A guide rod 201 is fixedly connected to the bottom of the mounting plate 7. A hydraulic telescopic rod 203 is hinged to the bottom of the mounting plate 7 via a first fixed seat 202. A second fixed seat 204 is hinged to the bottom of the hydraulic telescopic rod 203. A guide rod 205 is fixedly connected to the bottom of the second fixed seat 204 via a tension gauge 205. A connecting plate 209 is provided at the bottom of the guide plate 206. A fixing clip 212 is fixedly connected to the top of the connecting plate 209 and the bottom of the guide plate 206 respectively. A telescopic cylinder 210 is installed on the side of the fixing clip 212. The telescopic part of the telescopic cylinder 210 passes through the fixing clip 212 and is slidably connected to the fixing clip 212. A limit plate 211 is fixedly connected to the end of the telescopic part of the telescopic cylinder 210. An igniter 5 is fixedly connected to the side of the mounting bracket 1 through a telescopic rod. The igniter 5 is located between the guide plate 206 and the connecting plate 209.

[0029] The hydraulic telescopic rod 203 and the telescopic cylinder 210 work together. The hydraulic telescopic rod 203 pushes the moving plate 207 to move along the guide rod 201, while the telescopic cylinder 210 drives the limiting plate 211 to fix the sample in the fixing clamp 212, ensuring that the sample is subjected to uniform force during the test.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the auxiliary component 3 includes an auxiliary rod 301 fixedly connected to the bottom of the mounting plate 7. The auxiliary rod 301 is located on the side of the guide rod 201. A movable plate 207 is slidably connected to the outer surface of the auxiliary rod 301. The side of the movable plate 207 is fixedly connected to the guide plate 206. A fixed plate 208 is fixedly connected to the outer surface of the auxiliary rod 301. The side of the fixed plate 208 is fixedly connected to the connecting plate 209. A positioning block 302 is fixedly connected to the side of the auxiliary rod 301. A protective plate 303 is fixedly connected to the side of the positioning block 302. An extension plate 304 is hinged to the end of 03. The protective plate 303 is located on the side of the hydraulic telescopic rod 203. The positioning block 302 is located on the top of the moving plate 207. The guide plate 206 is located directly above the connecting plate 209. The guide plate 206 and the connecting plate 209 are the same size. Two auxiliary rods 301 are provided. The two auxiliary rods 301 are located on both sides of the guide rod 201. A controller 6 is fixedly connected to the side of the mounting frame 1.

[0031] A protective plate 303 is hinged to the side of the positioning plate 302, and an extension plate 304 is hinged to the end of the protective plate. The protective plate 303 is located on the side of the hydraulic telescopic rod 203, which facilitates the protection of the hydraulic telescopic rod 203 during operation.

[0032] The working process of this utility model is as follows: When using the peel test sample preparation equipment designed in this scheme, first check whether the device is working properly, ensuring that all components are installed firmly and functioning normally. Install the sample to be tested onto the test assembly 2, start the igniter 5 to bake the surface of the sample to facilitate subsequent testing, start the controller 6 to control the hydraulic telescopic rod 203 and the telescopic cylinder 210 to work together. The hydraulic telescopic rod 203 pushes the moving plate 207 to move along the guide rod 201, while the telescopic cylinder 210 drives the limiting plate 211 to fix the sample in the fixing clamp 212, ensuring that the sample is subjected to uniform force during the test. As the moving plate 207 moves gradually, the sample is gradually peeled off under the monitoring of the tensile tester 205. The tensile tester 205 records and feeds back the tensile data during the peeling process in real time. During the test, the auxiliary rod 301 and the positioning block 302 in the auxiliary assembly 3 play a role in stabilizing the position of the sample, while the protective plate 303 and the extension plate 304 effectively protect the hydraulic telescopic rod 203. After the test is completed.
