Sewing machine and mechanism for reducing vibration of sewing machine

Abstract

The invention relates to a mechanism for reducing vibration of a sewing machine. An upper rotating shaft of the sewing machine is in transmission connection with a sewing needle connection rod capable of realizing up-and-down reciprocating motion; a lower rotating shaft of the sewing machine is in transmission connection with a bending needle connection rod capable of realizing left-and-right reciprocating motion through a transmission shaft; inertia force in a vertical direction is applied to the sewing machine by the up-and-down reciprocating motion of the sewing needle connection rod; inertia force in a left-right direction is applied to the sewing machine by the left-and-right reciprocating motion of the bending needle connection rod. The upper rotating shaft is connected with an upper shaft balancing block, the lower rotating shaft is connected with a lower shaft balancing block, and the transmission shaft is connected with an additional balancing block, so that the upper shaft balancing block, the lower shaft balancing block and the additional balancing block can offset the inertia force generated by rotating parts on the upper rotating shaft, the lower rotating shaft and the transmission shaft when the sewing machine operates; the vibration of the sewing machine can be reduced; the noise generated by the sewing machine can be reduced; the mechanical abrasion of the sewing machine can be reduced; the service life of the sewing machine can be prolonged; the working environment of operators can be improved.

Description

technical field [0001] The invention relates to a sewing machine and a mechanism for reducing the vibration of the sewing machine, in particular to an industrial sewing machine and a mechanism for reducing the vibration of the sewing machine. Background technique [0002] Sewing machines are widely used in garment production, cloth art, packaging and other processing occasions. With the development of industry, the production efficiency of sewing machines is getting higher and higher, and the sewing speed of sewing machines is also getting higher and higher. There are a large number of moving parts in industrial sewing machines, and the quality of each moving part is concentrated to its own center of gravity. The position and the center of gravity are also often called the center of mass. When the machine is running at high speed, the position of the above-mentioned particle in space changes periodically, and due to the high speed of movement, it will inevitably generate a l...

AI Technical Summary

Problems solved by technology

This kind of vibration will not only produce harsh noise, but also aggravate the wear and tear of the kinematic pair of moving parts, affect the working accuracy and reliability of the machine, and cause damage to the physical and mental health of operators.
