Description

Technical Field

[0001] This invention relates to the field of pharmaceutical raw material processing technology, specifically a raw material pulverizing device with adjustable function. Background Technology

[0002] In the pharmaceutical field, the processing of medicinal materials is one of the key steps in preparing high-quality drugs. The degree of pulverization of raw medicinal materials directly affects subsequent extraction, formulation and other processes, as well as the efficacy and quality stability of drugs. Precisely controlling the particle size of raw medicinal materials is crucial to ensuring the consistency, efficacy and safety of drugs.

[0003] Traditional methods of crushing medicinal materials have many limitations. Traditional medicinal material crushing devices usually use fixed crushing mechanisms, making it difficult to flexibly adjust the crushing particle size according to the characteristics of different medicinal materials and pharmaceutical requirements. This can lead to situations where the crushed particle size is too large or too small when processing different types of medicinal materials, affecting the quality and performance of the medicine. At the same time, in the initial crushing stage of medicinal materials, due to the lack of an effective adjustment mechanism, when the raw materials accumulate at the feed inlet, it is easy to cause blockage of the crushing mechanism. Blockage will not only interrupt the production process and reduce production efficiency, but may also damage the equipment and increase maintenance costs.

[0004] Furthermore, traditional pulverizing devices often cannot detect the size of the crushed particles in real time and dynamically adjust the mode or speed of the pulverizing mechanism based on the detection results. This makes it difficult to ensure that the crushed particle size always meets the requirements during the production process, especially when processing different batches of medicinal materials with different properties, where the problem becomes even more prominent. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material crushing device with an adjustable function to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The aforementioned raw material crushing device with adjustable function includes a machine base, a crushing cylinder, a crushing unit, and an adjusting unit. The machine base is placed on a horizontal foundation, and the crushing cylinder is fixedly installed on the surface of the machine base away from the horizontal foundation. The crushing cylinder is provided with a feed inlet and a discharge outlet. The crushing unit is connected to the fixed machine base, the crushing unit is fixedly connected to the crushing cylinder, and the crushing unit is fixedly connected to the adjusting unit. The crushing unit has the function of improving the feeding efficiency of the adjusting unit and preventing raw material blockage. The adjusting unit is fixedly connected to the crushing cylinder and has the function of adaptively adjusting the particle size.

[0008] The machine is used to install and fix the crushing drum, which in turn is used to install and fix the crushing unit and the adjusting unit. The crushing unit is used for primary crushing of raw materials and to prevent material blockage. The adjusting unit is used to adaptively adjust the particle size of the raw materials. When the raw materials enter the crushing drum from the feed inlet, the crushing unit performs primary crushing of the raw materials and controls the raw materials after primary crushing to prevent blockage, which would affect the feeding and improve crushing efficiency. When the raw materials after primary crushing enter the adjusting unit, the adjusting unit performs secondary crushing and automatically and dynamically adjusts and controls the particle size of the raw materials to ensure that the crushed particle size always meets the requirements.

[0009] Furthermore, the crushing unit includes a motor, a drive wheel, a conveyor belt, a driven wheel, a rotating shaft, a crushing wheel, crushing blades, a dust filter cloth, an elastic ring, a pressure plate, a telescopic spring, a dustproof box, a first electrode plate, and a second electrode plate. The fixed end of the motor is fixedly mounted on the surface of the machine base away from the horizontal foundation. The output end of the motor extends into the crushing cylinder and is fixedly connected to the drive wheel. The drive wheel is connected to the driven wheel via a transmission belt. The driven wheel is fixedly mounted on the rotating shaft near the end of the motor. Both ends of the rotating shaft are rotatably mounted on the inner wall of the crushing cylinder. The crushing wheel is fixedly mounted on the outer surface of the rotating shaft. The crushing wheel has two... The crushing wheel has multiple sets of crushing blades uniformly fixedly installed on its outer surface, with two sets of crushing blades arranged in a cross pattern. The dust filter cloth is fixedly connected to the adjustment unit at one end near the machine base and to an elastic ring at the other end away from the machine base. The elastic ring is slidably installed on the inner wall of the crushing cylinder. The elastic ring is fixedly connected to one end of the pressure plate via a connecting rod, and the other end of the pressure plate is fixedly connected to a telescopic spring. The telescopic spring passes through the dustproof box and is fixedly connected to the first electrode plate. The second electrode plate is fixedly installed on the inner surface of the dustproof box at the end away from the machine base. The second electrode plate is electrically connected to the adjustment unit, and the first electrode plate is electrically connected to the controller.

[0010] When the medicinal materials enter the crushing cylinder through the feed inlet, the controller starts the motor, which drives the drive wheel to rotate. Under the transmission belt, the drive wheel rotates, causing the shaft to rotate the left crushing wheel counter-clockwise. This, in turn, causes the left crushing wheel and its blades to rotate, which in turn drives the right crushing wheel and its blades to rotate clockwise, thus initially crushing the falling medicinal materials. When the left and right sets of crushing blades rotate and contact the pressure plate, the pressure plate is lifted. This pushes the telescopic spring upwards, causing the first and second electrode plates to contact each other and compress the spring. At this time, the positive current in the first electrode plate flows through the second electrode plate to the motor. The telescopic rod, on the other hand, pulls the elastic ring upward along the inner wall of the crushing cylinder under the transmission action of the connecting rod, pulling the filter cloth to tighten, thereby allowing the raw materials of the primary crushed medicinal materials accumulated on the filter cloth to enter the cutting cylinder. When the pressure plate is not in contact with the rotating crushing blades, the pressure plate and the elastic ring move downward under the action of gravity. On the one hand, the first electrode plate and the second electrode plate are disengaged, cutting off the positive current transmission. On the other hand, the elastic ring descends, causing the filter cloth to wrinkle again. Through the tightening and loosening of the filter cloth, the raw materials of the medicinal materials on the filter cloth quickly enter the inside of the cutting cylinder, avoiding the accumulation of raw materials that cause blockage and affect the crushing efficiency, while ensuring that the feed rate inside the cutting cylinder is always stable.

[0011] Furthermore, the adjustment unit includes a second motor, a telescopic shaft, a bar magnet, a cutting disc, a cutting cylinder, a coil, an electromagnet, a round rod, a pinion, a turntable, a smoothing block, a pressure sensor, a memory spring, a thin rod, a crushing ball, an electric telescopic rod, an impact block, and a filter screen. The fixed end of the second motor is fixedly installed inside the discharge port of the crushing cylinder via a straight rod. The output end of the second motor is fixedly connected to the fixed end of the telescopic shaft. The telescopic end of the telescopic shaft is fixedly connected to the bar magnet, which is installed inside the cutting disc. The cutting disc is installed inside the crushing cylinder, and a cutter is provided on its outer surface. The end of the cutting disc near the horizontal foundation is fixedly connected to the telescopic shaft. The end of the cutting cylinder near the horizontal foundation is fixedly installed on the inner surface of the crushing cylinder near the machine platform, and the end away from the horizontal foundation is fixedly connected to the dust filter cloth. The coil is evenly wound on the outer surface of the cutting cylinder, and a cutter is provided on the inner surface of the cutting cylinder. The electromagnet is connected to the outer surface of the telescopic end of the telescopic shaft via a bearing. The electromagnet is fixedly installed on the outer ring of the bearing, and the telescopic shaft is fixedly installed on the inner ring of the bearing. An opening is provided at the end of the electromagnet near the horizontal foundation. The device has a T-shaped groove. One end of the round rod is slidably installed in the electromagnet's T-shaped groove, and the other end is fixedly connected to the turntable. A limit block is provided at one end of the round rod located in the electromagnet's T-shaped groove. The pinion is fixedly installed at the telescopic end of the telescopic shaft. A gear ring is provided inside the turntable, and the pinion meshes with the turntable gear ring. The smoothing block is fixedly installed on the surface of the turntable near the horizontal foundation. The fixed end of the pressure sensor is fixedly installed on the end of the turntable away from the horizontal foundation, and the detection end of the pressure sensor is fixedly installed on the outer surface of the smoothing block. One end of the memory spring is fixedly installed on the inner surface of the smoothing block near the turntable, and the other end is fixedly connected to the thin rod. The memory spring is electrically connected to the coil. The thin rod is slidably installed inside the smoothing block. The crushing ball is rotatably installed on the thin rod. The electric telescopic rod is electrically connected to the second electrode plate. The fixed end of the electric telescopic rod is fixedly connected to the end of the cutting cylinder near the horizontal foundation, and the other end is fixedly connected to the impact block. The filter screen is rotatably installed on the outer surface of the telescopic end of the telescopic shaft. Multiple sets of magnet blocks are fixedly installed on the end of the filter screen near the horizontal foundation.

[0012] When the raw materials, after primary crushing, enter the cutting cylinder, the controller activates the second motor, driving the telescopic shaft to rotate synchronously. This, in turn, causes the cutting disc to rotate within the cylinder, performing secondary crushing on the medicinal materials. As the telescopic shaft rotates, it drives the pinion gear, causing the turntable to rotate slowly on the electromagnet along with the circular rod. Simultaneously, the turntable's rotation drives the smoothing block, creating a differential motion between the smoothing block and the filter screen. When the filter screen rotates rapidly, the material spreads more easily to its surface under centrifugal force. The smoothing block, rotating at a relatively slower speed, smooths the material accumulated on the filter screen, ensuring a more even distribution. This allows the medicinal materials to pass through the filter quickly while preventing clogging. During the smoothing block's rotation, the rapid rotation of the filter screen causes larger particles to be more easily thrown to the filter edge. When the pressure sensor detects excessive pressure exceeding the maximum set value, it indicates that the raw material particle size is too large. At this point, the pressure sensor sends a signal to the controller, which then supplies current to the electromagnet, making the electromagnet and the magnetic block below the filter screen have the same polarity. The repulsive force stretches the telescopic shaft, causing the bar magnet and cutting disc to move upwards, reducing the distance between them and the cutting cylinder. This reduces the particle size of the medicinal materials inside the cutting cylinder. As the bar magnet moves upwards, it changes the magnetic flux, generating current in the coil. When the controller detects that the current in the coil is positive, it sends current to the memory spring for a certain period, causing the memory spring to expand and elongate. This, in turn, drives the grinding ball to grind the large-sized medicinal materials on the filter screen, preventing the screen from clogging. When the pressure sensor detects that the pressure is lower than the minimum set value, it indicates that the particle size is too small and the material passes through the filter screen too quickly. At this time, the controller sends a reverse current to the electromagnet, making the electromagnet have the same polarity as the magnet. Under the attraction, the cutting disc and bar magnet move downwards, increasing the distance between the cutting disc and the cutting cylinder, thus increasing the particle size. When the electric telescopic rod receives a positive current from the second electrode plate, it changes the current direction, pushing the impact block to strike the filter screen, causing the filter screen to vibrate and increasing the filtration speed of medicinal materials that meet the particle size requirements.

[0013] Furthermore, the cutting disc is conical, with the diameter of the end closer to the horizontal foundation being larger than that of the end farther from the horizontal foundation.

[0014] To facilitate the smooth entry of medicinal materials into the cutting cylinder and to allow for adjustments in the distance between the cutting disc and the cylinder during the lifting and lowering process, thereby controlling the crushed particle size of the medicinal materials and improving production efficiency and quality.

[0015] Furthermore, the cutting blades on the outer surface of the cutting disc rotate in opposite directions to the cutting blades on the inner surface of the cutting cylinder.

[0016] When the cutting blades on the cutting disc and the cutting cylinder rotate in opposite directions, the raw medicinal materials are subjected to bidirectional shearing forces between them. This bidirectional shearing action causes the medicinal materials to be cut simultaneously in different directions, greatly improving the crushing efficiency.

[0017] Furthermore, the ratio of the number of teeth on the inner gear ring of the turntable to the number of teeth on the pinion is 10:1.

[0018] To enable differential motion between the smoothing block and the filter screen, thereby enhancing material dispersion and ensuring a more uniform distribution of material on the filter screen, differential rotation allows particles to pass through the filter screen more quickly, reducing filtration time. At the same time, the high-speed rotation of the filter screen generates a large centrifugal force, causing larger particles to be quickly thrown towards the edge of the filter screen, reducing the accumulation of large particles in the central area of ​​the filter screen and thus lowering the risk of filter screen clogging.

[0019] Furthermore, the memory spring extends to its maximum distance, which is consistent with the length of the crushing ball from the filter screen surface.

[0020] To facilitate the grinding of large particles of medicinal materials on the filter screen surface and prevent filter screen clogging, and at the same time, when the memory spring does not receive current, the smoothing block evenly spreads the raw materials on the filter screen surface to improve filtration efficiency.

[0021] Furthermore, the electromagnet is electrically connected to the controller, and the pressure sensor is electrically connected to the controller.

[0022] To facilitate automated control and timely automatic response of the equipment, the lifting and lowering of the cutting disc controls the particle size while grinding excessively large particles on the filter screen, thus preventing filter screen blockage and affecting production efficiency.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, when the crushing blades in the crushing unit rotate and come into contact with the pressure plate, the telescopic spring is pushed upward, causing the first electrode plate and the second electrode plate to come into contact with each other and compress the telescopic spring, thus activating the electric telescopic rod. On the other hand, during the intermittent contact between the pressure plate and the crushing blades, the tightening and loosening of the dust filter cloth allows the medicinal materials on the dust filter cloth to quickly enter the inside of the cutting cylinder, avoiding the accumulation of raw materials that may cause blockage and affect the crushing efficiency, while ensuring that the feeding rate inside the cutting cylinder remains stable at all times.

[0025] 2. This invention uses a differential motion between the smoothing block and the filter screen in the adjustment unit. When the filter screen rotates rapidly, the material diffuses more easily onto the filter screen surface under centrifugal force, making the material more evenly distributed on the filter screen. When the pressure sensor detects that the pressure is too high and exceeds the maximum set value, the electromagnet receives current with the same polarity as the magnet block below the filter screen, pushing the bar magnet and the cutting disc upward, reducing the distance between them and the cutting cylinder, thereby reducing the crushed particle size of the medicinal materials in the cutting cylinder. At the same time, during the upward movement of the bar magnet, the magnetic flux is changed, thereby generating current in the coil. When the controller detects that the direction of the current in the coil is positive, the memory spring delivers current for a certain period of time, expanding and elongating to make the grinding ball grind the medicinal materials with large particle size on the filter screen, avoiding filter screen blockage. When the electric telescopic rod receives positive current from the second electrode plate, it changes the direction of the current, thereby pushing the impact block to impact the filter screen, causing the filter screen to vibrate, thereby increasing the filtration speed of medicinal materials that meet the particle size requirements.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example: Figures 1-13 As shown, the present invention provides a technical solution:

[0042] like Figure 1 , 2As shown, a raw material crushing device with an adjustable function includes a machine base 1, a crushing cylinder 2, a crushing unit 3, and an adjusting unit 4. The machine base 1 is placed on a horizontal foundation, and the crushing cylinder 2 is fixedly installed on the surface of the machine base 1 away from the horizontal foundation. The crushing cylinder 2 is provided with a feed inlet and a discharge outlet. The crushing unit 3 is connected to the fixed machine base 1, the crushing unit 3 is fixedly connected to the crushing cylinder 2, and the crushing unit 3 is fixedly connected to the adjusting unit 4. The crushing unit 3 has the function of improving the feeding efficiency of the adjusting unit 4 and preventing raw material blockage. The adjusting unit 4 is fixedly connected to the crushing cylinder 2 and has the function of adaptively adjusting the particle size.

[0043] Machine base 1 is used to install and fix crushing cylinder 2. Crushing cylinder 2 is used to install and fix crushing unit 3 and adjustment unit 4. Crushing unit 3 is used for primary crushing of raw materials and preventing material blockage. Adjustment unit 4 is used to adaptively adjust the size of raw material particle size. When raw material enters crushing cylinder 2 from the feed port, crushing unit 3 performs primary crushing of raw material and controls the raw material after primary crushing to prevent blockage, affecting feeding and improving crushing efficiency. When the raw material after primary crushing enters adjustment unit 4, adjustment unit 4 performs secondary crushing and automatically and dynamically adjusts and controls the particle size of raw material to ensure that the crushed particle size always meets the requirements.

[0044] like Figure 3 , 4 As shown in Figures 5, 6, 7, and 8, the crushing unit 3 includes a motor 31, a drive wheel 32, a conveyor belt 33, a driven wheel 34, a rotating shaft 35, a crushing wheel 36, crushing blades 37, a dust filter cloth 38, an elastic ring 39, a pressure plate 310, a telescopic spring 311, a dustproof box 312, a first electrode plate 313, and a second electrode plate 314. The fixed end of the motor 31 is fixedly installed on the surface of the machine base 1 away from the horizontal foundation. The output end of the motor 31 extends into the crushing cylinder 2 and is fixedly connected to the drive wheel 32. The drive wheel 32 is connected to the driven wheel 34 through the transmission belt 33. The driven wheel 34 is fixedly installed on the end of the rotating shaft 35 near the motor 31. Both ends of the rotating shaft 35 are rotatably installed on the inner wall of the crushing cylinder 2. The crushing wheel 36 is fixedly installed on the rotating shaft 35. On the outer surface, there are two crushing wheels 36. Multiple sets of crushing blades 37 are evenly fixedly installed on the outer surface of the crushing wheels 36. The two sets of crushing blades 37 are arranged in a cross pattern. The dust filter cloth 38 is fixedly connected to the adjustment unit 4 at one end near the machine base 1 and fixedly connected to the elastic ring 39 at the other end away from the machine base 1. The elastic ring 39 is slidably installed on the inner wall of the crushing cylinder 2. The elastic ring 39 is fixedly connected to one end of the pressure plate 310 through a connecting rod. The other end of the pressure plate 310 is fixedly connected to the telescopic spring 311. The telescopic spring 311 passes through the dustproof box 312 and is fixedly connected to the first electrode plate 313. The second electrode plate 314 is fixedly installed on the inner surface of the dustproof box 312 at the end away from the machine base 1. The second electrode plate 314 is electrically connected to the adjustment unit 4, and the first electrode plate 313 is electrically connected to the controller.

[0045] When the raw medicinal materials enter the crushing cylinder 2 through the feed inlet, the controller starts the motor 31, which drives the drive wheel 32 to rotate. Under the transmission of the transmission belt 33, the driven wheel 34 rotates, causing the shaft 35 to drive the left crushing wheel 36 to rotate counterclockwise. As the left crushing wheel 36 drives the crushing blade 37 to rotate, the right crushing wheel 36 and crushing blade 37 rotate clockwise, thus initially crushing the falling raw medicinal materials. When the crushing blades 37 of the left and right sets rotate and come into contact with the pressure plate 310, the pressure plate 310 is lifted upward. This pushes the telescopic spring 311 upward, causing the first electrode plate 313 and the second electrode plate 314 to come into contact with each other and compress the telescopic spring 311. At this time, the positive current in the first electrode plate 313 passes through the second electrode plate 314. The material flows to the electric telescopic rod 416. On the other hand, under the transmission action of the connecting rod, the elastic ring 39 is pulled to move upward along the inner wall of the crushing cylinder 2, which pulls the dust filter cloth 38 to tighten. This allows the raw materials of the primary crushed medicinal materials accumulated on the dust filter cloth 38 to enter the cutting cylinder 45. When the pressure plate 310 is not in contact with the rotating crushing blade 37, the pressure plate 310 and the elastic ring 39 move downward under the action of gravity. On the one hand, the first electrode plate 313 and the second electrode plate 314 are disengaged, and the positive current transmission is interrupted. On the other hand, the elastic ring 39 descends, causing the dust filter cloth 38 to fold again. Through the tightening and loosening of the dust filter cloth 38, the raw materials of the medicinal materials on the dust filter cloth 38 quickly enter the cutting cylinder 45, avoiding the accumulation of raw materials and blockage, which affects the crushing efficiency, while ensuring that the feeding rate inside the cutting cylinder 45 is always stable.

[0046] like Figure 4 , 9As shown in Figures 10, 11, 12, and 13, the adjustment unit 4 includes a second motor 41, a telescopic shaft 42, a bar magnet 43, a cutting disc 44, a cutting cylinder 45, a coil 46, an electromagnet 47, a round rod 48, a pinion 49, a turntable 410, a smoothing block 411, a pressure sensor 412, a memory spring 413, a thin rod 414, a crushing ball 415, an electric telescopic rod 416, an impact block 417, and a filter screen 418. The fixed end of the second motor 41 is fixedly installed inside the discharge port of the crushing cylinder 2 via a straight rod. The output end of the second motor 41 is fixedly connected to the fixed end of the telescopic shaft 42, and the telescopic end of the telescopic shaft 42 is fixedly connected to the bar magnet 43. A bar magnet 43 is installed inside a cutting disc 44, which is installed inside a crushing cylinder 2. A cutter is provided on the outer surface of the cutting disc 44. The end of the cutting disc 44 closest to the horizontal foundation is fixedly connected to a telescopic shaft 42. A cutting cylinder 45 is fixedly installed on the inner surface of the crushing cylinder 2 closest to the machine base 1, with its end away from the horizontal foundation fixedly connected to a dust filter cloth 38. A coil 46 is evenly wound around the outer surface of the cutting cylinder 45, and a cutter is provided on the inner surface of the cutting cylinder 45. An electromagnet 47 is connected to the outer surface of the telescopic end of the telescopic shaft 42 via a bearing. The electromagnet 47 is fixedly installed on the outer ring of the bearing, and the telescopic shaft 42 is fixedly installed on the inner ring of the bearing. The electromagnet 47 is fixedly installed near the horizontal foundation. A T-shaped groove is provided at one end of the foundation. One end of the round rod 48 is slidably installed in the T-shaped groove of the electromagnet 47, and the other end is fixedly connected to the turntable 410. A limit block is provided at one end of the round rod 48 located in the T-shaped groove of the electromagnet 47. A pinion 49 is fixedly installed at the telescopic end of the telescopic shaft 42. A gear ring is provided inside the turntable 410, and the pinion 49 meshes with the gear ring of the turntable 410. A smoothing block 411 is fixedly installed on the surface of the turntable 410 near the horizontal foundation. The fixed end of the pressure sensor 412 is fixedly installed on the end of the turntable 410 away from the horizontal foundation, and the detection end of the pressure sensor 412 is fixedly installed on the outer surface of the smoothing block 411. Memory spring One end of the spring 413 is fixedly installed on the inner surface of the smoothing block 411 near the turntable 410, and the other end is fixedly connected to the thin rod 414. The memory spring 413 is electrically connected to the coil 46. The thin rod 414 is slidably installed inside the smoothing block 411. The crushing ball 415 is rotatably installed on the thin rod 414. The electric telescopic rod 416 is electrically connected to the second electrode plate 314. The fixed end of the electric telescopic rod 416 is fixedly connected to the end of the cutting cylinder 45 near the horizontal foundation, and the other end is fixedly connected to the impact block 417. The filter screen 418 is rotatably installed on the outer surface of the telescopic end of the telescopic shaft 42. Multiple sets of magnet blocks are fixedly installed on the end of the filter screen 418 near the horizontal foundation.

[0047] When the raw materials, after primary crushing, enter the cutting cylinder 45, the controller starts the motor 41, which drives the telescopic shaft 42 to rotate synchronously. This causes the cutting disc 44 to rotate inside the cutting cylinder 45, performing secondary crushing on the medicinal materials inside the cutting cylinder 45. When the telescopic shaft 42 rotates, it drives the pinion 49 to rotate, which in turn drives the turntable 410 to rotate slowly on the electromagnet 47 along with the round rod 48. At the same time, the rotation of the turntable 410 drives the smoothing block 411 to rotate, creating a differential motion between the smoothing block 411 and the filter screen 418. When the filter screen 418 rotates rapidly, the material is more easily diffused to the surface of the filter screen 418 under the action of centrifugal force, while the smoothing block 411 moves at a relatively slower speed. The slow rotation speed smooths out the material accumulated on the surface of the filter screen 418, making the material more evenly distributed on the filter screen 418. This allows the medicinal raw materials to pass through the filter screen 418 quickly while preventing clogging. As the smoothing block 411 rotates, the rapid rotation of the filter screen 418 makes it easier for larger particles to be thrown to the edge of the filter screen 418. When the pressure sensor 412 detects that the pressure is too high, exceeding the maximum set value, it indicates that the particle size of the crushed raw material is too large. At this time, the pressure sensor 412 sends a signal to the controller, and the controller sends current to the electromagnet 47, causing the electromagnet 47 to be perpendicular to the magnetic block below the filter screen 418. With the same polarity, the telescopic shaft 42 is stretched under the action of repulsive force, thereby driving the bar magnet 43 and the cutting disc 44 to move upward, reducing the distance between them and the cutting cylinder 45, thus reducing the crushed particle size of the medicinal materials in the cutting cylinder 45. During the upward movement of the bar magnet 43, the magnetic flux is changed, thereby generating a current in the coil 46. When the controller detects that the direction of the current in the coil 46 is positive, it sends a current to the memory spring 413 for a certain period of time, causing the memory spring 413 to expand and extend. Under the action of the thin rod 414, it drives the grinding ball 415 to grind the large-particle medicinal materials on the filter screen 418, preventing the filter screen 418 from clogging. When the pressure sensor 412 detects that the pressure is lower than the minimum set value, it indicates that the crushed particle size is too small and the raw material passes through the filter screen 418 too fast. At this time, the controller sends a reverse current to the electromagnet 47, so that the electromagnet 47 presents the same polarity as the magnet block. Under the action of attraction, it drives the cutting disc 44 and the bar magnet 43 to move downward, increasing the distance between the cutting disc 44 and the cutting cylinder 45, and increasing the crushed particle size. When the electric telescopic rod 416 receives the positive current from the second electrode plate 314, it changes the direction of the current, thereby pushing the impact block 417 to impact the filter screen 418, causing the filter screen 418 to vibrate, thereby increasing the filtration speed of the medicinal raw materials that meet the particle size requirements.

[0048] like Figure 4 , 9 As shown in Figure 11, the cutting disc 44 is conical, with the diameter of the end closer to the horizontal foundation being larger than that of the end farther from the horizontal foundation.

[0049] In order to facilitate the smooth entry of medicinal raw materials into the cutting cylinder 45, and to facilitate the adjustment of the distance between the cutting disc 44 and the cutting cylinder 45 during the lifting and lowering process, thereby controlling the crushed particle size of the medicinal raw materials, it is convenient to control the particle size of the medicinal raw materials and improve production efficiency and production quality.

[0050] like Figure 10 As shown, the cutting blades on the outer surface of the cutting disc 44 rotate in opposite directions to the cutting blades on the inner surface of the cutting cylinder 45.

[0051] When the cutting blades on the cutting disc 44 and the cutting cylinder 45 rotate in opposite directions, the medicinal material will be subjected to bidirectional shearing force between them. This bidirectional shearing action allows the medicinal material to be cut in different directions at the same time, which greatly improves the crushing efficiency.

[0052] like Figure 4 As shown, the ratio of the number of teeth on the internal gear ring of turntable 410 to the number of teeth on pinion 49 is 10:1.

[0053] To enable the smoothing block 411 and the filter screen 418 to move at different speeds, thereby enhancing material dispersion and making the material more evenly distributed on the filter screen 418, the differential rotation allows particles to pass through the filter screen 418 more quickly, reducing filtration time. At the same time, the high-speed rotation of the filter screen 418 can generate a large centrifugal force, causing larger particles to be quickly thrown to the edge of the filter screen 418, reducing the accumulation of large particles in the central area of ​​the filter screen 418, thus reducing the risk of filter screen 418 clogging.

[0054] like Figure 4 As shown, the memory spring 413 extends to its limit distance, which is consistent with the distance between the crushing ball 415 and the surface of the filter screen 418.

[0055] In order to facilitate the grinding of large-particle medicinal materials on the surface of filter screen 418 and avoid clogging of filter screen 418, and at the same time, when memory spring 413 does not receive current, smoothing block 411 evenly spreads the raw materials on the surface of filter screen 418 to improve filtration efficiency.

[0056] like Figure 11 , 12 As shown, electromagnet 47 is electrically connected to the controller, and pressure sensor 412 is electrically connected to the controller.

[0057] To facilitate automated control and timely automatic response of the device, the lifting and lowering of the cutting disc 44 controls the particle size while grinding excessively large particles on the filter screen 418, thus preventing the filter screen 418 from becoming clogged and affecting production efficiency.

[0058] Working principle of the invention:

[0059] When the raw medicinal materials enter the crushing cylinder 2 through the feed inlet, the controller starts the motor 31, which drives the drive wheel 32 to rotate. Under the transmission of the transmission belt 33, the driven wheel 34 rotates, causing the shaft 35 to drive the left crushing wheel 36 to rotate counterclockwise. As the left crushing wheel 36 drives the crushing blade 37 to rotate, the right crushing wheel 36 and crushing blade 37 rotate clockwise, thus initially crushing the falling raw medicinal materials. When the crushing blades 37 of the left and right sets rotate and come into contact with the pressure plate 310, the pressure plate 310 is lifted upward. This pushes the telescopic spring 311 upward, causing the first electrode plate 313 and the second electrode plate 314 to come into contact with each other and compress the telescopic spring 311. At this time, the positive current in the first electrode plate 313 flows through the second electrode plate 314 to the electric telescopic rod 416. When the electric telescopic rod 416 receives the positive current from the second electrode plate 314, it changes the electrical current. The flow direction pushes the impact block 417 to impact the filter screen 418, causing the filter screen 418 to vibrate, thereby increasing the filtration speed of the medicinal materials that meet the particle size requirements. On the other hand, under the transmission action of the connecting rod, the elastic ring 39 is pulled to move upward along the inner wall of the crushing cylinder 2, pulling the dust filter cloth 38 to tighten, thereby allowing the medicinal materials that have completed primary crushing accumulated on the dust filter cloth 38 to enter the cutting cylinder 45. When the pressure plate 310 is not in contact with the rotating crushing blade 37, the pressure plate 310 and the elastic ring 39 move downward under the action of gravity. On the one hand, the first electrode plate 313 and the second electrode plate 314 are disengaged, disconnecting the positive current transmission. On the other hand, the elastic ring 39 descends, causing the dust filter cloth 38 to fold again. Through the tightening and loosening of the dust filter cloth 38, the medicinal materials on the dust filter cloth 38 quickly enter the interior of the cutting cylinder 45, avoiding the accumulation of raw materials that cause blockage and affect the crushing efficiency, while ensuring that the cutting cylinder 45 always maintains a stable feeding rate.

[0060] When the raw materials, after primary crushing, enter the cutting cylinder 45, the controller starts the motor 41, which drives the telescopic shaft 42 to rotate synchronously. This, in turn, drives the cutting disc 44 to rotate within the cutting cylinder 45, performing secondary crushing on the medicinal materials. When the telescopic shaft 42 rotates, it drives the pinion 49 to rotate, which in turn drives the turntable 410 to rotate slowly on the electromagnet 47 along with the round rod 48. Simultaneously, the rotation of the turntable 410 drives the smoothing block 411 to rotate, creating a differential motion between the smoothing block 411 and the filter screen 418. When the filter screen 418 rotates rapidly, the material is more easily dispersed under centrifugal force. The material on the surface of the filter screen 418 diffuses, while the smoothing block 411 rotates at a relatively slow speed, smoothing the material accumulated on the surface of the filter screen 418, making the material more evenly distributed on the filter screen 418. This allows the medicinal raw materials to pass through the filter screen 418 quickly while preventing the filter screen 418 from clogging. During the rotation of the smoothing block 411, the rapid rotation of the filter screen 418 makes it easier for larger particles to be thrown towards the edge of the filter screen 418. When the pressure sensor 412 detects that the pressure is too high, exceeding the maximum set value, it indicates that the particle size of the crushed raw material is too large. At this time, the pressure sensor 412... The controller sends a feedback signal and supplies current to the electromagnet 47, making the electromagnet 47 and the magnet below the filter screen 418 have the same polarity. This causes the repulsive force to stretch the telescopic shaft 42, thereby moving the bar magnet 43 and the cutting disc 44 upwards, reducing the distance between them and the cutting cylinder 45, thus lowering the particle size of the raw medicinal materials inside the cutting cylinder 45. During the upward movement of the bar magnet 43, the magnetic flux changes, generating current in the coil 46. When the controller detects that the current in the coil 46 is positive, it supplies current to the memory spring 413 for a certain period of time, thereby... The memory spring 413 expands and elongates, thereby driving the crushing ball 415 to grind the large-sized medicinal materials on the filter screen 418 under the action of the thin rod 414, thus preventing the filter screen 418 from clogging. When the pressure sensor 412 detects that the pressure is lower than the minimum set value, it proves that the crushed particle size is too small and the material passes through the filter screen 418 too fast. At this time, the controller sends a reverse current to the electromagnet 47, so that the electromagnet 47 presents the same polarity as the magnet block. Under the action of attraction, it drives the cutting disc 44 and the bar magnet 43 to move downward, increasing the distance between the cutting disc 44 and the cutting cylinder 45, and increasing the crushed particle size.
