Problems solved by technology

However, because the rotation of the bobbin is mainly driven by the friction between the shuttle threads, when the bobbin stops rotating, there will be more bobbin threads on the bobbin winding post, resulting in waste of the bobbin threads and the loss of the bottom thread. The remaining amou

Abstract

The invention provides a shuttle peg, a rotary shuttle having same, a sewing machine, and a shuttle line balance detection device and method; the shuttle peg comprises a wrapping post, flanges, a shuttle peg hole axially penetrating the wrapping post and the flanges, and a line winding duct formed between the wrapping post and the flanges; the outer periphery of the wrapping post is provided with a radially protruding isolation board; the isolation board is adjacent to one of the two flanges, and splits the line winding duct into a start winding portion and a main winding portion respectively arranged on two sides of the isolation board; the width of the start winding portion is smaller than that of the main winding portion in the axial direction of the shuttle peg; the shuttle line balance detection device comprises the rotary shuttle having said shuttle peg, a shuttle peg detection unit used for detecting the shuttle peg angular velocity [omega] or the rotation turns M, and a sewing machine electric control module; the shuttle peg detection unit output end is connected with the electric control module. The method and device can improve the sewing machine shuttle line balance detection reliability and sensitivity, and can prevent too many shuttle lines from being left.

Description

technical field [0001] The invention relates to the field of garment sewing equipment. [0002] The invention relates in particular to a bobbin. [0003] The present invention also particularly relates to a rotary hook equipped with the above-mentioned bobbin core. [0004] The present invention also particularly relates to a bobbin thread residual detection device and method installed with the above-mentioned bobbin core.
