Abstract

The invention provides a presser foot height adjusting mechanism for a sewing machine and belongs to the technical field of sewing machine manufacturing. The adjusting mechanism solves the problem that the height of a presser foot of an existing sewing machine is hard to adjust. The sewing machine comprises a machine head and a cylinder, wherein the cylinder is fixed in the machine head, the outer end of a piston rod of the cylinder is hinged to the top of a lifting lever, and the bottom of the lifting lever is connected with a presser foot through a lifting connecting rod, an intermittent lifting rod, a connecting plate and a pressing rod. The adjusting mechanism comprises a stitch length scaleplate and an adjusting shaft, wherein the stitch length scaleplate is located on the outer wall of the machine head and is connected with the lower middle portion of the lifting lever through the adjusting shaft, the lifting lever rotates around the adjusting shaft, and the presser foot can be driven to move up and down by rotating the stitch length scaleplate. The mechanism has the advantage that the height of the presser foot is convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of sewing machine manufacturing, and relates to a sewing machine presser foot, in particular to a sewing machine presser foot height adjustment mechanism. Background technique [0002] During the operation and use of industrial sewing machines, the height of the presser foot needs to be adjusted due to different sewing materials, so that the height of the presser foot is suitable for the thickness of the sewing material. [0003] Existing sewing machines and their presser foot lifting devices, for example, Chinese patent literature discloses a sewing machine frame and its sewing machine presser foot lifting device [patent application number: 201410080457.8; application publication number: CN103981651A], which includes a frame body, The frame body is divided into a beam and a vertical beam. The inside of the beam and the vertical beam is a hollow structure, close to the end of the presser foot assembly, and a...
