Embodiment Construction

[0025] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] refer to figure 1 . A yarn tensioner for a nylon zipper sewing machine, comprising a yarn inlet wheel 2, a yarn outlet wheel 5, and a tension control assembly 9. The tension control assembly includes a mounting seat 16, and a front tension wheel 3 arranged on the mounting seat 16 And the back tension wheel 4 that is located on the side of the front tension wheel 3, the yarn feed wheel 2, the back tension wheel 4, the front tension wheel 3 and the yarn output wheel 5 are respectively arranged laterally at intervals. On the mounting seat 16, the rotation direction of the front tension wheel 3 and the rear tension wheel 4 is that the yarn inlet wheel 2 rotates to the direction of the yarn output wheel 5, and the front tension wheel 3 and the rear tension wheel A yarn body 1 is wound at intervals on the wheel 4, and the winding method is determined b...

Abstract

The invention relates to a yarn tensioner of a nylon zipper sewing machine. The yarn tensioner of the nylon zipper sewing machine comprises a yarn feeding wheel, a yarn discharging wheel and a tension control assembly, wherein the tension control assembly comprises a mounting seat tension wheel and a back tension wheel; the yarn feeding wheel, the back tension wheel and the yarn discharging wheel are separately arranged on a mounting seat transversely in a spaced manner; a yarn body winds the front tension wheel and the back tension wheel in a spaced manner; the yarn body winds the front tension wheel and the back tension wheel by arranging the front tension wheel and the back tension wheel to eliminate jumping of the yarn body; and in conditions that when the number of winding rings of the yarn body on the front tension wheel and the back tension wheel is one, although the yarn body is of a sort of jumping, and when the number of winding rings are two and three, the poor jumping of the yarn body is substantially eliminated, the yarn tension value is stabilized, and meanwhile, the yarn interrupting rate is decreased, and the product quality is further enhanced, so that the production line equipment is more reasonable in automation.

Description

technical field [0001] The invention relates to a yarn device, in particular to a yarn tensioner for a nylon zipper sewing machine. Background technique [0002] The main function of the nylon zipper sewing machine is to sew the nylon cloth belt and the nylon plain chain together. During the sewing process, the bottom thread and the upper thread are required, and the sewing together becomes a zipper semi-finished nylon zipper blank. [0003] As far as the current situation is concerned, the nylon zipper sewing machine cannot achieve the desired effect by using a tensioner. At present, the industry mainly adopts the clip type and the bilateral cross type, and the main problems are as follows: [0004] 1. The clip-type yarn tensioner mainly adjusts the tension through the spring. First, the production process cannot be standardized. The products produced by the same production process between different equipments are very different, and defective products such as zippers often...
