Problems solved by technology

[0002] Sewing machines are mainly used for fabric sewing of textiles. In traditional sewing machines, the process of adjusting the height of the presser foot and the stitch distance is often two separate adjustment processes, and there are often two independent driving devices to adjust the height of the presser foot and the stitch distance. , making the driving device installed inside the sewing machine complicated, resulting in high production costs and inconvenient maintenance and repair of the sewing machine

Abstract

The invention relates to a combined adjustment method for adjusting stitch length of a sewing machine and height of a presser foot. The sewing machine comprises a controller, a power source, an electronic control element and a driving crank. The electronic control element and the power source are electrically connected with the controller; the driving crank is connected to the power source and isselectively connected with a stitch length adjustment or a presser foot lift. The combined adjustment method comprises allowing the controller to control the electronic control element to operate; allowing the electronic control element to drive the driving crank to selectively connect to the stitch adjustment or the presser foot lift, thereby adjusting the stitch length of the sewing machine or the height of the presser foot. The combined adjustment method allows the stitch length of or the height of the presser foot to be adjusted through one power source; therefore, production cost can be reduced, and it is convenient to maintain the sewing machine.

Description

technical field [0001] The invention relates to the technical field of sewing, in particular to a compound adjustment method. Background technique [0002] Sewing machines are mainly used for fabric sewing of textiles. In traditional sewing machines, the process of adjusting the height of the presser foot and the stitch distance is often two separate adjustment processes, and there are often two independent driving devices to adjust the height of the presser foot and the stitch distance. , so that the driving device installed inside the sewing machine is complicated, resulting in the problems of high production cost and inconvenient maintenance and repair of the sewing machine. Contents of the invention [0003] Based on this, in order to solve the above problems, it is necessary to provide an improved compound adjustment method to achieve the purpose of separately adjusting the corresponding needle distance or presser foot height by one power source. [0004] A composite...
