper supports 10 are provided on the triangular scrapers 12.

[0036] Two support seats 13 are fixed on the base plate 1, two support plates 14 are fixed on the mounting frame 2, and several insert columns 15 are fixed on the vibration frame 8. The several insert columns 15 are elastically connected to the two support seats 13 and the two support plates 14 respectively through the first spring 16. A vibration motor 17 is fixed on the vibration frame 8, and a collection box 18 is provided on the base plate 1.

[0037] A V-shaped feeding plate 19 is fixed inside the hopper 3. A rectangular feeding port 20 is opened on the V-shaped feeding plate 19. A blocking plate 21 is provided below the rectangular feeding port 20. A first sliding bracket 22 is fixed on both sides of the V-shaped feeding plate 19. A sliding block 28 is fixed at both ends of the blocking plate 21. The sliding block 28 is slidably connected to the first sliding bracket 22. An adjustment component for driving the blocking plate 21 to move is provided on the hopper 3.

[0038] Two soft brush rollers 4 are each fixed with a toothed disc 25 at one end. The two toothed discs 25 mesh with each other. A connecting plate 26 is fixed on the mounting bracket 2. A servo motor 27 is fixed on the connecting plate 26. The motor shaft of the servo motor 27 is fixedly connected to one end of one of the soft brush rollers 4.

[0039] The adjustment assembly includes a first abutment bracket 211, which is slidably connected to the hopper 3. One end of the first abutment bracket 211 abuts against one of the sliding blocks 28. A second spring 212 is connected between the sliding block 28 and the first sliding bracket 22. An abutment block 213 is provided on one side of the first abutment bracket 211. The abutment block 213 is elastically connected to the piston rod of the first electric push rod 24 through a third spring 214.

[0040] refer to Figures 1 to 5The dried Chinese herbal medicine slices are fed into the hopper 3 and fall onto the V-shaped feed plate 19. The motor shaft of the servo motor 27 drives one of the soft-bristle brush rollers 4 to rotate. With the cooperation of two meshing toothed discs 25, the two soft-bristle brush rollers 4 rotate synchronously and in opposite directions. The piston rod of the first electric push rod 24 drives the elastically connected abutment block 213 to move down and abut against the first abutment bracket 211, so that the first abutment bracket 211 slides on the hopper 3. This achieves the purpose of automatic abutment between the first abutment bracket 211 and the sliding block 28, so that the blocking plate 21 slides on the first sliding bracket 22 installed on the V-shaped feed plate 19, thereby automatically opening the rectangular feed port 20, allowing the Chinese herbal medicine slices to fall between the two rotating soft-bristle brush rollers 4. Through the flexible friction of the bristles and the penetration of the gaps, the dust particles attached to the surface of the Chinese herbal medicine slices are effectively removed. The dust particles are removed from the hopper 3 to avoid damaging the Chinese herbal medicine pieces. The dust hood 7 installed on the hopper 3 is connected to the dust collection equipment to remove the dust particles floating in the hopper 3. Then, the cleaned Chinese herbal medicine pieces fall from the bottom of the hopper 3 onto the inclined screening plate 9. The screening plate 9 vibrates with the cooperation of the vibrating frame 8, the vibrating motor 17, the insert column 15, the support plate 14 and the support seat 13. On the one hand, large impurities and debris are separated from the Chinese herbal medicine pieces, improving the efficiency of screening and impurity removal. On the other hand, the vibration can further separate the dust particles remaining on the Chinese herbal medicine pieces. The soft brush roller 4 is combined with the vibrating screening plate 9 to greatly improve the cleaning efficiency and reduce manual intervention, so that the dust particles and impurities fall into the collection box 18 on the bottom plate 1 for collection. The screened Chinese herbal medicine pieces are affected by the vibration and move downward along the inclined screening plate 9.

[0041] The hopper 3 has comb plates 5 on both sides, which are inserted into the soft brush roller 4. During the rotation of the soft brush roller 4, the impurities attached to it can be combed out in time, which improves the dust removal effect of Chinese herbal medicine pieces. Secondly, a connected collection box is installed at the bottom of the hopper 3 to facilitate the collection of impurities combed out by the soft brush roller 4. The bottom of the hopper 3 is equipped with a baffle to prevent Chinese herbal medicine pieces from falling into the collection box.

[0042] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 10 The comb plate 5 is elastically connected to the hopper 3 via the fourth spring 29, and an L-shaped abutment block 30 is fixed on the comb plate 5. A triangular abutment block 31 abuts on the L-shaped abutment block 30. An i-shaped bracket 32 ​​is connected to the triangular abutment block 31. A limit slide rod 33 is fixed on the hopper 3. The i-shaped bracket 32 ​​is slidably connected to the limit slide rod 33. An abutment wedge block 36 is fixed on the i-shaped bracket 32. One end of the cleaning plate 6 is rotatably connected to the hopper 3 via a torsion spring 61. A gear 34 is fixed on one end of the cleaning plate 6. The gear 34 meshes with a rack 35. The rack 35 is slidably connected to the hopper 3.

[0043] Both ends of the triangular scraper 12 are fixed with second sliding brackets 23. The second sliding brackets 23 are slidably connected to the vibration frame 8, and an L-shaped connecting bracket 37 is connected to the second sliding bracket 23. A fifth spring 38 is connected between the L-shaped connecting bracket 37 and the vibration frame 8. An L-shaped abutment strip 39 is fixed on the L-shaped connecting bracket 37. The lower end of the first electric push rod 24 is fixed with a second abutment bracket 40.

[0044] The side wall of the vibration frame 8 is provided with several equally spaced arc-shaped contact blocks 11, and one end of the scraper bracket 10 is fixed with a contact rod 41. The contact rod 41 is elastically connected to the second sliding bracket 23 through the sixth spring 42.

[0045] Several hollow guide rods 43 are rotatably connected to the triangular scraper 12. A sliding rod 44 is slidably connected to the hollow guide rod 43. A seventh spring 45 is connected between the sliding rod 44 and the hollow guide rod 43. A conical brush head 46 is fixed to the lower end of the sliding rod 44. An abutting piece 47 is fixed to the hollow guide rod 43. A third abutting bracket 48 is abutted on the abutting piece 47. The third abutting bracket 48 is slidably connected to the triangular scraper 12. One end of the third abutting bracket 48 is fixedly connected to the abutting rod 41.

[0046] refer to Figures 1 to 10 To improve the sieving effect of Chinese herbal medicine slices and reduce the number of sieving times, the piston rod of the first electric push rod 24 continues to extend downward, driving the second contact bracket 40 to move downward. At this time, the contact block 213 and the first contact bracket 211 remain in contact. The contact block 213 slides on the piston rod of the first electric push rod 24, and the third spring 214 stores force, which can achieve the purpose of the second contact bracket 40 contacting the L-shaped connecting frame 37. This causes the L-shaped connecting frame 37 to drive several second sliding brackets 23 to move horizontally on the vibrating frame 8, so that several triangular scrapers 12 can move on the sieve plate 9. The triangular scrapers 12 can scrape off the residue on the surface of the sieve. To maintain unobstructed sieve holes and thus ensure stable sieve efficiency and accuracy, the sieve plate 9 can be extended to improve the sieve effect and reduce the number of sieve operations. During the movement of the triangular scraper 12, the contact rod 41 can intermittently contact several arc-shaped contact blocks 11 on the side wall of the vibrating frame 8, so that the contact rod 41 can reciprocate on the second sliding support 23. The sixth spring 42 continuously stores and releases its elasticity so that the scraper support 10 can reciprocate on the triangular scraper 12, which helps to disperse the Chinese herbal medicine pieces piled on the sieve plate 9, making them evenly distributed, reducing accumulation, and further improving the sieve effect.

[0047] In addition, through the cooperation of the guide hollow rod 43, slide rod 44 and seventh spring 45 on the triangular scraper 12, the conical brush head 46 automatically inserts when it encounters the screen hole of the screening plate 9, which is conducive to clearing blockages and improving the screening effect of impurities. When the abutting rod 41 moves, it can drive the third abutting bracket 48 to move synchronously, so that the third abutting bracket 48 and the abutting piece 47 on the guide hollow rod 43 reciprocate to abut against each other. When the guide hollow rod 43 rotates, it can drive the conical brush head 46 to rotate synchronously, so that the conical brush head 46 can rotate in the screen hole, which can improve the efficiency of clearing blockages.

[0048] During the movement of the L-shaped connecting frame 37, the L-shaped abutment strip 39 can move synchronously, so that the L-shaped abutment strip 39 can automatically abut against the abutment wedge block 36. This causes the C-shaped bracket 32 ​​to drive the triangular abutment block 31 to slide on the limiting slide bar 33, so that the triangular abutment block 31 first abuts against the L-shaped abutment block 30, which can achieve the purpose of automatically retracting the comb plate 5 and separating it from the soft brush roller 4. The fourth spring 29 stores power, and then the triangular abutment block 31 continues to move and abut against the rack 35, causing the cleaning plate 6 to deflect on the hopper 3. The torsion spring 61 stores power, which can achieve the purpose of automatically pushing the impurities attached to the comb plate 5 downwards so that the impurities fall into the collection box, thereby improving the separation effect between the comb plate 5 and the impurities.

[0049] Example 3 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 10 This application also provides an adjustment component technical solution, the adjustment component includes a second electric push rod 215, the second electric push rod 215 is fixed on the hopper 3, and an L-shaped connecting block 216 is fixed on the output end of the second electric push rod 215, the L-shaped connecting block 216 is fixedly connected to the blocking plate 21.

[0050] refer to Figure 3 When the piston rod of the second electric push rod 215 retracts, it drives the blocking plate 21 to slide on the first sliding bracket 22 through the L-shaped connecting block 216, so as to automatically open the rectangular discharge port 20 and adjust the size of the opening so that the Chinese medicine slices fall between the two rotating soft brush rollers 4 for dust removal.

[0051] The vibration motor 17, the second electric push rod 215, the first electric push rod 24, and the servo motor 27 are all electrically connected to the controller via wires.
