Residual liquid removing device for warp beam sizing

The residual liquid removing device comprises a rectangular frame with openings in the left side and the right side, a liquid receiving groove is movably formed in the rectangular frame, a transmission column is horizontally arranged above the liquid receiving groove in the front-back direction, bearings are arranged at the two ends of the transmission column in a sleeved mode, and the bearings are connected with the liquid receiving groove in a sleeved mode. And telescopic mechanisms vertically fixed in the rectangular frame are arranged on the bearings, an upper disc is coaxially and fixedly arranged on the transmission column, and a rotating column arranged on the rectangular frame through a rotating shaft is arranged under the transmission column in parallel. According to the residual liquid removing device for warp beam sizing, when residual liquid on sized yarn is removed, the residual liquid on the warp can be removed, so that the risk that the residual liquid drips everywhere is reduced, and the warp
