The positioning frame 65 slides and guides in the movable plate 52 to absorb the high-frequency vibration generated by ultrasonic cutting. The material of the damping ring 21 has both elasticity and damping properties to reduce the influence of equipment vibration on positioning accuracy.

[0043] Working principle: When in use, first move the pressing rod 102 upward to separate it from the automatic tightening device 101, then wind one end of the textile to be sampled around the hanging rod 16 of the removal ring 105, and then wind the other end around the take-up ring 104. Since the removal ring 105 can be removed by moving the pressing rod 102 upward, the textile to be sampled can be wound around the removal ring 105 in advance for use, and then the pressing rod 102 is reset and moved, so that the front end of the bottom of the pressing rod 102 is engaged with the front end of the top of the automatic tightening device 101 to limit the take-up ring 104, avoiding To avoid the situation where the winding ring 104 is separated by force when the automatic tightening device 101 drives the winding ring 104, the textile is positioned and limited by the adjustable liftable guide roller 17, so that the textile is laid flatly in the fixed groove 3. Then the controller 4 controls the automatic winding device 103 to start winding the textile. The automatic tightening device 101 controls the unwinding speed according to the detection of the tension sensor, and cooperates with the automatic winding device 103 to apply constant tension to the textile, so that the textile is in a tensioned state, ensuring that the entire width of the textile is evenly tensioned, and avoiding stretching deformation during cutting; When the textile is stretched and leveled, the cylinder 62 is first started by the controller 4. The cylinder 62 drives the rectangular ring 63 to move in the movable groove 61, so that the cutting groove 64 at the top of the rectangular ring 63 corresponds to the blade of the cutting knife 2 to ensure that the cutting position is accurate. The controller 4 starts the electric push rod 51 to drive the movable plate 52 to move downward. The movable plate 52 drives the ultrasonic generator 54, the transducer 55, the amplitude rod 56 and the cutting knife 2 to move downward together. In this process, the pressure sensor 14 is installed at the bottom of the movable plate 52 and contacts the textile as it moves downward. It detects the pressure of the bottom of the movable plate 52 on the textile when it moves downward in real time and feeds back to the controller 4 to adjust the electric push rod 51 to prepare for subsequent cutting. At the same time, the positioning frame 65 at the bottom of the movable plate 52 moves downward to cooperate with the top of the rectangular ring 63 to align with the cutting knife. 2. The inner and outer sides of the cutting position are limited and fixed. At the same time, the pressing plate 82 in the connecting groove 81 follows the movable plate 52 to move to the top of the sample to be cut, and cooperates with the support plate 83 in the rectangular ring 63 to clamp and further position the textile. The cut sample falls on the support plate 83, providing stable support for the sample. The controller 4 controls the ultrasonic generator 54 according to the detection data of the pressure sensor 14. The ultrasonic generator 54 activates the transducer 55 through the wire. The transducer 55 converts electrical energy into mechanical energy and transmits the ultrasonic energy to the cutting knife 2 through the horn 56, causing the cutting knife 2 to generate high-frequency vibration. The cutting knife 2 cuts the textile fibers through the high-frequency vibration of the ultrasonic energy, thereby achieving high-precision cutting of the textile and obtaining a sample that meets the size and regularity requirements. After cutting, the micro centrifugal fan 71 is started by the controller 4 to generate suction, and the cut debris at the bottom of the concentrating plate 74 is transported to the inside of the filter box 72 through the collection hose 73 for filtration. At the same time, the cleaning head 75 in the connecting groove 53 and the cleaning head 76 in the movable groove 61 synchronously suck the cut debris around them and transport them to the filter box 72 through the pipeline for filtration. The debris is collected in the filter box 72 and the clean air is discharged, realizing real-time adsorption and cleaning of the cut debris, keeping the equipment clean, and preventing the debris from affecting the sample quality and subsequent testing; During the cutting process, the electric push rod 51 drives the compression ring 92 to slide in the air storage column 91 through the connecting rod 93, compressing the gas in the air storage column 91 to store energy. After cutting, the controller 4 can first control the cylinder 62 to reset, and then control the two-way solenoid valve 95 to open. The air storage column 91 is connected to the movable column 94. The compression energy pushes the moving rod 96 and the lowering plate 97 in the movable column 94 to move downward. The lowering column 11 at the bottom of the lowering plate 97 cooperates with the unloading trough 12 at the top of the support plate 83 to push the cut textile sample from the support plate 83 through the unloading trough 12 The sample is sent to the collection box 84 below for collection. During this period, the micro centrifugal fan 71 continues to collect and clean the surface of the cut sample through the concentrating plate 74 and the cleaning head 76 to ensure that the cutting residues on the sample surface are cleaned to avoid affecting the subsequent detection. After the unloading is completed, the controller 4 controls the electric push rod 51 to reset and drive the movable plate 52 to move upward, and at the same time, it can drive the compression ring 92 to move upward. The two-way solenoid valve 95 switches to the reflux mode. The gas in the movable column 94 returns to the gas storage column 91 through the pipeline under the action of the pressure difference, realizing gas recycling. The buffer plate 20 at the bottom of the movable plate 52 is connected to the positioning frame 65 through the damping ring 21, which absorbs vibration energy during the cutting process and reduces the influence of equipment vibration on cutting accuracy. The positioning frame 65 slides in the movable plate 52 to ensure the stability and reliability of the buffering process. The collection box 84 can slide in the fixed groove 3 through the movable groove 18 on the front of the rectangular ring 63, which is convenient for removal. The transparent plate 19 on the front is convenient for observing the sample collection situation so that it can be processed in time. The whole equipment realizes the functions of accurate sampling, debris cleaning, sample collection and the like of textiles through the coordinated work of various components, improves the sampling efficiency and sample quality, and meets the requirements of light resistance, sweat resistance and reproducibility of textiles. In order to meet the requirements of the color fastness test, in actual use, in order to ensure the accuracy of the test, multiple samples will be cut from the same textile. Therefore, after sampling, the textile will continue to be transported under the coordinated work of the automatic tightening device 101 and the automatic winding device 103, and the above operations are repeated to achieve rapid multiple cutting and sampling. The user can preset the cutting quantity through the controller 4. When sampling a large number of different textiles, the textiles can be wound on the surfaces of multiple different removal rings 105 in advance, which can facilitate the rapid replacement of another textile for sampling on the automatic tightening device 101 and the automatic winding device 103 after sampling one textile.
