Abstract

The invention discloses a dual-motor driven computerized sewing machine. The machine is characterized in that an independent feeding servo motor is directly installed on a feeding rack of a machine body and synchronously coordinates with the positioning signal of a main servo motor driving a main shaft to swing to feed the cloth. The computerized sewing machine designed in the invention has the following beneficial effects: 1. the independent feeding servo motor is directly installed on the feeding rack of the computerized sewing machine and synchronously coordinates with the positioning signal of the main servo motor driving the main shaft to swing to feed the cloth; the mechanical parts and electromagnet assemblies such as mechanical connecting rods, swing cams and the like are removed;and the transmission noises and vibration are reduced; 2. automatic backstitching and manual backstitching can be synchronously carried out via the turnover operating position set by the main motor and the backstitching speed is simultaneously increased; 3. the problems of oilless lubrication and pollution can be solved; the sewing machine assembly technology and manufacturing cost and processes can be simultaneously reduced; and volume production is easy to realize; and 4. a display can be installed in front of the machine body on the right so as to be convenient for operation and observation.

Description

[0001] technical field [0002] The invention relates to a computerized lockstitch sewing machine, in particular to a dual-motor driven computerized lockstitch sewing machine, which belongs to the field of industrial lockstitch sewing machines. Background technique [0003] Traditional industrial lockstitch sewing machines are all driven by a motor for piercing, cloth feeding, reverse sewing, etc. The cloth feeding work is driven by the rotation of the main shaft to drive two sets of eccentric cams, which are driven by the connecting rod to reverse the stitching turning mechanism, and then driven The cloth feeding swing mechanism cooperates with the sinking and floating mechanism to complete the cloth feeding work. This requires a large number of precision mechanical parts and electromagnet components and professional technical personnel to complete, and noise and vibration affect the staff and the environment. Contents of the invention [0004] The purpose of the pre...
