This invention relates to a material conveying device for ramie textile processing, belonging to the field of textile machinery technology. It includes a machine body, a connecting frame mounted on one side of the machine body, a support plate mounted on the connecting frame near the machine body, multiple sets of guide holes at the top of the support plate, and a guide frame mounted on the side of the support plate away from the connecting frame. The guide frame is installed at an angle, and multiple sets of guide tubes are mounted on the top of the guide frame. A de-hairing component is mounted on the machine body near the guide frame. This invention, through the inclusion of a cleaning component, allows the collection mechanism, once full of impurities, to automatically flip into a washing tank for rinsing and cleaning. The filter plate achieves solid-liquid separation, facilitating centralized treatment of burrs. By setting up an integrated de-hairing and collection structure, and utilizing a fan and air holes to create a negative pressure airflow, it can efficiently adsorb free burrs, short fibers, and impurities on the surface of ramie fibers.
