Description

Technical Field

[0001] The invention relates to the technical field of sole bending resistance detection, in particular to a bending strength detection device for a new material sports shoe sole. Background Art

[0002] The new materials in the new material soles include ethylene vinyl acetate, thermoplastic polyurethane and polyurethane, among which polyurethane is more widely used. As a polymer material with high strength, tear resistance, wear resistance and other characteristics, the new material soles have certain wear resistance and crack resistance. However, the new material soles still need to be tested for bending strength during the completion of the shoe products. The bending strength testing device is used to test the new material soles, which is a very important link in the design and manufacture of footwear. The purpose of the bending strength test of the soles is to evaluate the comfort, durability and safety of the soles, and to ensure their performance during normal use. Through the testing method, the performance of the soles can be scientifically evaluated, providing a basis for the design and production of footwear products, and ensuring product quality and consumer satisfaction.

[0003] However, the existing sole bending detection device is mainly used to evaluate the bending resistance of the sole, and is suitable for various types of sole materials, especially non-leather soles. Through repeated bending tests, the bending resistance of the sole can be understood to ensure the durability and comfort of the sole. However, a single bending motion state is difficult to simulate the wear and pressure of the sole during actual walking, resulting in a deviation between the final sole detection result and the actual result.

[0004] Chinese Patent Document Announcement No. (CN114659904A) "A polyurethane sole bending strength testing device includes a base plate, a support plate and a partition plate. The support plate is connected to the top of the base plate, and the partition plate is installed on one side of the support plate. The partition plate is provided with a test module and a conveying module. The movable end of the cylinder first brings the transmission plate down, and the left end of the movable plate tilts up. The extrusion plate connected to the left end of the movable plate drives the piston to rise. The air in the hollow rectangular column moves the elastic pad in the conveying box through the main air pipe and the auxiliary air pipe. The elastic pad pushes the sole located at the bottom of the material frame to between the two limit plates, and then the movable end of the cylinder rises, and the movable plate rotates in the opposite direction. The second gear indirectly connected to the movable plate descends the tooth plate, and the tooth plate presses the middle part of the sole, and then cooperates with the rotating movable plate to complete the bending strength test. The sole can be conveyed and tested by only one cylinder, which reduces the manufacturing cost of the device and improves its market competitiveness." Although the above patent document can shorten the detection cycle and save costs, it is difficult to simulate the wear of the sole during actual walking. Summary of the invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The present invention drives the bending plate through a servo motor to make it swing back and forth along the axis of the hollow shaft, thereby achieving the purpose of detecting the bending movement of the sole. It can simulate the bending of the sole of the human foot during walking, running and other actions, evaluate the bending resistance of the sole, and ensure the accuracy and reliability of the test results. In order to achieve the best test effect, the speed of the servo motor is carefully adjusted to 150 times / min. Such a speed setting can accurately simulate the pressure and bending degree of the sole when a person walks, thereby providing more real and reliable test data. Through such precise control and simulation, it is possible to effectively detect problems that may occur in the sole during actual use, thereby ensuring the quality and durability of the shoes.

[0029] (2) The present invention drives the rubber pressure ring to apply appropriate pressure to the heel of the sole through the driving action of the cylinder, thereby achieving precise positioning of the sole and ensuring the quality control of the sole during the production process. When the rubber pressure ring contacts the sole and applies pressure, the rubber pressure ring will be in a compressed state. The compressed state helps to quickly and stably complete the compression and positioning of the sole, thereby greatly improving the work efficiency when compressing and positioning the sole. In addition, the preload force of the first spring can be adjusted through the threaded transmission action of the threaded knob and the threaded groove, which will increase the preload force when the sole is compressed, thereby effectively preventing the displacement of the sole due to insufficient compression effect during the bending detection of the sole, ensuring the stability of the sole during the detection process, thereby improving the accuracy and reliability of the detection, and also improving the production efficiency and the overall quality of the product.

[0030] (3) The present invention can effectively simulate the various pressures generated between the sole and the ground, as well as objects such as stones on the road surface when a person is walking by applying pressure to the sole using a pressure plate. This simulation mechanism enables us to more realistically reproduce the actual walking scene when performing a sole bending test, thereby improving the accuracy and practicality of the test results. In this way, the durability and performance of the sole in actual use can be better evaluated, ensuring that the shoe can provide sufficient comfort and support during long-term wear. Not only can the bending performance of the sole be tested, but the pressure resistance of the heel part of the sole can also be tested in the same process, thereby comprehensively evaluating the overall quality of the shoe.

[0031] (4) When the angle between the bending plate and the load-bearing plate changes, the present invention can effectively drive the friction plate to move back and forth along the inside of the slide groove through the second connecting rod transmission mechanism, which can accurately simulate the friction phenomenon generated between the sole and the ground during human walking. Therefore, while performing the sole bending test, the wear resistance of the sole can also be synchronously tested and evaluated, and multiple important sole performance evaluations can be completed simultaneously in one test, greatly improving the test efficiency and accuracy.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0048] Example 1

[0049] See also Figure 1-Figure 14 The bending strength testing device for the sole of a new material sports shoe shown in the figure comprises a load-bearing plate 1 and a bending plate 2 arranged on the load-bearing plate 1, and a sole is placed on the load-bearing plate 1, and also comprises a frame 3 fixed on the load-bearing plate 1, and a pressing unit 4 is fixed on the frame 3, and the pressing unit 4 is used to press and position the sole, and a bending measuring component 5 matched with the bending plate 2 is arranged on the frame 3, and the bending measuring component 5 is used to bend the sole back and forth, and a weight pressure test unit 6 arranged on the load-bearing plate 1, and the weight pressure test unit 6 is used to simulate the force condition of the sole when walking, and a walking simulation wear unit 7 matched with the bending plate 2 is arranged on the frame 3, and the walking simulation wear unit 7 simulates the wear degree of the sole when walking;

[0050] It should be noted that the length of the bending plate 2 is greater than that of the load-bearing plate 1, and the seam line between the load-bearing plate 1 and the bending plate 2 is collinear with the center line of the sole, which can significantly improve the accuracy of the sole bending detection result, and the side wall adjacent to the bending plate 2 and the load-bearing plate 1 is arranged in an arc surface, ensuring that the bending plate 2 has sufficient smoothness when swinging back and forth, avoiding the situation where the bending plate 2 and the load-bearing plate 1 are jammed due to motion interference.

[0051] In this solution, the sole on the load-bearing plate 1 is pressed and positioned by a pressing unit, so that the heel part of the sole is pressed and positioned, and the bending plate 2 is driven by the bending measurement component 5 to swing back and forth to achieve the purpose of bending the sole. When the bending plate 2 swings back and forth, the weight pressure test unit 6 is linked to apply pressure to the heel of the sole, which can simulate the force condition of the heel when a person walks, and the walking simulation wear unit 7 rubs the forefoot part of the sole, thereby simulating the wear condition of the forefoot part of the sole when a person walks.

[0052] Further as Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig. 9 As shown, it is worth specifically explaining that the bending measurement component 5 includes a hollow shaft 501 fixed on the load-bearing plate 1, the optimal number of hollow shafts 501 is two, and the two hollow shafts 501 are symmetrically fixed on the load-bearing plate 1, and the bending plate 2 is rotatably connected to the hollow shaft 501, and when the bending plate 2 is subjected to force, it reciprocates along the axis of the hollow shaft 501, a support plate 502 is fixed on the frame 3, a servo motor 503 is fixed on the support plate 502, a rotating wheel 504 is coaxially fixed to the output shaft of the servo motor 503, and a first connecting rod 505 is hinged between the bending plate 2 and the rotating wheel 504;

[0053] Among them, a bending guide plate 15 is fixed on the frame 3, and a guide rod 16 is fixed on the bending plate 2, and a guide groove 17 for the guide rod 16 to slide is provided on the bending guide plate 15. By sliding the guide rod 16 in the guide groove 17, it not only guides the bending plate 2 when it swings, but also significantly improves the stability of the bending plate 2 when it swings back and forth, and avoids the bending plate 2 from getting stuck due to insufficient stability when it swings;

[0054] It should be noted that the servo motor 503 drives the rotating wheel 504 to rotate. After the bending test of the sole is completed, the bending plate 2 and the load-bearing plate 1 are located in the same plane, and the servo motor 503 is automatically reset through the feedback control system. When the motor is disturbed by the outside world, the feedback control system will automatically adjust the position of the motor to restore it to a normal working state.

[0055] It should also be noted that the servo motor 503 drives the bending plate 2 to swing back and forth along the axis of the hollow shaft 501, thereby achieving the purpose of detecting the bending movement of the sole, and the speed of the servo motor 503 is adjusted to 150 times / min, which can accurately simulate the stress conditions of the sole when a person walks, ensuring the accuracy and reliability of the test results.

[0056] Further as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown, it is worth specifically explaining that the pressing unit 4 includes a support frame 401 fixed on the frame 3, a cylinder 402 is fixed on the support frame 401, a rod body 403 is fixed to the output end of the cylinder 402, and a rubber pressure ring 404 is fixed to one end of the rod body 403, the rubber pressure ring 404 is made of a soft material, and two connecting rings 405 are sleeved on the rod body 403, and a first spring 406 is fixed between the two connecting rings 405, and a threaded groove 407 is provided on the rod body 403, and a threaded knob 408 abutting against the connecting ring 405 is threadedly connected at the threaded groove 407;

[0057] It should be noted that, through the driving action of the cylinder 402, the rubber pressure ring 404 is driven to apply pressure to the heel of the sole, so as to achieve accurate positioning of the sole. In this process, when the rubber pressure ring 404 contacts the sole and applies pressure, the rubber pressure ring 404 will be subjected to the corresponding force, so that it is in a compressed state. This compressed state helps to quickly and stably complete the compression and positioning work of the sole, thereby greatly improving the work efficiency when the sole is compressed and positioned.

[0058] It should also be noted that, driven by the cylinder 402, if it is necessary to increase the clamping force on the sole, it can be achieved by rotating the threaded knob 408. Through the threaded transmission action of the threaded knob 408 and the threaded groove 407, the first spring 406 is compressed to increase the pre-tightening force when pressing the sole, which can effectively prevent the displacement of the sole due to insufficient clamping effect during the bending detection of the sole, and can ensure the stability of the sole during the detection process, thereby improving the accuracy and reliability of the detection.

[0059] Embodiment 2: Based on Embodiment 1, according to Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.11 , Fig.13 and Fig.14As shown, it is worth specifically explaining that the weight pressure test unit 6 includes a rotating shaft 601 rotatably connected to the load-bearing plate 1, the central axis of the hollow shaft 501 is colinearly arranged with the central axis of the rotating shaft 601, a first groove 602 is provided on the load-bearing plate 1, and a worm 603 is fixed on the rotating shaft 601, two rotating seats 604 are fixed on the load-bearing plate 1, a transmission shaft 605 is rotatably connected in the two rotating seats 604, a worm wheel 606 meshing with the worm 603 is fixed on the transmission shaft 605, the worm 603 and the worm wheel 606 are both located inside the first groove 602, and a cam 607 fixed on the transmission shaft 605, and a second groove 608 is provided on the load-bearing plate 1, and a worm 603 is fixed on the load-bearing plate 1. A plurality of channels 609 are provided which are connected to the second groove 608. A pressure plate 6010 is slidably connected in the channel 609. The pressure plate 6010 is provided with a plurality of uneven protrusions. The cam 607 abuts against the pressure plate 6010. A connecting plate 6011 is fixed to the pressure plate 6010. The connecting plate 6011 is L-shaped. The angle between the connecting plate 6011 and the pressure plate 6010 is right angled. A second spring 6012 is fixed between the connecting plate 6011 and the groove. A spur gear 6013 is fixed to the rotating shaft 601. A toothed plate 6014 meshing with the spur gear 6013 is fixed to the bending plate 2. The toothed plate 6014 is arc-shaped.

[0060] It should be noted that when the bending plate 2 is subjected to an external force and reciprocates along the axis position of the hollow shaft 501, it can drive the toothed plate 6014 to synchronously swing accordingly. Through the meshing transmission mechanism between the toothed plate 6014 and the spur gear 6013, the swing can be converted into an indirect rotation of the rotating shaft 601, which can provide a necessary power source for the multiple pressure plates 6010, so that during the process of the sole bending test, pressure can be applied to the heel part of the sole at the same time. In this way, not only the bending performance of the sole can be tested, but also the pressure resistance performance of the heel part of the sole can be tested in the same process, so as to comprehensively evaluate the overall quality of the shoe.

[0061] It should also be noted that when the bending plate 2 and the load-bearing plate 1 remain horizontal, there is no contact between the pressure plate 6010 and the bottom surface of the sole. However, the angle between the bending plate 2 and the load-bearing plate 1 changes, and the pressure plate 6010 applies pressure to the sole, which can effectively simulate the pressure generated between the sole and the ground and objects such as road stones when a person is walking. Therefore, when conducting a sole bending test, this mechanism can make the test results closer to the actual walking scene, thereby improving the accuracy and practicality of the test.

[0062] Example 3: Please refer to Figure 4 , Figure 6 , Figure 7 , Fig.11 and Fig.12 As shown, this embodiment further illustrates other embodiments, and its difference lies in that a walking simulation wear unit 7 is added to the bending plate 2. It is worth specifically explaining that the walking simulation wear unit 7 includes two slide grooves 701 opened on the bending plate 2, and a friction plate 702 is slidably connected in the slide groove 701, and a through groove 703 connected to the slide groove 701 is opened on the bending plate 2. The friction plate 702 slides in the through groove 703 through a fixed sliding block 704. The vertical cross section of the sliding block 704 is set in a T shape. The shape of the sliding block 704 is used to ensure that the friction plate 702 is always located in the track opened in the through groove 703 for movement, so that the friction plate 702 is in a relatively stable state when moving, and a first hinge seat 705 is fixed on the sliding block 704. A second hinge seat 707 is fixed on the frame 3 through a connecting block 706, and a second connecting rod 708 is hinged between the second hinge seat 707 and the first hinge seat 705;

[0063] It should be noted that when the angle between the bending plate 2 and the load-bearing plate 1 changes, the friction plate 702 can be effectively driven to move back and forth along the inside of the slide groove 701 by the transmission of the second connecting rod 708, which can accurately simulate the friction phenomenon between the sole and the ground during human walking. In this way, while performing the bending test of the sole, the wear resistance of the sole can also be tested and evaluated synchronously, which is powerful in functionality.

[0064] It should also be noted that when the angle between the bending plate 2 and the load-bearing plate 1 remains in a parallel state and does not change, the friction plate 702 will not produce friction on the sole, so that while performing the sole bending detection, the friction loss phenomenon that occurs when the sole contacts the road surface during walking can be simulated. In this way, the wear and tear suffered by the sole during walking can be more realistically restored, thereby providing more accurate experimental data and reference basis for the research and improvement of sole materials and structures.

[0065] Example 4: Please refer to Figure 2 , Figure 5 , Figure 7 and Fig. 9 As shown, this embodiment further illustrates other embodiments, and the difference lies in that a positioning pressure ring 14 is additionally provided at the bending plate 2. It is worth noting that a square groove 8 is provided on the bending plate 2, and a bracket 10 is rotatably connected to the bending plate 2 through a rotating rod 9, and a screw 12 is threadedly connected to the bracket 10 through a threaded hole 11, and an operating wheel 13 is fixed to one end of the screw 12, and a positioning pressure ring 14 is rotatably connected to the other end of the screw 12, and a handle 18 is fixed to the bracket 10, and the bracket 10 can be rotated and flipped along the axis of the rotating rod 9 by pulling the handle 18;

[0066] It should be noted that when it is necessary to further increase the compression and positioning of the sole, by pulling the handle 18, the bracket 10 can be effectively driven to flip. In this process, it is ensured that the angle between the bracket 10 and the bending plate 2 is set at a right angle. In order to ensure the accuracy of the test, when the operating wheel 13 is turned, the positioning pressure ring 14 will press the sole, and cooperate with the clamping unit to form a two-way positioning purpose for the heel and the sole of the sole, thereby ensuring that the sole will not be displaced or offset when the sole is bent. This can avoid the situation that affects the final test results, and can significantly improve the evaluation results of the sole's bending resistance performance, making the evaluation results more accurate and reliable.

[0067] In this solution, when the sole needs to be bent, the working principle of the sole bending detection is as follows:

[0068] First, the sole is placed on the load-bearing plate 1 and the bending plate 2, and the rod body 403 is moved synchronously by the drive of the cylinder 402, driving the rubber pressure ring 404 to move synchronously, and the rubber pressure ring 404 forms a compression state on the sole, and by rotating the threaded knob 408, the threaded transmission effect between the threaded knob 408 and the threaded groove 407 is utilized to make the connecting ring 405 move downward after being stressed, thereby compressing the first spring 406, and then improving the compression effect when positioning the sole, and by pulling the handle 18 to flip the bracket 10 to rotate, the bracket 10 is flipped along the axis of the rotating rod 9 after being stressed, until the angle between the bracket 10 and the bending plate 2 is vertical, and by rotating the operating wheel 13, the screw rod 12 is rotated synchronously, and the threaded transmission effect between the screw rod 12 and the threaded hole 11 can be used to drive the positioning pressure ring 14 to move, and the positioning pressure ring 14 applies pressure to the sole to further strengthen the positioning of the sole;

[0069] Secondly, the servo motor 503 drives the rotating wheel 504 to rotate synchronously, and the first connecting rod 505 drives the bending plate 2 to swing back and forth along the axis of the hollow shaft 501 after receiving force, thereby driving the sole to bend back and forth synchronously. By simulating the bending of the sole during walking, running and other actions of the human foot, the bending resistance of the sole is evaluated to ensure that the footwear product can meet the needs of consumers during actual use;

[0070] Then, when the bending plate 2 swings, it drives the toothed plate 6014 to move synchronously, and the meshing transmission effect between the toothed plate 6014 and the spur gear 6013 is used to make the rotating shaft 601 rotate synchronously, driving the worm 603 to rotate synchronously, and the meshing transmission effect between the worm 603 and the worm wheel 606 is used to drive the transmission shaft 605 to rotate synchronously, and then drive multiple cams 607 to rotate synchronously, and the elastic effect of the second spring 6012 is used to ensure that the pressure plate 6010 is always in a fit state with the cam 607. Under the extrusion transmission force of the cam 607 and the pressure plate 6010, the pressure plate 6010 is forced to move back and forth in the channel 609, thereby applying pressure to the bottom of the sole;

[0071] Finally, while the sole is bent, the second connecting rod 708 is set so that the sliding block 704 moves along the through groove 703 after being subjected to force, and then drives the friction plate 702 to move back and forth along the slide groove 701 synchronously. The friction plate 702 and the sole are repeatedly rubbed against each other to simulate the friction loss between the sole and the road surface when a person walks, and observe and record the changes in the sole, such as the time, position, length, etc. of cracks after wear, as well as the overall shape and performance after the test.

[0072] The cylinder 402 and the servo motor 503 can be purchased from the market and equipped with a separate power supply. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

[0073] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
