Entrance to outlet resistance it is basically identical, material by cavity be square plate distribution head distribution, pass through the modeling of distribution head
Make, make its material exported thickness and width close to the thickness and width of slit material ejiction opening, cavity is made to be square plate
The material ejection pressure of the lower end outlet of the distribution head of shape everywhere is basically identical, ensure that the thickness of be coated with material is uniform.
Here, slit material ejiction opening is provided with thickness adjusting mechanism, and thickness adjusting mechanism includes forming slit ejection
The fixation wall of mouth one side, the movable wall for forming slit ejiction opening opposite side, are provided with fixed sidewall on the outside of movable wall, along admittedly
Determine side wall be uniformly distributed and slide through fixed sidewall several axis connections be provided on movable wall, on fixed sidewall band moving axis
The adjuster of back-and-forth motion.In use, by the position of adjuster adjustment axis, and then determine the thickness of slit, it is applied to adjust
The thickness of cloth.
Compared with the prior art the present invention, has the advantages that the in uniform thickness of the material of coating.
