The invention discloses an automatic gluing system for bulletproof non-weft cloth. The automatic gluing system comprises a mounting frame, a filter screen, a suction head, a hook, a spring buckle, a liquid level controller, a gluing assembly, a stirring assembly, a filtering assembly, a first return pipe, a second return pipe and an automatic control valve, wherein a glue tank is welded on the outer wall of the top end of the mounting frame; gluing rollers are symmetrically arranged in the middles of the inner walls of the two sides of the glue tank; first supports are rotationally arranged onthe inner walls of the two sides, positioned above the gluing rollers, of the glue tank; and springs are welded on the outer walls of one sides of the middles of the first supports. According to theautomatic gluing system, all control systems are pneumatically controlled, so that the hidden danger of safety accidents in the use process of oily volatile solvents is avoided; glue liquid is alwaysin a flowing state in the glue tank and a glue pot, so that the phenomenon that the glue liquid is exposed in the air and is condensed is avoided, and the uniformity of gluing of the production clothsurface is guaranteed; and the automatic gluing system of the glue pot guarantees timely supplement of the glue liquid after the use of the glue liquid is reduced, so that the labor intensity of workers is reduced, and the working efficiency is improved.
