Problems solved by technology

However, in the practical application of winding, the O-shaped elastic ring is prone to aging or damage as a consumable, and the aging or damage of the O-shaped elastic ring will weaken the tightening effect and even make the tightening parts invalid. Therefore, the staff need to Frequent maintenance of the winding device such as replacing the O-shaped elastic ring is time-consuming and laborious, and it is not conducive to the continuous production of chemical fiber filaments

Abstract

The invention discloses a bobbin tensioning shaft and a chemical fiber filament winding device. The bobbin tensioning shaft comprises a shaft barrel. The shaft barrel is internally provided with a first ejector bar with the axial freedom of the shaft barrel. One or more bobbin tensioning assemblies are arranged on the first ejector bar. The at least one bobbin tensioning assembly comprises a frustum sliding block and an expansion block which are matched with each other. The outer diameter edge of the frustum sliding block is in axial linear variation along the shaft barrel. The frustum sliding block is driven by the first ejector bar to move axially along the shaft barrel to make the expansion block move radially relative to the shaft barrel, and thus the concave-convex degree of the expansion block relative to the shaft barrel is changed. The chemical fiber filament winding device comprises at least one bobbin tensioning shaft. The bobbin tensioning shaft is easy and convenient to control, efficient, stable and long in maintenance period, and the continuous production of chemical fiber filaments is facilitated.

Description

technical field [0001] The present application relates to the technical field of chemical fiber filament winding, in particular to a bobbin tensioning shaft and a chemical fiber filament winding device. Background technique [0002] Chemical fibers such as spandex fibers are continuous filaments (referred to as chemical fiber filaments). The filament is wound up by a winding device during the spinning process. The winding device includes a winding shaft that can be installed with a bobbin. The winding shaft drives the bobbin to rotate and other controls to wind the filament onto the bobbin. When the filament wound on the bobbin meets the predetermined winding requirements, it can be removed. The winding bobbin on the reel is replaced with an empty bobbin to continue the filament winding. [0003] In order to ensure the normal and stable winding of the filament, it is necessary to ensure that the bobbin in the winding device and the winding shaft on which the bobbin is inst...
