Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a napping mechanism and a chemical fiber double twisting machine thereof. Background Art

[0002] The brushed mechanism chemical fiber two-for-one twisting machine combines the technology of modern textile machinery to achieve efficient two-for-one twisting of chemical fiber. The machine has the characteristics of low power consumption, convenient operation and high reliability. It is widely used in the textile industry, especially for production scenarios that need to improve yarn strength and quality.

[0003] The prior art discloses a machine for twisting and sanding chemical fiber filaments (CN115045016B), which is provided with a sanding component. The trajectory formed by the chemical fiber filaments during the twisting process is used to automatically scrape the sanding cavity of the sanding cylinder, thereby combining the twisting and sanding into one. The sanding shell is suspended under the upper horizontal plate and is in a dynamic balance state. The swinging sanding shell can in turn hit the chemical fiber filaments to improve the sanding effect.

[0004] In the prior art, the turntable drives the installation shaft to rotate while the bobbin releases the chemical fiber filaments. During the release process, the bobbin rotates, and the chemical fiber filaments are passed directly out from the side hole above the ceramic ring and are sanded. When the chemical fiber filaments are released to the lower half of the bobbin, the chemical fiber filaments are in a long straight line from the bobbin to the top of the ceramic ring, which may get stuck and break. In addition, during the entire transmission process of the chemical fiber filaments, the tension of the chemical fiber filaments is not controlled, so the chemical fiber filaments are easy to break. During the sanding process, the position of the chemical fiber filaments is also easy to shift, and the sanding is not accurate.
