附件为NQR线模头排风罩的图纸，现在的模头排风罩与A-M线的模头排风罩

The attachment is the drawing of the die exhaust hood of the NQR line. The current die exhaust hood has a completely different structure from that of the AM line. The flow deflector of the die exhaust hood was originally arranged in the vertical direction of the film. And it is in a trapezoidal layout. The current die exhaust hood deflector layout has become parallel to the film running direction, and is arranged in a plane. There is a 20mm gap between the deflectors. Please confirm the die exhaust hood drawing by the project manager No errors, and inform the reason for changing the design.

Accessories for the NQR line head exhaust cover drawings, the current die exhaust cover and A-M line die exhaust cover structure form is completely different, the mold head exhaust cover of the deflect plate layout was originally vertical membrane running direction, and a trapezoidal arrangement Now the die exhaust shield guide plate layout has become parallel to the membrane running direction, and is a flat layout, there is a gap of 20mm between the deflect plate, please project manager to confirm that the die exhaust cover drawings are correct, and inform the reasons for changing the design.

附件为NQR线模头排风罩的图纸，现在的模头排风罩与A-M线的模头排风罩结构形式完全不同，模头排风罩的导流板布置原先为垂直膜运行方向，且呈梯形布置，现在的模头排风罩导流板布置变为了平行于膜运行方向，且呈平面排布，导流板之间有20mm的缝隙，请项目经理确认模头排风罩图纸无误，并告知更改设计的原因。<br>
