Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0026] Example:

[0027] See Figure 1 - Figure 4 This embodiment relates to a traditional Chinese medicine powder mixing and pelleting device, specifically used for mixing, forming strips, and pelleting traditional Chinese medicine powders. The device includes a main body, which comprises a stirring assembly 12, a strip-forming assembly 13, and a pellet-making assembly 14, all mounted and fixed on a housing 11.

[0028] The stirring assembly 12 includes a stirring chamber 15, which is located above the housing 11. A stirring rod 16 is vertically rotatably arranged inside the stirring chamber 15, and a stirring motor 17 for driving the stirring rod 16 to rotate is arranged at the top of the stirring chamber 15. The stirring chamber 15 is connected to the strip-making assembly 13 below. The feed inlet of the strip-making assembly 13 is located inside the housing 11, and its strip outlet 18 is located outside the housing 11.

[0029] The pelletizing assembly 14 includes a pelletizing box 21 disposed on one side of the box body 11. The pelletizing box 21 has an inlet 22 at the top and an outlet 23 at the bottom. The pelletizing box 21 is disposed below the outlet 18. Two sets of pressure rollers 24 are rotatably disposed inside the box. The pressure rollers 24 have semi-circular cross-section pressure grooves 25 on their outer periphery. The pressure grooves 25 of the two sets of pressure rollers 24 are correspondingly disposed.

[0030] The housing 11 is equipped with a drive motor 26, which is connected to two sets of pressure rollers 24 via a first transmission assembly 27.

[0031] Specifically, in this embodiment, pre-crushed and screened Chinese herbal powder and binder are added to the mixing chamber 15. The stirring motor 17 is started, driving the stirring rod 16 to rotate vertically. The stirring blades 19 on the stirring rod 16 continuously stir the powder, ensuring thorough mixing of all components. After stirring, the uniformly mixed powder enters the strip-making assembly 13 through a channel connected to the strip-making assembly 13 below the mixing chamber 15. The feed inlet of the strip-making assembly 13 is located inside the housing 11, and the outlet 18 is located outside the housing 11. The mixed material is extruded into strips and output from the outlet 18 to the pellet-making box 21. The extruded strips enter the pellet-making box 21 from the feed inlet 22. The two sets of pressure rollers 24 inside the pellet-making box 21 rotate, and the semi-circular cross-section pressure grooves 25 on the outer periphery of the two sets of pressure rollers 24 press the strips into uniform pellets, which are finally output from the pellet outlet 23 below the pellet-making box 21. This utility model integrates mixing, strip making, and pellet making through an integrated structural design. The material is continuously processed through the mixing chamber 15, the guide cylinder 51, and the pellet making box 21, which reduces dust pollution and loss of effective ingredients caused by manual transfer. Each unit can be operated by only one person, which is lower than the manual debugging and maintenance costs required by traditional three separate units.

[0032] In this embodiment, the first transmission component 27 includes a drive pulley 31 that is shaft-connected to the drive motor 26. A drive shaft 32 is rotatably mounted inside the housing 11. The drive pulley 31 is connected to a driven pulley 34 located at one end of the drive shaft 32 via a synchronous belt 33. A drive gear 35 is mounted at the other end of the drive shaft 32. The pressure roller 24 is shaft-connected to a driven gear 36 that meshes with the drive gear 35. The driven gear 36 is located on both sides of the drive gear 35, so that the two sets of pressure rollers 24 rotate in the same direction. The driven gears 36 connected to the two sets of pressure rollers 24 have different numbers of teeth to achieve different speeds. The two sets of pressure rollers 24 form a speed difference so that the medicine strips are kneaded in the pressure groove 25 to form pills.

[0033] The main body of the device also includes a support frame 41 located below the housing 11, and a set of movable wheels 42 is provided below the support frame 41. The support frame 41 adopts a welded frame structure of square steel tubes, and the four corners of the bottom are equipped with movable wheels 42. The movable wheels 42 are universal wheels with brake devices, which allows the device to move flexibly in the workshop and is easy to be deployed to the required production station.

[0034] The top of the mixing chamber 15 is also equipped with a liquid injection connector 43 that communicates with its interior for injecting binders such as honey, ethanol, and water. The mixing chamber 15 is equipped with a hopper 44, and a hinged flap 45 is attached to one side of the opening of the hopper 44. A handle 46 is provided on the upper surface of the flap 45. The hopper 44 is used to replenish the medicinal powder. The bottom of the hopper 44 is sloped to facilitate the sliding of the powder. The flap 45 is opened via the handle 46 for easy addition of the medicinal powder. After addition, the flap 45 must be closed to maintain a sealed environment inside the mixing chamber 15.

[0035] The strip-forming assembly 13 includes a guide cylinder 51, within which a guide screw 52 is rotatably mounted. The guide cylinder 51 is in communication with the bottom of the mixing chamber 15. The guide screw 52 is connected to the drive motor 26 via a second transmission assembly 53. The strip outlet 18 is located at one end of the guide cylinder 51 extending out of the housing 11. The guide cylinder 51 employs a heating sleeve to heat the mixture to maintain the viscosity of the medicinal material and ensure the extrusion and forming of the strip. The second transmission assembly 53 uses a chain drive mechanism 56, which includes a drive sprocket 54 shaft-connected to the drive motor 26 shaft. A driven sprocket 55 is located at the end of the guide screw 52, ​​and the drive sprocket 54 and the driven sprocket 55 are connected via a chain 56.

[0036] See Figure 3 The pelleting box 21 has a guide plate 61 on the side of the inlet 22 near the outlet 18. The guide plate 61 is angled downwards towards the inlet 22, and a baffle 62 is provided on the other side of the inlet 22. The guide plate 61 is inclined at an angle of 45°±15° relative to the upper surface of the pelleting box 21, so that the extruded drug strip falls into the inlet 22 along the guide plate 61. The baffle 62 on the corresponding side can prevent the drug strip from being thrown out of the inlet 22 when the pressure roller 24 rotates. The open design here allows the staff to observe the shape of the drug strip, adjust the ratio of adhesive and drug powder and the extrusion speed at any time, and also clean up the drug strips thrown out of the outlet 18 in a timely manner.

[0037] See Figure 4The pelleting box 21 has a square opening 63 on its rear side. Scrapers 64 are provided on the lower edge of the square opening 63 and the front side of the pellet outlet 23. Each scraper 64 has a scraper head 65 that fits snugly against the semi-circular contour groove 25 of the pressure roller 24. The scraper 64 is angled, and a separation plate 66 is provided at the pellet outlet 23. In this embodiment, the scraper 64 cleans the residual medicine material in the groove 25 of the pressure roller 24. The medicine material scraped off from the two sets of pressure rollers 24 is discharged from the square opening 63 and one side of the separation plate 66 at the pellet outlet 23, respectively. The other side of the separation plate 66 is used for normal output of finished pellets.

[0038] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
