Description

Technical Field

[0001] The present invention relates to the technical field of clothing detection, in particular to a school uniform wear resistance strength inspection mechanism. Background Art

[0002] During the processing of school uniform fabrics, it is necessary to test the wear resistance of the fabric and whether it is fuzzing. The conventional inspection method is to use a motor to drive a brush roller to rotate on the fabric and rub it. However, in actual use, it is not convenient to fix the school uniform, which makes it inconvenient to test the wear resistance of the school uniform. The operation is relatively cumbersome. In order to facilitate the fixation of the school uniform, the existing Chinese patent document CN202122621070.7 discloses a school uniform wear resistance inspection mechanism, including an operating table, a support frame is fixedly connected to the operating table, and the support frame is U-shaped, and the inner wall surfaces on both sides of the opposite sides of the support frame are opened A slide groove is provided, and a connecting rod is provided above the operating table, and the end of the connecting rod is fixedly connected to the support plate. The utility model rotates the screw by turning the handle, and the rotation of the screw drives the limiting ring to rotate. The limiting ring rotates in the annular groove and does not cause the connecting rod to rotate with the screw. Since the screw is threadedly connected to the support frame, the screw will move, and the movement of the screw will drive the connecting rod to move, and the movement of the connecting rod will drive the two pressing plates to move. The two pressing plates will fix the two sides of the school uniform, avoiding the position deviation of the school uniform, facilitating the detection of the school uniform, and being more convenient to operate. Although the inspection mechanism of the above-mentioned patent can fix the two sides of the school uniform during testing, since the mechanism only presses and fixes the two sides of the school uniform, the friction position of the school uniform to be tested does not have a certain tensioning effect. Therefore, when the testing piece moves back and forth to rub the surface of the school uniform, the school uniform to be tested will move with the testing piece, which will cause the test results to be inaccurate.

[0018] 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.

[0019] Example 1: Please refer to Figure 1 and Figure 2The figure shows a school uniform wear resistance inspection mechanism, including a testing platform 1, the bottom of which is fixedly connected to a base 2 by four connecting columns; it also includes: a mounting plate 3 fixed on one side of the testing platform 1, and a lifting unit 4 is provided on the side of the mounting plate 3 away from the testing platform 1; a friction unit 5 for testing the wear resistance of the school uniform to be tested is provided directly above the testing platform 1; an upper support unit 6 for tensioning the school uniform to be tested is provided at the very center of the testing platform 1; clamping units 7 are installed at the four corners of the testing platform 1, and the clamping unit 7 is used to fix the school uniform to be tested. A linkage unit 8 for synchronously driving the upper support unit 6 and the clamping unit 7 is also installed at the bottom of the testing platform 1.

[0020] In this solution, the designed lifting unit 4 drives the friction unit 5 to move downward and contact the middle position of the upper side of the school uniform to be tested. At the same time, the lifting unit 4 will also drive the upper support unit 6 and the clamping unit 7 to work in conjunction through the linkage unit 8, wherein the clamping unit 7 is pressed and positioned at the four corners of the school uniform to be tested. While positioning, the upper support unit 6 is synchronously moved upward to tension the middle position of the school uniform to be tested, so that the friction unit 5 will not follow the movement when contacting the school uniform for testing. Then the friction unit 5 is started to work, and the back and forth movement of the output end of the friction unit 5 will rub the surface of the school uniform to test the wear resistance of the school uniform.

[0021] For further information, see Figure 3 The upper support unit 6 includes an annular supporting plate 61, a first connecting plate 62, a first screw rod 63 and a first threaded tube 64. Four first connecting plates 62 distributed in an annular array are fixedly connected to the top of the annular supporting plate 61. The first screw rod 63 is fixedly connected to the annular supporting plate 61 through the first connecting plate 62. The first threaded tube 64 is threadedly connected to the first screw rod 63. A through hole is opened on the detection platform 1. The first threaded tube 64 is rotatably connected to the through hole through a bearing. The first threaded tube 64 is transmission connected to the clamping unit 7 through the linkage unit 8.

[0022] Specifically, the output end in one direction of the linkage unit 8 will drive the first threaded tube 64 to rotate. Since the four groups of first threaded tubes 64 will rotate together under the drive of the linkage unit 8, the four first screw rods 63 will move upward together, thereby stretching the school uniform fabric placed on the annular supporting plate 61 upward. Before the tightening effect is maximized, the clamping unit 7 will press the school uniform fabric on the testing table 1, which is conducive to more stable support.

[0023] For further information, see Figure 4The pressing unit 7 includes a second connecting plate 71, a second screw rod 72, a second threaded tube 73, a piercing piece 74 and an adjusting piece 75. The second connecting plate 71 is fixed to the top of the second screw rod 72, the second threaded tube 73 is threadedly connected to the second screw rod 72, the thread rotation directions of the first screw rod 63 and the second screw rod 72 are opposite, the second threaded tube 73 is rotatably connected to the detection platform 1 through a bearing, the piercing piece 74 is slidably connected to one end of the second connecting plate 71, and the adjusting piece 75 is installed on the top of the second connecting plate 71.

[0024] Specifically, the output end in the other direction of the linkage unit 8 will also drive the second threaded tube 73 to rotate. Since the threads of the first screw rod 63 and the second screw rod 72 are in opposite directions, the first screw rod 63 drives the annular supporting plate 61 to move upward while the second screw rod 72 drives the second connecting plate 71 to move downward, and at the same time drives the piercing member 74 to move downward. The piercing member 74 has a certain sharp length and will pierce a small hole when it contacts the school uniform fabric. Finally, the four corners of the school uniform fabric will be restricted on the test table 1, and there will be no left and right pulling when the fabric is supported and tensioned.

[0025] For further information, see Figure 5 The linkage unit 8 includes a first ring gear 81, a first gear 82, a second ring gear 83, a second gear 84 and a third gear 85. The first ring gear 81 and the second ring gear 83 are both rotatably connected to the bottom of the detection platform 1 through a slewing support, and the first ring gear 81 and the second ring gear 83 are coaxially distributed. The first gear 82, the second gear 84 and the third gear 85 are all provided with four groups. The four groups of first gears 82 are all meshed with the first ring gear 81, the first threaded tube 64 is fixedly sleeved with the first gear 82, and the four groups of second gears 84 are all meshed and connected with the second ring gear 83. One end of the central axis of the second gear 84 is rotatably connected to the detection platform 1 through a bearing, the third gear 85 is meshed and connected with the second gear 84, and the third gear 85 is fixedly sleeved with the second threaded tube 73. A synchronous belt structure is provided for transmission connection between one of the first threaded tubes 64 and one of the second threaded tubes 73.

[0026] Specifically, the power transmitted from the bottom of the lifting unit 4 drives one of the first threaded tubes 64 to rotate, and the first threaded tube 64 drives one of the first gears 82 to rotate, thereby driving the first ring gear 81 to rotate, and the first ring gear 81 drives all the first threaded tubes 64 to rotate synchronously, and finally all the first screw rods 63 rotate at the same time. At the same time, since a synchronous belt structure is provided between the first threaded tube 64 and the second threaded tube 73, and the synchronous belt structure is mainly composed of a pulley and a synchronous belt, when one of the first threaded tubes 64 rotates, it will also drive one of the third gears 85 to rotate, and the third gear 85 will also drive the second gear 84 to rotate, and then drive the second ring gear 83 to rotate, further driving all the second threaded tubes 73 to rotate synchronously, so that all the second screw rods 72 rotate at the same time, so that the annular supporting plate 61 and the second connecting plate 71 move together to ensure that the expansion and compression actions are synchronized.

[0027] For further information, see Figure 6 and Figure 8 The lifting unit 4 includes a lifting motor 41, a ball screw 42, a lifting block 43 and a linkage shaft 44. The lifting motor 41 is fixed to the top of the mounting plate 3. The ball screw 42 is fixedly connected to the output end of the lifting motor 41 through a coupling. The lifting block 43 is threadedly sleeved with the ball screw 42 through a ball nut. Both sides of the ball screw 42 are rotatably connected to the mounting plate 3 through a bearing seat. The linkage shaft 44 is fixed to the bottom end of the ball screw 42. A synchronous belt structure is connected between the linkage shaft 44 and one of the first threaded tubes 64. A first slider 45 is fixed to one end of the lifting block 43. The first slider 45 is slidably connected to the slide groove opened on the mounting plate 3. One end of the friction unit 5 is fixedly connected to the first slider 45.

[0028] Specifically, by starting the lifting motor 41 to rotate, the lifting motor 41 drives the ball screw 42 to rotate, and the ball screw 42 drives the lifting block 43 to move downward, thereby driving the friction unit 5 to move downward until the friction unit 5 contacts the surface of the school uniform fabric to be tested. At the same time, the ball screw 42 will also drive the linkage shaft 44 to rotate, and the linkage shaft 44 drives one of the first threaded tubes 64 to rotate through the synchronous belt structure, and finally drives the linkage unit 8 to work together to ensure the synchronization of the pressing, supporting and lifting actions.

[0029] For further information, see Figure 6The friction unit 5 includes a lifting plate 51, a servo motor 52, a crank 53, a connecting rod 54, a second slider 55 and a friction block 56. The servo motor 52 is fixed on the lifting plate 51, one end of the lifting plate 51 is fixedly connected to the first slider 45, the crank 53 is fixed to the output end of the servo motor 52, the connecting rod 54 is rotatably connected to the end of the crank 53 away from the servo motor 52, the end of the connecting rod 54 away from the crank 53 is rotatably connected to the second slider 55, the second slider 55 is slidably connected to the slide groove provided on the lifting plate 51, the friction block 56 is fixed to the bottom of the second slider 55, and cleaning components 57 for cleaning the bottom end surface of the friction block 56 are provided on both sides of the lifting plate 51.

[0030] Specifically, after the bottom surface of the friction block 56 contacts the school uniform fabric to be tested, the servo motor 52 is started, the servo motor 52 drives the crank 53 to rotate, and the crank 53 drives the connecting rod 54 to rotate, thereby driving the second slider 55 to reciprocate, and allowing the bottom surface of the friction block 56 to rub back and forth on the surface of the school uniform fabric to test the wear resistance of the school uniform.

[0031] This program is a process for testing the abrasion resistance of school uniform fabrics; First, the personnel puts the school uniform fabric to be tested on the testing table 1 and presses both sides of the school uniform fabric with both hands, and then starts the lifting motor 41. The lifting motor 41 drives the friction block 56 to move down through the rotation of the ball screw 42. At the same time, the rotation of the linkage shaft 44 will also drive the linkage unit 8 to work, so that the four first threaded tubes 64 and the four second threaded tubes 73 rotate synchronously, and let the four first screw rods 63 move up and the four second screw rods 72 move down. The first screw rod 63 will drive the annular supporting plate 61 to move up to support the school uniform fabric, and the second screw rod 72 will drive the second connecting plate 71 and the piercing piece 74 to move down, among which the piercing piece 74 will contact the school uniform fabric before the friction block 56. The piercing piece 74 will pierce a small hole when it contacts the school uniform fabric, and the piercing piece 74 will continue to move down to push the four The four corners of the clothing fabric are restricted on the testing platform 1, and the friction block 56 continues to move down, and the annular supporting plate 61 continues to move up. When the friction block 56 contacts the clothing fabric, the annular supporting plate 61 just moves the fabric up and tightens it. Because the four corners of the clothing fabric have been fixed on the testing platform 1 before tightening the clothing fabric, the upward thrust toward the center of the clothing will not cause the two sides of the clothing fabric to be pulled in a larger range, that is, there will be a certain pulling force on both sides of the clothing to better tighten it. After tightening the clothing fabric, the servo motor 52 is started again, and the servo motor 52 drives the crank 53 to rotate, and the crank 53 drives the connecting rod 54 to rotate, thereby driving the second slider 55 to reciprocate, and allowing the bottom surface of the friction block 56 to rub back and forth on the surface of the school uniform fabric to perform wear resistance strength testing on the school uniform.

[0032] Example 2: Please refer to Figure 4 and Figure 7 This embodiment further explains the first embodiment, and the difference lies in that the working position of the piercing member 74 is optimized.

[0033] Specifically, the piercing member 74 includes a movable plate 741, a piercing needle 742, a first fixed block 743, a first sliding rod 744, a second fixed block 745 and an L-shaped plate 746. The piercing needle 742 is fixed to the bottom end of the movable plate 741, the first fixed block 743 is fixed to both sides of the movable plate 741, the first sliding rod 744 is fixed to one end of the first fixed block 743, the second fixed block 745 is fixed to both sides of the second connecting plate 71, the first sliding rod 744 is slidably engaged with the second fixed block 745, the L-shaped plate 746 is fixed to the top of the movable plate 741, a slot 747 adapted to the piercing needle 742 is opened on the detection table 1, and the output end of the adjustment member 75 is fixedly connected to the L-shaped plate 746; At the same time, the adjusting member 75 includes a support plate 751, a third threaded cylinder 752, a third screw rod 753, a limit block 754, an active bevel gear 755, a driven bevel gear 756, a third rotating shaft 757 and a sixth gear 758. The support plate 751 is fixedly connected to the second connecting plate 71 through a fixing rod, and both ends of the third threaded cylinder 752 are rotatably connected to the limit block 754 through bearings. The bottom of the limit block 754 is fixed on the support plate 751, the third screw rod 753 is threadedly connected to the third threaded cylinder 752, the active bevel gear 755 and the driven bevel gear 756 are connected. The movable bevel gear 756 is meshed, and the driven bevel gear 756 is fixedly sleeved with the third threaded cylinder 752. The third rotating shaft 757 is rotatably connected to the support plate 751 through a bearing. The active bevel gear 755 and the sixth gear 758 are respectively fixed on the top and bottom of the third rotating shaft 757. The bottom of the support plate 751 is slidably connected to the limiting ring 759. The bottom of the limiting ring 759 is fixed with a driving ring plate 7510. The outer side of the driving ring plate 7510 is evenly distributed with teeth and grooves. The sixth gear 758 is meshed and connected with the driving ring plate 7510 through the teeth and grooves.

[0034] Specifically, since the sizes of school uniform fabrics are different, the positions of the piercing members 74 at the corners of the school uniform fabrics are also different. In order to adapt to the compression of school uniform fabrics of different sizes, the personnel can adjust the piercing members 74 according to the corners of the school uniform fabrics. When adjusting, the driving ring plate 7510 is rotated by hand, so that the tooth grooves on the driving ring plate 7510 and the sixth gear 758 are engaged and driven, thereby driving the four groups of sixth gears 758 to rotate at the same time, and the sixth gear 758 drives the third shaft 757 to rotate, and the third shaft 75 7 drives the active bevel gear 755 to rotate, the active bevel gear 755 drives the driven bevel gear 756 to rotate, the driven bevel gear 756 drives the third threaded cylinder 752 to rotate, the third threaded cylinder 752 drives the third screw rod 753 to move, thereby pushing the L-shaped plate 746 to move, and the L-shaped plate 746 drives the movable plate 741 to move, so that the horizontal position of the needle 742 can be adjusted to meet the insertion positioning function of school uniform fabrics of different sizes, so that when testing the wear resistance of school uniforms, school uniforms of various specifications can be stably limited, and the operation is flexible and convenient.

[0035] Example 3: Please refer to Figure 6 and Figure 8 This embodiment further illustrates other embodiments, the difference being that the bottom surface of the friction block 56 is optimized.

[0036] Specifically, the cleaning assembly 57 includes a cleaning brush 571, a horizontal rack 572, a fourth gear 573, a first rotating shaft 574, a fifth gear 575, a second rotating shaft 576 and a vertical rack 577. Both ends of the cleaning brush 571 are fixed with horizontal racks 572 by bolts. The upper side of the cleaning brush 571 is provided with a brush surface, and the brush surface is arranged flush with the bottom end surface of the friction block 56. The horizontal rack 572 is meshed with the fourth gear 573. The first rotating shaft 574 and the second rotating shaft 576 are both rotatably connected to the outer side of the lifting plate 51. The fourth gear 573 is fixedly sleeved on the outer side of the first rotating shaft 574. A synchronous belt structure is provided between the second rotating shaft 576 and the first rotating shaft 574. The fifth gear 575 is fixedly sleeved on the outer side of the second rotating shaft 576. One side of the vertical rack 577 Two U-shaped plates 578 are fixed, and the vertical rack 577 is fixedly connected to the mounting plate 3 through the U-shaped plate 578. The fifth gear 575 is meshed with the vertical rack 577, and the end of the horizontal rack 572 away from the cleaning brush 571 is connected with an elastic member 579; the elastic member 579 includes a second slide bar 5791, a third fixed block 5792, a Z-shaped plate 5793 and a return spring 5794, the second slide bar 5791 is fixedly connected to the end of the horizontal rack 572 away from the cleaning brush 571, the second slide bar 5791 and the third fixed block 5792 are slidably sleeved, one side of the third fixed block 5792 is fixedly connected to the lifting block 43 through the Z-shaped plate 5793, one end of the return spring 5794 is fixed to the third fixed block 5792, and the other end is fixed to the outer side of the second slide bar 5791.

[0037] Specifically, when the lifting plate 51 moves downward, it will drive the fifth gear 575 to move downward, and the fifth gear 575 and the fixed vertical rack 577 will trigger the meshing transmission, thereby driving the fifth gear 575 to rotate counterclockwise, and the fifth gear 575 drives the fourth gear 573 to rotate counterclockwise through the synchronous belt structure. At this time, since the horizontal rack 572 is in the state where the last tooth is meshed with the fourth gear 573, the horizontal rack 572 does not perform translational motion, that is, the cleaning brush 571 does not perform cleaning action when the lifting plate 51 moves downward. When the fifth gear 575 moves downward and disengages from the vertical rack 577, the friction block 56 continues to move downward for a distance until it contacts the clothing fabric. After the friction motion ends, the bottom surface of the friction block 56 will absorb a large amount of fine debris falling from the clothing fabric. At this time, the lifting plate 51 moves up to the fifth gear 575 When meshing with the vertical rack 577, it will drive the fifth gear 575 to rotate clockwise, and the fifth gear 575 drives the fourth gear 573 to rotate clockwise through the synchronous belt structure, thereby driving the horizontal rack 572 to move toward the friction block 56 and pushing the cleaning brush 571 to move close to the friction block 56, so that the brush surface of the cleaning brush 571 contacts the bottom surface of the friction block 56, and automatically cleans the small debris adsorbed on the bottom surface of the friction block 56, preventing the small debris from affecting the detection effect when the friction block 56 performs friction movement next time; when the lifting plate 51 moves to the top, the fifth gear 575 and the vertical rack 577 are no longer in a meshing state, and the horizontal rack 572 will automatically return to its initial position under the action of the reset spring 5794. At this time, the cleaning brush 571 cleans the bottom surface of the friction block 56 again.
