Abstract

The invention provides a sewing device for bottom pockets of double-reinforcement cylindrical flexible freight bags. The sewing device comprises a bottom pocket turnup device, a bottom pocket conveying device, an overturn feeding mechanism, a rotary drum mechanism, a sewing assembly and an XY platform. The bottom pocket turnup device is used for turning up four sides of each bottom pocket; the overturn feeding mechanism is used for turning the bottom pockets over and feeding the turned bottom pockets to the sewing assembly; the rotary drum mechanism is used for positioning the bottom pockets, so that the overturn feeding mechanism can turn the bottom pockets over, and the sewing assembly can sew the bottom pockets; the sewing assembly is used for sewing the bottom pockets; the XY platform is used for driving a sewing machine of the sewing assembly to move in an XY plane. By the sewing device, edges of the bottom pockets of the double-reinforcement cylindrical flexible freight bags can be automatically turned, the bottom pockets and the freight bags can be automatically positioned and sewn, and sewn positions of the freight bags and the bottom pockets are flat. The sewing device for the bottom pockets of the double-reinforcement cylindrical flexible freight bags has the advantages the bottom pockets can be automatically fed and sewn, full-automatic integral sewing is performed on the bottom pockets of the freight bags, and the sewing device is good in sewing effect and high in yield and efficiency.

Description

technical field [0001] The invention relates to a sewing device for a bottom bag of a double-striped cylindrical flexible container bag. Background technique [0002] As one of the commonly used packaging bags, the outside is a packaging bag with a double-rib structure, hereinafter referred to as a container bag, and the side of the container bag is integrated. When sewing the container bag, the side edge needs to be fully stretched, and a bottom edge is attached to be sewn to one side of the stretched side edge to form the container bag. For the sewing of the bottom bag of the container bag, the traditional way is to flang the bottom bag to be sewn and position it with the container bag of the curl based on manual labor, and then sew. This method requires high labor intensity, slow speed and low efficiency, which is not conducive to the improvement of production and use benefits. [0003] The above problems should be considered and solved in the sewing process of the b...
