Description

Technical Field

[0001] The utility model relates to the technical field of fiber processing, in particular to a composite fiber chopping device. Background Art

[0002] Composite fiber is a kind of multi-component fiber, in which two or more unmixed polymer fibers exist on the same fiber cross section. The composite fiber manufacturing technology can obtain two-component fiber with the characteristics of two polymers. There are parallel type, skin-core type, island type and other composite fibers, and the fiber cross section is round and special-shaped. The fiber has three-dimensional curling, high fluffiness and coverage, good conductivity, antistatic and flame retardancy. Composite fiber needs to be spun by a composite spinning machine with a special structure. It is mainly used for wool, blankets, wool fabrics, warm flocking fillings, silk fabrics, non-woven fabrics, medical and sanitary products and special work clothes.

[0003] When the number of fibers to be cut increases, resulting in an increase in thickness, the guiding mechanism in the existing composite fiber chopping device cannot be adjusted and guided in a targeted manner to guide the fiber movement, and the fibers are easily confused during cutting, causing the device to be blocked, thereby reducing the fiber cutting efficiency. Moreover, after the device is shut down after cutting is completed, the fiber dust and impurities generated by the cutting cannot be collected, which has an adverse effect on the working environment and personnel, and endangers human health.
