Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine drying, and particularly relates to a rapid drying device and method for traditional Chinese medicine. Background Art

[0002] Traditional Chinese medicine decoction pieces are traditional Chinese medicines that have been specially processed and prepared, and can be directly used for dispensing or preparation. During the processing of traditional Chinese medicine decoction pieces, the traditional Chinese medicine is first cleaned, cut into slices, and then dried. In the prior art, when drying traditional Chinese medicine slices, the traditional Chinese medicine slices are placed on a drying support plate, and then multiple drying support plates are placed in a drying box, and the hot air in the drying box is used to heat them, absorb and take away the moisture in the medicinal materials, so as to realize the drying of the medicinal materials.

[0003] For example, in a patent document with the authorization announcement number CN207922770U and the name of a traditional Chinese medicine drying device, when traditional Chinese medicine needs to be dried, first open the warehouse door, place the traditional Chinese medicine on the traditional Chinese medicine storage rack, then close the warehouse door, start the motor, the fan and the heating plate, the motor drives the traditional Chinese medicine storage rack to rotate through the rotating shaft, and the fan blows air on the traditional Chinese medicine on the traditional Chinese medicine storage rack to dry the traditional Chinese medicine.

[0004] In view of the above related technologies, during the drying process, the hot air flows from bottom to top. Since the medicinal materials will obstruct the hot air when the hot air passes through the traditional Chinese medicine storage rack, the air flow passing through the traditional Chinese medicine storage rack from bottom to top gradually decreases, so that the tablets on the bottom traditional Chinese medicine storage rack are dried first, and the drying rate of the medicinal materials on the upper traditional Chinese medicine storage rack gradually slows down. As a result, while slowing down the overall drying rate of the traditional Chinese medicine in the drying warehouse, there is a chance that when the traditional Chinese medicine on the upper part is dried, the traditional Chinese medicine on the lower part is over-dried and scorched or discolored, which has a negative impact on the quality of the traditional Chinese medicine finished product. Summary of the Invention

[0005] In view of this, the present invention provides a rapid drying device and method for traditional Chinese medicine, aiming to solve the problem that the drying rate of the medicinal materials on the upper traditional Chinese medicine storage rack gradually slows down, thereby slowing down the overall drying rate of the traditional Chinese medicine in the drying warehouse.

[0006] To solve the above technical problems, in a first aspect, the present invention provides a rapid drying device for traditional Chinese medicines, which includes a drying chamber, a hatch, a fan, and air outlet holes; a scissor lift is arranged in the drying chamber, and a plurality of support plates for placing traditional Chinese medicines are vertically connected in the scissor lift. Ventilation holes are provided on the support plates, a transmission rack is fixedly connected to the bottom wall of the support plates, and a driving mechanism for driving the scissor lift to flip is fixedly connected to the side wall of the drying chamber; a fixing rod connected to the scissor lift is horizontally arranged between every two adjacent support plates, and a transmission gear capable of meshing with the transmission rack is rotatably connected to the fixing rod. A support shell is fixedly connected to the transmission gear, a sliding block is connected in the support shell, a guide air plate is fixedly connected to the sliding block, and when two adjacent support plates approach each other, the guide air plate can abut against the traditional Chinese medicines. An adjusting spring is fixedly connected between the sliding block and the support shell.

[0007] By adopting the above technical solution, on the one hand, the reciprocating rotation of the guide air plate can increase the uniformity of the contact between the traditional Chinese medicines and the air flow, improving the overall drying rate of the traditional Chinese medicines in the drying chamber. On the other hand, when the scissor lift flips, the guide air plate, the sliding block, and the adjusting spring cooperate to make the guide air plate move to squeeze the traditional Chinese medicines, reducing the moving distance of the traditional Chinese medicines during flipping while enabling the guide air plate to move a corresponding distance according to the thickness of the traditional Chinese medicines, reducing the probability of excessive extrusion of the traditional Chinese medicines by the guide air plate.

[0008] Optionally, the driving mechanism includes a rotation source fixedly connected to the outer side surface of the drying chamber, a driving gear is fixedly sleeved on the driving shaft of the rotation source, and a connecting gear is fixedly connected to the middle of the scissor lift, and the connecting gear can mesh with the driving gear.

[0009] Optionally, a connecting rod is fixedly connected between the support shell and the transmission gear, the connecting rod is rotatably connected to the fixing rod, and a reset torsion spring is fixedly connected between the connecting rod and the fixing rod.

[0010] By adopting the above technical solution, the reset torsion spring drives a plurality of guide air plates to be in a vertical state through the connecting rod, making the arrangement of the parts neat and uniform, and making the angles of the guide air plates relative to the horizontal plane equal when they rotate and tilt.

[0011] Optionally, the scissor lift includes a plurality of cross - arranged connecting rods, the middle parts of two adjacent connecting rods are hinged by a first pin shaft, and the two ends of two adjacent connecting rods are hinged by a second pin shaft. The first pin shaft is connected to the support plate, and the second pin shaft is connected to the fixing rod.

[0012] Optionally, a third pin shaft is fixedly connected to the side wall of the support plate. The third pin shaft is composed of a fixed shaft and a connecting shaft. The third pin shaft located in the middle in the vertical direction is the fixed shaft. The fixed shaft is fixedly connected with a support frame. The support frame is fixedly connected with a connecting gear. The support frame is provided with a sliding groove. The connecting shaft is slidably arranged in the sliding groove. The support frame is fixedly connected with a linear actuator. The driving shaft of the linear actuator is fixedly connected with one of the connecting shafts.

[0013] By adopting the above technical solution, the linear actuator drives a support plate to move in the vertical direction, and the support plate drives the remaining support plates to move through the cross - arranged connecting rods.

[0014] Optionally, the support plate is composed of a connecting frame and a tray. The connecting frame is in a C - shape. The connecting frame is connected with a scissor lift. The tray is slidably connected with the connecting frame, and the tray can slide out of the connecting frame.

[0016] Optionally, a heating plate is fixedly connected inside the drying bin.

[0017] By adopting the above technical solution, the heating plate can accelerate the drying rate of traditional Chinese medicine.

[0018] In a second aspect, the present invention provides a method for quickly drying Chinese medicinal materials, which is applied to the Chinese medicinal material quick - drying device described in the first aspect. The drying method is as follows: S1, Spread the sliced traditional Chinese medicine flat on the support plate, and the air flow passes upward through the support plate and is then output through the air outlet holes. S2, The scissor lift drives the support plate to reciprocate in the vertical direction, so that two adjacent support plates reciprocally approach and move away from each other. When the support plate moves, it drives the air guide plate to deflect from the vertical state to the inclined state to guide the air flow. S3, The scissor lift shrinks to the shortest position, the driving mechanism drives the scissor lift to flip 180°, the air guide plate can squeeze the traditional Chinese medicine. After the flipping is completed, the scissor lift extends, the support plate drives the air guide plate to rotate back to the original position, and the traditional Chinese medicine falls along the air guide plate to the next support plate.

[0019] By adopting the above technical solution, the support plate flips with the scissor lift, enabling the positions of the traditional Chinese medicine above and below the drying bin to be exchanged, making the traditional Chinese medicine alternately approach and move away from the fan. At the same time, when the traditional Chinese medicine flips with the support plate, the front and back sides of the traditional Chinese medicine also flip, increasing the uniformity of the contact between the air flow and the traditional Chinese medicine. While improving the overall drying rate of the traditional Chinese medicine in the drying bin, the drying effect of the traditional Chinese medicine is improved.

[0020] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. The reciprocating movement of the support plate in the vertical direction increases the air flow rate and improves the drying rate of traditional Chinese medicine. At the same time, the reciprocating rotation of the air guiding plate driven by the transmission gear and the transmission rack during the movement of the support plate can increase the uniformity of the contact between the traditional Chinese medicine and the air flow, improving the overall drying rate of the traditional Chinese medicine in the drying bin. On the other hand, when the scissor lift flips, the air guiding plate, the sliding block and the adjusting spring cooperate to move the air guiding plate to squeeze the traditional Chinese medicine, reducing the moving distance of the traditional Chinese medicine during flipping and enabling the air guiding plate to move a corresponding distance according to the thickness of the traditional Chinese medicine, reducing the probability of over-squeezing the traditional Chinese medicine by the air guiding plate.

[0021] 2.

Detailed implementation manners

[0024] For the purpose, technical solutions and advantages of the embodiments of the present invention to be clearer, the technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the Figures 1-9 of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0025] In a first aspect, this embodiment provides a rapid drying device for traditional Chinese medicine. Referring to Figure 1 , Figure 2 and Figure 3 , a rapid drying device for traditional Chinese medicine includes a drying bin 1, a scissor lift 2, a support plate 3 for placing traditional Chinese medicine, a drive mechanism 4 for driving the scissor lift 2 to turn over, and an air deflector 53 for guiding the air flow.

[0026] Referring to Figure 1 , Figure 2 and Figure 3 , the drying bin 1 stands on a horizontal plane. The drying bin 1 is hinged with a hatch 11. The lower end of the drying bin 1 is rotatably connected with a fan 12. The fan 12 is connected to an external power supply and can provide an air flow into the drying bin 1. An air outlet hole 13 is opened on the top wall of the drying bin 1 to make the air flow move from bottom to top. A heating plate 14 is fixedly connected inside the drying bin 1. The heating plate 14 is used to accelerate the drying rate of traditional Chinese medicine. The scissor lift 2 is rotatably arranged in the drying bin 1. A plurality of support plates 3 are arranged in the vertical direction, and the support plates 3 are fixedly connected with the support rods arranged crosswise with the scissor lift 2. Thus, when the scissor lift 2 extends, the support plates 3 move away from each other, and when the scissor lift 2 shortens, the support plates 3 approach each other. Ventilation holes 31 through which the air flow can pass are opened on the support plates 3. A transmission rack 32 is fixedly connected to the bottom wall of the support plate 3 (refer to Figure 5). The driving mechanism 4 is arranged on the outer side of the drying bin 1. The driving mechanism 4 is used to drive the scissor lift 2 to turn. Specifically, the scissor lift 2 turns 180° each time.

[0027] Refer to Figure 4 、 Figure 5 and Figure 6 , two fixing rods 5 are arranged between every two adjacent support plates 3 in the vertical direction. In the horizontal direction, the two fixing rods 5 are located at both ends of the scissor lift 2. The fixing rods 5 are connected to the inner side of the scissor lift 2. A transmission gear 51 that can mesh with the transmission rack 32 is rotatably connected to the two fixing rods 5. The transmission gear 51 is fixedly connected with a support housing 511 through a connecting rod 52. A sliding block 512 is vertically slidably connected in the support housing 511. The sliding block 512 is fixedly connected with a wind guide plate 53. An adjusting spring 513 is fixedly connected between the sliding block 512 and the support housing 511. The wind guide plate 53 is connected between the two sliding blocks 512. After two adjacent support plates 3 approach each other, the wind guide plate 53 can abut against the traditional Chinese medicine. In addition, when the wind guide plate 53 rotates to the horizontal state and abuts against the traditional Chinese medicine, the adjusting spring 513 is squeezed by a corresponding length according to the thickness of the traditional Chinese medicine.

[0028] When drying traditional Chinese medicine is needed, the sliced traditional Chinese medicine is laid flat on the support plate 3, and the topmost support plate 3 is not laid with traditional Chinese medicine. The fan 12 is started to convey air flow into the drying bin 1. The air flow passes upward through the support plate 3 and is then output through the air outlet holes 13, so as to dry the traditional Chinese medicine. During the drying process, the scissor lift 2 drives the support plate 3 to reciprocate in the vertical direction, so that two adjacent support plates 3 approach and move away from each other reciprocally, which can increase the air flow rate between the support plates 3. When the support plate 3 moves, it drives the transmission rack 32 to move. The transmission rack 32 moves and meshes with the transmission gear 51 to drive the transmission gear 51 to rotate self. The transmission gear 51 drives the wind guide plate 53 to deflect from the vertical state to the inclined state through the connecting rod 52, the support housing 511 and the sliding block 512. The vertically upward air flow passes through the wind guide plate 53 and dries the traditional Chinese medicine at other positions of the support plate 3 obliquely upward. The support plate 3 continuously reciprocates in the vertical direction, so that the wind guide plate 53 continuously rotates, increasing the uniformity of the contact between the air flow and the traditional Chinese medicine.

[0029] Then, the scissor lift 2 contracts to the shortest position, minimizing the distance between the support plates 3. At this time, the support plates 3 drive the transmission gear 51 to rotate through the transmission rack 32. The transmission gear 51 drives the air deflector 53 to rotate to the horizontal state through the connecting rod 52, the support housing 511, and the sliding block 512. While the support plates 3 move closer to each other, each support plate 3 moves closer to the air deflector 53 above it, enabling the lower surface of the horizontally positioned air deflector 53 to press the traditional Chinese medicine. The adjusting spring 513 adapts to the thickness of the traditional Chinese medicine and is compressed by a corresponding length, allowing the air deflector 53 to move a corresponding distance according to the thickness of the traditional Chinese medicine, reducing the probability of the air deflector 53 over-pressing the traditional Chinese medicine.

[0030] The driving mechanism 4 drives the scissor lift 2 to flip 180°. The air deflector 53 is used to press the traditional Chinese medicine to prevent the traditional Chinese medicine from moving and piling up when the scissor lift 2 flips. After the flipping is completed, the traditional Chinese medicine is located on the upper surface of the air deflector 53. The scissor lift 2 extends, and the support plates 3 move away from each other. The support plates 3 drive the air deflector 53 to rotate obliquely and finally to the vertical state through the transmission rack 32, the transmission gear 51, the connecting rod 52, the support housing 511, and the sliding block 512. When the air deflector 53 is inclined, the traditional Chinese medicine on the upper surface of the air deflector 53 falls onto the support plates 3 along the air deflector 53, and the air flow continues to dry the traditional Chinese medicine.

[0031] On the one hand, the reciprocating movement of the support plates 3 in the vertical direction increases the air flow rate and improves the drying rate of the traditional Chinese medicine. At the same time, the movement of the support plates 3 drives the reciprocating rotation of the air deflector 53 through the transmission gear 51 and the transmission rack 32, which can increase the uniformity of the contact between the traditional Chinese medicine and the air flow, improving the overall drying rate of the traditional Chinese medicine in the drying bin 1. On the other hand, when the scissor lift 2 flips, the air deflector 53, the sliding block 512, and the adjusting spring 513 cooperate to make the air deflector 53 move to press the traditional Chinese medicine. While reducing the moving distance of the traditional Chinese medicine during flipping, the air deflector 53 can move a corresponding distance according to the thickness of the traditional Chinese medicine, reducing the probability of the air deflector 53 over-pressing the traditional Chinese medicine.

[0032] The support plates 3 flip with the scissor lift 2, enabling the positions of the traditional Chinese medicine above and below the drying bin 1 to be exchanged. As a result, the traditional Chinese medicine alternately approaches and moves away from the fan. At the same time, when the traditional Chinese medicine flips with the support plates 3, the front and back sides of the traditional Chinese medicine also flip, increasing the uniformity of the contact between the air flow and the traditional Chinese medicine, improving the overall drying rate of the traditional Chinese medicine in the drying bin 1 and enhancing the drying effect of the traditional Chinese medicine.

[0033] Refer to Figure 2 、 Figure 3 and Figure 7, the driving mechanism 4 includes a rotating source 41, a driving gear 42, and a connecting gear 43. The rotating source 41 is fixedly connected to the outer side of the drying bin 1. The driving gear 42 is fixedly sleeved on the driving shaft of the rotating source 41. The connecting gear 43 is fixedly connected to the middle of the scissor lift 2, and the connecting gear 43 can mesh with the driving gear 42. The rotating source 41 drives the scissor lift 2 to flip through the driving gear 42 and the connecting gear 43 in sequence.

[0034] Refer to Figure 5 , the connecting rod 52 is rotatably connected to the fixed rod 5, and a return torsion spring 521 is fixedly connected between the connecting rod 52 and the fixed rod 5. Since there are multiple air guiding plates 53, when the transmission rack 32 disengages from the transmission gear 51, the return torsion spring 521 drives the multiple air guiding plates 53 to be in a vertical state through the connecting rod 52, making the arrangement of parts neat and uniform, and making the angles of the multiple air guiding plates 53 relative to the horizontal plane equal when they rotate and tilt.

[0035] Refer to Figure 3 , Figure 4 and Figure 8 , the scissor lift 2 includes connecting rods 21, a first pin shaft 22, and a second pin shaft 23. Multiple connecting rods 21 are arranged in an array in the vertical direction. The connecting rods 21 are arranged obliquely and crosswise, and the adjacent two connecting rods 21 in the vertical direction are connected end to end. The connecting rods 21 are hinged through the first pin shaft 22 and the second pin shaft 23. The first pin shaft 22 is located in the middle of the connecting rod 21, and the second pin shaft 23 is located at both ends of the connecting rod 21. The first pin shaft 22 is fixedly hinged to the support plate 3, and the second pin shaft 23 is fixedly connected to the fixed rod 5.

[0036] Refer to Figure 3 , Figure 4 and Figure 8 , a third pin shaft 26 is fixedly connected to the side wall of the support plate 3. The third pin shaft 26 is composed of a fixed shaft 261 and a connecting shaft 262. The third pin shaft 26 located in the middle in the vertical direction is the fixed shaft 261, and the remaining third pin shafts 26 are connecting shafts 262. The fixed shaft 261 is fixedly connected to a support frame 24. The support frame 24 is fixedly connected to the connecting gear 43. Four sliding grooves 241 are formed in the support frame 24. The four sliding grooves 241 are evenly distributed at both ends of the support frame 24 in the horizontal direction and are evenly distributed on both sides of the fixed shaft 261 in the vertical direction. The connecting shaft 262 is slidably arranged in the sliding groove 241. A linear actuator 25 is fixedly connected to the support frame 24. The linear actuator 25 is located at both ends of the support frame 24 in the horizontal direction. The drive shaft of the linear actuator 25 is fixedly connected to one of the connecting shafts 262 in the sliding groove 241. The linear actuator 25 drives one support plate 3 to move in the vertical direction through the connecting shaft 262, and this support plate 3 drives the remaining support plates 3 to move through the cross - arranged connecting rods 21.

[0037] Refer to Figure 9, the support plate 3 is composed of a connecting frame 33 and a tray 34. The connecting frame 33 is in a U shape and is connected to the scissor lift 2. The tray 34 is slidably connected to the connecting frame 33, and the tray 34 can slide away from the connecting frame 33, thus facilitating the replacement and cleaning of the tray 34.

[0038] The implementation principle of a rapid drying device for traditional Chinese medicine in an embodiment of the present invention is as follows: The sliced traditional Chinese medicine is laid flat on the support plate 3, and the air flow passes upward through the support plate 3 and is then output through the air outlet holes 13. The scissor lift 2 drives the support plate 3 to reciprocate in the vertical direction, causing two adjacent support plates 3 to reciprocally approach and move away from each other, which can increase the air flow rate between the support plates 3. When the support plate 3 moves, it drives the air guide plate 53 to deflect from the vertical state to the inclined state through the transmission rack 32, the transmission gear 51, and the connecting rod 52. The vertically upward air flow passes through the air guide plate 53 obliquely upward. The support plate 3 continuously reciprocates in the vertical direction, causing the air guide plate 53 to continuously rotate, increasing the uniformity of the contact between the air flow and the traditional Chinese medicine.

[0039] Then, the scissor lift 2 contracts to the shortest position, making the distance between the support plates 3 the shortest. At this time, the support plate 3 drives the air guide plate 53 to rotate to the horizontal state through the transmission rack 32, the transmission gear 51, and the connecting rod 52. The driving mechanism 4 drives the scissor lift 2 to flip 180°. The air guide plate 53 is used to squeeze the traditional Chinese medicine to prevent the traditional Chinese medicine from moving and piling up together when the scissor lift 2 flips. After flipping, the traditional Chinese medicine is located on the upper surface of the air guide plate 53. The scissor lift 2 extends, and the support plates 3 move away from each other. The support plate 3 drives the air guide plate 53 to rotate obliquely and finally to the vertical state through the transmission rack 32, the transmission gear 51, and the connecting rod 52. When the air guide plate 53 is inclined, the traditional Chinese medicine on the upper surface of the air guide plate 53 falls along the air guide plate 53 to the support plate 3, and the air flow continues to dry the traditional Chinese medicine.

[0040] In a second aspect, an embodiment of the present invention provides a rapid drying method for traditional Chinese medicine, which is applied to a rapid drying device for traditional Chinese medicine in the first aspect. The drying method is as follows: S1, lay the sliced traditional Chinese medicine flat on the support plate 3, and the air flow passes upward through the support plate 3 and is then output through the air outlet holes 13; S2, the scissor lift 2 drives the support plate 3 to reciprocate in the vertical direction, causing two adjacent support plates 3 to reciprocally approach and move away from each other. When the support plate 3 moves, it drives the air guide plate 53 to deflect from the vertical state to the inclined state to guide the air flow; S3, the scissor lift 2 contracts to the shortest position, the driving mechanism 4 drives the scissor lift 2 to flip 180°, the air guide plate 53 can squeeze the traditional Chinese medicine. After flipping, the scissor lift 2 extends, and the support plate 3 drives the air guide plate 53 to rotate back to the original position, and the traditional Chinese medicine falls along the air guide plate 53 to the next support plate 3.

[0041] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The above are the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
