Description

Technical Field

[0001] This utility model belongs to the field of pretreatment technology for food and medicine homology products, specifically relating to a pretreatment device for testing food and medicine homology products. Background Technology

[0002] Food and medicine of the same origin refers to natural substances that can be used as both food and medicine. In traditional Chinese medicine theory, they are often considered to have dual effects of dietary therapy and medicinal therapy. Among the pretreatment methods for food and medicine of the same origin, crushing and grinding are two common methods, particularly suitable for food or medicine where the extraction of active ingredients is required. Crushing and grinding not only help increase the contact area between the medicinal material and water or other solvents, improving the dissolution rate of its active ingredients and enhancing its medicinal or therapeutic effects, but also facilitate subsequent testing.

[0003] Existing crushing and grinding processes are mostly separate, usually requiring manual operation and transfer from crushing equipment to grinding equipment. This requires more time and labor, not only increasing the number of processing steps but also requiring the coordination of different equipment, which in turn prolongs the total processing time and reduces efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a sample pretreatment device for the detection of food and medicine homology products, which can realize the integration of crushing and grinding, and can adjust the crushing and grinding parameters according to different material properties to ensure the best crushing and grinding effect, thereby adapting to the detection needs of different types of samples.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A sample pretreatment device for detecting food and medicine homology includes a processing device shell, a feed hopper, and a discharge port. The feed hopper is connected to the top of the processing device shell, and the discharge port is located at the bottom of one side of the processing device shell. The processing device shell contains a crushing mechanism and a grinding mechanism. The crushing mechanism includes: crushing rollers, one end of which is connected to the inner wall of the processing device shell via bearings, and the other end of which extends to the front of the processing device shell; two servo motors, each mounted on the front of the processing device shell and fixedly connected to the ends of the two crushing rollers; a connecting frame, which is fitted onto both ends of the surface of the left crushing roller; and a lead screw, threadedly connected to the inner wall of the processing device shell, one end of which is connected to the outside of the connecting frame via bearings, and the other end of which extends to the outside of the processing device shell.

[0007] Preferably, the grinding mechanism includes grinding rollers, a connecting piece, an adjusting rod, a first bevel gear, a rotating motor, a rotating rod, a second bevel gear, and a connecting plate. One end of each of the two grinding rollers is connected to the inner wall of the processing device housing via bearings, and the other end of each of the two grinding rollers extends to the front side of the processing device housing. Both grinding rollers are located at the bottom of the two crushing rollers. The connecting piece is sleeved on both ends of the surface of the left grinding roller. The adjusting rod is threaded to the inner wall of the processing device housing. One end of the adjusting rod is connected to the outside of the connecting piece via bearings, and the other end of the adjusting rod extends to the outside of the processing device housing. The two first bevel gears are respectively fixedly connected to the front ends of the two grinding rollers. The rotating motor is fixedly installed on the front side of the processing device housing. The rotating rod is fixedly connected to the output end on one side of the rotating motor. The second bevel gears are each sleeved on the surface of the rotating rod. The second bevel gears are respectively meshed with the first bevel gears and are arranged opposite to each other. One end of the connecting plate is fixedly connected to one side of the left second bevel gear, and the other end of the connecting plate extends through the processing device housing and is fixedly connected to the connecting piece.

[0008] Preferably, both ends of the crushing roller and grinding roller on the left are fitted with sliding blocks, the servo motor on the left is fixedly connected to the sliding blocks, the sliding blocks on the front are fixedly connected to the connecting frame and the connecting piece respectively, the rear side of the inner wall of the processing device housing is provided with sliding grooves that cooperate with the sliding blocks, the front side of the processing device housing is provided with slots, and the sliding blocks are slidably connected to the inside of the slots respectively.

[0009] Preferably, the inner wall of the second bevel gear on the left side is provided with a groove, and the surface of the rotating rod is fixedly connected with a protrusion that mates with the groove.

[0010] Preferably, a guide plate is fixedly connected to the inner wall of the processing device housing. The guide plate is located at the bottom of the two crushing rollers, and the two guide plates are installed in an inverted triangular shape.

[0011] Preferably, a guide plate is fixedly connected to the inner wall of the processing device housing, and one end of the guide plate extends through to the inner wall of the discharge port and is inclined.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, when processing materials, the material is first fed into the two crushing rollers inside the processing device housing through the feed hopper. Then, two servo motors are simultaneously activated, rotating clockwise and counterclockwise respectively, which in turn drives the two crushing rollers to rotate inwards, thus crushing the material between the rollers. The distance between the two crushing rollers can also be adjusted according to different materials. During adjustment, the lead screw is rotated, causing the connecting frame and sliding block to move parallel within the slot and sliding groove. This parallel movement of the connecting frame drives the servo motor on the left and the crushing roller to move horizontally. This allows for adjustment of crushing parameters according to different material characteristics, saving time, improving overall pre-processing efficiency, and ensuring optimal crushing results. This flexibility makes the equipment suitable for various medicinal and edible homologous products, avoiding the limitations of fixed parameter processing, and thus adapting to the testing needs of different types of samples.

[0014] In this invention, after the material is crushed, it automatically falls downwards and settles between two grinding rollers. Simultaneously, a rotating motor is activated, which drives a rotating rod and two second bevel gears to rotate. The rotation of the two second bevel gears simultaneously drives two meshing first bevel gears to rotate, which in turn drives the two grinding rollers to rotate inwards, further grinding the crushed material. This achieves integrated crushing and grinding. Through precise crushing and grinding, the integrated equipment ensures the uniformity and appropriate particle size of the sample, providing a more reliable sample for subsequent testing and improving the accuracy and repeatability of the test results.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-5As shown, a sample pretreatment device for detecting food and medicine homology includes a processing device housing 1, a feed hopper 101, and a discharge port 102. The feed hopper 101 is connected to the top of the processing device housing 1, and the discharge port 102 is located at the bottom of one side of the processing device housing 1. A crushing mechanism and a grinding mechanism are arranged inside the processing device housing 1. The crushing mechanism includes: crushing rollers 201, one end of each of the two crushing rollers 201 is connected to the inner wall of the processing device housing 1 via bearings, and the other end of each of the two crushing rollers 201 extends to the front side of the processing device housing 1; and two servo motors 202, both mounted on the front side of the processing device housing 1 and connected to the two crushing rollers 201 respectively. The end of the crushing roller 201 is fixedly connected; a connecting frame 203 is sleeved on both ends of the surface of the left crushing roller 201; a lead screw 204 is threaded to the inner wall of the processing device housing 1, one end of the lead screw 204 is connected to the outside of the connecting frame 203 through a bearing, and the other end of the lead screw 204 extends to the outside of the processing device housing 1. The grinding mechanism includes a grinding roller 301, a connecting piece 302, an adjusting rod 303, a first bevel gear 304, a rotating motor 305, a rotating rod 306, a second bevel gear 307, and a connecting plate 308. One end of each of the two grinding rollers 301 is connected to the inner wall of the processing device housing 1 through a bearing. The other ends of the grinding rollers 301 extend to the front side of the processing device housing 1. Both grinding rollers 301 are located at the bottom of the two crushing rollers 201. The connecting piece 302 is sleeved on both ends of the surface of the left grinding roller 301. The adjusting rod 303 is threaded to the inner wall of the processing device housing 1. One end of the adjusting rod 303 is connected to the outside of the connecting piece 302 through a bearing. The other end of the adjusting rod 303 extends to the outside of the processing device housing 1. Two first bevel gears 304 are respectively fixedly connected to the front ends of the two grinding rollers 301. The rotating motor 305 is fixedly installed on the front side of the processing device housing 1. The rotating rod 306 is fixedly connected to the output end of one side of the rotating motor 305. The second bevel gears 307 are all sleeved on the surface of the rotating rod 306. The second bevel gears 307 are respectively meshed with the first bevel gears 304 and are arranged opposite each other. One end of the connecting plate 308 is fixedly connected to one side of the second bevel gear 307 on the left side, and the other end of the connecting plate 308 passes through the outer shell 1 of the processing device and is fixedly connected to the connecting piece 302. Through the crushing mechanism and the grinding mechanism, the two tasks can be combined, making the pretreatment of materials more concentrated and efficient, reducing physical loss, and also having a flexible adjustment function, which can adapt to the processing needs of different medicinal materials or food ingredients, avoiding the limitations brought about by fixed parameter processing, and enhancing the consistency of sample processing and the reliability of subsequent testing.

[0024] like Figure 2 and Figure 4As shown, sliding blocks 401 are fitted at both ends of the left crushing roller 201 and the grinding roller 301. The left servo motor 202 is fixedly connected to the sliding block 401. The front sliding block 401 is fixedly connected to the connecting frame 203 and the connecting piece 302 respectively. The rear side of the inner wall of the processing device housing 1 is provided with sliding grooves 402 that cooperate with the sliding blocks 401. The front side of the processing device housing 1 is provided with slots 403. The sliding blocks 401 are slidably connected to the inside of the slots 403 respectively. When the screw 204 is rotated to adjust the distance between the two crushing rollers 201 and the two grinding rollers 301 by adjusting the adjusting rod 303, the left... The side crushing roller 201 and the grinding roller 301 can respectively drive the sliding block 401 to slide inside the sliding groove 402, which can realize the parallel movement of the two and prevent displacement due to lack of limiting assistance when adjusting the left crushing roller 201 and the grinding roller 301. When the sliding block 401 slides, it can have sufficient movement space with the cooperation of the sliding groove 402 and the groove opening 403, which avoids the sliding block 401 from colliding with the outer shell 1 of the processing device due to insufficient movement space. At the same time, an elastic baffle can be installed on the front side of the inner wall of the groove opening 403 to prevent the material from leaking to the outside through the groove opening 403 during processing.

[0025] like Figure 5 As shown, the inner wall of the second bevel gear 307 on the left side is provided with a groove 501. The surface of the rotating rod 306 is fixedly connected with a protrusion 502 that engages with the groove 501. When the distance between the grinding rollers 301 is adjusted by rotating the adjusting rod 303, the rotation of the adjusting rod 303 will cause the connecting piece 302 to move horizontally. The horizontal movement of the connecting piece 302 will cause the sliding block 401 and the connecting plate 308 to move. The connecting plate 308 will also cause the second bevel gear 307 on the left side to move horizontally under the cooperation of the groove 501 and the protrusion 502. Under the cooperation of the protrusion 502 and the groove 501, the connecting rod can drive the second bevel gear 307 to rotate, and the second bevel gear 307 can also move horizontally on the surface of the rotating rod 306.

[0026] like Figures 3-4 As shown, a guide plate 6 is fixedly connected to the inner wall of the processing device housing 1. The guide plate 6 is located at the bottom of the two crushing rollers 201. The two guide plates 6 are installed in an inverted triangle. The setting of the guide plate 6 can effectively guide the direction of the flow of the crushed material, so that the material falls effectively between the two grinding rollers 301, and can ensure that the material is evenly distributed after crushing, avoiding local accumulation or uneven grinding.

[0027] like Figures 3-4As shown, a guide plate 7 is fixedly connected to the inner wall of the outer shell 1 of the processing device. One end of the guide plate 7 extends through to the inner wall of the discharge port 102 and is inclined. The guide plate 7 can effectively guide the flow direction of the ground material in the processing device, ensuring that the material is not easily blocked when discharged. The guide plate 7 smoothly guides the material to the discharge port 102, effectively reducing the retention of material during the discharge process and ensuring the efficient discharge of the equipment.

[0028] The working principle of this utility model is as follows: When processing materials, the materials can first be fed into the two crushing rollers 201 inside the outer shell 1 of the processing device through the feed hopper 101. Then, two servo motors 202 are run simultaneously. After the two servo motors 202 start running, they rotate clockwise and counterclockwise respectively, which will drive the two crushing rollers 201 to rotate inward at the same time, so as to crush the materials between the crushing rollers 201. At the same time, the distance between the two crushing rollers 201 can be adjusted according to different materials. When adjusting, the lead screw 204 is rotated. The rotation of the lead screw 204 will drive the connecting frame 203 and the sliding block 401 to move parallel inside the slot 403 and the sliding groove 402. When the connecting frame 203 moves parallel, it will drive the servo motor 202 on the left and the crushing roller 201 to move in parallel. 1. After the material is crushed, it will automatically fall downwards and fall between the two grinding rollers 301. At the same time, the rotating motor 305 is activated. The rotating motor 305 drives the rotating rod 306 and the two second bevel gears 307 to rotate. The rotation of the two second bevel gears 307 can simultaneously drive the two meshing first bevel gears 304 to rotate. The rotation of the two first bevel gears 304 can simultaneously drive the two grinding rollers 301 to rotate inwards, and will further grind the crushed material. This achieves integrated crushing and grinding. Through precise crushing and grinding, the integrated equipment can ensure the uniformity and appropriate particle size of the sample, thereby providing a more reliable sample for subsequent testing and improving the accuracy and repeatability of the test results.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
