Specific embodiment
In order to improve the flatness of the film layer that coating is formed, Improving The Quality of Products, this utility model embodiment provides one
Plant coating nozzles and coating machine.For making the purpose of this utility model, technical scheme and advantage clearer, right by the following examples
This utility model is described in further detail.
Refer to Fig. 1, Fig. 2, Fig. 3, a kind of embodiment of this utility model provide coating nozzles, including nozzle chambers 1 and with
The flat-shaped mouthpiece 2 of nozzle chambers 1 connection, the A/F at flat-shaped mouthpiece 2 two ends is more than the A/F of mid portion.
In the coating nozzles that this utility model embodiment provides, the A/F at flat-shaped mouthpiece two ends is more than mid portion
A/F, compared to existing technology, embodiment of the present utility model passes through the film of the suitable coating increasing coating nozzles two ends
The amount of material, thus be coated with the uniformity of membrane material to improve coating nozzles, and then improves the flatness of film layer, improves product
Quality.
As shown in Fig. 2 in a preferred embodiment of the present utility model, the opening at flat-shaped mouthpiece two ends is tubaeform
Opening.
As shown in figure 3, in another preferred embodiment of the present utility model, the opening at flat-shaped mouthpiece two ends is trapezoidal
Opening, the longer base of described trapezoid-shaped openings is away from the mid portion of flat-shaped mouthpiece.
