[0002] The friction detection device after the production of intimate fabrics is usually a device specially used to measure the friction performance of the fabric surface. It continuously rubs the fabric and uses a specific detection method to accurately measure the friction coefficient of the fabric. This device can provide an important basis for the quality control of intimate fabrics, ensure that the produced fabrics meet the requirements in terms of comfort and durability, and guarantee the consumer's user experience.

[0003] In some existing technologies, the detection device adopts a relatively fixed friction mode, and only performs friction tests in a specific moving direction and stroke, such as continuously maintaining the linear movement of the friction head for detection.

Moreover, the fixation of one group of fabrics can be released separately by pressing the limit block. When the detection result of a certain group of fabrics is unqualified, it can be replaced separately, thereby avoiding the problem of having to stop the operation as a whole when replacing the fabric, which affects the detection efficiency of other multiple groups of fabrics.

[0030] like Figures 1 to 8As shown, the present invention provides a friction detection device for after the production of close-fitting fabrics, comprising a base 1, a fixing plate 2 is fixedly connected to the top outer wall of the base 1, a fixing mechanism 4 is arranged on the top outer wall of the base 1, a fabric placement table 5 is fixedly connected to the top outer wall of the base 1, and a friction mechanism 3 is arranged on the outer wall of the fixing plate 2; the friction mechanism 3 comprises a moving block 301, the inner wall of the moving block 301 is rotatably connected to a rotating shaft 302, a friction head 303 is arranged on the bottom outer wall of the rotating shaft 302 through a limiting component, a slot 306 is provided on the outer wall of the rotating shaft 302, and a ring 305 is slidably connected to the outer wall of the rotating shaft 302, The outer wall of the ring 305 is fixedly connected to the plug block 307, the outer wall of the moving block 301 is provided with a slot A308, the outer wall of the fixed plate 2 is fixedly connected to the connecting plate 314, the outer wall of the connecting plate 314 is fixedly connected to the rack 304, the top outer wall of the rotating shaft 302 is rotatably connected to the gear 312, the outer wall of the gear 312 is provided with a slot B315, the outer wall of the fixed plate 2 is slidably connected to the top plate 313, the outer wall of the ring 305 is fixedly connected to the fixed block 309, the inner wall of the fixed block 309 is elastically connected to the pull rod 311 through the connecting spring 310, and the outer wall of the fixed plate 2 is fixedly connected to the electric slide rail 6.

[0031] The above scheme is adopted: the base 1 can be placed on the workbench, and the two ends of the produced close-fitting fabric are fixed by the fixing mechanism 4 to keep the tension, and placed on the fabric placement table 5, and the friction degree of the fabric can be detected by the friction mechanism 3; the fixing mechanism 4 can fix or release multiple groups of fabrics at the same time, and can also fix or release one group of fabrics separately. During the detection process, when a group of fabrics is damaged by friction, it can be removed separately and new fabrics can be placed, that is, there is no need to stop the detection of other fabrics, and the unqualified fabrics can be removed and replaced separately, which improves the detection efficiency; through the friction mechanism 3, it can be adjusted The friction mode of the friction head 303 can not only perform linear friction, but also rotate simultaneously during the linear friction process, so that the fabric is subjected to friction from different directions, simulating the friction that the fabric is subjected to in actual use, and better evaluating the wear resistance and anti-friction performance of the fabric in actual use; the plug block 307 is arranged on the upper and lower sides of the ring 305, and the ring 305 moves downward to enable the plug block 307 to be plugged into the slot A308 so that the friction head 303 moves linearly but cannot rotate. When the ring 305 moves upward, the plug block 307 can be plugged into the slot B315 so that the friction head 303 rotates during the linear movement, thereby better performing friction detection.

[0032] like Figures 2 to 6As shown, the moving block 301 is slidingly connected to the electric slide rail 6, the gear 312 is rotationally connected to the top plate 313, and the plug block 307 is engaged with the slot A308 and the slot B315; the gear 312 is meshed with the rack 304, one end of the connecting spring 310 is fixedly connected to the outer wall of the pull rod 311, and the other end of the connecting spring 310 is fixedly connected to the inner wall of the fixed block 309; the pull rod 311 is slidingly connected to the inner wall of the fixed block 309, and the pull rod 311 is engaged with the slot 306.

[0033] The above scheme is adopted: the electric slide rail 6 is a prior art, fixed on the fixed plates 2 on both sides, and when it is started, it can drive the moving block 301 to move, so that the rotating shaft 302 drives the friction head 303 to move linearly, and the gear 312 is meshed with the rack 304, so that it rotates during the movement; because the rotating shaft 302 is rotatably connected with the gear 312, and the ring 305 is slidably connected to the outer wall of the rotating shaft 302, the ring 305 and the rotating shaft 302 cannot rotate. When the plug block 307 on the ring 305 is plugged into the slot A308, the rotating shaft 302 will not rotate with the gear 312, but drive the friction head 303 to move linearly for friction; when the plug block 307 on the ring 305 is plugged into the slot B315, it is out of contact with the slot A308. In this state, when the moving block 301 moves, the gear 312 can The ring 305 is driven to rotate synchronously with the rotating shaft 302, so that friction detection can be performed while rotating during the linear movement process; when not affected by external forces, the pull rod 311 remains popped out and engaged with a group of slots 306 due to the elastic force of the connecting spring 310. The slots 306 are provided with two groups, the upper and lower groups, and the ring 305 can be fixed at the upper and lower positions. By pulling the pull rod 311 to disengage it from the slots 306, the limit of the ring 305 can be released to move it up and down; during the movement of the moving block 301, the rack 304 is in a fixed state, and the gear 312 moves on its outer wall. The two gear blocks are meshed with each other so that the gear 312 can rotate. The gear 312 and the rack 304 are both prior art. Two groups of connecting plates 314 are fixed at both ends of the gear 312, which have a fixing effect on the gear 312.

[0034] like Figure 5 As shown, the limiting assembly includes two groups of wedge blocks 702, which are elastically connected by telescopic springs 701, and the outer wall of the friction head 303 is provided with a through groove 703; the wedge blocks 702 are slidably connected to the inner wall of the friction head 303, and the two ends of the telescopic spring 701 are respectively fixedly connected to the two groups of wedge blocks 702, and the wedge blocks 702 are clamped in the through groove 703.

[0035] By adopting the above scheme: through the setting of two groups of wedge blocks 702, the friction head 303 can be conveniently and quickly fixed under the rotating shaft 302, the wedge block 702 keeps the arc surface facing upward, and the lower surface contacts the inner wall of the through groove 703. When the friction head 303 contacts the cloth, the wedge block 702 faces the wedge block 702 so that the wedge block 702 will not move upward, and when the friction head 303 needs to be replaced, the friction head 303 can be directly pulled downward to be removed, which is relatively fast and does not require disassembly and installation by turning bolts, etc., saving time and effort.

[0036] like Figure 7 and Figure 8 As shown, the fixing mechanism 4 includes a lower clamping block 406, the inner wall of the fixing plate 2 is elastically connected to the stopper 402 through a reset spring 401, the inner wall of the fixing plate 2 is slidably connected to the connecting rod 403, the inner wall of the base 1 is slidably connected to the trapezoidal block 404, the outer wall of the trapezoidal block 404 is fixedly connected to the shifting block 405, the inner wall of the fixing plate 2 is elastically connected to the moving plate 407 through a compression spring B411, the inner wall of the moving plate 407 is slidably connected to the upper clamping block 408, the inner wall of the upper clamping block 408 is elastically connected to the limiting block 410 through a compression spring A409, and the inner wall of the moving plate 407 is provided with a groove 412.

[0037] The above scheme is adopted: through the contact between the upper clamping block 408 and the lower clamping block 406, the two ends of the cloth between the two can be fixed, so that it maintains a certain tension and is placed on the cloth placing table 5 for friction detection operation; the upper clamping block 408 is provided with multiple groups, corresponding to the position of the protrusions at the top of the lower clamping block 406, and is fixed in the movable plate 407 by the limit block 410. When the movable plate 407 moves, it can drive the multiple groups of upper clamping blocks 408 to move synchronously, so that multiple groups of cloth can be fixed or released at the same time; the limit block 410 includes two upper and lower square blocks, and the lower square block can be engaged with the groove 412 to fix the upper clamping block 408, and The upper square block is always kept outside, and the operator can press the upper square block to release the limit of the upper clamping block 408 and move it to release the fixation of one of the groups of cloth; when the movable plate 407 moves downward, it will squeeze the compression spring B411 and limit it through the blocks 402 in the fixed plates 2 on both sides, so that the upper clamping block 408 maintains its position with the lower clamping block 406; and by toggling the toggle block 405, the trapezoidal block 404 can be driven to move, so that the two groups of blocks 402 are disengaged from the movable plate 407 at the same time, and the limit of the movable plate 407 can be released. Under the elastic force of the compression spring B411, it can be moved upward and reset, and the fixation of multiple groups of cloth can be released.

[0038] like Figure 7 and Figure 8As shown, the lower clamping block 406 is fixedly connected to the top outer wall of the base 1, one end of the return spring 401 is fixedly connected to the outer wall of the stop block 402, the other end of the return spring 401 is fixedly connected to the inner wall of the fixed plate 2, and the stop block 402 is slidably connected to the inner wall of the fixed plate 2; one end of the connecting rod 403 is fixedly connected to the outer wall of the stop block 402, the other end of the connecting rod 403 is slidably connected to the outer wall of the trapezoidal block 404, the limit block 410 is engaged with the groove 412, and the movable plate 407 is slidably connected to the inner wall of the fixed plate 2; one end of the compression spring A409 is fixedly connected to the inner wall of the upper clamping block 408, the other end of the compression spring A409 is fixedly connected to the outer wall of the limit block 410, the limit block 410 is slidably connected to the inner wall of the upper clamping block 408, one end of the compression spring B411 is fixedly connected to the outer wall of the movable plate 407, and the other end of the compression spring B411 is fixedly connected to the inner wall of the fixed plate 2.

[0039] The above scheme is adopted: the arc surface of the stopper 402 is always facing upwards, and when the movable plate 407 moves downward, the arc surface of the stopper 402 is squeezed to make it move toward the inner wall of the fixed plate 2, and at this time, the return spring 401 is forced to shrink, and when the movable plate 407 moves to the bottom of the stopper 402, the return spring 401 causes the stopper 402 to pop out, and its straight surface contacts the outer wall of the movable plate 407 to limit its position, so that multiple groups of fabrics are fixed at the same time through the upper clamping block 408 and the lower clamping block 406; at this time, the connecting rod 403 keeps in contact with the short side inclined surface of the trapezoidal block 404, and when the dial block 405 is turned, the trapezoidal block 404 moves to the long side inclined surface and contacts the connecting rod 403, and the connecting rod 403 drives the stopper 402 to move to both sides, and the movable plate 407 is moved to the bottom of the stopper 402 ... When the plate 407 is out of contact, the limit of the movable plate 407 can be released, and the movable plate 407 moves upward under the elastic force of the compression spring B411, so that the upper clamping block 408 can be disengaged from the lower clamping block 406, and the contact with multiple groups of cloth can be fixed; when the upper clamping block 408 and the lower clamping block 406 are both in contact and fixed state, pressing the square block above the limit block 410 can make it disengage from the groove 412, and contact the limit of a group of upper clamping blocks 408, so that it can be moved upward and disengaged from the lower clamping block 406, and a group of cloth can be fixed alone. Therefore, when a group of cloth fails the inspection and needs to be removed, it is not necessary to stop the inspection of other groups of cloth and can be removed alone, thereby maintaining the inspection efficiency and being more flexible.

[0040] The working principle and use process of the present invention:

[0041] Before the inspection, the operator can place the two ends of the multiple groups of close-fitting fabrics between the upper clamping block 408 and the lower clamping block 406 in the fixing mechanisms 4 on both sides, and then push the movable plate 407 downward. When the movable plate 407 moves downward, the compression spring B411 is forced to shrink and squeeze the arc surface of the stoppers 402 on both sides, so that the stoppers 402 move toward the inner wall of the fixed plate 2, and the return spring 401 is forced to shrink; when the movable plate 407 moves below the stopper 402, the return spring 401 causes the stopper 402 to pop out, and the straight surface of the stopper 402 contacts the outer wall of the movable plate 407, limiting the movable plate 407; at this time, the upper clamping block 408 and the lower clamping block 406 are in close contact with the fabrics, and the two ends of the multiple groups of fabrics are fixed, so that the fabrics maintain a certain tension and are placed on the fabric placement table 5, completing the fabric inspection preparation work.

[0042] When it is necessary to perform linear friction detection, the pull rod 311 can be pulled to disengage it from a group of slots 306 on the outer wall of the rotating shaft 302. After the limit of the ring 305 is released, the ring 305 is moved downward to drive the plug block 307 to move downward so that the plug block 307 is plugged into the slot A308 on the outer wall of the moving block 301. At this time, the rotating shaft 302 will not rotate with the gear 312, but will be fixed to the moving block 301. At this time, the electric slide rail 6 is started, and the electric slide rail 6 drives the moving block 301 to move. Since the gear 312 is meshed with the rack 304, during the movement of the moving block 301, the gear 312 rolls on the rack 304, but since the plug block 307 on the ring 305 is plugged into the slot A308, the rotating shaft 302 and the gear 312 cannot rotate relative to each other, so the moving block 301 can only drive the rotating shaft 302 and the friction head 303 to move linearly, and the linear friction detection of the cloth can be performed.

[0043] When the linear friction test is completed, it is necessary to perform a rotation test during the linear friction process to better simulate the friction of the cloth in actual use, and then pull the pull rod 311 again to disengage it from the card slot 306, and move the collar 305 upward to drive the plug block 307 to move upward, so that the plug block 307 is plugged into the slot B315 on the outer wall of the gear 312, and the plug block 307 is disengaged from the slot A308; start the electric slide rail 6, the moving block 301 moves, and the gear 312 rolls on the rack 304, Since the plug block 307 is plugged into the slot B315, the rotating shaft 302, the collar 305 and the gear 312 are fixed, and the rotating shaft 302 is rotatably connected to the moving block 301. At this time, the gear 312 can drive the collar 305 and the rotating shaft 302 to rotate synchronously, and drive the friction head 303 to rotate during the linear movement. The friction detection of the cloth while the cloth moves linearly and rotates at the same time is performed, so that the cloth is subjected to friction forces from different directions, thereby improving the diversity of detection methods and better evaluating the wear resistance and anti-friction performance of the cloth in actual use.

[0044] During the detection process, if one group of fabrics fails the detection and needs to be removed, the square block above the limit block 410 can be pressed, and the limit block 410 moves inward and disengages from the groove 412 on the inner wall of the movable plate 407, thereby releasing the limit of one group of upper clamping blocks 408. At this time, the upper clamping block 408 can be moved upward to disengage from the lower clamping block 406, and the fixation of one group of fabrics can be released separately, while the fixation of other groups of fabrics is not affected. It is not necessary to stop the detection of other groups of fabrics, and the unqualified fabrics can be removed separately, thereby maintaining the effectiveness of the detection of other groups of fabrics. rate; when multiple groups of fabrics are all qualified and need to be removed at the same time, the dial block 405 can be toggled to drive the trapezoidal block 404 to move, and the trapezoidal block 404 moves to the long side inclined surface to contact the connecting rod 403, and the connecting rod 403 is squeezed to drive the stopper 402 to move to both sides, so that the stopper 402 is out of contact with the moving plate 407, and the limit of the moving plate 407 is released; under the elastic force of the compression spring B411, the moving plate 407 moves upward, driving multiple groups of upper clamping blocks 408 to move upward at the same time, so that the upper clamping block 408 is out of contact with the lower clamping block 406, and the fixation of multiple groups of fabrics can be released at the same time.

[0045] After a long period of testing, the friction head 303 may be worn and need to be replaced; the friction head 303 can be fixed under the rotating shaft 302 by engaging the two sets of wedge blocks 702 with the through slots 703; when the friction head 303 needs to be replaced, the friction head 303 is directly pulled downward, and the through slots 703 squeeze the arc surfaces of the two sets of wedge blocks 702 to move them into the inner wall of the rotating shaft 302, and the friction head 303 can be removed; during installation, it is necessary to first squeeze the two sets of wedge blocks 702 to move them into the inner wall of the rotating shaft 302, and insert the friction head 303 upward under the rotating shaft 302, and when the positions of the wedge blocks 702 and the through slots 703 correspond to each other, they pop out to both sides under the elastic force of the telescopic springs 701 and engage with the through slots 703, and the installation of the friction head 303 is completed, and there is no need to disassemble and install by turning bolts, etc., which saves time and effort.
