Abstract

The invention discloses a bobbin detection device for a sewing machine, belonging to the technical field of sewing machine equipment, which changes the structure of a bobbin winding part to ensure that a hemispherical slide block is not provided with a bobbin or a sewing bottom thread under the condition of using up, the reminding lamp is turned off, so that the user can intuitively judge whether the sewing bottom thread is normally used, thereby avoiding that a user can not sew the sewing material to cause more pinholes when using the sewing machine because the user forgets whether the shuttle peg is installed or not and whether the sewing bottom thread runs out after the last use when using the sewing machine, meanwhile, the characteristic that the thickness is thinner when the amount of the used sewing bottom thread is less is utilized, so that when the amount of the used sewing bottom thread is less, the dial block is used for dialing the dial tone piece to continuously make sound so as to inform a user in advance that the sewing bottom line needs to be supplemented, thereby avoiding the problem that a plurality of pinholes are caused by the fact that the sewing material cannot be sewed after the sewing bottom thread is used up.

Description

Bobbin detection device for sewing machine

Technical Field

The invention relates to the technical field of sewing machine equipment, in particular to a bobbin detection device for a sewing machine.

Background

The sewing machine is a machine which uses one or more sewing threads to form one or more stitches on a sewing material to enable one or more layers of the sewing material to be interwoven or sewn, the sewing machine can be used for sewing fabrics such as cotton, hemp, silk, wool, artificial fiber and the like and products such as leather, plastic, paper and the like, and the sewn stitches are neat, beautiful, flat and firm, the sewing speed is high, and the use is simple and convenient. And derives the artistic forms of hand-push embroidery, computer embroidery, etc.

In the process of using the sewing machine, an upper thread and a bottom thread are required to be used, the bottom thread is generally installed inside the shuttle peg, the protection and thread outgoing effects can be achieved, the bottom thread can be used for sewing the bottom of the sewing material, and the shuttle peg is generally installed below the needle head of the sewing machine.

However, the existing bobbin case cannot correspondingly remind whether the bobbin is installed or not and the thread amount inside the bobbin, so that when the sewing machine is used, a user often forgets whether the bobbin is installed or not when the bobbin is used for the last time, or whether the bottom thread inside the bobbin is used up or not, once the bottom thread is not checked in time, the sewing machine cannot sew the sewing material, a plurality of needle holes can be formed in the sewing material, and the attractiveness of the sewing material is influenced while the quality of the sewing material is reduced.
