[0057] This embodiment also proposes a paper water absorption test method. The test method is implemented using the above test device. The test method includes the following steps:

[0058] First, turn on the fill light 7, fit different test papers to the front of the cross bar 809, then squeeze the two rectangular blocks 911 inward at the same time to shrink them into the storage groove 909, then fit the second clamping plate 902 to the back of the cross bar 809, insert the short cylinder 906 into the small hole 811, and then make the plug plate 905 and the limit rod 904 pass through the rectangular groove 913 and the through hole 812 respectively, and insert them into the slot 908 and the limit hole 907. When the rectangular block 911 moves to the position of the through groove 914, the spring 910 pushes the rectangular block 911 to pop out from the through groove 914, so as to realize the assembly of the two clamping plates. At this time, the test paper is located between the two clamping plates, so the test paper is fixed, and then the motor 2 807 is started to rotate forward, and the motor 2 807 moves the cross bar 809 to the top of the liquid container 4 through the meshing of the gear 3 808 and the tooth plate 814, and then the motor 2 807 is turned off and the motor 1 804 is started to rotate forward, and the motor 1 804 drives the threaded rod 802 through the meshing of the gear 2 805 and the gear 1 803, and the threaded rod 802 drives the connecting rod 806, and the connecting rod 806 drives the cross bar 809 to move downward, and the cross bar 809 drives the test paper to move downward so that it is immersed in the liquid to perform the water absorption test;

[0059] Secondly, the weighing module 3 monitors the weight of the liquid container 4 in real time and converts the weight signal into an electrical signal and transmits it to the PLC 15. The PLC 15 compares the actual weight value with the preset weight, controls the start and stop of the infusion pump 12, and makes it introduce the liquid in the storage container 11 into the liquid container 4 to ensure that the liquid in the liquid container 4 is sufficient and the measurement accuracy is ensured;

[0060] Then, the camera 17 is turned on to record the process of absorbing liquid and feed it back to the upper computer interface of the computer, the pin 105 is pulled upward to disengage it from the small hole 106, and then the turntable 104 is rotated counterclockwise, the turntable 104 drives the rotating shaft 103, the rotating shaft 103 drives the connecting column 102, the connecting column 102 drives the connecting arm 107, and the connecting arm 107 drives the collecting box 110 to be located on the upper side of the liquid container 4, and then the motor 1 804 is started to reverse, so that the cross bar 809 rises, so that the test paper is separated from the liquid container 4, and then the motor 2 807 is started to move the cross bar 809 to the left side of the liquid container 4. The collecting box 110 is located at the bottom of the test paper and can collect dripping liquid to ensure the cleanliness of the equipment table;

[0061] Finally, turn off the fill light 7 and remove the lighting board 6 and repeat the above operation to perform the water absorption test without light, and compare and analyze the measurement data of the two groups.

One end of the hose (13) away from the infusion pump (12) is fixedly provided with a stainless steel corrugated pipe (14). On the front surface of the mounting frame (1), a PLC (15) is fixedly provided. On one side of the mounting frame (1), a support frame (16) is fixedly provided. On one side of the support frame (16), a camera (17) is fixedly provided.

10. A paper water absorption test method, characterized in that: The above test device is used to implement the test method, which includes the following steps: Turn on the supplementary light (7), fix different test papers on the cross bar (809), adjust the position of the cross bar (809) through the first motor (804) and the second motor (807), and immerse the test papers into the liquid in the liquid container (4) for water absorption test; The weighing module (3) monitors the weight of the liquid container (4) in real time and converts the weight signal into an electrical signal for transmission to the PLC (15). The PLC (15) controls the start and stop of the infusion pump (12) to pour the liquid in the storage container (11) into the liquid container (4), ensuring that the liquid in the liquid container (4) is sufficient. Turn on the camera (17), record the process of absorbing the liquid and feedback it to the upper computer interface on the computer side. Rotate the turntable (104) to position the collection box (110) above and to one side of the liquid container (4), and separate the test paper from the liquid container (4) by starting the first motor (804) and the second motor (807). The collection box (110) is positioned at the bottom of the test paper to collect the dripping liquid. Turn off the fill light (7) and remove the lighting panel (6), then repeat the above operation to conduct the water absorption test without light, and compare and analyze the measurement data of the two groups.
