1results about How to "Reduced form requirements" patented technology

The application discloses a mixed spraying layer, a non-woven composite material preparation device and a non-woven composite material, and relates to the technical field of composite material manufacturing. The mixed spraying layer preparation device comprises an opening and mixing device, a driving device, a feeding amount control device, a fiber distribution device, a conveying assembly, a mixed spraying box and a polymer system. The driving device is used for driving the fibers discharged from the opening and mixing device to the feeding amount control device and feeding the fibers into the fiber distribution device through the feeding amount control device. The fiber distribution device is provided with a height detection device. The fiber distribution device can distribute the fibers along the width direction and discharge the distributed fibers through a discharge port. The conveying assembly conveys the fibers discharged from the discharge port of the fiber distribution device into the mixed spraying box. The polymer system is used for producing polymer filaments and spraying the polymer filaments into the mixed spraying box. The application can use short fibers to manufacture the composite material, and the quality of the manufactured product is good.
