Abstract
Description
Technical Field
[0001] The utility model relates to the field of Chinese medicinal material detection, in particular to a Chinese medicinal material component spectrum detection device. Background Art
[0002] When testing Chinese medicinal materials, it is necessary to analyze them through spectral detection instruments, which use spectral technology to perform non-destructive testing on Chinese medicinal materials. By measuring the absorption, reflection or scattering characteristics of Chinese medicinal materials to light of different wavelengths, information about the ingredients of Chinese medicinal materials can be obtained, which helps to ensure the quality and safety of Chinese medicinal materials.
[0003] At present, when using a spectrometer to detect Chinese medicinal materials, the Chinese medicinal materials need to be placed on the surface of the sample table inside the instrument. However, due to the small space of the instrument sample table, it is inconvenient for the operator to flatten the Chinese medicinal materials on the sample table. At this time, the Chinese medicinal materials are piled up on the surface of the sample table. The accumulation of Chinese medicinal materials will cause inconsistent propagation paths of light in the sample, excessive light absorption in some areas, and insufficient light absorption in other areas. At this time, the detected spectral signal will be unstable and have poor repeatability, thereby affecting the accuracy of quantitative and qualitative analysis. Therefore, a spectral detection device for Chinese medicinal material components is proposed to address the above problems. Utility Model Content

[0025] Reference Figure 2 - Figure 3 The placement component 4 includes a placement cavity 41 located inside the inner cavity 3, and pull rods 42 are fixedly installed on the left and right sides of the top of the placement cavity 41, and bottom grooves 43 are opened on the front and back sides of the bottom end of the placement cavity 41. Support rods 44 are fixedly installed on the front and back sides of the bottom wall of the placement cavity 41, and a buffer spring 45 is fixedly installed on one end of the support rod 44 close to the inner wall of the placement cavity 41. A convex block that is adapted to be engaged with the bottom groove 43 is fixedly installed at the bottom end of the inner cavity 3, and the convex block is helpful for limiting the position of the placement cavity 41. One end of the buffer spring 45 away from the support rod 44 is adapted to contact with the inner wall of the placement cavity 41, and a holding cavity 46 is fixedly installed on the top of the support rod 44, and an annular plate 47 is fixedly installed on the bottom end of the holding cavity 46;
[0026] A motor 51 is fixedly installed at the center of the bottom wall of the placement cavity 41, and an eccentric plate 52 is fixedly installed on the output shaft at the top of the motor 51. Support sleeves 53 are fixedly installed on the front and rear sides of the bottom wall of the placement cavity 41. A sliding rod 54 is slidably connected inside the support sleeve 53, and a reset spring 55 is fixedly installed inside the bottom end of the sliding rod 54. The eccentric plate 52 and the output shaft of the motor 51 are eccentrically connected, and one end of the reset spring 55 away from the sliding rod 54 is fixedly installed on the surface of the support sleeve 53, one end of the sliding rod 54 is in adaptable contact with the eccentric plate 52, and the other end of the sliding rod 54 is in adaptable contact with the annular plate 47. After the motor 51 drives the eccentric plate 52 to rotate, the eccentric plate 52 will periodically push the sliding rod 54, and at this time, the sliding rod 54 will periodically push the annular plate 47 to vibrate the containing cavity 46.
[0027] Reference Figure 4 - Figure 5The dust cleaning assembly 6 includes a cleaning tube 61 fixedly installed at the front and rear ends of the containing cavity 46, a negative pressure fan 62 is fixedly installed inside the cleaning tube 61, a collecting bag 63 is fixedly installed at one end of the cleaning tube 61 close to the outside of the containing cavity 46, a winding rope 64 is fixedly installed on the surface of the cleaning tube 61, a fixing rod 65 is fixedly installed on the outer wall of the containing cavity 46, a winding sleeve 66 is rotatably connected to the surface of the fixing rod 65, a telescopic rod 67 is fixedly installed on the outer wall of the containing cavity 46, the winding rope 64 is sleeved on the surface of the collecting bag 63, and the side of the winding rope 64 away from the collecting bag 63 is wound around and connected to the surface of the winding sleeve 66, and a card slot that is adapted to be engaged with the telescopic rod 67 is opened on the surface of the winding sleeve 66. The telescopic rod 67 can be extended to be engaged with the inside of the winding sleeve 66, and the winding sleeve 66 is limited by the friction between the telescopic rod 67 and the winding sleeve 66.
[0028] Working principle: The operator places the Chinese medicinal materials to be tested inside the holding cavity 46, and then drives the motor 51 to operate. The motor 51 will drive the eccentric plate 52 to rotate, and when the eccentric plate 52 rotates, it will periodically push the sliding rod 54, so that the sliding rod 54 moves the compressed reset spring 55 inside the support sleeve 53, and at this time the sliding rod 54 will push the annular plate 47, so that the annular plate 47 drives the holding cavity 46 to compress the buffer spring 45 and move toward the inner wall edge of the placement cavity 41, and at this time the holding cavity 46 will drive the support rod 44 to compress the buffer spring 45, and then the eccentric plate 52 continues to rotate and moves away from the sliding rod 54, at this time the annular plate 47 is no longer pushed by the sliding rod 54, so the annular plate 47 and the holding cavity 46 will move toward the center of the placement cavity 41 under the action of the rebound force of the buffer spring 45, so that the reciprocating holding cavity 46 swings back and forth, so that the Chinese medicinal materials contained inside are spread flat on the bottom of the holding cavity 46.
[0029] While placing the Chinese medicinal materials in the containing cavity 46, dust may fly inside the containing cavity 46. At this time, the operator drives the negative pressure fan 62 to operate. The negative pressure fan 62 absorbs the dust inside the containing cavity 46 into the inside of the cleaning tube 61 and then moves it to the inside of the collecting bag 63 to be collected. When the detection is completed, the operator can shorten the telescopic rod 67 to separate it from the winding sleeve 66, and then rotate the winding sleeve 66 to loosen the winding rope 64, so that the collecting bag 63 is no longer tightened to the surface of the cleaning tube 61 by the winding rope 64. At this time, the collecting bag 63 can be removed to deal with the dust inside.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
