The yarn end is drawn to a drying box yarn fixer of the automatic yarn arranging mechanism 7 for yarn drying, a plurality of yarns are fixed, the yarns are arranged on a drying box screw rod barrel 402 along with the rotation of the drying box screw rod barrel 402, and meanwhile, a blower arranged at a hot air drum inlet 408 sends hot air into an automatic drying mechanism rack 407 from the hot air drum inlet 408, so that when the yarns are drawn from one side to the other side, liquid contained in the yarns is fully volatilized, and the yarns are kept dry.

As shown in fig. 1, 4 and 13, the yarn collecting guide 8 includes a yarn collecting guide frame 1301, a yarn collecting wheel 1302 and a yarn collecting rotary shaft 1303. The yarn collecting guide rack 1301 is fixedly arranged at the top of the automatic drying and yarn arranging mechanism 7. The two yarn collecting wheels 1302 are respectively and fixedly arranged on two yarn collector rotating shafts 1303, and the yarn collector rotating shafts 1303 are arranged on the yarn collecting guider rack 1301 through bearings; the two yarn collector shafts 1303 are arranged in parallel. The yarns are distributed from the yarn feeding part of the drying box to the yarn collecting guide 8 through the flow divider, are sent to the yarn collecting wheel 1302 through gullies on the surface of each flow divider, are wound repeatedly by the sand thread, are finally collected and wound to the yarn collecting wheel 1302, and the dyeing and sizing process of the yarns is completed.

The specific process for yarn dyeing and sizing of the invention is as follows: dye liquor concentration distribution and heating are completed in a dye liquor distribution heating cylinder 1, yarn is installed in a yarn feeding device 2, yarn ends in the yarn feeding device 2 are guided into a yarn tension pretensioner 3, the yarn is pre-tightened and reversed through the yarn tension pretensioner 3, the yarn ends are guided into an automatic yarn dyeing and arranging mechanism 4, the yarn is rotated through a yarn arranging device lead screw cylinder 102 to complete yarn dyeing and yarn arranging (oxidation reduction reaction), the yarn is guided into an automatic yarn sizing mechanism 6 through a guide mechanism after dyeing is completed, an automatic yarn sizing process is completed, then the yarn enters an automatic yarn drying and arranging mechanism 7, the yarn is rotated through a drying box lead screw 402 to complete a yarn drying process, the yarn ends are guided into a yarn collecting guide 8 through the guide, and finally the yarn is wound outside a cylindrical yarn wheel through guiding.
