By using technique scheme, arc section defines the maximum turning of melt distribution runner, it is achieved melt is mild Break-in, is not susceptible to blocking and causes runner to impact.

Preferably, described melt enters joint and is laterally provided with two melt outlet, and melt outlet is divided by main melt flow channel Lian Jie there is not diverter module.

By using technique scheme, a melt enters joint two main melt flow channel of supply, a main melt flow Road is formed two melt distribution runners by diverter module again so that the melt being connected with screw extruder enters joint and can supply The work of four spinnerets, volume of production is big, and work efficiency is high.

Preferably, the sidewall of described spinning head installation chamber is fixed with a pair symmetrically arranged guided plate, guided plate head Stretch out spinning head chamber and guided plate head inwall are installed to be provided with the guide margin of inclination.

By using technique scheme, guided plate facilitates spinneret to put into installation chamber, the guide margin structure profit that it tilts With the centering installing chamber when spinneret is put in the early stage.

Preferably, guided plate is detachably secured to spinning head and installs chamber sidewall.

By using technique scheme, it is convenient for changing the guided plate that deformation occurs.

Preferably, dosing pump module lower end is provided with dagger, and dagger is supported on box bottom.

By using technique scheme, compare traditional hanging structure, after dosing pump module bottom is provided with support column, temperature Degree shape is more preferable, is difficult to rock.

Preferably, described melt enters joint and is made up of upper shell, lower shell, flange, and lower shell is fixed on casing, method Orchid is connected between upper shell and lower shell and by both.

By using technique scheme, upper shell can disassemble easily, the internal blocking of cleaning joint.

Preferably, described upper shell and lower shell are surrounded by inside and outside two-layer steel bushing respectively, and between two-layer steel bushing, hollow is formed Heat-insulation layer.

By using technique scheme, melt is difficult to distribute to the external world heat when supplying melt and entering joint.

In sum, compared with prior art, this utility model has the advantage that melt canal more reasonable structure, subtracts Few melt flows dead angle；One dosing pump four spinneret of supply, production efficiency is higher；Spinneret is installed more convenient；Melt enters Enter joint good heat insulating.
