A feeding and positioning table for a bag sewing machine

Abstract

This utility model discloses a feeding and positioning platform for a bag opening sewing machine, including a feeding mounting seat located below the bag folding mechanism. The feeding mounting seat has a feeding plate, and the feeding mounting seat and the feeding plate have a communicating first mounting groove. A suction positioning plate for positioning the bag lip and bottom lining is slidably installed in the first mounting groove. Below the feeding mounting seat is a first mounting plate fixed to the machine frame. The feeding mounting seat is slidably mounted on the first mounting plate via a guide shaft. The first mounting plate has a lifting cylinder for driving the feeding mounting seat to move up and down. In this utility model, the lifting cylinder drives the feeding mounting seat to move up and down, and the suction positioning plate moves synchronously with the feeding mounting seat. When the pressing and feeding mechanism horizontally moves the cut bag pieces along the worktable between the bag folding mechanism and the feeding and positioning mechanism, the feeding mounting seat moves downwards to avoid conflict with them.

Description

[0002] In garment manufacturing, pocket sewing machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments for carrying small items such as mobile phones and wallets. The conventional approach is to process the pocket opening separately first, and then sew the pocket lip onto the opening to complete the pocket opening. The processing involves cutting, folding, shaping, and sewing the pocket opening area of ​​the garment. Cutting involves making a "Y"-shaped slit at both ends of the pocket opening. Folding involves folding the cut pocket opening inward to form a folded edge. Shaping involves stacking the pocket lip and the folded edge together, and finally sewing them together.

[0003] The material feeding and positioning mechanism is located below the bag folding mechanism, and the bag lip rests on the material feeding and positioning mechanism. The pressing and feeding mechanism horizontally moves the cut bag pieces along the worktable to the space between the bag folding mechanism and the material feeding and positioning mechanism for bag folding. After folding, the bag is stacked on the bag lip on the material feeding and positioning mechanism. During the bag piece transfer and folding process, the material feeding and positioning mechanism needs to avoid obstruction. Summary of the Invention
