Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine preparation technology, and in particular to a processing apparatus for preparing traditional Chinese medicine decoction pieces. Background Technology

[0002] In the preparation process of Chinese herbal medicine slices, heating and processing is the core process that determines the efficacy, medicinal properties and safety of the slices. Through heating and processing, the transformation and optimization of Chinese herbal medicine components can be achieved.

[0003] Currently, most mainstream Chinese herbal medicine (TCM) processing devices employ a structure design of fixed containers combined with stirring components. While the stirring components can evenly disperse the TCM slices during processing, these slices often still tend to pile up. Due to the release of oils and mucilage during the processing, the TCM slices are prone to sticking together. Once stuck together, even with the stirring components running, it's difficult to separate them. This results in uneven heating; overheated slices are prone to scorching, while underheated slices are insufficiently processed. Consequently, a batch of TCM slices may contain both overcooked and undercooked pieces, affecting the quality of the processed herbs and, in severe cases, even compromising their safety. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where medicinal herbs tend to stick together when heated and processed, leading to uneven heating and affecting the processing effect. Therefore, this invention proposes a processing device for preparing medicinal herbs.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A processing apparatus for preparing traditional Chinese medicine decoction pieces includes a shell, a heat-insulating cylinder fixedly mounted on the shell, and an inner cylinder rotatably mounted inside the heat-insulating cylinder. The outer end wall of the inner cylinder has uniformly distributed micropores penetrating through it, and the micropores are located inside the heat-insulating cylinder. A servo motor for driving the rotation of the inner cylinder is fixedly mounted on the shell. Baffles are fixedly mounted on the upper and right sides of the inner end wall of the heat-insulating cylinder, and the baffles slide against the outer end wall of the inner cylinder. The heat-insulating cylinder and the inner cylinder are separated into a first chamber and a second chamber by the two baffles. An electric heating component is fixedly mounted in the first chamber. A fan is fixedly mounted on the shell, and the air inlet of the fan is connected to the interior of the first chamber.

[0007] Preferably, the front of the shell is provided with a feed inlet that communicates with the central axis of the inner cylinder, and a first movable door for sealing the feed inlet is rotatably connected to the shell, and the first movable door is provided with evenly distributed air inlets.

[0008] Preferably, the front of the shell has a discharge port that communicates with the inner edge of the inner cylinder, a second movable door for sealing the discharge port is rotatably connected to the shell, and a receiving hopper located below the discharge port is fixedly installed on the front of the shell.

[0009] Preferably, the electric heating components are arranged in an S-shape around the left side of the first chamber, the air outlet of the fan is connected to the inside of the inner cylinder, and a filter box is fixedly installed on the air outlet of the fan.

[0010] Preferably, a plurality of connecting rods are fixedly installed on the shell and run longitudinally through the inner cylinder. A plurality of first guide plates are provided at the lower left position inside the inner cylinder, and a plurality of second guide plates are provided at the upper left position inside the inner cylinder. The first and second guide plates are evenly distributed around the inner end wall of the inner cylinder. The first and second guide plates slide against the inner end wall of the inner cylinder and are fixedly connected to the connecting rods.

[0011] Preferably, the first guide plate and the second guide plate are inclined in opposite directions, with the rear end of the first guide plate inclined clockwise along the inner cylinder and the front end of the second guide plate inclined clockwise along the inner cylinder.

[0012] Preferably, a shovel plate is fixedly installed on the shell, extending longitudinally through the inner cylinder. The shovel plate slides against the inner end wall of the inner cylinder on one side in the counterclockwise direction, and the shovel plate is correspondingly arranged with the second chamber.

[0013] Preferably, a third guide plate is fixedly installed on the shell, extending longitudinally through the inner cylinder, and the third guide plate slides against the inner end wall of the inner cylinder. The third guide plate is located at the lower right side of the inner cylinder, and the front end of the third guide plate is inclined counterclockwise along the inner cylinder.

[0014] Preferably, a sealing plate is fixedly connected between the shovel plate and the third guide plate, with the front and rear ends of the sealing plate penetrating the interior of the inner cylinder and fixedly connected to the shell.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, by uniformly opening micropores on the outer end wall of the inner cylinder and setting a first chamber and a second chamber on the outer side of the inner cylinder, the airflow suction combined with the rotation of the inner cylinder can not only evenly spread the Chinese herbal medicine slices on the inner end wall of the inner cylinder, but also quickly remove impurities such as oil, mucus and dust generated during the processing of the Chinese herbal medicine slices. With this dual approach, the probability of the Chinese herbal medicine slices sticking together during the processing can be further reduced, which is conducive to improving the uniformity of heating during the heating and processing of Chinese herbal medicine slices and effectively improving the quality of the processed Chinese herbal medicine slices.

[0018] 2. In this invention, by connecting the air outlet of the blower to the inside of the inner cylinder, the airflow generated by the blower drawing air from the inside of the inner cylinder through the first chamber can be returned to the inner cylinder. This not only allows the residual heat generated by the electric heating component to be returned to the inner cylinder through airflow circulation, but also enables the simultaneous heating and processing of Chinese herbal medicine slices from both the inside and outside sides through airflow circulation. This helps to save energy and further improves the uniformity of heating during the processing of Chinese herbal medicine slices, thereby effectively improving the heating and processing effect of Chinese herbal medicine slices by this device.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example: This example provides a processing apparatus for preparing traditional Chinese medicine decoction pieces. See [link to example]. Figure 1 - Figure 11 Specifically, it includes a shell 1, an insulation cylinder 11 fixedly mounted on the shell 1, and an inner cylinder 12 rotatably mounted inside the insulation cylinder 11. The outer end wall of the inner cylinder 12 is provided with uniformly distributed micro-holes, and the micro-holes are located inside the insulation cylinder 11. A servo motor 13 for driving the inner cylinder 12 to rotate is fixedly mounted on the shell 1. A gear ring 4 is fixedly mounted around the outer end wall of the inner cylinder 12 and is disposed outside the insulation cylinder 11. A gear 41 that meshes with the gear ring 4 is rotatably mounted on the shell 1, and the gear 41 is connected to the drive shaft of the servo motor 13.

[0038] The front of the housing 1 is provided with a feed inlet 14 that communicates with the central axis of the inner cylinder 12. A first movable door 15 for sealing the feed inlet 14 is rotatably connected to the housing 1, and the first movable door 15 is provided with evenly distributed air inlets. The front of the housing 1 is provided with a discharge outlet 16 that communicates with the inner edge of the inner cylinder 12. A second movable door 17 for sealing the discharge outlet 16 is rotatably connected to the housing 1. A receiving hopper 18 located below the discharge outlet 16 is fixedly installed on the front of the housing 1.

[0039] A partition 2 is fixedly installed on the upper and right sides of the inner end wall of the heat insulation cylinder 11, and the partition 2 slides and fits against the outer end wall of the inner cylinder 12. The heat insulation cylinder 11 and the inner cylinder 12 are separated into a first chamber 21 and a second chamber 22 by the two partitions 2. An electric heating component 23 is fixedly installed in the first chamber 21, and a fan 24 is fixedly installed on the shell 1, and the air inlet of the fan 24 is connected to the inside of the first chamber 21.

[0040] When using the device, the staff heats and processes the Chinese herbal medicine slices. The staff flips the first movable door 15 to open the feed port 14 and puts an appropriate amount of Chinese herbal medicine slices into the inner cylinder 12 through the feed port 14. Then, the staff flips the first movable door 15 in the opposite direction to close the feed port 14 again, so that a relatively closed space is formed inside the inner cylinder 12. Then, the servo motor 13 is powered on and starts, driving the gear 41 connected to its drive shaft to rotate. Then, with the meshing of the gear 41 and the gear ring 4, the inner cylinder 12 is driven to rotate clockwise inside the heat preservation cylinder 11.

[0041] Simultaneously, the blower 24 is powered on and starts to evacuate the first chamber 21. Under the suction of the airflow, the air in the inner cylinder 12 passes through the micro-holes on the outer end wall of the inner cylinder 12 and enters the first chamber 21. Then it is drawn away by the blower 24. Due to the negative pressure formed by the airflow at the micro-holes, the Chinese herbal medicine pieces that are attached to the inner end wall of the inner cylinder 12 can be stably adsorbed. With the continuous clockwise rotation of the inner cylinder 12, the Chinese herbal medicine pieces are carried by the inner cylinder 12 and move upward in a clockwise direction within the inner cylinder 12. During this process, the Chinese herbal medicine pieces that are not attached to the inner end wall of the inner cylinder 12 will slide to the bottom of the inner cylinder 12 under gravity. The above operation continues. During the continuous clockwise rotation of the inner cylinder 12, the Chinese herbal medicine pieces can be gradually laid flat on the inner end wall of the inner cylinder 12.

[0042] As the Chinese herbal medicine slices are gradually laid flat on the inner wall of the inner cylinder 12, the electric heating component 23 is powered on and starts heating in the first chamber 21. This allows the Chinese herbal medicine slices laid flat on the inner wall of the inner cylinder 12 to be heated and processed. When the Chinese herbal medicine slices move to the upper right position inside the inner cylinder 12 under the continuous rotation of the inner cylinder 12, the Chinese herbal medicine slices are in the area corresponding to the second chamber 22. The second chamber 22 is not connected to the fan 24, so when the micropores are aligned with the second chamber 22, no negative pressure suction will be formed inside. In this state, the Chinese herbal medicine slices are no longer stably adsorbed on the inner wall of the inner cylinder 12. Affected by gravity, the Chinese herbal medicine slices fall downwards and fall back to the bottom position inside the inner cylinder 12. With the continuous rotation of the inner cylinder 12 and the continuous suction of the airflow, the Chinese herbal medicine slices are continuously laid flat, fall, and then laid flat again inside the inner cylinder 12, effectively ensuring the uniformity of heating of the Chinese herbal medicine slices.

[0043] As the inner cylinder 12 rotates, the Chinese herbal medicine slices move from the bottom position to the top position inside the inner cylinder 12. During this process, the Chinese herbal medicine slices are rotated 180°. This ensures that when the Chinese herbal medicine slices fall from the top position inside the inner cylinder 12, the other side is in contact with the inner end wall of the bottom of the inner cylinder 12. Through repeated cycles, the Chinese herbal medicine slices are automatically flipped, which can further improve the uniformity of heating during the processing of Chinese herbal medicine slices. By controlling the clockwise rotation speed of the inner cylinder 12, the duration of continuous heating on one side of the Chinese herbal medicine slices can be adjusted, making the operation flexible and convenient.

[0044] After the processing of Chinese herbal medicine slices is completed, the staff flips the second movable door 17 to open the discharge port 16. The processed Chinese herbal medicine slices can be discharged from the inner cylinder 12 through the second movable door 17, and then, with the guidance of the receiving hopper 18, a smoother and more stable collection operation is carried out.

[0045] In this device, by combining airflow suction with the rotation of the inner cylinder 12, not only can the Chinese herbal medicine slices be evenly spread on the inner end wall of the inner cylinder 12, but also impurities such as oil, mucus and dust generated during the processing of the Chinese herbal medicine slices can be quickly removed with the help of airflow suction. With this dual combination, the probability of the Chinese herbal medicine slices sticking together during the processing can be further reduced, which is conducive to improving the uniformity of heating during the heating and processing of Chinese herbal medicine slices and effectively improving the quality of the processed Chinese herbal medicine slices.

[0046] In the specific implementation process, such as Figure 1 , Figure 7 , Figure 8 and Figure 10 As shown, the electric heating component 23 is arranged in an S-shape around the left side of the first chamber 21. The air outlet of the fan 24 is connected to the inside of the inner cylinder 12. A filter box 25 is fixedly installed on the air outlet of the fan 24. When the device is in use, by setting the electric heating component 23 to an S-shaped structure, the electric heating component 23 can heat the Chinese herbal medicine slices laid flat on the inner wall of the inner cylinder 12 more evenly in the first chamber 21. By concentrating the electric heating component 23 on the left side of the first chamber 21, it can avoid the Chinese herbal medicine slices being overheated when stacked at the bottom of the inner cylinder 12, and prevent the Chinese herbal medicine slices from releasing oil due to heating when stacked at the bottom of the inner cylinder 12. This can ensure the stability of the Chinese herbal medicine slices laid flat on the inner wall of the inner cylinder 12 during the heating and processing process, thanks to the continuous rotation of the inner cylinder 12 and the airflow suction.

[0047] In this device, the air outlet of the blower 24 is fixedly connected to the inside of the inner cylinder 12. This allows the airflow generated by the blower 24 drawing air from the inside of the inner cylinder 12 through the first chamber 21 to be sent back into the inner cylinder 12. Not only can the residual heat generated by the electric heating component 23 be sent back into the inner cylinder 12 through the airflow circulation, but the traditional Chinese medicine slices can also be heated and processed from both the inside and outside sides simultaneously by the airflow circulation. This not only saves energy consumption, but also further improves the uniformity of heating during the processing of traditional Chinese medicine slices, which is conducive to improving the effect of heating and processing traditional Chinese medicine slices.

[0048] When the device is in operation, by fixing the filter box 25 to the air outlet of the blower 24, it can prevent dust and impurities generated during the processing of Chinese herbal medicine pieces from being sucked back into the blower 24 when the return airflow stops. The filter box 25 is also installed between the air inlet of the blower 24 and the first chamber 21, which can prevent dust and grease in the Chinese herbal medicine pieces from entering the blower 24 during continuous air extraction. With the cooperation of these two parts, the stability of the device during operation can be effectively guaranteed.

[0049] In the specific implementation process, such as Figure 3 , Figure 4 , Figure 7 - Figure 8 and Figure 10 - Figure 11 As shown, multiple connecting rods 3 are fixedly installed on the shell 1, extending longitudinally through the inner cylinder 12. Multiple first guide plates 31 are arranged at the lower left position inside the inner cylinder 12, and multiple second guide plates 32 are arranged at the upper left position inside the inner cylinder 12. The first guide plates 31 and second guide plates 32 are evenly distributed around the inner end wall of the inner cylinder 12. The first guide plates 31 and second guide plates 32 slide against the inner end wall of the inner cylinder 12. The first guide plates 31 and second guide plates 32 are fixedly connected to the connecting rods 3. The first guide plates 31 and second guide plates 32 are inclined in opposite directions. The rear end of the first guide plate 31 is inclined clockwise along the inner cylinder 12, and the front end of the second guide plate 32 is inclined clockwise along the inner cylinder 12.

[0050] In use, the device securely connects the first guide plate 31 and the second guide plate 32 to the housing 1 via the connecting rod 3. This ensures the structural stability of the first guide plate 31 and the second guide plate 32, and guarantees the stability of their sliding contact with the inner wall of the inner cylinder 12. Since the first guide plate 31 is positioned on the lower left side inside the inner cylinder 12, and its rear end is inclined clockwise along the inner cylinder 12, the herbal medicine pieces adsorbed on the inner wall of the inner cylinder 12 can be guided backward by the multiple first guide plates 31 during the clockwise rotation of the inner cylinder 12. Similarly, by setting the second guide plate 32 on the upper left side inside the inner cylinder 12 and tilting the front end of the second guide plate 32 clockwise along the inner cylinder 12, the Chinese herbal medicine pieces adsorbed on the inner end wall of the inner cylinder 12 can move forward under the guidance of multiple second guide plates 32 during the clockwise rotation of the inner cylinder 12. The multiple first guide plates 31 and second guide plates 32 cooperate with each other to further improve the dispersion and uniformity of the Chinese herbal medicine pieces laid flat and attached to the inner end wall of the inner cylinder 12, ensuring that the device can process a larger number of Chinese herbal medicine pieces at a time, which is conducive to ensuring production efficiency.

[0051] In the specific implementation process, such as Figure 3 , Figure 5 and Figure 8 - Figure 10 As shown, a shovel plate 33 is fixedly installed on the housing 1, extending longitudinally through the inner cylinder 12. The shovel plate 33 slides against the inner end wall of the inner cylinder 12 on one side in the counterclockwise direction. The shovel plate 33 is correspondingly arranged with the second chamber 22. When the device is in use, under normal circumstances, the Chinese herbal medicine slices enter the area corresponding to the second chamber 22 under the rotation of the inner cylinder 12. After losing the suction of the airflow, the Chinese herbal medicine slices will automatically separate from the inner end wall of the inner cylinder 12 and fall downwards. However, there may be some Chinese herbal medicine slices that stick to the inner end wall of the inner cylinder 12. In this case, by sliding the shovel plate 33 against the inner end wall of the inner cylinder 12 and setting the shovel plate 33 in the area corresponding to the second chamber 22, the Chinese herbal medicine slices that have not fallen off naturally can be shoveled off by the shovel plate 33, which helps to ensure the stability of the continuous operation of the device.

[0052] In the specific implementation process, such as Figure 3 , Figure 5 and Figure 8 - Figure 10As shown, a third guide plate 34 is fixedly installed on the shell 1, extending longitudinally through the inner cylinder 12. The third guide plate 34 slides against the inner end wall of the inner cylinder 12. The third guide plate 34 is located on the lower right side inside the inner cylinder 12. The front end of the third guide plate 34 is inclined counterclockwise along the inner cylinder 12. A sealing plate 35 is fixedly connected between the shovel plate 33 and the third guide plate 34. The front and rear ends of the sealing plate 35 penetrate the interior of the inner cylinder 12 and are fixedly connected to the shell 1. When the device is in use, the front end of the third guide plate 34 is positioned corresponding to the discharge port 16. The third guide plate 34 is located in the area corresponding to the first chamber 21. After the Chinese herbal medicine slices are heated and processed, the process... The operator can control the inner cylinder 12 to rotate counterclockwise and maintain the airflow suction operation in the first chamber 21. The airflow suction makes the Chinese herbal medicine pieces fit tightly against the inner end wall of the inner cylinder 12. With the counterclockwise rotation of the inner cylinder 12, the Chinese herbal medicine pieces move towards the third guide plate 34 in the counterclockwise direction inside the inner cylinder 12. Since the front end of the third guide plate 34 is inclined in the counterclockwise direction inside the inner cylinder 12, the Chinese herbal medicine pieces dispersed at the bottom of the inner cylinder 12 can move forward continuously with the help of the inclination of the third guide plate 34. Finally, they are discharged through the discharge port 16 opened at the front, which can effectively realize the smooth feeding operation of the Chinese herbal medicine pieces.

[0053] In this device, by fixing the sealing plate 35 between the shovel plate 33 and the third guide plate 34, a closed structure can be formed between the shovel plate 33 and the third guide plate 34. This helps to prevent the Chinese medicine slices from accidentally falling between the shovel plate 33 and the third guide plate 34 during the use of the device, thus avoiding accidental accumulation and ensuring the stability of the device during long-term operation.

[0054] Specifically, the working principle of this invention is as follows:

[0055] The operator flips the first movable door 15 to open the feed inlet 14, and puts an appropriate amount of Chinese herbal medicine slices into the inner cylinder 12 through the feed inlet 14. Then, the servo motor 13, electric heating component 23, and fan 24 are powered on and started. The servo motor 13 drives the gear 41 to rotate. With the meshing of the gear 41 and the gear ring 4, the inner cylinder 12 is driven to rotate clockwise inside the insulation cylinder 11. The electric heating component 23 heats the first chamber 21, and the fan 24 evacuates the first chamber 21, so that the air inside the inner cylinder 12 passes through the micro-holes on the outer end wall of the inner cylinder 12 and enters the first chamber 21. Under the influence of the negative pressure formed by the airflow at the micro-holes, the Chinese herbal medicine slices that are attached to the inner end wall of the inner cylinder 12 can be stably adsorbed. With the continuous clockwise rotation of the inner cylinder 12, the Chinese herbal medicine slices move upward in a clockwise direction inside the inner cylinder 12. The Chinese herbal medicine slices that are not attached to the inner wall of the inner cylinder 12 will slide down to the bottom of the inner cylinder 12 under gravity. With the guidance of the first guide plate 31 and the second guide plate 32, the Chinese herbal medicine slices are gradually laid flat on the left inner wall of the inner cylinder 12 for heating and processing. When the Chinese herbal medicine slices move to the area corresponding to the second chamber 22 on the upper right side of the inner cylinder 12, the Chinese herbal medicine slices are no longer affected by the airflow and fall back to the bottom of the inner cylinder 12. With the continuous rotation of the inner cylinder 12 and the continuous airflow, the Chinese herbal medicine slices are continuously laid flat, fall, and then laid flat again in the inner cylinder 12. With the circulation of hot airflow, the Chinese herbal medicine slices are evenly heated. After processing, it is only necessary to flip the second movable door 17 to open the discharge port 16 and operate the inner cylinder 12 to rotate counterclockwise. With the guidance of the third guide plate 34, the Chinese herbal medicine slices can be controlled to move forward and be smoothly discharged from the discharge port 16.

[0056] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
