The equipment is designed and developed with advanced concept. The equipment is composed of single end coating machine and dryer. It is used for gluing the end of aluminum air conditioning pipe fittings. Single head coating machine: the machine is suitable for coating various complex pipe fittings such as straight pipe, elbow and long pipe. The glue liquid is added automatically. One end is coated for about 2 ~ 3S. The foot switch acts once and the coating is applied once. Dryer: the dryer is designed to be rotary (the diameter of the rotary table is about) Φ 950) there are 32 stations in total, which are divided into three areas: feeding area, high-temperature drying area and cold air area. The hot air power is 6kW, the heating temperature is adjustable to 200 ℃, and the rotating speed of rotary table is 0.1 ~ 0.53r/min.
