The invention discloses an automatic yarn cutter for textile machinery, and relates to the field of textile machinery. It includes an assembly plate and a spiral steel wire frame one and a spiral steel wire frame two that are fixedly arranged on the upper part of the assembly plate and are relatively distributed. The spiral steel wire frame one and the spiral steel wire frame are arranged oppositely. There is spinning yarn interspersed between the two steel wire frames, which is used to clamp and limit the spinning yarn. The clamping mechanism is located on the upper part of the assembly plate, and there is also a device for cutting the spinning yarn between the clamping mechanism and the assembly plate. In the yarn cutting mechanism, in the present invention, the driving mechanism drives the sliding rod to move downward. When the round bottom pressing block restricts both ends of the spinning cut, the continuous downward movement of the sliding rod triggers the yarn cutting mechanism through the pushing assembly, allowing the yarn cutting mechanism to be triggered. The cutter cuts the spinning yarn. This cutting method can avoid the ineffective restriction of the spinning yarn, which causes the spinning yarn to follow the pressure of the cutter during the cutting process and cause the spinning yarn to be incompletely cut.
