Description

Technical Field

[0002] Currently, the sewing process for T-shirts in the sewing industry is still primarily manual, with limited research into automated sewing. Existing sewing equipment is generally semi-automatic, requiring manual alignment of the threaded collar with the fabric during the sewing process. This places high demands on workers and results in low sewing efficiency. Manual feeding of materials during automatic feeding often results in material deviation, necessitating the use of a correction device to correct the feed direction.

[0003] Chinese patent document with application number 201820188938.4 discloses an automatic correction mechanism, including a fixed plate, an electric actuator, a pneumatic actuator, a movable pull rod and an adjustable pressure roller bracket. The fixed plate is an L-shaped plate. The upper end of the fixed plate is fixedly installed with an adjustable pressure roller bracket and a movable pull rod. The adjustable pressure roller bracket and the movable pull rod are respectively installed on the two side surfaces of the upper end of the fixed plate. The right end of the adjustable pressure roller bracket is fixedly connected to the pressure roller, and the left end is fixedly connected to the electric actuator. A synchronous wheel is sleeved between the left end of the pressure roller and the electric actuator. A pneumatic actuator is also installed on the fixed plate on the left side of the movable pull rod. A correction wheel is installed on the end of the movable pull rod extending out of the fixed plate on the right side. The correction wheel is rotatably connected to the movable pull rod, and a synchronous wheel connected to the electric actuator is sleeved on the correction wheel.

[0004] The automatic deflection-correcting mechanism achieves deflection correction by rotating the deflection-correcting wheel to move the material.
