At this time, the breathability of the underwear fabrics will change, and the breathability of the underwear fabrics will also change with the amount of sweat. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] An automatic quality detector for seamless underwear fabrics, based on Figure 1-6As shown, the air permeability tester 1 includes an upper chamber 11, a lower chamber 12, and a support frame 2; the air permeability tester 1 integrates an instrument case, a display screen, a servo electric cylinder, a switch knob, etc.; the air permeability tester 1 is connected to an upper chamber 11 via two servo electric cylinders; the instrument case of the air permeability tester 1 is connected to two lower chambers 12; and two support frames 2 are fixed to the upper surface of the instrument case of the air permeability tester 1;

[0036] It also includes a driving mechanism, an electric actuator 203, a fixed ring 204, a tensioning belt 205 and a round roller 206; all support frames 2 are connected to the driving mechanism; the driving mechanism is connected to two electric actuators 203; the driving mechanism is used to drive all electric actuators 203 to move; each telescopic part of the electric actuator 203 is fixedly connected to a fixed ring 204, and the two fixed rings 204 are engaged with each other, and a plurality of rubber strips are provided on the outer side of the rear of the fixed ring 204 to increase the friction between the fixed ring 204 and the underwear grey cloth 3; each fixed ring 204 is slidably connected to the outer side of a tensioning belt 205, and all tensioning belts 205 are made of elastic material; all electric sliders 202 located at the rear are fixedly connected to a round roller 206.

[0037] The driving mechanism includes an electric slide rail 201 and an electric slider 202; each support frame 2 is fixed with an electric slide rail 201; each electric slide rail 201 is slidably connected to two electric sliders 202; the two electric sliders 202 located in the front are each fixed with an electric actuator 203.

[0038] A plurality of rubber strips are provided on the inner side of each tensioning belt 205 to increase the friction between the tensioning belt 205 and the underwear grey fabric 3 .

[0039] An air bag 207 is also included; each round roller 206 is fixedly connected to an air bag 207 .

[0040] When testing the breathability of underwear grey fabric 3: Since the existing fabric breathability testing equipment mostly uses the method of testing pre-processed test samples to obtain the breathability of underwear grey fabric 3 when testing underwear grey fabric 3, it is easy to cause errors in the test results, resulting in inaccurate test results. In order to solve the above problem, the underwear grey fabric 3 is placed in the breathability tester 1. At this time, the lower edge 31 of the underwear grey fabric 3 is sleeved on the rear outer side of the two fixing rings 204, and the two tensioning belts 205 are manually pulled to slide backward along one fixing ring 204, and then the two tensioning belts are stretched. The belt 205 is used to expand the two tensioning belts 205 and position them on the outside of the lower edge 31. The two tensioning belts 205 are then loosened, and the lower edge 31 of the underwear grey fabric 3 is fixedly clamped on the rear outside of the two fixing rings 204 by the two tensioning belts 205. The two shoulder straps 32 of the underwear grey fabric 3 are then manually put on the outside of a round roller 206, thereby limiting the two shoulder straps 32 of the underwear grey fabric 3, and thus achieving fixed clamping of the underwear grey fabric 3. At this time, the two coasters of the underwear grey fabric 3 are each located on a lower cavity 12 and supported by the lower cavity 12. Figure 6 As shown, the air permeability tester 1 is then controlled to operate, and the servo electric cylinder on the air permeability tester 1 is controlled to operate so that the two upper chambers 11 move against each coaster, so that the two coasters of the underwear grey cloth 3 are respectively located between an upper chamber 11 and a lower chamber 12, and are clamped by the upper chamber 11 and the lower chamber 12. Then, the air permeability tester 1 is controlled to continue operating, and the lower chamber 12 is first vacuumed. When the specified vacuum degree is reached, the lower chamber 12 is closed, and the test gas is then filled into the upper chamber 11. At this time, the gas will penetrate from the high-pressure side to the low-pressure side under the action of the pressure gradient. By monitoring the pressure in the low-pressure side, the air permeability parameter of the measured underwear grey cloth 3 is finally obtained. Therefore, the air permeability of the underwear grey cloth 3 is obtained by directly testing the underwear grey cloth 3, which effectively reduces the error of the test result and improves the accuracy of the test result.

[0041] Moreover, due to different body shapes of different people and different sizes and fabric materials of underwear grey cloth 3, when people wear and use underwear grey cloth 3, underwear grey cloth 3 will be stretched to different degrees to fit human skin and improve comfort. After the underwear grey cloth 3 is stretched, the shape of the underwear grey cloth 3 will change, causing the air permeability of the local position of the underwear grey cloth 3 to change. The existing fabric air permeability testing equipment is unable to detect the underwear grey cloth 3 after stretching, resulting in great limitations in air permeability testing. In order to solve the above problem, the two electric sliders 202 in the front are controlled to start and move forward along an electric slide rail 201 respectively. The movement of the two electric sliders 202 drives each electric actuator 203 to move. The movement of the two electric actuators 203 drives each fixed ring 204 to move. The movement of the two fixed rings 204 drives all the tensioning belts 205 to move, and then drives The lower edge 31 of the underwear grey cloth 3 moves, and at the same time, the two electric sliders 202 at the rear are controlled to start and move backward along an electric slide rail 201 respectively. The movement of the two electric sliders 202 drives each round roller 206 to move, and the movement of the two round rollers 206 drives the two shoulder straps 32 of the underwear grey cloth 3 to move. Then, the two electric actuators 203 are controlled to start and drive each fixed ring 204 to move, so that the two fixed rings 204 move away from each other, and then the lower edge 31 of the underwear grey cloth 3 is stretched transversely with the front side of the breathability tester 1 as a reference, thereby stretching the entire underwear grey cloth 3, and then the breathability tester 1 is controlled to operate according to the same working principle as above, and various barrier parameters of the measured underwear grey cloth 3 are obtained, thereby obtaining the breathability of the underwear grey cloth 3 after being stretched, thereby realizing the breathability test of the stretched underwear grey cloth 3, avoiding the problem of large limitations in the breathability test.

[0042] Example 2:

[0043] On the basis of Example 1, according to Figure 7-8As shown, it also includes a cleaning system; each support frame 2 is connected to a cleaning system; the cleaning system includes a fixed plate 301, a fixed rod 302, a DD motor 303, a transmission rod 304, a ring 305, a disc 306 and a guide ring 307; each support frame 2 is fixed with a fixed plate 301; each fixed plate 301 is fixed with a fixed rod 302; each fixed rod 302 is installed with a DD motor 303; each DD motor 303 output shaft is fixed with a transmission rod 304, and the middle part of the transmission rod 304 is a hollow structure, and the hollow structure in the middle of the transmission rod 304 is annularly equidistantly opened with multiple holes. through holes; a circular ring 305 is fixedly connected to the lower end of each transmission rod 304; the transmission rod 304 is communicated with the circular ring 305; a disc 306 is fixedly connected to the lower part of each circular ring 305, and the circular ring 305 is communicated with the circular disc 306, and the circular disc 306 is made of rubber, which is used to fit the underwear grey cloth 3 and adapt to the underwear grey cloth 3 in different stretching states. Sweat is sprayed onto the underwear grey cloth 3 through the circular disc 306, thereby simulating the state of the underwear grey cloth 3 absorbing sweat; a guide ring 307 is rotatably connected to each transmission rod 304, and a joint is fixed to the guide ring 307, and the through hole in the middle of the transmission rod 304 is communicated with the guide ring 307.

[0044] The hollow structure in the middle of the transmission rod 304 is funnel-shaped and is used to guide water.

[0045] A plurality of protrusions are provided on the outside of the disc 306 for increasing the friction between the disc 306 and the underwear grey fabric 3 .

[0046] When the air permeability test is performed on the wet underwear fabric 3: the external pump 402 for water delivery is connected to the joints on the two guide rings 307 in advance. Since people will perform various movements when wearing the underwear fabric 3, some sweat will be absorbed by the underwear fabric 3. At this time, the air permeability of the underwear fabric 3 will change, and the air permeability of the underwear fabric 3 will also change with the amount of sweat. In addition, the underwear fabric 3 will be stretched to different degrees during actual wearing to fit the human skin and improve comfort, causing the underwear fabric 3 to absorb sweat in a stretched state. However, it is difficult for existing testing equipment to perform air permeability testing on the underwear fabric 3 that has absorbed sweat and is stretched. The external pump 402 is controlled to operate to deliver water to the two guide rings 307. For the convenience of description, a disc 306 will be taken as an example below. Water flows along the guide ring 307 into the transmission rod 304 and The water flows toward the disc 306 and is finally sprayed toward the underwear grey fabric 3 through the disc 306, thereby simulating the state of the underwear grey fabric 3 absorbing sweat. Then, the breathability tester 1 is operated to obtain the breathability of the underwear grey fabric 3 absorbing sweat. Moreover, since the hollow structure in the middle of the transmission rod 304 is funnel-shaped and the multiple circular holes opened at the lower part of the disc 306 make the water flow more uniform, thereby improving the accuracy of the test. At this time, the underwear grey fabric 3 is stretched in the same manner as above, so that the underwear grey fabric 3 is tested in the state of being stretched and absorbing sweat, thereby realizing the breathability test of the underwear grey fabric 3 that has absorbed sweat and is stretched. When the underwear grey fabric 3 does not need to be stretched, it only needs to be clamped and limited, thereby simulating various different states of the underwear grey fabric 3 during actual use, thereby further improving the accuracy of the test.

[0047] In addition, since the underwear grey cloth 3 will generate friction with external clothing during wearing, the underwear grey cloth 3 will affect the air permeability of the underwear grey cloth 3 after a long period of friction, the DD motor 303 is controlled to start, and the output shaft of the DD motor 303 rotates to drive the transmission rod 304 to rotate, and the rotation of the transmission rod 304 drives the ring 305 to rotate, and the rotation of the ring 305 drives the disk 306 to rotate, and then the friction between the disk 306 and the underwear grey cloth 3 is simulated to generate friction between the underwear grey cloth 3 and external clothing, and then the air permeability tester 1 is controlled to operate to obtain the air permeability of the underwear grey cloth 3 after friction, thereby realizing the testing of the underwear grey cloth 3 when the underwear grey cloth 3 is stretched, absorbs sweat, and is rubbed.

[0048] Example 3:

[0049] On the basis of the second embodiment, according to Figure 9-10As shown, a drying system is also included; the rear of each fixed ring 204 is connected to the drying system; the drying system includes an air pipe 401, a pump 402 and a conduit 403; an air pipe 401 is fixedly connected to the rear of each fixed ring 204; a pump 402 is fixedly connected to the inner side of each fixed ring 204; the air outlet of each pump 402 is fixedly connected to and connected to a conduit 403, and each conduit 403 passes through a fixed ring 204 and is fixedly connected to and connected to the air pipe 401. When two pumps 402 operate, each transmits air to the corresponding air pipe 401 through a conduit 403, so that the gas is blown toward the underwear grey cloth 3, thereby drying the underwear grey cloth 3.

[0050] It also includes a CCD camera 404; a CCD camera 404 is installed on the rear side of each fixing ring 204, and the two CCD cameras 404 are used to detect the entire underwear fabric 3 from the inner side of the underwear fabric 3, so as to know whether the quality of the underwear fabric 3 meets the production standards.

[0051] When simulating the use of underwear grey cloth 3: Since the underwear grey cloth 3 needs to be washed and aired during daily use, and this cycle repeats, the performance of the underwear grey cloth 3 will gradually decline over time. Then, detergent is sprayed onto the underwear grey cloth 3 through the disc 306 in the same manner as above, and the disc 306 rotates and rubs against the underwear grey cloth 3 again to simulate the cleaning process of the underwear grey cloth 3. After the cleaning is completed, all the electric sliders 202 and the electric actuator 203 are controlled to operate in the manner described above, and then the entire underwear grey cloth 3 is stretched again. After the underwear grey cloth 3 is stretched, the two pumps 402 are controlled to operate, and each of the two pumps 402 supplies air into the corresponding trachea 401 through a conduit 403. The air is blown toward the underwear grey fabric 3, thereby drying the underwear grey fabric 3. The drying process is performed while the underwear grey fabric 3 is stretched, effectively improving the drying efficiency. The condition of the underwear grey fabric 3 in daily use is simulated, and the cleaning and drying processes are repeated many times. Then, the air permeability tester 1 is controlled to operate, thereby obtaining the air permeability of the underwear grey fabric 3 after the repeated cleaning and drying processes, thereby detecting the air permeability of the underwear grey fabric 3 in actual use. After the repeated cleaning and drying processes, the underwear grey fabric 3 is stretched again, thereby detecting the underwear grey fabric 3 in the stretched state after repeated cleaning.

[0052] In addition, since quality problems such as thread breakage, yarn twisting, and stitch defects are prone to occur during the entire production process of the underwear grey cloth 3, and most of these quality problems need to be checked manually piece by piece, long-term manual work can easily fatigue the eyes and cause missed inspections, resulting in unstable inspection quality, missed inspections and false inspections often occurring, thereby affecting the quality of the underwear grey cloth 3. To solve the above problems, after the entire underwear grey cloth 3 is stretched, the two CCD cameras 404 are controlled to operate, and then the entire underwear grey cloth 3 is inspected from the inner side of the underwear grey cloth 3 by the two CCD cameras 404, so as to know whether the quality of the underwear grey cloth 3 meets the production standards, reduce the defective rate, and improve the quality of the underwear grey cloth 3.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
