Description

Technical Field

[0001] The invention belongs to the technical field of textile silk sample quality detection, and in particular relates to a detection technology for solid waste contained in textile silk samples. Background Art

[0002] At present, the quality of textile raw materials is mainly judged by appearance. For bulk textile raw materials at customs ports, such as cotton, cotton linters, waste cotton, asbestos, animal hair fibers, hemp fibers, etc., the accuracy of textile silk sample image acquisition directly affects the classification of sample grades. At present, the conventional sample appearance image acquisition at customs ports only takes pictures of the surface of the sample, which cannot fully reflect the state of the overall solid waste contained in the sample, such as whether there are impurities, dust, foreign fibers and other solid wastes. There is currently no detection method for taking multi-dimensional photos of textile silk samples after spraying them, that is, there is no detection method for capturing images of all substances in the sample and fully reflecting the appearance state of the sample when it is diffused. Summary of the invention

[0003] The purpose of the present invention is to provide a technical identification device which can take multi-dimensional photos after the textile silk sample is sprayed, collect images of all substances in the sample, and comprehensively reflect whether the textile silk sample contains solid waste components.

[0004] The idea of ​​the present invention is to use the method of using air pressure difference to spray the textile silk sample, so as to scatter the textile silk sample, reveal impurities, dust, foreign fibers and other solid wastes in the diffusion space, and use the photos of the textile silk sample in the sprayed state as the detection basis.

[0005] The structure of the present invention is:

[0006] The image collector of the spray state of textile silk samples comprises a high-pressure tank 1, a vacuum pump 2, and an air compressor 3, wherein the characteristics are as follows: the air extraction pipe of the vacuum pump 2 is connected to the high-pressure tank 1, the air outlet pipe of the air compressor 3 passes through the bottom cover 4 of the high-pressure tank 1 and is connected to the high-pressure tank 1, and in the high-pressure tank 1, a sample storage cup 5 is connected to the air outlet of the air outlet pipe of the air compressor 3, and the air outlet of the air outlet pipe of the air compressor 3 and the sample storage cup 5 are separated by a high-pressure resistant steel wire mesh 6; an in-pipe air pressure sensor 13 is arranged in the air outlet pipe of the air compressor 3;

[0007] There is no explosion valve 7 in the high-pressure tank 1. The shell of the explosion valve 7 is connected to the inner wall of the high-pressure tank 1 through a connecting porch 8 to fix its position, and the explosion valve 7 is fixed in the high-pressure tank 1. The valve stem 9 of the explosion valve 7 extends out of the shell of the high-pressure tank 1, and the valve stem 9 is connected to the switch valve motor 10 outside the shell of the high-pressure tank 1; a short tube 11 for connecting a sample cup is provided under the shell of the explosion valve 7, and the short tube 11 for connecting a sample cup is communicated with the inner valve vent 12 of the explosion valve 7, and the short tube 11 for connecting a sample cup is sleeved on the outside of the sample storage cup 5; a plurality of short barbed rods 18 are provided on the inner wall of the inner valve vent 12;

[0008] The high-pressure tank 1 is provided with an in-tank air pressure sensor 14 , an in-tank lighting lamp 15 and a video camera 16 .

[0009] The specific operation of spraying textile silk samples for shooting is as follows: first open the bottom cover 4 of the high-pressure tank 1, put the textile silk sample to be tested into the sample storage cup 5, because the sample storage cup 5 and the air outlet pipe of the air compressor 3 are separated by a high-pressure steel wire mesh 6, the textile silk sample will not fall into the air inlet pipe of the air compressor 3. Put a sealing gasket on the mouth of the sample storage cup 5 containing the textile silk sample, and then align the sample storage cup 5 containing the textile silk sample with the inner space of the short tube 11 of the sample cup, seal the bottom cover 4 of the high-pressure tank 1, and connect the air inlet pipe of the sample storage cup 5 with the air inlet pipe of the air compressor 3, set the explosion valve 7 in a closed state, so that the textile silk sample will not be sucked into the high-pressure tank 1 during vacuuming, and wait for the vacuum pump 2 to start vacuuming.

[0010] The vacuum machine 2 is started and the vacuum is exhausted until the air pressure sensor 14 inside the tank indicates 300 kPa to 500 kPa outside the tank, and then the vacuum machine 2 is stopped.

[0011] Start the air compressor 3. When the air pressure sensor 13 in the pipe shows 3Mpa to 5Mpa outside the pipe, turn the explosion valve 7 to connect the sample storage cup 5 with the air in the high-pressure tank 1 through the inner valve vent 12 of the explosion valve 7. Rapidly flush the 3Mpa to 5Mpa high-pressure gas with the textile sample into the vacuum-evacuated high-pressure tank 1. The pressure difference rapidly increases the explosion force to spray the textile sample in the high-pressure tank 1. At this time, quickly turn on the lighting 15 in the tank, and start the camera 16 to take photos and videos of the textile sample in the spraying state in the high-pressure tank 1. The photography and video recording is the basis for checking whether the textile sample has impurities, dust, foreign fibers and other solid wastes.

[0012] The barbed short rod 18 is provided with small barb protrusions, the purpose of which is to further disperse the ejected textile silk sample and reveal solid wastes such as impurities, dust, foreign fibers, etc.

[0013] The explosion valve 7 is closed to prevent the textile silk sample from being drawn into the high-pressure tank 1 during vacuuming. When the vacuuming stops, the closed explosion valve 7 can allow the air compressor 3 to generate high pressure on the textile silk sample in the sample storage cup 5, so that there is a large pressure difference between the high-pressure tank 1 and the sample storage cup 5. After the large pressure difference, the explosion valve 7 is quickly opened to release the textile silk sample in the high-pressure tank 1 in the vacuum state. The textile silk sample is quickly pushed into the high-pressure tank 1 by the large pressure difference to produce an explosion effect. The explosion force sprays and separates the textile silk from solid wastes such as impurities, dust, and foreign fibers, so that the camera 16 can capture the image of the textile silk separated from solid wastes such as impurities, dust, and foreign fibers, and the image is used as the basis for detecting the presence of solid wastes such as impurities, dust, and foreign fibers in the textile silk sample. The vacuum pump 2 is evacuated to 300kpa ~ 500kpa and the air compressor 3 is pressurized to 3Mpa ~ 5Mpa based on the experimental values ​​that the general textile yarn and the solid waste contained therein can be effectively separated and there is enough floating time. As long as it is within the normal working range of the high-pressure tank 1, it can be selected according to the difference between the textile yarn and the solid waste contained therein.

[0014] In order to accurately control vacuuming, compressor high pressure, opening of the explosion valve 7, real-time shooting, etc., a controller can be used for operation: for example, a controller 17 is also included, and the controller 17 is respectively connected to the vacuum machine 2, the air compressor 3, the switch valve motor 10, the air pressure sensor in the pipe 13, the air pressure sensor in the tank 14, the lighting lamp in the tank 15 and the camera 16.

[0015] The advantages of the present invention are as follows: the device can be used to first evacuate the high-pressure tank and then inject high-pressure gas into the high-pressure tank. A greater pressure difference can be generated in a high-pressure tank with a relatively low pressure resistance, which has a better spraying effect on the textile silk sample placed in the sample storage cup, so that the textile silk and solid wastes such as impurities, dust, and foreign fibers can be fully separated. Then, the camera in the high-pressure tank can better capture solid wastes such as impurities, dust, and foreign fibers, providing sufficient basis for detecting sample quality and grading.
