[0023] refer to Figure 1 、 Figure 4 During the clamping operation, the intermediate film product surrounds the test roller 103 and places both ends between the fixed clamping plate 201 and the movable clamping plate 205. Then, the clamping cylinder 203 drives the movable clamping plate 205 close to the fixed clamping plate 201 under the action of the external air source to clamp the two ends of the intermediate film product. The clamping area is larger and the clamping is more stable. Therefore, the test is more comprehensive. During the test, the test cylinder 106 drives the sliding seat 104 to move on the slide rail 102 under the action of the preset air pressure, so that the sliding seat 104 is away from the clamping assembly 2, so that the intermediate film product is stretched, and the indicator needle 105 refers to the scale line 101 to judge whether the intermediate film product is qualified, and the ultimate pressure that it can withstand can also be judged, and the test is reliable.

[0024] A slide rail 102 and a test cylinder 106 are fixedly installed on the right side of the base plate 1. There are two slide rails 102, which are axially symmetrical. A sliding seat 104 is slidably installed on the slide rail 102. The output end of the test cylinder 106 is fixedly connected to the sliding seat 104. A test roller 103 is installed on the upper part of the sliding seat 104. The test roller 103 is horizontally arranged. An indicator needle 105 is fixedly connected to the rear part of the sliding seat 104. A scale line 101 is provided on the base plate 1 at the position of the indicator needle 105.

[0025] During the clamping operation, the intermediate film product surrounds the test roller 103 and places its two ends between the fixed clamping plate 201 and the movable clamping plate 205. Then, under the action of the external air source, the clamping cylinder 203 drives the movable clamping plate 205 to approach the fixed clamping plate 201 to clamp the two ends of the intermediate film product. The clamping area is larger and the clamping is more stable. Therefore, the test is more comprehensive. During the test, the test cylinder 106 drives the sliding seat 104 to move on the slide rail 102 under the action of the preset air pressure, so that the sliding seat 104 is away from the clamping component 2, so that the intermediate film product is stretched, and the indicator needle 105 refers to the scale line 101 to judge whether the intermediate film product is qualified, and the ultimate pressure that it can withstand can also be judged. The test is reliable, and the intermediate film does not need to be fully unfolded during the test. The overall space occupied is small. The setting of the clamping component 2, sliding seat 104, slide rail 102, test roller 103, and test cylinder 106 can increase the area of ​​the intermediate film clamping, and the test does not need to be fully unfolded. The space occupied is small, and the test is convenient.

[0026] Working principle: During the clamping operation, the intermediate film product surrounds the test roller 103, and the two ends are placed between the fixed clamping plate 201 and the movable clamping plate 205. Then, the clamping cylinder 203, under the action of the external air source, drives the movable clamping plate 205 to approach the fixed clamping plate 201 to clamp the two ends of the intermediate film product. The clamping area is larger and the clamping is more stable. Therefore, the test is more comprehensive. During the test, the test cylinder 106, under the action of the preset air pressure, drives the sliding seat 104 to move on the slide rail 102, so that the sliding seat 104 is away from the clamping component 2, so that the intermediate film product is stretched, and the indicator needle 105 refers to the scale line 101 to judge whether the intermediate film product is qualified, and the ultimate pressure that can be withstood can also be judged. The test is reliable, and the intermediate film does not need to be fully unfolded during the test, and the overall space occupied is small.
