Description

Technical Field

[0001] The invention relates to the technical field of pharmaceutical raw material processing, in particular to a raw material crushing device with an adjusting function. Background Art

[0002] In the pharmaceutical field, the processing of medicinal materials is one of the key links in the preparation of high-quality medicines. The degree of crushing of medicinal raw materials directly affects the subsequent extraction, preparation and other process as well as the efficacy and quality stability of the medicines. Accurately controlling the crushed particle size of medicinal raw materials is crucial to ensure the consistency, effectiveness and safety of the medicines.

[0003] There are many limitations in the traditional method of crushing medicinal materials. Traditional medicinal material crushing devices usually use fixed crushing mechanisms, which make it difficult to flexibly adjust the crushing particle size according to the characteristics of different medicinal materials and pharmaceutical requirements. This leads to the situation that the crushing particle size is too large or too small when processing different types of medicinal materials, affecting the quality and performance of the medicines. At the same time, in the primary crushing stage of medicinal materials, due to the lack of an effective adjustment mechanism, when the medicinal materials are piled up 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] In addition, traditional crushing devices often cannot detect the size of the crushed particles in real time and dynamically adjust the mode or speed of the crushing mechanism according to 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. Summary of the invention

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

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The raw material crushing device with an adjustment function comprises a machine table, a crushing barrel, a crushing unit and an adjustment unit. The machine table is placed on a horizontal basis, the crushing barrel is fixedly installed on the surface of one end of the machine table away from the horizontal basis, the crushing barrel is provided with a feed port and a discharge port, the crushing unit is connected to the fixed machine table, the crushing unit is fixedly connected to the crushing barrel, the crushing unit is fixedly connected to the adjustment unit, the crushing unit has the function of improving the feeding efficiency of the adjustment unit and preventing the blockage of raw materials, the adjustment unit is fixedly connected to the crushing barrel, and the adjustment unit has the function of adaptively adjusting the particle size.

[0008] The machine is used to install a fixed crushing drum, and the crushing drum is used to install a fixed grinding unit and an adjusting unit. The grinding 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 feeding port of the crushing drum, the raw materials are initially crushed by the grinding unit, and at the same time, the raw materials after the primary crushing are controlled not to be blocked, which affects the feeding and improves the crushing efficiency. When the raw materials after the primary crushing enter the adjusting unit, they are crushed again by the adjusting unit, and at the same time, the particle size of the raw materials is automatically and dynamically adjusted to ensure that the crushed particle size always meets the requirements.

[0009] Furthermore, the crushing unit includes a motor, a driving wheel, a conveyor belt, a driven wheel, a rotating shaft, a crushing wheel, crushing leaves, a dust filter cloth, an elastic ring, a pressure plate, a telescopic spring, a dust box, a first electrode plate and a second electrode plate. The fixed end of the motor is fixedly mounted on the surface of the end of the machine away from the horizontal foundation. The output end of the motor extends into the crushing barrel and is fixedly connected to the driving wheel. The driving wheel is connected to the driven wheel through a transmission belt. The driven wheel is fixedly mounted on the end of the rotating shaft close to the motor. The two ends of the rotating shaft are rotatably mounted on the inner wall of the crushing barrel. The crushing wheel is fixedly mounted on the outer surface of the rotating shaft. The crushing wheel has two A plurality of groups of crushing leaves are evenly and fixedly installed on the outer surface of the crushing wheel, and the two groups of crushing leaves are cross-arranged, the dust filter cloth is fixedly connected to the adjusting unit at one end close to the machine, and is fixedly connected to the elastic ring at one end away from the machine, 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 through a connecting rod, the other end of the pressure plate is fixedly connected to the 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 one end away from the machine, the second electrode plate is electrically connected to the adjusting unit, and the first electrode plate is electrically connected to the controller.

[0010] When the medicinal material enters the crushing barrel through the crushing barrel feeding port, the controller controls the motor to start, thereby driving the driving wheel to rotate, and the driven wheel is driven to rotate under the transmission action of the transmission belt, so that the rotating shaft drives the left crushing wheel to rotate counterclockwise, so that the left crushing wheel drives the crushing leaves to rotate, and the right crushing wheel and crushing leaves to rotate clockwise, so as to initially crush the falling medicinal material. When the left and right groups of crushing leaves rotate and contact with the pressure plate, the pressure plate is lifted upward, and on the one hand, the telescopic spring is pushed up to drive the first electrode plate and the second electrode plate to contact each other and compress the telescopic spring. At this time, the positive current in the first electrode plate flows to the electric motor through the second electrode plate. 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, and pulls the dust filter cloth to tighten, so that the primary crushed medicinal materials accumulated on the dust filter cloth enter the cutting cylinder. When the pressing plate is not in contact with the rotating crushing leaves, the pressing plate and the elastic ring move downward under the action of gravity. On the one hand, the first electrode plate is disengaged from the second electrode plate, disconnecting the forward current transmission, and on the other hand, the elastic ring descends to make the dust filter cloth wrinkle again. Through the tightening and relaxation of the dust filter cloth, the medicinal materials on the dust filter cloth quickly enter the interior of the cutting cylinder, avoiding blockage caused by raw material accumulation, affecting the crushing efficiency, while ensuring that the cutting cylinder always maintains a stable feeding rate.

[0011] Furthermore, the adjusting unit includes motor 2, telescopic shaft, bar magnet, cutting disc, cutting cylinder, coil, electromagnet, round rod, pinion, turntable, smoothing block, pressure sensor, memory spring, thin rod, rolling ball, electric telescopic rod, impact block and filter screen, the fixed end of motor 2 is fixedly installed in the discharge port of the crushing cylinder through a straight rod, the output end of motor 2 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, the bar magnet is installed inside the cutting disc, the cutting disc is installed inside the crushing cylinder, a cutting knife is arranged on the outer surface of the cutting disc, the cutting disc is fixedly connected to the telescopic shaft at one end close to the horizontal foundation, the cutting cylinder is fixedly installed on the inner surface of the crushing cylinder close to the machine at one end close to the horizontal foundation, and is fixedly connected to the dust filter cloth at one end away from the horizontal foundation, the coil is evenly wound on the outer surface of the cutting cylinder, the inner surface of the cutting cylinder is provided with a cutting knife, the electromagnet is connected to the outer surface of the telescopic end of the telescopic shaft through a bearing, the electromagnet is fixedly installed on the outer ring of the bearing, the telescopic shaft is fixedly installed on the inner ring of the bearing, and the electromagnet is opened at one end close to the horizontal foundation There is a T-shaped slide groove, one end of the round rod is slidably installed in the T-shaped slide groove of the electromagnet, and the other end is fixedly connected to the turntable, a limit block is arranged at one end of the round rod located in the T-shaped slide groove of the electromagnet, the pinion is fixedly installed on the telescopic end of the telescopic shaft, a gear ring is arranged inside the turntable, the pinion is meshed and connected with the turntable gear ring, the smoothing block is fixedly installed on the surface of one end of the turntable close to the horizontal foundation, the fixed end of the pressure sensor is fixedly installed on the end of the turntable away from the horizontal foundation, 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 close to one end of 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 rolling 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 one end of the cutting cylinder close to the horizontal foundation, and the other end is fixedly connected to the impact block, the filter is rotatably installed on the outer surface of the telescopic end of the telescopic shaft, and a plurality of groups of magnet blocks are fixedly installed on one end of the filter close to the horizontal foundation.

[0012] When the raw materials after primary crushing enter the cutting cylinder, the controller controls the second motor to start and drive the telescopic shaft to rotate synchronously, thereby driving the cutting disc to rotate in the cutting cylinder, and performing secondary crushing on the medicinal materials in the cutting cylinder. When the telescopic shaft rotates and drives the pinion to rotate, the turntable is driven to rotate slowly on the electromagnet along with the round rod. At the same time, the rotation of the turntable drives the smoothing block to rotate, so that the smoothing block and the filter form a differential motion. When the filter rotates quickly, the material is more likely to diffuse to the surface of the filter under the action of centrifugal force, and the smoothing block rotates at a relatively slow speed, which can smooth the material accumulated on the surface of the filter, so that the material is more evenly distributed on the filter, so that the medicinal materials can pass through the filter quickly while avoiding the filter from being blocked. When the smoothing block rotates, the rapid rotation of the filter makes it easier for particles with larger particle sizes to be thrown to the edge of the filter. When the pressure sensor detects that the pressure is too high and exceeds the maximum set value, it proves that the particle size of the crushed raw material is too large. At this time, the pressure sensor feeds back a signal to the controller, and the controller transmits current to the electromagnet, so that the electromagnet and the magnet block under the filter have the same polarity. Thus, the telescopic shaft is stretched under the action of the repulsive force, thereby driving the bar magnet and the cutting disc to move upward, reducing the distance between the bar magnet and the cutting barrel, thereby reducing the crushed particle size of the medicinal material in the cutting barrel. 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, it transmits current to the memory spring for a certain period of time, thereby causing the memory spring to expand and elongate, thereby driving the rolling ball to grind the medicinal material with large particle size on the filter screen under the action of the thin rod to avoid clogging of the filter screen. When the pressure sensor detects that the pressure is lower than the minimum set value, it proves that the crushed particle size is too small and the raw material passes through the filter screen too fast. At this time, the controller transmits a reverse current to the electromagnet, so that the electromagnet presents the same polarity as the magnet block, and drives the cutting disc and the bar magnet to move downward under the action of the attraction, increasing the distance between the cutting disc and the cutting barrel and increasing the crushed particle size. When the electric telescopic rod receives the positive current from the second electrode plate, the current direction is changed to push the impact block to impact the filter screen, causing the filter screen to vibrate, thereby increasing the filtering speed of the medicinal material raw materials that meet the particle size requirements.

[0013] Furthermore, the cutting disc is conical, and the diameter of the end close to the horizontal base is larger than the diameter of the end away from the horizontal base.

[0014] In order to facilitate the smooth entry of medicinal raw materials into the cutting cylinder and to facilitate the change of the distance between the cutting disc and the cutting cylinder during the lifting process, the crushed particle size of the medicinal raw materials can be controlled, which is convenient for controlling the particle size of the medicinal raw materials and improving production efficiency and production quality.

[0015] Furthermore, the cutting blades on the outer surface of the cutting disc and the cutting blades on the inner surface of the cutting cylinder have opposite rotation directions.

[0016] When the cutting knives on the cutting disc and the cutting cylinder rotate in opposite directions, the medicinal materials will be subjected to bidirectional shearing forces between the two. This bidirectional shearing action causes the medicinal materials to be cut in different directions at the same time, 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 gear is 10:1.

[0018] In order to achieve differential movement between the smoothing block and the filter, enhance material dispersion, and make the material more evenly distributed on the filter, differential rotation can make the particles pass through the filter faster and reduce the filtration time. At the same time, the high-speed rotation of the filter can generate a larger centrifugal force, so that the larger particles are quickly thrown to the edge of the filter, reducing the accumulation of large particles in the center area of ​​the filter, thereby reducing the risk of filter blockage.

[0019] Furthermore, the memory spring is stretched to a limit distance which is consistent with the distance between the rolling ball and the filter surface.

[0020] In order to facilitate the grinding of large-particle medicinal materials on the surface of the filter and avoid clogging of the filter, when the memory spring does not receive current, the smoothing block evenly flattens the raw materials on the surface of the filter to improve the filtration efficiency.

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

[0022] In order to facilitate automatic control and timely automatic response of the device, the lifting and lowering of the cutting disc is controlled to control the particle size while grinding the excessively large particles on the filter to avoid clogging of the filter and affecting production efficiency.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, when the crushing leaves in the crushing unit rotate and contact with the pressure plate, the telescopic spring is pushed up to drive the first electrode plate and the second electrode plate to contact each other and compress the telescopic spring, thereby starting the electric telescopic rod. On the other hand, during the intermittent contact between the pressure plate and the crushing leaves, the dust filter cloth is tightened and relaxed so that the medicinal materials on the dust filter cloth can quickly enter the cutting barrel, avoiding blockage caused by the accumulation of raw materials, affecting the crushing efficiency, and ensuring that the feeding rate in the cutting barrel is always stable.

[0025] 2. The present invention forms differential motion with the filter screen through the smoothing block in the adjustment unit. When the filter screen rotates rapidly, the material is more easily diffused to the surface of the filter screen under the action of centrifugal force, so that the material is more evenly distributed on the filter screen. When the pressure sensor detects that the pressure is too large and exceeds the maximum set value, the electromagnet receives the current with the same polarity as the magnet block under the filter screen, pushes the bar magnet and the cutting disc to move upward, reduces the distance with the cutting cylinder, and thus reduces the crushed particle size of the medicinal raw 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, expands and stretches, and causes the rolling ball to grind the medicinal raw materials with large particle sizes on the filter screen to avoid clogging of the filter screen. When the electric telescopic rod receives the positive current from the second electrode plate, the current direction is changed to push the impact block to impact the filter screen, causing the filter screen to vibrate, thereby increasing the filtering speed of the medicinal raw materials that meet the particle size requirements.

The fixed end of the motor 31 is fixedly mounted on the surface of the end of the machine 1 away from the horizontal foundation, the output end of the motor 31 extends into the crushing barrel 2 and is fixedly connected to the driving wheel 32. The driving wheel 32 is connected to the driven wheel 34 through a transmission belt 33. The driven wheel 34 is fixedly mounted on the end of the rotating shaft 35 close to the motor 31. Both ends of the rotating shaft 35 are rotatably mounted on the inner wall of the crushing barrel 2. The crushing wheel 36 is fixedly mounted on the rotating shaft 35. On the outer surface, there are two crushing wheels 36, and multiple groups of crushing leaves 37 are evenly and fixedly installed on the outer surface of the crushing wheel 36.

[0045] When the medicinal material enters the crushing drum 2 through the feeding port of the crushing drum 2, the controller controls the motor 31 to start, thereby driving the driving wheel 32 to rotate, and driving the driven wheel 34 to rotate under the transmission action of the transmission belt 33, so that the rotating shaft 35 drives the left crushing wheel 36 to rotate counterclockwise, so that the left crushing wheel 36 drives the crushing leaves 37 to rotate, and the right crushing wheel 36 and crushing leaves 37 to rotate clockwise, so as to perform preliminary crushing on the falling medicinal material.

A T-shaped slot is provided at one end of the foundation, one end of a round rod 48 is slidably mounted in the T-shaped slot 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 slot of the electromagnet 47, a pinion 49 is fixedly mounted at the telescopic end of the telescopic shaft 42, a gear ring is provided inside the turntable 410, the pinion 49 is meshedly connected with the gear ring of the turntable 410, a smoothing block 411 is fixedly mounted on the surface of one end of the turntable 410 close to the horizontal foundation, a pressure sensor 412 is fixedly mounted on the end of the turntable 410 away from the horizontal foundation, a detection end of the pressure sensor 412 is fixedly mounted on the outer surface of the smoothing block 411, and a memory spring 42 is provided inside the turntable 410.

The filter screen 418 is rotatably installed on the outer surface of the telescopic end of the telescopic shaft 42, and a plurality of groups of magnet blocks are fixedly installed on the filter screen 418 near the horizontal base.

[0047] When the raw materials that have undergone primary crushing enter the cutting cylinder 45, the controller controls the motor 2 41 to start and drive the telescopic shaft 42 to rotate synchronously, thereby driving the cutting disc 44 to rotate in the cutting cylinder 45, and performing secondary crushing on the medicinal raw materials in the cutting cylinder 45. When the telescopic shaft 42 rotates and drives the pinion 49 to rotate, the turntable 410 is driven to rotate slowly along with the round rod 48 on the electromagnet 47. At the same time, the rotation of the turntable 410 drives the smoothing block 411 to rotate, so that the smoothing block 411 and the filter screen 418 form a differential motion. 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, and the smoothing block 411 is relatively The slow rotation can smooth the materials accumulated on the surface of the filter 418, so that the materials are more evenly distributed on the filter 418, so that the medicinal materials can quickly pass through the filter 418 while avoiding the blockage of the filter 418. When the smoothing block 411 rotates, the rapid rotation of the filter 418 makes it easier for the particles with larger particle sizes to be thrown to the edge of the filter 418. When the pressure sensor 412 detects that the pressure is too high and exceeds the maximum set value, it proves that the particle size of the crushed raw material is too large. At this time, the pressure sensor 412 feeds back a signal to the controller, and the controller transmits current to the electromagnet 47, so that the electromagnet 47 is in contact with the magnet block under the filter 418. The same polarity, thereby stretching the telescopic shaft 42 under the action of the repulsive force, thereby driving the bar magnet 43 and the cutting disk 44 to move upward, reducing the distance between the bar magnet 43 and the cutting cylinder 45, thereby reducing the crushing particle size of the medicinal material in the cutting cylinder 45. During the upward movement of the bar magnet 43, the magnetic flux is changed, thereby generating current in the coil 46. When the controller detects that the direction of the current in the coil 46 is positive, it transmits current to the memory spring 413 for a certain period of time, thereby causing the memory spring 413 to expand and elongate, thereby driving the rolling ball 415 under the action of the thin rod 414 to grind the medicinal material with large particle size on the filter screen 418 to avoid clogging of the filter screen 418. 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 raw material passes through the filter 418 too fast. At this time, the controller transmits a reverse current to the electromagnet 47, so that the electromagnet 47 presents the same polarity as the magnet block, and drives the cutting disk 44 and the bar magnet 43 to move downward under the action of attraction, thereby increasing the distance between the cutting disk 44 and the cutting cylinder 45 and increasing the crushed particle size. When the electric telescopic rod 416 receives the forward current from the second electrode plate 314, the current direction is changed to push the impact block 417 to impact the filter 418, causing the filter 418 to vibrate, thereby increasing the filtering speed of the medicinal raw materials that meet the particle size requirements.

[0048] like Figure 4 , 9 As shown in FIG. 11 , the cutting disc 44 is conical, and the diameter of the end close to the horizontal foundation is larger than the diameter of the end away from the horizontal foundation.

[0049] In order to facilitate the smooth entry of the medicinal raw materials into the cutting cylinder 45, while facilitating the cutting disc 44 to change the distance between it and the cutting cylinder 45 during the lifting process, the crushed particle size of the medicinal raw materials can be controlled, which is convenient for controlling the particle size of the medicinal raw materials and improving production efficiency and production quality.

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

[0051] When the cutting knives on the cutting disc 44 and the cutting cylinder 45 rotate in opposite directions, the medicinal material raw material will be subjected to bidirectional shearing force between the two. This bidirectional shearing action causes the medicinal material to be cut in different directions at the same time, greatly improving the crushing efficiency.

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

[0053] In order to achieve differential movement between the smoothing block 411 and the filter screen 418, enhance material dispersion, and make the material more evenly distributed on the filter screen 418, the differential rotation can make the particles pass through the filter screen 418 more quickly, reducing the filtration time. At the same time, the high-speed rotation of the filter screen 418 can generate a larger centrifugal force, so that the particles with larger particle sizes are 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, thereby reducing the risk of clogging of the filter screen 418.

[0054] like Figure 4 As shown, the memory spring 413 is stretched to a limit distance which is consistent with the distance between the rolling 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 the filter 418 and avoid clogging of the filter 418, when the memory spring 413 does not receive current, the smoothing block 411 evenly flattens the materials on the surface of the filter 418 to improve the filtering efficiency.

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

[0057] In order to facilitate automatic control and timely automatic response of the device, the cutting disc 44 is controlled to rise and fall to control the particle size while grinding the excessively large particles on the filter screen 418 to avoid clogging of the filter screen 418 and affecting production efficiency.

[0058] Working principle of the present invention:

[0059] When the medicinal material enters the crushing cylinder 2 through the feeding port of the crushing cylinder 2, the controller controls the motor 31 to start, thereby driving the driving wheel 32 to rotate, and driving the driven wheel 34 to rotate under the transmission action of the transmission belt 33, so that the rotating shaft 35 drives the left crushing wheel 36 to rotate counterclockwise, so that the left crushing wheel 36 drives the crushing leaves 37 to rotate, and the right crushing wheel 36 and crushing leaves 37 to rotate clockwise during the rotation, so as to perform preliminary crushing on the falling medicinal material. When the left and right groups of crushing leaves 37 rotate and contact with the pressure plate 310, the pressure plate 310 is lifted upward, and on the one hand, the telescopic spring 311 is pushed up to drive the first electrode plate 313 and the second electrode plate 314 to contact each other and compress the telescopic spring 311. At this time, the positive current in the first electrode plate 313 flows to the electric telescopic rod 416 through the second electrode plate 314. When the electric telescopic rod 416 receives the positive current of the second electrode plate 314, the electric telescopic rod 416 changes the electric The impact block 417 is pushed to impact the filter screen 418 in the direction of the flow, causing the filter screen 418 to vibrate, thereby increasing the filtering 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 upward along the inner wall of the crushing cylinder 2, and the dust filter cloth 38 is pulled tight, so that the primary crushed medicinal materials accumulated on the dust filter cloth 38 enter the cutting cylinder 45. When the pressing plate 310 is not in contact with the rotating crushing leaves 37, the pressing plate 310 and the elastic ring 39 move downward under the action of gravity. On the one hand, the first electrode plate 313 is disengaged from the second electrode plate 314, disconnecting the transmission of the forward current. On the other hand, the elastic ring 39 descends to make the dust filter cloth 38 wrinkle again. Through the tightening and relaxation 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 blockage caused by raw material accumulation, affecting the crushing efficiency, and 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 controls the motor 2 41 to start and drive the telescopic shaft 42 to rotate synchronously, thereby driving the cutting disc 44 to rotate in the cutting cylinder 45, and performing secondary crushing on the medicinal materials in the cutting cylinder 45. When the telescopic shaft 42 rotates and drives the small gear 49 to rotate, the turntable 410 is driven to rotate slowly along with the round rod 48 on the electromagnet 47. At the same time, the rotation of the turntable 410 drives the smoothing block 411 to rotate, so that the smoothing block 411 and the filter screen 418 form a differential motion. When the filter screen 418 rotates quickly, the material is more easily moved under the action of centrifugal force. The surface of the filter 418 diffuses, and the smoothing block 411 rotates at a relatively slow speed, which can smooth the materials accumulated on the surface of the filter 418, so that the materials are more evenly distributed on the filter 418, so that the medicinal materials can quickly pass through the filter 418 while avoiding the blockage of the filter 418. When the smoothing block 411 rotates, the rapid rotation of the filter 418 makes it easier for the larger particles to be thrown to the edge of the filter 418. When the pressure sensor 412 detects that the pressure is too large and exceeds the maximum set value, it proves that the particle size of the crushed raw material is too large. At this time, the pressure sensor 412 moves to The controller feeds back a signal, and the controller transmits current to the electromagnet 47, so that the electromagnet 47 and the magnet block under the filter 418 have the same polarity, so that the telescopic shaft 42 is stretched under the action of the repulsive force, thereby driving the bar magnet 43 and the cutting disk 44 to move upward, reducing the distance between the bar magnet 43 and the cutting cylinder 45, thereby reducing the crushed particle size of the medicinal material in the cutting cylinder 45. During the upward movement of the bar magnet 43, the magnetic flux is changed, thereby generating current in the coil 46. When the controller detects that the direction of the current in the coil 46 is positive, it transmits current to the memory spring 413 for a certain period of time, so that The memory spring 413 expands and stretches, thereby driving the crushing ball 415 to grind the medicinal raw materials with large particle size on the filter 418 under the action of the thin rod 414 to avoid clogging of the filter 418. 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 raw material passes through the filter 418 too fast. At this time, the controller transmits a reverse current to the electromagnet 47, so that the electromagnet 47 presents the same polarity as the magnet block, and drives the cutting disk 44 and the bar magnet 43 downward under the action of attraction, thereby increasing the distance between the cutting disk 44 and the cutting cylinder 45 and increasing the crushed particle size.
