Description

Technical Field

[0001] The invention relates to the technical field of tensile testing, in particular to a tensile testing mechanism for buttons used in textile clothing. Background Art

[0002] Clothing buttons are small spherical or sheet-like objects that are inserted into button loops to fasten clothes together. They play a key role in clothing production and wearing. Their function is to connect the opening parts of clothes so that the clothes can be kept on the human body, providing coverage and warmth, and ensuring that the wearer's clothes will not fall apart during various activities. In some clothing styles, buttons can adjust the tightness and wearing effect of clothes through different fastening methods.

[0003] Clothing buttons require tensile testing. This test provides an intuitive understanding of how secure buttons are when subjected to certain external forces. For example, during daily wear, clothing may experience tension due to body movement, friction, and other factors. Only buttons that can withstand this tension will not easily fall off, thus ensuring the overall quality and performance of the garment.

[0004] In the patent document with announcement number CN118641355B, a digital button tensile tester is proposed. Through the cooperation of the square plate and the detection head moving mechanism, the first motor drives the cam to rotate, and the detection head rotation adjustment mechanism drives the disc to move backward. The disc drives the detection head fixed below to move, so that the detection head is removed from the upper surface of the workbench. Then, the operator places the clothes at the lower end of the button on the workbench and fixes it through an external fixing device. In the above method, the detection head is moved to the workbench, and the button is fixed by the groove on the surface of the detection head. In the above method, the button can be fixed on the detection head without the operator placing the button, thereby reducing the workload of the operator.

[0005] However, the spacing between the stitching lines of buttons of different sizes is different, so the tension they can withstand is different. In addition, the spacing between the stitching lines of buttons needs to be measured to test the spacing between the stitching lines and adjust the tensile test qualification parameters, thereby reducing the detection efficiency. Summary of the Invention

[0006] The purpose of the present invention is to address the problem in the background technology that measuring the distance between sutures and adjusting parameters reduces the detection efficiency, and to propose a button tension testing mechanism for textile clothing.

The end of the slider is fixedly connected to the detection support plate. A hydraulic push rod is fixedly connected to the top of the hydraulic telescopic rod. A docking tube is fixedly installed on the top of the hydraulic telescopic rod. The two ends of the detection tension spring are elastically connected to the slider and the docking tube respectively.

[0014] Optionally, a symmetrically arranged guide rod is fixedly installed on the top of the shovel claw, and the guide rod slides up and down along the slider. A forward rod passing through the center of the detection tension spring is fixedly installed at the bottom center of the slider, and the forward rod is slidably connected to the docking tube.

[0015] Optionally, an over-protection component is also included, which includes a circular plate, an obstruction block, an avoidance groove and an obstruction spring. The circular plate is fixedly installed on the top of the hydraulic telescopic rod, and the inside of the hydraulic telescopic rod is provided with symmetrically arranged avoidance grooves. The inside of the avoidance groove is slidingly connected to the obstruction block, and the obstruction spring is elastically connected between the obstruction block and the avoidance groove, and the obstruction block is clamped to the circular plate.

[0016] Optionally, the end of the blocking block adopts a chamfered structure, and the end of the blocking block includes an upper inclined surface and a lower inclined surface. The inclination angle of the upper inclined surface at the end of the blocking block is larger than the inclination angle of the lower inclined surface at the end of the blocking block.

An annular groove concentric with the center button table is opened on the top of the table plate. A pressure ring is placed in the annular groove. After the pressure ring is placed inside the annular groove, its top height is lower than the center button table.

[0019] Optionally, a disengagement rod is fixedly installed at the bottom of the pressure ring, and the bottom end of the disengagement rod passes through the table. Two upward rods are provided and symmetrically distributed on both sides of the pressure ring, and a common connecting plate is fixedly installed at the ends of the two upward rods.

[0020] Compared with the prior art, this application has the following beneficial technical effects:

[0021] 1. The present invention connects the ends of two shovel claws and shovels under the button, using the button suture to squeeze the deflection plate, causing the deflection plate to move and push the hydraulic oil in the hydraulic piston rod into the hydraulic telescopic rod, thereby extending the length of the hydraulic telescopic rod. During a tensile test, when the electric telescopic rod contracts the same distance, the pulling force of the shovel claw on the button is reduced. When conducting tensile tests on buttons of different sizes, the pulling force is adjusted, reducing the steps of testing the position of the suture holes on the button and improving detection efficiency.

[0022] 2. Even for buttons of the same type, the machine will wear out over a long period of time during sewing, resulting in changes in sewing accuracy and changes in the spacing between adjacent sewing lines. Therefore, when testing buttons of the same type, the change in the spacing between adjacent sewing lines can be used to reversely detect changes in the mechanical accuracy of the sewing button, prompting maintenance.

[0023] 3. When the pulling force of the shovel claw on the button is greater than the set qualified pulling force, the circular plate moves from above the obstruction block to below the obstruction block. At this time, the shovel claw no longer applies pulling force to the button. Therefore, after the pulling force exceeds the set qualified pulling force, it provides space for the circular plate to move, avoiding excessive test pulling force that affects the normal use of the button.

[0024] 4. The textile is buckled into the annular groove through the pressure ring to fix the position of the textile, and the button is fixed at the center of the center button platform. The upward rod prevents the pressure ring from moving upward. The diameter of the pressure ring determines the area of the textile involved in the button tensile test. At the same time, the pressure ring and the annular groove cooperate to fully unfold the textile to avoid wrinkles affecting the tensile test. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] Example 1: This example proposes a button tension testing mechanism for textile clothing, such as Figure 1 As shown, it includes an inspection workbench 1, an equipment support frame 2 is fixedly installed on the top and near the right side of the inspection workbench 1, the equipment support frame 2 adopts an L-shaped structure, an electric telescopic rod 3 is fixedly installed below the horizontal plane of the equipment support frame 2, and a misalignment platform 6 is fixedly installed at the top center of the inspection workbench 1, and a placement platform 7 for fixing textiles is set on the top of the misalignment platform 6.

[0041] like Figure 2 and Figure 3As shown, a tension test assembly 4 is provided at the bottom end of the electric telescopic rod 3. The tension test assembly 4 includes a tension member, a hydraulic telescopic rod 45, a shovel claw 46, a deflection plate 47, an extension plate 48 and a hydraulic piston rod 49. The tension member includes a detection support plate 41, a slider 42 and a detection tension spring 43. The top center of the detection support plate 41 is fixedly connected to the electric telescopic rod 3. The inner ring of the detection support plate 41 is slidably connected to the slider 42. The end of the slider 42 is fixedly connected to the detection support plate 41. A hydraulic push rod is fixedly connected between the end of the slider 42 and the detection support plate 41. Figure 5 As shown, the top of the hydraulic telescopic rod 45 is fixedly installed with the docking tube 44, the two ends of the detection tension spring 43 are elastically connected to the slider 42 and the docking tube 44 respectively, and the bottom of the hydraulic telescopic rod 45 is fixedly installed with a shovel claw 46.

[0042] Two shovel claws 46 are provided and are symmetrical about the axis of the electric telescopic rod 3. The two shovel claws 46 move toward each other by sliding the slider 42. The two shovel claws 46 clamp the button together, and the heads of the two shovel claws 46 are docked. Then, the electric telescopic rod 3 is contracted to move the tensile member, the hydraulic telescopic rod 45 and the shovel claws 46 upward, thereby pulling the button to perform a tensile test on it.

[0043] The shovel claw 46 adopts a U-shaped structure, and the end of the shovel claw 46 is chamfered, and the top of the chamfer of the shovel claw 46 contacts the button. The shovel claw 46 with a chamfered end is easy to insert between the button and the textile, so that the shovel claw 46 is located below the button to pull the button.

[0044] like Figure 3 and Figure 4 As shown, both ends of the shovel claw 46 are slidably connected to the deflection plate 47, and the extension plate 48 is fixedly installed on the side of the deflection plate 47 facing the center of the shovel claw 46. The hydraulic piston rod 49 is fixedly installed on the side of the extension plate 48 away from the deflection plate 47, and the hydraulic piston rod 49 is connected to the hydraulic telescopic rod 45.

[0045] During the process of the two shovel claws 46 moving toward each other, the deviation plate 47 is blocked by the suture line of the button, and movement occurs between the deviation plate 47 and the shovel claw 46. The deviation plate 47 uses the extension plate 48 to push the hydraulic oil in the hydraulic piston rod 49 into the hydraulic telescopic rod 45, thereby extending the length of the hydraulic telescopic rod 45. During the tensile test, when the electric telescopic rod 3 contracts the same distance, the pulling force of the shovel claw 46 on the button is reduced.

[0046] The deflection plates 47 on the two shovel claws 46 are in contact with the button suture line. The greater the distance between the button suture line and the center of the button, the smaller the tension that the button can withstand. Therefore, when performing tension tests on buttons of different sizes, the tension can be adjusted, the steps of testing the position of the suture holes on the button are reduced, and the detection efficiency is improved.

[0047] At the same time, even for buttons of the same type, when sewing, the machine will wear out due to long-term sewing, resulting in changes in sewing accuracy and changes in the spacing between adjacent sewing lines. Therefore, when testing buttons of the same type, the changes in the spacing between adjacent sewing lines can be used to reversely test whether the mechanical accuracy of the sewing button has changed, prompting maintenance.

[0048] The inner diameter of the hydraulic piston rod 49 is smaller than the inner diameter of the hydraulic telescopic rod 45. The extension plate 48 adopts an L-shaped structure. The side of the deviation plate 47 away from the extension plate 48 adopts a rounded structure to prevent the deviation plate 47 from cutting the suture line. The piston in the hydraulic piston rod 49 is elastically connected to the reset spring 411. The reset spring 411 is used to reset the hydraulic piston rod 49. The resistance to the movement of the hydraulic piston rod 49 is smaller than that of the hydraulic telescopic rod 45. The force required to move the hydraulic telescopic rod 45 is large. The pulling force of the test button is generally 50N-90N. The hydraulic telescopic rod 45 adopts a small hydraulic oil rod. The pulling force that the small hydraulic oil rod can withstand is usually above 2000N, avoiding the detection tension spring 43 causing the length of the hydraulic telescopic rod 45 to change.

[0049] A symmetrically arranged guide rod 410 is fixedly mounted on the top of the shovel claw 46. The guide rod 410 slides up and down along the slider 42. A forward rod, which passes through the center of the detection tension spring 43, is fixedly mounted at the bottom center of the slider 42. The forward rod is slidably connected to the docking tube 44. The forward rod prevents the detection tension spring 43 from bending, and the two guide rods 410 prevent the shovel claw 46 from rotating.

[0050] In this embodiment, the ends of the two shovel claws 46 are docked and shoveled under the button, and the button suture is used to squeeze the deviation plate 47. The deviation plate 47 moves and pushes the hydraulic oil in the hydraulic piston rod 49 into the hydraulic telescopic rod 45, thereby extending the length of the hydraulic telescopic rod 45. When performing a tensile test, when the electric telescopic rod 3 contracts the same distance, the pulling force of the shovel claw 46 on the button is reduced. When performing a tensile test on buttons of different sizes, the pulling force is adjusted, the steps of testing the position of the suture holes on the button are reduced, and the detection efficiency is improved.

[0051] Example 2: Based on Example 1, this example proposes a button tension testing mechanism for textile clothing, such as Figure 6 and Figure 7 As shown, an over-protection component 5 is arranged between the hydraulic telescopic rod 45 and the docking tube 44. The over-protection component 5 includes a circular plate 51, an obstruction block 52, an avoidance groove 55 and an obstruction spring 56. The circular plate 51 is fixedly installed on the top of the hydraulic telescopic rod 45. The inside of the hydraulic telescopic rod 45 is provided with symmetrically arranged avoidance grooves 55. The inside of the avoidance groove 55 is slidingly connected to the obstruction block 52. The obstruction spring 56 is elastically connected between the obstruction block 52 and the avoidance groove 55. The obstruction block 52 is clamped with the circular plate 51.

[0052] The obstruction block 52 blocks the movement of the circular plate 51, and the electric telescopic rod 3 contracts to cause the docking tube 44 to pull the hydraulic telescopic rod 45 and the shovel claw 46 to test the pulling force of the button. When the pulling force of the shovel claw 46 on the button is greater than the set qualified pulling force, the pushing force of the circular plate 51 on the obstruction block 52 is greater than the obstruction force of the obstruction block 52 on the circular plate 51. At this time, the circular plate 51 presses the obstruction block 52 into the avoidance groove 55, and the circular plate 51 moves from above the obstruction block 52 to below the obstruction block 52. At this time, the shovel claw 46 no longer applies pulling force to the button, so it will stop immediately after the pulling force exceeds the set qualified pulling force to avoid excessive test pulling force affecting the normal use of the button.

[0053] The end of the obstruction block 52 is chamfered and includes an upper bevel 53 and a lower bevel 54. The angle of the upper bevel 53 is greater than that of the lower bevel 54. The circular plate 51 is formed of two upper and lower cones, with the upper bevel 53 of the obstruction block 52 abutting against the lower cone. The downward movement of the circular plate 51 encounters greater resistance from the obstruction block 52 than its upward movement. The electric telescopic rod 3 is fully extended, causing the shovel claw 46 to abut against the placement platform 7. This forces the circular plate 51 upward and causes it to move above the obstruction block 52, thereby resetting.

[0054] There is a gap between the ground of the obstruction block 52 and the bottom inner wall of the docking tube 44, which provides sliding space for the obstruction block 52, thereby preventing the detection tension spring 43 from being under pressure for a long time and the circular plate 51 from sliding up and down inside the docking tube 44.

[0055] In this embodiment, when the pulling force of the shovel claw 46 on the button is greater than the set qualified pulling force, the circular plate 51 moves from above the blocking block 52 to below the blocking block 52. At this time, the shovel claw 46 no longer applies pulling force to the button. Therefore, after the pulling force exceeds the set qualified pulling force, it provides moving space for the circular plate 51 to avoid the test pulling force being too large, which affects the normal use of the button.

[0056] Example 3: Based on the above-mentioned Example 1 or 2, this example proposes a button tension testing mechanism for textile clothing, such as Figure 8 and Figure 9 As shown, the placement table 7 includes a table plate 71, an annular groove 72, a center button table 73, a pressure ring 74 and an upward rod 77. Textiles are placed on the top of the table plate 71. A center button table 73 is opened at the center of the table plate 71. The buttons on the textiles are placed at the center of the center button table 73. An annular groove 72 coaxial with the center button table 73 is opened on the top of the table plate 71. A pressure ring 74 is placed in the annular groove 72. After the pressure ring 74 is placed inside the annular groove 72, its top height is lower than the center button table 73. An upward rod 77 covering the top of the pressure ring 74 is inserted into the interior of the table plate 71.

[0057] The textile is fixed on the top of the platform 71 by the cooperation of the pressure ring 74 and the annular groove 72. At the same time, the pressure ring 74 fixes the button at the center of the central button platform 73 and uses the upward rod 77 to prevent the pressure ring 74 from moving upward.

[0058] A disengagement rod 75 is fixedly installed at the bottom of the pressure ring 74. The bottom end of the disengagement rod 75 passes through the table 71. The disengagement rod 75 can be pushed from the bottom of the table 71 to disengage the pressure ring 74 from the annular groove 72. Two upward rods 77 are provided and symmetrically distributed on both sides of the pressure ring 74. The ends of the two upward rods 77 are fixedly installed with a common connecting plate 76.

[0059] In this embodiment, the textile is buckled in the annular groove 72 by the pressure ring 74, thereby fixing the position of the textile, and at the same time fixing the button at the center of the central button platform 73. The upward rod 77 prevents the pressure ring 74 from moving upward. The diameter of the pressure ring 74 determines the area of the textile participating in the button tensile test. At the same time, the pressure ring 74 and the annular groove 72 cooperate to fully unfold the textile to avoid wrinkles affecting the tensile test.

[0060] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
