A method for quickly adjusting parameters of sewing machine trimming and short thread ends

Abstract

The present invention provides a method for quickly adjusting parameters of sewing machine trimming and short thread ends, comprising the following steps: multiple sewing modes and multiple groups of parameter groups corresponding to each sewing mode are preset in the electric control module of the sewing machine, each group The parameter groups are all matched to the thread trimming mode of the short thread end, and include multiple thread trimming parameters; before sewing, the user selects one of the various sewing modes, and the electronic control module automatically obtains the Each thread trimming parameter in a group of parameter groups corresponding to the sewing mode selected by the user, and the electric control module uses each thread trimming parameter in this group of parameter groups to control the cutting time of the thread trimming mechanism in the sewing machine to perform the thread trimming action . In this application, the sewing mode is associated with the parameter group corresponding to the sewing mode. After the user selects the sewing mode, the electric control module can automatically obtain the parameter group corresponding to the sewing mode, which greatly reduces the user's operation of adjusting the thread trimming parameters. difficulty.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a method for quickly adjusting the parameters of the short thread trimmer of the sewing machine. Background technique [0002] The overlock sewing machine needs to trim the front thread braid formed at the front edge of the sewing material at the beginning of sewing, and the rear thread braid formed at the rear edge of the sewing material after sewing, and some sewing processes have proposed short thread ends for thread trimming. Thread trimming requirements to improve sewing quality and efficiency. Based on this, the Chinese invention patent application with the application number of 201810602769.9 discloses a sewing machine thread trimming control method for overlock sewing machines, which has multiple thread trimming modes, short thread trimming mode and short thread trimming mode among multiple thread trimming modes. The thread trimming compensation mode can realize the trimmi...

Problems solved by technology

[0003] However, since the electric control module of the overlock sewing machine involves more parameters about the thread trimming, the adjustment of the thread trimming parameters is more complicated. It is necessary to adjust multiple thread trimming parameters to achieve the effect of cutting the thread with a short end.

In addition, it is also necessary to adjust the corresponding thread trimming parameters after changing the fabric, otherwise the overlock sewing machine cannot achieve the best thread trimming effect of the short thread end, and the more complicated thread trimming parameter adjustment process will inevitably increase the difficulty of the user's operation
