[0036] Working principle or structural principle: First, according to the proportioning requirements, prepare an appropriate amount of phase change material, and then prepare the MMA coating for mixing, ensuring its compatibility with the phase change material. Add the phase change material for producing the MMA coating from the feed pipe 12 into the proportioning tank 2. Then, add stabilizers and thickeners into the proportioning tank according to requirements. Then start the motor 41. The output end of the motor 41 drives the driving bevel gear 42 to rotate. The rotation of the driving bevel gear 42 drives the driven bevel gear 43 at the upper end to rotate. The rotation of the driven bevel gear 43 drives the driving rotating shaft 44 to rotate. The rotation of the driving rotating shaft 44 drives the first pulley 45 to rotate. The rotation of the first pulley 45 drives the first transmission belt 46 to rotate.

The rotation of the hollow tube 48 drives the connecting rod 49 to rotate. The rotation of the connecting rod 49 drives the slider 410 to slide on the hollow rod 411, and at the same time drives the hollow rod 411 to rotate. The rotation of the hollow rod 411 drives the stirring rod 412 to rotate. The rotation of the stirring rod 412 drives the first stirring blade 413 and the scraper 414 to rotate to stir the materials for producing the MMA coating in the proportioning tank 2.

Then finally start the solenoid valve 11 to discharge the phase change material with completed stirring and proportioning from the discharge pipe 10. And when it is necessary to clean the inside of the proportioning tank 2, the water pump 7 can be started. The water pump 7 pumps the clean water in the water tank 6 into the water outlet pipe 8. Then the water outlet pipe 8 conveys the water from the hollow tube 48 to the spray head 415 to perform rotary spraying cleaning on the inside of the proportioning tank 2 in cooperation with the rotation of the hollow tube 48.
