This utility model discloses an automatic cutting and feeding device for automobile roof production, including a frame and a drive roller. The drive roller is arranged and installed inside the frame, and the device also includes a three-hole fixed plate and a cutting support mechanism. By setting the cutting support mechanism at the frame of the existing patented automatic cutting and feeding device, the main push rod of the cutting support mechanism drives the clamping plate to initially clamp the automobile roof material. At the same time, the auxiliary push rod drives the pressure plate below the guide plate to press down vertically through the corner connecting plate, so that the automobile roof material is tightly pressed against the drive roller and the surface of the T-shaped connecting plate. The sliding cooperation between the T-shaped connecting plate and the groove connecting plate forms a bottom support surface, effectively eliminating the suspended area of ​​the material and avoiding collapse and deformation of the automobile roof material due to insufficient support during cutting. Compared with the traditional clamping structure, the clamping stability is significantly improved.
