Problems solved by technology

However, the existing bobbin detection technology is only capable of detecting insufficient bobbin thread margin, and immediately shuts down when the bobbin thread margin is insufficient, and sends a corresponding bobbin replacement alarm. It does not have a corresponding set of suitable humanized control. method, which cannot meet the needs of customers in different working conditions

Abstract

The invention provides a sewing machine bobbin thread detection control method, comprising the sequential steps of providing a sewing machine with an electronic control module, an operating panel anda bobbin thread remainder detection mechanism. The electronic control module is at least pre-provided with the warning modes of an instantaneous warning mode that allows instantaneous warning in caseof insufficient bobbin thread remainder, and a delay warning mode that allows set N stitches of sewing to be continued before warning when the bobbin thread remainder is insufficient. The electronic control module selects one warning mode; the sewing machine is started to perform sewing; during sewing, the electronic control module judges whether the bobbin thread remainder on a bobbin is sufficient according to an output signal from a detection sensor; if not, the electronic control module warns on the insufficient bobbin thread remainder according to the selected warning mode. After the insufficient bobbin thread remainder is detected, at least two warning modes are supplied to a user; the limited warning mode of instantaneous shutdown is not provided; the method herein is more humanizedand can meet the requirements of customers under different conditions.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a method for detecting and controlling the bottom thread of a sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the fabric to interweave or sew one or more layers of fabric. When the sewing machine is sewing the fabric, the rotary hook and the needle of the sewing machine cooperate with each other to interweave the bottom thread and the upper thread and sew them on the fabric to form stitches. The upper thread is passed through the needle eye of the machine needle, and the machine needle moves up and down; the rotary hook is composed of a bobbin case and a bobbin, the bobbin is accommodated in the bobbin case, and the bottom thread is wound on the bobbin. The upper thread is generally longer, 3000m-4000m, and the user can observe the amount of upper thread at any time during the sewing p...
