Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine technology, specifically a low-temperature ultrafine pulverizer for traditional Chinese medicine raw materials. Background Technology

[0002] Traditional Chinese medicine (TCM) treatment is a unique treatment method in my country. In the process of using certain TCMs, in order to facilitate patients' use, doctors often need to use an ultra-micro pulverizer to pulverize the raw materials of TCMs in a low-temperature environment. Ultra-micro pulverization refers to the combination of advanced ultra-micro pulverization technology and traditional TCM theory to pulverize TCM materials, TCM extracts, TCM preparations, and TCM formulas into micro-powders.

[0003] A search revealed Chinese Patent CN218486097U, which discloses a low-temperature ultrafine pulverizer for traditional Chinese medicinal materials, relating to the field of ultrafine pulverizer technology. Through the coordinated arrangement of the pulverizer housing, pre-pulverizing mechanism, motor one, and sprocket two, it facilitates the pre-pulverization of raw materials, effectively avoiding the reduced ultrafine pulverization effect caused by the relatively intact structure of the raw materials during ultrafine pulverization, and also preventing severe wear and tear on the ultrafine pulverizing components within the pulverizer.

[0004] While the above solutions make it easier to pre-crush raw materials of traditional Chinese medicine, effectively avoiding the reduced ultra-fine crushing effect caused by the relatively intact structure of the raw materials, the ultra-fine crushers in the aforementioned patents have difficulty adjusting the sieve hole diameter of the filter plate. Different medicinal materials have different requirements for particle size, and fixed sieve holes cannot meet diverse needs, resulting in some medicinal materials being over-crushed or under-crushed. Therefore, we provide a low-temperature ultra-fine crusher for raw materials of traditional Chinese medicine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a low-temperature ultrafine pulverizer for Chinese medicinal materials to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature ultrafine pulverizer for Chinese medicinal materials, comprising an outer casing and a filter plate disposed inside the outer casing. The lower surface of the filter plate is provided with an aperture adjustment mechanism. The aperture adjustment mechanism includes a fixing ring fixedly connected to the lower surface of the filter plate. A third sliding groove is provided on the outer side of the fixing ring. A slider is slidably connected inside the third sliding groove. An adjustment plate is fixedly connected to the upper end of the slider. A sliding column is fixedly connected to the upper surface of the adjustment plate.

[0007] An electric telescopic rod is hinged to the lower surface of the filter plate, and a rotating sleeve is hinged to the telescopic end of the electric telescopic rod. A first sliding groove is provided on the inner wall of the rotating sleeve, and the interior of the first sliding groove is slidably connected to the sliding column.

[0008] Preferably, the outer side of the fixing ring is provided with a second sliding groove, and the inner side of the second sliding groove is rotatably connected to the inner side of the rotating sleeve. When the rotating sleeve is rotated and adjusted, the second sliding groove provided on the fixing ring can restrict the rotating sleeve and prevent it from falling off during rotation.

[0009] Preferably, the inner wall of the outer casing is slidably connected to one side of the filter plate, a first handle is fixedly connected to one side of the filter plate, the inner wall of the filter plate is provided with filter holes, the filter plate is installed inside the outer casing, and the pulverized Chinese medicinal materials can be filtered through the filter plate.

[0010] Preferably, a protective shell is fixedly connected to one side of the outer casing, a motor is fixedly connected to the inner side of the protective shell, and a first crushing roller is fixedly connected to the output shaft of the motor. The protective shell can protect the transmission equipment and prevent injury to workers during operation.

[0011] Preferably, a first sprocket is fixedly connected to the outer surface of the output shaft of the motor, a chain is engaged on the outer surface of the first sprocket, a second sprocket is engaged on the inner side of the chain, and a second pulverizing roller is fixedly connected to the middle of the second sprocket. Under the action of the motor, the first sprocket, the chain and the pulverizing rollers on both sides can be driven to rotate, which can perform ultra-fine pulverization of Chinese medicinal materials.

[0012] Preferably, the first pulverizing tube and the second pulverizing roller both pass through the outer casing and are rotatably connected to the outer casing. An observation window is provided on the front side of the outer casing, and a control device is provided on the left side of the outer casing. The pulverizing device can be controlled to pulverize Chinese medicinal materials through the control settings, and the staff can observe the pulverization of Chinese medicinal materials through the observation window.

[0013] Preferably, the outer casing has a door panel hinged to the front, and a second handle is fixedly connected to one side of the door panel, allowing staff to easily open the door panel and remove the pulverized Chinese medicinal materials.

[0014] Preferably, a limiting plate is rotatably connected to the front side of the outer casing, and the inner side of the limiting plate is engaged with one side of the filter plate. The limiting plate can restrict the filter plate and prevent it from sliding during operation.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The low-temperature ultrafine pulverizer of this application uses a combination of an electric telescopic rod, a rotating sleeve, a first sliding groove, a fixed ring, a second sliding groove, a third sliding groove, a slider, an adjusting plate, and a sliding column. The dynamic adjustment function allows the equipment to flexibly control the fineness of the powder even in low-temperature environments. By reducing the aperture, it can ensure that the medicinal materials are pulverized to ultrafine particles in a single pass under low-temperature embrittlement conditions, reducing the energy loss caused by repeated pulverization at low temperatures. At the same time, it avoids the damage to the effective components of heat-sensitive medicinal materials caused by over-pulverization. This design ensures pulverization efficiency while taking into account the integrity of the active components of the medicinal materials, and realizes the adjustment of the screen aperture.

[0017] 2. The low-temperature ultrafine pulverizer of this application uses a motor, a first sprocket, a first pulverizing roller, a chain, a second sprocket, a second pulverizing roller, and a control device in combination. The control device can precisely adjust the speed of the motor to match the low-temperature pulverization requirements of different medicinal materials. Frozen brittle medicinal materials require low speed and high torque, while heat-sensitive medicinal materials require rapid pulverization to reduce temperature rise. The synchronous operation of the two rollers reduces the material residence time. Combined with the low-temperature environment of the outer casing, it effectively inhibits the loss of heat-sensitive components during the pulverization process and ensures the integrity of the active ingredients of the medicinal materials.

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

[0030] like Figure 2 and Figure 4 As shown, this utility model provides a technical solution for a low-temperature ultrafine pulverizer for Chinese medicinal materials, including an outer casing 1 and a filter plate 2 disposed inside the outer casing 1. A limiting plate 17 is rotatably connected to the front side of the outer casing 1. The inner side of the limiting plate 17 is engaged with one side of the filter plate 2. The limiting plate 17 is installed on the outer casing 1, and the filter plate 2 can be fixed by the limiting plate 17 to prevent the filter plate 2 from becoming loose when filtering Chinese medicinal materials, thus affecting the filtration effect. A door panel 14 is hinged to the front side of the outer casing 1. A second handle 15 is fixedly connected to one side of the door panel 14. The door panel 14 is installed on the outer casing 1. When it is necessary to take out the pulverized Chinese medicinal materials, the operator can pull the second handle 15 to open the door panel 14 for easy removal of the Chinese medicinal materials.

[0031] like Figure 5 As shown, a protective shell 5 is fixedly connected to one side of the outer casing 1, and a motor 6 is fixedly connected to the inner side of the protective shell 5. A first sprocket 7 is fixedly connected to the outer surface of the output shaft of the motor 6. A chain 9 is engaged on the outer surface of the first sprocket 7, and a second sprocket 10 is engaged on the inner side of the chain 9. A second pulverizing roller 11 is fixedly connected to the middle of the second sprocket 10. The motor 6 can drive the first sprocket 7, chain 9, and second sprocket 10 to rotate, thereby driving the first pulverizing roller 8 and the second pulverizing roller 11 to perform ultra-fine pulverization of Chinese medicinal materials. The output shaft of the motor 6 is fixedly connected to the first pulverizing roller 8. The protective shell 5 is installed on the outer casing 1. The protective shell 5 can protect the first sprocket 7, chain 9, and second sprocket 10 to prevent injury to workers during operation, thus playing a protective role.

[0032] like Figure 1 As shown, the first crushing roller 8 and the second crushing roller 11 both pass through the outer box 1 and are rotatably connected to the outer box 1. An observation window 13 is provided on the front side of the outer box 1, and a control device 12 is provided on the left side of the outer box 1. The first crushing roller 8 and the second crushing roller 11 are installed inside the outer box 1. The first crushing roller 8 and the second crushing roller 11 can be fixed through the outer box 1 to prevent them from falling off during crushing. The observation window 13 on the outer box 1 allows the staff to easily observe the crushing process. The inner wall of the outer box 1 is slidably connected to one side of the filter plate 2. A first handle 4 is fixedly connected to one side of the filter plate 2. The inner wall of the filter plate 2 has filter holes 16. The filter plate 2 is installed inside the outer box 1. The crushed Chinese medicinal materials can be filtered through the filter holes 16 on the filter plate 2. When it is necessary to replace the filter plate 2, the first handle 4 can be pulled to easily pull out the filter plate 2 and replace it with a new filter plate 2 to filter the Chinese medicinal materials.

[0033] like Figure 3 As shown, the lower surface of the filter plate 2 is provided with an aperture adjustment mechanism 3. The aperture adjustment mechanism 3 includes a fixing ring 304 fixedly connected to the lower surface of the filter plate 2. A second sliding groove 305 is provided on the outer side of the fixing ring 304. The inner side of the second sliding groove 305 is rotatably connected to the inner side of the rotating sleeve 302. The second sliding groove 305 provided on the fixing ring 304 can cause the rotating sleeve 302 to fall off when rotating, which plays a limiting role.

[0034] like Figure 6 , Figure 7 and Figure 8 As shown, a third sliding groove 306 is provided on the outer side of the fixing ring 304. A slider 307 is slidably connected inside the third sliding groove 306. An adjusting plate 308 is fixedly connected to the upper end of the slider 307.

The third sliding groove 306 provided on the fixing ring 304 allows the slider 307 to slide inside it. The adjusting plate 308 adjusts the aperture under the action of the slider 307.

[0035] An electric telescopic rod 301 is hinged to the lower surface of the filter plate 2. A rotating sleeve 302 is hinged to the telescopic end of the electric telescopic rod 301. A first sliding groove 303 is provided on the inner wall of the rotating sleeve 302. The interior of the first sliding groove 303 is slidably connected to the sliding column 309. Under the action of the electric telescopic rod 301, the rotating sleeve 302 can be pushed to rotate on the fixed ring 304. The first sliding groove 303 on the rotating sleeve 302 can drive the sliding column 309 and the adjusting plate 308 to adjust the aperture, which is beneficial to improving the filtration efficiency.

[0036] The electric telescopic pole 301, motor 6, first sprocket 7, chain 9, second sprocket 10 and control device 12 in this application are all common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.

[0037] Working principle: The equipment pulverizes Chinese medicinal materials in a low-temperature environment, making the raw materials brittle, which facilitates efficient pulverization and protects heat-sensitive components. First, the Chinese medicinal materials are placed into the outer casing 1 through a funnel. Then, the motor 6 is started, which drives the first sprocket 7 and chain 9 to rotate. The chain 9 drives the second sprocket 10 to rotate synchronously, causing the first pulverizing roller 8 and the second pulverizing roller 11 to rotate synchronously in opposite directions. The medicinal materials enter the gap between the two pulverizing rollers and are initially pulverized by shearing and extrusion. Then, they enter the ultra-fine pulverization stage to further refine the particles. The aperture adjustment mechanism 3 is activated to adjust the aperture. The electric telescopic rod 301 extends and retracts, pushing the rotating sleeve 302. Rotating around the fixed ring 304, the first sliding groove 303 on the inner wall of the rotating sleeve 302 drives the sliding column 309 to move, and the slider 307 slides along the third sliding groove 306, driving the adjusting plate 308 to move horizontally. The movement of the adjusting plate 308 covers the filter holes 16 on the filter plate 2, thereby reducing or expanding the effective sieve hole diameter and realizing the dynamic adjustment of powder fineness. After being crushed, the medicinal material particles fall through the sieve holes of the filter plate 2 after adjustment. Particles that do not meet the standards are intercepted and continue to be crushed. The staff monitors the crushing status through the observation window 13 and adjusts the speed of the motor 6 and the size of the sieve holes through the control device 12. Finally, the ultrafine powder is taken out after the second handle 15 at the door plate 14 is opened, realizing the adjustment of the sieve hole diameter.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
