Suspension rotating shuttle for thread hooking

Abstract

The invention provides a thread hooking suspension rotating shuttle, and particularly relates to the technical field of sewing machine manufacturing. The device is provided with a motor, a rotating shuttle fixing seat and a suspension shuttle peg, a positioning device and a slide wire gap are arranged between the suspension shuttle peg and the rotating shuttle fixing seat, the rotating shuttle fixing seat is connected with a positioning connecting rod, the front part of the rotating shuttle fixing seat is provided with an anti-slip baffle plate, and a hollow main shaft of the motor is provided with a movable connection part with the positioning connecting rod. And a hollow main shaft of the motor is connected with a crochet needle. The thread hooking suspension rotating shuttle has the advantages that lubricating oil is not needed, contact and abrasion are avoided, the service life is long, a complex change gear set does not need to be matched, the performance of the whole sewing machine is improved, the manufacturing cost of the sewing machine is reduced, and the thread hooking suspension rotating shuttle has the advantages that the design and manufacturing thinking of a traditional sewing machine is subverted; and the popularization value is high.

Description

technical field [0001] The application proposes a thread-hooking suspension hook. The hook-line suspension hook of this program is applied to household sewing machines, industrial lockstitch sewing machines, thick material machines, embroidery machines, roller carts and other sewing equipment that use the hook. Sewing machine manufacturing technology field. Background technique [0002] As a sewing machine for cloth, the sewing machine has a history of more than two hundred years of development. It has made a significant contribution to the development of the clothing industry in human society and promoted the development of human civilization. Throughout the history of the development of sewing machine technology, the rotary hook still follows the original scheme, and the technical principles implemented remain the same. As a key component of sewing equipment, the rotary hook has high requirements for production and manufacturing, and the production cost is also high. In a...

AI Technical Summary

Problems solved by technology

As a key component of sewing equipment, the rotary hook has high requirements for manufacturing and high production costs. In addition, the rotary hook is easily damaged during use and has a high failure rate, resulting in a relatively short service life.

When sewing, when the hook is running at high speed, it is necessary to add grease to the hook body and the high-speed rotating part of the shaft. In addition, the high-speed rotating hook needs to be supported by the mechanical transmission system of the sewing machine, which needs to be matched with a complex gear set , which increases the cost of the sewing machine

The rotary hook and its rotating shaft need to be lubricated, causing pollution to the sewing thread and fabric, and reducing the sewing quality; the high-speed operation of the rotary hook restricts the development of intelligent automation, oil-free, and lightweight sewing equipment
