Description

Technical Field

[0001] The invention relates to the technical field of drug pulverization, and in particular to an energy-saving raw material pulverization device for drug production and a use method thereof. Background Art

[0002] The production process of traditional Chinese medicine is a complex and delicate process involving multiple steps, including raw material collection, cleaning and pretreatment, crushing and pulverizing, extraction and concentration. The pulverizing step is to pulverize the slices or sections of the traditional Chinese medicine to increase the extraction rate of the effective ingredients of the traditional Chinese medicine, improve the efficacy and increase the stability of the medicine. Generally, ball mills, vibration mills, toothed disc mills, etc. are used.

[0003] In the process of crushing Chinese medicine by a toothed disc grinder, the internal toothed disc and the crushing parts rotate relative to each other to squeeze and shear the Chinese medicine, so as to complete the crushing of the Chinese medicine. When crushing Chinese medicine containing fiber, due to the high toughness of the fiber, the fiber cannot be completely crushed by squeezing and shearing between the toothed disc and the crushing parts. In the process of crushing, the fiber will also cause the drug particles to entangle and wrap, and the drug particles will not be able to fully contact with the toothed disc or the crushing parts, so that the wrapped drug can no longer be crushed, resulting in the need to extend the use time of the grinder to ensure that the Chinese medicine is completely crushed and qualified, wasting too much time, and the long-term operation of the machine also wastes resources.

DETAILED DESCRIPTION

[0038] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0039] Through research, it is found that when using a toothed disc pulverizer to pulverize traditional Chinese medicine containing fibers, the fibers in the traditional Chinese medicine cannot be fully pulverized. At the same time, during the rotation of the toothed disc, the fibers will wrap other traditional Chinese medicine particles, making it impossible for the wrapped traditional Chinese medicine to fully contact the toothed disc. At the same time, the fibers gather together to have a certain buffering effect, so that the wrapped traditional Chinese medicine cannot be crushed by the impact of the toothed disc, which leads to a decrease in the efficiency of traditional Chinese medicine pulverization. If qualified traditional Chinese medicine is obtained, the pulverizer needs to work for a long time, which will waste resources. In view of the above situation, an energy-saving raw material pulverization device for drug production is hereby proposed. The specific scheme is as follows:

[0040] like Figure 1-Figure 8 As shown, it includes: a frame 1; a crusher body 2, which is installed on the frame 1 and is used to crush materials, and a screening plate 21 is fixedly connected to one side of the crusher body 2; a cyclone separator 3, which is installed on one side of the frame 1, and the cyclone separator 3 is connected to the upper side of the crusher body 2, and is used to screen the crushed materials; an air duct 4, which is installed on the frame 1, one end of which is connected to the lower side of the crusher body 2, and the screening plate 21 is located at the connection point, and the other end is connected to the peripheral side of the crusher body 2, and the frame 1 is installed with a fan 5, and the fan 5 is connected to the air duct 4, and is used to blow the inside of the crusher body 2 Material circulation; a fixed plate 6, rotatably connected to the pulverizer body 2, the fixed plate 6 is fixed with circumferentially distributed pulling blocks 7, which are used to tear the material; a cutting block 8, which has a number of circumferentially distributed and is consistent with the number of pulling blocks 7, is rotatably connected to the fixed plate 6, and is used to cut the material, and the cutting block 8 is slidably connected to the adjacent pulling block 7; a driving component, arranged on the frame 1, is used to drive the fixed plate 6 to rotate; a trigger component, arranged on the fixed plate 6, is used to drive the cutting block 8 to rotate; a tightening mechanism, arranged on the air duct 4, is used to squeeze the material.

[0041] Specifically, the pulling block 7 has comb-shaped support rods that are evenly distributed, which are used to tear the material, and the cutting block 8 is provided with equidistantly distributed protrusions, which are staggered and fit together with the support rods. The pulling block 7 and the cutting block 8 are both provided with inclined surfaces with opposite inclination directions, so that the edges of the two are in the same plane after they are fitted together.

[0042] In the above scheme, the problem that the existing toothed disc pulverizer cannot fully pulverize the traditional Chinese medicine containing fiber is solved. The pulverizer body 2 is an existing toothed disc pulverizer, and the pulverizer body 2 includes a driving motor 22 (installed on the frame 1, which is an existing servo motor, providing power for the rotation of its internal parts), a crushing frame 23 (the crushing frame 23 is fixedly connected to the output shaft of the driving motor 22), circumferentially distributed crushing blocks 24 (fixedly connected to the inner wall of the shell of the pulverizer body 2) and a feeding frame 25; the screening plate 21 is located on the lower side of the pulverizer body 2, so that the traditional Chinese medicine that is not completely pulverized falls downward, which is convenient for subsequent circulation pulverization; the cyclone separator 3 is an existing device, and its purpose is to absorb the qualified traditional Chinese medicine into it through negative pressure and screen it; the outer wall of the air duct 4 can be A vibration motor is installed to prevent the Chinese medicine from adhering to the inner wall during the passage; the fan 5 is an existing device, which ensures that the air inside the air duct 4 is always in a flowing state, which is convenient for the flow and circulation of the Chinese medicine. The Chinese medicine entering the air duct 4 is the Chinese medicine that has not been completely crushed, mainly block-shaped Chinese medicine and fiber materials; the power of the cyclone separator 3 is greater than the power of the fan 5, which ensures that qualified Chinese medicine can smoothly enter the cyclone separator 3; the pulling block 7 and the cutting block 8 are made of wear-resistant metal to increase their service life. When the device is initially used, the pulling block 7 and the cutting block 8 fit together, and their function is consistent with that of the crushing block 24. The pulling block 7 is provided with an inwardly concave arc surface, and the cutting block 8 is provided with an outwardly convex arc surface. The arc surfaces of the two can fit together and are at the same center.

[0043] Working process: When the Chinese medicine is crushed, the Chinese medicine is put into the grinder body 2 from the feeding rack 25, the driving motor 22 works and drives the crushing rack 23 to rotate, and the crushing rack 23 and the crushing block 24 rotate relative to each other (in the initial stage, the crushing rack 23 cooperates with the pulling block 7 and the cutting block 8 that fit each other), and the Chinese medicine in the grinder body 2 is squeezed, sheared and impacted, so as to crush the completed Chinese medicine. In this process, the cyclone separator 3 works and draws qualified Chinese medicine into it, and screens the Chinese medicine. At the same time, the fan 5 works to blow air to the upper part of the air duct 4, so that the air duct 4 and the grinder body 2 form a complete flow channel, which is convenient for the Chinese medicine to flow in the air duct 4. The Chinese medicine in the grinder body 2 that cannot fully contact with the crushing rack 23 passes through the screening plate 21 into the air duct 4 under the action of gravity, and re-enters the grinder body 2 from the left side along the air duct 4, and the unqualified Chinese medicine is crushed again, so as to realize the cycle of Chinese medicine crushing.

[0044] After the driving motor 22 has been working for a period of time (after the large pieces of Chinese medicine are crushed into small pieces), the user controls the cutting block 8 to rotate through the driving component and the trigger component, so that the cutting block 8 is misaligned with the pulling block 7, and the support rod of the pulling block 7 applies a pulling force to the Chinese medicine, and at the same time tears the clumped Chinese medicine fibers to separate the clumped fibers, and at the same time exposes the Chinese medicine wrapped in the fibers, so that the Chinese medicine is re-contacted with the crushing frame 23, increasing the contact area with the crushing frame 23, and facilitating the crushing of the Chinese medicine. The inclined surface of the cutting block 8 cuts the Chinese medicine and its fibers, speeding up the crushing speed of the Chinese medicine. At the same time, the cutting block 8 and the pulling block 7 that are misaligned with each other increase the space occupied by the two, and reduce the distance between them and the crushing frame 23, thereby improving the effect of crushing the Chinese medicine passing through the three. Through the action of the above-mentioned cutting block 8 and the pulling block 7 on the Chinese medicine, the overall crushing time of the Chinese medicine is shortened, and the crushing efficiency is improved.

[0045] After the cutting block 8 and the pulling block 7 are misaligned for a period of time, the user controls the cutting block 8 to rotate in the opposite direction through the driving component and the trigger component, so that the cutting block 8 and the pulling block 7 are re-fitted. During the relative rotation of the cutting block 8 and the pulling block 7, the protrusions on the cutting block 8 squeeze the Chinese medicine fibers remaining on the support rods of the pulling block 7, so that the fibers on the support rods of the pulling block 7 are detached, and too many fibers are prevented from being entangled on the support rods of the pulling block 7, which affects the crushing effect. Then, the cutting block 8 and the pulling block 7 are misaligned with each other again, and this is repeated. After the Chinese medicine is crushed through multiple cycles, after the Chinese medicine is crushed in the crusher body 2, the user turns off all the above-mentioned electrical components.

[0046] Specifically, Figure 3 , Figure 6 and Figure 8 As shown, the driving assembly includes: a first driving member 201, which is installed on the frame 1, and the power output end of the first driving member 201 is transmitted to the fixed plate 6 through a gear set; a synchronous frame 202, which is fixed to the fixed plate 6; a centrifugal block 203, which has a plurality of evenly distributed centrifugal blocks 203 and is slidably connected to the synchronous frame 202, and a tension spring is provided between the centrifugal block 203 and the synchronous frame 202.

[0047] Specifically, Figure 3 , Figure 6-Figure 8 As shown, the trigger assembly includes: a trigger plate 301, which is slidably connected to the fixed plate 6, the centrifugal block 203 is pressed and matched with the trigger plate 301, and a spring is arranged between the trigger plate 301 and the fixed plate 6; a plurality of limit posts 302, which are circumferentially distributed and the number is consistent with the cutting block 8, are fixed to the trigger plate 301, and the cutting block 8 is pressed and matched with the adjacent limit posts 302 to drive the cutting block 8 to rotate.

[0048] In the above scheme, the purpose is to provide power for the fixed plate 6 to achieve the effect of accelerating the speed of crushing the Chinese medicine. The first driving member 201 is a servo motor, which is convenient for controlling the rotation of the fixed plate 6, and the rotation direction of the first driving member 201 is consistent with the driving motor 22, so that the rotation direction of the crushing frame 23 is opposite to the rotation direction of the fixed plate 6, thereby improving the crushing effect of the Chinese medicine; the centrifugal blocks 203 are uniformly distributed in the circumference, so as to improve the stability of the fixed plate 6 when rotating, and the back side of the uniform centrifugal blocks 203 is provided An inclined surface is provided to facilitate squeezing the trigger plate 301 to move it; the inner side of the trigger plate 301 is set as an inclined surface, which is also convenient for being squeezed by the centrifugal block 203; an arc-shaped protrusion is provided on the outer side of the limiting column 302, and an arc-shaped inclined groove is provided on the inner side of the cutting block 8. The limiting column 302 squeezes the cutting block 8, and the arc-shaped protrusion of the limiting column 302 slides along the inclined groove of the cutting block 8 to rotate the cutting block 8. The central axis of the limiting column 302 coincides with the axis of the arc-shaped surface of the cutting block 8 and the axis of the arc-shaped surface of the pulling block 7.

[0049] Working process: After the driving motor 22 has worked for a period of time, the user starts the first driving member 201 at a fixed time, and the power output end of the first driving member 201 drives the fixed plate 6 to rotate through the gear set (due to the transmission of the gear set, the rotation direction of the fixed plate 6 is opposite to the rotation direction of the crushing frame 23). During the rotation of the fixed plate 6, under the action of centrifugal force, the centrifugal block 203 moves outward and stretches the tension spring thereon, and at the same time, the centrifugal block 203 squeezes the trigger plate 301, and the trigger plate 301 is pressed to move inwardly of the fixed plate 6 and compress the spring thereon, and the trigger plate 301 drives the limiting column 302 thereon to move, and the limiting column 302 moves relative to the cutting block 8 and causes the cutting block 8 to rotate, and the cutting block 8 rotates relative to the pulling block 7, and the support rod of the pulling block 7 is misaligned with the cutting block 8 (such as Figure 5 The state of the upper cutting block 8 and the pulling block 7), during the rotation of the pulling block 7, the support rod thereon intercepts and tears the Chinese medicine fiber material, and at the same time the pulling block 7 rotates in the opposite direction, increasing the impact force between the Chinese medicine thereon and the crushing frame 23, so that it is quickly crushed, and the first driving member 201 is closed after working for a period of time, and the pulling block 7 and the cutting block 8 are re-fitted, and then the first driving member 201 is reopened, and the pulling block 7 and the cutting block 8 are misaligned, and this is repeated until the Chinese medicine is crushed. The first driving member 201 is closed, and the centrifugal block 203 is reset under the action of the tension spring to lose the squeeze on the trigger plate 301, and the trigger plate 301 is reset under the action of the spring thereon, and the cutting block 8 and the pulling block 7 are re-fitted and reset.

[0050] Specifically, Figure 9-11As shown, the tightening mechanism includes: a support plate 401, installed on the air duct 4 and located below the screening plate 21; an extrusion coil spring 402, installed on the support plate 401, used to extrude the material; a partition plate 403, slidably connected to the air duct 4, used to block the air duct 4; a transmission assembly, arranged on the frame 1, used to deform the extrusion coil spring 402 and drive the partition plate 403 to move.

[0051] Specifically, Figure 9-11 As shown, the transmission assembly includes: a second driving member 501, which is installed on the frame 1, and the frame 1 is fixedly connected with a fixed base 502, the fixed base 502 has a first limiting portion 5021, a second limiting portion 5022 and a third limiting portion 5023, the partition plate 403 is slidably connected to the fixed base 502, the first limiting portion 5021 and the second limiting portion 5022 are both limited by the partition plate 403, and the second limiting portion 5022 and the third limiting portion 5023 are both limited by the extrusion coil spring 402; a limiting block 503, which is slidably connected to the power output end of the second driving member 501, and a spring is installed between the power output end of the second driving member 501, and the extrusion coil spring 402 and the partition plate 403 are both limited by the limiting block 503.

[0052] In the above scheme, the purpose is to gather together the Chinese medicine that cannot fully contact the crushing frame 23 and is located in the air duct 4 (this part of the Chinese medicine includes block-shaped Chinese medicine and some fiber materials), change the shape of the circulating Chinese medicine, and make the circulating Chinese medicine easy to crush. The second driving member 501 can be an electric push rod or a hydraulic push rod, and any device that allows the limit block 503 to move back and forth can be used. This device can be flexibly changed according to actual conditions; the extrusion coil spring 402 can be an existing coil spring, which has its own elasticity and is convenient for its own reset; a sealing gasket is provided at the sliding connection between the partition plate 403 and the air duct 4 to improve the sealing of the two and prevent the Chinese medicine from being dispersed from between the two to the outside, causing waste of Chinese medicine. The limit block 503 is provided with two symmetrically distributed inclined surfaces, which are convenient for extrusion and cooperation with the extrusion coil spring 402 and the partition plate 403, and compress the spring on it.

[0053] Workflow: During the process of crushing the Chinese medicine, the un-crushed Chinese medicine falls into the air duct 4 under the action of its own gravity. In the initial state, the partition plate 403 is located at the lower side of the squeezing coil spring 402, and the air duct 4 is blocked to intercept the Chinese medicine falling into the air duct 4, so that the falling Chinese medicine enters the squeezing coil spring 402, and the Chinese medicine gradually accumulates in the squeezing coil spring 402. The orientations in the following workflow are all based on Fig.10 described.

[0054] After a period of time, the second driving member 501 is turned on at a fixed time, and the power output end of the second driving member 501 extends out and drives its upper limit block 503 to move forward (the limit block 503 is initially located at the second limit portion 5022), and the limit block 503 contacts and squeezes the extrusion coil spring 402. The extrusion coil spring 402 cannot move due to the obstruction of the third limit portion 5023. The limit block 503 moves downward under the action of the extrusion coil spring 402 and compresses the spring thereon. After the limit block 503 passes the extrusion coil spring 402, the limit block 503 moves upward under the action of the spring thereon. Then the power output end of the second driving member 501 is retracted and drives the extrusion coil spring 402 to tighten through the limit block 503. The extrusion coil spring 402 squeezes the block-shaped Chinese medicine and part of the fiber material inside it, so that the Chinese medicine inside is compressed and gathered together, making the Chinese medicine fiber material more compact, which is convenient for subsequent contact with the crushing frame 23 to speed up the speed of Chinese medicine crushing.

[0055] During the process of the limit block 503 moving backward, the extrusion coil spring 402 contacts the second limit part 5022 and cannot move, the limit block 503 moves downward and compresses the spring thereon, after the limit block 503 passes through the extrusion coil spring 402, the extrusion coil spring 402 is reset under the action of its own elastic force and contacts the third limit part 5023 again, and the limit block 503 moves upward at the same time, and then the limit block 503 contacts the partition plate 403 and drives it to move backward, the bottom of the compressed Chinese medicine in the extrusion coil spring 402 loses support and moves downward, continues to enter the grinder body 2 along the air duct 4, and contacts the crushing frame 23 again.

[0056] As the partition plate 403 moves, when the partition plate 403 contacts the first limit portion 5021, the partition plate 403 stops moving, the limit block 503 moves downward and compresses the spring thereon, and after the limit block 503 passes the partition plate 403, the limit block 503 moves upward, and the power output end of the second drive member 501 moves forward.

[0057] The power output end of the second driving member 501 drives the limit block 503 to move forward, and drives the partition plate 403 to move forward. After the partition plate 403 contacts the second limit portion 5022, the partition plate 403 stops moving and re-blocks the air duct 4. The limit block 503 continues to move forward and passes through the partition plate 403. After the limit block 503 is aligned with the second limit portion 5022, the second driving member 501 stops working. At this time, a polymerization of the Chinese medicine fiber material and the block Chinese medicine is completed. Subsequently, the second driving member 501 is turned on at a fixed time and the above operation is repeated.

[0058] Further, such as Fig. 9 , Figure 12-14As shown, it also includes: a kneading mechanism, which is arranged in the air duct 4 and is used to knead the material; the kneading mechanism includes a mounting plate 601, which is fixed in the air duct 4; a kneading frame 602, which is slidably connected to the mounting plate 601, and the kneading frame 602 is squeezed and matched with the air duct 4 to knead the material; a moving component, which is arranged on the frame 1 and is used to drive the kneading frame 602 to move.

[0059] The above scheme aims to further increase the compactness of the Chinese medicine in the air duct 4, make the Chinese medicine polymerized in the above scheme more compact, and further change its shape, so that the Chinese medicine is more convenient to contact with the crushing frame 23; the lower side of the kneading frame 602 is set to a frosted surface, which increases the contact friction between the kneading frame 602 and the Chinese medicine, making it easier to knead the Chinese medicine. A shielding plate is set on the left side of the kneading frame 602, so that the lower part of the kneading frame 602 is L-shaped, and a blocking block is set on the left side of the middle part of the air duct 4. The shielding plate and the shielding block slide with each other and always fit together. The shielding plate and the shielding block cooperate with each other to always block the air duct 4, so as to prevent the Chinese medicine in the air duct 4 from entering the upper side of the kneading frame 602 (here Fig.12 for example).

[0060] Specifically, Fig. 9 , Figure 12-14 As shown, the moving component includes: a third driving member 701, which is installed on the frame 1, and the power output end of the third driving member 701 is fixedly connected to the driving wheel 702, and the power output end of the third driving member 701 is rotatably connected to the air duct 4, and the driving wheel 702 is located in the air duct 4; an extrusion frame 703, which is rotatably connected to the eccentric part of the driving wheel 702, the extrusion frame 703 is extruded and matched with the kneading frame 602, the extrusion frame 703 is slidably connected to a plurality of sliding frames 704, a spring is arranged between the sliding frame 704 and the kneading frame 602, the sliding frame 704 is slidably connected to a plurality of sliding plates 705, a spring is arranged between the sliding plate 705 and the sliding frame 704, and the sliding frame 704 and the sliding plate 705 are both extruded and matched with the extrusion frame 703.

[0061] In the above scheme, the third driving member 701 is a servo motor; two driving wheels 702 are provided, and one of them is fixedly connected to the power output end of the third driving member 701, and the two driving wheels 702 are connected by a belt, so that the force on the extrusion frame 703 is balanced, thereby ensuring the stability of the extrusion frame 703 when moving; the contact surface between the extrusion frame 703 and the sliding frame 704 and the sliding plate 705 is set with a smooth surface to reduce mutual wear; a plurality of sliding frames 704 and a plurality of sliding plates 705 make the kneading frame 602 evenly stressed and improve its stability.

[0062] The mounting plate 601 is provided with a limiting groove, and the kneading frame 602 is located in the limiting groove and slides. The limiting groove is a right-angle trapezoid, which is used to limit the movement of the kneading frame 602 so that the kneading frame 602 forms a kneading action with the air duct 4.

[0063] Workflow: When crushing the traditional Chinese medicine, the user turns on the third driving member 701, and the power output end of the third driving member 701 drives the driving wheel 702 thereon to rotate, and the driving wheel 702 drives another driving wheel 702 to rotate through a belt, and the two driving wheels 702 synchronously drive the extrusion frame 703 to reciprocate.

[0064] For ease of understanding, the following content is based on Fig.12 The kneading frame 602 is initially along the upper horizontal groove of the limiting groove of the mounting plate 601. During the counterclockwise rotation of the extrusion frame 703, the extrusion frame 703 drives the kneading frame 602 to slide to the left along the upper side of the limiting groove of the mounting plate 601. At the same time, the extrusion frame 703 squeezes the sliding frame 704 on the left side to compress the spring on the sliding frame 704, and then slides along the left vertical groove of the limiting groove of the mounting plate 601. The lower side of the kneading frame 602 contacts the air duct 4 and squeezes the Chinese medicine therebetween. After the Chinese medicine passes through the squeezing coil spring 402, the air in the air duct 4 is Under the action of the flow, it enters the middle part of the air duct 4. In this process, the extrusion frame 703 squeezes the sliding plate 705 on the lower side, causing it to move downward and compress the spring thereon. The compressed spring here always provides a downward force to the kneading frame 602, so that the kneading frame 602 can fully squeeze the Chinese medicine. Then the extrusion frame 703 drives the kneading frame 602 to move to the right, and the kneading frame 602 slides along the lower horizontal groove of the limiting groove of the mounting plate 601. The extrusion frame 703 squeezes the right sliding frame 704 to compress the spring on the sliding frame 704 (at this time, the left sliding frame 704 is reset under the action of the spring).

[0065] When the kneading frame 602 moves to the right, the kneading frame 602 rubs the fiber material of the Chinese medicine on its lower side, and drives the fiber material of the Chinese medicine to rotate between the kneading frame 602 and the air duct 4 through friction. With the rotation and the squeezing of the kneading frame 602, the fiber material of the Chinese medicine is gradually tightened, so that the fiber material of the Chinese medicine is formed into long strips, thereby increasing the length of the fiber material of the Chinese medicine, facilitating the contact between the fiber material of the Chinese medicine and the crushing frame 23, and accelerating the crushing speed of the fiber material of the Chinese medicine.

[0066] As the kneading frame 602 moves to the right, the squeezing frame 703 then drives the kneading frame 602 to move upward, and the kneading frame 602 slides along the right side oblique groove of the limiting groove of the mounting plate 601, and at the same time the squeezing frame 703 squeezes the upper sliding plate 705 (the lower sliding plate 705 is reset under the action of the spring), after the kneading frame 602 moves to the upper side of the right side oblique groove of the limiting groove of the mounting plate 601, the squeezing frame 703 drives the kneading frame 602 to move to the left, and repeats the above process to knead the Chinese medicine in the air duct 4 until the Chinese medicine is crushed, and then the third driving member 701 is closed.

[0067] Furthermore, this embodiment provides a method for using an energy-saving raw material crushing device for drug production, which can be applied to an energy-saving raw material crushing device for drug production in the above embodiment to crush traditional Chinese medicine. The method for using the method has the following steps:

[0068] Step 1: Put the Chinese medicine into the pulverizer body 2, start the pulverizer body 2, and pulverize the Chinese medicine therein, and turn on the cyclone separator 3 and the fan 5 to collect qualified Chinese medicine and circulate unqualified Chinese medicine;

[0069] Step 2: After the pulverizer body 2 has been working for a period of time, the first driving member 201 is turned on, and the power output end of the first driving member 201 drives the fixed plate 6 to rotate through the gear set, and the centrifugal block 203 squeezes the trigger plate 301, so that the cutting block 8 and the pulling block 7 rotate relative to each other and are misaligned, and the support rod of the pulling block 7 tears the Chinese medicine;

[0070] Step 3: The second driving member 501 is turned on at a fixed time, and the power output end of the second driving member 501 drives the extrusion coil spring 402 to tighten through the limit block 503, so that the extrusion coil spring 402 squeezes the Chinese medicine therein;

[0071] Step 4: Turn on the third driving member 701, and the power output end of the third driving member 701 drives the kneading frame 602 to reciprocate through the driving wheel 702 and the extrusion frame 703 to knead the Chinese medicine;

[0072] Step 5: After the material is crushed, the crusher body 2, the cyclone separator 3, the fan 5, the first driving member 201, the second driving member 501 and the third driving member 701 are turned off.
