Description

Technical Field

[0001] This invention relates to the field of pharmaceutical equipment technology, and in particular to a processing device and method for traditional Chinese medicine decoction pieces. Background Technology

[0002] Before Chinese medicinal herbs can be used in medicine, they need to be processed. The main processing methods are stir-frying, scalding, and calcining. Scalding is also known as sand scalding.

[0003] Patent publication number CN209933517U discloses a processing device for traditional Chinese medicine decoction pieces, including a box body, a stirring device, and a wall scraper. The upper end of one side of the box body is provided with a feeding port. When processing traditional Chinese medicine decoction pieces using a hot-frying method, sand is put into the box body through the feeding port, and then the sand is heated by the heat of an electric heating plate. Then, the medicinal materials are put into the heated sand. When there are many medicinal materials to be processed, the medicinal materials and sand will accumulate in the box body. If the sand used is clean river sand, due to the poor fluidity, heat retention and heat transfer of clean river sand, the medicinal materials accumulated in the middle are difficult to be heated, resulting in uneven heating of the medicinal materials and poor medicinal properties after processing.

[0004] To address the aforementioned shortcomings, we have designed a traditional Chinese medicine processing device and method that can uniformly heat medicinal materials when processing them using clean river sand. Summary of the Invention

[0009] As a further preferred embodiment, a stirring mechanism is also included. The stirring mechanism includes a stirring frame, a fixed frame, a torsion spring, a pull rope, a pulling frame, and a fixed block. Fixed frames are evenly connected from top to bottom on the left side of the stirring frame. Stirring frames are rotatably connected to the fixed frames. Torsion springs are connected between the left side of the stirring frame and the right side of the fixed frame. The torsion springs are all wound around the left side of the stirring frame. Pull ropes are all wound around the right side of the stirring frame. A pulling frame is slidably connected to the right rear of the stirring frame. The rear side of the pull rope is connected to the pulling frame. Fixed blocks are evenly connected along the circumference of the inner wall of the iron pot. The fixed blocks are pressed and fitted with the right side of the pulling frame.

[0010] As a further preferred embodiment, it also includes an air intake mechanism, which includes an air storage tank, a piston rod, a return spring, a connecting pipe, and a pressing block. The air storage tank is connected to the lower left wall of the oven, and the air storage tank has a built-in one-way valve. The connecting pipe is connected to the lower right side of the air storage tank and is connected to the air storage tank. The left side of the connecting pipe is connected to the lower right side of the heat conduction pipe. The piston rod is slidably connected inside the air storage tank. The left side of the piston rod slides out of the left side of the oven. A push-pull frame is connected to the left side of the piston rod. A return spring is connected between the lower right side of the push-pull frame and the left side of the oven. The return spring is wound around the piston rod. A pressing block is connected to the top left side of the stirring rack. The pressing block is pressed and engaged with the upper right side of the push-pull frame.

[0011] As a further preferred embodiment, a venting mechanism is also included, which includes a venting frame, a connecting spring, and a sealing cover. A vent is opened in the upper left part of the stirring frame, and the venting frame is connected inside the venting frame. The sealing cover is slidably connected to the upper part of the venting frame, and a connecting spring is connected between the upper right part of the sealing cover and the upper left part of the venting frame.

[0012] As a further preferred embodiment, a scraping mechanism is also included, which includes a scraping frame and a compression spring. The scraping frame is slidably connected to the lower right front side of the stirring frame. The scraping frame is in contact with the inner bottom wall of the iron pot, and a compression spring is connected between the upper part of the scraping frame and the stirring frame.

[0013] A method for processing traditional Chinese medicine decoction pieces, the steps of which are as follows:

[0014] S1: First, put the clean river sand into the iron pot, then turn on the heating machine to heat the clean river sand in the iron pot. When the clean river sand reaches the appropriate temperature, put the medicinal materials into the heated clean river sand.

[0015] S2: Turn on the motor to drive the stirring rack to stir-fry the clean river sand and medicinal materials. The heat from the roasting machine will also enter the stirring rack through the heat pipe and the air pipe to assist the stirring rack in heating the clean river sand and medicinal materials in the middle.

[0016] S3: When stir-frying clean river sand and medicinal materials, the stirring rack will stir the clean river sand and medicinal materials from top to bottom to assist in the processing of medicinal materials;

[0017] S4: After the medicinal materials have been processed, turn off the baking machine and motor, and then take out the processed medicinal materials.

[0018] The present invention has the following advantages: 1. The present invention uses a stirring rack to stir the clean river sand and medicinal materials, which can make the medicinal materials heat evenly. Furthermore, the heat from the baking machine enters the stirring rack, which can heat the medicinal materials in the middle, improving the uniformity of heating and making the medicinal properties of the processed medicinal materials better.

[0019] 2. This invention uses a reversible mixing rack to mix clean river sand and medicinal materials from top to bottom, thereby enhancing the uniformity of heating of the medicinal materials and improving their quality.

[0020] 3. When the stirring rack of the present invention stirs the medicinal materials and drives the extrusion block to rotate, the cooperation between the gas storage tank, piston rod, connecting pipe and push-pull frame can accelerate the speed at which heat enters the heat conduction pipe in the baking machine and improve the efficiency of the stirring rack in heating the medicinal materials.

[0021] 4. By shifting the sealing cover to the right, the upper part of the fixing frame is no longer blocked, which allows for the venting of the mixing frame and facilitates the delivery of hot air into the mixing frame.

[0022] 5. This invention uses a rotating scraper to scrape off medicinal materials stuck to the bottom of an iron pot, which facilitates the processing of the medicinal materials and makes the processing effect better. Attached Figure Description

Detailed Implementation

[0040] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0041] Example 1

[0042] A device for processing Chinese medicinal herbs, such as Figure 1 and Figure 2 As shown, it includes a baking machine 1, an iron pot 2, a stirring mechanism 3, and a heating mechanism 4. The iron pot 2 is installed in the middle of the baking machine 1. The stirring mechanism 3 is located on the upper left side of the baking machine 1. The stirring mechanism 3 can stir the clean river sand and medicinal materials in the iron pot 2. The heating mechanism 4 is located on the lower left side of the baking machine 1. The heating mechanism 4 can heat the medicinal materials piled in the middle through the stirring mechanism 3.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stirring mechanism 3 includes a motor 31, a stirring frame 32, and a support frame 33. The support frame 33 is welded to the upper left side of the baking machine 1. The motor 31 is bolted to the upper right side of the support frame 33. The output shaft of the motor 31 rotates through the upper right part of the support frame 33. The motor 31 is located above the iron pot 2. The stirring frame 32 is connected to the bottom of the output shaft of the motor 31 through a coupling.

[0044] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the heating mechanism 4 includes a heat-conducting pipe 41 and a vent pipe 42. The stirring rack 32 has a venting groove 43 inside. The vent pipe 42 is connected to the upper part of the output shaft of the motor 31. The lower part of the vent pipe 42 is fixed to the stirring rack 32 and is connected to the venting groove 43. The heat-conducting pipe 41 is connected to the lower left side of the baking machine 1. The lower right side of the heat-conducting pipe 41 is connected to the baking machine 1. The upper right part of the heat-conducting pipe 41 passes through the upper part of the support frame 33 and is rotatably connected to and connected to the vent pipe 42.

[0045] When using this herbal medicine processing device, first, clean river sand is placed into the iron pot 2. Then, the heating machine 1 is turned on to heat the clean river sand in the iron pot 2. When the sand temperature reaches a suitable level, the medicinal materials to be processed are placed into the iron pot 2. Then, the motor 31 is turned on, causing the output shaft of the motor 31 to drive the stirring rack 32 to rotate counterclockwise, thus stir-frying the clean river sand and medicinal materials in the iron pot 2. This ensures that the medicinal materials are heated evenly. At the same time, when the heating machine 1 is turned on, the heat inside the heating machine 1 is also transferred through the heat pipe 41 and the ventilation... The air pipe 42 enters the mixing rack 32 and heats the mixing rack 32. This allows the mixing rack 32 to heat the clean river sand and medicinal materials in the middle while mixing them, improving the uniformity of heating of the medicinal materials and thus improving the processing effect. After the medicinal materials are processed, the baking machine 1 and the motor 31 are turned off, and then the processed medicinal materials are taken out of the iron pot 2. The above operation can be repeated to process the medicinal materials. During the processing, the medicinal materials can be heated evenly, which improves the medicinal properties of the processed medicinal materials.

[0046] Example 2

[0047] Based on Example 1, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown, it also includes a stirring mechanism 5, which includes a stirring frame 51, a fixed frame 52, a torsion spring 53, a pull rope 54, a pulling frame 55, and a fixing block 56. The left side of the stirring frame 32 is connected to three fixed frames 52 from top to bottom. There are three stirring frames 51, which are rotatably connected to the fixed frames 52. There are three torsion springs 53, which are connected between the left side of the stirring frame 51 and the right side of the fixed frame 52. The torsion springs 53 are all wound around the left side of the stirring frame 51. There are three pull ropes 54, which are wound around the right side of the stirring frame 51. The pulling frame 55 is slidably connected to the right rear of the stirring frame 32. The rear side of the pull ropes 54 is connected to the pulling frame 55. There are four fixing blocks 56, which are connected to the inner wall of the iron pot 2 along the circumferential direction. The fixing blocks 56 are pressed and engaged with the right side of the pulling frame 55.

[0048] When the stirring rack 32 rotates counterclockwise, it also drives the turning rack 51, the fixed rack 52, and the pulling rack 55 to rotate counterclockwise. When the pulling rack 55 rotates counterclockwise and comes into contact with the fixed block 56, the fixed block 56 will push the pulling rack 55 upward and then pull the pull rope 54, causing the pull rope 54 to pull the turning rack 51 to rotate. The torsion spring 53 is twisted. When the pulling rack 55 moves away from the fixed block 56, it will move downward under its own weight and will no longer pull the pull rope 54. At this time, under the action of the torsion spring 53, the turning rack 51 will reverse and rewind the pull rope 54. In summary, the turning rack 51 can continuously rotate forward and backward, so that the turning rack 51 continuously turns the clean river sand and medicinal materials up and down, which is beneficial for the processing of medicinal materials and makes the medicinal materials more evenly heated during the processing.

[0049] like Figure 1 , Figure 2 , Figure 12 and Figure 13 As shown, it also includes a suction mechanism 6, which includes a gas storage tank 61, a piston rod 62, a return spring 63, a connecting pipe 64, and a squeezing block 65. The gas storage tank 61 is connected to the lower left wall of the oven 1. The gas storage tank 61 is equipped with a one-way valve, which can prevent the gas in the gas storage tank 61 from flowing back out. The connecting pipe 64 is fixed to the lower right side of the gas storage tank 61 and is connected to the gas storage tank 61. The left side of the connecting pipe 64 is connected to the lower right side of the heat conduction pipe 41. The piston rod 62 is slidably connected to the gas storage tank 61. The left side of the piston rod 62 slides out of the left side of the oven 1. The push-pull frame 66 is fixed to the left side of the piston rod 62. The return spring 63 is connected between the lower right side of the push-pull frame 66 and the left side of the oven 1. The return spring 63 is wound around the piston rod 62. The top left side of the stirring rack 32 is connected to the squeezing block 65, which is squeezed and engaged with the upper right side of the push-pull frame 66.

[0050] When it is necessary to accelerate the rate at which heat enters the heat pipe 41 within the baking oven 1, the suction mechanism 6 can be used. When the stirring rack 32 rotates counterclockwise, it also drives the extrusion block 65 to rotate counterclockwise. When the extrusion block 65 rotates to contact the upper right part of the push-pull frame 66, it will push the push-pull frame 66 to the left, stretching the return spring 63. The push-pull frame 66 moves to the left, causing the piston rod 62 to move to the left. At this time, the piston rod 62 will draw heat into the baking oven 1 through the air storage tank 61, thus increasing the heat inside the baking oven 1. Heat is drawn into the gas storage tank 61. When the extrusion block 65 rotates away from the upper right part of the push-pull frame 66, the push-pull frame 66 drives the piston rod 62 to move to the right under the action of the return spring 63. Since the one-way valve on the gas storage tank 61 will prevent the drawn-in gas from being discharged to the right, the movement of the piston rod 62 to the right can squeeze the hot gas inside the gas storage tank 61 into the heat conduction pipe 41 through the connecting pipe 64. This can accelerate the speed at which heat enters the heat conduction pipe 41, thereby accelerating the heating speed of the stirring rack 32 and improving the efficiency of the stirring rack 32 in heating the central medicinal materials.

[0051] like Figure 2 , Figure 14 and Figure 15 As shown, it also includes a venting mechanism 7, which includes a venting frame 71, a connecting spring 72, and a sealing cover 73. The upper left part of the stirring frame 32 has a venting port. The venting frame 71 is fixedly connected to the venting port of the stirring frame 32. The sealing cover 73 is slidably connected to the upper part of the venting frame 71. The connecting spring 72 is connected between the upper right part of the sealing cover 73 and the upper left part of the venting frame 71.

[0052] When the mixing rack 32 is filled with gas and heat can no longer be supplied to it, the gas can be discharged through the venting mechanism 7. First, pull the sealing cover 73 to the left, no longer blocking the upper part of the venting frame 71. Then, the connecting spring 72 is stretched, and the gas in the mixing rack 32 will be discharged outward through the vent and the venting frame 71. Then, heat can be supplied to the mixing rack 32 again. After the gas in the mixing rack 32 is discharged, loosen the sealing cover 73. Under the action of the connecting spring 72, the sealing cover 73 moves back to the right to reset and block the upper part of the venting frame 71 again. In summary, the gas inside the mixing rack 32 can be discharged, making it easier for people to supply heat to the mixing rack 32 next time.

[0053] like Figure 2 and Figure 16 As shown, it also includes a scraping mechanism 8, which includes a scraping frame 81 and a compression spring 82. The scraping frame 81 is slidably connected to the lower right front side of the stirring frame 32. The scraping frame 81 is in contact with the inner bottom wall of the iron pot 2. The compression spring 82 is connected between the upper part of the scraping frame 81 and the stirring frame 32.

[0054] When the bottom of the iron pot 2 becomes sticky after a period of use, some medicinal materials may also stick during the subsequent processing. In this case, the scraping mechanism 8 can be used to scrape the medicinal materials off. When the stirring rack 32 rotates, it also drives the scraping rack 81 to rotate. The rotation of the scraping rack 81 can scrape off the medicinal materials stuck to the bottom of the iron pot 2, preventing the medicinal materials from burning and improving the processing effect. At the same time, under the action of the compression spring 82, the scraping rack 81 can always be in contact with the bottom of the iron pot 2, and the scraping rack 81 will not scratch the bottom of the iron pot 2. In summary, the medicinal materials stuck to the bottom of the iron pot 2 can be scraped off, preventing the medicinal materials from sticking to the bottom of the iron pot 2, and making the processing effect of the medicinal materials better.

[0057] S1: First, put the clean river sand into the iron pot 2, then turn on the baking machine 1 to heat the clean river sand in the iron pot 2. When the clean river sand reaches a suitable temperature, put the medicinal materials into the heated clean river sand.

[0058] S2: Turn on the motor 31 to drive the stirring rack 32 to stir-fry the clean river sand and medicinal materials. The heat in the baking machine 1 will also enter the stirring rack 32 through the heat pipe 41 and the air pipe 42 to assist the stirring rack 32 in heating the clean river sand and medicinal materials in the middle.

[0059] S3: When stir-frying clean river sand and medicinal materials, the stirring rack 51 will stir the clean river sand and medicinal materials from top to bottom to assist in the processing of medicinal materials;

[0060] S4: After the medicinal materials have been processed, turn off the baking machine 1 and the motor 31, and then take out the processed medicinal materials.
