Abstract

The invention relates to the technical field of sewing machines, in particular to a single-needle and double-needle sewing state switching device and method of a sewing machine, and aims at solving the technical problems that in the prior art, when an operator operates manually, precision is not high, and a higher sewing technology is needed. The single-needle and double-needle sewing state switching method of the sewing machine comprises the operation step of judging whether operating parameters of the sewing machine meet a first migration condition or not when the sewing machine is in a double-needle sewing state, and according to the relation between the operating parameters of the sewing machine and the first migration condition, enabling a reset mechanism to control the sewing machineto be automatically switched from the double-needle sewing state to the single-needle sewing state. Due to the fact that electronic control is adopted, the operator does not need to specially pay attention to the moment of single-needle and double-needle switching, so that the sewing precision is higher, and the operator does not need a high sewing technology.

Description

Technical field

[0001] The invention relates to the technical field of sewing machines, in particular to a device and method for switching between single and double needle sewing states 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 sewing material to interweave or sew one or more layers of sewing materials. It can be roughly divided into household sewing machines and industrial sewing machines. At present, when the sewing machine is in the single-needle sewing state and the double-needle sewing state, the operator needs to switch manually. Therefore, there is a problem that the control accuracy at the time of the single- and double-needle sewing state conversion is not high, and the operator needs to pay more attention The moment when the sewing state between single and double needles is switched, which puts forward higher requirements on the sewing technology of the operator.Summary...
