Description

Tooth implanting mechanism for double-point tooth zipper

Technical Field

The invention relates to the field of zipper equipment, in particular to a tooth implanting mechanism for a double-point tooth zipper.

Background

The slide fastener is a coupling member for coupling or separating articles by means of the continuously arranged coupling elements, and the existing slide fasteners are widely used for clothes, bags, tents, and the like. Zippers are generally comprised of two fastener strips each having a row of metal or plastic teeth for engaging the edge of an opening (e.g., a garment or bag mouth), with a slider (slider) for pulling the two rows of teeth into an interlocked position to close the opening. The existing zipper takes the zipper teeth with flat and rectangular cross sections as main parts, most of the zipper teeth are provided with the salient points on the single surface, and the zipper teeth are only provided with the single-surface bulges in the process of conveying the zipper teeth to the zipper cloth belt for arrangement, so that the positioning can be accurately and quickly carried out in the transmission process (the positioning is simple and accurate because the salient points on one surface are arranged on the adjacent surface of the other zipper tooth and the convex surface in the tight arrangement process), and the conveying part has a simple structure.

Therefore, the existing feeding mechanism for single-point teeth cannot meet the requirement of double-point teeth, and an additional tooth implanting mechanism is also needed to be matched with the feeding mechanism for double-point teeth for tooth implantation.
