[0003] The existing crushing device for traditional Chinese medicine comprises a shell and two crushing rollers, the two crushing rollers rotate towards each other, the traditional Chinese medicine is put between the two crushing rollers, and the crushing rollers crush it.

[0004] However, during the crushing process, the friction between the crushing roller and the medicinal materials generates heat, causing the surface temperature of the crushing roller to rise. Under high temperature conditions, the medicinal properties of the medicinal materials can be easily reduced, affecting the subsequent processing of the medicinal materials. Summary of the invention

[0005] In order to improve the cooling effect and maintain the medicinal properties, the present application provides a crushing device and a method for crushing the raw materials of a kidney-tonifying and yang-boosting product using the device.

[0006] The present application provides a crushing device, which adopts the following technical solution:

[0010] In addition, since the cam and the roller body are cooled separately, the water flow rate and water flow rate can be adjusted according to the crushing conditions. The cam, as the main heat generating location, can use high-speed cooling water to accelerate the heat dissipation of the cam, while the roller body generates less heat, so the cooling water flow rate can be lowered, thereby reducing cooling water waste.

[0015] By adopting the above technical solution, the cooling water in the second water inlet pipe passes through the gap, the first strip cavity, the second strip cavity, and each U-shaped cavity (turned through the second through hole) in sequence, and enters the second water outlet pipe, thereby cooling the convex teeth.

[0016] In addition, by setting a partition, the partition can block the second strip cavity and the cooling cavity, so that the cooling water in the second strip cavity can only pass through the U-shaped cavity to enter the next section of the second strip cavity, so that the cooling water can cool each convex tooth in the axial direction in turn, and the cooling water flows through the cooling cavity, greatly improving the cooling effect on the convex teeth.

[0017] Secondly, by providing ribs that abut against the inner wall of the cooling cavity, the thin-walled convex teeth are structurally reinforced, thereby reducing the occurrence of compression deformation of the convex teeth.

[0018] Optionally, the number of the through-notches is multiple, and each of the through-notches is arranged in one-to-one correspondence with each of the first strip-shaped cavities.

[0020] By adopting the above technical solution, the cooling water in the second water inlet pipe can only enter the limited first strip-shaped cavity through the notch in the open area, and the ends of the remaining first strip-shaped cavities are blocked by the blocking area, that is, there is no flow of cooling water or no cooling water in the remaining first strip-shaped cavities.

[0021] By setting the opening area and the blocking area, the cooling water of the second water inlet pipe can only flow in the cooling cavity of the limited convex teeth, and the limited convex teeth are in the state of about to enter the crushing state or in the crushing state, so as to carry out targeted cooling to reduce the occurrence of low cooling efficiency caused by comprehensive cooling.

[0022] Optionally, the partition plate and the rib plate are both plug-fitted with the convex tooth, the roller body is penetrated by a first through-hole for the convex tooth to pass through radially along the roller body, the first spacer is penetrated by a second through-hole for the convex tooth to pass through radially along the roller body, and the second spacer is penetrated by a third through-hole for the connecting seat to pass through radially along the roller body; a first anti-slip ring is fixed to the middle part of the outer surface of the convex tooth, a second anti-slip ring is fixed to the end of the convex tooth away from the crushing end, and a anti-slip block is fixed to the connecting seat, and the surfaces of the first anti-slip ring, the second anti-slip ring and the anti-slip block are all provided with rubber pads, the rubber pad of the first anti-slip ring is fitted to the inner circumferential surface of the roller body, the rubber pad of the second anti-slip ring is fitted to the inner circumferential surface of the first spacer, and the rubber pad of the anti-slip block is fitted to the inner circumferential surface of the second spacer; a reinforcement component is provided in the second spacer, and the reinforcement 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 spacer and the second spacer, the spacer ring and the convex tooth are pre-positioned on the first spacer to ensure that the crushing end of the convex tooth slides and retracts into the gap between the two spacer rings, and then the first spacer is axially inserted into the roller body. At this time, the outer circumferential surface of the spacer ring fits the inner circumferential surface of the roller body. When the convex tooth is located near the first through-hole, the convex tooth is radially slid outward so that the crushing end of the convex tooth passes through the first through-hole. At this time, the rubber pad of the first anti-slip ring fits the inner circumferential surface of the roller body, and the rubber pad of the second anti-slip ring fits the inner circumferential surface of the first spacer.

[0024] Then, the second spacer with the second spacer strip fixed thereon is axially inserted into the first spacer, and the connecting seat with the partition and the ribs is radially passed outward through the third through-hole so that the partition is inserted into the cooling cavity of the convex tooth. Then, a reinforcement assembly is used to fix the connecting seat and the second spacer to position and fix the partition and the convex tooth.

[0027] By adopting the above technical solution, the elastic force of the disc spring will move the broken second circular plate toward the first circular plate through the tightening of the nut. By utilizing the cooperation of the first guide surface and the second guide surface, the elastic force of the disc spring is converted 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, the partition and the rib are both fixedly connected to the convex tooth; the roller body is penetrated by a first through-hole for the convex tooth to slide through along the radial direction of the roller body, the first partition cylinder is penetrated by a second through-hole for the convex tooth to slide through along the radial direction of the roller body, and the second partition cylinder is penetrated by a third through-hole for the connecting seat to slide through along the radial direction of 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 a reinforcement component is provided in the second partition cylinder, and the reinforcement component includes a first circular plate, a second circular plate, a fastening screw, a nut and a tension spring, and the outer edges of the first circular plate and the second circular plate are both provided with avoidance 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, and the nut is threadedly connected to the fastening screw, and the nut abuts against the surface of the second circular plate; the outer edges of the first circular plate and the second circular plate are both provided with a first guide surface, and the guide block is provided with a second guide surface matching the first guide surface; the two ends of the tension spring are respectively fixedly connected to the guide block and the fastening screw.

[0029] By adopting the above technical solution, by setting the first perforation, the second perforation and the third perforation, the convex tooth can perform radial damping sliding, and the first guide surface and the second guide surface cooperate to limit one of the extreme positions of the convex tooth to avoid the convex tooth from sliding radially inward too far, and the setting of the tension spring is used to ensure the subsequent movement and reset of the convex tooth.

[0030] By adjusting the water pressure guided by the U-shaped cavity and the centrifugal force of the crushing roller, for example, when the water pressure increases and the rotation speed of the crushing roller increases, the force will force the convex teeth to move radially outward, while when the water pressure decreases and the rotation speed of the crushing roller decreases, the convex teeth will slide radially inward under the action of the tension spring.

[0031] The radial expansion and contraction distance of the convex teeth is controlled by adjusting the water pressure guided by the U-shaped cavity and the rotating centrifugal force of the crushing roller, so that the convex tooth gap between the two crushing rollers can be adjusted, thereby realizing dynamic adjustment of the crushing mesh number to be suitable for the crushing of medicinal materials of different sizes and shapes.

[0032] The present application also provides a method for crushing raw materials of kidney-tonifying and yang-boosting products using a crushing device, which adopts the following technical solution:

[0072] In this way, by setting the first flow channel and the second flow channel to cool the roller body 1 and the convex teeth 2 respectively, the water flow rate and the water flow rate can be adjusted according to the crushing situation. The convex teeth 2 are the main heat generating position, and high-speed cooling water can be used to accelerate the heat dissipation of the convex teeth 2. The roller body 1 generates less heat, so the cooling water flow rate can be lowered to reduce the waste of cooling water.

[0073] At the same time, the above structure is also easy to install. Specifically, the spacer ring 63 and the convex tooth 2 are pre-installed on the first spacer cylinder 6 to ensure that the broken end 211 of the convex tooth 2 slides and retracts into the gap between the two spacer rings 63, and then the first spacer cylinder 6 is axially inserted into the roller body 1. At this time, the outer circumference of the spacer ring 63 fits the inner circumference of the roller body 1. When the convex tooth 2 is located near the first through-hole 14, the convex tooth 2 is radially slid outward so that the broken end 211 of the convex tooth 2 passes through the first through-hole 14. At this time, the rubber pad 27 of the first anti-slip ring 22 fits the inner circumference of the roller body 1, and the rubber pad 27 of the second anti-slip ring 23 fits the inner circumference of the first spacer cylinder 6.

[0074] Then, the second partition tube 7 fixed with the second partition bar 74 is axially inserted into the first partition tube 6, and the connecting seat 24 with the partition 251 and the rib 253 is radially passed outward through the third through-hole 75 so that the partition 251 is inserted into the cooling cavity 21 of the protruding tooth 2, and then the fourth bolt 26 is used to fix the connecting seat 24 and the second partition tube 7, so as to position and fix the partition 251 and the protruding tooth 2.

[0075] Finally, the conical head 71, the second conical sleeve 61 and the first conical sleeve 13 are installed in sequence.

[0076] Example 1 also discloses a method for crushing the raw materials of kidney-tonifying and yang-boosting products using the above-mentioned crushing device, comprising the following steps: feeding the raw materials of kidney-tonifying and yang-boosting products into the shell 10 through the feed port 101, and the raw materials of kidney-tonifying and yang-boosting products include Cynomorium songaricum, Eucommia ulmoides, cinnamon bark, processed aconite, ginseng, Poria cocos, Atractylodes macrocephala, and licorice.

[0077] The driving mechanism drives the two crushing rollers 20 to rotate towards each other, and the convex teeth 2 on the two crushing rollers 20 cooperate with each other to crush the raw materials of the kidney-tonifying and yang-boosting product. The crushed raw materials of the kidney-tonifying and yang-boosting product pass through the gap between the two crushing rollers 20 in turn 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, and the cooling water cools the roller body 1. Cooling water is introduced into the second flow channel through the second water inlet pipe 51, and the cooling water flows through the cooling cavity 21 of the convex tooth 2 to cool the convex tooth 2; and the flow rate in the second flow channel is greater than the flow rate in the first flow channel.

[0079] Example 2

[0080] The difference between Example 2 and Example 1 is that Fig. 9 As shown, there is only one gap 511. Specifically, the outer peripheral surface of the second water inlet pipe 51 and the second water outlet pipe 52 is composed of a blocking area 512 and an open area 513. The gap 511 is the open area 513, and the central angle of the arc length of the open area 513 is 120°.

[0081] The ends of some of the first strip-shaped cavities are connected to the second water inlet pipe 51 or the second water outlet pipe 52 through the opening area 513 , and the ends of the other first strip-shaped cavities are blocked by the blocking area 512 .

[0082] That is, the cooling water in the second water inlet pipe 51 can only enter the limited first strip-shaped cavity through the through-notch 511 in the opening area 513, and the ends of the other first strip-shaped cavities are blocked by the blocking area 512, that is, the cooling water in the other first strip-shaped cavities has no flow or no cooling water.

[0083] The first strip-shaped cavity defined above is specifically Figure 8The first strip-shaped cavity within the arc length range circled by the dotted line will be connected to the opening area 513 . Furthermore, when the convex tooth 2 rotates in a direction close to the other crushing roller 20 , the first strip-shaped cavity corresponding to the convex tooth 2 cooperates with the opening area 513 .

[0084] Therefore, the cooling water of the second water inlet pipe 51 can only flow in the cooling cavity 21 of the limited convex tooth 2, and the limited convex tooth 2 is about to enter the crushing state or is in the crushing state, so as to perform targeted cooling to reduce the occurrence of low cooling efficiency caused by comprehensive cooling.

[0085] Example 3

[0086] The difference between Example 3 and Example 1 is that Fig. 9 , Fig.10 As shown, a reinforcement component is provided in the second spacer 7, and the reinforcement component is used to fix and force the connecting seat 24 to move radially outward along the roller body 1. Specifically, the reinforcement component 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] The first circular plate 81 and the second circular plate 82 are both provided with an avoidance notch 812 at their outer edges. The avoidance notch 812 is used to avoid the connecting seat 24 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 both provided with a first guide surface 811, and the anti-slip block 25 is provided with a second guide surface 254 that matches 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 thereon matches with the second guide surface 254, and then by tightening the nut 84, the elastic force of the disc spring 85 will break the second circular plate 82 and move it toward the first circular plate 81. By utilizing the cooperation between 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, and the partition 251 is more tightly inserted into the convex tooth 2, thereby applying internal stress to the convex tooth 2 to improve the structural strength of the convex tooth 2.

[0089] Example 4

[0090] The difference between Example 4 and Example 1 is that Fig.11 , Fig.12As shown, the first anti-slip ring 22, the second anti-slip ring 23 and the anti-slip block 25 are eliminated, so that the protruding tooth 2 is slidingly matched with the first through hole 14 and the second through hole 65 respectively, and the connecting seat 24 is slidingly matched with the third through hole 75, and 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 fit has damping.

[0091] Furthermore, the partition plate 251 and the rib plate 253 are both fixedly connected to the protruding teeth 2 , and the fixing method may be interference fit or adhesive fixation; the connecting seat 24 is fixed with a guide block 29 .

[0092] The present 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 the nut 84 abuts against the surface of the second circular plate 82.

[0093] The outer edges of the first circular plate 81 and the second circular plate 82 are both provided with avoidance notches 812 (not shown in the figure), the outer edges of the first circular plate 81 and the second circular plate 82 are both provided with first guide surfaces 811, and the guide block 29 is provided with a second guide surface 254 that matches the first guide surface 811; the two ends of the tension spring 86 are respectively fixedly connected to the guide block 29 and the fastening screw 83 by hooking, and the setting of the tension spring 86 is used to ensure the subsequent movement and reset of the convex tooth 2.

[0094] When the water pressure increases and the rotation speed of the crushing roller 20 increases, when the cooling water turns at the second through hole 252, the water pressure of the cooling water is applied to the convex tooth 2 to force the convex tooth 2 and the connecting seat 24 to move radially outward, and the rotational centrifugal force will also force the convex tooth 2 and the connecting seat 24 to move radially outward, that is, the combined force of the water pressure and the centrifugal force will force the convex tooth 2 to move radially outward.

[0095] When the water pressure decreases and the rotation speed of the crushing roller 20 decreases, the protruding teeth 2 slide radially inwards under the force of the tension spring 86 .

[0096] That is, the radial expansion and contraction distance of the convex teeth 2 is controlled by adjusting the water pressure guided by the U-shaped cavity and the rotating centrifugal force of the crushing roller 20, so that the gap between the convex teeth 2 of the two crushing rollers 20 is adjustable, thereby realizing the dynamic adjustment of the crushing mesh number to be suitable for the crushing of medicinal materials of different sizes and shapes.

[0097] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
