Problems solved by technology
[0004] The above-mentioned presser foot pressure adjustment device is manually adjusted, which is inconvenient to operate; especially in the process of continuously increasing the presser foot pressure adjustment process, it is necessary to increase the depth of the pressure adjustment screw screwed into the casing, which also increases the manual operation. The force applied to the pressure regulating screw greatly increases the labor intensity for manual pressure regulation

The invention provides an automatic presser foot pressure regulating device, which includes a pressure rod, a presser foot installed at the lower end of the pressure rod, a pressure regulating drive source, and a pressure regulating driving rod that can be moved up and down in a sewing machine casing. The driving source is connected with the pressure regulating driving rod, drives the pressure regulating driving rod to move up and down, and the lower end of the pressure regulating driving rod is connected with the upper end of the pressure rod. In this application, the pressure regulating driving source can drive the pressure regulating driving rod to move up and down, and the different outputs of the pressure regulating driving source correspond to the different moving strokes of the pressure regulating driving rod, and the pressure regulating driving rod acts on the presser foot through the pressing rod, thereby realizing the pressing The adjustment of foot pressure, automatic presser foot lift, and height adjustment of presser foot lift are automatic, not manual, so that it can respond quickly and accurately, reduce the labor intensity of workers, and thus greatly improve sewing Excellent user experience and performance, and ultimately improve the quality and sewing efficiency of sewn products.
Description
technical field [0001] The invention relates to an automatic presser foot pressure regulating device. [0002] The present invention also relates to a sewing machine comprising the above-mentioned automatic presser foot pressure adjusting device. Background technique [0003] The sewing machine is equipped with a presser foot pressure adjustment device for adjusting the pressure of the presser foot. At present, the presser foot pressure regulating device mainly includes a presser rod assembly at the lower end for installing the presser foot, a pressure regulating spring sleeved on the pressure rod assembly, a pressure regulating screw arranged at the upper end of the pressure rod assembly, and a pressure regulating nut. The screw rod is screwed into the casing of the sewing machine and locked by the pressure regulating nut, and the pressure of the presser foot is adjusted by screwing the pressure regulating screw rod into different depths of the sewing machine casing; A se...
