Direct-driving single needle industrial sewing machine control system

Abstract

The invention discloses a direct-drive control system of a single-needle industrial flat bed sewing machine. The system consists of a processor, an operation board, a communication circuit, a motor drive circuit, an electromagnetic valve drive circuit, a footrest detecting circuit, a position detecting circuit, a motor, an over-current protection circuit, a voltage detecting circuit, a current detecting circuit, a switch power, a rectification circuit and a footrest speed regulator; the design of a hardware circuit and software of the system is modularized; thread stop motion is relatively rapid, accurate and free of lagged thread; the overlap ratio of stitch is high, stitching is accurately numbered and sewing process is relatively stable; a human and machine operation interface is more humanized and exercisable, and Chinese characters are also displayed, thereby overcoming the disadvantages of the traditional human and machine interfaces that only English and numerical information is available.

Description

technical field [0001] The invention relates to a control system of an industrial lockstitch sewing machine, in particular to a control system of a direct-drive single-needle industrial computerized lockstitch sewing machine. Background technique [0002] 1. Research status at home and abroad [0003] With the development of market demand, users have higher and higher requirements for sewing equipment, which directly promotes the rapid innovation of sewing equipment control system. At present, the research on the sewing machine control system at home and abroad presents the following situation: [0004] 1) Since the direct-drive computerized lockstitch sewing machine uses a built-in motor to directly drive the sewing machine, it has the advantages of quick and convenient installation, easy maintenance, enlarged operating space, more comfortable sewing, small size of the whole machine, and convenient transportation. Once the computer lockstitch sewing machine appeared on th...

Problems solved by technology

[0007] 4) At present, research on the control system of direct-drive computerized sewing machines has not yet been carried out in China, and the research hotspots are still concentrated on the control system of ordinary lockstitch machines

Although China's sewing machine industry has made great progress in recent years, manufacturers have invested relatively heavily in R&D and technology, and the production of sewing machines has gradually shifted to China, but compared with their counterparts in Japan, there is still a gap in R&D and technology. very big

[0009] 2. The shortcomings of the current computerized sewing machine control system

[0013] Judging from the product development of the entire sewing machine control system in China, the products are mainly imitated foreign products, lacking independent innovation
