Abstract
Description
Technical Field
[0001] This application relates to the field of crushing equipment, and in particular to a crushing device and a method for crushing raw materials for kidney-tonifying and yang-boosting products using the device. Background Technology
[0002] In the preparation of traditional Chinese medicine, the medicinal materials need to be crushed to facilitate subsequent processing.
[0003] Existing Chinese herbal medicine crushing devices include a housing and two crushing rollers. The two crushing rollers rotate in opposite directions. The Chinese herbal medicine is fed between the two crushing rollers, and the crushing rollers crush it.
[0004] However, during the crushing process, friction between the crushing roller and the medicinal material generates heat, causing the surface temperature of the crushing roller to rise. Under high temperature conditions, the medicinal properties of the medicinal material are easily reduced, affecting the subsequent processing of the medicinal material. Summary of the Invention
[0005] To improve the cooling effect and preserve the medicinal properties, this application provides a crushing device and a method for crushing raw materials of kidney-tonifying and yang-strengthening products using the device.
[0006] The crushing device provided in this application adopts the following technical solution:
[0007] A crushing device includes a shell, two crushing rollers, a drive mechanism, a first water inlet pipe, a first water outlet pipe, a second water inlet pipe, and a second water outlet pipe. The shell has a feed inlet and a discharge outlet at its upper and lower ends, respectively. Each crushing roller includes a roller body and multiple protruding teeth on its surface. Tubular rotating shafts are fixedly installed at both ends of the roller body and are rotatably connected to the shell. The drive mechanism drives the rotating shafts to rotate. The roller body has a cylindrical structure. A first partition cylinder is coaxially fixed inside the roller body. A first flow channel is formed between the outer circumferential surface of the first partition cylinder and the inner circumferential surface of the roller body. The first water inlet pipe and the first water outlet pipe are respectively connected to both ends of the first flow channel, and the water flow directions of the first flow channels of the two crushing rollers are opposite. A second partition cylinder is coaxially fixed inside the roller body. A second flow channel is formed between the outer circumferential surface of the second partition cylinder and the inner circumferential surface of the first partition cylinder. Each protruding tooth has a cooling chamber. The second flow channel is sequentially connected to the cooling chambers of each protruding tooth in the axial arrangement direction. The second water inlet pipe and the second water outlet pipe are respectively connected to both ends of the second flow channel, and the water flow directions of the second flow channels of the two crushing rollers are opposite.
[0008] By adopting the above technical solution, cooling water can be used to cool the roller body through the first inlet pipe and the second outlet pipe, while cooling water can be used to cool each tooth through the second inlet pipe and the second outlet pipe, thereby improving the cooling effect and maintaining the medicinal properties.
[0009] Furthermore, the water flow directions in the second channels of the two crushing rollers are opposite to balance the heat dissipation effect of the two crushing rollers and avoid the occurrence of poor local heat dissipation.
[0010] Furthermore, since the teeth and rollers are cooled separately, the water flow rate and volume can be adjusted according to the crushing conditions. As the main heat-generating location, the teeth can utilize high-speed cooling water to accelerate heat dissipation, while the rollers generate less heat, so the cooling water flow rate can be reduced, thereby reducing cooling water waste.
[0011] Optionally, both ports of the two rotating shafts are coaxially connected to rotary joints, which are externally fixed. The first inlet pipe and the first outlet pipe are eccentrically fixed to the rotary joints. The second inlet pipe and the second outlet pipe are coaxially inserted and fixed to the two rotary joints respectively. The diameters of the second inlet pipe and the second outlet pipe are both smaller than the inner diameter of the rotating shaft. The port of the rotating shaft away from the rotary joint is integrally formed with a first conical sleeve. The first conical sleeve is fixed to the roller body by a first bolt. The end of the first partition cylinder is fixed with a second conical sleeve by a second bolt. A conical gap is formed between the second conical sleeve and the first conical sleeve. The small ports of the two second conical sleeves are respectively attached to the outer circumferential surfaces of the second inlet pipe and the second outlet pipe. Multiple partition rings are coaxially fixed to the outer circumferential surface of the first partition cylinder. Each partition ring is arranged at intervals along the axial direction of the first partition cylinder. The partition rings have first through holes. The first through holes of adjacent partition rings are staggered. The outer circumferential surface of the partition rings is attached to the inner circumferential surface of the roller body. An annular flow cavity is provided between adjacent partition rings. The combination of each annular flow cavity forms the first flow channel.
[0012] By adopting the above technical solution, the water from the first inlet pipe enters the first outlet pipe through the annular gap between the rotating shaft and the second inlet pipe, the conical gap between the second conical sleeve and the first conical sleeve, and the first flow channel composed of various annular flow cavities, thereby cooling the roller body.
[0013] By setting up multiple partition rings, the water movement time and path in the first flow channel are extended, thereby improving the cooling effect.
[0014] Optionally, both ends of the second partition cylinder are fixed with conical heads by third bolts. Multiple first partition strips are fixed to the outer circumferential surface of the conical heads, with each first partition strip evenly arranged circumferentially. The first partition strips divide the gap between the conical head and the second conical sleeve into multiple evenly arranged first strip-shaped cavities. Multiple axially extending second partition strips are fixed to the outer circumferential surface of the second partition cylinder, with each second partition strip evenly arranged circumferentially. The second partition strips divide the second flow channel into multiple evenly arranged second strip-shaped cavities, with each second strip-shaped cavity corresponding to and communicating with one of the first strip-shaped cavities. The ports of the second inlet pipe and the second outlet pipe abut against the outer conical surface of the conical head. Both the inlet pipe and the second outlet pipe have through notches connecting to the first strip cavity; one end of the protruding tooth is a crushing end, the opening of the cooling cavity is located at the end of the protruding tooth away from the crushing end, the opening of the cooling cavity is located inside the second strip cavity, the second partition cylinder has a connecting seat, the connecting seat is fixed with a partition plate, the partition plate is inserted into the cooling cavity, and the partition plate blocks the second strip cavity; one end of the partition plate has a second through hole, the partition plate divides the cooling cavity into U-shaped cavities, the inlet and outlet of the U-shaped cavity of each protruding tooth in the axial arrangement direction are connected to the same second strip cavity; the surface of the partition plate is vertically fixed to the rib plate, and the rib plate abuts against the inner wall of the cooling cavity.
[0015] By adopting the above technical solution, the cooling water in the second inlet pipe passes through the notch, the first strip cavity, the second strip cavity, and each U-shaped cavity (by turning through the second through hole) in sequence, and enters the second outlet pipe, thereby cooling the protruding teeth.
[0016] Furthermore, by setting up a baffle, the baffle can block the second strip cavity and the cooling cavity, so that the cooling water in the second strip cavity can only enter the next section of the second strip cavity through the U-shaped cavity. This allows the cooling water to cool each tooth in the axial direction in sequence, and the cooling water flows through the cooling cavity, which greatly improves the cooling effect on the tooth.
[0017] Secondly, by setting ribs that abut against the inner wall of the cooling chamber, the thin-walled protruding teeth are structurally reinforced, thereby reducing the occurrence of deformation of the protruding teeth under pressure.
[0018] Optionally, multiple through-holes are provided, with each through-hole corresponding to one of the first strip cavities.
[0019] Optionally, the outer circumferential surfaces of the second inlet pipe and the second outlet pipe are composed of a blocking area and an opening area. The notch is located in the opening area, and the central angle of the arc length of the opening area is 120°. The end of the first strip cavity is connected to the second inlet pipe or the second outlet pipe through the opening area, and the end of the first strip cavity is blocked by the blocking area. When the convex tooth rotates in the direction close to the other crushing roller, the first strip cavity corresponding to the convex tooth cooperates with the opening area.
[0020] By adopting the above technical solution, the cooling water in the second inlet pipe can only enter the defined first strip cavity through the through-gap in the opening area, while the ends of the remaining first strip cavities are blocked by the blocking area, that is, there is no flow or no cooling water in the remaining first strip cavities.
[0021] By setting up an open zone and a closed zone, the cooling water in the second inlet pipe can only flow into the cooling chamber of the defined protrusions. These defined protrusions are either about to enter the crushing state or are in the crushing state, thus providing targeted cooling and reducing the occurrence of low cooling efficiency caused by general cooling.
[0022] Optionally, both the partition plate and the rib plate are inserted into the tooth. The roller body has a first through hole through which the tooth passes radially along the roller body. The first partition cylinder has a second through hole through which the tooth passes radially along the roller body. The second partition cylinder has a third through hole through which the connecting seat passes radially along the roller body. A first anti-detachment ring is fixed to the middle of the outer surface of the tooth. A second anti-detachment ring is fixed to the end of the tooth away from the crushing end. An anti-detachment block is fixed to the connecting seat. Rubber pads are provided on the surfaces of the first anti-detachment ring, the second anti-detachment ring, and the anti-detachment block. The rubber pad of the first anti-detachment ring is attached to the inner circumferential surface of the roller body. The rubber pad of the second anti-detachment ring is attached to the inner circumferential surface of the first partition cylinder. The rubber pad of the anti-detachment block is attached to the inner circumferential surface of the second partition cylinder. A reinforcing component is provided inside the second partition cylinder. The reinforcing component is used to fix and force the connecting seat to move radially outward along the roller body.
[0023] By adopting the above technical solution, when installing the first and second partition cylinders, the partition ring and the protruding tooth are pre-positioned on the first partition cylinder to ensure that the crushing end of the protruding tooth slides and retracts into the gap between the two partition rings. Then, the first partition cylinder is axially inserted into the roller body. At this time, the outer circumferential surface of the partition ring is in contact with the inner circumferential surface of the roller body. When the protruding tooth is near the first through hole, the protruding tooth is radially slid outward so that the crushing end of the protruding tooth passes through the first through hole. At this time, the rubber pad of the first anti-detachment ring is in contact with the inner circumferential surface of the roller body, and the rubber pad of the second anti-detachment ring is in contact with the inner circumferential surface of the first partition cylinder.
[0024] Then, the second partition cylinder with the second partition strip fixed is axially inserted into the first partition cylinder, and the connecting seat with the partition plate and rib plate is radially outwardly passed through the third through hole so that the partition plate is inserted into the cooling cavity of the protruding tooth. Then, the connecting seat and the second partition cylinder are fixed by the reinforcing component to position and fix the partition plate and the protruding tooth.
[0025] Finally, install the conical head, the second conical sleeve, and the first conical sleeve in sequence.
[0026] Optionally, the reinforcement assembly includes a first circular plate, a second circular plate, a fastening screw, a nut, and a disc spring. Both the first and second circular plates have clearance notches on their outer edges. One end of the fastening screw is fixed to the center of the first circular plate, and the other end of the fastening screw passes through the second circular plate. The nut is threadedly connected to the fastening screw and abuts against the surface of the second circular plate via the disc spring. Both the first and second circular plates have first guide surfaces on their outer edges, and the anti-detachment block has a second guide surface that mates with the first guide surface.
[0027] By adopting the above technical solution, the spring force of the disc spring moves the broken second circular plate toward the first circular plate by tightening the nut. With the cooperation of the first guide surface and the second guide surface, the spring force of the disc spring is transformed into a force that forces the partition to move outward. The partition is more tightly inserted into the convex tooth, thereby applying internal stress to the convex tooth to improve the structural strength of the convex tooth.
[0028] Optionally, both the partition plate and the rib plate are fixedly connected to the protruding tooth; the roller body is provided with a first through hole through which the protruding tooth slides radially along the roller body, the first partition cylinder is provided with a second through hole through which the protruding tooth slides radially along the roller body, and the second partition cylinder is provided with a third through hole through which the connecting seat slides radially along the roller body; the first through hole, the second through hole, and the third through hole are all provided with sealing rings; the connecting seat is fixed with a guide block, and the second partition cylinder is provided with a reinforcing component, which includes a first circular plate, a second circular plate, a fastening screw, a nut, and a tension spring; the outer edges of the first circular plate and the second circular plate are provided with clearance notches; one end of the fastening screw is fixed to the center of the first circular plate, and the other end of the fastening screw passes through the second circular plate; the nut is threadedly connected to the fastening screw and abuts against the surface of the second circular plate; the outer edges of the first circular plate and the second circular plate are provided with a first guide surface, and the guide block is provided with a second guide surface that mates with the first guide surface; both ends of the tension spring are fixedly connected to the guide block and the fastening screw, respectively.
[0029] By adopting the above technical solution, by setting the first through hole, the second through hole and the third through hole, the protrusion can be radially damped and slid. The cooperation of the first guide surface and the second guide surface limits one of the extreme positions of the protrusion to avoid the protrusion sliding too far radially inward. The tension spring is set to ensure the subsequent movement and reset of the protrusion.
[0030] By adjusting the water pressure guided by the U-shaped cavity and the centrifugal force of the crushing roller, for example, increasing the water pressure and increasing the rotational speed of the crushing roller, this force will force the convex teeth to move radially outward, while decreasing the water pressure and decreasing the rotational speed of the crushing roller will cause the convex teeth to slide radially inward under the action of the tension spring.
[0031] By adjusting the water pressure guided by the U-shaped cavity and the centrifugal force of the crushing roller, the radial extension distance of the convex teeth can be controlled, making the gap between the convex teeth of the two crushing rollers adjustable, thereby realizing the dynamic adjustment of the crushing mesh size to be suitable for crushing medicinal materials of different sizes and shapes.
[0032] This application also provides a method for crushing raw materials of kidney-tonifying and yang-boosting products using a crushing device, employing the following technical solution:
[0033] A method for crushing raw materials for a kidney-tonifying and yang-enhancing product using a crushing device includes the following steps: The raw materials for the kidney-tonifying and yang-enhancing product are fed into the housing through the feed inlet; the drive mechanism drives two crushing rollers to rotate in opposite directions; the protruding teeth on the two crushing rollers engage to crush the raw materials; the crushed raw materials pass sequentially through the gap between the two crushing rollers and are discharged from the outlet; during this process, cooling water is introduced into the first flow channel through the first water inlet pipe to cool the rollers; cooling water is also introduced into the second flow channel through the second water inlet pipe to cool the protruding teeth through the cooling chamber; the flow velocity in the second flow channel is greater than the flow velocity in the first flow channel.
[0034] Optionally, the raw materials for the kidney-tonifying and yang-strengthening product include Cynomorium songaricum, Eucommia ulmoides, cinnamon, processed Aconitum carmichaelii, ginseng, Poria cocos, Atractylodes macrocephala, and licorice.
[0035] In summary, this application includes at least one of the following beneficial technical effects:
[0036] 1. Through the first water inlet pipe and the second water outlet pipe, cooling water can pass through the first flow channel to cool the roller body, while through the second water inlet pipe and the second water outlet pipe, cooling water can pass through the second flow channel and the cooling chamber to cool each tooth, so as to improve the cooling effect, improve the cooling uniformity and maintain the medicinal properties.
[0037] 2. By setting up an open area and a closed area, the cooling water in the second water inlet pipe can only flow in the cooling chamber of the defined protrusion, which is about to enter the crushing state or is in the crushing state, so as to cool in a targeted manner and reduce the occurrence of low cooling efficiency caused by general cooling.
[0038] 3. By utilizing the water pressure and centrifugal force guided by the U-shaped cavity, the radial extension distance of the convex teeth is controlled, making the gap between the convex teeth between the two crushing rollers adjustable, thereby realizing the dynamic adjustment of the crushing mesh size to suit the crushing of medicinal materials of different sizes and shapes.

Detailed Implementation
[0052] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.
[0053] Example 1
[0054] Example 1 discloses a crushing device. For example... Figure 1 , Figure 2 As shown, the crushing device includes a housing 10, two crushing rollers 20, a drive mechanism (not shown in the figure), a first water inlet pipe 31, a first water outlet pipe 32, a second water inlet pipe 51, and a second water outlet pipe 52. The upper and lower ends of the housing 10 are respectively provided with a feed inlet 101 and a discharge outlet 102. The two crushing rollers 20 are arranged horizontally side by side, and there is a gap between the two crushing rollers 20. The crushing roller 20 includes a roller body 1 and a plurality of protruding teeth 2 provided on the surface of the roller body 1. The two ends of the roller body 1 are coaxially fixedly mounted with tubular rotating shafts 11. The rotating shafts 11 pass through the housing 10 and are rotatably connected to the housing 10. The drive mechanism can be a motor. The drive mechanism drives the rotating shafts 11 to rotate through a gear 12, so that the two crushing rollers 20 rotate in opposite directions to achieve crushing processing.
[0055] like Figure 2 , Figure 3 As shown, the roller body 1 has a cylindrical structure, and a first conical sleeve 13 is integrally formed at one end of the two rotating shafts 11. The first conical sleeve 13 is coaxially arranged with the rotating shaft 11, and the two first conical sleeves 13 are coaxially fixed to the two ends of the roller body 1 by first bolts 15.
[0056] A rotary joint 30 is coaxially connected to the end of the rotating shaft 11 away from the first conical sleeve 13, meaning that each of the two rotating shafts 11 is provided with a rotary joint 30. The rotary joint 30 is externally fixed, allowing the rotating shaft 11 to rotate relative to the rotary joint 30. The first water inlet pipe 31 and the first water outlet pipe 32 are eccentrically fixed to the two rotary joints 30, respectively. The second water inlet pipe 51 and the second water outlet pipe 52 are coaxially fixed to the two rotary joints 30, respectively. The diameters of the second water inlet pipe 51 and the second water outlet pipe 52 are both smaller than the inner diameter of the rotating shaft 11, meaning there is a gap between the outer circumferential surface of the second water inlet pipe 51 and the inner circumferential surface of the rotating shaft 11, through which the cooling water of the first water inlet pipe 31 can pass.
[0057] like Figure 3 , Figure 4 As shown, a first partition cylinder 6 is coaxially fixed inside the roller body 1. A second conical sleeve 61 is fixed to the end of the first partition cylinder 6 by a second bolt 62. The second conical sleeve 61 is coaxially arranged with the first partition cylinder 6. A conical gap is formed between the second conical sleeve 61 and the first conical sleeve 13. The small ports of the two second conical sleeves 61 are respectively attached to the outer circumferential surface of the second water inlet pipe 51 and the second water outlet pipe 52 (to prevent water in the first water inlet pipe 31 from mixing into the second water inlet pipe 51).
[0058] A first flow channel is formed between the outer peripheral surface of the first partition cylinder 6 and the inner peripheral surface of the roller body 1. Specifically, multiple partition rings 63 are coaxially fixed on the outer peripheral surface of the first partition cylinder 6. Each partition ring 63 is arranged at intervals along the axial direction of the first partition cylinder 6. Each partition ring 63 has a first through hole 64. The first through holes 64 of adjacent partition rings 63 are staggered. The outer peripheral surface of the partition ring 63 is in contact with the inner peripheral surface of the roller body 1. An annular flow cavity is provided between adjacent partition rings 63. Each annular flow cavity is combined to form the first flow channel, and the water flow direction of the first flow channel of the two crushing rollers 20 is opposite.
[0059] Water from the first inlet pipe 31 passes sequentially through the annular gap between the rotating shaft 11 and the second inlet pipe 51, the conical gap between the second conical sleeve 61 and the first conical sleeve 13, the first flow channel composed of various annular flow cavities, the conical gap between the second conical sleeve 61 and the first conical sleeve 13, and the annular gap between the rotating shaft 11 and the second outlet pipe 52, and enters the first outlet pipe 32, thereby cooling the roller body 1.
[0060] By setting multiple partition rings 63, the water movement time and path in the first flow channel are extended, thereby improving the cooling effect.
[0061] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a second partition cylinder 7 is coaxially fixed inside the roller body 1. The diameter of the second partition cylinder is smaller than that of the first partition cylinder. A second flow channel is formed between the outer circumferential surface of the second partition cylinder 7 and the inner circumferential surface of the first partition cylinder 6.
[0062] Both ends of the second partition cylinder 7 are fixed with conical heads 71 by the third bolt 72. The ends of the second water inlet pipe 51 and the second water outlet pipe 52 respectively abut against the outer conical surfaces of the two conical heads 71, that is, the conical heads 71 block the second water inlet pipe 51 and the second water outlet pipe 52.
[0063] A conical gap is formed between the outer conical surface of the conical head 71 and the second conical sleeve 61. A plurality of first spacers 73 are fixed on the outer circumferential surface of the conical head 71. The first spacers 73 extend along the generatrix of the outer conical surface of the conical head 71. Each first spacer 73 is evenly arranged circumferentially. The first spacers 73 divide the conical gap formed between the conical head 71 and the second conical sleeve 61 into a plurality of first strip cavities evenly arranged circumferentially. The ports of the second water inlet pipe 51 and the second water outlet pipe 52 are provided with a plurality of through notches 511. Each through notch 511 is corresponding to each first strip cavity, that is, the cooling water in the second water inlet pipe 51 can enter the first strip cavity through the through notch 511.
[0064] Multiple axially extending second partition bars 74 are fixed on the outer circumferential surface of the second partition cylinder 7. The second partition bars 74 are evenly arranged circumferentially, dividing the second flow channel into multiple evenly arranged second strip cavities 70. Each second strip cavity 70 forms a second flow channel, and the second strip cavity 70 is connected to the first strip cavity in a one-to-one correspondence. The water flow directions of the second flow channels of the two crushing rollers 20 are opposite.
[0065] The protruding tooth 2 is a long strip structure. One end of the protruding tooth 2 is set as the crushing end 211, and the other end of the protruding tooth 2 is provided with a strip-shaped cooling cavity 21. That is, the opening of the cooling cavity 21 is located at the end of the protruding tooth 2 away from the crushing end 211.
[0066] The roller body 1 is provided with a first through hole 14 through which the protruding tooth 2 passes radially along the roller body 1, and the first partition cylinder 6 is provided with a second through hole 65 through which the protruding tooth 2 passes radially along the roller body 1. That is, the protruding tooth 2 and the roller body 1 can be installed through the through hole connection. Furthermore, a first anti-detachment ring 22 is fixed in the middle of the outer surface of the protruding tooth 2, and a second anti-detachment ring 23 is fixed in the end of the protruding tooth 2 away from the crushing end 211. Both the first anti-detachment ring 22 and the second anti-detachment ring 23 are provided with rubber pads 27. The rubber pads 27 of the first anti-detachment ring 22 are attached to the inner circumferential surface of the roller body 1, and the rubber pads 27 of the second anti-detachment ring 23 are attached to the inner circumferential surface of the first partition cylinder 6 to reduce the overflow of cooling water.
[0067] The opening of the cooling cavity 21 is connected to the second strip cavity 70.
[0068] like Figure 6 , Figure 7 As shown, the second partition cylinder 7 is provided with a connecting seat 24. Specifically, the second partition cylinder 7 is provided with a third through hole 75 through which the connecting seat 24 passes radially along the roller body 1. The connecting seat 24 is fixed with an anti-detachment block 25. The surface of the anti-detachment block 25 is provided with a rubber pad 27. The rubber pad 27 of the anti-detachment block 25 is attached to the inner circumferential surface of the second partition cylinder 7. The anti-detachment block 25 is fixedly connected to the second partition cylinder 7 by a fourth bolt 26.
[0069] The connecting seat 24 is fixed with a partition 251, which is inserted into the cooling cavity 21 and blocks the second strip cavity 70. One end of the partition 251 is provided with a second through hole 252. The partition 251 divides the cooling cavity 21 into a U-shaped cavity. The inlet and outlet of the U-shaped cavity of each tooth 2 in the axial arrangement direction are connected to the same second strip cavity 70. That is, the cooling water in the second strip cavity 70 can only enter the next section of the second strip cavity 70 through the U-shaped cavity, so that the cooling water can cool each tooth 2 in the axial direction in sequence. Moreover, the cooling water flows through the cooling cavity 21, which greatly improves the cooling effect on the tooth 2.
[0070] In summary, the cooling water from the second inlet pipe 51 passes through the notch 511, the first strip cavity, the second strip cavity 70, each U-shaped cavity (which bends through the second through hole 252), the first strip cavity, and then through the notch 511 to enter the second outlet pipe 52, thereby cooling the protruding tooth 2.
[0071] Furthermore, the surface of the partition plate 251 is vertically fixed to the rib plate 253, and the rib plate 253 abuts against the inner wall of the cooling cavity 21 to structurally reinforce the thin-walled protrusion 2, thereby reducing the occurrence of deformation of the protrusion 2 under pressure.
[0072] In this way, by setting up the first flow channel and the second flow channel to cool the roller body 1 and the convex tooth 2 respectively, the water flow rate and water flow can be adjusted according to the crushing situation. As the main heat-generating position, the convex tooth 2 can use high-speed cooling water to accelerate the heat dissipation of the convex tooth 2, while the roller body 1 generates less heat, so the cooling water flow rate can be reduced, thereby reducing the waste of cooling water.
[0073] Meanwhile, the above structure is also easy to install. Specifically, the spacer ring 63 and the tooth 2 are pre-installed on the first spacer cylinder 6 to ensure that the crushing end 211 of the tooth 2 slides into the gap between the two spacer rings 63. Then, the first spacer cylinder 6 is axially inserted into the roller body 1. At this time, the outer circumferential surface of the spacer ring 63 is in contact with the inner circumferential surface of the roller body 1. When the tooth 2 is near the first through hole 14, the tooth 2 is radially slid outward so that the crushing end 211 of the tooth 2 passes through the first through hole 14. At this time, the rubber pad 27 of the first anti-detachment ring 22 is in contact with the inner circumferential surface of the roller body 1, and the rubber pad 27 of the second anti-detachment ring 23 is in contact with the inner circumferential surface of the first spacer cylinder 6.
[0074] Then, the second partition cylinder 7, which is fixed with the second partition bar 74, is axially inserted into the first partition cylinder 6. The connecting seat 24 with the partition plate 251 and the rib plate 253 is radially outwardly passed through the third through hole 75, so that the partition plate 251 is inserted into the cooling cavity 21 of the protrusion 2. Then, the connecting seat 24 and the second partition cylinder 7 are fixed by the fourth bolt 26, thereby positioning and fixing the partition plate 251 and the protrusion 2.
[0075] Finally, install the conical head 71, the second conical sleeve 61, and the first conical sleeve 13 in sequence.
[0076] Example 1 also discloses a method for crushing raw materials of kidney-tonifying and yang-supporting products using the above-mentioned crushing device, including the following steps: feeding the raw materials of kidney-tonifying and yang-supporting products into the shell 10 through the feed inlet 101. The raw materials of kidney-tonifying and yang-supporting products include Cynomorium songaricum, Eucommia ulmoides, Cinnamomum cassia, processed Aconitum carmichaelii, Ginseng, Poria cocos, Atractylodes macrocephala, and Glycyrrhiza uralensis.
[0077] The drive mechanism drives two crushing rollers 20 to rotate in opposite directions. The protruding teeth 2 on the two crushing rollers 20 cooperate to crush the raw materials of the kidney-tonifying and yang-strengthening product. The crushed raw materials of the kidney-tonifying and yang-strengthening product pass through the gap between the two crushing rollers 20 and are discharged from the discharge port 102.
[0078] During this period, cooling water is introduced into the first flow channel through the first water inlet pipe 31 to cool the roller body 1. Cooling water is introduced into the second flow channel through the second water inlet pipe 51 to cool the convex tooth 2 through the cooling chamber 21. Furthermore, the flow velocity in the second flow channel is greater than that in the first flow channel.
[0079] Example 2
[0080] The difference between Example 2 and Example 1 is that, as Figure 9 As shown, there is only one gap 511. Specifically, the outer periphery of the second water inlet pipe 51 and the second water outlet pipe 52 is composed of a blocking area 512 and an opening area 513. The gap 511 is the opening area 513, and the central angle of the arc length of the opening area 513 is 120°.
[0081] The ends of some of the first strip cavities are connected to the second inlet pipe 51 or the second outlet pipe 52 through the opening area 513, while the ends of the remaining first strip cavities are blocked by the blocking area 512.
[0082] That is, the cooling water in the second inlet pipe 51 can only enter the defined first strip cavity through the through-hole 511 in the opening area 513, while the ends of the remaining first strip cavities are blocked by the blocking area 512, meaning that there is no flow or no cooling water in the remaining first strip cavities.
[0083] The first strip cavity defined above is specifically as follows: Figure 8The first strip cavity within the arc length range defined by the dotted line will connect with the opening area 513. Furthermore, when the protruding tooth 2 rotates in the direction close to the other crushing roller 20, the first strip cavity corresponding to the protruding tooth 2 will cooperate with the opening area 513.
[0084] Therefore, the cooling water in the second water inlet pipe 51 can only flow into the cooling chamber 21 of the defined protrusion 2, which is about to enter the crushing state or is in the crushing state, so as to cool in a targeted manner and reduce the occurrence of low cooling efficiency caused by general cooling.
[0085] Example 3
[0086] The difference between Example 3 and Example 1 is that, as Figure 9 , Figure 10 As shown, a reinforcing assembly is provided inside the second partition cylinder 7. The reinforcing assembly is used to fix and force the connecting seat 24 to move radially outward along the roller body 1. Specifically, the reinforcing assembly includes a first circular plate 81, a second circular plate 82, a fastening screw 83, a nut 84, and a disc spring 85. One end of the fastening screw 83 is fixed to the center of the first circular plate 81, and the other end of the fastening screw 83 passes through the second circular plate 82. The nut 84 is threadedly connected to the fastening screw 83, and the nut 84 abuts against the surface of the second circular plate 82 through the disc spring 85.
[0087] Both the first circular plate 81 and the second circular plate 82 have clearance notches 812 on their outer edges. The clearance notches 812 are used to avoid the connecting seat 24, so as to facilitate the installation of the first circular plate 81 and the second circular plate 82.
[0088] The outer edges of the first circular plate 81 and the second circular plate 82 are provided with a first guide surface 811, and the anti-detachment block 25 is provided with a second guide surface 254 that cooperates with the first guide surface 811. That is, after the first circular plate 81 and the second circular plate 82 are installed, the first circular plate 81 and the second circular plate 82 are rotated so that the first guide surface 811 on them cooperates with the second guide surface 254. Then, by tightening the nut 84, the elastic force of the disc spring 85 moves the broken second circular plate 82 toward the first circular plate 81. With the cooperation of the first guide surface 811 and the second guide surface 254, the elastic force of the disc spring 85 is converted into a force that forces the partition 251 to move outward. The partition 251 is more tightly inserted into the protrusion 2, thereby applying internal stress to the protrusion 2 to improve the structural strength of the protrusion 2.
[0089] Example 4
[0090] The difference between Example 4 and Example 1 is that, as Figure 11 , Figure 12As shown, the first anti-detachment ring 22, the second anti-detachment ring 23 and the anti-detachment block 25 are removed, so that the protrusion 2 slides and engages with the first through hole 14 and the second through hole 65 respectively, and the connecting seat 24 slides and engages with the third through hole 75. The first through hole 14, the second through hole 65 and the third through hole 75 are all provided with sealing rings 28, so that the sliding engagement has damping.
[0091] Furthermore, both the partition plate 251 and the rib plate 253 are fixedly connected to the tooth 2. This fixing method can be an interference fit or adhesive fixing; the connecting seat 24 is fixed with a guide block 29.
[0092] This embodiment also includes a reinforcement assembly, which includes a first circular plate 81, a second circular plate 82, a fastening screw 83, a nut 84, and a tension spring 86. One end of the fastening screw 83 is fixed to the center of the first circular plate 81, and the other end of the fastening screw 83 passes through the second circular plate 82. The nut 84 is threadedly connected to the fastening screw 83 and abuts against the surface of the second circular plate 82.
[0093] Both the first circular plate 81 and the second circular plate 82 have clearance notches 812 (not shown in the figure) on their outer edges. Both the first circular plate 81 and the second circular plate 82 have first guide surfaces 811 on their outer edges. The guide block 29 has a second guide surface 254 that cooperates with the first guide surface 811. The two ends of the tension spring 86 are fixedly connected to the guide block 29 and the fastening screw 83 by hooking. The tension spring 86 is provided to ensure the subsequent movement and reset of the protruding tooth 2.
[0094] When the water pressure increases and the rotational speed of the crushing roller 20 increases, the cooling water turns at the second through hole 252. The water pressure of the cooling water is applied to the tooth 2, which forces the tooth 2 and the connecting seat 24 to move radially outward. The centrifugal force of rotation will also force the tooth 2 and the connecting seat 24 to move radially outward. That is, the combined force of water pressure and centrifugal force will force the tooth 2 to move radially outward.
[0095] When the water pressure decreases and the rotation speed of the crushing roller 20 decreases, the tooth 2 slides radially inward under the force of the tension spring 86.
[0096] That is, by adjusting the water pressure guided by the U-shaped cavity and the centrifugal force of the crushing roller 20, the radial extension distance of the convex tooth 2 is controlled, so that the gap between the convex teeth 2 between the two crushing rollers 20 is adjustable, thereby realizing the dynamic adjustment of the crushing mesh size, so as to be suitable for crushing medicinal materials of different sizes and shapes.
[0097] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
