The invention discloses a waterproof coiled material base fabric asphalt impregnation mechanism which comprises a base. The four corners of the lower end of the base are fixedly connected with fixingplates correspondingly, and the lower ends of the fixing plates are fixedly connected with supporting legs. The upper end of the base is fixedly connected with an impregnation box, and a storing plateis fixedly connected to the side wall of the impregnation box. An opening is formed in the side wall of the storing plate, and a first valve is arranged at the opening. Storing grooves are formed inthe two sides of the storing plate correspondingly, racks are slidably connected to the inner walls of the storing grooves correspondingly, and abutting plates are fixedly connected to one ends of theracks. The ends, away from the racks, of the abutting plates are fixedly connected with second springs, the second springs are fixedly connected to the inner walls of the storing grooves, and throughopenings communicating with the storing grooves are formed in the side wall of the impregnation box. The waterproof coiled material base fabric asphalt impregnation mechanism is simple in structure,convenient to operate, quick in operation, compact in structure, high in impregnation capacity and high in product quality, implementation of recycling work is effective, and the using effect is quitegood.
