Cutter head device for automatic cutting machine

The utility model belongs to the technical field of cutterheads, and discloses a cutterhead device for an automatic cutting machine, which comprises a cutterhead body, the bottom of the cutterhead body is provided with a plurality of mounting grooves in an annular array, each mounting groove is internally provided with a spherical shell, each spherical shell is internally provided with a rolling ball, and the rolling balls are arranged in the mounting grooves. A notch for exposing the rolling ball is formed in the bottom of the spherical shell, and the bottom of the cutter head body is higher than the bottom of the rolling ball. According to the scheme, the rolling balls are additionally arranged at the bottom of the cutter head body, so that sliding friction is changed into rolling friction when the cutter head body moves and cuts along with the cutting machine, the friction resistance between the cutter head body and cut fabric is reduced, movement is more flexible, and the cutting efficiency is improved. 本
