Abstract

The invention discloses a feed tension stabilizing device for a central line of a zipper. The feed tension stabilizing device comprises a bracket, at least one transverse H-shaped barrel firmly arranged on the bracket, a line arranging mechanism and a drive mechanism, the line arranging mechanism is arranged above the transverse H-shaped barrel and capable of rotating relative to the transverse H-shaped barrel, a tension regulating mechanism is correspondingly arranged at one side of the line winding position of each transverse H-shaped barrel, the tension regulating mechanism comprises a guide rod, a compression spring arranged on the guide rod in a sleeve mode, and a regulating slide block propped against the downside of the compression spring, the regulating slide block is opened with a longitudinal line hole, and the central line is pulled out through the transverse H-shaped barrel, passes through the line hole from the bottom to top, and is dragged by the line arranging mechanism. The feed tension stabilizing device can guarantee that the regulating slide block power is balanced when dragging the central line, the central line tension is kept in a constant state as far as possible, and accordingly the irregular winding due to inconsistent tension is avoided, the braid product difference is reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to a device for adjusting or controlling the tension in filamentary materials, in particular to a device for feeding constant tension on the central line of a zipper. Background technique [0002] The main function of the metal zipper loom or resin zipper loom is to weave the warp, weft, and center line together to form a ribbed belt. It is the center line, so in the weaving process in zipper production, it is often required to be dragged by the motor to pull the center line from its original storage position to the weaving equipment. The above operations often need to take into account the tension during the center line dragging process. Changes, and try to avoid unfavorable conditions that are not conducive to the normal operation of the production line such as the center line entanglement caused by tension changes. [0003] As far as the present is concerned, the various types of threads in the zipper industry mainly use the I...
