For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] Referring to Figures 1-3 According to the embodiment of the utility model packaging bag load test machine, including base 11, the base 11 is connected with the bearing plate 12 through the upward extension of a support frame, the bearing plate 12 is connected with the upper cover 13 through the upward extension of the second support frame, the bearing plate 12 is equipped with the through slot 14 that passes through up and down, the upper side of the upper cover 13 is equipped with a cylinder 21, the piston rod in the cylinder 21 downwardly penetrates the through slot 14, and the lower end of the piston rod is connected with the pressing plate 15 through the pressure sensor.

[0028] In addition, the bearing plate 12 on the left and right sides of the through slot 14 is respectively equipped with a hanging plate 16, the upper cover 13 is further provided with two left and right distributed second cylinders 17, the lower end of the second piston rod in the second cylinder 17 is equipped with a top plate 18, and the left and right two top plates 18 are respectively on the upper side of the left and right hanging plates 16.

[0029] When the packaging bag needs to be tested, the staff can first put the packaging bag on the pressing plate 15, then make the packaging bag pass through the through slot 14 to extend to the upper side of the bearing plate 12, then the staff puts the two handles of the packaging bag on the left and right hanging plates 16 respectively, and then makes the top plate 18 descend to press on the hanging plate 16, so as to avoid the handle from slipping off the hanging plate 16. At this time, the fixing of the packaging bag is completed, and then the No. 1 air cylinder 21 can control the pressing plate 15 to sink to test the packaging bag. The pressure sensed by the pressure sensor is the pressure borne by the packaging bag. This test method is the prior art and will not be described again. The above is the first fixing method of the packaging bag.

[0030] In the second embodiment of the packaging bag load test machine, in order to adapt the packaging bag load test machine to packaging bags without handles, the specific installation mode of the hanging plate 16 is that the bearing plate 12 on the left and right sides of the through slot 14 is respectively provided with a spring slot, and the hanging plate 16 is slidingly connected to the spring slot and connected to the bottom surface of the spring slot through a spring.

[0031] Through this setting, if the packaging bag is not provided with a handle, in the second fixing method of the packaging bag, the top plate 18 can be pressed downward until it abuts against the upper side of the bearing plate 12 after the position of the packaging bag is corrected, so that the opening edge of the packaging bag is pressed between the bearing plate 12 and the top plate 18. At this time, the hanging plate 16 is pressed in the spring slot, so that the packaging bag is fixed for testing.
