Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a yoga mat tear resistance detection device. Background Art

[0002] Yoga mats are usually made of polymer materials, such as PVC, TPE, EVA, etc. In order to ensure the quality and durability of yoga mats, quality control during the production process is essential. Tear resistance testing is an important part of quality control, which aims to ensure that each batch of products meets the predetermined quality standards.

[0003] Since the edges of yoga mats are subject to more pulling and abrasion during use, they are often the most prone to tearing. Existing yoga mat testing devices are usually only able to perform tear resistance tests on the entire yoga mat, but cannot specifically test the edges, making it impossible to identify and correct edge defects in a timely manner during the production process, increasing the defective rate.

[0004] For another example, a Chinese patent with announcement number CN112345353A discloses a yoga mat tear resistance detection device, which includes a clamping claw and a mounting column, wherein the clamping claw is rotatably connected to the middle position of the mounting column, a connecting shaft is inserted at the connection between the clamping claw and the mounting column, a mounting section is rotatably connected to the outer side of the connecting shaft, a clamping block is rotatably connected to one side of the mounting section, an arc groove is clamped in the middle of the clamping block, the arc groove is slidably connected to the clamping block, an input shaft is fixedly connected to one end of the arc groove away from the clamping block, the input shaft is driven by a motor located at its rear end, a bracket is slidably connected to the clamping block, an end of the bracket away from the clamping block is hinged to a spline shaft, the spline shaft is sleeved on the input shaft, one end of the bracket is hinged to the spline shaft, and a driving unit is installed on one side of the spline shaft.

[0005] The prior art has the following defects:

[0006] The above patent drives the clamping claws to shake under the transmission of the clamping block and the mounting section, thereby tearing the yoga mat. Although the tearing test of the yoga mat can be realized, it can only tear the yoga mat by shaking the yoga mat. The force application mode is single, and it is impossible to apply opposite force to the yoga mat to tear it. It is difficult to perform effective tearing test on the edge part, which may lead to insufficient edge performance evaluation and edge tearing problems in actual use of the product. Summary of the invention

[0007] In view of the problem that the existing yoga mat testing devices in the prior art are usually only able to perform tear resistance tests on the entire yoga mat but are unable to specifically test the edge portion of the yoga mat, a yoga mat tear resistance testing device is proposed.

[0020] 1. In the initial state, when the second mounting plate is located inside the first chamber, it is the first working state detected by the device. The two first fixing frames and the second fixing frames are located at the same height. The torsional stretching direction of the yoga mat by the first tension component is opposite to the torsional stretching direction of the yoga mat by the second tension component. Through the cooperation between the two first tension components and the second tension component, the edge portion of the yoga mat can be fully torn in opposite directions, and the tear resistance of the edge portion of the yoga mat can be fully tested to ensure that the edge portion can withstand the stress in actual use, reduce the risk of edge tearing during use, and improve user safety.

[0021] 2. When the second mounting plate is located inside the second chamber, it is the second working state detected by the device. The height of the second fixed frame rises synchronously, and the second fixed frame is no longer at the same height as the first fixed frame. At this time, through the cooperation between the two first tension components, the bidirectional threaded rod, the third fixed frame, the third clamping plate and the sliding platform, the yoga mat as a whole or its edge part can be subjected to a horizontal or vertical tensile test.

[0022] 3. When the second mounting plate is located inside the third chamber, it is the third working state detected by the device. The conical cylinder rises above the two first fixed frames. After the edge of the yoga mat is fixed inside the two first fixed frames, the output shaft of the driving motor is controlled to rotate, so that the two first tension components can be driven to move in opposite directions.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1, reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a yoga mat tear resistance detection device, including a workbench 1, a first tension component 2 for stretching the edge portion of the yoga mat is arranged on one side of the workbench 1, and a second tension component 3 for stretching the edge portion of the yoga mat is also arranged on one side of the workbench 1, and the first tension component 2 and the second tension component 3 tear the edge portion of the yoga mat in opposite directions.

[0039] Specifically, two first tension components 2 are provided, and the stretching direction of the yoga mat by the first tension component 2 is opposite to the stretching direction of the yoga mat by the second tension component 3, and the second tension component 3 is located between the two first tension components 2. Through the cooperation between the two first tension components 2 and the second tension component 3, the edge portion of the yoga mat can be fully torn in opposite directions, and the tear resistance of the edge portion of the yoga mat is fully tested, ensuring that the edge portion can withstand the stress in actual use, reducing the risk of edge tearing during use, and improving user safety.

[0040] Reference Figure 1-Figure 5 The first pulling component 2 includes a first mounting seat 10 slidably mounted on one side of the workbench 1, a first fixed disk 11 fixedly mounted on the top surface of the first mounting seat 10, a first rotating frame 4 rotatably mounted on the outer wall of the first fixed disk 11 through a first rotating shaft, a first self-locking motor 9 fixedly mounted on a side of the first fixed disk 11 away from the first rotating frame 4, a first fixed frame 5 fixedly mounted at one end of the first rotating frame 4, a first clamping plate 6 slidably mounted inside the first fixed frame 5, and a first screw 7 mounted on the outer wall of the first fixed frame 5 through internal and external threaded fittings, and the output shaft of the first self-locking motor 9 is fixedly connected to the axial end of the first rotating shaft, the end of the first screw 7 is rotatably connected to the outer wall of the first clamping plate 6, and the outer wall of the first clamping plate 6 is slidably fitted with the inner wall of the first fixed frame 5.

[0041] The second pulling component 3 includes a second mounting seat 12 slidably mounted on one side of the workbench 1, a second fixed plate 13 fixedly mounted on the bottom surface of the second mounting seat 12, a second rotating frame 14 rotatably mounted on the outer wall of the second fixed plate 13 through a second rotating shaft, a second self-locking motor 15 fixedly mounted on a side of the second fixed plate 13 away from the second rotating frame 14, a second fixed frame 16 fixedly mounted at one end of the second rotating frame 14, a second clamping plate 18 slidably mounted inside the second fixed frame 16, and a second screw 17 mounted on the outer wall of the second fixed frame 16 through internal and external threaded fittings, and the output shaft of the second self-locking motor 15 is fixedly connected to the axial end of the second rotating shaft, the end of the second screw 17 is rotatably connected to the outer wall of the second clamping plate 18, and the outer wall of the second clamping plate 18 is slidably fitted with the inner wall of the second fixed frame 16.

[0042] Specifically, the first self-locking motor 9 and the second self-locking motor 15 can be stepper motors or servo motors commonly used in the prior art. Through their built-in brakes or control systems, the first rotating frame 4 and the second rotating frame 14 can be kept in a fixed position after rotation. The bottom surfaces of the first clamping plate 6 and the second clamping plate 18 are both serrated, which is beneficial to increase the friction between the yoga mat and improve the fixing effect on the edge of the yoga mat.

[0043] Place the edge portion of the yoga mat into the first fixed frame 5 and the second fixed frame 16, and then rotate the first screw 7 to drive the first clamping plate 6 to slide inside the first fixed frame 5 until the first clamping plate 6 firmly fixes the edge portion of the yoga mat. Similarly, rotate the second screw 17 to enable the second clamping plate 18 to firmly fix the edge portion of the yoga mat. Then, by controlling the rotation of the output shaft of the first self-locking motor 9, the first rotating frame 4 can be driven to rotate away from the workbench 1. By controlling the rotation of the output shaft of the second self-locking motor 15, the second rotating frame 14 can be driven to rotate away from the workbench 1, thereby realizing the opposite tearing of the edge portion of the yoga mat.

[0044] Reference Figure 1-Figure 3 A sliding platform 41 is fixedly installed on the top surface of the workbench 1, and a sliding seat 19 is slidably installed inside the sliding platform 41. A third fixed frame 42 is fixedly installed on the top surface of the sliding seat 19. A third clamping plate 43 is slidably installed inside the third fixed frame 42. The outer wall of the third fixed frame 42 is connected with a third screw 44 through internal and external threads, and the outer wall of the third clamping plate 43 is slidably fitted with the inner wall of the third fixed frame 42, and the end of the third screw 44 is rotatably connected to the top surface of the third clamping plate 43.

[0045] Specifically, by rotating the third screw 44, the third clamping plate 43 can be driven to slide inside the third fixed frame 42, so that the edge portion of the yoga mat away from the first tension component 2 can be clamped and fixed. The bottom surface of the third clamping plate 43 is also serrated, which effectively increases the friction between the yoga mat and the yoga mat. The sliding platform 41 can be a linear guide slide or a pneumatic slide commonly used in the prior art. A linear guide slide is preferably used here. By controlling the operation of the sliding platform 41, the sliding seat 19 can be driven to slide horizontally, so as to adapt to yoga mats of different lengths and widths, thereby improving the applicability of the device.

[0046] Reference Figure 4-Figure 5 The first tension member 2 further includes a first roller 20 rotatably mounted at the other end of the first rotating frame 4. The second tension member 3 further includes a second roller 23 rotatably mounted at the other end of the second rotating frame 14.

[0047] Specifically, by setting the first roller 20, the first tension component 2 can lift up the middle part of the yoga mat during the process of tearing the edge part of the yoga mat, and then fix it by the third fixed frame 42 and the third clamping plate 43, which can further improve the stretching effect of the yoga mat. The function and effect of the second roller 23 are the same as above.

[0048] Reference Figure 4-Figure 5 The first tension component 2 further includes a first scale plate 21 fixedly mounted on the outer wall of the first fixed plate 11, and a first pointer 22 fixedly mounted on the outer wall of the first rotating frame 4. The second tension component 3 further includes a second scale plate 24 fixedly mounted on the outer wall of the second fixed plate 13, and a second pointer 25 fixedly mounted on the outer wall of the second rotating frame 14.

[0049] Specifically, the first pointer 22 points to the first dial 21. When the first rotating frame 4 rotates, the staff can more clearly and intuitively understand the rotation angle of the first rotating frame 4. The second pointer 25 points to the second dial 24. When the second rotating frame 14 rotates, the staff can more clearly and intuitively understand the rotation angle of the second rotating frame 14.

[0050] Reference Figure 1-Figure 2 A first mounting plate 26 is fixedly installed on one side of the workbench 1, a bidirectional threaded rod 27 is rotatably installed on the outer wall of the first mounting plate 26, a guide rod 28 is fixedly installed on the outer wall of the first mounting plate 26, a driving motor 8 is fixedly installed on the side of the first mounting plate 26 away from the bidirectional threaded rod 27, and the output shaft of the driving motor 8 is fixedly connected to the axial end of the bidirectional threaded rod 27; two first tension components 2 are provided, and the first mounting seats 10 in the two first tension components 2 are symmetrically installed on the rod wall of the bidirectional threaded rod 27 through internal and external threads, and the first mounting seats 10 are slidably installed on the rod wall of the guide rod 28.

[0051] Specifically, the drive motor 8 can be a servo motor or a DC motor commonly used in the prior art. The thread direction of the outer wall of the bidirectional threaded rod 27 from the middle to one end is opposite to the thread direction from the middle to the other end. By controlling the rotation of the output shaft of the drive motor 8, the first mounting seats 10 in the two first tension components 2 can be driven to move synchronously in relative or opposite directions, thereby flexibly adjusting the positions of the two first tension components 2, and testing the tearing effect on the edge of the yoga mat under the action of tension at different distances, thereby further improving the convenience and applicability of the device.

[0052] Example 2, reference Figure 1-Figure 11 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0053] A vertical plate 29 is fixedly mounted on the outer wall of the workbench 1, a through cavity 30 is opened on the top of the vertical plate 29, a second mounting plate 34 is slidably mounted inside the through cavity 30, a support rod 35 is fixedly mounted on the outer wall of the second mounting plate 34, and the second mounting seat 12 is fixedly mounted on the rod wall of the support rod 35.

[0054] Specifically, the second mounting plate 34 and the support rod 35 can provide a mounting space for the second mounting seat 12 , and the through cavity 30 can enable the second mounting plate 34 to move up and down inside the through cavity 30 , thereby enabling the second tension member 3 to move up and down.

[0055] Reference Figure 3 The through cavity 30 is divided into a first cavity 31, a second cavity 32 and a third cavity 33 from bottom to top.

[0056] Specifically, the through cavity 30 is divided into a first cavity 31 , a second cavity 32 and a third cavity 33 from bottom to top, which reflects different working states of the device.

[0057] When the second mounting plate 34 is located inside the first chamber 31, it is the first working state detected by the device. The two first fixing frames 5 and the second fixing frame 16 are located at the same height, and the edge portion of the yoga mat can be subjected to opposite tearing test.

[0058] When the second mounting plate 34 is located inside the second chamber 32, it is the second working state detected by the device. The height of the second fixed frame 16 rises synchronously, and the second fixed frame 16 is no longer at the same height as the first fixed frame 5. At this time, through the cooperation between the two first tension components 2, the bidirectional threaded rod 27, the third fixed frame 42, the third clamping plate 43 and the sliding platform 41, the yoga mat as a whole or its edge portion can be subjected to a horizontal or vertical tensile test.

[0059] Reference Figure 3 A lifting plate 36 is fixedly mounted on the outer wall of the second mounting plate 34 , an electric telescopic rod 37 is fixedly mounted on the outer wall of the vertical plate 29 , and a movable end of the electric telescopic rod 37 is fixedly connected to the bottom surface of the lifting plate 36 .

[0060] Specifically, the electric telescopic rod 37 can be an electric hydraulic telescopic rod or an electric cylinder telescopic rod commonly used in the prior art, and by controlling the movable end of the electric telescopic rod 37 to extend or retract, the lifting plate 36 can be driven to rise or fall, thereby driving the second mounting plate 34 to rise or fall, and providing power for the lifting and lowering of the second tension member 3. The rest of the structure is the same as that of embodiment 1.

[0061] Example 3, reference Figure 1-Figure 7 ,as well as Fig.12 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that a conical cylinder 40 is slidably installed between the two first tension members 2, a connecting plate 38 is fixedly connected to the outer wall of the second mounting plate 34, a corrugated plate 39 is fixedly installed on the outer wall of the connecting plate 38, and the top surface of the corrugated plate 39 is fixedly connected to the bottom surface of the conical cylinder 40.

[0062] Specifically, through the action of the connecting plate 38 and the corrugated plate 39, an installation space can be provided for the conical tube 40. The corrugated plate 39 props up the conical tube 40 in an oblique upward direction, providing the conical tube 40 with space for stretching the yoga mat. The surface of the conical tube 40 is smooth and will not cause damage to the material of the yoga mat itself.

[0063] When the second mounting plate 34 is located inside the third chamber 33, it is the third working state detected by the device. The conical cylinder 40 rises above the two first fixing frames 5. After the edge of the yoga mat is fixed inside the two first fixing frames 5, the output shaft of the driving motor 8 is controlled to rotate, which can drive the two first tension components 2 to move in opposite directions. The two first tension components 2 can perform a horizontal stretching test on the edge of the yoga mat. At the same time, by controlling the conical cylinder 40 to rise, the conical cylinder 40 can lift the yoga mat upward, further stretch the yoga mat, and increase the detection of the stretching capacity of the yoga mat. The rest of the structure is the same as that of Example 2.

[0064] Based on Example 1 to Example 3, the working principle of the present invention is as follows:

[0065] When it is necessary to test the tear resistance of the yoga mat, by controlling the rotation of the output shaft of the driving motor 8, the first mounting seats 10 in the two first tension components 2 can be driven to move synchronously in relative or opposite directions, so that the positions of the two first tension components 2 can be flexibly adjusted to test the tearing effect on the edge of the yoga mat under the action of tension at different distances, thereby further improving the convenience and applicability of the device.

[0066] When the positions of the two first tension members 2 are adjusted, firstly, by rotating the third screw 44, the third clamping plate 43 can be driven to slide inside the third fixed frame 42, so that the edge portion of the yoga mat away from the first tension member 2 can be clamped and fixed. In the initial state, the second mounting plate 34 is located inside the first chamber 31, which is the first working state detected by the device. The two first fixed frames 5 and the second fixed frame 16 are located at the same height. Then, the edge portion of the yoga mat close to the first tension member 2 is placed in the first fixed frame 5 and the second fixed frame 16. By rotating the first screw 7, the first clamping plate 6 can be driven to slide inside the first fixed frame 5 until the first clamp The holding plate 6 firmly fixes the edge portion of the yoga mat. Similarly, by rotating the second screw 17, the second clamping plate 18 can firmly fix the edge portion of the yoga mat. Then, by controlling the rotation of the output shaft of the first self-locking motor 9, the first rotating frame 4 can be driven to rotate away from the workbench 1. The first pointer 22 points to the first dial 21, and the staff can clearly and intuitively understand the rotation angle of the first rotating frame 4. By controlling the rotation of the output shaft of the second self-locking motor 15, the second rotating frame 14 can be driven to rotate away from the workbench 1. The second pointer 25 points to the second dial 24, and the staff can clearly and intuitively understand the rotation angle of the second rotating frame 14.

[0067] Two first tension components 2 are provided, and the torsional stretching direction of the yoga mat by the first tension component 2 is opposite to the torsional stretching direction of the yoga mat by the second tension component 3. Through the cooperation between the two first tension components 2 and the second tension component 3, the edge portion of the yoga mat can be fully torn in opposite directions, and the tear resistance of the edge portion of the yoga mat can be fully tested to ensure that the edge portion can withstand the stress in actual use, reduce the risk of edge tearing during use, and improve user safety.

[0068] In addition, the first tension component 2 and the second tension component 3 are controlled to return to the initial state, and the yoga mat is taken out from the second fixed frame 16. By controlling the movable end of the electric telescopic rod 37 to extend, the lifting plate 36 can be driven to rise, and then the second mounting plate 34 can be driven to rise. The rising of the second mounting plate 34 can drive the second tension component 3 to rise as a whole.

[0069] When the second mounting plate 34 is located inside the second chamber 32, it is the second working state detected by the present device, and the height of the second fixed frame 16 rises synchronously, and the second fixed frame 16 is no longer at the same height as the first fixed frame 5. At this time, through the cooperation between the two first tension components 2, the bidirectional threaded rod 27, the third fixed frame 42, the third clamping plate 43 and the sliding platform 41, the yoga mat as a whole or the edge portion can be subjected to a transverse or longitudinal tensile test, and by controlling the rotation of the output shaft of the drive motor 8, the two first tension components 2 can be driven to move in opposite directions, and the two first tension components 2 can perform a transverse tensile test on the edge portion of the yoga mat, and by controlling the operation of the sliding platform 41 to make the sliding seat 19 move in a direction away from the first tension component 2, the yoga mat as a whole can be subjected to a longitudinal tensile test.

[0070] Finally, the first tension component 2 and the sliding platform 41 are controlled to return to the initial state, and the movable end of the electric telescopic rod 37 is controlled to continue to rise. When the second mounting plate 34 is located inside the third chamber 33, it is the third working state detected by the present device. The conical cylinder 40 rises above the two first fixed frames 5. After the edge of the yoga mat is fixed inside the two first fixed frames 5, the output shaft of the driving motor 8 is controlled to rotate, so that the two first tension components 2 can be driven to move in opposite directions. The two first tension components 2 can perform a lateral stretch test on the edge of the yoga mat. At the same time, the conical cylinder 40 is controlled to continue to rise. The conical cylinder 40 can continuously lift the yoga mat upwards, and further perform a stretch test on the yoga mat, thereby increasing the detection of the stretching capacity of the edge of the yoga mat.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
