It is commonly used in the manufacture of clothing and fabrics that require high protection capabilities. The finished products of aramid fiber include clothing, fabrics, gloves, etc. Aramid fiber clothing can not only provide high-level protection, but also has high durability, effectively preventing tearing and puncturing. Aramid fiber has good tolerance to many chemicals and is not easily corroded and degraded by chemicals. Therefore, aramid fiber clothing is suitable for use in chemical processing and manufacturing industries.

It includes a workbench, a placement groove is opened in the middle of the upper end of the workbench, a dry ice release component is arranged on the inner wall of the placement groove, a fabric pressing mechanism is arranged on the workbench, and the fabric pressing mechanism is arranged above the dry ice release component. The fabric pressing mechanism includes an L-shaped plate connected to the workbench, a contact strip is connected to the inner wall of the upper end of the L-shaped plate, a motor is connected to the outer end of the contact strip, the output end of the motor is connected to a rotating rod, two symmetrical threaded grooves are opened on the outer peripheral side of the rotating rod, the rotating rod is threadedly connected with a slider, the lower end of the slider is connected with a C-shaped plate, the lower end of the C-shaped plate is connected with two symmetrical electric push rods, and the output end of the electric push rod is connected with a pressing plate. This utility model realizes the operation of gas permeability detection for gas permeable fabrics of different sizes, improving the applicability of the device.

[0004] However, this device still has the following defects: Although the operation of clicking can drive the two C-shaped plates to move, so that the pressing plate can press different sizes of fabrics and reduce the situation of deviation during gas permeability detection, the size of the pressing plate is limited, and the range that can be pressed and restricted by the fabric is effective, and it is not easy to change the range of pressing and limiting the fabric. This causes some dry ice to leak from the un-pressed position between the clothing and the workbench when the dry ice release device releases dry ice, thus affecting the detection of the detection results by the staff, and when more dry ice leaks, it will also affect the vision of the staff.

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] The embodiments of the present utility model provide a breathability detection device for aramid fiber finished products, including a workbench 1. Exemplarily, as Figures 1-6 shown, a fixing frame 2 is fixedly connected to the upper side of the workbench 1, a fan 31 is fixedly connected to the upper side of the fixing frame 2, one end of the fan 31 penetrates through the fixing frame 2, a fixing block 32 is fixedly connected to the lower side of the fixing frame 2, and the fixing block 32 is arranged outside one end of the fan 31.

[0028] The pressing mechanism 5 includes a pressing hollow block 51 arranged on the upper side of the workbench 1, and a pressing plate 52 is slidably connected to the inner side of the pressing hollow block 51. A card slot 531 is provided on one side of the pressing hollow block 51, and there are multiple card slots 531. A second installation slot 532 is provided on one side of the pressing plate 52.

[0029] A first spring 54 is provided on the inner side of the second mounting groove 532, and one end of the first spring 54 is fixedly connected to the holding plate 52, and the other end of the holding plate 52 is fixedly connected to a spring buckle 55, and the spring buckle 55 is movably connected to the inner side of one of the slots 531. A first electromagnet 56 is provided on the inner side of the first mounting groove 4, and a second electromagnet 59 is provided on the upper side of the first electromagnet 56. One side of the first electromagnet 56 and the second electromagnet 59 are both fixedly connected to a fixing plate 57, and a second spring 58 is fixedly connected between the two fixing plates 57.

[0030] Specifically, the sliding connection between the holding hollow block 51 and the holding plate 52, as well as the cooperation between the clamping slot 531 and the spring catch 55, ensures that the workpiece can be firmly fixed during operation, thereby improving the stability of the processing process;

[0031] In addition, the design of multiple slots 531 allows the spring buckle 55 to cooperate with the slots 531 at different positions, thereby realizing the rapid adjustment of the position of the holding plate 52 and meeting the fixing requirements of garments of different sizes.

[0032] In addition, the first electromagnet 56 and the second electromagnet 59 can press and hold the finished garment through magnetic attraction. At the same time, the second electromagnet 59 can be reset by the second spring 58 when not in use. The gas flow sensor 34 arranged in the hollow groove 33 can monitor the changes in airflow in real time, and combined with the work of the fan 31, the air permeability of the aramid fiber finished garment can be detected.

[0033] The first adjustment mechanism 6 includes a dual-axis motor 61 fixedly connected to the inner side of the fixed block 32, and the output end of the dual-axis motor 61 is connected to the first screw 62 through a coupling. Figures 2-6 shown.

[0034] One side of the fixed block 32 is fixedly connected to a limiting rod 63, and the outer side of the limiting rod 63 is slidably connected to a moving block 64, and the moving block 64 is threadedly connected to the outer side of the first screw 62. The lower side of the moving block 64 is fixedly connected to an electric telescopic rod 65, and the lower end of the electric telescopic rod 65 is fixedly connected to the pressing hollow block 51.

[0035] The second adjusting mechanism 7 includes a servo motor 71 arranged inside the first installation groove 4. The output end of the servo motor 71 is connected to a second screw rod 72 through a coupling. A moving plate 73 is threadedly connected to the outside of the second screw rod 72. The moving plate 73 is slidably connected inside the first installation groove 4. The moving plate 73 is fixedly connected to the lower side of the first electromagnet 56.

[0036] A limiting plate 101 is fixedly connected inside the pressing hollow block 51. A limiting groove 102 is formed on the outside of the pressing plate 52. The limiting plate 101 is slidably connected inside the limiting groove 102.

[0037] Specifically, when the dual-axis motor 61 operates, it can drive the first screw rod 62 to rotate. At the same time, through the connection between the moving block 64 and the limiting rod 63, it drives the moving block 64 and the electric telescopic rod 65 to move, so that the pressing plate 52 and the pressing hollow block 51 can adapt to finished clothing of different sizes. At the same time, the electric telescopic rod 65 can drive the pressing hollow block 51 and the pressing plate 52 to move downward, enabling them to smoothly press the finished clothing.

[0038] In addition, the operation of the servo motor 71 can drive the moving plate 73 to move, so that the moving plate 73 can drive the first electromagnet 56 and the second electromagnet 59 to move together, so that the first electromagnet 56 and the second electromagnet 59 can also adapt to aramid-limited finished products of different sizes. And after the first electromagnet 56 and the second electromagnet 59 are energized, their mutual magnetism can further increase the stability of the finished product during detection.

[0039] In addition, the limiting plate 101 can play a certain limiting role on the pressing plate 52 through the limiting groove 102, which can not only increase the stability of the pressing plate 52 during sliding, but also prevent the pressing plate 52 from slipping out and falling from the inside of the pressing hollow block 51.

[0040] A fixing rod 8 is arranged inside the first installation groove 4. The fixing rod 8 is fixedly connected to the inside of the workbench 1. The moving plate 73 is slidably connected to the outside of the workbench 1, as Figures 1-6 shown.

[0041] A limiting rod 9 is fixedly connected to the upper side of the lower fixing plate 57. The upper end of the limiting rod 9 penetrates through the upper fixing plate 57. The limiting rod 9 is arranged inside the second spring 58.

[0042] A first rubber layer 111 is adhesively bonded to the lower side of the pressing hollow block 51. A second rubber layer 112 is adhesively bonded to the lower side of the pressing plate 52.

[0043] Specifically, the fixed rod 8 can further increase the stability of the moving plate 73 during movement by the rotation of the second screw rod 72. The limiting rod 9 can not only limit the fixing plate 57 on one side of the second electromagnet 59, enabling the second electromagnet 59 to move up and down smoothly, but also limit the expansion and contraction of the second spring 58, making it less likely to deform during expansion and contraction.

[0044] In addition, the first rubber layer 111 and the second rubber layer 112 can increase the stability of the pressing hollow block 51 and the pressing plate 52 when pressing the aramid fiber finished product, and reduce the gap between the aramid fiber finished product and the pressing hollow block 51 and the pressing plate 52, making the clamping effect better.

[0045] Using a breathability detection device for aramid fiber finished products proposed by an embodiment of the present utility model, its working principle is as follows: When this device is in use, the staff can adjust the positions of the pressing hollow block 51 and the first electromagnet 56 according to the size of the aramid fiber finished product clothing. During adjustment, the operation of the servo motor 71 can drive the first electromagnet 56 to move, and the operation of the biaxial motor 61 can drive the electric telescopic rod 65 and the pressing hollow block 51 to move. At the same time, by pressing the snap button 55, the snap button 55 can be moved to the inside of the second installation groove 532, and by moving the pressing plate 52, the pressing plate 52 can be snapped into the internal card slot 531 at other positions through the snap button 55, thus realizing the adjustment of the position of the pressing plate 52, enabling the pressing hollow block 51 and the pressing plate 52 to more smoothly adapt to clothing of different sizes. When the positions of the pressing hollow block 51 and the first electromagnet 56 match the size of the finished product clothing, the staff can place both sides of the finished product clothing on the upper side of the first electromagnet 56, and then energize the first electromagnet 56 and the second electromagnet 59. At this time, the first electromagnet 56 will be magnetically attracted to the second electromagnet 59, sucking the second electromagnet 59 downward. When the second electromagnet 59 is attracted to the first electromagnet 56, it can realize the limiting and clamping of both sides of the clothing.

[0046] At the same time, the electric telescopic rod 65 can also be started. When the electric telescopic rod 65 is operating, it can also drive the pressing hollow block 51 and the pressing plate 52 to move downward. When the pressing hollow block 51 and the pressing plate 52 move downward by a certain distance, it can realize the pressing of the other two sides of the clothing, thereby realizing the large-range limiting and pressing of the clothing and reducing the range of air leakage. Then, the blower 31 can be started to blow air to the finished product clothing through the blower 31, and then the gas flow sensor 34 can be used to detect the air permeability of the finished product clothing.

[0047] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
