Description

Technical Field

[0001] This application relates to the field of pharmaceutical mixing equipment technology, and in particular to a hot mixing device for preparing black plaster. Background Technology

[0002] Black plaster refers to a paste made from medicinal herbs, vegetable oil, and litharge. In the preparation of black plaster, the medicinal herbs, vegetable oil, and litharge are added to the corresponding equipment. At the same time, the mixture is heated and stirred thoroughly during the boiling process to finally complete the preparation of black plaster.

[0003] For the equipment used to prepare black plaster, early open-type equipment without smoke purification function was used. Because a large amount of highly irritating and toxic fumes containing acrolein and propionamide were generated during the preparation process, workers needed to wear gas masks, but this still posed a certain degree of harm to the health of the workers. Therefore, the existing technology has been further improved by designing the preparation equipment as an integrated tank-type preparation vessel. In this way, the toxic gases generated during the preparation process can be collected and harmlessly treated.

[0004] However, the integrated tank design of the existing decoction equipment has two problems. First, because the stirring structure is relatively fixed in the tank and the equipment is large, it is difficult for workers to effectively clean the decoction chamber after decoction. In particular, there are blind spots that are difficult to clean, such as the stirring paddle structure and the bottom of the tank, which makes it difficult to meet GMP requirements. Second, the structural design of the decoction equipment lacks a pretreatment step before adding litharge. If litharge clumps or is unevenly distributed when added, it may lead to excessively high local concentrations, forming clumps that are not easy to disperse, thereby reducing the yield of the finished black plaster. Summary of the Invention

[0005] This application aims to propose a hot mixing device for the preparation of black plaster, in order to at least solve the technical problems in the prior art where it is difficult to effectively clean the cavity after boiling and the lack of a pretreatment structure before adding litharge leads to a reduction in the yield of finished black plaster.

[0008] In some embodiments, the dispensing assembly includes a medicine cover disposed on the cover body and a dispersing and sieving structure disposed within the medicine cover body; a portion of the medicine cover body extends through the cover body and is provided with a discharge port communicating with the mixing chamber; wherein, the medicine cover body is provided with a pulverizing chamber communicating with the discharge port, and the dispersing and sieving structure includes a first driving member disposed on the outer surface of the medicine cover body and a pulverizing rod connected to the output shaft of the first driving member and extending into the pulverizing chamber, the pulverizing rod being provided with a plurality of shearing blades circumferentially.

[0009] In some embodiments, a screen disk and a disturbance ring are sequentially fitted onto the end of the crushing rod away from the first driving member. The screen disk is rotatably connected to the crushing rod and has a first protrusion facing the surface edge of the disturbance ring. The disturbance ring is fixedly connected to the crushing rod and has a second protrusion facing the surface edge of the screen disk. When the disturbance ring rotates, the screen disk reciprocates along the axial direction of the crushing rod.

[0010] In some embodiments, the circumferential sidewall of the mesh screen extends to fit against the inner sidewall of the medicine cover, and an elastic reset member is provided at the edge of the top surface of the mesh screen, the other end of which is fixedly connected to the medicine cover.

[0011] In some embodiments, a second driving member is provided on the rotating support, and the output shaft of the second driving member is connected to the stirring structure via a pulley.

[0012] In some embodiments, a reciprocating screw is provided on the surface of the support plate near the medicine cover. One end of the reciprocating screw is connected to the second driving member via a pulley. The other end of the reciprocating screw is connected to a gate adapted to the discharge port. When the reciprocating screw rotates, the gate periodically closes the discharge port.

[0013] In some embodiments, the stirring structure includes a first stirring rod and a second stirring rod arranged at an angle to the first stirring rod, wherein the first stirring rod and the second stirring rod are respectively provided with stirring paddles at the ends away from the support plate.

[0014] In some embodiments, a temperature sensor is provided on the surface of the first stirring rod or the second stirring rod near the stirring paddle.

[0015] In some embodiments, a gear is coaxially arranged on the rotating shaft connecting the rotating bracket and the support base, a telescopic motor is arranged on the surface of the support base, and the output shaft of the telescopic motor is connected to a rack that linearly meshes with the gear.

[0016] Compared with the prior art, the technical solution provided in the first aspect of this application has at least the following beneficial effects or advantages: The mixing device provided in this application features a pot body rotatably connected to a support base. A worm gear is installed at the rotatable connection between the pot body and the support base, allowing the pot body to tilt and return to its original position by rotating the worm gear. This facilitates the transfer of the mixed black plaster from the pot body. The device includes a rotating support and a stirring assembly. The stirring assembly comprises a lid adapted to the pot body and a stirring structure rotatably connected to the support plate and located between the lid and the pot body. After mixing and cooking, the rotating support is controlled to completely remove the lid and stirring structure from the pot cavity, eliminating blind spots for cleaning. After cooking, it allows for efficient cleaning of the stirring structure and pot body by workers to meet GMP requirements. Furthermore, when the lid is closed on the pot body, a relatively sealed mixing chamber is formed, allowing for centralized treatment of the generated fumes and preventing overflow. The addition of a lead oxide addition assembly eliminates the need for manual addition of lead oxide. The lead oxide addition assembly also includes a dispersing and sieving structure that further breaks down and disperses the lead oxide to be added, effectively preventing uneven addition and improving the yield of the finished black plaster.

Detailed Implementation

[0021] The embodiments of this application are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] In the process of boiling black ointment, a large amount of highly irritating and toxic fumes containing acrolein and propionamide are generated. Therefore, existing equipment for preparing black ointment often uses a tank-type design, with the stirring structure installed inside the tank for thorough mixing. This stirring structure is not detachable from the tank during daily use. Furthermore, to improve the tank's airtightness, the opening is very small. The inventor discovered that while this design allows for the centralized discharge and treatment of the fumes, ensuring the safety and health of operators, the fact that the stirring structure is inside the tank... The location of the equipment is relatively fixed and the equipment is large in size. After the boiling process is completed, it is difficult for the staff to effectively clean the boiling chamber inside the tank. In particular, there are blind spots that are difficult to clean, such as the stirring paddle structure and the bottom of the tank, which makes it difficult to meet GMP requirements. At the same time, the structural design of the boiling equipment lacks a pretreatment step before adding litharge. If litharge clumps or is unevenly distributed when added, the stirring structure cannot disperse the litharge because it needs to be stirred with oily raw materials. This results in localized high concentrations and the formation of clumps that are difficult to disperse, thereby reducing the yield of the finished black plaster.

[0025] Based on this, the inventors proposed a hot mixing device for preparing black plaster oil to solve the aforementioned technical problems.

[0026] Please see Figures 1 to 2 This embodiment provides a hot mixing device for preparing black plaster oil. The mixing device 100 includes a support base 10, a pot body 20, a rotating bracket 30, a stirring assembly 40, and a cadmium dispensing assembly 50. For ease of description, the length direction of the support base 10 is defined as the first direction A, and the width direction of the support base 10 is defined as the second direction B. The support base 10 can be composed of a bottom plate and two spaced side plates, with a receiving space 11 formed between the two side plates that runs through the first direction A. The receiving space 11 is used to avoid interference with the pot body 20 during rotation. Of course, the support base 10 can also be other structures, such as replacing the side plates with support rods. No specific limitation is made here.

[0027] Furthermore, the pot body 20 is disposed in the receiving space 11 and rotatably connected to the support base 10, wherein the rotating shaft is distributed along the first direction A, that is, the pot body 20 can rotate in the second direction B. The rotating bracket 30 is rotatably connected to the support base 10 and can rotate toward or away from the pot body. The stirring assembly 40 is disposed at the end of the rotating bracket 30 away from the support base 10, wherein when the rotating bracket 30 rotates toward the pot body 20, the stirring assembly 40 can at least partially extend into the pot body 20 for stirring the hot mixing of the cinnabar and oil. The cinnabar feeding assembly 50 is disposed on the support base 10 and is used to sieve the cinnabar powder and feed the cinnabar powder into the pot.

[0028] Specifically, the pot body 20 can be provided with a hemispherical mixing chamber with the opening facing upwards. A hydraulic cylinder 33 is provided at the connection between the rotating bracket 30 and the support base 10. The rotation of the rotating bracket 30 is controlled by controlling the extension and retraction of the output end of the hydraulic cylinder 33. Since a stirring component 40 is provided at the end of the rotating bracket 30 away from the support base 10, the rotation of the rotating bracket 30 causes the stirring component 40 to rotate synchronously toward or away from the pot body 20. During the black ointment cooking process, one end of the stirring blade of the stirring component 40 extends into the mixing chamber of the pot body 20 to stir during the cooking process. After cooking is completed, the stirring component 40 is lifted upwards by the rotating bracket 30, that is, the stirring component 40 is separated from the mixing chamber, which facilitates the cleaning of the pot body 20 and the stirring component 40.

[0029] The powder feeding assembly 50 is located on one side of the support base 10. The powder feeding assembly 50 may include a powder sieving structure and a quantitative feeding structure. The powder sieving structure may consist of multiple layers of screens and a vibration structure. The quantitative feeding structure may include a rotating shaft that is rotatably connected to the support base 10. When it is necessary to feed powder into the pot, the powder feeding assembly 50 is rotated so that the hopper of the powder feeding assembly 50 moves above the pot body 20, thereby adding the powder.

[0030] It should be noted that the rotation of the pot body 20 can be controlled by a motor. In order to automatically control the entire mixing device 100, a control panel 60 can also be set on the side of the support base 10. The control panel 60 has an oil temperature display and a stirring speed display window. At the same time, the control panel 60 can also be equipped with a vibration switch to control the sieving of the powder by the powder feeding assembly 50. In addition, the control panel 60 can also be equipped with an arm raising switch, an arm lowering switch, a discharge switch and a reset switch to control the rotation of the pot body 20 and the rotating support 30.

[0031] In this embodiment, the mixing device 100 is rotatably connected to the pot body 20 on the support base 10, which facilitates the transfer of the mixed black plaster from the pot body 20. With the rotating bracket 30 and the stirring assembly 40, one end of the stirring blades of the stirring assembly 40 can extend into the pot body 20. After the black plaster is mixed and cooked, the rotating bracket 30 is controlled to rotate, and after cooking is complete, the stirring assembly 40 is completely transferred out of the pot body 20 cavity, thus eliminating blind spots for cleaning and facilitating effective cleaning of the stirring assembly 40 and the pot body 20 by staff to meet GMP requirements. With the addition of the powder-feeding assembly 50, manual powder feeding is not required. Furthermore, the powder-feeding assembly 50 can further vibrate and sieve the powder, resulting in more uniform feeding and improving the yield of the finished black plaster.

[0032] Meanwhile, the mixing device 100 in this embodiment can also continuously collect the temperature change curve inside the pot during the black ointment boiling process. Specifically, through the built-in dual high-precision temperature control devices on the jacket and stirring paddle, precise temperature control can be achieved. Since the temperature of adding the elixir is a key parameter, if the temperature is too low, the reaction of the elixir oil will not be complete, and if the temperature is too high, it will be easy to catch fire. Through precise temperature sensors and recorders, the temperature curve is recorded throughout the process, which facilitates process supervision and traceability.

[0033] Please see Figures 3 to 6This embodiment provides an improved hot mixing device for preparing black plaster oil based on the above embodiments. The mixing device includes a support base 10, a pot body 20, a rotating bracket 30, a stirring assembly 40, and a cadmium-feeding assembly 50. For ease of description, the length direction of the support base 10 is defined as the first direction A, and the width direction of the support base 10 is defined as the second direction B. The support base 10 can be composed of a bottom plate and two spaced side plates, with a receiving space 11 formed between the two side plates that runs through the first direction A. The receiving space 11 is used to avoid interference with the pot body 20 during rotation. Of course, the support base 10 can also be other structures, such as replacing the side plates with support rods. No specific limitation is made here.

[0034] Furthermore, the pot body 20 is disposed in the receiving space 11 and rotatably connected to the support base 10. A turbine 11 is coaxially mounted on the rotating shaft connecting the pot body 20 and the support base 10, and a worm gear 12 meshing with the turbine 11 is mounted on the support base 10. A rotating bracket 30 is rotatably connected to the support base 10, and a support column 31 and a support plate 32 connected to one end of the support column 31 and extending toward the pot body 20 are mounted on the rotating bracket 30. The stirring assembly 40 includes components disposed on the support plate 32 away from the support column 31. The 1-end is a cover 41 adapted to the pot body 20, and a stirring structure 42 is rotatably connected to the support plate 32 and located between the cover 41 and the pot body 20. When the rotating support 30 rotates, the cover 41 can be selectively placed on the pot body 20 to form a closed mixing chamber. The 1-end assembly 50 includes a medicine cover 51 disposed on the cover 41 and a dispersing and screening structure 52 disposed inside the medicine cover 51. A portion of the medicine cover 51 penetrates the cover 41 and is provided with a discharge port 511 communicating with the mixing chamber.

[0035] It should be noted that the pot body 20 may be provided with a hemispherical mixing chamber 21, the opening of which faces upward. By rotating the rotating support 30, the stirring assembly 40 can be rotated along the axis of the rotating support 30, so that the lid 41 and the stirring assembly 40 rotate synchronously toward or away from the pot body 20. The lead-adding assembly 50 is used to control the addition of lead oxide into the pot body 20. Specifically, before the black plaster is boiled, by controlling the rotating support 30 to rotate in a direction away from the pot body 20, the lid 41 and the stirring structure 42 rotate away from the pot body 20. The ingredients are separated in the pot 20. After being separated to a preset position, the medicinal materials and vegetable oil are added into the pot 20 and preheated by the electric heating rod 22. Then, the rotating support 30 is controlled to rotate towards the pot 20, so that the stirring structure 42 extends into the mixing chamber 21. Simultaneously, the pot lid 41 can just close the opening at the top of the pot 20, so that the mixing chamber 21 is in a sealed state. Then, the boiling and stirring mixing process is carried out. The generated fumes can be discharged from the exhaust pipe 411 set on the lid 41 for centralized treatment, thereby avoiding harm to the health of the operators.

[0036] It should also be noted that after the black plaster is cooked, the rotating support 30 is rotated at a certain angle away from the pot body 20 to separate the stirring component 40 from the black plaster. After a large amount of black plaster remaining on the stirring structure 42 falls into the pot body 20, the rotating support 30 is rotated away from the pot body 20 until the pot body 20 does not interfere with the stirring structure 42 and the cover 41 during the rotation process. Then, the pot body 20 is rotated along the axis away from the rotating support 30, and a collection device is placed in front of the guide channel 211 set in the pot body 20 so that the black plaster flows from the guide channel 211 to the collection device, thereby completing the transfer of the black plaster from the pot body 20.

[0037] In this embodiment, the mixing device 100 rotatably connects a pot body 20 to a support base 10. A worm gear is installed at the rotatable connection between the pot body 20 and the support base 10. Rotating the worm gear 12 allows the pot body 20 to tilt and return to its original position, facilitating the transfer of the mixed black plaster from the pot body 20. The device also includes a rotating support 30 and a stirring assembly 40. The stirring assembly 40 includes a lid 41 adapted to the pot body 20 and a stirring structure 42 rotatably connected to a support plate 32 and located between the lid 41 and the pot body 20. After mixing and cooking, controlling the rotation of the rotating support 30 ensures that the lid 41 and the stirring structure 42 move smoothly and evenly. The mixing structure 42 is completely removed from the pot body 20 cavity, thereby eliminating cleaning blind spots and facilitating effective cleaning of the mixing structure 42 and the pot body 20 by staff to meet GMP requirements. At the same time, when the cover 41 is closed on the pot body 20, a relatively sealed mixing chamber 21 is formed, which allows the generated flue gas to be centrally treated to prevent overflow. With the setting of the lead-acid feeding component 50, manual lead feeding is not required. Furthermore, the dispersing and screening structure 52 set in the lead-acid feeding component 50 can further crush, disperse and screen the lead-acid to be added, thereby effectively avoiding uneven lead feeding and improving the yield of finished black plaster.

[0038] Optional, combined Figure 4 The pot body 20 can be provided with rotating shafts on both sides of the second direction B. At the same time, bearing seats 13 connected to the rotating shafts can be provided on both sides of the support base 10. Thus, since a turbine 11 is provided at one end of the rotating shaft extending out of the bearing seat 13, the worm gear 12 is provided along the first direction A on the side wall of the support base 10 and meshes with the turbine 11. The setting of the bearing seat 13 makes it convenient for the staff to tilt the pot body 20. In order to facilitate the control of the rotation of the worm gear 12, a rocker arm can be provided at one end of the worm gear 12. When the rocker arm is rotated clockwise or counterclockwise, the pot body 20 is controlled to rotate along its rotating shaft, thereby causing the pot body 20 to tilt or straighten in the first direction A.

[0039] Of course, the joystick can also be replaced with a motor for control. The specific choice can be made according to actual needs. An electric heating rod 22 is provided at the bottom of the pot body 20. The electric heating rod 22 at the bottom of the pot body 20 can be set as a disc. It can be understood that the electric heating rod 22 can be obtained from existing technology. Its structure and principle will not be described in detail here.

[0040] Please continue to combine Figure 5 A gear 301 is coaxially mounted on the rotating shaft connecting the rotating bracket 30 and the support base 10. A telescopic motor 13 is mounted on the surface of the support base 10. The output shaft of the telescopic motor 13 is connected to a rack 14 that meshes linearly with the gear 301. Specifically, the telescopic motor 13 and the rack 14 can be fixed by a support structure mounted on the bottom end face of the support. The output shaft of the telescopic motor 13 and the rack 14 are distributed along the first direction A. When the rack 14 moves horizontally back and forth in the first direction A, the rotating shaft of the rotating bracket 30 is controlled to rotate in the second direction B, thereby controlling the rotation of the rotating bracket 30.

[0041] In some embodiments, please refer to Figures 6 to 8 The medicine cover 51 is provided with a crushing chamber 512 communicating with the discharge port 511. A conveying pipe 513 is provided on the side wall of the medicine cover 512 at the crushing chamber 512. The conveying pipe 513 is used to input litharge into the crushing chamber 512. The dispersing and screening structure 52 includes a first driving member 521 provided on the outer surface of the medicine cover 51, and a crushing rod 522 connected to the output shaft of the first driving member 521 and extending into the crushing chamber 512. The crushing rod 522 is provided with a plurality of shearing blades 523 in a circumferential direction.

[0042] It should be noted that the first driving component 521 can be a servo motor, and multiple shearing blades 523 are distributed on its surface along the length of the crushing rod 522. One end of the shearing blade 523 is connected to the crushing rod 522, and the other end extends toward the wall of the medicine cover 51. With this setting, manual addition of lead oxide is no longer required, protecting the safety and health of the operator. When the lead oxide transported through the conveying pipe 513 falls into the crushing chamber 512, the shearing blades 523 can further break up the small pieces of lead oxide, making them into powder and adding them into the mixing chamber 21 of the cylinder. This avoids the addition of clumps of lead oxide into the mixing chamber 21, which would cause the local lead oxide concentration to be too high and form clumps that are not easy to disperse, thereby reducing the yield of the finished black plaster.

[0043] To further prevent lumpy litharge from entering the mixing chamber 21 within the pot body 20, a screen disk 524 and a disturbance ring 525 are sequentially fitted onto the end of the crushing rod 522 facing away from the first driving member 521. The screen disk 524 is rotatably connected to the crushing rod 522, and a first protrusion 5241 is provided facing the surface edge of the disturbance ring 525. The disturbance ring 525 is fixedly connected to the crushing rod 522, and a second protrusion 5251 is provided facing the surface edge of the screen disk 524. When the disturbance ring 525 rotates, the screen disk 524 reciprocates along the axial direction of the crushing rod 522.

[0044] Specifically, the first protrusion 5241 and the second protrusion 5251 can be set to have the same shape. For example, the shape of the first protrusion 5241 and the second protrusion 5251 can be set to semi-circular. The number of the first protrusion 5241 and the second protrusion 5251 can be set to four or six. There is no specific limitation here. When the crushing rod 522 rotates, it drives the disturbance ring 525 to rotate. Since the screen disk 524 is fixed to the medicine cover 51, the screen disk 524 and the disturbance ring 525 rotate relative to each other. When the first protrusion 5241 and the second protrusion 5251 collide, the screen disk 524 moves up and down back and forth, thereby realizing the screening of litharge and further preventing blocky litharge from falling into the mixing chamber 21 inside the pot body 20.

[0045] Optional, please continue reading Figure 6 The sieve disc 524 extends circumferentially to fit against the inner wall of the medicine cover 51, and an elastic reset member 5242 is provided on the edge of the top surface of the sieve disc 524. The other end of the elastic reset member 5242 is fixedly connected to the medicine cover 51. This design, where the sieve disc 524 extends circumferentially to fit against the inner wall of the medicine cover 51, prevents lumpy litharge from falling into the mixing chamber 21. Simultaneously, the sieve disc 524 also separates the crushing chamber 512 from the discharge port 511. The structure of the elastic reset member 5242 can be configured as follows: Similar to a hydraulic cylinder structure, a sleeve is set on the screen plate 524, and a spring is set inside the sleeve, so that the spring can only extend and retract within the sleeve. At the same time, one end of the spring is connected to the inner wall of the medicine cover 51 through a connecting rod. With this configuration, when the screen plate 524 moves up and down, the elastic reset member 5242 can provide additional force, making the screen plate 524 move up and down faster, preventing litharge from clogging the screen plate 524, and also allowing the blocky litharge to be broken up again by the shear blades 523.

[0046] It should be noted that the mesh size of the screen plate 524 can be selected according to actual needs. The crushing chamber 512 can be set as a cylindrical chamber, which facilitates the up and down movement of the screen plate 524. The discharge port 511 can be set as a funnel shape, which facilitates the falling of the sieved powdered lead into the mixing chamber 21.

[0047] In some embodiments, please refer to Figure 9 A second driving component 302 is provided on the rotating bracket 30. The second driving component 302 can be a motor. A through cavity can be provided inside the support column 31 along the central axis. The output shaft of the second driving component 302 can extend along the through cavity to the position of the support plate 32 and is provided with a first pulley 303. A second pulley 421 can be provided on the rotating shaft that is rotatably connected to the stirring mechanism 42 and the support plate 32. The first pulley 303 is connected to the second pulley 421 through the first transmission belt 304. With this configuration, the rotation control of the stirring mechanism 42 is realized, and the structure is made more integrated, thereby effectively avoiding interference between the stirring mechanism 42 and the pot body 20.

[0048] Please see Figure 10 and Figure 11 A reciprocating screw 321 is provided on the surface of the support plate 32 near the medicine cover 51. One end of the reciprocating screw 321 is connected to the second drive member 302 via a pulley. The other end of the reciprocating screw 321 is connected to a gate 322 adapted to the discharge port 511. When the reciprocating screw 321 rotates, the gate 322 periodically closes the discharge port 511. Specifically, a third pulley 422 is provided on the rotating shaft of the stirring structure 42. The third pulley 422 and the second pulley 421 are parallel and coaxial along the length of the rotating shaft. A fourth pulley 323 is provided on the upper end of the reciprocating screw 321. The third pulley 422 and the fourth pulley 323 are connected via a second transmission belt 324. The other end of the reciprocating screw 321 is connected to the gate 322 adapted to the discharge port 511 of the medicine cover 51. When the second drive member 302 runs, it synchronously drives the stirring structure 42 and the reciprocating screw 321.

[0049] Thus, by setting the reciprocating screw 321 to operate, the gate 322 is controlled to periodically close and close the discharge port 511, that is, the discharge of the discharge port 511 is periodically controlled. In this way, when making black plaster, the powder can be added periodically while stirring, so that the powder is added more evenly. This avoids adding too much yellow powder to the same position during the mixing process in the mixing chamber 21, which would lead to uneven distribution. This improves the yield of the finished black plaster and even avoids the generation of a large amount of smoke.

[0050] It should be noted that the reciprocating screw 321 can be obtained from existing technology, and its specific structure and functional principle will not be elaborated here. The gate 322 can be set into a frustum shape, which is compatible with the shape of the discharge port 511.

[0051] In some embodiments, continue reading Figure 11The stirring structure 42 includes a first stirring rod 423 and a second stirring rod 424 arranged at an angle to the first stirring rod 423. The first stirring rod 423 and the second stirring rod 424 are respectively provided with stirring paddles 425 at the ends away from the support plate 32. A temperature sensor 426 is provided on the surface of the first stirring rod 423 or the second stirring rod 424 near the stirring paddle 425.

[0052] It should be noted that the bottom of the stirring paddle 425 can be set to be arc-shaped, so that the stirring paddle 425 can be close to the wall of the mixing chamber 21 inside the pot 20 when stirring, thereby effectively avoiding the phenomenon of the mixed medicinal materials sticking to the bottom. The included angle between the first stirring rod 423 and the second stirring rod 424 can be 10°, 25° or 30°, and the specific design can be selected according to the actual needs.

[0053] In this embodiment, the first stirring rod 423 and the angled arrangement with the first stirring rod 423 make the stirring process more uniform and thorough. At the same time, it also facilitates the cleaning of the equipment. Especially after production, the stirring structure 42 can be rotated up and the pot body 20 tilted to facilitate further cleaning, thereby meeting GMP requirements. With the setting of temperature sensor 426, the temperature sensor 426 can directly collect the temperature of the black ointment semi-finished product in the mixing chamber 21, realize the recording of the temperature curve throughout the process, and facilitate process supervision and traceability.
