[0027] During use, when discharging the mixed powder coating, since its flow rate is not high, there will be some dry hanging on the inner wall of the discharge pipe, thus blocking the discharge pipe and causing difficulties in discharging. Therefore, for the mixing equipment of outdoor low-temperature curing powder coatings, when discharging is required after the mixing is completed, the mixed material flows into the interior of the first discharge pipe 17 through the discharge port 16. At this time, the third motor 20 is started, causing the auger 19 to start rotating. Through the setting of the auger 19, the coating can be quickly discharged, achieving the purpose of facilitating discharge, so that the mixed material quickly flows from the back to the front above the second discharge pipe 18 and then flows out of the interior of the second discharge pipe 18. Through the combined setting of the first heat-insulating cotton 21 and the second heat-insulating cotton 22, the cooling speed of the coating during its flow inside the discharge pipe can be slowed down.
