Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine detection technology, specifically a device for detecting the moisture content of traditional Chinese medicine. Background Technology

[0002] Moisture content testing of traditional Chinese medicine (TCM) is a crucial step in its quality control and storage management. Most TCM herbs originate from natural plants, animals, or minerals, and their moisture content directly affects their efficacy, shelf life, and safety. Excessive moisture content can lead to mold and insect infestation, while insufficient moisture can cause loss of active ingredients and brittleness. Scientifically determining the moisture content of TCM herbs at each stage of production, distribution, and use provides a basis for determining processing, preparation, and storage conditions, ensuring the quality and clinical efficacy of TCM.

[0003] Utility model patent CN220489680U discloses a drying device for Chinese medicinal herbs with moisture detection. This device includes a drying chamber. Pull rods move the levers connected to the sliding plate outwards while simultaneously compressing a spring, facilitating the placement of a weighing tray containing Chinese medicinal herbs into the weighing platform. Releasing the pull rods causes the springs to return, causing the levers connected to the sliding plate to insert into corresponding slots, facilitating the installation and removal of the weighing platform and allowing for easy retrieval of the required moisture content. An electronic scale body with a weighing sensor automatically weighs and stores the data of the Chinese medicinal herbs in the weighing tray. An exhaust fan body with multiple blowers dries the herbs in the weighing tray, and the weighing sensor automatically stores the data again after a second weighing. The moisture content can be calculated from the two weights and viewed on a display screen, facilitating moisture detection of the dried Chinese medicinal herbs.

[0004] This traditional Chinese medicine drying equipment with moisture detection typically involves directly placing whole herbs into the equipment for drying. However, the outer skin of the herbs acts as a barrier, slowing down the migration of internal moisture to the surface. This results in a long evaporation path, low efficiency, and a prolonged drying process. Therefore, we propose a traditional Chinese medicine moisture content detection device. Utility Model Content

[0005] The purpose of this invention is to provide a device for detecting the moisture content of traditional Chinese medicine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A device for detecting the moisture content of traditional Chinese medicine includes a drying weighing instrument with a drying chamber. A medicinal material support assembly is placed in the drying chamber. The medicinal material support assembly includes a tray and two movable blocks that are slidably connected to the left and right sides inside the tray. Several cutting blades are embedded at the end faces of the two movable blocks that are close to each other. The traditional Chinese medicine is placed in the tray between the two movable blocks. By moving the two movable blocks to bring them closer together, the cutting blades can cut the placed medicinal material. The tray has two parallel partitions fixed inside. Pressure strips are installed on the inner walls of the front and rear sides of the left and right ends of the tray. The movable block has protrusions at both ends of the front and rear ends. The two protrusions extend into the bottom of the two pressure strips respectively. The movable block moves laterally along the pressure strips between the two pressure strips. A pair of springs are installed between the movable block and the adjacent partition. The springs provide power for the movable block to return to its original position.

[0007] Preferably, the partition is parallel to the length direction of the movable block, and a placement cavity for placing medicinal materials is formed between the two partitions. Movable cavities are formed between the two partitions and the left and right ends of the tray, and the movable block is located in the movable cavity.

[0010] Preferably, the length of the cutting blade extending out of the movable block is greater than the width of the placement cavity. When the movable block is moved toward the partition, the head of the cutting blade passes through the partition on the near side and then abuts against the surface of the partition on the far side. In this design, the cutting blade's extension length ensures that it completely penetrates the medicinal material inside the cavity, preventing the material from being left uncut due to insufficient length.

[0011] Preferably, a sleeve hole is provided on the end face of the protrusion near the partition, the spring is sleeved in the sleeve hole, a guide post is axially inserted through the sleeve hole, the head of the guide post passes through the axis of the spring and is embedded in the partition, and the tail of the guide post is inserted into the side wall of the tray and fixedly connected to the tray.

[0018] Please see Figures 1-6 The device for detecting the moisture content of traditional Chinese medicine includes a drying weighing instrument 100, which has a drying chamber 110. A herb support assembly 200 is placed in the drying chamber 110. By placing the herb on the herb support assembly 200, the drying weighing instrument 100 can dry the herb. The moisture content of the herb is calculated based on the change in weight before and after drying. The drying weighing instrument 100 is the core support and detection component of the entire device, which can provide the temperature environment required for drying and accurately weigh the herbs. The drying chamber 110 provides a relatively enclosed space for drying the herbs, reducing heat loss. The herb support assembly 200 can stably hold the herbs and also provides an installation foundation for subsequent herb pretreatment.

[0019] like Figure 2 and Figure 3As shown, in this utility model, the medicinal herb support component 200 includes a tray 210 and two movable blocks 220 slidably connected to the left and right sides inside the tray 210. Several cutting blades 222 are embedded at the adjacent end faces of the two movable blocks 220. The medicinal herbs are placed in the tray 210 between the two movable blocks 220. By moving the two movable blocks 220 closer together, the cutting blades 222 can cut the placed medicinal herbs. The tray 210 can support both the medicinal herbs and the movable blocks 220. Both provide installation and movement space. The movable block 220 can slide to move the cutting blade 222. The cutting blade 222 can directly act on the medicinal material to cut the whole medicinal material, destroy the barrier structure of the medicinal material's skin, and shorten the moisture evaporation path during subsequent drying. The top edge of the left and right end faces of the tray 210 is provided with arc-shaped grooves 214. The movable block 220 can be moved by the arc-shaped grooves 214. The arc-shaped grooves 214 make it convenient for the operator to push the movable block 220 to slide by hand, improving the ease of operation.

[0020] like Figure 2 and Figure 3 As shown, specifically, two parallel partitions 211 are fixed inside the tray 210. The partitions 211 are parallel to the length direction of the movable block 220. A placement cavity 212 for placing medicinal materials is formed between the two partitions 211. Movable cavities 213 are formed at the left and right ends of the tray 210 respectively. The movable block 220 is located in the movable cavity 213. The partitions 211 can divide the internal space of the tray 210. The placement cavity 212 formed can limit the position of the medicinal materials to prevent them from shifting during the cutting process and ensure accurate cutting position. The movable cavity 213 provides a dedicated sliding space for the movable block 220 to prevent the movable block 220 from interfering with the medicinal materials or other structures when sliding.

[0021] like Figures 2-5As shown, furthermore, pressure strips 215 are installed on the inner walls of the front and rear sides of the left and right ends of the tray 210. Protrusions 223 are provided at both ends of the movable block 220. The two protrusions 223 extend below the two pressure strips 215 respectively. The movable block 220 moves laterally between the two pressure strips 215. The pressure strips 215 and the protrusions 223 cooperate to restrict the vertical position of the movable block 220, preventing vertical displacement or detachment from the tray 210 during sliding, ensuring stable lateral sliding of the movable block 220. A pair of springs 226 are installed between the movable block 220 and the adjacent partition 211. The springs 226 provide power for the reset of the movable block 220. The springs 226 are compressed when the movable block 220 approaches the partition 211. After the operator releases the movable block 220, the springs 226 can release themselves. The elastic force drives the movable block 220 back to its initial position, eliminating the need for manual reset and improving operational efficiency. A sleeve hole 2231 is provided on the end face of the protrusion 223 near the partition 211. The spring 226 is fitted inside the sleeve hole 2231, which limits the spring 226, preventing lateral displacement during compression or extension and ensuring that the spring 226 always exerts force axially. A guide post 225 is axially inserted through the sleeve hole 2231. The head of the guide post 225 passes through the axis of the spring 226 and is embedded in the partition 211. The tail of the guide post 225 is inserted into the side wall of the tray 210 and fixedly connected to it. The guide post 225 further guides the sliding direction of the movable block 220, ensuring that the movable block 220 always slides in a straight line. It also provides auxiliary limiting for the spring 226, preventing it from bending.

[0022] like Figures 4-6As shown, the movable block 220 is provided with several slots 221 for mounting the cutting blades 222. The tail of the cutting blade 222 is embedded in the slot 221, which can fix the tail of the cutting blade 222 to prevent it from loosening or shifting when cutting the medicinal material, thus ensuring stable cutting force. The cutting blades 222 mounted on the two movable blocks 220 are staggered in the longitudinal direction. The staggered distribution of the cutting blades 222 can make the medicinal material form a more uniform cross-section when it is cut, avoiding excessive local force or incomplete cutting due to the alignment of the cutting blades 222, thus improving the cutting effect. Several through slots 2111 are provided on the surface of the partition 211 along its length. The through slots 2111 are connected to the cutting blades 222 on the corresponding movable blocks 220. The number of blades 222 is equal and their positions correspond one-to-one. The head of the cutting blade 222 can extend out of the through groove 2111. The through groove 2111 provides a channel for the cutting blade 222 to pass through the partition 211, ensuring that when the movable block 220 moves the cutting blade 222 towards the placement cavity 212, the cutting blade 222 can smoothly contact and cut the medicinal material. The length of the part of the cutting blade 222 extending out of the movable block 220 is greater than the width of the placement cavity 212. When the movable block 220 is moved towards the partition 211, the head of the cutting blade 222 passes through the partition 211 located on the near side and then abuts against the surface of the partition 211 on the far side. This length design can ensure that the cutting blade 222 can completely penetrate the medicinal material in the placement cavity 212, avoiding the situation where the medicinal material is not cut due to insufficient length of the cutting blade 222, thus improving the thoroughness of cutting.

[0023] like Figure 4 and Figure 5 As shown, it is worth noting that an insertion hole 2221 is provided on the side surface of the tail of the cutting blade 222, and a slot 224 is provided on the side surface of the movable block 220 corresponding to the position of the insertion hole 2221. The slot 224 extends longitudinally through the movable block 220 and is parallel to the length direction of the movable block 220. An insert strip 227 is inserted into the slot 224. The insert strip 227 passes through the clamping groove 221 and passes through the insertion hole 2221. The insert strip 227 restricts the tail of the cutting blade 222 in the clamping groove 221. The insertion hole 2221, the slot 224 and the insert strip 227 cooperate to fix the cutting blade 222 a second time, further enhancing the stability of the installation of the cutting blade 222. At the same time, it is also convenient to disassemble and replace the damaged cutting blade 222, reducing the maintenance difficulty.

[0024] In this embodiment, when using the herbal moisture content detection device, firstly, the herbal material to be tested is placed in the placement cavity 212 formed by two partitions 211 within the tray 210, ensuring that the herbal material is neatly arranged within the placement cavity 212 without shifting. Then, through the arc-shaped grooves 214 on the top edges of the left and right end faces of the tray 210, the movable block 220 is manually moved towards the partitions 211. The movable block 220 slides laterally under the guidance of the guide post 225 and the limitation of the pressure strip 215 and the protrusion 223, while simultaneously compressing the spring 226. The cutting blade 222 on the movable block 220 then penetrates... The through groove 2111 on the partition 211 extends into the placement cavity 212 to cut the Chinese medicinal material; then, the finger or tool that was moving the movable block 220 is released, and the spring 226 pushes the movable block 220 back to its original position under its own elastic force, and the cutting blade 222 retracts into the movable cavity 213 along with the movable block 220; finally, the medicinal material support assembly 200 containing the cut Chinese medicinal material is placed in the drying cavity 110 of the drying weighing instrument 100, and the drying weighing instrument 100 is started to dry the medicinal material. The drying weighing instrument 100 calculates the moisture content of the medicinal material by detecting the weight change of the medicinal material before and after drying.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
