Abstract

The invention relates to the technical field of sewing machinery and equipment, in particular to a presser foot mechanism of a computer pattern sewing machine. The presser foot mechanism of the computer pattern sewing machine is arranged on a machine head. The presser foot mechanism is characterized by comprising a stepper motor, a transmission structure, a presser foot rod guide shaft, a spring, a pressing rod, a pressing rod guide frame and a presser foot, the upper end of the presser foot rod guide shaft is provided with a pressure-regulating screw and a pressure-regulating nut, the stepper motor is connected with the pressing rod through the transmission mechanism, the lower end of the presser foot rod guide shaft is connected with the upper end of the pressing rod, the presser foot rod guide shaft is sleeved with the spring, the lower end of the pressing rod is connected with the presser foot, and the lower portion of the pressing rod is provided with a presser rod lower sleeve. The presser foot mechanism of the computer pattern sewing machine is simple in structure and convenient to operate.

Description

Technical field [0001] The invention relates to the technical field of sewing machinery and equipment, in particular to a presser foot mechanism of a computer pattern car. Background technique [0002] At present, the presser foot mechanism of the existing computer pattern car on the market generally has the problem of "up and down the stairs". When the material to be sewn suddenly thickens or becomes thinner, it is easy to cause jams, skipped stitches, etc. The lifting amount of the foot mechanism cannot be automatically adjusted with the thickness of the material, so there are certain limitations. Summary of the invention [0003] The invention provides a presser foot mechanism of a computer pattern car with simple structure and convenient operation. [0004] The present invention is realized through the following technical solutions: [0005] A presser foot mechanism of a computer pattern car is arranged on the machine head, and includes a stepping motor, a transmission structure...
