[0002] In the modernization of traditional Chinese medicine and the extraction and preparation of natural drugs, the crushing of raw materials is a key process that determines the extraction efficiency of medicinal components. The dissolution rate of effective components of traditional Chinese medicine, such as alkaloids, flavonoids, and volatile oils, is closely related to the degree of crushing of raw materials. Different medicinal materials and extraction processes have significantly different requirements for the crushing state of materials.
[0003] Chinese utility model patent CN219073049U discloses an environmentally friendly pharmaceutical material pulverizing device, including a raw material bin, a pulverizing bin, and a dust collection cabinet. Two sets of first pulverizing wheels are rotatably mounted on the upper part of the pulverizing bin, and two sets of first motors are fixedly mounted on the upper front of the pulverizing bin. Two sets of second pulverizing wheels are rotatably mounted below the first pulverizing wheels, and a second motor is fixedly mounted below the first motors. A collection bin is located at the lower part of the pulverizing bin. A feeding pipe is fixedly connected to the inside of the raw material bin, and a feeding motor is fixedly mounted on the top of the feeding pipe. A feeding winch is fixedly connected to the output end of the feeding motor. This utility model, through the combination of various structures, enables the device to automatically feed pharmaceutical raw materials during use, reducing the workload of operators. Simultaneously, it can remove dust generated during pulverizing operations, increasing functionality and expanding the scope of application.
[0004] In the current pharmaceutical manufacturing process, due to the significant differences in the required particle size of raw materials for different products, existing devices lack the function of graded discharge, making it difficult to produce products of different particle sizes in the same equipment.

A discharging frame 302 is fixedly connected to the outer surface of the slider 310. An inclined surface is provided on the inner side of the discharging frame 302. A collection bin 305 is slidably connected to the bottom of the inner wall of the crushing shell 1. A limit rod 301 is fixedly connected to the upper surface of the discharging frame 302.
[0031] Furthermore, a guide plate 307 is fixedly connected to the inner wall of the crushing shell 1. Two sets of second crushing roller shafts 306 are arranged below the guide plate 307. The two ends of the second crushing roller shafts 306 are rotatably connected to the inner wall of the crushing shell 1. A third reduction motor 311 is fixedly connected to the outer surface of the crushing shell 1. The output shaft of the third reduction motor 311 is fixedly connected to the outer surface of the second crushing roller shafts 306. A fixed frame 308 is arranged below the second crushing roller shafts 306. The fixed frame 308 is fixedly connected to the inner wall of the crushing shell 1. The outer surface of the fixed frame 308 is slidably connected to the upper surface of the discharge frame 302. A first crushing roller shaft 304 is arranged below the support rod 309. The outer surface of the first crushing roller shaft 304 is rotatably connected to the inner wall of the crushing shell 1. A second reduction motor 303 is fixedly connected to the outer surface of the crushing shell 1. The output shaft of the second reduction motor 303 is fixedly connected to the outer surface of the first crushing roller shaft 304.
[0032] In this embodiment, by controlling the sliding of the discharge frame 302, different crushing requirements can be achieved. The discharge frame 302 is pushed to discharge the initially crushed material. If fine crushing is required, the slider 310 is sealed to the inner wall of the crushing shell 1, the second reduction motor 303 is started, and the first crushing roller 304 performs secondary crushing of the initially crushed material to meet different fineness requirements and flexibly adapt to production needs.
[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the feeding mechanism 2 includes a feeding bin 203 and a screw feeder 202 fixedly connected to the outer surface of the crushing shell 1. A fixing plate 207 is fixedly connected to the inner wall of the feeding bin 203. A feeding groove 204 is opened on the outer surface of the fixing plate 207. The feed inlet of the screw feeder 202 extends into the interior of the feeding groove 204. A rotating shaft 205 is rotatably connected to the inner wall of the feeding bin 203.
[0034] Furthermore, multiple sets of rubber blocks 206 are fixedly connected to the outer surface of the rotating shaft 205. The outer surface of the rubber blocks 206 is in contact with the lower surface of the fixed plate 207. The outer surface of the fixed plate 207 is oriented with the tilting box feeding groove 204. A first reduction motor 201 is fixedly connected to the outer surface of the feeding bin 203. The output shaft of the first reduction motor 201 is fixedly connected to the outer surface of the rotating shaft 205. A control panel 4 is fixedly connected to the outer surface of the crushing shell 1. It should be noted that the screw conveyor 202 adopts the Archimedes screw conveying principle in the prior art. Its structure includes components such as a screw conveying shaft, a conveying cylinder, a drive motor, and a reduction gearbox. The screw blades are welded to the shaft and placed in the sealed cylinder. The material is conveyed axially by rotating the motor. This technology has been widely used in the pharmaceutical industry.
[0035] In this embodiment, after the first reduction motor 201 is started, the rotating shaft 205 drives the rubber block 206 to rotate and hit the fixed plate 207, causing it to vibrate slightly. With the inclined fixed plate 207, the material can be smoothly guided to the feeding groove 204. At the same time, the screw feeder 202 continuously feeds the material into the crushing shell 1. The combination of vibration guiding and screw conveying ensures that the feeding process is efficient and stable, and avoids material accumulation and blockage.
[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0037] Working principle: First, the material is placed on the upper surface of the fixed plate 207. Then, the screw conveyor 202 and the first reduction motor 201 are started. The output shaft of the first reduction motor 201 drives the rotating shaft 205 and the rubber block 206 to rotate. The rotating rubber block 206 impacts the lower surface of the fixed plate 207, causing slight vibrations on the outer surface of the fixed plate 207, which facilitates guiding the raw material into the feeding groove 204. At the same time, the screw conveyor 202 is started, and it guides the material in the feeding bin 203 into the crushing shell 1. Then, the third reduction motor 311 is started. The output shaft of the third reduction motor 311 drives the second crushing roller shaft 306 to rotate. The rotation of the second crushing roller shaft 306 facilitates the preliminary crushing of the Chinese medicinal materials. The preliminarily crushed material falls into the... The upper surface of the fixed frame 308 pushes the discharge frame 302, causing the discharge frame 302 to drive the fixed frame 308 to slide on the outer surface of the support rod 309, so that the outer surface of the limit rod 301 and the outer surface of the crushing shell 1 are in contact, thus facilitating the discharge of the material after preliminary crushing. When fine crushing is required, the outer surface of the slider 310 is in contact with the inner wall of the crushing shell 1 to facilitate sealing of the crushing shell 1. Then, the second reduction motor 303 is started, so that the raw material after preliminary crushing falls on the outer surface of the first crushing roller shaft 304. The output shaft of the second reduction motor 303 drives the first crushing roller shaft 304 to rotate, which facilitates secondary crushing of the material, so that the crushed material falls into the collection bin 305.
