Abstract

The invention belongs to the technical field of sewing machines, and particularly relates to a sewing machine presser foot interactive quantity adjusting device, which comprises an eccentric wheel positioned on an upper shaft, a lifting crank positioned on a lifting shaft, and an interactive quantity adjusting mechanism for adjusting the action of a connecting rod assembly, and two ends of an adjusting rocking rod are provided with adjusting heads; the lower part of the adjusting head at one end is supported on the cam surface of a manual adjusting cam, and a pneumatic adjusting presser rod issuspended above the adjusting head at the other end. The invention provides the sewing machine presser foot interactive quantity adjusting device, which allows presser foot interactive quantity to beadjusted manually and be adjusted automatically instantly, so that climb-screwing of a thick material is easily achieved.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and in particular relates to a device for adjusting the interactive amount of a sewing machine presser foot. Background technique [0002] In the actual sewing process of the user, the process requires multi-layer sewing. However, the current sewing machines on the market need to disassemble the parts for re-adjustment for the climbing of this kind of thick material and multi-layer, which is a waste of time and requires professional maintenance personnel. . Contents of the invention [0003] The purpose of the present invention is to provide a sewing machine presser foot interaction volume adjustment device, which can not only manually adjust the presser foot interaction volume, but also automatically and instantaneously adjust the presser foot interaction volume, so as to easily solve the problem of thick material climbing. [0004] The object of the present invention is achieved in t...
