It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0026] like Figure 1-4 As shown, the present invention proposes a plastic bag ductility testing machine, comprising a testing platform 1, a mounting frame 2, and a testing installation slot 3. The mounting frame 2 is welded above the testing platform 1, and the testing installation slot 3 is provided on the upper surface of the testing platform 1. A hydraulic rod 4 is installed on the upper surface of the mounting frame 2, and the piston rod of the hydraulic rod 4 passes through the top cavity wall of the mounting frame 2. The end of the piston rod of the hydraulic rod 4 is connected to a connecting bracket 5, and a pressure frame 6 is welded to the bottom of the connecting bracket 5.

[0027] An air pump 9 is installed on the lower surface of the detection platform 1, and the exhaust end of the air pump 9 is conductively connected to the detection installation groove 3;

[0028] The surface of the detection platform 1 is welded with guide columns 11, which are symmetrically arranged. A lifting sleeve 12 is slidably provided on the surface of the guide column 11, and a height detection cross bar 13 is connected between two groups of the lifting sleeves 12.

[0029] It should be noted that the plastic bag is laid flat in the detection installation groove 3, and the hydraulic rod 4 is controlled to extend by the switch 10. The piston rod end of the hydraulic rod 4 pushes the pressure frame 6 down through the connecting bracket 5. The pressure frame 6 is pressed on the surface of the plastic bag. The air pump 9 can inject air into the plastic bag. The plastic bag expands under the action of the gas and lifts the height detection cross bar 13 until the plastic bag breaks. The expansion size of the plastic bag can be measured by matching the scale 16 with the lifting sleeve 12, so that the ductility of the plastic bag can be tested by Kuas.

[0030] In this embodiment, if Figure 3 and Figure 4As shown, a rubber pad 8 is pasted on the bottom of the inner cavity of the detection installation groove 3, and a corresponding hole is opened on the surface of the rubber pad 8 corresponding to the exhaust end position of the air pump 9. A rubber frame 7 is pasted on the lower surface of the pressure frame 6. After the pressure frame 6 is lowered, the rubber frame 7 abuts against the rubber pad 8.

[0031] It should be noted that, after the pressing frame 6 is lowered, the rubber frame 7 and the rubber pad 8 abut against each other, which can improve the sealing performance at the edge of the plastic bag.

[0032] In this embodiment, if Figure 1 As shown, a switch 10 is installed on the outer wall surface of the detection platform 1, and the switch 10 is electrically connected to the air pump 9 and the hydraulic rod 4 through a wire.

[0033] It should be noted that the air pump 9 and the hydraulic rod 4 can be controlled separately by the switch 10 .

[0034] In this embodiment, if Figure 3 As shown, threaded holes are formed through the surface of the lifting sleeve 12 , and locking screws 15 are threadedly connected to the inner cavities of the threaded holes.

[0035] It should be noted that the lifting sleeve 12 can be locked by locking the screw rod 15 .

[0036] In this embodiment, if Figure 3 As shown, an expansion plate 14 is welded to the middle of the height detection cross bar 13, and the lower surface of the expansion plate 14 is flush with the lower surface of the lifting sleeve 12. A scale 16 is opened on the surface of the guide column 11, and the height detection cross bar 13 is located between the connecting bracket 5 and the pressure frame 6.

[0037] It should be noted that the contact area between the height detection cross bar 13 and the plastic bag can be increased by the expansion plate 14, so that the plastic bag can quickly lift the height detection cross bar 13 after expansion. The lower surface of the expansion plate 14 is flush with the lower surface of the lifting sleeve 12, and the height of the height detection cross bar 13 can be conveniently measured by the scale 16.

[0038] The working principle and use process of the utility model are as follows: the plastic bag is spread flat in the detection installation groove 3, the hydraulic rod 4 is controlled to extend by the switch 10, the piston rod end of the hydraulic rod 4 pushes the pressing frame 6 down through the connecting bracket 5, the pressing frame 6 is pressed on the surface of the plastic bag, and the two side surfaces of the plastic bag are respectively in contact with the rubber frame 7 and the rubber pad 8, which can improve the sealing of the edge of the plastic bag, and the air pump 9 is controlled to work by the switch 10, and the air pump 9 can inject air into the plastic bag. The plastic bag expands under the action of the gas and lifts up the height detection cross bar 13. The two ends of the height detection cross bar 13 are lifted by the lifting mechanism. The lowering sleeve 12 is slidably connected to the guide column 11. The guide column 11 and the lifting sleeve 12 are matched to guide the lifting and lowering of the height detection cross bar 13. An expansion plate 14 is integrally formed in the middle of the height detection cross bar 13. The expansion plate 14 can increase the contact area between the height detection cross bar 13 and the plastic bag, so that the plastic bag can quickly lift the height detection cross bar 13 after expansion until the plastic bag breaks. The expansion size of the plastic bag can be measured by matching the scale 16 with the lifting sleeve 12, thereby realizing the Kuas detection of the ductility of the plastic bag.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
