Advantages of coater drying

The coater comprises a frame, a back roll mechanism, a feeding roll mechanism, a hopper mechanism and a scraper arranged on the frame. The hopper mechanism of the product is an inverted trapezoid cylinder structure, an inverted triangular cylinder structure or a half cylinder structure, and the hopper mechanism is equipped with coating agent; the feeding roller mechanism of the product is infiltrated and fixed in the hopper mechanism; by changing the column shape of the feeding mechanism and improving the height of the feeding mechanism on the rack, the height of the feeding roller is not easy to be lower than the coating agent liquid level, so as to ensure the coating efficiency, The coating machine has the advantages of simple and reasonable structure, high and even coating efficiency, and convenient cleaning. The drying path of the coater includes a multi-stage cascade oven and a conveying device for conveying the coating material through each oven, and each oven is provided with an air nozzle for blowing the coating material to the conveying device The air nozzle in a section of oven is a single-sided blowing air nozzle. The single-sided blowing air nozzle of the product is staggered on and off the conveying device along the conveying direction of the conveying device in the oven. The blowing directions of each single-sided blowing air nozzle are the same or opposite to the conveying direction of the conveying device. The drying channel of the coater adopts the combination of one-sided blowing nozzle and two-sided blowing nozzle to dry the coating material. After the coating of the substrate, the one-sided blowing nozzle is used to dry the coating material directly, which improves the drying efficiency of the size and ensures the uniformity of the size.
