The invention relates to an automatic processing system for textile fabric preparation. The system includes a base, singeing mechanisms, support legs, a first fixing board, a second fixing board, a cross rod, a transition roller and a tank body. The tank body is fixedly mounted on the right end face of the base, the support legs are symmetrically mounted at the left end of the lower end face of the base and the right end of the lower end face of the tank body, the first fixing board and the second fixing board are symmetrically mounted at the left and right two ends of the upper end face of the base, and the singeing mechanisms are arranged between the inner side ends of the middle of the first fixing board and the inner side ends of the upper ends of the second fixing board. According tothe system, an efficient automatic idea is adopted to process flocks on the surface of textile fabric, the double faces of the textile fabric can be subjected to automatic singeing processing, meanwhile through the matching between an electric push rod, a sliding seat and a sliding groove, the function of height adjustment of the roller can be achieved, so that the textile fabric with different tension can be subjected to singeing processing, and the singeing efficiency of the system can be achieved.
