Sewing machine mop device
Technical field
The present invention relates to field of mechanical technique, relate to the mop device of Sewing machines, especially relate to a kind of sewing machine mop device of making the annulus thing.
Background technology
In prior art, normally live sewing by hand when making the annulus thing, make a bit of after, adjust sewing, then continue sewing.This mode not only efficient is lower, and easily appearance is wrinkling simultaneously, the defectives such as sewing dislocation.Therefore, traditional approach is made the needs that annular sewing is difficult to satisfy industrial high efficiency rate, high-quality production.
Along with the segmentation in market and the intensive management of apparel industry, a Sewing machines is often only used in specific operation, makes specific fabric.Sewing machine special is being enhanced productivity, and is user-friendly to, and improves dress ornament and plays a good role qualitatively.For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of feed arrangement [application number: 200810009278] of cylinder-shaped sewing machine, this device is provided with needle plate with the top needle board claw that is configured in the tubular support, at the rear of needle board claw above the tubular support configuration and become a pair of rear roller with front wheel in face of needle board claw, volume hangs on front wheel and rear roller and a part is configured in endless belt on needle plate, with the clutch at intermittence, this intermittently clutch be connected with a side of front wheel or rear roller and link with the rotation of main shaft, give intermittent rotary to this roller; By the endless belt, the cloth that is positioned on needle plate is carried to the cloth direction of feed, be provided with prerotation vane, this prerotation vane has supporting surface, is configured in the both sides of endless belt on rear roller; The part of supporting surface is released to described cloth direction of feed from the endless belt on rear roller.Although this device can be realized the feeding of annulus thing, be difficult to regulate as required, the scope of application is less, and complicated integral structure, and manufacturing cost is high, operates also convenient not.
Summary of the invention
The objective of the invention is for the problems referred to above, provide a kind of and can transport easily the annulus thing, increase work efficiency and sewing quality, and can carry out according to different annulus things the sewing machine mop device of accommodation.
