At the same time, the adjusting mechanism can also adjust the position pressed by the pressing mechanism according to the size of the corrugated cardboard.

[0033] The pressing mechanism includes two dovetail grooves 8 opened on the top of the base 1. Two dovetail blocks 9 are slidably connected inside the dovetail grooves 8. The top of the dovetail blocks 9 is fixedly connected with a support frame 10;

[0034] A transverse chute 11 is opened on the top of the support frame 10. A sliding block 12 is slidably connected inside the transverse chute 11. A threaded rod 13 is threadedly connected to the surface of the sliding block 12. A threaded hole 14 for cooperating with the threaded rod 13 is opened on the top of the sliding block 12. The bottom of the threaded rod 13 is fixedly connected with a pressing block 15.

[0035] In this embodiment, considering that during the process of the strength tester pressing the corrugated cardboard, the phenomenon of the corrugated cardboard shifting will affect the detection accuracy. Therefore, by setting the pressing mechanism, after the corrugated cardboard is placed on the base 1, by sequentially rotating the four turning blocks 23, the threaded rod 13 is driven to rotate in the threaded hole 14. The threaded rod 13 will move downward, and at the same time drive the pressing block 15 and the anti-slip pad 25 to move downward, so that the bottom of the anti-slip pad 25 is in close contact with the top of the corrugated cardboard, achieving the pressing effect and avoiding the phenomenon of the corrugated cardboard shifting during the pressing process;

[0036] It solves the problem that considering that during the process of the strength tester pressing the corrugated cardboard, the phenomenon of the corrugated cardboard shifting will affect the detection accuracy.

At the same time, the rubber material of the anti-slip pad 25 can effectively play a buffering role.

[0041] Embodiment 2:

[0042] Based on Embodiment 1, in this embodiment, the pressing mechanism can press the corrugated cardboard to prevent the phenomenon of displacement during the detection of the corrugated cardboard. However, considering the different sizes of the corrugated cardboard, if it cannot be accurately pressed at the corners of the corrugated cardboard, it will also affect the pressing effect. In this application, the adjusting mechanism includes a housing 16 fixedly arranged on one side of the support frame 10. A moving block 17 is movably connected inside the housing 16. A positioning rod 18 is fixedly connected to the bottom of the moving block 17. The bottom of the positioning rod 18 penetrates to the bottom of the housing 16. A positioning hole 19 adapted to the positioning rod 18 is formed in the top of the base 1;

[0043] Push blocks 20 are fixedly connected to both sides of the moving block 17. Push grooves 21 adapted to the push blocks 20 are formed in both sides of the housing 16.

[0044] In this embodiment, considering the different sizes of the corrugated cardboard, if it cannot be accurately pressed at the corners of the corrugated cardboard, it will also affect the pressing effect. Therefore, by setting the adjusting mechanism, the push block 20 can be moved upward. The push block 20 will drive the moving block 17 and the positioning rod 18 to move upward, releasing the restriction on the support frame 10. Then, according to the size of the corrugated cardboard, the support frame 10 is pushed along the tracks of the dovetail groove 8 and the dovetail block 9 to adjust the longitudinal position. After reaching the appropriate position, the push block 20 is released. The elastic force generated by the spring 22 will push the moving block 17 and the positioning rod 18 downward, so that the positioning rod 18 enters the corresponding positioning hole 19. At the same time, the pressing position of the pressing block 15 can also be adjusted horizontally along the tracks of the transverse sliding groove 11 and the sliding block 12, so that the four pressing blocks 15 can be pressed at the corners of the corrugated cardboard, improving the pressing effect;

[0045] It solves the problem that considering the different sizes of the corrugated cardboard, if it cannot be accurately pressed at the corners of the corrugated cardboard, it will also affect the pressing effect.

[0046] A spring 22 is fixedly connected to the top of the push block 20. The top of the spring 22 is fixedly connected to the inner wall of the housing 16.

[0047] In this embodiment, by setting the spring 22, when the user releases the push block 20, the elastic force generated by the spring 22 can drive the moving block 17 and the positioning rod 18 to move downward, so that the positioning rod 18 enters the corresponding positioning hole 19, playing a role in resetting.

[0048] The number of the positioning holes 19 is several, and they are longitudinally and evenly distributed on the base 1.

[0049] In this embodiment, by uniformly arranging a plurality of positioning holes 19 on the base 1, after the position of the support frame 10 is adjusted, the positioning rod can be inserted into the corresponding positioning hole 19 to quickly limit the support frame 10.

[0050] Working principle: After the corrugated cardboard is placed on the base 1, by sequentially rotating the four screwing blocks 23, the threaded rod 13 is driven to rotate in the threaded hole 14. The threaded rod 13 will move downward, and at the same time drive the pressing block 15 and the anti-slip pad 25 to move downward, so that the bottom of the anti-slip pad 25 is in close contact with the top of the corrugated cardboard, achieving the pressing effect and avoiding the phenomenon of the corrugated cardboard shifting during the pressing process.

[0051] Considering that the sizes of corrugated cardboard are different, if it cannot be accurately pressed at the corners of the corrugated cardboard, it will also affect the pressing effect. Therefore, by setting an adjusting mechanism, the pushing block 20 can be moved upward. The pushing block 20 will drive the moving block 17 and the positioning rod 18 to move upward, releasing the restriction on the support frame 10. Then, according to the size of the corrugated cardboard, the support frame 10 is pushed along the tracks of the dovetail groove 8 and the dovetail block 9 to adjust the longitudinal position. After reaching the appropriate position, the pushing block 20 is released, and the elastic force generated by the spring 22 will push the moving block 17 and the positioning rod 18 downward, so that the positioning rod 18 can enter the corresponding positioning hole 19. At the same time, the position where the pressing block 15 presses can also be adjusted horizontally along the tracks of the transverse sliding groove 11 and the sliding block 12, so that the four pressing blocks 15 can press on the corners of the corrugated cardboard, improving the pressing effect.
