[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] This utility model provides a technical solution: such as Figure 1-5 As shown, a shoe upper breathability testing device includes a testing box 1, a drying box 5 is fixedly installed on the side of the testing box 1, the bottom of the drying box 5 is connected to the testing box 1 through a return pipe 7, and multiple activated carbon plates 24 and dust filter plates 25 are detachably installed inside the drying box 5.

[0024] Multiple activated carbon plates 24 and dust filter plates 25 can effectively filter air and water molecules in the test chamber 1, and prevent dust from blowing onto the shoe upper fabric and affecting the breathability test. The reflux pipe 7 can realize the internal circulation of the test air in the test chamber 1, thereby reducing the impact of external humid air on the test results.

[0025] A workbench 9 is fixedly installed on the bottom wall of the testing box 1. Clamping mechanisms are installed at both ends of the top surface of the workbench 9. A moving frame 10 is slidably connected to the top surface of the workbench 9. A moving mechanism is installed inside the testing box 1, and the moving mechanism drives the moving frame 10 to slide. Multiple wind speed sensors 19 are installed on the moving frame 10. Multiple second electric telescopic rods 20 are symmetrically installed on the bottom surface of the moving frame 10. A connecting seat 21 is installed at the bottom end of the multiple second electric telescopic rods 20. Multiple nozzles 22 are fixedly connected to the bottom surface of the connecting seat 21. A fan 13 is fixedly installed on the top wall of the testing box 1. The fan 13 is connected to the drying box 5 through the air inlet pipe 8. The exhaust end of the fan 13 is connected to the connecting seat 21.

[0026] The movable frame 10 can be moved by the movable mechanism, so that the wind speed sensor 19 and the nozzle 22 can slide synchronously, thereby enabling the air permeability of the fabric to be detected at different locations. The setting of multiple wind speed sensors 19 and nozzles 22 makes it easy for staff to compare the results.

[0027] Furthermore, the moving mechanism includes a drive motor 4, which is fixedly installed on the outside of the detection box 1. The output shaft of the drive motor 4 is connected to a threaded rod 11, and the other end of the threaded rod 11 is rotatably connected to the side wall of the detection box 1. The threaded rod 11 is threadedly connected to the moving frame 10. Limiting rods 12 are installed on both inner walls of the detection box 1, and the moving frame 10 is slidably connected to the limiting rods 12. The rotation of the moving frame 10 can be restricted by the limiting rods 12, so that it can only move linearly.

[0028] Furthermore, each clamping mechanism includes an L-shaped plate 14, and each L-shaped plate 14 is fixedly installed on the top surface of the workbench 9. Two first electric telescopic rods 15 are symmetrically installed on the top surface of each L-shaped plate 14. A pressure plate 16 is installed at the bottom end of each pair of first electric telescopic rods 15 located on the same side, which facilitates clamping the shoe upper fabric.

[0029] Furthermore, multiple guide rods 18 are installed on both inner sides of the workbench 9, and each guide rod 18 is slidably connected to the moving frame 10. Movable slots 17 are provided on both outer sides of the workbench 9, and the moving frame 10 is movably connected in the two movable slots 17, providing the moving stability of the moving frame 10.

[0030] Furthermore, multiple guide rails 23 are fixedly installed on the inner walls of both sides of the drying oven 5, and both ends of each activated carbon plate 24 and dust filter plate 25 are slidably connected in the corresponding guide rail 23 for easy disassembly.

[0031] Furthermore, two first sealing doors 2 are symmetrically rotatably connected to the outside of the testing chamber 1, and a viewing window 3 is installed on the outside of each first sealing door 2. A second sealing door 6 is rotatably connected to the outside of the drying chamber 5. It should be noted that the first sealing door 2 and the second sealing door 6 are both limited by external locking devices, and sealing strips can be added to the sides of the first sealing door 2 and the second sealing door 6 to improve sealing performance.

[0032] This utility model provides a shoe upper breathability testing device, the specific working principle of which is as follows: First, place both ends of the shoe upper fabric under the pressure plate 16 respectively, then start the first electric telescopic rod 15 to drive the pressure plate 16 to slowly press down, firmly clamping the shoe upper fabric on the worktable 9, ensuring the stability of the fabric position during the testing process;

[0033] Next, close the first sealing door 2 and the second sealing door 6, fix them with an external locking device, and further improve the sealing of the test chamber 1 and the drying chamber 5 with a sealing strip to prevent outside air from interfering with the test results;

[0034] Then the fan 13 is started. After the air is purified and dried by the activated carbon plate 24 and the dust filter plate 25 in the drying box 5, it enters the fan 13 through the air inlet pipe 8 and is then transported by the fan 13 to the connecting seat 21. It is then sprayed evenly onto the shoe surface at a constant wind speed through the nozzle 22.

[0035] At the same time, the drive motor 4 starts to work, driving the threaded rod 11 to rotate. Due to the limitation of the limit rod 12, the moving frame 10 can only move linearly along the direction of the threaded rod 11. The wind speed sensor 19 on it slides synchronously with the nozzle 22, which facilitates comparative detection of different positions of the shoe upper fabric.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
