Description

Technical Field

[0001] The invention relates to the technical field of Chinese herbal medicine slice production, and in particular to a Chinese herbal medicine slice classification and feeding device. Background Art

[0002] Chinese herbal medicine slices are processed and can be directly used in TCM clinics or preparations. Chinese herbal medicine slices can be classified in many ways. The following are common classification methods and their specific categories:

[0003] 1. Classify according to medicinal parts, such as rhizomes, stems, barks, leaves and flowers;

[0004] 2. Classify according to the processing method, such as processed pieces, water-processed pieces and fire-processed pieces;

[0005] 3. Classify by efficacy, such as antipyretic drugs, heat-clearing drugs, laxatives and anti-rheumatic drugs, etc.

[0006] For flower slices, since flower slices are usually crisp and tender, during the production and transportation process, the petals and stamens of the flower slices will fall off due to impact or friction, so the flower slices finally collected will contain a lot of debris. The debris will not only affect the quality of the final flower slice packaging, but also affect the weighing of the flower slices before packaging. Therefore, the debris needs to be screened out before the flower slices are packaged. Traditional screening methods mostly use high-frequency vibrating screens to screen Chinese herbal medicine slices. Since flower slices are relatively fragile, they will be squeezed against each other or collide with the screen due to high-frequency vibration during screening, causing some tiny stamens and petals to fall off, thereby affecting the screening efficiency and causing loss of output.

[0007] Therefore, it is necessary to provide a Chinese herbal medicine classification and loading device to solve the above problems. Summary of the Invention

In addition, during the screening process of the flower pieces, the flower pieces are not subjected to high-intensity vibration. Therefore, the device can promote the separation of crushed materials and whole materials under the premise of reducing damage to the flower pieces, thereby improving the separation efficiency.

[0020] Secondly, when the flower pieces are screened, some small flower pieces will be stuck in the strip grooves. In order to prevent a large number of flower pieces from blocking the strip grooves, the slide will drive a number of cuttings to move in the corresponding strip grooves during the reciprocating swing of the swing box, so that the flower pieces stuck in the strip grooves are brought to the supporting plate through the cuttings, and before the slide stops moving, the top block provided under the cuttings will push the flower pieces stuck in the strip grooves out, thereby effectively preventing a large number of flower pieces from blocking the strip grooves.

[0021] Third, when the end of the swing box with the whole material outlet tilts downward, the flower pieces will slide toward the supporting plate. At this time, the lifting frame located under the supporting plate will rise, and the lifting frame will drive several top bars to pass through the supporting plate. Then, the top bars that are pushed upward will disperse the flower pieces accumulated on the supporting plate, and finally cause the broken materials between the whole flower pieces to fall.

[0042] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] refer to Figures 1 to 19 The device for classifying and loading Chinese herbal medicine slices shown in the figure comprises a long swing box 1, the top of which is an open structure (such as Figure 13 As shown), one end of the swing box 1 is provided with a whole material outlet 2, a rotating baffle 3 is provided on the whole material outlet 2, and the bottom of the swing box 1 is provided with a crushed material outlet 4 (as shown Figure 7 As shown), the crushed material outlet 4 and the whole material outlet 2 are spaced apart along the length direction of the swing box 1, and the crushed material outlet 4 divides the bottom of the swing box 1 into a short plate 5 and a long plate 6 (as shown). Figure 13As shown in FIG, a plurality of strip-shaped through slots 7 are provided at one end of the long plate 6 near the crushed material outlet 4 and are evenly spaced along the width direction of the swing box 1. A support plate 8 is provided at one end of the long plate 6 near the whole material outlet 2. An anti-stuck slot slide is provided in the swing box 1. The anti-stuck slot slide includes a slide 9 and a plurality of inserts 10. The slide 9 slides along the length direction of the swing box 1. Two sets of symmetrical limiters are provided between the slide 9 and the swing box 1. The plurality of inserts 10 are evenly spaced along the width direction of the swing box 1. Each insert 10 They are all connected to the slide 9, and each insertion strip 10 is vertically inserted into the corresponding strip-shaped through groove 7. A top block 11 is slidably provided on each insertion strip 10. The bottom of the supporting plate 8 is provided with a lifting drive member for synchronously driving several top blocks 11 to rise. A fixed baffle 12 is provided on the side of the crushed material outlet 4. A material guide box 13 is provided at the bottom of the swing box 1. The top of the material guide box 13 is an open structure. The end of the material guide box 13 close to the supporting plate 8 is a closed structure. The other end of the material guide box 13 is provided with a discharge port 14.

[0044] The present invention is used for classifying and screening flower pieces. The specific screening process is as follows: the flower pieces are poured into the swing box 1, and the flower pieces are supported by the long plate 6 at the bottom of the swing box 1. At this time, the broken pieces in the flower pieces will leak out from the strip groove 7, while the whole piece of flower pieces cannot fall. The broken pieces will fall into the guide box 13 after falling from the strip groove 7, and finally be discharged from the discharge port 14. In order to promote the discharge of the broken pieces in the whole piece of flower pieces, the swing box 1 will be swung back and forth slowly during screening. When the swing box 1 is processed, the outer walls of both sides of the swing box 1 are connected with axially horizontal rotating shafts 56. In actual use, the sides of the swing box 1 are A driving device (not shown in the figure) is provided on the side for driving the rotating shaft 56 to rotate back and forth. The reciprocating rotation of the rotating shaft 56 causes the swing box 1 to swing back and forth like a seesaw. In the process of the swing box 1 swinging back and forth, the flower pieces will move back and forth on the long board 6 along the length direction of the swing box 1. When the end of the swing box 1 provided with the whole material outlet 2 is tilted downward, the flower pieces will slide from the end of the long board 6 close to the crushed material outlet 4 to the material supporting plate 8. In this process, the crushed materials in the flower pieces will fall into the material guide box 13 through the strip groove 7. At the same time, the slide 9 will move toward the whole material outlet 2 by itself due to gravity. When the slide 9 moves horizontally, it will move horizontally with the slide 9 When the slide 9 is stopped by one of the limit members, the lifting drive member drives the top block 11 on each cutting strip 10 to push the flower pieces stuck in the strip groove 7 upward. When one end of the swing box 1 with the crushed material outlet 4 tilts downward, the slide 9 will slide in the opposite direction from the whole material outlet 2 to the crushed material outlet 4. When the slide 9 moves in the opposite direction, the top block 11 drops, and at the same time, the flower pieces falling on the supporting plate 8 will slide toward the crushed material outlet 4. In this process, the crushed materials in the flower pieces will fall into the material guide box 13 through the strip groove 7. When the slide 9 is stopped by another limit member When a group of limit members stop, the flower slices will be blocked by several cuttings 10, and gaps 57 for the discharge of broken materials will be formed between adjacent cuttings 10. The whole piece of flower slices will not pass through the gap 57. The broken materials discharged from the gap 57 will be blocked by the fixed baffle 12 and eventually fall into the material guide box 13 from the broken material outlet 4. In summary, as the swing box 1 swings back and forth slowly, the broken materials in the flower slices will be screened out, and it is finally concluded that the flower slices are all whole materials. Then, when the screening is completed, the swing box 1 will swing to the whole material outlet 2 tilted downward, and the rotating baffle 3 will flip upward, so that the whole flower slices that fall on the supporting plate 8 will be discharged from the whole material outlet 2.

[0045] In order to show the specific installation method of the slide 9, the following features are set:

[0046] Both sides of the swing box 1 are fixed with guide rods 15, and the axial direction of each guide rod 15 is parallel to the length direction of the swing box 1. A counterweight block 16 (such as Figure 10 As shown), both ends of the slide 9 are formed with support rods 17 extended from the outside of the swing box 1, and each support rod 17 is fixed with a No. 1 guide sleeve 18, and each No. 1 guide sleeve 18 slides on the corresponding guide slide rod 15. Each set of limiters includes two buffer sleeves 19, and the two buffer sleeves 19 are respectively fixed on the two guide slide rods 15. The two buffer sleeves 19 on the same guide slide rod 15 are close to the fixed baffle 12 and the rotating baffle 3 respectively.

[0047] The slide 9 is made to slide along the length direction of the swing box 1 by means of a No. 1 guide sleeve 18 which is sleeved on the guide slide rod 15. When the swing box 1 swings back and forth, the slide 9 will slide from one end of the swing box 1 to the other end. During this process, the sliding stroke of the slide 9 is limited by two buffer sleeves 19 on each guide slide rod 15, and the inertial impact of the slide 9 is buffered by the buffer sleeve 19. The counterweight block 16 provided in the middle of the slide 9 is used to increase the weight of the slide 9, so that the slide 9 can slide downward by itself due to gravity.

[0048] In order to show the specific structure of the top block 11, the following features are set:

[0049] Each top block 11 is strip-shaped, and the length direction of each top block 11 is consistent with the length direction of the strip-shaped through groove 7. The top of each top block 11 is formed with a first arc surface 20 (such as Figure 19 As shown), each insert 10 has a first limiting rod 21 and a second limiting rod 22 formed at the bottom (as shown Figure 12 As shown), the first limiting rod 21 and the second limiting rod 22 are both vertical, each top block 11 is arranged below the bar-shaped through groove 7, and each top block 11 is located between the insert 10 and the support plate 8, and each insert 10 is formed with a second arc surface 23 on the side facing the top block 11, and one end of each top block 11 is formed with a vertical rod 24 (as shown). Figure 11 As shown), a support block 25 is formed on the vertical rod 24, and a No. 2 guide sleeve 26 is formed on the support block 25 and is sleeved on the No. 1 limit rod 21. The lower end of each No. 1 limit rod 21 is screwed with a limit nut 27 located below the No. 2 guide sleeve 26, and each No. 2 limit rod 22 passes downward through the corresponding support block 25.

[0050] When the cam 11 is in the downward position, the second guide sleeve 26 is restrained by the limit nut 27, thereby limiting the downward stroke of the second guide sleeve 26 and preventing the second guide sleeve 26 from sliding out of the first limit rod 21. When the cam 11 is in the downward position, the cam 11 is located below the corresponding strip groove 7, so that a part of the crushed materials falling through the strip groove 7 will fall from both sides along the No. 1 curved surface 20 at the top of the cam 11 and will not accumulate on the top of the cam 11. When the end of the swing box 1 with the whole material outlet 2 tilts downward, the slide 9 will drive several cam 11 to slide toward the material supporting plate 8. Before the slide 9 is limited by the corresponding buffer sleeve 19, several cam 11 will be synchronously driven up by the jacking drive member. Each top block 11 will be inserted upward into the corresponding strip groove 7, and will eventually push out the flower pieces stuck in the strip groove 7. When the top block 11 slides up and down, the vertical rod 24 passing through the support block 25 prevents the top block 11 from rotating, ensuring that the top block 11 can only slide in the vertical direction. When the end of the swing box 1 with the crushing outlet 4 tilts downward, the slide 9 will slide toward the crushing outlet 4. At the same time, the flower pieces on the supporting plate 8 will slide toward the slide 9. When the flower pieces slide toward the slide 9, the whole material of the flower pieces is prevented from being discharged from the crushing outlet 4 by the obstruction of several cuttings 10. At this time, the crushed materials will fall toward the crushing outlet 4 through the gap 57 between adjacent cuttings 10, and the No. 2 curved surface 23 on the cuttings 10 will cause the crushed materials to slide from both sides of the cuttings 10 to the gap 57, preventing the crushed materials from accumulating on the cuttings 10.

[0051] In order to show the specific structure of the jacking drive, the following features are set:

[0052] The lifting drive member is a contact frame 28 fixed to the bottom of the support plate 8 (such as Figure 9 As shown), the abutment frame 28 is located in the material guide box 13, and a first inclined surface 29 is provided at one end of the abutment frame 28 facing the crushed material outlet 4. The lower end of each upright 24 is formed with a first inclined wedge block 30 located in the material guide box 13, and a second inclined surface 31 is provided on the first inclined wedge block 30 to cooperate with the first inclined surface 29.

[0053] In the initial state, each top block 11 is in a descending state due to gravity, so the No. 1 inclined wedge 30 connected to the top block 11 through the vertical rod 24 is also in a descending state. When the No. 1 inclined wedge 30 is in a descending state, the No. 2 inclined surface 31 thereon corresponds to the No. 1 inclined surface 29. Then, in the process of the slide 9 sliding from the crushed material outlet 4 to the whole material outlet 2, the No. 1 inclined wedge 30 will gradually approach the abutment frame 28. Then, before the slide 9 is stopped by the corresponding buffer sleeve 19, the No. 1 inclined wedge 30 will conflict with the conflict frame 28. At this time, through the cooperation of the No. 1 inclined surface 29 and the No. 2 inclined surface 31, the No. 1 inclined wedge block 30 will drive the top block 11 to rise into the strip-shaped through groove 7. When the sliding frame 9 slides in the opposite direction, each No. 1 inclined wedge block 30 will separate from the conflict frame 28. In this way, when the swing box 1 swings from tilt to horizontal, each top block 11 will again drive the No. 1 inclined wedge block 30 to slide down by gravity, and finally the top block 11 and the No. 1 inclined wedge block 30 will be in a descending state again.

[0054] When the flower pieces are piled on the supporting plate 8, in order to promote the falling of the broken pieces in the flower pieces, the following features are set:

[0055] A lifting frame 32 (such as Figure 18 As shown), a plurality of evenly distributed top bars 33 are fixed on the top of the lifting frame 32, and the upper end of each top bar 33 vertically passes through the support plate 8, and the top of each top bar 33 is flush with the top of the support plate 8 (as shown). Figure 9 As shown), the bottom of the supporting plate 8 is formed with four fixed rods 34 distributed in a matrix, each fixed rod 34 is perpendicular to the supporting plate 8, and the upper end of each fixed rod 34 is fixedly connected to the supporting plate 8, and the lifting frame 32 is formed with four No. 3 guide sleeves 35 respectively mounted on the four fixed rods 34, and the lower end of each fixed rod 34 is screwed with a screw cap 36 located below the corresponding No. 3 guide sleeve 35, and the swing box 1 is provided with a lifting drive component for driving the lifting frame 32 to move up and down.

[0056] When the end of the swing box 1 with the crushed material outlet 4 tilts downward, the lifting frame 32 is in a descending state due to gravity. At this time, the four screw caps 36 are used to limit the descending stroke of the lifting frame 32 to prevent the No. 3 guide sleeve 35 from sliding out of the corresponding fixed rod 34. When the lifting frame 32 is in a descending state, the top of each top bar 33 is flush with the top of the supporting plate 8. When the end of the swing box 1 with the whole material outlet 2 tilts downward, the slide 9 will slide toward the whole material outlet 2. When the slide 9 is hit by the corresponding buffer sleeve 19 Before stopping, the lifting drive will drive the lifting frame 32 to rise, so that several top bars 33 on the lifting frame 32 will pass through the outside of the supporting plate 8, and the flower pieces that have fallen on the supporting plate 8 will be dispersed by the rising top bars 33, thereby promoting the falling of the fragments between the whole flower pieces, and further improving the efficiency of the fragment screening. When the swing box 1 swings in the opposite direction, the lifting frame 32 will drop again due to gravity, and finally the top of each top bar 33 will be flush with the top of the supporting plate 8 again.

[0057] In order to show the specific structure of the lifting drive, the following features are set:

[0058] The lifting drive member includes two sets of sliding resistance members respectively arranged on both sides of the swing box 1, each set of sliding resistance members includes a No. 4 guide sleeve 37, a No. 5 guide sleeve 38 and a strip rod 39, and each guide rod 15 is provided with a No. 3 limit rod 40 parallel to it below. Figure 4 As shown), one end of the No. 3 limit rod 40 is fixedly connected to the swing box 1 through the vertical connecting frame 41, and a limit block 42 is formed on the other end of the No. 3 limit rod 40. The No. 4 guide sleeve 37 is sleeved on the corresponding guide slide 15, and the No. 5 guide sleeve 38 is sleeved on the corresponding No. 3 limit rod 40. A spring 43 is sleeved on the No. 3 limit rod 40, and the two ends of the spring 43 respectively conflict with the No. 5 guide sleeve 38 and the vertical connecting frame 41. The No. 4 guide sleeve 37 and A No. 1 connecting plate 44 is provided between the No. 5 guide sliding sleeve 38 to connect the two. A No. 2 connecting plate 45 is formed on the No. 5 guide sliding sleeve 38. The strip rod 39 is fixedly connected to the No. 2 connecting plate 45, and the strip rod 39 is parallel to the guide sliding rod 15. No. 2 oblique wedge blocks 46 are fixed on both sides of the lifting frame 32. Each No. 2 oblique wedge block 46 is provided with a No. 3 inclined surface 47. One end of each strip rod 39 is provided with a No. 4 inclined surface 48 that is wedge-matched with the No. 3 inclined surface 47.

[0059] When the No. 4 guide sliding sleeve 37 is sleeved on the corresponding guide sliding rod 15, the No. 4 guide sliding sleeve 37 is located between the corresponding two buffer sleeves 19. When the end of the swing box 1 with the crushing outlet 4 tilts downward, the slide 9 slides toward the crushing outlet 4. At this time, each spring 43 releases its elastic force to drive the corresponding No. 5 guide sliding sleeve 38 to slide toward the corresponding limit block 42. The limit block 42 prevents the No. 5 guide sliding sleeve 38 from sliding out of the corresponding No. 3 limit rod 40. At the same time, the strip rod 39 connected to the No. 5 guide sliding sleeve 38 through the No. 2 connecting plate 45 is separated from the No. 2 oblique wedge block 46. When the end of the swing box 1 with the whole material outlet 2 tilts downward, the slide 9 slides toward the whole material outlet 2. During this process, it slides on the guide The No. 1 guide sleeve 18 on the slide bar 15 will translate toward the No. 4 guide sleeve 37. When the No. 1 guide sleeve 18 conflicts with the No. 4 guide sleeve 37, the No. 5 guide sleeve 38 will overcome the elastic force of the spring 43 and drive the strip rod 39 to slide toward the No. 2 oblique wedge 46 through the gravity drive of the counterweight block 16 on the slide 9. When one end of the strip rod 39 conflicts with the No. 2 oblique wedge 46, the two No. 2 oblique wedges 46 will synchronously drive the lifting frame 32 to rise through the cooperation of the No. 3 inclined surface 47 and the No. 4 inclined surface 48, so that the several top strips 33 on the lifting frame 32 pass through the supporting plate 8 upward, and the flower pieces accumulated on the supporting plate 8 are dispersed by the top strips 33 passing through the supporting plate 8.

[0060] In order to enable the flower pieces to slide smoothly onto the support plate 8, the following features are provided:

[0061] Several strip-shaped through grooves 7 divide one end of the long plate 6 into several long strips 49, and the top of each long strip 49 is formed with a third arc surface 50 (such as Figure 14 As shown), a guide ramp 51 is formed on one end of the support plate 8 facing the crushing outlet 4 (as shown Figure 9 shown).

[0062] The flower pieces falling into the swing box 1 will be supported by several long strips 49. The third curved surface 50 provided on the top of the long strips 49 will promote the crushed materials to slide into the strip grooves 7 on both sides of the long strips 49. In the process of the flower pieces sliding from the several long strips 49 to the supporting plate 8, the flower pieces can slide smoothly onto the supporting plate 8 through the guide ramp 51 provided at one end of the supporting plate 8.

[0063] In order to show how the rotating baffle 3 is turned over, the following features are set:

[0064] The upper end of the rotating baffle 3 is hingedly connected to the swing box 1. Push-pull shafts 52 are formed on both sides of the rotating baffle 3. Hydraulic cylinders 53 are provided on both sides of the swing box 1. The output end of the hydraulic cylinder 53 is rotatably connected to the push-pull shaft 52, and the other end of the hydraulic cylinder 53 is hingedly connected to the outer wall of the swing box 1.

[0065] The hydraulic cylinders 53 provided on both sides of the swing box 1 are used to synchronously drive the rotating baffle 3 to flip over. When the flower pieces are screened, the output ends of the two hydraulic cylinders 53 retract synchronously to drive the rotating baffle 3 to block the whole material outlet 2. After the flower pieces are screened, the output ends of the two hydraulic cylinders 53 extend synchronously to drive the rotating baffle 3 to flip upward, and finally open the whole material outlet 2.

[0066] In order to facilitate the discharge of the whole material of flower slices from the whole material outlet 2, the following features are set:

[0067] A plurality of nozzles 54 (such as Figure 17 As shown), each nozzle 54 faces the whole material outlet 2, and a dust cover 55 is fixed on the top of the swing box 1 to cover the top opening of the swing box 1.

[0068] After the flower pieces are screened, one end of the swing box 1 provided with the whole material outlet 2 will tilt downward. At the same time, the rotating baffle 3 will flip upward to open the whole material outlet 2, so that the flower pieces accumulated on the supporting plate 8 will be discharged from the whole material outlet 2. At this time, several nozzles 54 connected to the fixed baffle 12 will blow air toward the whole material outlet 2 to promote the discharge of the flower pieces from the whole material outlet 2.

[0069] Working principle:

[0070] The present invention is used for classifying and screening flower pieces. The specific screening process is as follows: the flower pieces are poured into the swing box 1, and the flower pieces are supported by the long plate 6 at the bottom of the swing box 1. At this time, the broken pieces in the flower pieces will leak out from the strip groove 7, while the whole piece of flower pieces cannot fall. The broken pieces will fall into the guide box 13 after falling from the strip groove 7, and finally be discharged from the discharge port 14. In order to promote the discharge of the broken pieces in the whole piece of flower pieces, the swing box 1 will be swung back and forth slowly during screening. When the swing box 1 is processed, the outer walls of both sides of the swing box 1 are connected with axially horizontal rotating shafts 56. In actual use, the sides of the swing box 1 are A driving device (not shown in the figure) is provided on the side for driving the rotating shaft 56 to rotate back and forth. The reciprocating rotation of the rotating shaft 56 causes the swing box 1 to swing back and forth like a seesaw. In the process of the swing box 1 swinging back and forth, the flower pieces will move back and forth on the long board 6 along the length direction of the swing box 1. When the end of the swing box 1 provided with the whole material outlet 2 is tilted downward, the flower pieces will slide from the end of the long board 6 close to the crushed material outlet 4 to the material supporting plate 8. In this process, the crushed materials in the flower pieces will fall into the material guide box 13 through the strip groove 7. At the same time, the slide 9 will move toward the whole material outlet 2 by itself due to gravity. When the slide 9 moves horizontally, it will move horizontally with the slide 9 When the slide 9 is stopped by one of the limit members, the lifting drive member drives the top block 11 on each cutting strip 10 to push the flower pieces stuck in the strip groove 7 upward. When one end of the swing box 1 with the crushed material outlet 4 tilts downward, the slide 9 will slide in the opposite direction from the whole material outlet 2 to the crushed material outlet 4. When the slide 9 moves in the opposite direction, the top block 11 drops, and at the same time, the flower pieces falling on the supporting plate 8 will slide toward the crushed material outlet 4. In this process, the crushed materials in the flower pieces will fall into the material guide box 13 through the strip groove 7. When the slide 9 is stopped by another limit member When a group of limit members stop, the flower slices will be blocked by several cuttings 10, and gaps 57 for the discharge of broken materials will be formed between adjacent cuttings 10. The whole piece of flower slices will not pass through the gap 57. The broken materials discharged from the gap 57 will be blocked by the fixed baffle 12 and eventually fall into the material guide box 13 from the broken material outlet 4. In summary, as the swing box 1 swings back and forth slowly, the broken materials in the flower slices will be screened out, and it is finally concluded that the flower slices are all whole materials. Then, when the screening is completed, the swing box 1 will swing to the whole material outlet 2 tilted downward, and the rotating baffle 3 will flip upward, so that the whole flower slices that fall on the supporting plate 8 will be discharged from the whole material outlet 2.
