Coating equipment for super-bright polyester yarns

The coating equipment comprises a supporting frame, a rotating cylinder rotationally arranged on the supporting frame and a driving assembly for driving the rotating cylinder to rotate, and the rotating cylinder comprises an outer cylinder, an inner cylinder allowing the polyester yarn to penetrate through and a discharging cavity located between the outer cylinder and the inner cylinder and used for containing bright coating; brush bristles are distributed on the inner cylinder and face an inner cavity of the inner cylinder, the roots of the brush bristles are located in the discharging cavity, and the rotating cylinder is provided with a feeding end used for adding bright paint into the discharging cavity. And the rotating drum rotates to drive the bristles to coat the outer walls of the polyester yarns with the bright paint, so that the outer surfaces of the polyester yarns are uniformly coated with the bright paint, and the polyester yarns have better brightness. 本申请涉及一种超光亮涤纶丝的涂料设备，包括支撑架、转动设置于支撑架上的转筒以及驱动转
