Description

Technical Field

[0001] The present invention relates to the field of cashmere fiber detection, and in particular to a cashmere fiber detection device and method based on near infrared spectroscopy. Background Art

[0002] Cashmere fiber is a high-grade natural animal fiber. Cashmere fiber is the down taken from goats, mainly produced from cashmere goats. Cashmere fiber is composed of a scale layer and a cortex layer, without a medullary layer. The scale layer is thinner and covers the fiber surface in a ring or oblique strip shape. The scale edges are smoother and the arrangement is tighter and more even than wool scales, which makes the surface of the cashmere fiber smoother and softer.

[0003] Cashmere fiber testing In order to ensure the quality of cashmere and avoid adulteration, cashmere fiber products need to be tested. Traditional cashmere fiber testing uses near-infrared spectroscopy to irradiate cashmere fibers, and then compares the light dispersion data after irradiation with the existing accurate database to achieve cashmere fiber detection. However, this detection method is single and only uses a single type of light for irradiation, which results in insufficient data. Existing detection equipment makes it difficult to automatically switch between multiple lights for cashmere fiber detection.

[0064] S5: The combined transmission disk 4 rotates for the third week to drive the three-light switching disk 5 to rotate, and then the combined transmission disk 4 completes the third week of rotation to complete the acquisition of three-light detection data;

[0065] S6: Turn off the servo motor 36, start the first motor 225 to drive the sample pressing plate 22 to move upward, replace the sample to be tested and put it into the square seat 21, and then the three-light switching disk 5 switches the three-color detection light during the combination transmission disk 4 rotates three times;

[0066] S7: After the sample test is completed, the three-color data in the computer is compared to obtain the cashmere fiber test results.

[0067] The use process of the cashmere fiber detection device based on near infrared spectroscopy provided by the present invention is as follows:

[0068] Take the standard test piece of cashmere fiber and place it on the top of the chuck 211, start the first motor 225, and the dual first motors 225 start to drive the synchronous gear 224 to rotate. The rotation of the synchronous gear 224 drives the transmission gear block 223 engaged with it to move. The transmission gear block 223 is forced to move and will drive the four groups of columns 222 to descend. The descent of the columns 222 drives the sample pressing plate 22 to move downward. When the sample pressing plate 22 moves down to the upper part of the square base 21 and compacts the sample, the sample will be tightened and fit on the surface of the lens 213 under the pressure of the tensioning block 221.

[0069] After the sample pressing plate 22 is moved downward, the column 222 is driven to move downward and penetrate into the combination socket 43 .

[0070] At this time, the servo motor 36 is started, and the servo motor 36 drives the driving bevel gear 361 connected to its output end to rotate. The driving bevel gear 361 rotates and drives the lower disc chasing gear ring engaged with it to rotate. The lower disc chasing gear ring drives the combined transmission disk 4 connected to its upper part to rotate. The combined transmission disk 4 rotates inside the limiting rotation groove 132 through the disk body limiting ring 41. When the combined transmission disk 4 rotates, it will drive the combined sample pool 2 to rotate through the column 222, so that the sample rotates.

[0071] After the sample is pressed through the combined sample pool 2, the light area 56 and the servo motor 36 are started synchronously. After the light area 56 is started, the detection light will be irradiated on the surface of the cashmere fiber through the light guide mirror 55 to detect it. When the servo motor 36 is started to drive the combined transmission disk 4 to rotate, the detection light can detect the circumferential position of the cashmere fiber, thereby increasing the detection area of ​​the cashmere fiber and improving the accuracy of the detection result of the cashmere fiber.

[0072] When the combined transmission disc 4 rotates one circle at the tail end, the cut-in arc plate 44 on the bottom surface of the combined transmission disc 4 will abut against the driven arc block 34. As the combined transmission disc 4 continues to rotate, the driven arc block 34 will be forced to push the transmission main shaft 3 to slide inside the power conversion cylinder 6.

[0073] During the sliding of the transmission main shaft 3 , the lamp-changing bevel gear 33 connected to the outer wall of the transmission main shaft 3 will be positioned in place, and slide inside the second limiting groove 332 through the sliding block 333 in the groove.

[0074] The partition baffle 31 at the other end of the outer wall of the transmission main shaft 3 will move with it, and the wear-resistant sheet 322 will be blocked by the main shaft transmission seat, and slide within the rebound area 32 through the first limiting groove 321, and at the same time apply pressure to the reset spring 323.

[0075] The combined driven plate 37 connected to the end of the transmission main shaft 3 will be inserted deep into the telescopic area 61. As the combined driving plate 62 rotates, the combined driving plate 62 will drive the combined driven plate 37 to rotate, thereby completing the rotation of the transmission main shaft 3.

[0076] The rotation of the transmission main shaft 3 will drive the partition baffle 31, the wear-resistant sheet 322, and the return spring 323 connected to the surface thereof to rotate, and at the same time drive the lamp-changing bevel gear 33 to rotate.

[0077] The lamp changing bevel gear 33 rotates in a limited manner within the L-shaped rotating groove 354 through the L-shaped rotating ring 331, so that the lamp changing bevel gear 33 can rotate along with the transmission main shaft 3 while ensuring that the lamp changing bevel gear 33 does not move.

[0078] The rotation of the transmission main shaft 3 will drive the plate chasing gear ring meshing with it to rotate, and the rotation of the plate chasing gear ring will drive the bottom plate 51 under the disk to rotate. The rotation of the bottom plate 51 under the disk will be limited and rotated at the center of the support platform 355 on the seat through the limiting groove 52 in the plate.

[0079] The rotation of the bottom plate 51 under the disk will synchronously drive the three-light switching disk 5 to rotate. The rotation of the three-light switching disk 5 will switch the lighting area 56 on its top surface. When the lighting area 56 is switched and the light guide mirror 55 is closed, the combined transmission disk 4 will drive the cutting arc plate 44 to rotate until it is separated from the driven arc block 34.

[0080] At this time, the transmission main shaft 3 is reversely displaced by the thrust of the return spring 323, and the combined driven plate 37 is separated from the combined driving plate 62, so that the driving motor alone drives the combined transmission disk 4 to rotate, completing the near-infrared light detection of the sample inside the combined sample pool 2 by the second lighting area 56.

[0081] As the combined transmission disc 4 continues to rotate, in the third cycle, the light zone 56 will rotate to the third light zone 56, completing three rounds of testing of the sample. When the testing is completed, the testing box 1 will import the test results into the database through electrical signals.

[0082] Then, the first motor 225 is started to open the sample pressing plate 22, so that the upper part of the sample chuck 211 is opened, and the sample is taken out and replaced with the sample to be tested, so that the sample can be tested in multiple rounds with high precision, thereby ensuring the accuracy of the cashmere fiber test results.
