The invention relates to the field of hot melt adhesive production equipment, in particular to a hot melt adhesive producing system with an automatic partitioning function. The hot melt adhesive producing system with the automatic partitioning function comprises a machine body and an operation cavity arranged in the machine body. A rotating frame is rationally arranged in the operation cavity. Rotating racks are arranged in the rotating frame in a left-right symmetry manner and vertically run through the rotating frame. Cooling cavities surrounding the rotating racks are arranged in the end walls of the rotating racks. The hot melt adhesive producing system with the automatic partitioning function can achieve automatic extrusion formation of hot melt adhesive; the rotating frame is rotationally arranged in the equipment, and by means of the rotation shear force of the rotating frame, equal-length cutting is conducted on the hot melt adhesive; a water cooling device used for cooling thehot melt adhesive is arranged in the equipment, so that formation of the hot melt adhesive is accelerated; an ejector device arranged in the equipment and a discharging device can discharge formed hot melt adhesive out of the equipment, production efficiency of the hot melt adhesive is improved, and therefore production, use and popularization are convenient.
