[0019] The embodiment of the present application provides a compressive strength testing device for the production of easy-open lids, which effectively solves the problem that the easy-open lids cannot be effectively clamped by only two groups of magnets, so that the easy-open lids may move or shake during the test, resulting in inaccurate test results. The easy-open lids to be tested are placed in the testing table 4. At this time, rotating the screw 9 will drive the two blocks 8 sleeved thereon to move toward the opposite sides. The two blocks 8 can limit and fix the easy-open lids during the movement. At this time, the controller 2 controls the pressure sensor 6 to descend to perform strength testing on the easy-open lids. This structure can prevent the easy-open lids from moving or sliding when subjected to pressure, ensuring that the pressure acts evenly on the test area, thereby improving the repeatability and reliability of the data.

[0020] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that only two sets of magnets cannot be used to effectively clamp the easy-open lid, so that the easy-open lid may move or shake during the test, resulting in inaccurate test results. The overall idea is as follows:

A connecting plate 11 is fixedly connected to the lower surface of the testing platform 4. The connecting strip 13 is fixedly connected to the connecting plate 11. A screw rod 2 17 is threadedly sleeved on the inner thread of the positioning block 20. The screw rod 2 17 is threadedly sleeved on the connecting block 18. The easy-open lid to be tested is placed inside the testing platform 4. At this time, rotating the screw rod 9 will drive the two card blocks 8 sleeved thereon to move toward the opposite sides. The two card blocks 8 can limit and fix the easy-open lid during the movement. At this time, the controller 2 controls the pressure sensor 6 to descend to perform strength testing on the easy-open lid.

[0022] A limit block 15 is fixedly connected to the upper surface of the connecting strip 13, and the limit block 15 is slidably connected to the card strip 12. An L-shaped block 14 is fixedly connected to the right surface of the pressure sensor 6, and the L-shaped block 14 is slidably connected to the connecting strip 13. This structure can prevent the easy-open cover from moving or sliding when subjected to pressure, ensuring that the pressure acts evenly on the detection area, thereby improving the repeatability and reliability of the data.

[0023] A card block 8 is movably connected in the two card slots 7, and the two card blocks 8 are threadedly sleeved with the screw rod 1 9. Two T-slots 19 are provided on the upper surface of the fixed plate 3, and two T-blocks 10 are fixedly connected to the lower surface of the connecting plate 11. The two T-blocks 10 are slidably connected to the two T-slots 19 respectively. The screw rod 2 17 is rotated to open the limit of the positioning block 20 and the connecting block 18. At this time, the connecting block 18 can drive the pressure sensor 6 to move. An L-block 14 is fixed on the right surface of the pressure sensor 6. The L-block 14 will drive the connecting strip 13 to move together during the movement. The lower surface of the connecting strip 13 is fixedly connected with the connecting plate 11, and the connecting strip 13 is slidably connected to the card strip 12 through the limit block 15 fixed thereon. Through this structure, the length can be adjusted to make the device more flexible, and flexible adjustment can be made to meet the needs of use.

[0024] Working principle:

[0025] The easy-open lid to be tested is placed in the testing table 4. At this time, rotating the screw 1 9 will drive the two blocks 8 sleeved thereon to move toward the opposite sides. The two blocks 8 can limit and fix the easy-open lid during the movement. At this time, the pressure sensor 6 is controlled to descend by the controller 2 to perform strength detection on the easy-open lid. This structure can prevent the easy-open lid from moving or sliding when under pressure, ensuring that the pressure acts evenly on the detection area, thereby improving the repeatability and reliability of the data. Rotating the screw 2 17 opens the limit of the positioning block 20 and the connecting block 18. At this time, the connecting block 18 can drive the pressure sensor 6 to move. An L-shaped block 14 is fixed on the right surface of the pressure sensor 6. The L-shaped block 14 will drive the connecting strip 13 to move together during the movement. The lower surface of the connecting strip 13 is fixedly connected to a connecting plate 11.
