Description

Technical Field

[0001] This utility model relates to the field of hollow polyester staple fiber crimping technology, and in particular to a stable clamping feeder. Background Technology

[0002] The fiber feeder is one of the important pieces of equipment in hollow polyester staple fiber production. Located between the preheating box and the conveyor, it processes the uniform thickness and tension of the fiber bundles fed from the lead into crimped fibers. The degree of crimp and the number of crimps are important indicators for evaluating the fiber bundles.

[0003] Currently, in existing technology, the feed rollers deliver the filament bundle from the previous stage into the sunflower rollers. The sunflower rollers are a pair of rollers with evenly distributed toothed grooves on their surfaces. During operation, the two sunflower rollers are adjusted to a suitable center distance. When the filament bundle is driven and squeezed by the high-speed rotating sunflower rollers, it forms a certain curling effect.

[0004] The existing technical solutions have the following drawbacks: the existing equipment cannot meet the crimping effect of the filament bundle on a high-volume production line. As the output of the high-capacity production line increases, the total denier of the filament bundle increases. The weight of the two sunflower wheels alone cannot offset the reverse force of the filament bundle on the sunflower wheels, resulting in poor crimping performance and affecting the quality of the filament bundle. Utility Model Content

[0005] The purpose of this invention is to provide a wire feeder with stable clamping to solve the problems existing in the prior art.
