Problems solved by technology

The feeding mechanism of the traditional sewing machine is purely mechanical, and the thickness of the sewing material that can be sewed has been determined at the beginning of the design, and the sewing thickness can only be within the maximum thickness that can be sewed. For example, a thin material sewing machine cannot sew thicker sewing materials. , so that its scope of application is limited

Embodiment Construction

[0020] Describe the present invention below in conjunction with specific embodiment:

[0021] The method for controlling the electronic pattern machine in this embodiment to adapt to sewing materials of different thicknesses adopts the following steps:

[0022] Step 1: Establish the displacement formula of the needle bar of the electronic pattern machine:

[0023] The task of the needle bar mechanism is to guide the upper thread through the sewing material and form a thread loop in preparation for the interlocking of the sutures. The main shaft and the needle bar are connected together by a double-crank thread take-up crank and a connecting rod. The main parameters of this mechanism are the crank radius R and the connecting rod length L, and λ=R / L. In the needle bar mechanism, the longer the length of the connecting rod, the smaller the λ value, and the closer the motion of the needle bar is to simple harmonic motion, the acceleration changes most smoothly, and the inertia ge...

Abstract

The invention provides a method for controlling an electro-pattern-sewing machine to be adaptive to sewing of sewing materials of different thicknesses. Firstly, a needle bar mechanism of the electro-pattern-sewing machine is analyzed, and a displacement formula of the needle bar mechanism of the electro-pattern-sewing machine is set up; secondly, according to the inherent parameters of the electro-pattern-sewing machine when the corresponding sewing material thickness is 0, the actual material feeding starting angle and ending angle for sewing the sewing materials of different thicknesses are obtained, and the actual rotation speed of a main shaft is determined. Accordingly, the electro-pattern-sewing machine can sew sewing materials of different thicknesses.

Description

technical field [0001] The invention relates to the technical field of pattern machine sewing, in particular to a method for controlling an electronic pattern machine to adapt to sewing materials of different thicknesses. Background technique [0002] Electronic pattern machine, as a kind of sophisticated mechatronic intelligent sewing equipment, has been widely used in clothing, shoemaking, luggage and other industries. It can complete the function of sewing complex patterns that cannot be successfully completed by ordinary sewing machines, and greatly reduces the factory's demand for skilled workers. Dependence, so the field of use of pattern machines has a tendency to further expand. The feeding mechanism of the traditional sewing machine is purely mechanical, and the thickness of the sewing material that can be sewed has been determined at the beginning of the design, and the sewing thickness can only be within the maximum thickness that can be sewed. For example, a thin...
