[0049] Working principle of the present invention:

[0050] When performing a hair product droop test, the hair bundle to be tested is suspended by the hair bundle suspension mechanism 3, the hair bundle to be tested 28 is arranged to be straight, and a camera is used to capture the maximum cross-section of the hair product. The rotating mechanism 2 rotates the hair bundle to be tested 28 at a certain speed for a certain period of time, and then collects the cross-section of the hair product after it stops. The hair bundle to be tested 28 is then rotated by degrees, and the cross-section of the hair product is collected again. The diameters of the two collected cross-sections are averaged, and then the maximum cross-sectional areas of the hair product before and after the rotation are obtained by a digital image analysis method. The droop coefficient of the hair product is calculated, thereby measuring the droop of the hair product.

[0051] The specific operation is as follows: in a stationary state, the maximum radius of the cross section of the hair bundle 28 to be tested is measured as r1, after rotating for a period of time, it is stationary for 30 seconds, and the maximum radius of the cross section of the hair bundle 28 to be tested is measured as r2, and then it is rotated 90 degrees and r3 is measured.

[0052]

[0053] When testing the softness of hair products:

[0054] Speed ​​measurement method: first, the first cylinder 10 extends forward to insert the comb fixture 13 into the comb fixing frame 7, and the second driving module 6 drives the first cylinder 10 to move upward. After reaching a certain height, the first driving module 5 drives the second driving module 6 to move forward, so that the comb 27 is inserted into the hair bundle 28 to be tested, and a loading weight is placed on the comb fixing frame 7. Then, the first cylinder 10 retreats backward, the comb fixture 13 is separated from the comb fixing frame 7, and the second cylinder 26 moves downward. The piston rod of the second cylinder 26 contacts the comb 27, breaking the static friction state, so that the comb 27 slides downward. When the comb 27 descends, the timing device 9 will record the time required for it to descend to a certain height, and the smoothness rate is calculated, thereby measuring the softness of the hair product;

[0055] Force measurement method: the first cylinder 10 extends forward to insert the comb fixture 13 into the comb fixing frame 7, and the second driving module 6 drives the first cylinder 10 to move upward. After reaching a certain height, the first driving module 5 drives the second driving module 6 to move forward, so that the comb 27 is inserted into the hair bundle 28 to be tested, and the second driving module 6 drives the comb 27 to move downward at a constant speed. The weighing sensor 11 will obtain a maximum force value and a maximum resistance force from the beginning to the end of sliding down, and then an average force value and an average resistance force are obtained through software analysis, thereby measuring the flexibility of the hair product.
