Description

Technical Field

[0001] The invention relates to the technical field of important processing devices, in particular to a traditional Chinese medicine grinding device. Background Art

[0002] Traditional Chinese medicine, or TCM medicine, is a unique medicine of traditional Chinese medicine. Traditional Chinese medicine consists of plant medicine, animal medicine and mineral medicine, and plant medicine, animal medicine and mineral medicine are mostly large blocks or irregular shapes. If they are directly added to the casserole for decoction, the effective ingredients in the medicine cannot be fully released into the decoction, and the effect after the patient takes it is not ideal. Therefore, it is necessary to grind the traditional Chinese medicine into fine powder. Most of the existing traditional Chinese medicine grinding is manual grinding. Long-term manual grinding will soon make people feel tired, and the grinding speed is slow and time-consuming. When there are too many medicinal materials, it requires more manpower. Therefore, in order to improve the grinding efficiency and save manpower, an automated traditional Chinese medicine grinding device came into being.

[0003] CN112427066B discloses a grinding device, and more particularly relates to a Chinese medicine grinding device. The purpose of the present invention is to provide a Chinese medicine grinding device that can automatically discharge materials into a stone trough for automatic grinding. In order to solve the above technical problems, a Chinese medicine grinding device is provided, which includes a base, a support swing seat, a support plate, a motor, a large gear and a vertical bracket, etc. The base is fixedly connected with a support swing seat, wherein the support swing seat is located on one side close to the vertical bracket, the support plate is located on the other side close to the vertical bracket, the motor is installed on the support plate, the large gear is installed on the output shaft of the motor, and a lower grinding mechanism is provided on the base, which is connected to the large gear. When the stone mill reciprocates in the grinding stone pot, when the grinding stone pot is located at the top, the stone mill contacts the grinding stone pot, so that the Chinese medicine in the grinding stone pot is fully ground. When the grinding stone pot moves upward, the stone mill contacts the Chinese medicine more closely, which plays the role of fully grinding.

[0004] However, in the process of Chinese medicine processing, Chinese medicine particles of different sizes can be used for different usage requirements, such as preparing different preparations (such as powders, pills, granules, etc.). Traditional Chinese medicine grinders can often only grind a single particle size, or adjust the particle size by replacing screens of different coarseness and fineness, which increases the complexity of operation and time cost. Therefore, there is an urgent need for a grinding device that can process two Chinese medicine raw materials of different particle sizes at the same time. Summary of the invention

When the running frame is running, the protrusions collide back and forth with the groove wall of the fixed groove. Since the automatic lifting elastic grinding plate has an elastic extrusion effect on the grinding net, it will not have a fixing effect on the grinding net. When the protrusions collide with the groove wall of the fixed groove, a certain vibration force will be formed on the grinding net, and then a vibration force will be generated on the medicine particles blocked in the mesh of the grinding net. While not affecting the grinding, the medicine particles blocked in the mesh of the grinding net are separated from the mesh and enter the medicine collection box to prevent the mesh from being blocked. The arrangement of multiple protrusions and multiple groove walls of the fixed groove can further improve the vibration effect and further prevent the mesh from being blocked.

The rubbing and grinding net 11 cooperates with the automatic lifting elastic rubbing and grinding plate, the mesh diameter of the rubbing and grinding net 11 is smaller than the mesh diameter of the grinding net 9, and a receiving chamber 12 for receiving the medicinal materials in the medicine receiving chamber 10 and a conveying chamber 13 for conveying the medicinal materials in the medicine receiving chamber 10 to the rubbing and grinding net 11 are provided at the bottom of the medicine receiving chamber 10, the receiving chamber 12 and the conveying chamber 13 are threadedly connected to the bottom of the medicine receiving chamber 10, and an opening and closing device for opening and closing the cavity openings of the receiving chamber 12 and the conveying chamber 13 is provided on the medicine receiving chamber 10. According to different needs, the raw materials after rough grinding are received or conveyed by the opening and closing device. A control valve is provided in the conveying chamber, and the control valve is an electromagnetic valve. A driving mechanism for driving the grinding roller 8 and the elastic rubbing and grinding plate to operate is provided on the bearing frame, and a controller is also included. The controller is a PLC. The grinder can grind two Chinese medicine raw materials with different particle sizes at the same time, does not need to replace the screen, is simple to operate, has a high degree of automation, and effectively reduces time costs.

[0028] The automatic lifting elastic grinding plate includes a fixed cavity 14 arranged at the bottom of the sliding frame, and a driving cylinder 15 arranged in the fixed cavity 14, a running plate 16 slidably connected to the inner wall of the fixed cavity 14 is arranged at the bottom of the driving cylinder 15, a driving spring 17 is arranged at the bottom of the running plate 16, a rod 18 is arranged at the bottom of the driving spring 17, and a grinding plate body 19 is arranged at the bottom of the rod 18, and the driving cylinder 15 is connected to the controller signal. By setting the driving spring, the grinding plate body and the medicinal material raw material are kept pre-tightened in real time, and the medicinal material raw material is ground step by step, and the grinding fineness is improved by combining the shear force of the mesh of the grinding net. In addition, the elastic grinding method is adopted to avoid the phenomenon of the raw materials being pressed together due to the unidirectional force.

[0029] The driving mechanism includes a fixed plate 20 arranged on the carrying frame, a driving motor 21 is provided on one side of the fixed plate 20, and a first rotating rod 22 is provided on the driving motor 21, a second rotating rod 23 is provided on the first rotating rod 22 and is rotatably connected to the first rotating rod 22, a driving rod 24 is provided at one end of the second rotating rod 23 and is rotatably connected to the second rotating rod 23, a first U-shaped driving frame 25 for driving the sliding frame to operate is provided at one end of the driving rod 24, a limiting cavity 38 for keeping the driving rod 24 in linear reciprocating operation is provided on the fixed plate, a first through hole for allowing the driving rod 24 to pass is provided on the box body 4, an L-shaped driving rod 26 is provided on the driving rod 24, a second U-shaped driving frame 27 is provided on the L-shaped driving rod 26, the grinding roller 5 is rotatably connected to the second U-shaped driving frame 27, a passage groove 28 for allowing the grinding roller 5 to pass is provided on the box body 4, and a second through hole for allowing the L-shaped driving rod 26 to pass is provided, and the driving motor is connected to the controller signal. By setting the passage groove 28, the grinding roller 5 collides with the groove wall of the passage groove 28 during operation, generating vibration to the grinding box 7, thereby vibrating the grinding net 9, so that the raw materials blocked in the mesh of the grinding net 9 are separated from the grinding net 9, and the grinding net 9 is prevented from being blocked. The setting of the driving mechanism ensures that two Chinese medicine raw materials with different particle sizes can be ground at the same time. The structure is simple, and the speed can be controlled by the controller, so that two Chinese medicine raw materials with different particle sizes can be ground by one driving mechanism, and the staff does not need to operate two driving mechanisms to drive the grinding, which further reduces the time cost.

[0030] The opening and closing device includes an opening and closing motor 39 disposed on the outer wall of the medicine receiving chamber 12, and an opening and closing shaft 40 disposed on the opening and closing motor 39 and rotatably connected to the two chamber walls of the medicine receiving chamber 12, and an opening and closing plate 41 is disposed on the opening and closing shaft 40. The opening and closing motor is connected to the controller signal.

[0031] The sliding assembly includes a sliding groove 29 provided on the two second plates 2 and along the length direction of the second plates 2, and a first sliding rail provided in the sliding groove 29, on which a first sliding block 30 is provided, and the sliding frame includes two vertical rods 31 vertically provided on the first sliding block 30, and a horizontal rod 32 provided on the top of the two vertical rods 31 and used to connect the two.

[0032] The method of using this embodiment is to load the raw materials into the feed port 5, and the driving mechanism drives the grinding roller 8 to roll and grind the raw materials. The raw materials after rolling and grinding fall into the medicine receiving chamber 10 through the grinding net 9. According to different needs, the raw materials in the medicine receiving chamber 10 are received or transported by controlling the opening and closing device.

[0033] When the raw materials need to be received, the controller sends a signal to the opening and closing motor 39 , and the opening and closing motor 39 drives the opening and closing plate 41 to cover the conveying cavity 13 , so that the raw materials in the medicine receiving cavity 10 enter the receiving cavity 12 .

[0034] When the raw material needs to be transported, the controller sends a signal to the opening and closing motor 39, and the opening and closing motor 39 drives the opening and closing plate 41 to block the receiving chamber 12, so that the raw material in the medicine receiving chamber 10 enters the conveying chamber 13. When the conveying chamber 13 receives the raw material for a predetermined time, the controller sends a reset signal to the drive motor 21 to drive the grinding plate body 19 back to the side of the adjacent drive motor 21, and then the controller sends a start signal to the control valve to make the raw material in the conveying chamber 13 fall onto the grinding net 11, and then the controller sends a signal to the drive cylinder 15 to lift the grinding plate body 19, and sends a signal to the drive motor 21 to drive the grinding plate body 19 to run above the raw material. When the grinding plate body 19 runs above the raw material, the controller sends a falling signal to the drive cylinder 15 to make the grinding plate body contact with the raw material and start grinding. The ground raw material falls to the medicine receiving box 6 through the mesh of the grinding net 11.

[0035] Example 2

[0036] The similarities between this embodiment and embodiment 1 are not repeated here. The difference between the present embodiment and embodiment 1 is as follows: Figure 8-10 As shown, a running frame 33 is provided in the carrying frame, the grinding net 11 is provided in the running frame 33, and the running frame 33 is connected to the second plate body 2 through a plurality of sliding connections. The sliding connections include a fixing groove 34 provided on the side wall of the second plate body 2, a second slide rail 35 is provided in each fixing groove 34, a second slide block 36 is provided on the second slide rail 35, and a plurality of protrusions 37 fixedly connected to the second slide block 36 are provided on the running frame.

[0037] When the operation frame 33 is running, the protrusions and the groove wall of the fixed groove 34 collide back and forth. Since the automatic lifting elastic grinding plate has an elastic squeezing effect on the grinding net 11, it will not have a fixing effect on the grinding net 11. When the protrusions collide with the groove wall of the fixed groove 34, a certain vibration force will be formed on the grinding net, and then a vibration force will be generated on the medicine particles blocked in the mesh of the grinding net, which will not affect the grinding, and at the same time, the medicine particles blocked in the mesh of the grinding net will be separated from the mesh and enter the medicine collection box 6 to prevent the mesh from being blocked. The arrangement of multiple protrusions and multiple groove walls of the fixed groove 34 can further improve the vibration effect and further prevent the mesh from being blocked.

[0038] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
