The invention belongs to the technical field of compacting of coiled materials and particularly relates to a traction compacting device of a waterproof coiled material. A bottom plate, a scraping therapy box, a pressing roller, a first guiding roller, a bearing, a chain, a first shaft connecting gear, a cross beam, a second guiding roller, a coiling block, a first gear, a first supporting plate, asecond shaft connecting gear, a motor box, a second supporting plate, a third supporting plate, a second gear, a sweeping
brush, a strip-shaped channel, a speed reducing motor, a stepping motor, a telescopic rotating shaft, a first round rod, a first spring, an intermediate shaft, a second round rod, a positioning pin, a rolling wheel, an auxiliary roller, an arc-shaped plate, a protrusion, a supporting rod, a second spring and a
cam. According to the traction compacting device of the waterproof coiled material, in the process of performing traction compacting of the waterproof coiled material, under mutual cooperation of the scraping therapy box, the sweeping
brush and the speed reducing motor, sand remaining on the surface of the coiled material in the previous work procedure is discharged out of through holes in the side edge of the scraping therapy box through the sweeping
brush, and it is avoided that the coiled material is broken in the compacting process.
