Description

Technical Field

[0001] This application relates to the field of grinding technology, specifically to a device and method for pulverizing and grinding medicinal peony petals. Background Technology

[0002] To improve the utilization rate of peony petals' medicinal properties, accelerate drug dissolution, and enhance bioavailability, ultrafine pulverization technology for traditional Chinese medicine is employed. This technology, adhering to the principles of traditional Chinese medicine, utilizes mechanical or hydrodynamic methods to pulverize medicinal materials and extracts into micron- or even nano-sized powders. To minimize the loss of effective components in peony during processing, this application involves low-temperature drying of the peony flowers before pulverization and grinding.

[0003] A steam-jet pulverizer is a device that uses the energy of high-speed airflow or superheated steam to cause material particles to impact, collide, and rub against each other, thus achieving ultrafine pulverization. The steam-jet pulverizer mainly consists of a pulverizing gas inlet, pulverizing nozzles, a gas equalization chamber, wear-resistant liners, a feed hopper, an air inlet, and a discharge outlet. The operating principle is as follows: ultra-high-pressure gas is injected through a venturi tube to create a negative pressure zone, drawing powder from the hopper and conveying it to the pulverizing chamber; gas or steam is introduced through the main inlet and tangentially accelerated into a supersonic airflow through the nozzles; the airflow carries the material at high speed along the tangential direction, causing the material to collide and pulverize; materials with high centrifugal force move on the outer side, while particles of the required size converge towards the center and are sent to the filter bag through the discharge outlet. The final product has a reasonable particle size, better shape and smoothness, and excellent product quality.

[0004] The aforementioned air-jet powder mill achieves real-time control of powder fineness by adjusting the force of the jet airflow. However, changes in airflow force affect the subsequent flow of powder, which in turn affects subsequent processing steps, making it very inconvenient to use. Moreover, unqualified materials cannot be recycled and processed in real time during the processing, often clogging the filter screen and affecting production efficiency.

[0005] Therefore, it is necessary to provide a device and method for pulverizing and grinding medicinal peony petals to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a device and method for pulverizing and grinding medicinal peony petals, which achieves the effect of real-time control of the fineness of the powder without changing the airflow intensity.

[0008] The technical solution adopted by this application to solve its technical problem is: a medicinal peony petal crushing and grinding device, including a grinding mechanism, a crushing mechanism, and a sieving and recycling mechanism; the output end of the crushing mechanism is connected to the grinding mechanism through a pipeline, the sieving and recycling mechanism is located above the grinding mechanism, and the output end of the grinding mechanism is connected to the sieving and recycling mechanism through a pipeline; wherein, the crushing mechanism separates the petals from the calyx and performs preliminary crushing of the petals, which are then conveyed by wind to the grinding mechanism for powder refinement, and then collected after passing through the sieving and recycling mechanism, which can sieve out unqualified powder and return it to the grinding mechanism for secondary processing.

[0009] The grinding mechanism includes a wear-resistant bed, multiple grinding cylinders, multiple control components, and an adjustment component. The bottoms of the multiple grinding cylinders are hinged to the wear-resistant bed, and the multiple grinding cylinders are arranged circumferentially on the wear-resistant bed. The control components and adjustment component are located below the wear-resistant bed, and the multiple control components are arranged circumferentially around the adjustment component. The support ends of the adjustment component are connected to the control component via ball joints. Each control component corresponds to a grinding cylinder and is connected to it via a control rope. The adjustment component controls the synchronous operation of multiple control components, which in turn controls the synchronous movement of the corresponding grinding cylinders. Under the control of the control components, the grinding cylinders can rotate on the wear-resistant bed. The change in the angle between the grinding cylinder and the wear-resistant bed is proportional to the degree of directional interference to the flowing material. A greater degree of interference results in more collisions between materials, thus increasing the fineness of the material and enabling real-time control of powder coarseness.

[0010] Furthermore, the grinding cylinder includes a cylinder body and a winding device. Rope holes are respectively opened on both sides of the cylinder body. The winding device is located inside the cylinder body, and the cylinder body is equipped with a mounting frame to suspend the winding device. Adjustment ropes are fixedly connected to both sides of the winding device. The other end of the adjustment rope passes through an adjacent rope hole and is fixedly connected to the wear-resistant machine. The side of the winding device is wound around the middle section of the control rope. The mounting frame includes two mounting plates and a mounting bracket. The mounting plates are L-shaped plates, arranged back-to-back and connected by a connecting bracket. One mounting plate is fixedly connected to the mounting bracket on the side away from the connecting bracket, and the mounting bracket is fixedly connected to the cylinder body on the side away from the corresponding mounting plate. The side of the winding device is connected to the mounting plate via a bearing. Thus, the corresponding control component controls the rotation of the winding device via the control rope. The rotating winding device winds one adjustment rope and unwinds the other adjustment rope. The rotation of the cylinder body is controlled by the tension difference between the two adjustment ropes.

[0011] Furthermore, the control rope is made of high-performance polyethylene material, and the adjustment rope is formed by winding steel wire; thus, the control rope has high deformation force and is resistant to low temperature and wear. The control rope drives the take-up and release device to rotate through elastic deformation and friction force; the adjustment rope is not easily deformed and has high toughness.

[0012] Furthermore, the take-up and retractor includes a rotating shaft, a wire control wheel, and two wire locking keys; the wire control wheel is fixedly installed in the middle of the rotating shaft, and the two wire locking keys are fixedly installed on the side of the rotating shaft, with the wire control wheel located between the two wire locking keys; the rotating shaft passes through two mounting plates and is connected by bearings; the wire control wheel is located between the two mounting plates, and the two mounting plates are located between the two wire locking keys; the side of the wire control wheel is wound and connected to the middle section of the control rope, and the end faces of the two wire locking keys are respectively fixedly connected to adjustment ropes, with the other end of the adjustment rope passing through rope hole one and fixedly connected to the wear-resistant machine; thus, the control component pulls back and forth by manipulating both ends of the control rope, causing the middle section of the control rope to control the rotation of the wire control wheel, thereby causing the rotating shaft to rotate synchronously, with one adjustment rope wound around the rotating shaft and the other adjustment rope gradually unwinding from the rotating shaft, thus the length of the adjustment rope at the wound point gradually shortens, pulling the cylinder body to rotate in the tightening direction.

[0013] Furthermore, the wear-resistant bed consists of a fixed plate and a dustproof plate, with the fixed plate located below the dustproof plate. The dustproof plate is made of polyethylene material. The top of the fixed plate has multiple pairs of movable slots and multiple pairs of rope holes, with each pair of rope holes corresponding to a pair of movable slots, and the rope holes located between the movable slots. The movable slots and rope holes are arranged circumferentially. The cylinder is located on top of the fixed plate, and the bottom of the cylinder has a pair of hinge frames, each corresponding to a movable slot and installed within the movable slot. The two ends of the control rope pass through the corresponding rope holes to reach the control assembly. The adjustment rope is located outside the cylinder. The cylinder is fixedly connected to the fixed plate at one end, with one of the control ropes located at one end of the corresponding movable groove and the other control rope located at the other end of the corresponding movable groove. The end of the cylinder away from the fixed plate passes through the dustproof plate, and the side of the cylinder is fixedly connected to the dustproof plate. The axis of the cylinder is tangent to the material direction and opposite to the material direction. After the material enters the equalization chamber, it is spirally moved on the dustproof plate and then output from the output end. When the angle between the cylinder and the fixed plate is the smallest, the plane of the dustproof plate is in an extended state. When the angle between the cylinder and the fixed plate increases, the cylinder pulls the dustproof plate to deform, and the end face of the dustproof plate presents multiple arc ribs, so that more material impacts the dustproof plate for crushing and grinding.

[0014] Furthermore, the grinding mechanism also includes a pressure equalization chamber and an end cap; the end cap is located above the pressure equalization chamber and is connected by a transition fit; a lower ring frame is fixedly installed inside the pressure equalization chamber; multiple inclined grooves are evenly opened at the top of the lower ring frame; multiple pulverizing nozzles are circumferentially arranged on the side of the pressure equalization chamber; one end of each pulverizing nozzle is located inside the pressure equalization chamber and is located within an inclined groove; the wear-resistant bed is located inside the lower ring frame and is fixedly connected to the lower ring frame on its side; the control component and the adjustment component are located inside the pressure equalization chamber and are fixedly connected to the pressure equalization chamber at their bottom; an upper ring frame is provided at the bottom of the end cap; an inclined groove is opened at the bottom of the upper ring frame; the inclined groove is fitted with an inclined groove to fix the pulverizing nozzle; the pulverizing nozzle is higher than the wear-resistant bed; an output pipe is opened at the center of the top of the end cap; one end of the output pipe is connected to the screening and recovery mechanism through a pipeline.

[0015] Furthermore, the control assembly includes a base and a control rod; the bottom of the base is fixedly connected to the equalizing chamber, and two wire seats are installed on one side of the top of the base. The control rod is located between the two wire seats, with one end of the control rod hinged to the center of the top of the base, and the end of the control rod away from the base connected to the control assembly via a ball joint; wire buckles are fixedly installed on both sides of the control rod, and the end of the control rope passes through the corresponding wire seat and is fixedly connected to the wire buckle on the same side; thus, the control assembly manipulates the control rod to swing, and the wire buckle drives the end of the control rope to move, so that the control rope achieves a pulling and rotating effect on the retractor.

[0016] Furthermore, the control component includes a base, a servo motor, and a control disk. The bottom of the base is fixedly connected to the equalizing chamber. The servo motor is fixedly installed in the center of the base, and the output end of the servo motor away from the base is fixedly connected to the control disk. The end face of the control disk is circumferentially provided with multiple sliding grooves. Multiple slide rails are fixedly installed on the top of the base, and the slide rails are circumferentially arranged. The top of each slide rail is slidably connected to a sliding seat. A pull rod and a sliding key are fixedly installed on the top of the sliding seat away from the base. The sliding seat, pull rod, and sliding key are located between the control disk and the base. The sliding key corresponds one-to-one with the slide groove, and the end of the sliding key away from the base and the corresponding slide groove form a mating mechanism. The end of the pull rod away from the sliding seat is connected to the corresponding control rod through a ball joint. Thus, the servo motor causes the control disk to rotate, the slide groove controls the sliding seat to slide on the slide rail through the sliding key, and the pull rod drives the control rod to swing.

[0017] Furthermore, two impellers are hinged to the outer side of the cylinder body above the dustproof plate. The two impellers are symmetrically arranged and are not on the same side as the rope hole one, which is located below the dustproof plate. A path groove is provided on one side of the cylinder body near the impellers. The two mounting plates are respectively provided with deployment components for controlling the impellers (143). The deployment components include a connecting plate, a support arm one, a support arm two, and a rotating disk. The inner side of the short plate of the mounting plate is fixedly installed with the connecting plate, and the end face of the connecting plate is hinged to the support arm one and the support arm two respectively. The rotating disk is sleeved on the rotating shaft and is located on the side of the mounting plate away from the wire control wheel. The end face of the rotating disk away from the mounting plate has two arc-shaped grooves, which are symmetrical about the center of the rotating shaft. A sliding rod is provided at the end of the support arm one and the support arm two away from the connecting plate. One end of the sliding rod is connected to the adjacent arc-shaped groove. A sliding connection is used; one side of support arm one is hinged to support rod one, and one side of support arm two is hinged to support rod two. Support rod one and support rod two are of the same length. The ends of support rod one and support rod two away from the rotating shaft pass through the path groove on the same side and are hinged to the adjacent impeller. Therefore, the rotating shaft drives the rotating disk, and the arc-shaped groove controls the expansion or contraction of support arm one and support arm two through the sliding rod. In turn, support rod one and support rod two pull the corresponding impeller to expand or contract. According to field coordination analysis, when the angle between the impeller and the cylinder body is approximately - degrees, the material velocity direction is roughly in the same direction as the axis. At this time, the flow resistance between the material around the cylinder body and the material that is not in contact with the cylinder body is small, and the airflow velocity is fast. When the angle between the impeller and the cylinder body is approximately - degrees, the material velocity direction deviates significantly from the axis. At this time, the flow resistance between the material around the cylinder body and the material that is not in contact with the cylinder body increases, and the airflow velocity decreases. Thus, without reducing the gas flow rate per unit area, the airflow velocity can be adjusted in real time to cope with the need to adjust for deviations in material fineness.

[0018] Furthermore, the hinge point of the first strut is higher than the hinge point of the second strut, and the second strut is located on the side of the cylinder away from the lower ring frame; thus, the two impellers are not deployed to the same degree, with the impeller corresponding to the second strut deployed to a lesser degree than the impeller corresponding to the first strut; thereby reducing the interference of the impeller near the center on the material discharged from the output pipe.

[0019] Furthermore, the pulverizing mechanism includes a separating cylinder and a processing cylinder. The separating cylinder is located below the processing cylinder. One side of the separating cylinder and the processing cylinder are connected by a conveying pipe. The other side of the separating cylinder is provided with an air inlet pipe. The port of the air inlet pipe is connected to a fan through a pipeline. The end of the separating cylinder near the grinding mechanism is provided with an output port. The inner wall of the processing cylinder is provided with convex balls, and a crushing roller is installed inside the processing cylinder via bearings. The outer side of the crushing roller is provided with protrusions, and a rotary motor is fixedly connected to one end of the crushing roller. The outer side of the rotary motor is fixedly connected to the processing cylinder. The side of the processing cylinder away from the separation cylinder is provided with a feeding end. Thus, the low-temperature dried peony flowers enter the processing cylinder from the feeding end. Since the petals are more brittle than the calyx under the same degree of dryness, the rotary motor drives the crushing roller to rotate. The protrusions on the crushing roller drive the flowers to rotate and, together with the convex balls, crush the flowers. The crushing intensity is less than the intensity that destroys the shape of the calyx. The petals on the calyx are crushed and crushed, thereby achieving the separation of the petals from the calyx. A support is fixedly installed inside the separation cylinder. A baffle is mounted on the inner wall of the support via bearings. A discharge pipe is mounted on the end of the separation cylinder away from the grinding mechanism via bearings. A wire cage is provided between the baffle and the discharge pipe. The maximum end face of the wire cage and the end face of the separation cylinder are clearance-fitted. A gear is provided on the side of the discharge pipe outside the separation cylinder. A drive mechanism is meshed on the side of the gear. Thus, petal fragments and flower buds enter the separation cylinder through the conveying pipe. The drive mechanism drives the discharge pipe to rotate via the gear, thereby causing the wire cage to lift the material. A fan provides airflow to the separation cylinder. The petal fragments enter the grinding mechanism under airflow, while the flower buds enter the wire cage under the action of gravity and pressure, and are then discharged from the discharge pipe, thus achieving the separation of petal fragments and flower buds.

[0020] Furthermore, the screening and recovery mechanism includes a housing, a fixed frame, and a screen disk. The fixed frame is fixed inside the housing, and the screen disk is located on one side of the fixed frame and is fixedly connected to the housing. A connecting shaft is provided in the center of the side of the fixed frame near the screen disk. The end of the connecting shaft away from the fixed frame passes through the screen disk, and a sleeve is installed at the end via a bearing. A spiral guide plate is fixedly installed on the side of the sleeve, and one side of the spiral guide plate is slidably connected to the screen disk. A fan blade is circumferentially arranged on the side of the sleeve, and the fan blade is located on the side of the spiral guide plate away from the screen disk. Thus, the rising airflow drives the sleeve to rotate through the fan blade, causing the spiral guide plate to rotate, thereby distributing the unevenly distributed powder at the screen disk, allowing the powder to pass through the screen disk quickly, and preventing the unevenly distributed powder from accumulating at the screen disk due to excessive flow velocity, indirectly avoiding clogging at the screen disk.

[0021] Furthermore, a recycling port is provided on one side of the housing, and the outer end of the recycling port is connected to the end cap through a one-way pipe; thus, after the refined unqualified powder reaches the screen disk, the rotating spiral guide plate moves it to the edge of the screen disk, and as it moves, it re-enters the grinding mechanism from the recycling port for secondary grinding; thereby achieving the effect of real-time recycling of refined unqualified powder.

[0022] Furthermore, the method of using the above-mentioned medicinal peony petal pulverizing and grinding device is as follows: S1. The flowers that have been dried at low temperature are poured into the processing cylinder of the crushing mechanism to crush the flowers, thereby obtaining petal fragments and flower receptacles; S2. Subsequently, the petal fragments and flower receptacles enter the separation cylinder, and the petal fragments are conveyed by the wind into the grinding mechanism; the wire cage inside the separation cylinder collects and discharges the flower receptacles. S3. Petal fragments are conveyed into the equalizing chamber by wind power, where they are carried by the supersonic airflow along the tangential direction at high speed, causing them to collide and pulverize with each other; the refined particles converge towards the center and enter the screening and recycling mechanism through the output pipe. S4. Determine whether the particle refinement intensity needs to be adjusted by judging the content of the material after passing through the screening and recovery mechanism per unit time; if the content is lower than the standard range, it means that the amount of particles returned from the screening and recovery mechanism is too large, and the refinement intensity of the grinding mechanism needs to be adjusted. S5. When it is necessary to increase the refining force of the grinding mechanism, the control component manipulates multiple control components to move synchronously, so that the included angle between multiple grinding cylinders and the fixed plate increases synchronously; the dustproof plate end face is pulled to present multiple arc ribs; so that in addition to colliding with each other, the petal fragments also impact the grinding cylinders and arc ribs, increasing the probability of the petal fragments being crushed, and indirectly increasing the refining force. Simultaneously, after rotation, the impellers on both sides of the grinding cylinder are pushed open by the unfolding mechanism inside the cylinder. This slows down the airflow velocity around the cylinder on a microscopic level, making the centrifugal force of the petal fragments greater than the inertial force, thus turning the material around the cylinder from a near-laminar flow to a local turbulent flow, thereby increasing the crushing force. However, on a macroscopic level, it does not affect the overall airflow velocity, and therefore does not affect the overall powder conveying force.

[0023] The beneficial effects of this application are as follows: The medicinal peony petal pulverizing and grinding device provided by this application is equipped with a grinding cylinder, multiple control components, and a regulating component. The regulating component controls the synchronous operation of multiple control components, and then controls the synchronous movement of the corresponding grinding cylinder through the control component. The grinding cylinder can rotate on the wear-resistant bed under the control of the control component. The change of the angle between the grinding cylinder and the wear-resistant bed is proportional to the degree of directional interference to the flowing material. The greater the degree of interference, the more collisions between materials, and thus the finer the material, thereby realizing real-time control of powder coarseness.

Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1-21 As shown (where the arrows indicate the material flow), this application provides a pulverizing and grinding device for medicinal peony petals, used in the processing of medicinal peony petals, including a grinding mechanism 1, a pulverizing mechanism 2, and a screening and recovery mechanism 3; see reference. Figure 1 The output end of the crushing mechanism 2 is connected to the grinding mechanism 1 through a pipeline. The screening and recycling mechanism 3 is located above the grinding mechanism 1, and the output end of the grinding mechanism 1 is connected to the screening and recycling mechanism 3 through a pipeline. The crushing mechanism 2 separates the petals from the calyx and crushes the petals. Then, the petals are transported to the grinding mechanism 1 by wind power for powder refinement. After passing through the screening and recycling mechanism 3, the powder is collected. The screening and recycling mechanism 3 can screen out unqualified powder and return it to the grinding mechanism 1 for secondary processing.

[0029] Reference Figure 2 , Figure 3 , Figure 4 The grinding mechanism 1 includes a wear-resistant bed 13, multiple grinding cylinders 14, multiple control components 15, and a regulating component 16. The bottoms of the multiple grinding cylinders 14 are hinged to the wear-resistant bed 13, and the multiple grinding cylinders 14 are arranged circumferentially on the wear-resistant bed 13. The control components 15 and regulating component 16 are located below the wear-resistant bed 13. The multiple control components 15 are arranged circumferentially with the regulating component 16 as the center, and the support ends of the regulating component 16 are connected to the control components 15 through ball joints. Each control component 15 corresponds to one grinding cylinder 14 and is connected to it by a control rope. The regulating component 16 controls the multiple control components 15 to operate synchronously, and then controls the corresponding grinding cylinders 14 to move synchronously through the control components 15. Under the control of the control components 15, the grinding cylinders 14 can rotate on the wear-resistant bed 13. The change in the angle between the grinding cylinders 14 and the wear-resistant bed 13 is proportional to the degree of directional interference to the flowing material. The greater the degree of interference, the more collisions occur between the materials, and thus the finer the material is, thereby achieving real-time control of the powder coarseness.

[0030] Reference Figure 4 , Figure 8 , Figure 9The grinding cylinder 14 includes a cylinder body 141 and a take-up device 145. Rope holes 1411 are respectively opened on both sides of the cylinder body 141. The take-up device 145 is located inside the cylinder body 141. The cylinder body 141 is equipped with a mounting frame, which suspends the take-up device 145. Control ropes are fixedly connected to both ends of the take-up device 145. The other end of the control rope passes through an adjacent rope hole 1411 and is fixedly connected to the wear-resistant machine 13. The side of the take-up device 145 is wound around the middle section of the control rope. The mounting frame includes two mounting plates 1441 and a mounting bracket 1442. The mounting plates 1441 are L-shaped plates, and the two mounting plates 1441 are connected to each other. The components are arranged back to back and connected by a connecting frame 1443. One of the mounting plates 1441 is fixedly connected to the mounting frame 1442 on the side away from the connecting frame 1443, and the end of the mounting frame 1442 away from the corresponding mounting plate 1441 is fixedly connected to the cylinder body 141. The side of the take-up and release device 145 is connected to the mounting plate 1441 by a bearing. Thus, the corresponding control component 15 controls the rotation of the take-up and release device 145 through a control rope. The rotating take-up and release device 145 winds one control rope and releases the other control rope. The rotation of the cylinder body 141 is controlled by the tension difference between the two control ropes.

[0031] The control rope is made of high-performance polyethylene material, and the adjustment rope is formed by winding steel wire; thus, the control rope has high deformation force and is resistant to low temperature and wear. The control rope drives the take-up and release device 145 to rotate through elastic deformation and friction force; the adjustment rope is not easily deformed and has high toughness.

[0032] Reference Figure 9 , Figure 10 The retractor 145 includes a rotating shaft 1451, a control wheel 1452, and two cable locking buttons 1453. The control wheel 1452 is fixedly installed in the middle of the rotating shaft 1451, and the two cable locking buttons 1453 are fixedly installed on the side of the rotating shaft 1451, with the control wheel 1452 located between the two cable locking buttons 1453. The rotating shaft 1451 passes through two mounting plates 1441 and is connected by bearings. The control wheel 1452 is located between the two mounting plates 1441, and the two mounting plates 1441 are located between the two cable locking buttons 1453. The side of the control wheel 1452 is connected to the control wheel 1453. The middle section of the rope is wound and connected, and the end faces of the two wire locking keys 1453 are respectively fixedly connected to the control rope. The other end of the control rope passes through the rope hole 1411 and is fixedly connected to the wear-resistant machine 13. Thus, the control component 15 pulls back the two ends of the control rope, causing the control wheel 1452 in the middle section of the control rope to rotate, and then the rotating shaft 1451 rotates synchronously. One control rope is wound on the rotating shaft 1451, and the other control rope gradually unwinds from the rotating shaft 1451, so that the length of the control rope at the winding point gradually shortens, pulling the cylinder 141 to rotate in the tightening direction.

[0033] Reference Figure 4The wear-resistant bed 13 consists of a fixed plate 131 and a dustproof plate 132. The fixed plate 131 is located below the dustproof plate 132, and the dustproof plate 132 is made of polyethylene material; see reference. Figure 5 , Figure 6 The top of the fixed plate 131 has multiple pairs of movable slots 1311 and multiple pairs of rope holes 1312. Each pair of rope holes 1312 corresponds to a pair of movable slots 1311, and the pair of rope holes 1312 is located between the pairs of movable slots 1311. The movable slots 1311 and rope holes 1312 are arranged circumferentially. The cylinder 141 is located on top of the fixed plate 131. A pair of hinge frames 142 are provided at the bottom of the cylinder 141. Each hinge frame 142 corresponds to a movable slot 1311, and the hinge frame 142 is installed inside the movable slot 1311. Both ends of the control rope pass through the corresponding rope holes 1312 to reach the control component 15. One end of the adjustment rope outside the cylinder 141 is fixedly connected to the fixed plate 131. One adjustment rope is located at one end of the corresponding movable slot 1311, and the other adjustment rope is located at the other end of the corresponding movable slot 1311. (Refer to...) Figure 4 The end of the cylinder 141 away from the fixed plate 131 passes through the dustproof plate 132, and the side of the cylinder 141 is fixedly connected to the dustproof plate 132. The axis of the cylinder 141 is tangent to and opposite to the material's direction. After the material enters the equalization chamber 11, it is spirally moved on the dustproof plate 132 and then exits through the output pipe 122. When the angle between the cylinder 141 and the fixed plate 131 is at its minimum, the plane of the dustproof plate 132 is in a stretched state. When the angle between the cylinder 141 and the fixed plate 131 increases, the cylinder 141 pulls the dustproof plate 132, causing it to deform, and the end face of the dustproof plate 132 exhibits multiple arc ribs (see reference). Figure 7 This causes more material to impact the dustproof plate 132 for crushing and grinding.

[0034] Reference Figure 2 , Figure 3The grinding mechanism 1 also includes a pressure equalization chamber 11 and an end cap 12. The pressure equalization chamber 11 is provided with a heat insulation layer. The end cap 12 is located above the pressure equalization chamber 11 and is connected by a transition fit.

[0035] Reference Figure 14 , Figure 15 The control component 15 includes a base 151 and a control rod 153. The bottom of the base 151 is fixedly connected to the equalizing chamber 11. Two wire seats 152 are installed on one side of the top of the base 151. The control rod 153 is located between the two wire seats 152. One end of the control rod 153 is hinged to the center of the top of the base 151. The end of the control rod 153 away from the base 151 is connected to the control component 16 through a ball joint. Wire buckles 154 are fixedly installed on both sides of the control rod 153. The end of the control rope passes through the corresponding wire seat 152 and is fixedly connected to the wire buckle 154 on the same side. Thus, the control component 16 controls the control rod 153 to swing, and the wire buckle 154 drives the end of the control rope to move, so that the control rope achieves a pulling and rotating effect on the retractor 145.

[0036] Reference Figure 15 , Figure 16The control component 16 includes a base 161, a servo motor 165, and a control panel 166. The bottom of the base 161 is fixedly connected to the equalizing chamber 11. The servo motor 165 is fixedly installed in the center of the base 161. The output end of the servo motor 165 away from the base 161 is fixedly connected to the control panel 166. Multiple sliding grooves 1661 are circumferentially arranged on the end face of the control panel 166. Multiple slide rails 1621 are fixedly installed on the top of the base 161. The slide rails 1621 are circumferentially arranged. A sliding seat 1622 is slidably connected to the top of each slide rail 1621. A pull rod is fixedly installed on the top of the sliding seat 1622 away from the base 161. The control lever 163 and the sliding key 164 are located between the control panel 166 and the base 161. The sliding key 164 corresponds one-to-one with the slide groove 1661, and the end of the sliding key 164 away from the base 161 and the corresponding slide groove 1661 are mating mechanisms. The end of the pulling rod 163 away from the sliding seat 1622 is connected to the corresponding control lever 153 through a ball joint. Thus, the servo motor 165 causes the control panel 166 to rotate, and the slide groove 1661 controls the sliding seat 1622 to slide on the slide rail 1621 through the sliding key 164, so that the pulling rod 163 drives the control lever 153 to swing.

[0037] Reference Figure 8 Two impellers 143 are hinged to the outer side of the cylinder body 141 above the dustproof plate 132. The two impellers 143 are arranged symmetrically and are not on the same side as the rope hole 1411. The rope hole 1411 is located below the dustproof plate 132. A path groove 1412 is opened on one side of the cylinder body 141 located on the impeller 143. Reference Figure 9 , Figure 11 , Figure 12 , Figure 13The two mounting plates 1441 are respectively provided with deployment assemblies for controlling the impeller 143. The deployment assembly includes a connecting plate 1461, a first support arm 1462, a second support arm 1463, and a rotating disk 1464. The inner side of the short plate of the mounting plate 1441 is fixedly installed to the connecting plate 1461, and the end face of the connecting plate 1461 is hinged to the first support arm 1462 and the second support arm 1463 respectively. The rotating disk 1464 is sleeved on the rotating shaft 1451 and is located on the mounting plate 1441 away from the line. On one side of the control wheel 1452, two arc-shaped grooves 14641 are formed on the end face of the rotating disk 1464 away from the mounting plate 1441. The two arc-shaped grooves 14641 are symmetrical about the center of the rotating shaft 1451. A sliding rod is provided at the end of the support arm 1462 and the support arm 2 1463 away from the connecting plate 1461, and one end of the sliding rod is slidably connected to the adjacent arc-shaped groove 14641. A support rod 14621 is hinged to one side of the support arm 1462, and a support rod 2 14631 is hinged to one side of the support arm 2 1463. Support arm 14621 and support rod 14631 are of the same length. The ends of support arms 14621 and 14631 away from the rotating shaft 1451 pass through the path groove 1412 on the same side and are hinged to the adjacent impeller 143. Therefore, the rotating shaft 1451 drives the rotating disk 1464, and the arc groove 14641 controls the extension or retraction of support arms 1462 and 1463 through a sliding rod. In turn, support arms 14621 and 14631 pull the corresponding impeller 143 to extend or retract. According to the field coordination... Analysis shows that when the angle between the impeller 143 and the cylinder 141 is approximately 10-20 degrees, the material velocity direction is roughly in the same direction as the axis. At this time, the flow resistance between the material on the side of the cylinder 141 and the non-contact material around the cylinder 141 is small, and the airflow velocity is high. When the angle between the impeller 143 and the cylinder 141 is approximately 20-30 degrees, the material velocity direction deviates significantly from the axis. At this time, the flow resistance between the material on the side of the cylinder 141 and the non-contact material around the cylinder 141 increases, and the airflow velocity decreases. Therefore, without reducing the gas flow rate per unit area, the airflow velocity can be adjusted in real time to address situations where adjustments are needed to address deviations in material refinement.

[0038] Reference Figure 12 The hinge point of strut 14621 is higher than the hinge point of strut 214631, and strut 214631 is located on the side of cylinder 141 away from the lower ring frame 112. As a result, the two impellers 143 are not deployed to the same degree, and the impeller 143 corresponding to strut 214631 is deployed to a lesser degree than the impeller 143 corresponding to strut 11621. This reduces the interference of the impeller 143 near the center with the material being discharged from the output pipe 122.

[0039] Reference Figure 17 , Figure 18The crushing mechanism 2 includes a separation cylinder 21 and a processing cylinder 22. Both the separation cylinder 21 and the processing cylinder 22 are made of heat-insulating material. The separation cylinder 21 is located below the processing cylinder 22. The separation cylinder 21 and the processing cylinder 22 are connected on one side by a conveying pipe 23. An air inlet pipe 25 is provided on the other side of the separation cylinder 21. A fan is connected to the port of the air inlet pipe 25 through a pipeline. An output port is provided at the end of the separation cylinder 21 near the grinding mechanism 1. Reference Figure 18 The inner wall of the processing cylinder 22 is provided with convex balls 221. A crushing roller 222 is installed inside the processing cylinder 22 via bearings. The outer side of the crushing roller 222 is provided with protrusions. One end of the crushing roller 222 is fixedly connected to a rotary motor 24, and the outer side of the rotary motor 24 is fixedly connected to the processing cylinder 22. The side of the processing cylinder 22 away from the separation cylinder 21 is provided with a feeding end. Thus, the low-temperature dried peony flowers enter the processing cylinder 22 from the feeding end. Since the petals are more brittle than the calyx under the same degree of drying, the rotary motor 24 drives the crushing roller 222 to rotate. The protrusions on the crushing roller 222 drive the flowers to rotate and, together with the convex balls 221, crush the flowers. The crushing intensity is less than the intensity that destroys the shape of the calyx. The petals on the calyx are crushed and crushed, thereby achieving the separation of the petals from the calyx. Reference Figure 18 , Figure 19 A bracket 211 is fixedly installed inside the separating cylinder 21. A baffle 2121 is installed on the inner wall of the bracket 211 via bearings. An outlet pipe 2122 is installed on the end of the separating cylinder 21 away from the grinding mechanism 1 via bearings. A wire cage 2123 is provided between the baffle 2121 and the outlet pipe 2122. The maximum end face of the wire cage 2123 is clearance-fitted with the end face of the separating cylinder 21. A gear 214 is provided on the side of the outlet pipe 2122 outside the separating cylinder 21. A drive motor is meshed on the side of the gear 214. The structure is as follows: petal fragments and flower receptacles enter the separation cylinder 21 through the conveying pipe 23. The drive mechanism drives the outlet pipe 2122 to rotate through the gear 214, thereby driving the wire cage 2123 to lift the material. The fan provides airflow to the separation cylinder 21, and the gas introduced is a low-temperature inert gas. The petal fragments enter the grinding mechanism 1 under the airflow, and the flower receptacles enter the wire cage 2123 under the action of gravity and pressure, and are then discharged from the outlet pipe 2122, thereby realizing the separation of petal fragments and flower receptacles.

[0040] Reference Figure 20 , Figure 21The screening and recycling mechanism 3 includes a housing 31, a fixing frame 32, and a screen disk 33. The housing 31 is made of heat-insulating material. The fixing frame 32 is fixed inside the housing 31. The screen disk 33 is located on one side of the fixing frame 32 and is fixedly connected to the housing 31. A connecting shaft is provided in the center of the side of the fixing frame 32 near the screen disk 33. The end of the connecting shaft away from the fixing frame 32 passes through the screen disk 33, and a sleeve 341 is installed at the end through a bearing. A spiral guide plate 342 is fixedly installed on the side of the sleeve 341. One side of the spiral guide plate 342 is slidably connected to the screen disk 33, and the sleeve 341 is circumferentially provided with a fan blade on its side. The fan blade is located on the side of the spiral guide plate 342 away from the screen disk 33. Thus, the rising airflow drives the sleeve 341 to rotate through the fan blade, causing the spiral guide plate 342 to rotate. This distributes the unevenly distributed powder at the screen disk 33, allowing the powder to pass through the screen disk 33 quickly. This prevents the unevenly distributed powder from accumulating at the screen disk 33 due to excessive flow rate, indirectly preventing blockage at the screen disk 33.

[0041] Reference Figure 21 A recycling port 311 is provided on one side of the housing 31. The outer end of the recycling port 311 is connected to the end cover 12 through a one-way pipe. Thus, after the finely refined unqualified powder reaches the screen disk 33, the rotating spiral guide plate 342 moves it to the edge of the screen disk 33. As it moves, it re-enters the grinding mechanism 1 from the recycling port 311 for secondary grinding. This achieves the effect of real-time recycling of finely refined unqualified powder.

[0042] The operating steps of the above-mentioned medicinal peony petal pulverizing and grinding device are as follows: S1. The flowers that have been dried at low temperature are poured into the processing cylinder 22 of the crushing mechanism 2 to crush the flowers, thereby obtaining petal fragments and flower receptacles; S2. Subsequently, the petal fragments and flower receptacles enter the separation cylinder 21. The petal fragments are conveyed by the wind into the grinding mechanism 1. The wire cage 2123 inside the separation cylinder 21 collects and discharges the flower receptacles. S3. Petal fragments are conveyed into the equalizing chamber 11 by wind power and carried by the supersonic airflow inside, moving at high speed along the tangential direction, causing them to collide and crush with each other; the refined particles converge towards the center and enter the screening and recycling mechanism 3 through the output pipe 122. S4. Determine whether the particle refining intensity needs to be adjusted by judging the content of the material after passing through the screening and recovery mechanism 3 per unit time; when the content is lower than the standard range, it means that the amount of particles returned from the screening and recovery mechanism 3 is too large, and the refining intensity of the grinding mechanism 1 needs to be adjusted. S5. When it is necessary to increase the refining force of the grinding mechanism 1, the control component 16 controls multiple control components 15 to move synchronously, so that the included angle between multiple grinding cylinders 14 and the fixed plate 131 increases synchronously; the end face of the dustproof plate 132 is pulled to present multiple arc ribs; so that in addition to colliding with each other, the petal fragments also impact the grinding cylinders 14 and the arc ribs, increasing the probability of the petal fragments being crushed, and indirectly increasing the refining force. Simultaneously, after rotation, the impellers 143 on both sides of the grinding cylinder 14 are pushed and unfolded by the unfolding mechanism inside the cylinder body 141; microscopically, this slows down the airflow velocity around the cylinder body 141, making the centrifugal force of the petal fragments greater than the inertial force, thereby changing the material around the cylinder body 141 from a near-laminar flow to a local turbulent flow, thus increasing the crushing force, but macroscopically it does not affect the overall airflow velocity, and therefore does not affect the overall powder conveying force.
