Description

Technical Field

[0001] This utility model relates to the field of aramid processing technology, specifically to an aramid short fiber beating device. Background Technology

[0002] Aramid staple fiber possesses excellent properties such as high strength, high modulus, and high temperature resistance, and is widely used in aerospace, defense, transportation, and other fields. In the processing of aramid staple fiber, beating is an important step. Its purpose is to treat the aramid staple fiber through mechanical action, causing the fiber to split and broom, thereby increasing the specific surface area and flexibility of the fiber and improving the bonding force between fibers to meet the requirements of subsequent papermaking, textile and other processing technologies.

[0003] The prior art patent document CN216631129U provides a pulping device for para-aramid pulp. By setting up a stirring paddle and a crushing mechanism, the pulp can be crushed while being stirred, integrating crushing and pulping into one, reducing space occupancy and improving processing efficiency.

[0004] The existing technology described above can crush and pulp aramid fibers, but it only crushes them during feeding, resulting in limited crushing effect. Furthermore, once the fibers enter the mixing process, the device can only mix in one direction, which can easily lead to localized fiber agglomeration and uneven dispersion, resulting in poor overall mixing effect. It also cannot continuously crush and refine the fibers. Therefore, we need an aramid short fiber beating device. Utility Model Content
