Problems solved by technology

This existing selvedge cutting device is temporarily installed on the sewing machine when it is in use. Not only is it bulky, but the overall structure is complex, and it consumes more power because an additional driving motor needs to be installed on the selvedge cutting device.
[0003] In addition, although the existing cloth cutting device is aimed at the cutter control of the cloth edge cutting device, it is also equipped with the erection of the upper blade lifting device, but because it protrudes from the neck position of the car, the user does not need to use the cloth cutting device while sewing. When the side device is installed, it is easy to accidentally touch the device and cause the cutter to drop, thereby causing injury to the user

Description

technical field [0001] The invention relates to a sewing machine, in particular to an automatic cloth cutting device of the sewing machine. Background technique [0002] Generally, after two pieces of fabric are sewn together, there will be redundant and uneven selvedges outside the sutures, which must be trimmed, otherwise it will affect the appearance quality of the clothes, especially the selvedges with special curves such as collars, pockets, and fronts. When pruning, it is even more labor-intensive. In order to solve the problem of trimming the selvage of the sewing machine, there is also a selvedge cutting device, as shown in "the selvage cutting device of the sewing machine" in Taiwan Patent Publication No. 103859 of China. This existing selvedge cutting device is temporarily added to the sewing machine when it is in use. It is not only bulky and has a complex overall structure, but also consumes more power because an additional driving motor needs to be installed on...
