Yarn guide device for TSB-36 doubling machine

The utility model discloses a yarn guide device, particularly relates to a yarn guide device for a TSB-36 doubling machine, and aims to provide a yarn guide device which is simple in structure and whereby yarn tension is uniformized, work intensity is reduced, spinning cost is reduced and production quality and efficiency is improved. The yarn guide device comprises a base, an L-shaped fixing block, an arc retaining block and a fixing copper sheet. The yarn guide device is mounted on a yarn guide plate in the middle of the yarn guide plate which is arranged between a tensioner and a balloon guide ring, so that the distance between the tensioner and the balloon guide ring is shortened, balloon radius of a yarn formed during re-doubling is limited, a balloon is reduced, and the fact that the yarn swings out of the tensioner is avoided; meanwhile, the yarn passes a guide porcelain eyelet formed by the base, the L-shaped fixing block and the retaining block according to the specific positional relation, and unifo
