Description

Technical Field

[0001] The utility model relates to the technical field of fabric traction, in particular to a parallel traction device for special fiber fabrics. Background Art

[0002] Special fiber is a chemical fiber with special physical and chemical structure, properties and uses, or special functions. Most of these fibers are used in industry, national defense, medical treatment, environmental protection and cutting-edge science. When producing special fiber fabrics, they need to be led away from the weaving mouth by a traction device.

[0003] The Chinese patent with the publication number CN202766766U discloses a carbon fiber tubular fabric traction mechanism for a braiding machine, comprising a base, the base being connected to a bracket, the bracket being connected to a worm mechanism through a rotating shaft, and characterized in that a carbon fiber tubular fabric is provided on the worm mechanism, a rubber inner sleeve is provided in the carbon fiber tubular fabric, the upper end of the rubber inner sleeve is provided on the worm mechanism, and the lower end of the rubber inner sleeve is connected to the base.

[0004] Although the above-mentioned traction mechanism pulls the carbon fiber tubular fabric through the rotational movement of the worm mechanism, and supports the shape of the carbon fiber tubular fabric through the inflated rubber inner sleeve to ensure that the carbon fiber tubular fabric does not deform, the bending diameter of the fibers on the outside of the fabric pulled by this method is much larger than that of the fibers on the inside, resulting in inconsistent tension generated by the fibers on both sides of the fabric. The special fibers have poor elasticity and small elongation, which will inevitably damage the strength of the fibers. In addition, it is inconvenient to carry out continuous traction and the efficiency is low. Therefore, we propose a parallel traction device for special fiber fabrics. Utility Model Content
