Embodiment Construction

[0027] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] figure 1 Shown is one embodiment of the pressing mechanism of the sewing machine of the present invention.

[0029] see figure 1 , the pressing mechanism includes a pressing rod 1 , an external pressure regulating assembly 2 , a lifting guide frame 3 , a connecting ring 4 , and a presser foot assembly 5 . The lifting guide frame 3 is fixed on the pressing rod 1 . The connecting ring 4 is located below the lifting guide frame 3 , it is sheathed on the binder rod 1 , and can slide relative to the binder rod 1 in a certain area. The presser foot assembly 5 is fixed on the lower end of the presser rod 1 .

[0030] The external pressure regulating assembly 2 includes an external pressure regulating rod 6 and a first elastic element 7 . A hole 1 is opened at the bottom of the ou...

Abstract

The invention discloses a sewing machine pressing mechanism, and belongs to the technical field of sewing machines. According to the pressing mechanism, the mode that a first elastic component for providing the downward acting force for a pressing rod is arranged on the upper portion of the pressing rod, and a second elastic component for providing the upward acting force for the pressing rod is arranged on the lower portion of the pressing rod is adopted, the pressure on sewed materials is stable, the buffer effect on the pressing rod is achieved, and the problems that the sewed materials are wrinkled and the service life of a belt is short are solved.

Description

technical field [0001] The invention relates to sewing equipment, in particular to a pressing mechanism of a sewing machine; the invention also relates to a sewing machine provided with the pressing mechanism. Background technique [0002] In the current technology, the pressing mechanism of the sewing machine generally includes a pressing rod, a presser foot assembly pivotally arranged at the lower end of the pressing rod, a lifting guide frame, a connecting ring, and an external pressure regulating assembly composed of an external pressure adjusting screw and a spring. . When this pressing mechanism sews cloth and leather, the sewing material tends to tend due to improper pressure on the sewing material. This tendency phenomenon is more obvious around the sewing stitches, which seriously affects the sewing quality. And the sewing machine that adopts this pressing mechanism, in the process that the belt drives the pulley to rotate, the belt is subjected to alternating load...
