Abstract

The invention discloses a drying box wind nozzle for colored coating. The drying box wind nozzle comprises an upper shell, a draught fan, a heating mantle, a ventilating duct, a positive pressure cavity, wind nozzle bodies, a lower shell and guide wheels. The heating mantle is arranged between the draught fan and the ventilating duct. The ventilating duct is of a hollow structure and is further arranged above the upper shell, and the ventilating duct communicates with the upper shell. The positive pressure cavity communicating with the ventilating duct is formed in the upper shell. The multiple wind nozzle bodies are arranged at the lower end of the positive pressure cavity. The sides, making contact with the positive pressure cavity, of the wind nozzle bodies and the sides, opposite to the positive pressure cavity, of the wind nozzle bodies are both provided with openings. End faces are arranged at the two ends, perpendicular to the side faces of the corresponding opening, of each wind nozzle body. The wind nozzle bodies are obtained in a punch-forming mode. The wind nozzle bodies extend out of the upper shell. The lower shell is located below the wind nozzle bodies, and the multiple guide wheels are arranged at the upper end of the inside of the lower shell. The problem that membranes are shaded after being dried by an existing wind nozzle can be effectively solved, and the wind nozzle strength is guaranteed.

Description

Technical field [0001] This application relates to the technical field of film product drying, in particular to an oven air nozzle for colored coating. Background technique [0002] After the film is processed, it needs to be dried and shaped into a finished product for use. At this time, it needs to be dried in an oven, such as figure 1 As shown, the overall oven is divided into upper and lower parts. The upper part mainly includes a fan, a heating pack, a positive pressure cavity and a tuyere; the lower part mainly includes a guide wheel. Turn on the heating pack and the fan to provide hot air for drying, and blow the hot air out through the nozzle. The film to be dried after processing is placed above the guide wheel, and through the rolling action of the guide wheel, the film is continuously driven in the oven, and finally the whole film is blown dry by the air nozzle in the oven. [0003] The nozzle of the existing oven is generally designed with a length of 1m, a width of 3m...
