Description

Spinning tow center oiling device and spinning equipment

Technical Field

The application belongs to the technical field of regenerated polyester fiber production, and particularly relates to a spinning tow center oiling device and spinning equipment.

Background

The process for preparing the regenerated polyester fiber mainly comprises the following steps: vacuum drying, extrusion melting, filtering, high-pressure spinning, circular blowing cooling, drafting, tension heat setting, curling and relaxation heat setting. Wherein, the materials are extruded and melted, and then are spun by high-pressure spinning of a spinning box body, and fiber tows are cooled by a circular blowing device and then sent to the next working procedure through a yarn outlet. With the continuous upgrading of products and the progress of the process, the regenerated high-pressure spinning is developed to the high productivity and high strength directions, namely: increasing the number of orifices and decreasing the orifice diameter (spinning a fiber tow having a greater number of filaments and a smaller fineness of the semifinished product of the fiber). For example, in a spinning box for spinning high-strength 1.2 denier regenerated polyester staple fibers by using waste polyester bottle chips and waste polyester textile leftover materials as raw materials, a spinneret plate is increased from a conventional phi 328 multiplied by 3220 hole to a conventional phi 358 multiplied by 4600 hole, so that the yield is increased and the fineness of a semi-finished product of the fibers is reduced. As the number of orifices increases, the difficulty in cooling the fiber strands ejected from the manifold increases accordingly. If a single circular blow cooling system is used, fiber tows near the middle tend to have inconsistent bonding and cooling points due to reduced wind penetration. If the wind velocity is increased, the external fiber tows are solidified too early and the spinneret temperature is affected. At present, in the spinning process, an oil applying ring is generally adopted to apply oil to the fiber tows, so that the fiber tows can be further cooled while the oil on the oil applying ring is adsorbed to reduce or eliminate the electrostatic effect. The upper oil ring is generally arranged at the oil groove below the guide head, and the oil flows to the upper oil ring after overflowing through the oil groove, but the peripheral side surface of the upper oil ring cannot be in stable contact with the fiber tows, so that uneven oiling of the fiber tows is caused, the quality of the fiber tows is further affected, and the oil is wasted.
