Description

Technical Field

[0001] This utility model relates to the field of adhesive aging testing, and in particular to an adhesive aging testing device. Background Technology

[0002] Adhesive aging tests are experiments used to evaluate changes in the performance of adhesives under long-term use and environmental influences. These tests are commonly used in quality control and materials science research to ensure the reliability and durability of adhesives in practical applications.

[0003] In adhesive aging tests, adhesive samples are usually placed directly in a high-temperature aging test chamber and heated at high temperatures to observe the changes in the adhesive after high temperature. However, simply heating the adhesive sample at high temperature results in limited experimental data and cannot be used to conduct thermal cycling tests on the adhesive sample according to real-world conditions, thus having certain shortcomings.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figure 1-3 The above describes an adhesive aging test apparatus.

[0035] Example 1

[0036] The test chamber includes a test chamber 1, a hot air blower 2, a clamp 4, a drive assembly 3, and a locking assembly 5. The bottom of the test chamber 1 contains cold water for cooling the adhesive sample. When the temperature of the cold water inside the test chamber 1 rises, ice can be added to keep the water temperature below room temperature. The hot air blower 2 is mounted on the test chamber 1 and is used to heat the adhesive sample. The clamp 4 is located inside the test chamber 1 and is used to clamp and restrain the adhesive sample. The drive assembly 3 is mounted on the test chamber 1 and is used to drive the clamp 4 to rotate inside the test chamber 1. This allows the clamp 4 to move the solidified adhesive sample to the heating zone on one side of the hot air blower 2 or to place the solidified adhesive sample in the cold water, thus conducting a hot and cold cycle test on the solidified adhesive sample. The locking assembly 5 is located outside the test chamber 1 and is used to lock the drive assembly 3.

[0037] In particular, the drive assembly 3 includes a connecting shaft 31, a mounting plate 32, and a connecting plate 33. The outer wall of the connecting shaft 31 is rotatably connected to the test chamber 1, and the liquid level of the cold water inside the test chamber 1 is located at the bottom of the connecting shaft 31. The bottom of the mounting plate 32 is fixedly connected to the connecting shaft 31. A clamp 4 is installed on one side of the mounting plate 32. The clamp 4 consists of two clamping plates and a screw. One clamping plate is fixed to one side of the mounting plate 32, and the other clamping plate is slidably disposed on one side of the mounting plate 32 via the screw. Thus, when the screw rotates, the two clamping plates can move relative to each other or in opposite directions, thereby enabling the drive assembly 33 to rotate. The clamping of the adhesive sample is existing technology and will not be described in detail here. The bottom of the connecting plate 33 is fixedly connected to the connecting shaft 31. The connecting plate 33 is snapped onto the outside of the test chamber 1 by the locking component 5. The connecting plate 33 and the mounting plate 32 are located on the same side of the connecting shaft 31. Thus, the connecting plate 33 drives the connecting shaft 31 to rotate, which in turn drives the mounting plate 32 and the clamp 4 to rotate, thereby changing the position of the clamp 4. The clamp 4 is located in cold water. Under the weight of the mounting plate 32 and the connecting plate 33, the clamp 4 can ensure that the adhesive sample is stably located in the cold water.

[0038] Example 2

[0039] Based on embodiment 1, the locking assembly 5 includes a mounting base 51 and a locking rod 52. The mounting base 51 is fixedly installed on one side of the test chamber 1. The outer wall of the locking rod 52 is slidably inserted into the mounting base 51. A locking hole corresponding to the locking rod 52 is opened on one side of the mounting base 51, so that the locking rod 52 is engaged with the locking hole, which allows the connecting plate 33 and the mounting plate 32 to be in a vertically upward state, thereby enabling the mounting plate 32 to drive the clamp 4 to stably correspond to the hot air blower 2.

[0040] Furthermore, the locking assembly 5 also includes a fixed sleeve 53, a handle 54, a fixed collar 55, and a limiting spring 56. The fixed sleeve 53 is fixedly connected to one side of the connecting plate 33. One end of the outer wall of the locking rod 52 is slidably inserted into the fixed sleeve 53. The handle 54 is fixedly connected to one end of the locking rod 52. The fixed collar 55 is fixedly sleeved on the outside of the locking rod 52 and slidably sleeved on the inside of the fixed sleeve 53. The limiting spring 56 is slidably sleeved on the outside of the locking rod 52. The limiting spring 56 is located on the side of the fixed collar 55 away from the mounting base 51. The limiting spring 56 can provide an elastic compressive force to the locking rod 52 through the fixed collar 55, thereby ensuring the stability of the locking rod 52 and the mounting base 51.

[0041] Furthermore, it also includes a pressure-sensitive switch 7 and a main power switch 6. The pressure-sensitive switch 7 is installed inside the mounting base 51, and the end of the locking rod 52 is pressed against the pressure-sensitive switch 7. The main power switch 6 is installed on one side of the test chamber 1. The hot air blower 2 is electrically connected to an external power source through the main power switch 6 and the pressure-sensitive switch 7. That is, when the locking rod 52 is engaged with the mounting base 51, the clamp 4 moves the glue sample to correspond with the hot air blower 2, and under the action of the limit spring 56, the locking rod 52 presses the pressure-sensitive switch 7, and the hot air blower 2 is powered on and works. When the clamp 4 moves the glue sample to the cold water, the locking rod 52 no longer presses the pressure-sensitive switch 7, and the hot air blower 2 is powered off and stops working.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
