Variable-breadth yarn guide device

The invention belongs to the field of spinning, and particularly relates to a variable-breadth yarn guide device. The variable-breadth yarn guide device comprises a machine frame, a plurality of groups of movable reeds, a plurality of groups of yarn guide rods and pressure sensors; the multiple groups of movable reeds are arranged on one surface of a yarn outlet of the machine frame and are arranged at intervals in the vertical direction; and the multiple groups of yarn guide rods are arranged on the machine frame, each group of yarn guide rods corresponds to each group of movable reeds, each group of yarn guide rods is composed of a plurality of yarn guide rods, and the pressure sensors are arranged at the two ends of each yarn guide rod. According to the variable-breadth yarn guide device, warp yarns on a plurality of creels are integrated in the same breadth, the breadth is variable, the tension of each piece of warp yarns in the weaving process can be measured, and the warp yarns are clearly arranged in t
