Description

Technical Field

[0001] This utility model relates to the technical field of traditional Chinese medicine processing equipment, specifically to a traditional Chinese medicine ointment preparation equipment. Background Technology

[0002] Traditional Chinese medicine ointments are ointments made by adding appropriate excipients to corresponding drugs. Their medicinal properties are determined by the added drugs. They are widely used in the treatment of various diseases, and stirring is a particularly critical step in the ointment production process.

[0003] Existing traditional Chinese medicine ointment raw material mixing devices mostly employ a conventional mixing tank, mixing blades, and electric motor drive for mixing. Because the ointment is viscous, a large amount of it adheres to the inner wall of the mixing tank after mixing and flowing out of the outlet, resulting in waste. To solve this problem, some existing mixing devices add scrapers to the mixing shaft, which rotate with the shaft to scrape off the ointment adhering to the inner wall. However, in such devices, the scraper remains in constant contact with the inner wall of the tank during mixing, making it impossible to control the contact time. This not only increases the power consumption of the mixing motor but also shortens the scraper's lifespan due to continuous friction, presenting significant operational defects.

[0004] Therefore, we propose a device for preparing traditional Chinese medicine ointments. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] like Figures 1-8 As shown, this utility model discloses a traditional Chinese medicine ointment preparation device, including a tank 1, a drive mechanism 2, and a stirring mechanism 3. The stirring mechanism 3 is located inside the tank 1. The drive mechanism 2 includes a cylindrical shell 21 and a drive motor 22. The cylindrical shell 21 is fixedly installed on the top of the tank 1, and the drive motor 22 is fixedly installed on the top of the cylindrical shell 21. The stirring mechanism 3 includes a stirring shaft 31. The top end of the stirring shaft 31 is connected to the output shaft of the drive motor 22. A movable rod 33 is hinged on the stirring shaft 31, and a vertical rod 36 is hinged to the other end of the movable rod 33. A horizontal rod 34 is fixedly installed on the vertical rod 36, and a scraper 35 is fixedly connected to one end of the horizontal rod 34. The scraper 35 contacts the inner wall of the tank 1. An elastic component 32 is also fixedly connected to the stirring shaft 31. The elastic component 32 is slidably connected to the vertical rod 36. A horn-shaped cover 23 is provided inside the cylindrical shell 21, and an electric telescopic rod 24 is provided on the cylindrical shell 21. The electric telescopic rod 24 is connected to the horn-shaped cover 23, and the horn-shaped cover 23 compresses the elastic component 32.

[0032] Working principle: The elastic component 32 provides elastic support for the scraper 35, allowing the scraper 35 to adhere tightly to the inner wall of the tank 1. The up-and-down movement of the electric telescopic rod 24 and the horn-shaped cover 23 controls the extension and retraction of the elastic component 32. In conjunction with the rotation of the movable rod 33, the scraper 35 can be controlled to adhere to or separate from the inner wall of the tank 1, thereby controlling the scraping time of the scraper 35 against the inner wall of the tank 1.

[0033] like Figures 1-8 As shown, the elastic component 32 includes a sleeve 321, a push rod 322, and a spring 323. One end of the sleeve 321 is fixedly connected to the stirring shaft 31. A slider 324 is slidably adapted inside the sleeve 321. The push rod 322 slides through the other end of the sleeve 321, and one end of the push rod 322 is fixedly connected to the slider 324. The spring 323 is located inside the sleeve 321 and abuts against the slider 324 and the inner wall of the sleeve 321. A linear bearing 325 is fixedly connected to the end of the push rod 322 outside the sleeve 321. The vertical rod 36 slides through the linear bearing 325.

[0034] The working principle of the elastic component 32 is as follows: It provides elastic support for the scraper 35, allowing the scraper 35 to adhere tightly to the inner wall of the tank 1. The elastic component 32 can rotate with the stirring shaft 31. When the position between the scraper 35 and the inner wall of the tank 1 is adjusted, the linear bearing 325 will move closer to or further away from the stirring shaft 31. When the linear bearing 325 moves closer to the stirring shaft 31, the push rod 322 drives the slider 324 to compress the spring 323. At this time, with the rotation of the movable rod 33, the vertical rod 36 moves closer to the stirring shaft 31 along with the linear bearing 325 and moves upward along the linear bearing 325, thereby causing the scraper 35 to detach from the inner wall of the tank 1. When the linear bearing 325 moves away from the stirring shaft 31, under the rebound force of the spring 323, the vertical rod 36 moves away from the stirring shaft 31 along with the linear bearing 325. At this time, with the rotation of the movable rod 33, it moves downward along the linear bearing 325, thereby causing the scraper 35 to adhere to the inner wall of the tank 1.

[0035] like Figures 1-8 As shown, multiple limiting plates 231 are fixedly connected to the top edge of the horn-shaped cover 23. A sliding opening 232 is provided on the inner circumference of the cylindrical shell 21. The limiting plates 231 slide through the sliding opening 232. The electric telescopic rod 24 is fixedly connected to the top edge of the cylindrical shell 21. The output shaft of the electric telescopic rod 24 is fixedly connected to the limiting plate 231 that passes through the sliding opening 232. A bullseye bearing 326 is also fixedly installed on the side wall of the linear bearing 325 by a mounting rod. The balls on the bullseye bearing 326 roll in contact with the inner wall of the horn-shaped cover 23.

[0036] When the stirring shaft 31 rotates, it can drive the elastic component 32 to rotate inside the horn-shaped cover 23. Through the bullseye bearing 326, the elastic component 32 can roll against the inner wall of the horn-shaped cover 23. When the horn-shaped cover 23 moves up and down, it will not affect the rotation of the elastic component 32 when it is squeezed to extend and retract, thereby realizing the squeezing of the elastic component 32 during the stirring process, and thus realizing the position adjustment between the scraper 35 and the inner wall of the tank 1.

[0037] like Figures 1-8 As shown, the scraper 35 includes a vertical section 351 and an arc-shaped section 352. The vertical section 351 and the arc-shaped section 352 are integrally formed, and the vertical section 351 is fixedly connected to the horizontal rod 34. The arc-shaped section 352 is fixedly connected to the bottom end of the vertical rod 36. The arc-shaped section 352 of the scraper 35 contacts the bottom inner wall of the tank 1, and the vertical section 351 of the scraper 35 contacts the vertical inner wall of the tank 1.

[0038] The scraper 35 is processed into a vertical section 351 and an arc-shaped section 352 to make the scraper 35 contact the vertical inner wall and the arc-shaped bottom wall of the tank body 1, thereby increasing the scraping area of ​​the scraper 35 on the inner wall of the tank body 1.

[0039] like Figures 1-8 As shown, stirring blades 37 are also fixedly installed on the stirring shaft 31. The stirring blades 37 and the movable rod 33 are distributed vertically at intervals, and the stirring blades 37 are located between the vertical rods 36.

[0040] The ointment inside the tank 1 is stirred by the stirring blades 37. At the same time, the movable rod 33, vertical rod 36, horizontal rod 34 and scraper 35 will rotate inside the tank 1, also stirring the ointment inside the tank 1, thus increasing the stirring area inside the tank 1.

[0041] like Figures 1-8 As shown, the stirring shaft 31 is connected to the output shaft of the drive motor 22 via a flange. The bottom of the cylindrical shell 21 is open, and its top is closed. The bottom of the cylindrical shell 21 is connected to the top opening of the tank 1 via a flange, which facilitates subsequent maintenance and disassembly.

[0042] like Figures 1-8 As shown, the diameter of the horn-shaped cover 23 gradually decreases from top to bottom, that is, the larger opening of the horn-shaped cover 23 is at the top and the smaller opening is at the bottom, which makes it convenient for the smaller opening at the bottom of the horn-shaped cover 23 to extend into the opening at the top of the tank body 1 and is located above the scraper 35. The scraper 35 does not interfere with the movement of the horn-shaped cover 23. The bottom of the tank body 1 is connected to the discharge port 4, the upper side of the side wall of the tank body 1 is connected to the feed port 5, and the bottom of the tank body 1 is fixedly connected to the support leg 6.

[0043] In practical use, the ointment mixture is first injected into the tank 1 through the inlet 5. The drive motor 22 drives the stirring shaft 31 and stirring blades to quickly stir the ointment mixture. At this time, the bullseye bearing 326 will roll in the horn-shaped cover 23. While stirring, the electric telescopic rod 24 is activated, which moves the limit plate 231 upward, and then moves the horn-shaped cover 23 upward. At this time, under the pressure of the inner wall of the horn-shaped cover 23, the linear bearing 325, the vertical rod 36 and the push rod 322 move towards the stirring shaft 31. The slider 324 squeezes the spring 323. At this time, under the linkage of the movable rod 33, the vertical rod 36 is also moved upward, which in turn moves the scraper 35 closer to the stirring shaft 31 and upward, so that the scraper 35 is away from the inner wall of the tank 1. When the electric telescopic rod 24 moves the limit plate 231 downward, the vertical rod 36 moves upward, and then moves the scraper 35 closer to the stirring shaft 31 and upward, so that the scraper 35 is away from the inner wall of the tank 1. During the movement, under the rebound action of spring 323, the linear bearing 325, vertical rod 36, and push rod 322 are driven away from the stirring shaft 31. At this time, under the linkage of movable rod 33, the vertical rod 36 is also driven to move downward, thereby driving scraper 35 away from stirring shaft 31 and closer to and downward, so that scraper 35 is in contact with the inner wall of tank 1. Thus, the contact time between scraper 35 and inner wall of tank 1 can be controlled during the stirring process. When discharging after stirring, scraper 35 can be in contact with inner wall of tank 1, and the rotation of scraper 35 can scrape off the ointment adhering to inner wall of tank 1, reducing ointment waste. During the stirring process, it is not necessary to scrape inner wall of tank 1 continuously. At this time, scraper 35 can be removed from inner wall of tank 1, reducing power consumption and increasing service life of scraper 35.
