The invention relates to a melt-blown material strip shaping and cooling device (the melt flow rate is 1200 g/10 min to 2500 g/10 min). Comprising a water tank, one side of the water tank is made into a slope surface (with the gradient of 30-45 degrees), the slope surface is used for bearing melt-blown material strips extruded from a machine head, the high end of the slope surface is located below a die head of the plastic extruding machine, and the low end of the slope surface is located in a water tank. A water inlet is formed in the side wall of the water tank, a water outlet is formed in the top of the water tank, water flows into the water tank through the slope after being discharged from the water outlet, and the flowing water plays a role in lubricating and cooling the drawn material strip. The water tank plays a role in transition supporting, the situation that due to low melt strength, the stretching stress of a melt-blown material strip is too large, and the material strip is broken can be effectiv
