A new type of yarn feeder
By combining the driving and driven pressure rollers and controlling them with dual servo motors, the slippage problem of traditional yarn feeders when conveying rovings is solved, achieving stable conveying and tension adjustment of single-path yarns and adapting to different yarn conditions.

AI Technical Summary
Technical Problem
Traditional yarn feeders are prone to slippage when conveying thicker or special yarns, and cannot independently control the synchronous conveying of multiple yarns.
Method used
It adopts a combination structure of driving wheel and driven pressure wheel. Through the meshing connection of driving gear and driven gear, the driven pressure wheel and driving wheel rotate in opposite directions to generate clamping force and friction. Combined with dual servo motors and swing arm to control yarn tension, it realizes stable delivery of single-path yarn.
Benefits of technology
It achieves stable yarn feeding, avoids slippage, and can independently control the feeding of a single yarn path, adapting to changes in yarn thickness and material.

Abstract
This utility model relates to the field of yarn feeder technology, and discloses a novel yarn feeder, including a housing, an internal mounting base, and a yarn feeding motor fixed to the top of the mounting base. A drive wheel is fixed to the motor shaft of the yarn feeding motor, and a drive gear is fixed to the inner end of the drive wheel. A driven pressure roller mounting base is fixed below the yarn feeding motor on the mounting base. A swing arm is rotatably connected to the driven pressure roller mounting base, and a pressure roller shaft is fixed to the end of the swing arm. A driven pressure roller is rotatably connected to the pressure roller shaft via a bearing, and a driven gear is fixed to the inner end of the driven pressure roller. The drive gear and the driven gear are meshed. A spring sleeved on the outside of the swing arm connects the driven pressure roller mounting base and the driven gear. A yarn feeder PCB board is located on the right side of the housing, near the mounting base. This utility model achieves stable single-path yarn feeding.
