[0002] Pearl cotton, also known as expanded polyethylene, is a lightweight, soft material with good cushioning properties. Pearl cotton (EPE) is widely used in packaging, transportation and other fields due to its excellent cushioning and shock absorption properties. In order to ensure that its shock absorption performance meets the expected standards, it is usually necessary to test its shock absorption performance. However, the existing pearl cotton shock absorption performance test usually indirectly derives the shock absorption performance of pearl cotton by testing the density and hardness of pearl cotton. This test method is not intuitive and accurate enough, and it is difficult to ensure the reliability of pearl cotton in actual use.

[0003] Therefore, a device and method for detecting the shock absorbing performance of pearl cotton have been developed, which can intuitively and accurately detect the shock absorbing performance of pearl cotton and ensure the reliability of the pearl cotton during actual use.

The displacement sensor monitors the displacement change between the connecting ring and the frame, and the shock absorption performance of the pearl cotton is obtained through the displacement change between the connecting ring and the frame.

[0015] The beneficial effects of the present invention are as follows: 1.

[0031] A device and method for detecting shock absorption performance of pearl cotton, such as Figure 1-Figure 9 As shown, it includes a base 0, a column 1, a horizontal platform 2, a vibration mechanism 3 and a detection mechanism 4. The base 0 has two left and right parts. The front and back parts of the base 0 are both provided with left and right mounting holes for easy installation and fixation. The upper side of the middle part of the base 0 is connected with the column 1, and the horizontal platform 2 is connected between the bases 0. The vibration mechanism 3 is arranged on the horizontal platform 2, and the detection mechanism 4 is also arranged on the horizontal platform 2.

[0034] When using the present invention, firstly, the base 0 is placed in the pearl cotton shock absorption performance detection area, and then the pearl cotton to be detected is placed on the vibration table 35, so that the contact plate 46 is placed on the upper side of the pearl cotton, and then the motor 31 is started to drive the straight rod 32 and the curved wheel 33 to rotate, so that the adjusting bolt 34 pushes the vibration bottom plate 36 to move up and down in the column 1 to knock the vibration table 35, so that the vibration table 35 vibrates, and the vibration is transmitted to the pearl cotton, and then transmitted to the cotton contact plate 46 and the conduction block 45 through the pearls, so that the connecting ring 42 moves on the stand 41, and the displacement sensor 43 monitors the displacement change between the connecting ring 42 and the stand 41.

By changing the position of the adjusting bolt 34 between the curved wheel 33, the movement amplitude of the vibration bottom plate 36 can be adjusted, thereby adjusting the vibration amplitude of the vibration table 35, so as to simulate various vibration conditions that may occur in the actual use environment.

[0035] like Figure 1 and Figure 7 As shown, it also includes a clamping mechanism 5, which includes a fixed seat 51, a centrifugal plate 52, a push column 53, a compression spring 54, a fixed plate 55, a fixed cross bar 56, a torsion spring 57, a flip table 58, an adjusting screw 59 and a lifting clamp 510.

The push columns 53 are connected to the connected fixed plates 55. There is a compression spring 54, and the upper sides of the left and right parts of the horizontal platform 2 are connected with a fixed cross bar 56, the fixed cross bar 56 is located inside the fixed plate 55, the front and rear parts of the fixed cross bar 56 are rotatably connected with a turning platform 58, and the turning platform 58 is connected to the connected fixed cross bar 56 with a torsion spring 57, the push column 53 is squeezed and matched with the adjacent turning platform 58, and the upper side of the turning platform 58 is rotatably connected with an adjusting screw 59, and the adjusting screw 59 is threadedly connected with a lifting splint 510, and the lifting splint 510 is slidably connected to the adjacent turning platform 58.

[0036] The clamping mechanism 5 of the device can be used to clamp the pearl cotton. When the curved wheel 33 rotates, the centrifugal plate 52 on the fixed seat 51 rotates and opens, pushing the push column 53 to move on the fixed plate 55, and the compression spring 54 is squeezed and contracted. The push column 53 pushes the turning table 58 to rotate, and the torsion spring 57 is deformed, so that the lifting clamp plate 510 clamps the pearl cotton, thereby fixing the pearl cotton on the vibration table 35 to prevent the pearl cotton from moving.

[0040] The dust cleaning mechanism 7 of the device can be used to remove dust. After the pearl cotton is placed on the vibration table 35, the fan 72 on the side plate 71 is started to blow air, thereby removing dust and other impurities on the pearl cotton to avoid affecting the detection results.

[0041] like Figure 1 and Fig. 9 As shown, it also includes a load-bearing mechanism 8, which includes an outer ring 81 and a load-bearing hook 82.
