It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a Chinese medicine calcining furnace. Figure 1-3As shown, the Chinese medicine calcining furnace comprises: a fixed seat 1, a fixed door is hingedly installed on one side of the fixed seat 1; a calcining furnace 2, the calcining furnace 2 is placed on the fixed seat 1; a heating plate 3, the heating plate 3 is fixedly installed on the inner wall of the calcining furnace 2; a closing cover 4, the closing cover 4 can be arranged on the calcining furnace 2; a scraping mechanism, the scraping mechanism is arranged on the closing cover 4, the scraping mechanism is composed of a plurality of scrapers 5, the scrapers 5 can extend into the calcining furnace 2 and can slide in contact with the side wall of the calcining furnace 2; a turning mechanism , the turning mechanism is arranged on the closing cover 4, and the turning mechanism is composed of a plurality of flip plates 6, and the flip plates 6 can extend into the calcining furnace 2, and the flip plate 6 located at the bottom can contact the bottom inner wall of the calcining furnace 2; the driving mechanism, the driving mechanism is arranged on the closing cover 4, and the driving mechanism is used to drive the scraping mechanism and the turning mechanism to turn the Chinese medicinal materials; the reversing mechanism, the reversing mechanism is arranged on the closing cover 4, and the reversing mechanism is used to drive the scraping mechanism and the turning mechanism to rotate in opposite directions.

[0023] In this embodiment, the fixed base 1 serves as the support base of the entire calcining furnace 2, ensuring the stability and safety of the calcining furnace 2. A fixed door is installed on one side of the fixed base 1 to facilitate opening and closing the fixed base 1 and to facilitate stable fixing of the calcining furnace 2 on the fixed base 1.

[0024] The calcining furnace 2 is placed on the fixed base 1 and is the main container for calcining Chinese medicinal materials. It can withstand high temperatures and maintain the airtightness of the internal environment.

[0025] The heating plate 3 is fixedly mounted on the inner wall of the calcining furnace 2 and provides the temperature required for calcination by heating. It is the core heat source of the calcining process.

[0026] The closing cover 4 can be arranged on the calcining furnace 2 to close the furnace mouth to prevent heat loss and external impurities from entering, and at the same time serves as an installation platform for the scraping mechanism and the turning mechanism.

[0027] The scraping mechanism consists of several scrapers 5 that extend into the calcining furnace 2 and slide against the side walls. They are used to scrape the medicinal materials near the furnace wall to prevent them from burning or uneven calcination due to uneven heating. This ensures that the medicinal materials near the furnace wall are fully turned and evenly heated, thereby improving the quality of the calcined medicine.

[0028] The turning mechanism consists of several turning plates 6 that extend into the calcining furnace 2. The lowest turning plate 6 contacts the furnace bottom and turns the medicinal materials at the bottom, causing the upper layers to fall, thus turning the entire material. This ensures comprehensive turning of the Chinese medicinal materials, preventing local overheating or incomplete calcination, and improving calcination uniformity and efficiency.

[0029] The driving mechanism is provided on the closing cover 4 and is used to drive the scraping mechanism and the turning mechanism to work together to effectively turn the Chinese medicinal materials. The turning process is automatically controlled, reducing the burden of manual operation and improving production efficiency and consistency.

[0030] The reversing mechanism is provided on the closing cover 4, and is used to drive the scraping mechanism and the turning mechanism to rotate in opposite directions, further promoting the uniform turning of the medicinal materials. By rotating in opposite directions, the stacked state of the medicinal materials is broken, the turning effect is increased, and the Chinese medicinal materials are heated more evenly.

[0031] In a further preferred embodiment of the present invention, the driving mechanism includes a driving rod 7 rotatably mounted on the closing cover 4, a driving motor 8 is fixedly mounted on the closing cover 4, the output shaft of the driving motor 8 is fixedly connected to the driving rod 7, a plurality of flip rods 9 are rotatably mounted on the driving rod 7, and the flip plate 6 is fixedly connected to the flip rod 9.

[0032] In this embodiment, the drive rod 7 is rotatably mounted on the closure cover 4 and serves as a transmission component, transmitting the power of the drive motor 8 to the material turning mechanism and the scraping mechanism. As the core component of power transmission, it ensures that power can be smoothly and effectively transmitted to the material turning mechanism and the scraping mechanism, realizing their coordinated operation.

[0033] Drive motor 8, fixedly mounted on closure lid 4, is the power source for the drive mechanism. Its output shaft is fixedly connected to drive rod 7, providing the necessary power for the entire turning process. This enables automated control of the turning and scraping mechanisms, reducing the burden of manual operation and improving production efficiency and consistency. Furthermore, precise motor control ensures a more uniform and effective turning effect.

[0034] The turning lever 9 is rotatably mounted on the driving rod 7 and serves as an intermediate component connecting the driving rod 7 and the flap 6. The turning movement of the flap 6 is driven by the rotation of the driving rod 7. The ingenious design of the turning lever 9 effectively transmits power from the driving rod 7 to the flap 6, allowing the flap 6 to flip along a predetermined trajectory, thereby achieving a comprehensive flipping effect on the Chinese medicinal materials.

[0035] The flap 6 is fixedly connected to the tilting rod 9 and is the component that actually performs the tilting action. The back-and-forth movement of the flap 6 ensures the complete rotation of the Chinese medicinal materials within the calcining furnace 2. This rotation of the flap 6 effectively prevents localized overheating or incomplete calcination of the Chinese medicinal materials, improving the uniformity and efficiency of the calcination.

[0036] In a further preferred embodiment of the present utility model, the reversing mechanism includes a driving gear ring 10 fixedly mounted on the driving rod 7, and a connecting plate 11 is fixedly mounted on both sides of the closing cover 4, and a driving gear 12 and a driven gear 13 are rotatably mounted on the two connecting plates 11, respectively. The driving gear 12 is engaged with the driving gear ring 10, and the driven gear 13 is engaged with the driving gear 12. A driven gear ring 14 is rotatably mounted on the driving rod 7, and the driven gear ring 14 is engaged with the driven gear 13. A fixing plate 17 is fixedly mounted on the bottom of the driven gear ring 14, and the top of the scraper 5 is fixedly connected to the fixing plate 17.

[0037] In this embodiment, the active gear ring 10 is fixedly mounted on the drive rod 7 and serves as the power input component of the reversing mechanism. It meshes with the active gear 12 and transmits the rotational power of the drive rod 7 to the active gear 12. The meshing of the active gear ring 10 and the active gear 12 achieves power transmission and direction conversion, providing the basis for the reversal of the scraping mechanism and the turning mechanism.

[0038] The connecting plate 11 is fixedly mounted on both sides of the closing cover 4 as a supporting and fixing member for mounting the driving gear 12 and the driven gear 13. The stability and accuracy of the driving gear 12 and the driven gear 13 are ensured so that they can rotate according to a predetermined trajectory.

[0039] The driving gear 12 is rotatably mounted on the connecting plate 11 and meshes with the driving gear ring 10. It receives power from the driving rod 7 and transmits it to the driven gear 13. As an intermediate link in the power transmission, the driving gear 12 converts the rotational motion of the driving rod 7 into the rotational motion of the driven gear 13, realizing continuous power transmission.

[0040] The driven gear 13 is rotatably mounted on the other connecting plate 11, meshing with the driving gear 12 and receiving power from the driving gear 12. At the same time, it meshes with the driven gear ring 14 and transmits power to the driven gear ring 14. By meshing with the driving gear 12 and the driven gear ring 14, the driven gear 13 realizes the retransmission and direction change of power, providing a power source for the reverse rotation of the scraper mechanism.

[0041] The driven gear ring 14 is rotatably mounted on the drive rod 7 and meshes with the driven gear 13. It receives power from the driven gear 13 and drives the fixed plate 17 and the scraper 5 to rotate. As the power receiving component of the scraping mechanism, the rotation of the driven gear ring 14 directly drives the scraper 5 to reverse, achieving uniform turning of the Chinese medicinal materials.

[0042] The fixing plate 17 is fixedly mounted on the bottom of the driven gear ring 14, serving as a mounting platform for the scraper 5, connecting the scraper 5 to the driven gear ring 14. This ensures the stability and accuracy of the scraper 5, enabling it to rotate accordingly with the rotation of the driven gear ring 14, thereby achieving effective turning of the Chinese medicinal materials.

[0043] Scraper 5 is fixedly connected to fixed plate 17 and is the component that actually performs the scraping action. It extends into the calcining furnace 2 and slides against the sidewalls. This scraping action effectively prevents the accumulation of Chinese medicinal materials near the furnace walls and uneven heating, thereby improving the uniformity and quality of the calcined materials. Furthermore, thanks to the reversing mechanism, scraper 5 can move in the opposite direction of the flipping mechanism, further enhancing the flipping effect.

[0044] In a further preferred embodiment of the present invention, multiple sets of fixed gear rings 15 are fixedly installed between several of the scrapers 5, and a driving gear 16 is fixedly installed on the side of the turning rod 9 close to the furnace wall of the calcining furnace 2, and the driving gear 16 is meshed with the fixed gear ring 15.

[0045] In this embodiment, fixed tooth rings 15 are fixedly installed between several scrapers 5 to form multiple connection structures. These fixed tooth rings 15 not only enhance the connection strength between the scrapers 5, but also act as transmission components to mesh with the drive gear 16.

[0046] The design of the fixed gear ring 15 ensures the stability of the scraping mechanism when turning the Chinese medicinal materials. At the same time, the engagement of the fixed gear ring 15 with the driving gear 16 provides another way for the power transmission of the scraping mechanism, thereby enhancing the linkage effect between the turning mechanism and the scraping mechanism.

[0047] The driving gear 16 is fixedly mounted on the side of the turning rod 9 close to the wall of the calciner 2 and meshes with the fixed gear ring 15. As part of the turning mechanism, the turning rod 9 is driven by the driving rod 7 to rotate in the calciner 2. The driving gear 16 on the turning rod 9 can rotate along the fixed gear ring 15, thereby driving the turning rod 9 to rotate on its own, so that the flap 6 can turn the Chinese medicinal materials in the calciner 2 up and down, improving the uniformity of heating.

[0048] The design of the drive gear 16 enables power transmission and linkage between the turning and scraping mechanisms. When the scraping mechanism is operating, the drive gear 16 rolls along the fixed gear ring 15, thereby driving the flap 6 to rotate, achieving full rotation of the Chinese medicinal materials. This design not only improves the uniformity of the calcined materials but also simplifies the mechanical structure and reduces manufacturing costs.

[0049] In a further preferred embodiment of the present invention, a telescopic cylinder 18 is fixedly installed on one side of the fixing base 1, a telescopic rod 19 is provided in the telescopic cylinder 18, and a mounting plate 20 is fixedly installed on one side of the telescopic rod 19 extending outside the telescopic cylinder 18, and one side of the mounting plate 20 is fixedly connected to the closing cover 4.

[0050] In this embodiment, the telescopic cylinder 18 is fixedly mounted on one side of the fixing base 1 and serves as a supporting and adjusting component. The telescopic cylinder 18 allows the telescopic rod 19 to slide inside the telescopic cylinder 18.

[0051] The telescopic cylinder 18 provides stable support and guidance for the telescopic rod 19, ensuring the stability and accuracy of the telescopic rod 19 during movement. At the same time, the design of the telescopic cylinder 18 allows the height of the closing cover 4 to be adjusted as needed, thereby enhancing the flexibility and adaptability of the calcining furnace 2.

[0052] The telescopic rod 19 is arranged in the telescopic cylinder 18 and extends to one side outside the telescopic cylinder 18. The extended end of the telescopic rod 19 is fixedly mounted with a mounting plate 20 for connecting and supporting the closing cover 4.

[0053] The telescopic rod 19 is a key component connecting the telescopic cylinder 18 and the mounting plate 20. Its telescopic function enables the lifting and lowering of the closing cover 4. This design allows the operator to conveniently adjust the distance between the closing cover 4 and the calcining furnace 2 according to the needs of the calcining process, thereby conveniently controlling the opening and closing of the calcining furnace 2.

[0054] The mounting plate 20 is fixedly mounted on a side of the telescopic rod 19 extending outside the telescopic cylinder 18, and one side thereof is fixedly connected to the closing cover 4. The mounting plate 20 serves as a connecting component to convert the telescopic motion of the telescopic rod 19 into the lifting motion of the closing cover 4.

[0055] The design of the mounting plate 20 ensures that the closure cover 4 can be securely mounted on the telescopic rod 19 and adjusted accordingly. This connection method is not only simple and reliable, but also effectively transmits the force of the telescopic rod 19, allowing the closure cover 4 to be raised and lowered smoothly, avoiding problems such as shaking or deviation.

[0056] In a further preferred embodiment of the present invention, a threaded sleeve 21 is rotatably mounted on the top of the telescopic cylinder 18, the telescopic rod 19 extends into the threaded sleeve 21 and is threadedly connected to the threaded sleeve 21, and a telescopic motor 22 is fixedly mounted on one side of the telescopic cylinder 18, and a pulley 23 is fixedly mounted on the output shaft of the telescopic motor 22 and the threaded sleeve 21, and the two pulleys 23 are provided with the same synchronous belt 24.

[0057] In this embodiment, the threaded sleeve 21 is rotatably mounted on the top of the telescopic cylinder 18, serving as a threaded connection component for the telescopic rod 19. The threaded sleeve 21 is internally provided with a thread matching the telescopic rod 19, and the telescopic adjustment of the telescopic rod 19 can be achieved by rotating it.

[0058] The design of the threaded sleeve 21 makes the telescopic rod 19 more precise and reliable in its telescopic adjustment. By rotating the threaded sleeve 21, the extension length of the telescopic rod 19 can be gradually adjusted, thereby achieving fine adjustment of the height of the closure cover 4. This adjustment method is not only simple and easy, but also effectively prevents the telescopic rod 19 from shaking or shifting during the extension and retraction process.

[0059] The telescopic rod 19 extends into the threaded sleeve 21 and is threadedly connected to the threaded sleeve 21. The connection mode of the telescopic rod 19 enables it to perform telescopic movement under the rotation of the threaded sleeve 21.

[0060] The threaded connection with the threaded sleeve 21 ensures the stability and accuracy of the telescopic rod 19 during the telescopic process. Simultaneously, this connection method also simplifies the mechanism structure, reduces manufacturing cost and maintenance difficulty.

[0061] The telescopic motor 22 is fixedly mounted on one side of the telescopic cylinder 18 as a driving component. The output shaft of the telescopic motor 22 is fixedly connected to the pulley 23 on the threaded sleeve 21. The telescopic motor 22 drives the threaded sleeve 21 through the transmission effect of the pulley 23 and the synchronous belt 24.

[0062] The introduction of the telescopic motor 22 enables automated control of telescopic adjustment. The operator can automatically adjust the height of the closure cover 4 simply by controlling the start, stop, and direction of the telescopic motor 22. This automated control method not only improves work efficiency but also reduces the difficulty and errors of manual operation.

[0063] Belt pulley 23 is fixedly mounted on the output shaft of telescopic motor 22 and threaded sleeve 21 respectively. Two belt pulleys 23 are provided with same synchronous belt 24, and the transmission effect of synchronous belt 24 realizes the driving of telescopic motor 22 to threaded sleeve 21.

[0064] The transmission mode of the pulley 23 and the synchronous belt 24 has the advantages of simple structure, stable transmission, low noise, etc. Through the transmission effect of the synchronous belt 24, the rotational motion of the telescopic motor 22 can be smoothly transmitted to the threaded sleeve 21, thereby realizing the telescopic adjustment of the telescopic rod 19.

[0065] A timing belt 24 is sleeved on the two pulleys 23 as a transmission component. The transmission function of the timing belt 24 enables the rotational motion of the telescopic motor 22 to be accurately transmitted to the threaded sleeve 21, thereby achieving accurate control of the telescopic rod 19.

[0066] The transmission mode of the synchronous belt 24 ensures the accuracy and stability of the telescopic adjustment. Through the transmission effect of the synchronous belt 24, the rotational motion of the telescopic motor 22 can be smoothly and non-slip transmitted to the threaded sleeve 21, thereby achieving accurate adjustment of the telescopic rod 19.

[0067] In a further preferred embodiment of the present invention, a guide groove 25 is provided on the inner wall of one side of the telescopic cylinder 18, and a guide block 26 is fixedly installed on one side of the telescopic rod 19. The guide block 26 extends into the guide groove 25 and slides in contact with the inner wall of the guide groove 25.

[0068] In this embodiment, a guide groove 25 is formed on the inner wall of the telescopic cylinder 18 to guide the telescopic rod 19 during its extension and retraction. The shape and size of the guide groove 25 match the guide block 26 to ensure that the guide block 26 can slide smoothly therein.

[0069] The guide slot 25 provides precise guidance for the telescopic movement of the telescopic rod 19, preventing any wobble or shifting of the telescopic rod 19 during the telescopic movement. This guidance not only improves the accuracy and stability of telescopic adjustment, but also extends the service life of the telescopic mechanism and reduces wear and malfunctions caused by wobble or shifting.

[0070] The guide block 26 is fixedly mounted on one side of the telescopic rod 19 and extends into the guide groove 25, slidingly contacting the inner wall of the guide groove 25. The shape and size of the guide block 26 match the guide groove 25 to ensure a close fit and smooth sliding between the two.

[0071] The sliding contact between the guide block 26 and the guide groove 25 ensures smooth movement of the telescopic rod 19 during extension and retraction. The design of the guide block 26 enables the telescopic rod 19 to precisely extend and retract along the trajectory of the guide groove 25 when driven by the rotational force of the threaded sleeve 21, without deviation or shaking. This design not only improves the precision and stability of telescopic adjustment, but also reduces noise and vibration, enhancing the overall user experience.

[0072] In summary, compared with the related art, by introducing automatic control elements such as the telescopic motor 22, the pulley 23, and the synchronous belt 24, the automatic adjustment of the height of the closing cover 4 is achieved, reducing the difficulty and error of manual operation.

[0073] The arrangement of the scraper 5 and the turning plate 6 allows the Chinese medicinal materials in the calcining furnace 2 to be turned more evenly, preventing the medicinal materials from piling up in one place for a long time and affecting the uniformity of heating. The reversing mechanism enables the scraper mechanism and the turning mechanism to move in opposite directions, further improving the fullness of the turning of the medicinal materials.

[0074] The combination of automatic control and precise adjustment makes the calcining furnace 2 more efficient and reliable during use, reducing production delays and losses caused by improper human operation or equipment failure.
