Description

Technical Field

[0001] This invention relates to the field of sports shoe manufacturing technology, and in particular to a flexural endurance testing machine for sports shoe production lines. Background Technology

[0002] In footwear production, ensuring good quality and durability is paramount. To evaluate the performance of athletic shoe materials and structures under repeated folding and bending conditions, a flexural endurance testing machine is needed. This machine simulates the folding and bending that shoes may experience during actual use, directly reflecting important performance characteristics such as the strength and toughness of the upper and sole, as well as the bonding strength of the upper, sole, and welt, and overall quality and durability. The results of the flexural endurance test directly affect the pass rate of the finished shoe. Existing flexural endurance testing machines can only simulate the bending of the shoe along its length during normal walking, and cannot simulate the deflection of the shoe along its length on uneven surfaces. Therefore, there is an urgent need for a flexural endurance testing machine for athletic shoe production lines that can simulate both bending and deflection. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1-3 This invention provides a flexural endurance testing machine for a sports shoe production line, comprising a base plate 1, a first placement plate 2 rotatably connected to the base plate 1, a first limiting component mounted on the first placement plate 2, a rotating seat 3 rotatably connected to the base plate 1, a second placement plate 4 fixedly connected to the rotating seat 3, and a second limiting component mounted on the second placement plate 4. The rotation axis 13 of the first placement plate 2 and the rotation axis 13 of the second placement plate 4 are parallel to each other. A motion component for controlling the rotation of the first placement plate 2 and the second placement plate 4 is mounted on the base plate 1. By setting the first placement plate 2 and the second placement plate 4 with different rotation directions, and fixing both ends of the sports shoe to the first placement plate 2 and the second placement plate 4 respectively by the first limiting component and the second limiting component, the motion component can switch as needed to drive the first placement plate 2 or the second placement plate 4 to move. When the first placement plate 2 is driven to move, the first placement plate 2 tilts, thereby bending the sports shoe in the length direction for a bending test. When the second placement plate 4 is driven to move, the second placement plate 4 deflects, thereby deflecting the sports shoe for a deflection test.

[0018] A further optimized solution includes a first limiting component comprising a support plate 5 fixedly connected to a first placement plate 2, a horizontal plate 6 fixedly connected to the support plate 5, a hydraulic cylinder 7 fixedly connected to the horizontal plate 6, and a pressure plate 8 fixedly connected to the telescopic end of the hydraulic cylinder 7. The hydraulic cylinder 7 drives the pressure plate 8 downward, causing it to move into the shoe and contact the sole, thus stabilizing it on the first placement plate 2. Furthermore, the linear motion of the plate structure driven by the hydraulic cylinder 7 is a conventional application of the hydraulic cylinder 7. The hydraulic cylinder 7 and related auxiliary equipment used in this application are all conventional existing technologies and will not be elaborated upon here.

[0019] A further optimized design includes a second limiting component comprising a support frame 9 fixedly connected to the second placement plate 4. An arc-shaped plate 10 is slidably connected within the support frame 9, and a rubber pad is fixedly connected to the bottom side of the arc-shaped plate 10. A threaded rod 11 is threadedly connected to the top wall of the support frame 9, with its bottom end penetrating the support frame 9 and rotatably engaging with the top surface of the arc-shaped plate 10. By driving the arc-shaped plate 10 downwards via the threaded rod 11, the toe of the athletic shoe can be limited, stabilizing it on the second placement plate 4.

[0020] Further optimization of the scheme: the motion component includes two support seats 12 fixedly connected to the base plate 1; a rotating shaft 13 is provided above the base plate 1, and the rotating shaft 13 slides through the two support seats 12; a cam 14 is fixedly connected to the rotating shaft 13, the cam 14 is located below the first placement plate 2 and is in contact with the first placement plate 2; a through hole 15 is provided on the rotating seat 3, the rotating shaft 13 passes through the through hole 15 and leaves a gap between it and the inner wall of the through hole 15; a connecting plate 16 is fixedly connected to the rotating shaft 13, the connecting plate 16 is located on the side of the rotating seat 3 away from the first placement plate 2, and several limiting rods 17 are fixedly connected to the side of the connecting plate 16 close to the rotating seat 3; several limiting holes 18 that are adapted to the limiting rods 17 are provided on the side wall of the rotating seat 3; an adjustment component for controlling the axial movement of the rotating shaft 13 and a control component for controlling the reciprocating rotation of the rotating shaft 13 are installed on the base plate 1. The reciprocating rotation of the rotating shaft 13 drives the cam 14 to reciprocate, causing one end of the first placement plate 2 to move up and down continuously, thus causing continuous deflection and continuous bending of the sports shoe.

[0021] Further optimization of the scheme: the adjustment component includes a vertical plate 19 fixedly connected to the base plate 1, with a threaded post 20 threaded through the vertical plate 19. The threaded post 20 is threadedly connected to the vertical plate 19, with one end of the threaded post 20 rotatably engaged with the rotating shaft 13, and the other end of the threaded post 20 fixedly connected to an adjustment knob 21. The adjustment knob 21 drives the threaded post 20 to rotate, thereby driving the rotating shaft 13 to move along its axial direction, thus adjusting the position of the cam 14 so that it can adjust the movement range of the first placement plate 2. At the same time, it can drive the limiting rod 17 on the connecting plate 16 to engage with the limiting hole 18, thereby driving the rotating seat 3 to swing back and forth, facilitating deflection testing.

[0022] A further optimized scheme includes a control component comprising a sleeve 22 located at the end of the rotating shaft 13 and fixedly connected to it; a rack 23 slidably connected to the base plate 1; and toothed grooves on the periphery of the sleeve 22 that mesh with the rack 23. A turntable 24 is rotatably connected to the base plate 1, and a connecting plate 25 is rotatably connected between the end face of the turntable 24 and the rack 23. A drive motor 26 is mounted at the bottom of the base plate 1 to drive the turntable 24 to rotate. The drive motor 26 drives the turntable 24 to rotate, which in turn pulls or pushes the rack 23 to reciprocate linearly via the connecting plate 25. During the movement, the rack 23 drives the sleeve 22 to rotate via the toothed grooves, thereby driving the rotating shaft 13 to reciprocate.

[0023] The design is further optimized by fixing a connecting seat 27 to the base plate 1. One end of the bottom surface of the first placement plate 2 is rotatably engaged with the connecting seat 27, and the cam 14 is located at the end of the bottom surface of the first placement plate 2 away from the connecting seat 27. By rotating the connecting seat 27 with one end of the first placement plate 2, the other end of the first placement plate 2 can be moved up and down by the cam 14 to rotate the first placement plate 2, thereby conducting a bending test on the sports shoe.

[0024] Further optimization involves an arc-shaped groove 28 on the base plate 1, within which a rotating seat 3 is rotatably mounted. The bottom wall of the arc-shaped groove 28 has several receiving slots 29, each containing a steel ball 30. The top of the steel ball 30 protrudes above the bottom surface of the arc-shaped groove 28, and a compression spring 31 is fixedly connected between the bottom of the steel ball 30 and the bottom wall of the receiving slot 29. The bottom surface of the rotating seat 3 has several spherical grooves corresponding to the steel ball 30. Under the action of the compression spring 31, the steel ball 30 engages with the spherical grooves, ensuring that during the bending test of the first placement plate 2, the second placement plate 4 will not rotate along the axis of the rotating shaft 13.

[0025] The working process of this invention is as follows: In use, the sports shoe is placed on the first placement plate 2 and the second placement plate 4. Then, the hydraulic cylinder 7 is activated, which drives the pressure plate 8 to move downward, so that the pressure plate 8 moves into the shoe and presses the sole tightly. At the same time, the threaded rod 11 is rotated, which drives the arc plate 10 to move downward, pressing the top of the sports shoe tightly. The drive motor 26 is activated, which drives the turntable 24 to rotate. Then, the connecting plate 25 pushes or pulls the rack 23 to make reciprocating linear motion. Then, the rack 23 drives the sleeve 22 and the rotating shaft 13 to swing back and forth. The rotating shaft 13 drives the cam 14 to swing back and forth, thereby continuously lifting the first placement plate 2 and causing the second placement plate 2 to rotate, thus performing a continuous bending test on the sports shoe. By rotating the adjustment knob 21, the threaded column 20 is rotated, which in turn drives the motion shaft 13 to move along the axial direction, thereby adjusting the contact position between the cam 14 and the first placement plate 2, thus changing the movement amplitude of the first placement plate 2. Similarly, by adjusting the knob 21, the motion shaft 13 is driven to move along the axial direction, which allows the limiting rod 17 on the connecting plate 16 to be inserted into the limiting hole 18. At this time, the cam 14 is separated from the first placement plate 2. During the reciprocating swing, the motion shaft 13 will drive the rotating seat 3 to swing back and forth through the connecting plate 16, thereby driving the second placement plate 4 to swing along the axial direction of the motion shaft 13, and performing a deflection test on the sports shoe.
