[0001] The utility model relates to the technical field of traditional Chinese medicine, in particular to a device for slicing and grading traditional Chinese medicine. Background Art

[0002] The drugs that are collected, processed, prepared under the guidance of traditional Chinese medicine theory, explain the mechanism of action, and guide clinical application are collectively called traditional Chinese medicine. In order to improve the efficacy, facilitate processing, and be conducive to storage and identification, etc., it is necessary to slice traditional Chinese medicine.

[0003] In the existing device for slicing and grading traditional Chinese medicine, when slicing and grading traditional Chinese medicine, the speed is slow, resulting in low production efficiency.

[0004] A Chinese patent with the publication number of CN213352599U was proposed in the prior art to solve the above-mentioned existing technical problems. The technical solution disclosed in this patent document is as follows: A device for slicing and grading traditional Chinese medicine, including a bottom plate, springs, a traditional Chinese medicine slicing unit, and a rotating shaft control unit; Bottom plate: A support rod is fixedly connected to the left side of the upper surface, and there are four support rods and they are evenly distributed. The upper part of the support rod on the left side is rotatably connected to a rotating shaft. The front side of the rotating shaft passes through the front support rod. A rotating cylinder is fixedly sleeved on the side surface of the rotating shaft. A conveyor belt is installed on the side surface of the rotating cylinder. The upper parts of two support shafts are rotatably connected to the support rods on the right side. The two support shafts cooperate with the inner side surface of the conveyor belt. A first fixing plate is fixedly connected to the support rod at the rear right side. A second fixing plate is fixedly connected to the front side of the upper surface of the bottom plate; Springs: Fixedly connected to the right side of the upper surface of the bottom plate, and there are four springs and they are evenly distributed; When this device for slicing and grading traditional Chinese medicine slices and grades traditional Chinese medicine, the speed is fast and the production efficiency can be improved. However, there will still be a problem that because there is a certain distance between the grading structure and the slicing structure of this device, the sliced traditional Chinese medicine will fall from a high place onto the grading structure, which is likely to cause damage to the traditional Chinese medicine and affect the subsequent processing and use of the traditional Chinese medicine. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for slicing and grading traditional Chinese medicine to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0007] A traditional Chinese medicine slicing and grading device includes a conveying frame; a controller is fixedly installed at one end of the conveying frame. A pair of rollers are rotatably installed inside the conveying frame through bearings. A conveyor belt is arranged inside the conveying frame, and the conveyor belt is sleeved around the periphery of each roller. A motor is fixedly installed at one end of the conveying frame on one side of the controller, and the output shaft of the motor is fixedly connected to one end of the roller on one side inside the conveying frame. A fixed frame is fixedly installed on the top of the conveying frame, and a hydraulic rod is fixedly installed on the top of the fixed frame. The output shaft of the hydraulic rod penetrates through the bottom of the fixed frame and is fixedly installed with a cutting knife. A limiting component for restricting the quantity of the conveyed traditional Chinese medicine materials is arranged on the other side of the cutting knife. A material guiding plate inclined towards the bottom on the other side is fixedly installed inside the conveying frame on the other side of the top of the conveyor belt, and the material guiding plate is attached to the outer surface of the conveyor belt. A protective frame is arranged on the other side of the conveying frame, and the protective frame is fixedly connected to the outer surface of the outer end of the conveying frame. A first sieve plate inclined towards the bottom on the other side is fixedly installed inside the protective frame at the bottom of the conveyor belt. A second sieve plate inclined towards the bottom on one side is fixedly connected inside the protective frame at the bottom of the first sieve plate. A material guiding frame inclined towards the bottom at the other end is fixedly installed inside the protective frame at the top of the first sieve plate. A guiding frame inclined towards the bottom at one end is fixedly connected inside the protective frame at the top of the material guiding frame. The guiding frame is located at the bottom of the material guiding plate. A guiding roller group inclined towards the bottom on the other side is rotatably installed inside the protective frame between the first sieve plate and the second sieve plate.

[0008] By installing the material guiding plate, the sliced traditional Chinese medicine can be guided to the top of the guiding frame. At the same time, during the rotation of the conveyor belt, the material guiding plate can scrape the outer surface of the conveyor belt, thereby avoiding the adhesion of the traditional Chinese medicine to the outer surface of the conveyor belt and affecting the subsequent grading effect. By installing the guiding frame, the traditional Chinese medicine can be guided towards one end, enabling the traditional Chinese medicine to fall onto the top of the material guiding frame and finally onto the top of the first sieve plate. Among them, by installing the guiding frame and the material guiding frame, the falling time of the traditional Chinese medicine can be extended, thus avoiding the damage of the traditional Chinese medicine due to directly falling from a high place onto the top of the first sieve plate, and playing a buffering and protective effect on the traditional Chinese medicine. Among them, by setting the first sieve plate to be inclined towards the bottom at one end, after the traditional Chinese medicine falls onto the top of the first sieve plate through the material guiding frame, the traditional Chinese medicine can slide along the first sieve plate towards the bottom at one end, thereby avoiding the large accumulation of the traditional Chinese medicine on the top of the first sieve plate at the bottom of the other end of the material guiding frame, resulting in the inability of the traditional Chinese medicine piled up at a high place to be normally screened, and further avoiding affecting the grading and screening effect of the traditional Chinese medicine. The traditional Chinese medicine passing through the first sieve plate can fall onto the top of the guiding roller group, then slide towards the other side along the guiding roller group, and then fall onto the top of the second sieve plate. Among them, by installing the guiding roller group, the falling trajectory of the traditional Chinese medicine can be guided and limited, avoiding the traditional Chinese medicine directly falling from a position near one side of the top of the first sieve plate onto the top of the second sieve plate and being damaged due to too long a distance, and further playing a buffering and protective effect on the traditional Chinese medicine.

[0009] A further improvement of the technical solution of the present utility model lies in that: several first rollers are rotatably installed inside the guiding frame.

[0010] Adopting the above technical solution, in this solution, when the Chinese medicinal materials slide along the top of the guiding frame, the first rollers can rotate following the Chinese medicinal materials through installation, thereby reducing the friction between the surface of the guiding frame and the Chinese medicinal materials and reducing the wear of the guiding frame on the Chinese medicinal materials. When the Chinese medicinal materials fall onto the top of the guiding frame.

[0011] A further improvement of the technical solution of the present utility model lies in that: a first rubber sleeve is attached to the periphery of each first roller.

[0012] Adopting the above technical solution, in this solution, by installing the first rubber sleeve, the reverse force of the surface of the first roller on the Chinese medicinal materials can be reduced, and thus a buffering and protecting effect on the Chinese medicinal materials is achieved.

[0013] A further improvement of the technical solution of the present utility model lies in that: several second rollers are rotatably installed inside the material guiding frame.

[0014] Adopting the above technical solution, in this solution, when the Chinese medicinal materials slide along the top of the material guiding frame, the second rollers can rotate following the Chinese medicinal materials through installation, thereby reducing the friction between the surface of the material guiding frame and the Chinese medicinal materials and reducing the wear of the material guiding frame on the Chinese medicinal materials. When the Chinese medicinal materials fall onto the top of the material guiding frame.

[0015] A further improvement of the technical solution of the present utility model lies in that: a second rubber sleeve is attached to the periphery of each second roller.

[0016] Adopting the above technical solution, in this solution, by installing the second rubber sleeve, the reverse force of the surface of the second roller on the Chinese medicinal materials can be reduced, and thus a buffering and protecting effect on the Chinese medicinal materials is achieved.

[0017] A further improvement of the technical solution of the present utility model lies in that: a third rubber sleeve is attached to the outer surface of the guiding roller group.

[0018] Adopting the above technical solution, in this solution, when the Chinese medicinal materials fall onto the top of the guiding roller group, by installing the third rubber sleeve, the reverse force of the surface of the guiding roller group on the Chinese medicinal materials can be reduced, and a buffering and protecting effect on the Chinese medicinal materials is achieved.

[0019] A further improvement of the technical solution of the present utility model lies in that: the limiting member includes a limiting frame, a limiting roller is rotatably installed inside the limiting frame, a spring group is fixedly installed at the top of the limiting frame, and the top of the spring group is fixedly connected to the bottom of the fixed frame.

[0020] With the above technical solution, in this solution, during the process of the traditional Chinese medicine moving to the other side along the conveyor belt, by installing a limiting roller, the height of the sliced traditional Chinese medicine passing through the bottom of the limiting roller can be restricted from the top, so that the traditional Chinese medicine higher than the bottom of the limiting roller falls to the top of the conveyor belt on one side and then moves to the other side. Furthermore, it can prevent the sliced traditional Chinese medicine from piling up upward and directly passing through the first sieve plate, making it impossible for the traditional Chinese medicine piled up on the top to be normally classified and sieved. Among them, by installing a spring group, the pressure of the limiting roller on the traditional Chinese medicine can be buffered, preventing the pressure of the limiting roller on the traditional Chinese medicine from being too large and damaging the traditional Chinese medicine, and thus being able to buffer and protect the traditional Chinese medicine.

[0021] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0022] 1. The present utility model provides a traditional Chinese medicine slicing and grading device. Through the mutual cooperation among the guide plate, the guiding frame and the feeding frame, the falling time of the traditional Chinese medicine can be prolonged, thereby avoiding the damage caused by the direct fall of the traditional Chinese medicine from a high place to the top of the first sieve plate. By installing a guiding roller group, the falling trajectory of the traditional Chinese medicine can be guided and limited, preventing the traditional Chinese medicine from directly falling from a position near one side of the top of the first sieve plate to the top of the second sieve plate, because the falling distance is too far and causing damage to the traditional Chinese medicine, thus playing a role in buffering and protecting the traditional Chinese medicine.

[0023] 2. The present utility model provides a traditional Chinese medicine slicing and grading device. By installing the first rotating roller and the second rotating roller respectively, the friction between the surfaces of the guiding frame and the feeding frame and the traditional Chinese medicine can be reduced, thereby reducing the wear of the guiding frame on the traditional Chinese medicine and playing a role in buffering and protecting the traditional Chinese medicine. And by installing the first rubber sleeve, the second rubber sleeve and the third rubber sleeve respectively, the reverse extrusion force of the outer surfaces of the first rotating roller, the second rotating roller and the guiding roller group on the traditional Chinese medicine can be reduced, further playing a role in buffering and protecting the traditional Chinese medicine.

[0024] 3. The present utility model provides a traditional Chinese medicine slicing and grading device. By setting a limiting component, the height of the sliced traditional Chinese medicine passing through the bottom of the limiting roller can be restricted from the top, preventing the sliced traditional Chinese medicine from piling up upward and directly passing through the first sieve plate for sieving, making it impossible for the traditional Chinese medicine piled up on the top to be normally classified and sieved, thus improving the subsequent sieving effect of the traditional Chinese medicine.

[0036] Embodiment 2

[0037] As Figure 2 、 Figure 3 and Figure 4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a plurality of first rollers 601 are rotatably installed inside the guiding frame 6, and a first rubber sleeve 602 is attached to the periphery of each first roller 601.

[0039] Embodiment 3

[0040] As Figure 1 and Figure 5 As shown, on the basis of Embodiment 2, the present utility model provides a technical solution: Preferably, the limiting component 5 includes a limiting frame 501, a limiting roller 502 is rotatably installed inside the limiting frame 501, and a spring group 503 is fixedly installed on the top of the limiting frame 501, and the top of the spring group 503 is fixedly connected to the bottom of the fixed frame 3.

[0041] In this embodiment, during the process of the Chinese medicine moving to the other side along with the conveyor belt 9, by installing the limiting roller 502, the height of the sliced Chinese medicine passing through the bottom of the limiting roller 502 can be restricted from the top, so that the Chinese medicine higher than the bottom of the limiting roller 502 falls to the top of the conveyor belt 9 on one side and then moves to the other side.

Among them, the traditional Chinese medicine higher than the bottom of the limiting roller 502 falls to the top of the conveyor belt 9 on one side, and then the conveyor belt 9 continues to drive the traditional Chinese medicine to move to the other side. After the sliced traditional Chinese medicine moves to the top of the guide plate 101, it can be guided to the top of the guide frame 6. The guide frame 6 guides the traditional Chinese medicine to one end, making it fall to the top of the guide frame 7, and finally fall to the top of the first sieve plate 11. The first sieve plate 11 can be used to screen the traditional Chinese medicine. Those with a volume larger than the sieve holes of the first sieve plate 11 slide out to the other side for discharging, and those with a volume smaller than the sieve holes of the first sieve plate 11 fall downward to the top of the guide roller group 13, then slide to the other side along the guide roller group 13, and then fall to the top of the second sieve plate 12. The second sieve plate 12 is used to screen the traditional Chinese medicine again. Those with a volume larger than the sieve holes of the second sieve plate 12 slide out to one side for discharging, and those with a volume smaller than the sieve holes of the first sieve plate 11 pass through the second sieve plate 12 for discharging treatment, thus completing the grading and screening work of the traditional Chinese medicine.
