Description

Technical Field

[0001] This utility model belongs to the field of shoe sole flexural endurance testing technology, and in particular relates to a shoe sole flexural endurance testing machine. Background Technology

[0002] The sole is the part of the shoe that contacts the ground. It has functions such as anti-slip, wear resistance, cushioning, rebound, and support stability. Flexural resistance is one of the important indicators for measuring the quality of footwear products. Therefore, during the shoe manufacturing process, a flexural resistance tester is needed to conduct flexural resistance tests on the sole to evaluate its durability and reliability in actual use.

[0003] A shoe sole flexural endurance testing machine, as disclosed in utility model patent application CN207798578U, includes two shoe sole support frames and a bending movable frame, with the bending movable frame located between the two shoe sole support frames. Each shoe sole support frame includes a bottom guide rail, a bottom support slider, and a bracket. One end of the bracket is fixed to the bottom support slider, and the other end is provided with a fixed clamping block and a movable clamping block. The bending movable frame includes an upper moving guide rail, a lower moving guide rail, an upper slider, a lower slider, and a shoe sole clamping body. The shoe sole clamping body includes two limiting cylinders. This utility model strengthens the fixation of the shoe sole, facilitates control of the bending process during shoe sole flexural endurance testing, and allows for flexural endurance testing on both sides of the shoe sole. It can also perform flexural endurance testing on shoe soles of various thicknesses, has strong applicability, and ensures the accuracy of flexural endurance testing. However, in the application of this technical solution, the sole is fixed at both ends and folded in the middle to conduct a flexural resistance test. The bending deformation of the sole caused by this test method is different from the bending deformation of the sole when a person walks normally. This has the technical problem that the sole cannot be effectively tested for flexural resistance according to the actual situation, and the test results are not accurate. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a shoe sole flexural endurance testing machine, which can effectively solve the problems of the existing technology.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4As shown, this utility model is a shoe sole flexural endurance testing machine, including a frame 1, and further including: a groove 2 located near the middle of the bottom inner side of the frame 1; a U-shaped positioning groove 9 located on one side of the top of the frame 1, with rounded corners at the inner edge of the positioning groove 9; three sets of positioning grooves 9 arranged at equal intervals on one side of the top of the frame 1; an anti-slip pad 16 located at the bottom inner side of the positioning groove 9; a servo motor 3 located at the top of the front end of the groove 2; a drive shaft 13 located at the top of the front inner side of the groove 2, with the front end of the drive shaft 13 passing through the front inner side of the groove 2 and connected to the output end of the servo motor 3; a linkage shaft 14 rotatably connected to the top of the rear inner side of the groove 2; the drive shaft 13 and the linkage shaft 14 symmetrically arranged on the inner side of the groove 2; and a swing arm 8 located on the inner side of the drive shaft 13 and the linkage shaft 14, parallel to the groove. On the inner side, a bending rod 10 is provided at one end between the swing arms 8. The bending rod 10 is parallel to the top surface of the frame 1. When the test is carried out, the sole of the shoe to be tested for flexural strength is fixed inside the positioning groove 9, and then the servo motor 3 is started to drive the drive shaft 13 to rotate counterclockwise, which in turn drives the swing arms 8 and the bending rod 10 to rotate counterclockwise. Thus, the bending rod 10 bends the sole from bottom to top. After the sole is bent to the minimum angle, the servo motor 3 drives the drive shaft 13 to drive the swing arms 8 and the bending rod 10 to rotate back to their original positions, so that the sole is reset. This process is repeated to carry out the sole flexural strength test. The bending rod 10 is provided with a first rubber sleeve 7. The first rubber sleeve 7 increases the friction between the bending rod 10 and the sole and provides padding for the sole, thus fully simulating the bending state of the sole when walking, achieving the purpose of scientifically and effectively conducting the sole flexural strength test.

[0024] In use, the servo motor 3 drives the drive shaft 13 to drive the adjusting swing arm 8 downward, thereby adjusting the bending rod 10 to the inside of the frame 1. After fixing the sole to be tested for flexural strength in the positioning groove 9, the servo motor 3 drives the drive shaft 13 to rotate counterclockwise and drive the swing arm 8 and the bending rod 10 to rotate counterclockwise. The bending rod 10 bends the sole from bottom to top. After bending the sole to the minimum angle, the servo motor 3 drives the drive shaft 13 to drive the swing arm 8 and the bending rod 10 to rotate back to reset, so that the sole is reset. This process is repeated to simulate the bending state of the sole when walking and to conduct a sole flexural strength test.

[0025] As a further implementation of this embodiment, such as Figure 1-4As shown, a limiting component is provided on the top of the frame 1. The limiting component includes a clamping electric cylinder 4, which is located at the middle position on one side of the bottom of the inner side of the frame 1. A through hole 15 is provided at the middle position on one side of the top of the inner side of the frame 1. A lifting seat 6 is provided on the top of the frame 1. The top of the clamping electric cylinder 4 passes through the interior of the through hole 15 and is fixedly connected to the middle position of the bottom of the lifting seat 6. A connecting groove 5 is provided on one side of the lifting seat 6. A fixing pressure rod 11 is provided on one side between the two ends inside the connecting groove 5. The pressure rod 11 is parallel to the top surface of the frame 1. After the shoe sole is placed inside the positioning groove 9, the clamping electric cylinder 4 is activated to drive the lifting seat 6 to descend, and drive the fixed pressure rod 11 to descend through the connecting groove 5 to achieve the purpose of clamping and fixing the shoe sole inside the positioning groove 9. The fixed pressure rod 11 is provided with a second rubber sleeve 12. The cylindrical fixed pressure rod 11 and the second rubber sleeve 12 provided on its outside can clamp and stabilize the shoe sole without wearing the shoe sole during the flexural endurance test, and can be used to clamp shoe soles of different thicknesses.

[0026] Working principle: When using the testing machine, firstly, the servo motor 3 drives the drive shaft 13 to move the adjusting arm 8 downward, thereby adjusting the bending rod 10 to the inside of the frame 1. Then, the shoe sole to be tested for flexural strength is placed inside the positioning groove 9, and the clamping cylinder 4 is activated to lower the lifting seat 6, which in turn lowers the fixing pressure rod 11 through the connecting groove 5, pressing and fixing the shoe soles of different thicknesses inside the positioning groove 9. The cylindrical fixing pressure rod 11 and the second rubber sleeve 12 on its outside can press and stabilize the shoe sole and prevent wear during the flexural strength test. After fixing the sole to be tested for flexural strength in the positioning groove 9, the servo motor 3 drives the drive shaft 13 to rotate counterclockwise, which in turn drives the swing arm 8 and the bending rod 10 to rotate counterclockwise. The bending rod 10 bends the sole from bottom to top, and the anti-slip pad 16 prevents the sole from slipping out of the positioning groove 9. After the sole is bent to the minimum angle, the servo motor 3 drives the drive shaft 13 to rotate the swing arm 8 and the bending rod 10 back to their original position, so that the sole is reset. This process is repeated to simulate the bending state of the sole when walking and to conduct the sole flexural strength test.
