[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Through the arrangement of the plurality of locking universal wheels 9 on the bottom of the support base 1, it is convenient for the operator to move and fix the device. The support base 1 is fixedly installed with a mounting frame 2 and a glass A glass water tank 5, a hydraulic telescopic rod 6 is fixedly installed on the inner bottom of the glass water tank 5, a placement frame 10 is fixedly installed on the telescopic end of the hydraulic telescopic rod 6, two slide grooves 14 are provided on the inner bottom of the placement frame 10, and a tightening mechanism is provided in both slide grooves 14, the tightening mechanism includes a sliding block 15 slidably connected in the slide groove 14, a clamping plate 11 is fixedly installed on the top of the sliding block 15, a rubber pad 13 is fixedly installed on the side wall of the clamping plate 11, and a spring 16 is fixedly connected between the side wall of the sliding block 15 and the inner side wall of the slide groove 14;

[0024] The support seat 1 is provided with two squeezing mechanisms, both of which extend into the glass water tank 5. The squeezing mechanisms include a connecting member 7 slidably connected to the support seat 1, and an end of the connecting member 7 extends into the glass water tank 5 and is fixedly mounted with a push plate 8;

[0025] A driving mechanism is provided on the top of the mounting frame 2, which passes through the two extrusion mechanisms and is threadedly connected thereto. The driving mechanism includes a servo motor 3 fixedly mounted on the top of the mounting frame 2, a double-headed screw 12 is fixedly mounted on the end of the output shaft of the servo motor 3, and the double-headed screw 12 passes through the two connecting pieces 7 and is threadedly connected thereto. Through the arrangement of the hydraulic telescopic rod 6, the placement frame 10, the tightening mechanism, the driving mechanism and the extrusion mechanism, when performing a sealing test on the PE bag, it can ensure that the operator can quickly and accurately determine whether the PE bag is leaking.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] When it is necessary to test the sealing of the PE ziplock bag, first, the operator injects a proper amount of water into the glass water tank 5meow to make the PE ziplock bag in an expanded state, and then presses the self-sealing strip on the PE ziplock bag to make the inside of the PE ziplock bag sealed. At this time, the PE ziplock bag is in an expanded state, and then the two clamps 11 are pulled away from each other, and the PE ziplock bag is placed between the two clamps 11. The clamps 11 are loosened, and the sliding block 15 drives the clamps 11 to slide under the tension of the spring 16. The rubber pads 13 on the two clamps 11 hold the expanded PE ziplock bag tightly and fix it, and the hydraulic telescopic rod 6 is started to contract. The hydraulic telescopic rod 6 drives the PE ziplock bag between the two clamping plates 11 to be completely immersed in the water in the glass water tank 5. After standing for a period of time to allow the bubbles in the water to be completely discharged, the servo motor 3 is started to rotate, and the servo motor 3 drives the push plates 8 on the two connecting parts 7 to gradually approach each other. The two push plates 8 squeeze the side walls of the corresponding clamping plates 11 respectively, and the rubber pads 13 on the two clamping plates 11 gradually squeeze the side walls of the PE ziplock bag. At this time, the operator observes whether there are bubbles on the PE ziplock bag through the glass water tank 5. If bubbles are generated, it means that the sealing of the PE ziplock bag is unqualified. If no bubbles are generated, it means that the sealing of the PE ziplock bag is qualified.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
