Beam sizing machine suitable for producing yarn dyed sizing

The utility model discloses a beam sizing machine suitable for producing yarn dyed sizing, which comprises a coiling headstock, a dry leasing device, a tension waxing device, a main drying room, parallel double size vats, a dyed yarn pre-drying room, beam creels and a complete machine transmission and control system. The beam sizing machine is characterized in that the beam creels are in two-group movable structure; each movable beam creel is provided with a dragging motor and a movable wheel set; and ground racks of two-group beam creels are arranged in a reversed L-shape or in a straight line shape. The beam sizing machine has the advantages that the beam creels are characterized by adopting two-group alternate movable type of beam creels, the problem that production time is occupied due to the beam creels being frequently hoisted up and down can be solved, continuous production between varieties is realized, and the production efficiency is improved; loose type warping beams can be directly and intensively put on the beam creels of the sizing machine for sizing, a multifunctional compound chuck is designed, and the problems of clamping and loading various loose type beam creels can be solved; multiple units are adopted for synchronous control, multiple yarn tension differences between size vats because of differences of total wrap numbers of two size vats can be eliminated, and tension of each area can be automatically controlled.
