[0025] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0026] In this embodiment, see Figure 1-4A mechanical fixture for testing the air tightness of high-barrier packaging bags includes a housing 8, and a fixture mechanism 9 is provided inside the housing 8.

[0027] The clamping mechanism 9 includes a round rod 901, which is fixedly installed on the inner wall of the housing 8. A mounting block 902 is fixedly installed on the surface of the round rod 901. An electric push rod 903 is provided on the outside of the mounting block 902. Two telescopic rods 904 are provided on the outside of the mounting block 902. An adjustment box 905 is provided on the outside of the electric push rod 903. A motor 906 is provided on the top of the adjustment box 905. The output shaft of the motor 906 is fixedly connected to a screw 907 that passes through and extends into the interior of the adjustment box 905 via a coupling. A screw block 908 is threadedly connected to the outside of the screw block 907. A connecting rod 909 is connected to the outside of the screw block 908. A pressure rod 910 is provided on the outside of the connecting rod 909. A pressure plate 911 is provided on the outside of the pressure rod 910 for clamping the high-barrier packaging bag.

[0028] It should be noted that a controller is fixedly installed on the outside of the housing 8. The controller is electrically connected to the electric push rod 903 and the motor 906, which facilitates the control of the electric push rod 903 and the motor 906, so that the clamping mechanism 9 can clamp and fix the high-barrier packaging bag.

[0029] Technical effects: By using the coordinated operation of the electric push rod 903, telescopic rod 904, motor 906, screw 907, screw block 908, connecting rod 909, pressure rod 910, and pressure plate 911, the high-barrier packaging bag can be positioned and clamped, thus preventing it from moving during airtightness testing. This improves the efficiency of airtightness testing for high-barrier packaging bags and allows for clamping and positioning of high-barrier packaging bags of different thicknesses and sizes, expanding the application range of the mechanical fixture for airtightness testing of high-barrier packaging bags.

[0030] Optionally, see Figure 1 It also includes a support leg 1, a base plate 2 on the outside of the support leg 1, a support rod 3 on the outside of the base plate 2, a fixing plate 4 fixedly installed on the outside of the support rod 3, a cylinder 5 on the outside of the fixing plate 4, a top cover 6 fixedly connected to the end of the cylinder 5 away from the fixing plate 4, an airtightness detection hole 7 on the outside of the top cover 6, and a box body 8 fixedly installed on the top of the base plate 2.

[0031] It should be added that as the top cover 6 moves downward, it can close the opening at the top of the box 8, thereby improving the sealing during the airtightness test and preventing any impact on the airtightness test, thus improving the accuracy of the airtightness test of the high-barrier packaging bag.

[0032] Technical effect: By using the cylinder 5, top cover 6 and air tightness detection hole 7 in combination, the purpose of air tightness detection of high barrier packaging bags is achieved, so that the high barrier packaging bags are not affected by the outside air during the air tightness detection process, thereby improving the accuracy of air tightness detection.

[0033] Optionally, two cylinders 5 are provided, and the two cylinders 5 are symmetrically distributed about the airtightness detection hole 7. The purpose is to drive the top cover 6 to move up and down at the same time, so that the top cover 6 is more stable during the movement.

[0034] Optionally, the screw block 908 is provided with a limiting rod on its outside, and the inner wall of the adjusting box 905 is provided with a limiting groove, and the surface of the limiting rod is slidably connected to the inner wall of the limiting groove.

[0035] Technical effect: The limiting rod and the limiting groove work together to limit the screw block 908, so that the screw block 908 can move up and down under the drive of the screw 907, which facilitates the clamping of the high-barrier packaging bag.

[0036] Optionally, the size of the top cover 6 is adapted to the size of the box body 8, and the top cover 6 and the box body 8 are located in the same vertical direction, so as to achieve the purpose of sealing the top of the box body 8, thereby enabling the high barrier packaging bag to be tested for air tightness in the box body 8.

[0037] Optionally, the inner wall of the regulating box 905 is provided with a through-hole at both ends. The inner wall of the through-hole is slidably connected to the surface of the connecting rod 909. The purpose is to allow the connecting rod 909 to move up and down in the through-hole, and at the same time to limit the movement of the connecting rod 909, so as to prevent the connecting rod 909 from shaking during the movement and improve the stability of the movement of the connecting rod 909.

[0038] Optionally, a rubber pad is fixedly installed at the bottom of the pressure plate 911. The size of the rubber pad is the same as that of the pressure plate 911. Its function is to protect the surface of the high-barrier packaging bag, thereby preventing damage to the surface of the high-barrier packaging bag due to excessive pressure.

[0039] Optionally, a sealing ring is provided on the side of the top cover 6 near the box body 8. The diameter of the sealing ring is the same as the diameter of the box body 8, which achieves the purpose of better sealing of the box body 8, so that the box body 8 will not leak air during the air tightness test of the high barrier packaging bag, thus improving the sealing performance of the box body 8.

[0040] Optionally, there are two clamping mechanisms 9, which are arranged symmetrically about the center of the box 8. They can clamp the high-barrier packaging bag from the left and right sides, thereby making the high-barrier packaging bag clamped more stably.

[0041] Optionally, the regulating box 905 is provided with a fixing frame on the outside, and the motor 906 is connected to the regulating box 905 through the fixing frame. The purpose is to limit and fix the motor 906, so that the motor 906 is more stable during use and avoids the impact of shaking on the clamping of the high barrier packaging bag.

[0042] Working principle: When the airtightness of a high-barrier packaging bag needs to be tested, it needs to be clamped. First, the high-barrier packaging bag needs to be placed into the housing 8. Then, the electric push rod 903 is activated, which moves the adjusting box 905. When the adjusting box 905 moves to the side above the high-barrier packaging bag, the electric push rod 903 is turned off. Then, the motor 906 is activated, which drives the screw 907 to rotate. The screw 907 drives the screw block 908 to move downward, which in turn drives the connecting rod 909 to move downward. At the same time, the connecting rod 909 also drives the pressure rod 910 to move downward. Then, the pressure rod 910 drives the pressure plate 911 to move downward, so that the pressure plate 911 can clamp and fix the high-barrier packaging bag. At the same time, the clamping mechanism 9 on the other side performs the same operation, thus clamping the high-barrier packaging bag from both sides, making the clamping more stable.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
