Description

Technical Field

[0001] This utility model relates to the field of coating film technology, specifically to a device for testing the crack resistance performance of a burn-resistant, dry-resistant, non-stick film. Background Technology

[0002] Heat-resistant and non-stick coatings are widely used in cookware, industrial heating equipment and other fields. Their surface crack resistance directly affects the product's service life and safety.

[0003] The impact resistance of a film is often affected by factors such as temperature, humidity, and impact velocity. The impact resistance test of a film measures the impact strength of the coating film, which is a property for evaluating the rapid deformation of the coating under high-rate load impact. This stress change is closely related to its elongation, adhesion, and static hardness. In existing testing methods, a weighted ball is dropped freely onto a sample to impact it, and the film is then tested for cracks, wrinkles, and peeling. The height at which the sample is dropped is the impact strength of that sample. The higher the height the film is dropped, the better its impact resistance and crack resistance.

[0004] However, existing equipment cannot continuously impact the sample with weighted spheres of different masses during testing, resulting in low testing efficiency. Utility Model Content

[0013] Figure 2 This is a front view of the present invention. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] See attached diagram. Figures 1 to 2 The fire-resistant, dry-resistant, non-stick film crack resistance testing device in this embodiment includes a base 1, a frame 2 on the base 1, a mounting plate 20 and a feeding plate 21 on the top of the frame 2, a drive mechanism on the mounting plate 20, a feeding mechanism on the feeding plate 21, an output end of the drive mechanism connected to the feeding mechanism, a hydraulic cylinder 10 on the base 1, and a test platform 3 at the output end of the hydraulic cylinder 10.

[0016] Furthermore, the drive mechanism includes a drive motor 4, the output end of the drive motor 4 is provided with a cam 40, the cam 40 is provided with a cam groove 41, and a cylindrical pin 42 is slidably installed in the cam groove 41.

[0017] Furthermore, the feeding mechanism includes a vertical groove 5, a first horizontal groove 50, and a second horizontal groove 51 disposed on the feeding plate 21; a vertical plate 6 is disposed between the first horizontal groove 50 and the second horizontal groove 51, and a horizontal plate 7 is disposed on one side of the vertical plate 6, with one end of the horizontal plate 7 hinged to a cylindrical pin 42; a first stop block 60 and a second stop block 61 are respectively disposed on the front end face of the top and bottom of the vertical plate 6; the width of the first stop block 60 and the second stop block 61 is adapted to the width of the vertical groove 5.

[0018] Furthermore, a slide rail 62 is provided on one side of the horizontal plate 7, and the horizontal plate 7 is slidably connected to the slide rail 62.

[0019] Furthermore, one end of both the first stop 60 and the second stop 61 is integrally formed with a bevel 8.

[0020] In one possible implementation, the test bench 3 is equipped with a clamping and limiting device to fix and limit the sample.

[0021] It should be noted that, in order to facilitate the demonstration of the structure of the feeding mechanism in this embodiment, the attached figure shows an internal schematic diagram of the feeding plate 21.

[0022] Working principle: The sample to be tested is placed on the test platform 3 and fixed firmly; then the height of the test platform 3 is adjusted by the hydraulic cylinder 10; according to the test requirements, different weighted balls 9 are alternately placed in the vertical groove 5 of the feeding plate 21. The weighted balls 9 are blocked by the first stop 60 in the first horizontal groove 50. During the test, the drive motor 4 is started, and the drive motor 4 drives the cam 40 to rotate. At this time, under the coordinated action of the cam groove 41, the slide rail 62 and the cylindrical pin 42, the horizontal plate 7 can move back and forth. When the horizontal plate 7 moves forward, the first stop 50 and the second stop 51 move to the left, so that the weighted balls 9 slide down the inclined surface 8 on the first stop 50 and fall to the first stop 50. On the second stop 51, the second stop 51 simultaneously blocks the weighted ball 9. As the cam 40 rotates, the horizontal plate 7 moves to the right, causing the first stop 50 and the second stop 51 to move to the right. At this time, the second stop 51 is connected to the vertical groove 5, and the weighted ball 9 falls along the vertical groove 5 onto the template for impact testing. Meanwhile, the first stop 50 blocks the vertical groove 5 again, thus blocking the next weighted ball 9 on the first stop 50. In this way, as the cam 40 rotates, it drives the horizontal plate 7 to move left and right in a cycle, so that the first stop 50 and the second stop 51 control the conduction of the vertical groove 5. Thus, the weighted ball 9 can be continuously dropped as needed to improve testing efficiency.

[0023] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
