Problems solved by technology

However, the current overlock sewing machine can only process fabrics of a specific thickness. When sewing thick fabrics, the cloth will be layered or the stitches are too dense due to the insufficient mopping force of the cloth feed dog. When sewing thin fabrics, it will Wrinkled stitches due to overfeeding
Overlock sewing machines cannot adapt to fabrics of different thicknesses, which restricts the development and application of overlock sewing machines

Abstract

The invention provides a cloth feeding dog frame adjustment mechanism, which is used to adjust the cloth feeding dog frame in an overlock sewing machine. The cloth feeding dog frame adjustment mechanism includes an adjustment assembly and an operation assembly. The block is embedded in the feed dog rack and can slide relative to the feed dog rack. The eccentric shaft has a concentric section and an eccentric section connected to the concentric section. The eccentric section of the eccentric shaft passes through the adjustment slider and cooperates with the adjustment slider. The operation assembly includes an electric control element, the concentric section of the eccentric shaft is connected to the electric control element, and the electric control element controls the rotation of the eccentric shaft through electric control and drives the adjustment slider to adjust the inclination and height of the feeding dog frame. The present invention also provides an overlock sewing machine using the above-mentioned cloth feeding dog frame adjustment mechanism. The cloth feeding dog frame adjustment mechanism provided by the invention can adjust the inclination angle and the height of the cloth feeding dog frame. The overlock sewing machine using the above-mentioned cloth feed dog adjustment mechanism can improve the sewing quality and the ability of system flexible manufacturing, and has wide application prospects.

Description

technical field [0001] The invention relates to the field of sewing technology, in particular to a cloth feeding dog frame adjustment mechanism and an overlock sewing machine using the device. Background technique [0002] Overlock sewing machine is mainly used for overlock sewing of textiles, and has a wide range of applications in the field of sewing. The feeding process of the overlock sewing machine mainly depends on the reciprocating elliptical motion of the feed dog. The overlock sewing machine continuously lifts and pulls the cloth on the needle plate through the feed dog, so that the cloth to be processed is continuously dragged to the machine. head to complete the entire feeding process. However, the current overlock sewing machine can only process fabrics of a specific thickness. When sewing thick fabrics, the cloth will be layered or the stitches are too dense due to the insufficient mopping force of the cloth feed dog. When sewing thin fabrics, it will Stitch p...
