Description

Technical Field

[0001] This invention relates to the field of material aging testing technology, and in particular to an aging testing device for waterproof adhesive strips on sportswear. Background Technology

[0002] In sportswear, especially in the outdoor and professional sports fields, hot-pressed waterproof adhesive strips are widely used to seal seams to achieve the core functions of waterproofing and windproofing. To ensure product durability, it is crucial to conduct rigorous aging tests on newly developed adhesive strip materials (such as thermoplastic polyurethane film adhesive strips). Currently, the mainstream aging test for waterproof adhesive strips usually involves pressing the adhesive strip to be tested onto a specified sportswear fabric substrate to form a test sample. The sample is then placed in an aging test machine that simulates harsh environmental conditions for a specific period of time. After the test, the sample is removed, and the adhesive strip is carefully observed and evaluated by visual inspection or with the aid of instruments to determine whether it exhibits failure phenomena such as cracking, powdering, stickiness, blistering, discoloration, shrinkage, embrittlement, and most importantly, detachment from the substrate (such as peeling off from the fabric edge or completely falling off).

[0003] However, each test can usually only complete the aging process of a single sample or a single strip of adhesive. After completing one aging and observation evaluation, if the next batch or new adhesive strip needs to be tested, the aged sample must first be removed from the test fixture, then manually cut and reinstalled, and the new fabric and adhesive strip to be tested must be pressed onto the test fixture before it can be put back into the aging chamber for subsequent testing. The process is cumbersome and time-consuming, which greatly limits the test throughput, especially when facing the screening of multiple batches and multiple formulations of adhesive strips or a large number of routine quality control tests, resulting in low overall testing efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of existing technologies that can only process a single sample per test, and that the process of changing test pieces is cumbersome and time-consuming, this invention provides an aging test device for waterproof adhesive strips in sportswear.

[0005] The technical solution is as follows: an aging test device for waterproof adhesive strips in sportswear, comprising a mounting frame and two mounting plates connected to the mounting frame; further comprising a motor; a motor fixedly mounted on each mounting plate; a take-up roller fixedly mounted on the rotating shaft of each motor; a pressure plate fixedly mounted on each take-up roller; a sealed cylinder fixedly mounted on each mounting plate; a sealed cylinder rotatably connected to each mounting plate; each sealed cylinder 2 located around the corresponding sealed cylinder 1; a through groove 1 on each sealed cylinder 1; a through groove 2 on each sealed cylinder 2; a squeezing part provided at the upper part of each sealed cylinder 2; a power unit connected to each mounting plate; each sealed cylinder 2 connected to a power unit, the power unit being used to drive the sealed cylinder 2 to rotate.

[0006] Furthermore, several magnetic bases are fixed to the lower part of the mounting bracket for attaching to the metal frame of the testing machine.

[0007] Furthermore, the extrusion section is elastic.

[0008] Furthermore, heat insulation material is installed inside both sealed cylinder one and sealed cylinder two.

[0009] Furthermore, the pressure plate is set to be arc-shaped and matches the curvature of the outer surface of the take-up roller.

[0010] Furthermore, the power unit includes a second motor, a gear, and a gear ring; the second motor is fixedly connected to the rear side of the mounting plate; the output shaft of the second motor is fixedly connected to the gear; the outer surface of the sealed cylinder is fixedly connected to the gear ring; the gear meshes with the gear ring.

[0011] Furthermore, the mounting bracket has a sliding groove, and both mounting plates are connected in a damped sliding connection within the sliding groove.

[0012] Furthermore, it also includes a sealed frame 1; each mounting plate is fixedly connected to a sealed frame 1; each motor 1 is located in a sealed frame 1, and each motor 2 is located in a sealed frame 1, with the sealed frame 1 used to protect motor 1 and motor 2.

[0013] Furthermore, it also includes a second sealed frame; each second sealed cylinder is fixedly connected to a second sealed frame; each second sealed cylinder is rotatably connected to a second sealed frame; each power unit is located inside a second sealed frame, and the second sealed frame is used to protect the power unit.

[0014] Furthermore, the outer ring surface of the sealed cylinder is made smooth.

[0015] The beneficial effects are as follows: 1. This invention can automatically switch the test sections of the waterproof adhesive strip wound on two take-up rollers. After all sections of the waterproof adhesive strip have completed the aging test, the equipment is removed from the aging test machine, and each test section is manually observed to assess whether it exhibits failure phenomena such as cracking, powdering, or detachment from the sportswear fabric. Through the above method, after testing a section of waterproof adhesive strip, there is no need to remove the equipment from the test machine; the test pieces can be automatically and quickly switched, significantly improving testing efficiency.

[0016] 2. After the aging test is completed, the sportswear fabric is rolled around its outer ring surface by the left-side sealed cylinder two. At this time, the waterproof adhesive strip of the sportswear fabric faces the outer ring surface of the sealed cylinder two. During the rolling process, the left-side sealed cylinder two can squeeze the waterproof adhesive strip. Thus, after the aging test is completed, the waterproof adhesive strip can be directly observed by the operator without additional squeezing operation, thereby improving the testing efficiency.

Detailed Implementation

[0023] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example 1: An aging test device for waterproof adhesive strips on sportswear, such as... Figures 1-5 As shown, it includes a mounting bracket 1 and a mounting plate 2; two mounting plates 2 are connected to the mounting bracket 1 in a symmetrical arrangement.

[0025] It also includes a motor 3, a take-up roller 4, a pressure plate 5, a sealed cylinder 21, a sealed cylinder 22, and a power unit; a motor 3 is bolted to the rear side of each mounting plate 2; a take-up roller 4 is fixedly connected to the rotating shaft of each motor 3; a pressure plate 5 is bolted to the upper part of each take-up roller 4; a sealed cylinder 21 is welded to the front side of each mounting plate 2; a sealed cylinder 22 is rotatably connected to the front side of each mounting plate 2; each sealed cylinder 22 is located around the corresponding sealed cylinder 21; a through groove 2101 is opened on the upper part of each sealed cylinder 21; a through groove 2201 is opened on the upper part of each sealed cylinder 22; initially, the through groove 2101 and the through groove 2201 coincide; a pressing part 2202 is provided on the upper part of each sealed cylinder 22; a power unit is connected to each mounting plate 2; each sealed cylinder 22 is connected to a power unit.

[0026] In order to firmly fix the mounting bracket 1 inside the testing machine and thus improve the overall stability of the equipment, several magnetic seats 101 are welded to the lower part of the mounting bracket 1.

[0027] In order to make the extrusion part 2202 press the sportswear fabric 7 tightly onto the sealed cylinder 21, thereby enhancing the sealing effect on the sportswear fabric 7, the extrusion part 2202 is elastic.

[0028] To enhance the sealing effect, heat insulation materials, such as glass wool, are installed inside the sealed cylinder 1 21 and sealed cylinder 2 22.

[0029] To enhance the pressing and fixing effect of the pressure plate 5 on the sportswear fabric 7, the pressure plate 5 is set to be arc-shaped and matches the curvature of the outer surface of the take-up roller 4.

[0030] The power unit includes a second motor 23, a gear 24, and a gear ring 25; the second motor 23 is bolted to the rear side of the mounting plate 2; the output shaft of the second motor 23 is fixedly connected to the gear 24; the outer surface of the sealed cylinder 22 is fixedly connected to the gear ring 25; the gear 24 meshes with the gear ring 25.

[0031] In order to adjust the length of the waterproof strip 8, a sliding groove is opened in the mounting bracket 1, and the two mounting plates 2 are connected in a damped sliding manner in the sliding groove.

[0032] It also includes a sealed frame 6; a sealed frame 6 is welded to the rear side of each mounting plate 2; each motor 3 is located in a sealed frame 6, and each motor 23 is located in a sealed frame 6.

[0033] It also includes a second sealed frame 26; a second sealed frame 26 is welded to the front side of each second sealed cylinder 22; each second sealed cylinder 22 is rotatably connected to a second sealed frame 26; each power unit is located inside a second sealed frame 26.

[0034] by Figure 1 Based on the viewing angle, the side where mounting bracket 1 is located is the rear side.

[0035] In use, multiple waterproof adhesive strips 8 are pressed equidistantly onto the sportswear fabric 7. Then, one end of the sportswear fabric 7 is flattened and placed between the left take-up roller 4 and the pressure plate 5. The bolts are tightened to lower the pressure plate 5 and press it down. Similarly, the other end of the sportswear fabric 7 is fixed between the right take-up roller 4 and the pressure plate 5. Then, using a front-to-back view as a reference, the left motor 3 drives the left take-up roller 4 to rotate counterclockwise. The left take-up roller 4 rolls the sportswear fabric 7 up to its outer surface. Thus, the sportswear fabric 7 between the two take-up rollers 4 is taut, and the section of waterproof adhesive strip 8 to be tested is in the test position. Figure 1As shown; then the entire device is placed inside the aging test machine to perform the aging test on the waterproof adhesive strip 8. After the aging test is completed, the right motor 3 is controlled to drive the right take-up roller 4 to rotate clockwise, and the right take-up roller 4 rolls up the sportswear fabric 7 with the waterproof adhesive strip 8 pressed on its outer surface. At the same time, the left motor 3 is controlled to drive the left take-up roller 4 to rotate clockwise, and the left take-up roller 4 releases the sportswear fabric 7. In this way, the waterproof adhesive strip 8 to be tested is placed again between the two take-up rollers 4, and then the test environment is changed and the test is carried out again. After all the waterproof adhesive strips 8 have undergone the aging test, the device is taken out of the aging test machine, and each waterproof adhesive strip 8 is observed manually to see if there are any defects such as cracking, powdering, or detachment from the sportswear fabric 7. Through the above method, after testing a section of waterproof adhesive strip 8, there is no need to take the device out of the test machine, and the test pieces are automatically and quickly switched, which significantly improves the testing efficiency.

[0036] When conducting an aging test on a section of waterproof adhesive strip 8, both the tested and untested sections of waterproof adhesive strip 8 will be affected by the testing environment, impacting subsequent test results. Therefore, a sealed cylinder 21 is installed around the take-up roller 4. Before conducting the aging test, using a front-to-back view as a reference, the right-side motor 23 drives the corresponding gear 24 to rotate. The gear 24 then drives the gear ring 25 and the sealed cylinder 22 to rotate counterclockwise, causing the right-side extrusion section 2202 to press the sportswear fabric 7 onto the outer ring surface of the right-side sealed cylinder 21. In this way, the right-side sealed cylinder 222 seals the through groove 2101 of the right-side sealed cylinder 21. Simultaneously, the left-side motor 23 drives the gear 24 to rotate, which in turn drives the gear ring 25 and the sealed cylinder 22 to rotate clockwise, causing the left-side sealed cylinder 222 to... The through slot 2101 of the left sealed cylinder 21 is closed; at this time, the take-up roller 4 is completely surrounded by the sealed cylinder 21 and the sealed cylinder 22, thereby preventing the tested and untested waterproof adhesive strips 8 from being affected by the test environment; in addition, the sportswear fabric 7 between the two take-up rollers 4 is placed between the air outlet and the air inlet in the aging test machine. The air outlet is used to blow high temperature and high humidity gas towards the sportswear fabric 7, and the air inlet is used to suck away the gas passing through the sportswear fabric 7 and the waterproof adhesive strips 8, so that the sportswear fabric 7 and the waterproof adhesive strips 8 are always in the test gas environment blown out by the air outlet. The sealed cylinder 21 and the sealed cylinder 22 are located outside the airflow path, and the airflow does not come into contact with the sealed cylinder 21 and the sealed cylinder 22, thereby further preventing the tested and untested waterproof adhesive strips 8 from being affected by the test environment.

[0037] To adjust the length of the waterproof strip 8, a sliding groove is provided inside the mounting frame 1. Both mounting plates 2 are connected in a damped sliding manner within the sliding groove. When testing a longer waterproof strip 8, the two mounting plates 2 are moved away from each other within the sliding groove. Conversely, the two mounting plates 2 are moved closer to each other, and the mounting plates 2 drive the winding rollers 4 on them to move together, thereby adjusting the length of the tension section of the sportswear fabric 7 between the two winding rollers 4, thus changing the length of the waterproof strip 8 tested in a single test to meet different testing requirements.

[0038] This equipment uses a sealed frame 6 to enclose motor 3 and motor 23, and a sealed frame 26 to enclose gear 24 and gear ring 25, to prevent the test environment from damaging motor 3, motor 23, gear 24 and gear ring 25 and reducing their service life.

[0039] Example 2: Based on Example 1, as follows Figures 1-5 As shown, in order to prevent the waterproof adhesive strip 8 on the sportswear fabric 7 from being worn by the second sealed cylinder 22 when it is winding up the sportswear fabric 7, the outer ring surface of the second sealed cylinder 22 is set to a smooth surface.

[0040] After the aging test, before observing each waterproof strip 8, it is usually necessary to manually rub and squeeze the waterproof strip 8 to expose defects for easy observation. To improve testing efficiency, after the aging test, using a front-to-back view as a reference, control the right motor 23 to drive the corresponding gear 24 to rotate. The gear 24 then drives the gear ring 25 and the sealed cylinder 22 to rotate clockwise, opening the through groove 2101 of the right sealed cylinder 21. Then, control the right motor 3 to drive the right take-up roller 4 to rotate counterclockwise. The sportswear fabric 7 is released, and at the same time, the motor 23 on the left drives the corresponding gear 24 to rotate. The gear 24 then drives the gear ring 25 and the sealed cylinder 22 to rotate clockwise. The sealed cylinder 22 on the left winds the sportswear fabric 7 around its outer ring surface. At this time, the waterproof adhesive strip 8 of the sportswear fabric 7 faces the outer ring surface of the sealed cylinder 22. During the winding process, the sealed cylinder 22 on the left can squeeze the waterproof adhesive strip 8. In this way, after the aging test is completed, the waterproof adhesive strip 8 can be directly observed by the operator without additional squeezing operation, thus improving the testing efficiency.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
