Novel electronic bar tacking machine

Abstract

The invention discloses a novel electronic bar tacking machine, which is composed of a fixed cloth presser foot bar, a needle, a fixed cloth presser foot, a line throwing device, a line throwing device connecting rod, an electromagnet, a spring, a needle bar, a touch screen and the like. A permanent magnet synchronous servo motor is subjected to main shaft driving and connecting; the main shaft driving and connecting is buckled by a cross connector; a digital signal processor (DSP) and UC / 0S-II are control platforms; a stepper motor is driven on the X direction and Y direction; the Y-direction stepper motor drives a length sliding block by a gear to cause an L1 shaft to generate y-direction displacement; and the X-direction stepper motor is characterized in that an arc-shaped gear drives an L2 shaft and a width sliding block to cause the Y shaft to swing in the horizontal direction so as to generate X-direction displacement. A parking position is designed on the upper shaft of a machine head and is formed by dislocating and alternating a crank connected and driven by a front line picking bar and a needle bar to work, a tail line shearing cam and a parking wheel. The novel electronic bar tacking machine has the advantages of simple and scientific structure, few faults and high efficiency, and computer system program control completely replaces manpower.

Description

Technical field: [0001] The invention relates to a tack sewing machine, in particular to a novel electronic tack sewing machine with a new structure. Background technique: [0002] The tacking sewing machine of the prior art is to manually control the cloth presser foot and the thread thrower, and manually fix the cloth and the thread throwing work. When the presser foot is in the sewing process, the cloth is often biased, causing many faults, low efficiency, and walking during the sewing process. If the thread is rough, the user often returns to work, causing trouble to the user, increasing the workload, and even destroying the fabric, resulting in economic losses. Invention content: [0003] Aiming at the deficiencies of the prior art, the present invention provides a novel electronic tacking machine, which consists of a fixed cloth presser foot rod, a needle, a fixed cloth presser foot, a thread thrower, a thread thrower connecting rod, an electromagnet, a spring, a nee...
