A garment water resistance tester

Abstract

This application discloses a garment water-permeability tester, belonging to the technical field of garment hydrostatic pressure testing equipment. It includes a test platform, a drive mechanism, a testing mechanism, an anti-sway mechanism, a drainage mechanism, and a sealing mechanism. The design is novel and the device ingenious. By setting up a drive mechanism, the upper and lower clamping platforms are pressed together. When the pressure on the upper clamping platform reaches the pressure value set by the pressure sensor, the pressure sensor feeds a signal back to the PLC controller, which then shuts down the drive motor. After the test is completed, the PLC controller restarts the drive mechanism, causing the upper clamping platform to move upwards. The tested garment is then removed from the lower clamping platform. The entire process eliminates the need for manual control of the upper clamping platform's movement, avoiding excessive hand fatigue during prolonged testing. This also improves testing progress and work efficiency, greatly enhancing the practicality of the device.

Description

Technical Field

[0001] This application relates to the technical field of hydrostatic pressure testing equipment for clothing, and in particular to a tester for the water resistance performance of clothing. Background Technology

[0002] Currently, waterproof clothing is widely used in outdoor sports, special operations and other fields. Its waterproof performance is mainly achieved through local heat sealing process. As consumers' requirements for the waterproof performance of clothing increase, the demand for waterproof performance testing in the production process is growing. In the existing technology, waterproof performance testing mostly adopts the overall immersion method or manual spraying method, but these methods cannot accurately simulate the water pressure environment in actual use, and it is especially difficult to detect water seepage in the local heat-sealed area.

[0003] In recent years, with the development of materials science, new waterproof fabrics have emerged one after another. However, the reliability testing methods for heat sealing processes have not been updated in sync, resulting in some waterproof garments experiencing localized water seepage problems in actual use. Therefore, a garment water-resistant performance tester has appeared on the market.

[0004] However, in existing garment water resistance testers, the upper clamping platform needs to be manually moved up and down during the testing process. This is not only time-consuming and labor-intensive, but also reduces work efficiency and affects the testing progress. In addition, the upper clamping platform will shake when it moves down, which will affect the pressing accuracy between the upper and lower clamping platforms. When the pressing is deviated, it will affect the sealing between the two and cause water leakage.

[0005] Therefore, this application proposes a tester for the water resistance performance of clothing. Utility Model Content

[0006] This application proposes a garment water-resistant performance tester to solve the problems mentioned in the background art. By setting a drive mechanism, the upper and lower clamping platforms are pressed together under the action of the drive mechanism. When the pressure of the upper clamping platform reaches the pressure value set by the pressure sensor, the pressure sensor feeds back the signal to the PLC controller, and the PLC controller shuts down the drive motor. After the test is completed, the PLC controller restarts the drive mechanism, which moves the upper clamping platform up and down, and then the tested garment is taken out from the lower clamping platform. The entire process does not require manual control of the up and down movement of the upper clamping platform, avoiding excessive hand fatigue during long-term testing, while improving the testing progress and work efficiency, and greatly enhancing the practicality of the device.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A garment water-resistant performance tester includes a test platform, a drive mechanism, a detection mechanism, an anti-sway mechanism, a drainage mechanism, and a sealing mechanism. The detection mechanism includes an upper clamping platform, a lower clamping platform, a water inlet, and a water outlet. The lower clamping platform is disposed on the test platform, and the upper clamping platform is disposed above the lower clamping platform. The lower clamping platform is provided with a water inlet and a water outlet inside. The upper clamping platform is automatically pressed together with the lower clamping platform by the drive mechanism.

[0009] In a preferred embodiment, the driving mechanism includes a drive motor, a screw, a sleeve, and a pressure sensor. The drive motor is fixedly connected to the test bench and electrically connected to an external PLC controller. The screw is rotatably connected inside the test bench, and the top end of the screw is fixedly connected to the output end of the drive motor. The sleeve is threadedly connected to the outside of the screw, and the bottom end of the sleeve is fixedly connected to the top of the upper clamping platform.

[0010] The drive motor is started by the PLC controller, which in turn drives the screw to rotate. When the screw rotates, it causes the sleeve to move down, causing the upper clamping platform to press against the lower clamping platform, thereby improving the practicality of the device.

[0011] In a preferred embodiment, a pressure sensor is installed inside the test bench and below the lower clamping platform, and the pressure sensor is electrically connected to an external PLC controller;

[0012] When the pressure from the upper clamp reaches the pressure value set by the pressure sensor, the pressure sensor sends a signal back to the PLC controller, which then automatically shuts down the drive motor, thereby improving the practicality of the device.

[0013] In a preferred embodiment, the anti-sway mechanism includes guide posts and guide holes. Each guide hole is opened inside the upper clamping platform, and a guide post is slidably connected inside each guide hole. The top end of each guide post is fixedly connected to the test platform.

[0014] By setting an anti-sway mechanism, when the upper clamping platform moves downward, it will move downward along the guide column through the guide hole, preventing the upper clamping platform from shaking during the downward movement, thereby improving the pressing accuracy of the upper and lower clamping platforms and enhancing the practicality of the device.

[0015] In a preferred embodiment, the drainage mechanism includes a drainage trough and a drainage channel. The drainage trough is located inside the test bench and outside the lower clamping platform. The test bench is provided with a drainage channel, which communicates with the drainage trough and the water outlet.

[0016] By setting up a drainage mechanism, excess water in the lower clamping platform will enter the drainage tank during the test, flow to the water outlet through the drainage channel, and be discharged through the water outlet, thereby preventing excess water from leaking out of the lower clamping platform, thus improving the sealing performance of the testing mechanism and enhancing the practicality of the device.

[0017] In a preferred embodiment, the sealing mechanism includes a sealing block one and a sealing block two. The sealing block one is fixedly connected to the bottom of the upper clamping platform, and the sealing block two is fixedly connected to the top of the test platform and outside the drainage groove.

[0018] By setting a sealing mechanism, a sealing block one is set on the upper clamping platform and a sealing block two is set on the outside of the lower clamping platform. When the upper clamping platform and the lower clamping platform are pressed together, the sealing block one and the sealing block two will come into contact with the surface of the garment to prevent moisture leakage and improve the sealing effect, thereby enhancing the practicality of the device.

[0019] The beneficial effects of this application are:

[0020] 1. This garment water-resistant performance tester is equipped with a drive mechanism. Under the action of the drive mechanism, the upper clamping platform and the lower clamping platform are pressed together. When the pressure of the upper clamping platform reaches the pressure value set by the pressure sensor, the pressure sensor feeds back the signal to the PLC controller. The PLC controller then shuts down the drive motor. After the test is completed, the PLC controller restarts the drive mechanism to move the upper clamping platform up. Then the tested garment is taken out from the lower clamping platform. The entire process does not require manual control of the up and down movement of the upper clamping platform, avoiding excessive hand fatigue during long-term testing. At the same time, it improves the testing progress and work efficiency, and greatly enhances the practicality of the device.

[0021] 2. This garment water-resistant performance tester incorporates an anti-sway mechanism. When the upper clamping platform moves downward, it moves directionally along the guide column through the guide hole, preventing swaying during the downward movement and thus improving the pressing accuracy between the upper and lower clamping platforms. Furthermore, a drainage mechanism is incorporated, allowing excess water in the lower clamping platform to enter the drainage trough during testing. This water then flows through the drainage channel to the outlet hole and is discharged, preventing excess water from leaking out of the lower clamping platform. This enhances the sealing performance of the testing mechanism and significantly improves the practicality of the device. Attached Figure Description

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-4 A garment water-resistant performance tester includes a test platform 1, a drive mechanism 2, a detection mechanism 3, an anti-sway mechanism 4, a drainage mechanism 5, and a sealing mechanism 6. The detection mechanism 3 includes an upper clamping platform 31, a lower clamping platform 32, a water inlet 33, and a water outlet 34. The lower clamping platform 32 is set on the test platform 1, and the upper clamping platform 31 is set above the lower clamping platform 32. The lower clamping platform 32 has a water inlet 33 and a water outlet 34 inside. The upper clamping platform 31 is automatically pressed together with the lower clamping platform 32 by the drive mechanism 2.

[0029] Reference Figure 1-4 The drive mechanism 2 includes a drive motor 21, a screw 22, a sleeve 23, and a pressure sensor 24. The drive motor 21 is fixedly connected to the test bench 1 and is electrically connected to an external PLC controller. The screw 22 is rotatably connected inside the test bench 1, and the top end of the screw 22 is fixedly connected to the output end of the drive motor 21. The sleeve 23 is threadedly connected to the outside of the screw 22, and the bottom end of the sleeve 23 is fixedly connected to the top of the upper clamping platform 31. When the drive motor 21 is started by the PLC controller, the drive motor 21 will drive the screw 22 to start rotating. When the screw 22 rotates, it will cause the sleeve 23 to move down, so that the upper clamping platform 31 and the lower clamping platform 32 are pressed together, thereby improving the practicality of the device.

[0030] Reference Figure 1-4 A pressure sensor 24 is installed inside the test bench 1 and below the lower clamping platform 32. The pressure sensor 24 is electrically connected to an external PLC controller. When the pressure of the upper clamping platform 31 reaches the pressure value set by the pressure sensor 24, the pressure sensor 24 feeds back the signal to the PLC controller, and the PLC controller will automatically shut down the drive motor 21, thereby improving the practicality of the device.

[0031] Reference Figure 1-3 The anti-sway mechanism 4 includes guide posts 41 and guide holes 42. Each guide hole 42 is opened inside the upper clamping platform 31, and a guide post 41 is slidably connected inside each guide hole 42. The top of each guide post 41 is fixedly connected to the test platform 1. By setting the anti-sway mechanism 4, when the upper clamping platform 31 moves down, the upper clamping platform 31 will move downward along the guide post 41 through the guide hole 42, preventing the upper clamping platform 31 from shaking during the downward movement. This improves the pressing accuracy between the upper clamping platform 31 and the lower clamping platform 32, thereby enhancing the practicality of the device.

[0032] Reference Figure 1-4 The drainage mechanism 5 includes a drainage trough 51 and a drainage channel 52. The drainage trough 51 is located inside the test platform 1 and outside the lower clamping platform 32. The drainage channel 52 is provided inside the test platform 1 and is connected to the drainage trough 51 and the water outlet 34. By setting up the drainage mechanism 5, during the test, excess water in the lower clamping platform 32 will enter the drainage trough 51, flow through the drainage channel 52 to the water outlet 34, and be discharged through the water outlet 34, thereby preventing excess water from leaking out of the lower clamping platform 32, thereby improving the sealing performance of the testing mechanism 3 and enhancing the practicality of the device.

[0033] Reference Figure 1-4 The sealing mechanism 6 includes a first sealing block 61 and a second sealing block 62. The first sealing block 61 is fixedly connected to the bottom of the upper clamping platform 31, and the second sealing block 62 is fixedly connected to the top of the test platform 1 and outside the drainage groove 51. By setting the sealing mechanism 6, the first sealing block 61 is set on the upper clamping platform 31 and the second sealing block 62 is set on the outside of the lower clamping platform 32. When the upper clamping platform 31 and the lower clamping platform 32 are pressed together, the first sealing block 61 and the second sealing block 62 will come into contact with the surface of the garment to prevent moisture leakage and improve the sealing effect, thereby improving the practicality of the device.

[0034] Working principle: The garment to be tested is placed on the lower clamping platform 32. Then, the drive motor 21 is started by the PLC controller, which drives the screw 22 to rotate. When the screw 22 rotates, it causes the sleeve 23 to move down, so that the upper clamping platform 31 and the lower clamping platform 32 are pressed together. When the pressure of the upper clamping platform 31 reaches the pressure value set by the pressure sensor 24, the pressure sensor 24 feeds back the signal to the PLC controller, which then shuts down the drive motor 21. The external pressure pump is connected through the water inlet 33, and external water flows into the lower clamping platform 32 through the water inlet 33. When a certain capacity pressure is reached, observe whether there is any water leakage in the garment. After the test is completed, the drive mechanism 2 is started again by the PLC controller, which moves the upper clamping platform 31 upward. Then, the tested garment is taken out from the lower clamping platform 32. The entire process does not require manual control of the up and down movement of the upper clamping platform 31, avoiding excessive hand fatigue during long-term testing, and improving the testing progress and work efficiency.

[0035] By setting the anti-sway mechanism 4, when the upper clamping platform 31 moves down, the upper clamping platform 31 will move downward along the guide post 41 through the guide hole 42, preventing the upper clamping platform 31 from shaking during the downward movement, thereby improving the pressing accuracy of the upper clamping platform 31 and the lower clamping platform 32.

[0036] By setting up a drainage mechanism 5, during the test, excess water in the lower clamping platform 32 will enter the drainage trough 51, flow through the drainage channel 52 to the water outlet 34, and be discharged through the water outlet 34, thereby preventing excess water from leaking out of the lower clamping platform 32 and improving the sealing performance of the testing mechanism 3.

[0037] By setting a sealing mechanism 6, a sealing block 61 is set on the upper clamping platform 31 and a sealing block 62 is set on the outside of the lower clamping platform 32. When the upper clamping platform 31 and the lower clamping platform 32 are pressed together, the sealing block 61 and the sealing block 62 will come into contact with the surface of the garment to prevent moisture from leaking out and improve the sealing effect.

[0038] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
