[0038] When the absorbent core is placed in the detection box 2, the tray 34 is used to support the absorbent core to prevent it from falling out of the through hole 4. When the lifting seat 5 moves down, the pressing ring 30 located below the lifting seat 5 presses the absorbent core. As the lifting seat 5 continues to move down, the distance between the pressing ring 30 and the lifting seat 5 becomes smaller, and the compression spring 33 applies pressure to the pressing ring 30 so that the absorbent core is fixed between the pressing ring 30 and the bottom inner wall of the detection box 2.

The staff drives the collecting barrel 39 to move up so that the bottom end of the collecting barrel 39 is separated from the positioning ring 45, and the collecting barrel 39 can be removed from the operating table 1.

[0039] A method for online detection of an absorbent core of this embodiment uses the above-mentioned device for online detection of an absorbent core, and comprises the following steps:

[0040] Step 1: Place several absorbent cores to be tested in the corresponding test boxes 2 respectively, and support the absorbent cores located above the through holes 4 by supporting the collection assembly;

[0041] Step 2: The lifting seat 5 is driven to move down to a preset position by the first hydraulic telescopic rod 6, the absorbent core in the detection box 2 is fixed by the core pressing unit on the lifting seat 5, and then the absorbent core in the detection box 2 is sprayed with water by the water spray detection component;

[0042] Step 3: The water that cannot be absorbed by the absorbent core flows out through the through hole 4, and the water flowing out through the through hole 4 is collected by the support collection component;

[0043] Step 4: The water absorption of the absorbent core is detected by calculating the difference between the water sprayed by the water spray detection component and the water collected by the support collection component, and multiple groups of absorbent cores are detected simultaneously.

[0044] Working principle: During operation, several absorbent cores to be tested are placed in the corresponding test box 2 respectively, and the absorbent core located above the through hole 4 is supported by the support and collection assembly, and the lifting seat 5 is driven to move down to the preset position by the first hydraulic telescopic rod 6, and the absorbent core located in the test box 2 is fixed by the core pressing unit on the lifting seat 5, and then the absorbent core located in the test box 2 is sprayed with water by the water spraying test assembly, and the water that cannot be absorbed by the absorbent core flows out through the through hole 4, and the water flowing out through the through hole 4 is collected by the support and collection assembly, and the water absorption of the absorbent core is detected by calculating the difference between the water sprayed by the water spraying test assembly and the water collected by the support and collection assembly, and multiple groups of absorbent cores are tested simultaneously, which reduces the time used for testing and improves the testing efficiency;

[0045] When the lifting seat 5 is lowered to the preset position, the first tension spring 18 is initially in a tensioned state, and the first tension spring 18 applies tension to the movable seat 14 and the support column 16, so that the end of the support column 16 away from the movable seat 14 is in close contact with the inner wall of the slide groove 22, and the motor 21 drives the turntable 19 to rotate, so that the end of the support column 16 slides on the inner wall of the slide groove 22, thereby making the support column 16 and the movable seat 14 reciprocate horizontally relative to the lifting seat 5, and the movable seat 14 drives the water outlet pipe 8 to reciprocate horizontally through the movable box 7, and the movable box 7 drives the guide column 46 to slide relative to the support block 47. The design of the guide column 46 and the support block 47 allows the movable box 7 to move smoothly in the horizontal direction, and at the same time, the water outlet pipe 8 drives The gear 11 rolls on the tooth plate 12 to make the water outlet pipe 8 drive the branch pipe 9 to rotate, that is, the water outlet pipe 8 moves horizontally while the water outlet pipe 8 rotates, changing the position of the water spray head 10, driving the lifting frame 28 and the first connecting column 29 to move upward through the second hydraulic telescopic rod 27, and the first connecting column 29 drives the piston plate 26 to move upward, and the piston plate 26 pushes the water in the water tank 23 into the movable box 7 through the hose 24, and the water then enters the branch pipe 9 through the water outlet pipe 8, and finally the water is sprayed toward the absorbent core through the water spray head 10. Since the position of the water spray head 10 is changed, the water can be sprayed evenly on the absorbent core. After the detection is completed, the valve on the water inlet pipe 25 is opened, and water can be added to the water tank 23 through the water inlet pipe 25;

[0046] When the absorbent core is placed in the detection box 2, the tray 34 is used to support the absorbent core to prevent it from falling out of the through hole 4. When the lifting seat 5 moves down, the pressing ring 30 located below the lifting seat 5 presses the absorbent core. As the lifting seat 5 continues to move down, the distance between the pressing ring 30 and the lifting seat 5 becomes smaller, and the compression spring 33 applies pressure to the pressing ring 30 so that the absorbent core is fixed between the pressing ring 30 and the bottom inner wall of the detection box 2. As the lifting seat 5 continues to move down, the lifting seat 5 contacts the top of the second support frame 38, and the lifting seat 5 pushes the second support frame 38, the water collecting bucket 35 and the second movable column 40 to move down. The second movable column 40 drives the fixed plate 43 to move down, the second tension spring 44 is in a tensioned state, and the water collecting bucket 35 drives the tray 34 to slide out of the through hole 4 through the second connecting column 36, and the top of the stop column 37 no longer contacts the bottom of the detection box 2. When the water outlet of the water collecting bucket 35 is inserted into the collecting barrel 39, the water that the absorbent core cannot absorb flows into the collecting barrel 39 through the water collecting bucket 35. When no detection is needed, the first hydraulic telescopic rod 6 drives the lifting seat 5 to move up to the initial position, and the second tension spring 44 drives the fixed plate 43 and the second movable column 40 to move up, so that the water outlet of the water collecting bucket 35 is pulled out of the collecting barrel 39, and the tray 34 is inserted into the through hole 4, and the top of the stop column 37 contacts the bottom of the detection box 2. The water collecting bucket 35 and the tray 34 move up to the initial height and then stop. As the lifting seat 5 continues to move upward, the pressing ring 30 no longer presses the absorbent core, and finally the pressing ring 30 is pulled out of the detection box 2, and the staff can take out the absorbent core located in the detection box 2 and supported by the tray 34. The staff drives the collecting barrel 39 to move up so that the bottom end of the collecting barrel 39 is separated from the positioning ring 45, and the collecting barrel 39 can be removed from the operating table 1.
