Automatic reel foot machine with double modes of locking and chaining for sewing trouser legs

Abstract

The invention provides a lock-type and chain-type dual-purpose automatic reel machine for sewing trouser legs. The upper shaft, crank, thread take-up, needle bar and needle are driven by a servo motor, and the bevel teeth of the upper shaft drive the vertical shaft. The bevel tooth drives the lower shaft and the shuttle bed installed on the lower shaft cooperates with the needle, and the cloth feeding servo motor is installed behind the machine head, so that the electronically controlled machine can achieve front feeding, needle pitch adjustment, post encryption, encryption function anti-sewing After loosening the thread, the sensor will sense the bone position of the trouser leg when the trouser leg is put in, and direct the machine to run, so as to achieve automatic sewing. By driving the thread pulling shaft, the thread pulling hook seat and the thread pulling hook installed on the thread pulling shaft to move back and forth, it is convenient for the needle to play the function of reverse crossing; thus realizing the conversion from lock stitch to chain stitch; loosen the gear on the The fixed screw of the machine moves the gear connector to connect the front end shaft of the lower shaft to the rear end shaft of the lower shaft. After installing the upper shuttle bed, the conversion from chain stitch to lock stitch can be completed, achieving the function of one machine with two functions.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to a lock-type and chain-type dual-purpose automatic roller foot machine for sewing trouser legs. Background technique [0002] The wheel foot machines of sewing machines in the existing market are all mechanically rotating structures, which cannot be automated. It is necessary to change the gears to adjust the stitch length and disassemble the mechanical adjustment internal structure. According to market demand, sometimes lock stitch is needed, and sometimes chain stitch is needed, and the factory does not want to buy two cars. Only skilled workers can operate, cannot run at high speed, cannot achieve high-efficiency production, poor oil supply, short life of the machine and other problems. Contents of the invention [0003] The object of the present invention is to provide a lock-type and chain-type dual-purpose automatic wheel machine for sewing trouser legs, so as to ...
