▎ 摘　　要

NOVELTY - The ultrasonic directional film forming device has a machine frame sequentially provided with a low-frequency vibration roller (2), a large-amplitude roller set (4) and a small-amplitude roller set (3) along the movement direction of the base film (1). The vibration frequency of the low-frequency vibration roller (2) is 5-10KHZ, and the vibration mode is vertical vibration along the movement direction of the base film, and the vibration amplitude is 10-30 micrometer. The vibration frequency of the large-amplitude roller set is 20-30KHZ, the vibration mode is that the large-amplitude roller set vibrates left and right in a direction parallel to the movement direction of the base film, and the amplitude is 5-10 micrometer. The vibration frequency of the small-amplitude roller set is 20-30KHZ, the base film is parallel to the motion direction and vibrates left and right in vibration mode, and the amplitude is 1-5 micrometer. USE - Ultrasonic directional film forming device. ADVANTAGE - The device has high universality and has high directional arrangement orderliness of the fillers. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a directional film forming method of composite material film. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of ultrasonic directional film forming device. 1Base film 2Low-frequency vibration roller 3Small-amplitude roller set 4Large-amplitude roller set 31Small amplitude ultrasonic source 32Small amplitude amplitude transformer 33First small amplitude roller 34Second small amplitude roller 41Large amplitude ultrasonic source 42Large amplitude variable amplitude rod 43First large amplitude roller 44Second large amplitude roller
