Description

Technical Field

[0001] This utility model relates to the field of zipper tape production technology, specifically a zipper tape feeding mechanism. Background Technology

[0002] Zipper tape pre-expansion is a key process in zipper forming. It uses a pre-expansion mold to stretch the zipper teeth and fabric tape to a preset distance, providing precise positioning for subsequent zipper assembly, sewing, or cutting. This directly affects the smoothness of meshing and the structural strength of the finished zipper. During dynamic feeding, the pre-expansion machine must maintain stable tension of the zipper tape, accurate longitudinal alignment of the zipper teeth, and no wrinkles on the fabric edge. Otherwise, it may lead to deformation of the zipper teeth, jamming of the pre-expansion mold, or misalignment during subsequent zipper assembly.

[0003] When the existing feeding mechanism is in use, the static limiting method cannot adapt to the dynamic posture changes of the chain teeth, which makes the front chain teeth easily deviate from the mold guide groove. The coordination between pressing and conveying is poor. A single / offset pressing point causes the middle belt to loosen and wrinkle. The overall pressing also hinders the entry of the mold cavity, requiring additional processes or extending the production time.

[0004] Therefore, a zipper belt feeding mechanism is needed to improve the above problems. Utility Model Content
