Description

Technical Field

[0001] This utility model relates to the field of footwear testing technology, and in particular to a footwear stretch testing machine with bidirectional stretch function. Background Technology

[0002] During daily use, shoes are constantly subjected to various stretching forces, such as walking, running, and jumping, which cause the soles and uppers to stretch and deform. To ensure the quality and durability of shoes, it is necessary to conduct stretch performance tests to simulate the stretching and contraction conditions in actual use and to detect whether problems such as damage, glue separation, or cracking will occur during the stretching and contraction process.

[0003] Most existing shoe stretchability testing machines can only perform unidirectional stretchability testing, meaning they can only apply stretching force to the shoe in one direction. However, in actual use, the stretching force on the shoe is multidirectional. Unidirectional stretchability testing cannot comprehensively and accurately simulate the actual use of the shoe, resulting in certain limitations in the test results, which cannot truly reflect the shoe's stretchability and quality. Utility Model Content

[0004] The purpose of this application is to provide a shoe stretch testing machine with bidirectional stretch function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a shoe stretch testing machine with bidirectional stretch function, including a base; A shoe mounting platform that slides along a top groove of the base; The first driving device is used to drive the shoe fixing platform to slide; The sole fixing mechanism is installed on the shoe fixing platform to clamp and fix the sole; A vertical plate is fixed to the top of the base, and a horizontal tension gauge is fixedly installed on one side near the bottom. A horizontal fixing clip for clamping the end of the shoe is fixedly connected to the horizontal tension gauge. A sliding plate is slidably connected to the vertical plate along the vertical direction of the vertical plate. A longitudinal tension gauge is fixedly connected to the bottom of the sliding plate, and a longitudinal fixing clamp is fixedly connected to the bottom end of the longitudinal tension gauge. The second driving device is mounted on the upright plate to drive the sliding plate to slide.

[0006] Preferably, the first driving device includes a first motor and a first lead screw fixed to the output end of the first motor. The first motor is fixed on the base and the shoe fixing platform and the first lead screw are threadedly connected.

[0007] Preferably, the second drive device includes a second motor and a second lead screw fixed to the output end of the second motor, the first motor is fixed to the vertical plate and the sliding plate and the second lead screw are threadedly connected.

[0008] Preferably, the sole fixing mechanism includes a flip motor and a clamping plate. The sole fixing mechanism has two symmetrically arranged on the shoe fixing platform. The flip motor and the shoe fixing platform are fixedly connected. The output end of the flip motor drives the clamping plate.

[0009] Preferably, a protective rubber strip is fixedly connected to the end of the clamping plate along its length.

[0010] Preferably, the flipping motor, the first motor, and the second motor are controlled by a controller, which is electrically connected to the first tension gauge and the second tension gauge.

[0011] In summary, the technical effects and advantages of this utility model are as follows: Bidirectional stretch test: The shoe fixing platform and sliding plate are driven by the first and second driving devices to slide in the horizontal and vertical directions respectively, realizing the test of the bidirectional stretch performance of the shoe. This more comprehensively simulates the stress situation of the shoe in actual use and improves the accuracy and reliability of the test results.

[0012] Securely fasten the shoe: The sole fixing mechanism uses a flip motor to drive clamps to hold and fix the sole, and the ends of the clamps are equipped with protective rubber strips, which not only securely fasten the shoe but also prevent damage to the sole. Lateral and longitudinal fixing clamps further secure the ends of the shoe, ensuring its stability during testing.

[0013] Precise measurement of stretch force: The horizontal and vertical tension gauges accurately measure the stretch force on the shoe in the horizontal and vertical directions, respectively, and feed the data back to the controller, providing accurate data support for the research and development and improvement of footwear products.

[0014] Automated control: The controller provides unified control over the first motor, the second motor, and the tilting motor. Operators can preset test parameters as needed to achieve automated testing, which improves testing efficiency and ease of operation. Attached Figure Description

Next, fix the first motor 6 of the first drive device onto the base 1, connect the first lead screw 7 to the output end of the first motor 6, and simultaneously thread the first lead screw 7 to the shoe mounting platform 2.

[0023] Fix the upright plate 8 to the top of the base 1, and install the horizontal tension gauge 9 and the transverse fixing clamp 10. Install the sliding plate 13 in the vertical direction of the upright plate 8 so that it can slide along the upright plate 8, and install the longitudinal tension gauge 14 and the longitudinal fixing clamp 15. Fix the second motor 11 of the second drive device to the upright plate 8, connect the second lead screw 12 to the output end of the second motor 11, and thread the second lead screw 12 to the sliding plate 13.

[0024] Install the sole fixing mechanism 3, fix the flip motor 5 on the shoe fixing platform 2, connect the clamping plate 4 to the output end of the flip motor 5, and install the protective rubber strip 16 on the end of the clamping plate 4. Finally, connect the controller to the first motor 6, the second motor 11, the flip motor 5, the horizontal tension gauge 9, and the longitudinal tension gauge 14, perform power-on debugging, and check the operation of each component and the measurement accuracy of the tension gauge.

[0025] Testing process Secure the shoe: Place the shoe to be tested on the shoe mounting platform 2, start the flip motor 5 to drive the clamping plate 4 to rotate and clamp the sole. At the same time, use the horizontal fixing clamp 10 to clamp the end of the shoe and use the vertical fixing clamp 15 to fix the corresponding parts of the shoe.

[0026] Set test parameters: Set test parameters through the controller, such as horizontal telescopic distance, vertical telescopic distance, telescopic speed, and number of telescopic operations.

[0027] Test begins: The first motor 6 and the second motor 11 are activated. The first motor 6 drives the first lead screw 7 to rotate, causing the shoe mounting platform 2 to slide along the groove at the top of the base 1, applying a horizontal stretching force to the shoe. The second motor 11 drives the second lead screw 12 to rotate, causing the sliding plate 13 to slide along the vertical direction of the upright plate 8, applying a vertical stretching force to the shoe. The horizontal tension gauge 9 and the vertical tension gauge 14 measure the stretching forces exerted on the shoe in the horizontal and vertical directions, respectively, and feed the data back to the controller.

[0028] Data recording and analysis: The controller records the stretching force data fed back by the horizontal tension gauge 9 and the longitudinal tension gauge 14 during each stretching process. After the test, the data is analyzed to evaluate the bidirectional stretching performance of the shoe.

[0029] Maintenance and care Regularly clean the testing machine, removing dust and debris from the base 1, slide, and upright plate 8. Inspect the transmission components of the first and second drive devices, such as lead screws and nuts, and replace them promptly if worn. Regularly calibrate the horizontal tension gauge 9 and the longitudinal tension gauge 14 to ensure the accuracy of the measurement data.
