Embodiment Construction

[0067] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0068] It should be noted that when a component is referred to as being "mounted on" another component, it can be directly on the other component or intervening components can also be present. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other c...

Abstract

The invention relates to a presser foot pressure and tooth frame inclination angle synchronous adjusting method based on an overlock machine. The method includes the steps that the thickness of a fabric is detected in real time in the fabric conveying process; according to the thickness of the fabric, the inclination angle of a tooth frame is correspondingly adjusted through a fabric conveying tooth frame adjusting mechanism; the working pressure is calculated according to the thickness of the fabric, and the pressure of a presser foot is adjusted through a presser foot pressure adjusting mechanism. The invention relates to the presser foot pressure and tooth frame inclination angle synchronous adjusting method based on the overlock machine. The method can be matched with fabrics with different thicknesses, so that sewing of the overlock machine is smooth when the fabric is too thick or stuck, and the sewing quality is improved while the phenomena of non-uniform stitches and wrinklingof the fabric are avoided. The flexible manufacturing capacity of the whole machine system is improved, and application prospects are high.

Description

technical field [0001] The invention relates to the technical field of sewing, in particular to a method for synchronously adjusting presser foot pressure and bracket inclination based on an overlock sewing machine. 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 fab...
