In view of the defect that prior art exists, object of the present invention is a kind of 32 parallel spinning FDY spinning equipments are provided, and compared with 24,32 parallel spinning spinning equipments make single position output improve 30%, and product comprehensive energy consumption declines 20%; The problems such as the tow tension difference that solve that single position tow counts that equipment that increase causes installs that floor space is excessive, lifting head operating difficulties, coiling corner causes is greatly large.

For achieving the above object, the technical solution adopted in the present invention is that 32 parallel spinning FDY spinning equipments comprise filament spinning component, Feng Cang, square tube shape path body and path outlet, described filament spinning component is four spray filament spinning components, surrounded by upper shell and lower house, upper shell and lower house surround four independent sealed cavitys, a spinneret of four each installations of cavity bottom, and fix with lower house; Upper shell top plane is provided with four upper covers, the spinneret orifice concentric of each spinneret of its each upper cover center and lower house, in cavity, set gradually filter screen from top to bottom, cross filter sand, bridge insert, screen pack, distribution plate and spinneret, the parallel arrangement arranged side by side of four independent sealed cavitys that upper shell forms with lower house; Body inside, described square tube shape path is provided with tow buncher, and tow buncher is shiny surface near the inner surface of tow; Body lower end, square tube shape path connects up-coiler filar guide, and tow enters path outlet; Spinning equipment is parallel with winding apparatus installation site, and tow is from spinning equipment to winding apparatus close wind, and without corner, two groups of equipment share an operating surface. Described tow buncher lower end connects up-coiler filar guide, and seal wire and boundling are integrated; Described tow buncher is reversed round bench shaped, up/down perforation, and upside inlet air plenum air-flow flows downward along tow buncher inwall. The filter screen that described upper shell contacts with lower house and with melt, crosses filter sand, bridge insert, and screen pack, distribution plate and spinneret adopt high conduction coefficient material; The edge of screen pack adopts metal hemming edge, without corner angle. Described wind storehouse width 1750mm, is distributed in wide 32 rhizoid bar utilization deadweights and the cooling blast of 1600mm on filament spinning component tow is derived to path outlet, and suction gun catches tow.

Adopt after such scheme, compared with prior art there is following beneficial effect: four spray filament spinning components are surrounded by upper shell and lower house, upper shell and lower house surround four independent sealed cavitys, a spinneret of four each installations of cavity bottom, and fix with lower house, spinning shaft buncher inside is provided with tow buncher, and tow buncher is shiny surface near the inner surface of tow; Body lower end, square tube shape path connects up-coiler filar guide, and tow enters tow draw zone. Suction gun catches rapidly tow, guarantees quick lifting head. By deadweight and cooling blast, tow is derived to path outlet time, minimizing tow lousiness, broken end, to reduce consumption of raw materials, to reduce labor intensity. Buncher surface adopts best bright finish, in path, after installation site and structure optimization experiment, determines design, realizes the function that seal wire and boundling are integrated; Ensure easy lifting head, raw material low consumption. Compared with 24,32 parallel spinning spinning equipments make single position output improve 30%, and product comprehensive energy consumption declines 20%; The problems such as the tow tension difference that solve that single position tow counts that equipment that increase causes installs that floor space is excessive, lifting head operating difficulties, coiling corner causes is greatly large.
