[0030] Further, the frame support 1 has a replacement opening 36 for replacing the foam collecting box 33, and the foam collecting box 33 has a handle 331. The replacement opening 36 can replace the full foam collecting box 33 for continuing the subsequent test.

[0031] Further, the light box 4 is provided with a light transmission window 41 on one side close to the evaluation board 31. The light box 4 is built-in with D65 standard light source, the inside is black, and the light transmission window 41 is opened in the direction of the evaluation board 31. The light transmission window 41 can transmit light, and it and the internal light source are in a relatively sealed state, so that liquid cannot enter the light box 4. When the foam is sprayed on the outer plate of the light box 4, the LUX luminosity value is read by using the luminosity meter as the data of the foam concentration.

[0032] Principle: First, the evaluation board 31 (may have a variety of evaluation board 31) is installed on the test fixture 3 and fixed by limiting the fixed plate 32, then the foam collection tank 33 is placed on the mounting plate 35 (ie foam substrate) by replacing the mouth 36 or other ways, foam collection tank 33 needs to be emptied before installation foam collection tank 33 inside, at this time the foam collection tank 33 will be right below the evaluation board 31, will be used to collect the foam from the evaluation board 31 down, the light box 4 light source is turned on, you can see the light through the light window 41.

[0033] The foam spray pot (ie cleaning liquid pot 7 and high pressure spray gun 564) is filled with the required cleaning agent, and the weight is weighed and recorded, then the measured spray pot is connected with the high pressure spray gun 564 and erected on the clamping tool, the clamping tool is locked to fix, then the nozzle of the high pressure spray gun 564 is adjusted to the appropriate distance of the evaluation board 31 by moving the third guide 55 on the vertical guide 54, and the position relationship in the front and back direction is locked by the locker 531, if the adjustment distance is small, the fine adjustment of the clamping tool can also be implemented, if the adjustment distance is large, the adjustment needs to be extended, the front and back position adjustment can be realized by adjusting the first guide 52 on the longitudinal guide 51, then the lowest position of the spray pot is adjusted to the lower edge of the evaluation board 31 by adjusting the vertical position of the third guide 55 on the vertical guide 54, then the adjusted position is fixed by the locker 531.

[0034] Start running control box 2 to activate the motor control unit, drive the set drive motor 561 to drive the left and right movement speed and the number of movements of the clamping tool, then connect the high pressure water pipe to the measured foam spray pot, get the pressure and flow information in the high pressure water pipe by external pressure and flow sensor, give the foam pot high pressure water, the foam pot starts to spray foam, at this time start the switch in the running control box 2, the transverse drive guide 56 runs at the set speed and times, the running control box 2 stops running after reaching the set running result, at this time stop supplying water to the high pressure water pipe to stop the foam dispersion.

[0035] At this time, the foam sprayed on the evaluation board 31 by the foam spray bottle will start timing, and the time of the foam flowing on the evaluation board 31 will be used as a performance judgment basis. The basis for judging the end of the flowing is that no visible foam falls from the evaluation board 31. Immediately after timing, the light intensity value of the foam under the shielding of the foam is read through the light transmission window 41 by using the light intensity measuring instrument and recorded. The minimum light intensity value is read and recorded. After the flowing ends, the flowing time is recorded. The flowing time will be used as a performance judgment basis. At the same time, the volume of the foam falling into the foam collection box 33 is measured. The volume change is recorded every minute for 5 minutes to obtain the retention rate percentage of the foam. The foam retention rate will be used as a performance judgment basis. The weight of the foam spray bottle after the test is weighed again and recorded. The consumption of the cleaning agent per unit time can be obtained through the flow value in the high-pressure pipe and the weight reduction of the cleaning bottle. The cleaning agent consumption will be used as a performance judgment basis. Finally, the spray angle of the foam spray bottle is also measured and recorded. The angle will be used to calculate the time required for spraying at a specific moving speed to complete a specific area. This time will be used as a performance judgment basis. Finally, the total score value is calculated through the numerical relationship of each evaluation basis to obtain the performance of each foam.
