Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to an airtight zipper detection device. Background Art

[0002] An airtight zipper is a specially designed zipper whose core function is to prevent gas, moisture, and other impurities from penetrating through the tiny gaps in the zipper, ensuring that the environment on both sides of the zipper remains effectively isolated and pure. During the production process of airtight zippers, it is crucial to ensure that their airtightness meets the specified standards. Therefore, after manufacturing, the airtight zippers will be rigorously tested using professional airtightness testing equipment. These testing equipment simulates the pressure changes in the actual use environment to test the sealing effect of the zipper in the closed state.

[0003] The testing equipment currently on the market generally has the problem of low detection accuracy when performing air-tightness tests on air-tight zippers. It is difficult to display the test results intuitively and accurately, which makes it difficult for operators to quickly determine whether the air-tightness performance of the zipper meets the standards. In addition, the degree of automation of these devices is relatively low, and they rely heavily on manual operation, which not only increases labor intensity, but also seriously restricts the improvement of detection efficiency.

[0027] See also Figure 1 - Figure 5 As shown, an airtight zipper detection device includes:

[0028] Support frame 1;

[0029] The top of the support frame 1 is fixedly connected to an air chamber 3, the middle of the air chamber 3 is fixedly connected to a base structure 4, four support rods 5 are fixedly connected to the air chamber 3 at equal distances, the outer surfaces of the support rods 5 are commonly mounted with a mounting plate 6, the top of the mounting plate 6 is fixedly connected to a hydraulic cylinder 7, the output end of the hydraulic cylinder 7 passes through the middle of the bottom end of the mounting plate 6 and is fixedly connected to a connecting seat 14, the bottom end of the connecting seat 14 is fixedly connected to a detection mechanism 8, and by setting the hydraulic cylinder 7, the height of the detection mechanism 8 can be adjusted;

[0030] The detection mechanism 8 includes a connecting frame 81, the bottom end of the connecting frame 81 is fixedly connected to a bottom plate 82, the bottom end of the bottom plate 82 is fixedly connected to a rubber ring 85, and the connecting frame 81 is fixedly connected to the connecting seat 14;

[0031] The base structure 4 includes a base 41, a backing plate 42 is fixedly inserted and connected to the middle of the top of the base 41, a connecting groove 43 is opened in the middle of the top of the backing plate 42, and a connecting pipe 44 is fixedly inserted and connected to one end of the base 41. The base 41 is fixedly connected to the air chamber 3;

[0032] Both sides of the top of the base structure 4 are fixedly connected to the limit rod 13, the top side of the mounting plate 6 is fixedly connected to the controller 12, the outer surface of the hydraulic cylinder 7 is installed with a pressure gauge 9, by setting the pressure gauge 9, the air pressure can be visually observed, one end of the pressure gauge 9 is fixedly connected to the air pipe 10, the end of the air pipe 10 away from the pressure gauge 9 is fixedly connected to the air chamber 3, one end of the detection mechanism 8 is installed with a water pipe 11, a hydraulic device 2 is installed in the support frame 1, and one end of the hydraulic cylinder 7 is fixed to the hydraulic device 2;

[0033] One end of the barometer 9 is connected to the air pump.

[0034] Depend on Figure 4 It can be seen that a groove 83 is formed at the top of the bottom plate 82 , a through groove 84 is formed at the bottom end of the lower groove wall of the groove 83 , a rubber ring 85 is arranged around the through groove 84 , and the connecting frame 81 and the water pipe 11 are installed together.

[0035] As can be seen from the above, the output end of the hydraulic cylinder 7 extends downward and pushes the connecting seat 14 to move downward, the connecting seat 14 pushes the connecting frame 81 to move downward, and the connecting frame 81 drives the bottom plate 82 to move downward, so that the rubber ring 85 is in close contact with the zipper, effectively compacting the zipper, and the end of the water pipe 11 away from the connecting frame 81 is connected to the water tank through the connecting pump. After the zipper is compacted, the water in the water tank is introduced into the groove 83 through the connecting pump, and the air pump is started, so that the air pipe 10 transmits the gas to the air chamber 3. After adjusting the air pressure, the air tightness of the zipper is judged by observing whether bubbles appear on the water surface in the through groove 84.

[0036] Example 2:

[0037] refer to Figure 5 As shown, the limiting rods 13 are fixedly connected to the top of the base 41 , and the outer surface of one end of the limiting rods 13 is in close contact with one end of the connecting frame 81 .

[0038] As can be seen from the above, during the testing process, the zipper is placed on the top of the base 41 and directly above the connecting groove 43. The zipper is compacted using the testing mechanism 8, and then the air tightness of the zipper is tested using the air chamber 3, the pressure gauge 9, the air pipe 10 and the connecting groove 43. The connecting frame 81 can be limited by the limiting rod 13.

The switch is activated by the controller 12 to activate the hydraulic cylinder 7. The output end of the hydraulic cylinder 7 extends downward and pushes the connecting seat 14 fixedly connected thereto to move downward. The connecting seat 14 pushes the connecting frame 81 fixedly connected thereto to move downward. The connecting frame 81 drives the bottom plate 82 fixedly connected thereto to move downward, so that the rubber ring 85 is in close contact with the zipper. The rubber ring 85 is inlaid with a high elastic material to ensure comprehensive contact and sealing with the zipper, effectively compacting the zipper. During the lifting process of the connecting frame 81, one end of the connecting frame 81 is always in close contact with the outer surface of the two limit rods 13, which improves the connection. The stability of the lifting and lowering of the connecting frame 81 effectively avoids any possible shaking or deviation. The end of the water pipe 11 away from the connecting frame 81 is connected to the water tank through a connecting pump. After the zipper is compacted, the water in the water tank is introduced into the groove 83 through the connecting pump, and the air pump is started. The air is pumped by the air pump so that the air pipe 10 transmits the gas to the air chamber 3. After adjusting the air pressure, the air tightness of the zipper is judged by observing whether bubbles appear on the water surface in the groove 84. If the water surface is clear and there are no bubbles, it proves that the zipper has good airtightness. For long zippers, a spring ruler is cleverly integrated into the design to seal the undetected part. After the current section is detected, continue to pull forward to achieve continuous detection of the remaining parts, which greatly improves the detection efficiency and convenience.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
