[0047] Embodiment 2

[0048] In order to further improve the detection efficiency of the whole detection device, the application also provides another embodiment, which is different from the above-mentioned embodiment in that the detection plate 4 is an octagonal plate structure, and the number of swing shafts 18 is 8. Through the arrangement of the above-mentioned structure, the above-mentioned device can detect the pulling degree of at least 8 plastic bags at a time during the detection process, which meets the detection needs of a large number of plastic bags.

[0049] In summary, during work, one end of the handle of the plastic bag is connected to the end position of the swing shaft 18 through the handle clamping mechanism, and the bottom edge position of the plastic bag is connected to the detection plate 4 through the bottom edge mechanism. During the detection process, on the one hand, we can start the pulling motor 8 and the rotating motor 6 separately, at this time, under the cooperation of the pulling mechanism, the handle part of the plastic bag can be rotated and shaken to simulate the actual carrying of the object, and under the action of the rotating mechanism, the bottom loading part of the plastic bag can be linearly pulled in multiple directions; on the other hand, the above-mentioned motors can be started at the same time, so that the whole part of the plastic bag is linearly pulled in multiple dimensions and multiple angles under the simultaneous action of the above-mentioned pulling mechanism and rotating mechanism, and the pulling degree of the plastic bag is more accurately detected.
