Monofilament spinning box

The utility model relates to the technical field of chemical fiber machinery, in particular to a monofilament spinning box, comprising a melt distributing pipeline, a metering pump and spinning components, wherein the metering pump comprises an inlet and a plurality of outlets; the outlets of the metering pump are respectively connected with a plurality of spinning components by melt pipes; and the spinning components are single-hole spinning components which produce one monofilament. The monofilament spinning box reforms the traditional spinning box body, each metering pump outlet is connected with one monofilament spinning component by the melt pipe; as the melt entering the monofilament spinning component is metered accurately, the melt passes through the monofilament spinning component with built pressure, thus obtaining monofilament with the accuracy of the metering pump; and if the flow deviation of the metering pump is ignored, the monofilament sprayed by the monofilament spinning component is high-qua
