Hemming sewing machine with automatic conveying function

Abstract

The invention discloses a hemming sewing machine with an automatic conveying function. The hemming sewing machine comprises a rack, a worktable and a sewing machine head, wherein the workable and the sewing machine head are arranged on the rack. A conveying bottom plate is arranged on the worktable, and a synchronous belt conveying mechanism for linearly moving sewing materials along the conveying bottom plate is arranged above the conveying bottom plate. Two installing supports are fixed to the worktable, each installing support is provided with a universal bearing, each universal bearing is provided with a movable connecting shaft, and the lower ends of the movable connecting shafts are connected with the top of the synchronous belt conveying mechanism. Balance pressing blocks are fixed to the installing supports, and the bottoms of the balance pressing blocks are provided with springs for applying elastic pressure to the top of the synchronous belt conveying mechanism. By adopting the hanging structure of the universal bearings and applying the elastic pressure through the springs, the working posture of the synchronous belt conveying mechanism can be automatically adjusted, installing and adjusting are convenient, conveying of sewing materials of different thicknesses is convenient, and the sewing material hemming and sewing quality is guaranteed.

Description

technical field [0001] The invention relates to a garment sewing device, in particular to a hemming sewing machine with automatic feeding. Background technique [0002] Invention patent name curling sewing machine, patent application number 201510934857.5 discloses a curling sewing machine, including a folding device arranged in front of the needle drop position on the sewing machine base, the folding device folds back the edge of the cloth so that it overlaps up and down and sends out. In front of the folding device, the conveying belt and the cloth presser are arranged facing each other across the feeding path of the cloth. The material presser moves up and down by the operation of the rotating solenoid, which clamps the material together with the conveyor belt, and applies a moving force in the left and right directions to the material. The detection result of the detector is executed. [0003] In this hemming sewing machine, the cloth introduced into the folding device...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the difficulty of adjusting the levelness of the sewing material conveying mechanism during installation, and simultaneously conveying various thicknesses of sewing materials during the working process will affect the levelness of the conveying mechanism, thereby causing displacement of the conveyed sewing material and affecting the sewing quality technical problems, and provide a crimping sewing machine with automatic material feeding, which has the advantage of self-adjusting levelness, improves installation efficiency, and can adapt to the processing requirements of sewing materials of different thicknesses
