Outer ring-blowing cooling and center oiling device for composite spinning

Abstract

An outer ring-blowing cooling and center oiling device for composite spinning comprises an outer shell, a cold air input pipeline, a cold air flow guide plate, an air distribution air flue, a ring-blowing air flue, a ring-blowing plate, a ring-blowing net, an oiling unit, a moving unit and a circulating oiling unit. A cold air inlet is formed in the lower end of the outer shell, the cold air input pipeline is connected with the cold air inlet, the cold air flow guide plate is horizontally installed above the cold air inlet, the air distribution air flue is arranged below the cold air flow guide plate, the ring-blowing plate is installed in the outer shell, the ring-blowing air flue is formed due to the distance between the ring-blowing plate and the outer shell, a plurality of air distribution holes are formed in the cold air flow guide plate, the ring-blowing net is installed in the ring-blowing plate, and a spun silk falling and cooling channel is arranged in the ring-blowing net; the oiling unit comprises a conical cover, an oiling plate and an oil receiving plate, an oiling lip is arranged on the periphery of the oiling plate, a distance fine tuning mechanism is arranged between the oiling plate and the conical cover, the circulating oiling unit determines oil supply amount by controlling the rotation speed of a variable-frequency oil pump, and the moving unit is pushed and pulled through a pneumatic pushing and pulling device so that the oiling unit can be moved to enter or exit.

Description

technical field [0001] The invention relates to an outer ring blowing cooling and center oiling device for composite spinning, which is a device for cooling and shaping the composite spinning filaments and for spinning oiling at the center of the spinning outlet, and belongs to the technical field of synthetic fiber composite spinning and chemical fiber machinery . Background technique [0002] The cooling process of composite spinning is the forming and setting process of spinning. After the chemical polymer is melted, it is formed into a filament by a spinning device, and the filamentous chemical is cooled and shaped by blowing cold air, and the filamentous chemical that is shaped after blowing cold air becomes a chemical fiber filament. The traditional method of blowing cold air is to use side blowing. The most prominent disadvantage of this method is that the energy consumption is particularly large, and the cooling wind is not uniform enough, which increases the produ...

AI Technical Summary

Problems solved by technology

The wheel is a circular plane body, the oil is evenly distributed on the wheel surface, and the yarn is oiled on the wheel surface in the form of a bundle, and the part of the filament in the tow that directly contacts the wheel surface is fully oiled, and the silk that does not directly contact the wheel surface The oiling of the strips cannot be guaranteed, the direct consequence is that the oiling cannot be uniform and sufficient, and the extension consequence is that the quality of spinning cannot be guaranteed
