Automatic elastic sewing machine

Abstract

The invention discloses an automatic elastic sewing machine, which comprises a feeding device, a pull device, a turnover manipulator device, a feeding guide rail device and a sewing device, wherein the feeding device and the pull device are arranged at two ends of the turnover manipulator device respectively; the turnover manipulator device is connected and fixed with the feeding guide rail device; the feeding device is used for conveying an elastic band; a clamping mechanism of the pull device is used for clamping the end part of the elastic band at a discharge opening; the pull device drives the elastic band to displace and to pass through a first clamp and a second clamp of the turnover manipulator device under auxiliary feeding of the feeding device; the elastic band is cut off through a blanking mechanism; two ends of the elastic band are rotated for fixing; and the feeding guide rail device drives the elastic band to displace to the lower end of a needle head of the sewing device for sewing. According to the automatic elastic sewing machine, through improvement of the turnover manipulator device, the pull device and the feeding guide rail device in control mode and structure, the running stroke is controllable; the automatic degree is relatively good; the operation is convenient; and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of rubber band production equipment, in particular to an automatic rubber band machine. Background technique [0002] The production of elastic rings, the usual production process is to use bundled or rolled elastic bands as raw materials, cut and sewed into loops in sections; this production process is usually done by hand or by a single machine with different functions. Jointly completed, the authorized announcement number is CN103352330B, a Chinese invention patent for a rubber band machine, which discloses a fully automatic rubber band processing equipment that integrates sorting and feeding, fixed-length cutting, splicing and sewing, and can automatically complete the rubber band. The entire production process of making elastic rings from ribbons, but the main operating mechanism of the fully automatic elastic rings is driven by cylinders, which cannot be controlled in the running stroke so that some automatic fu...

[0002] The production of elastic rings, the usual production process is to use bundled or rolled elastic bands as raw materials, cut and sewed into loops in sections; this production process is usually done by hand or by a single machine with different functions. Jointly completed, the authorized announcement number is CN103352330B, a Chinese invention patent for a rubber band machine, which discloses a fully automatic rubber band processing equipment that integrates sorting and feeding, fixed-length cutting, splicing and sewing, and can automatically complete the rubber band. The entire production process of making elastic rings from ribbons, but the main operating mechanism of the fully automatic elastic rings is driven by cylinders, which cannot be controlled in the running stroke so that some automatic functions cannot be realized, and the insufficient design of some components makes the elastic The production adjustment of the belt is inconvenient, and there is potential for further improvement in processing performance and production assembly
