Feeding mechanism of sewing machine

Abstract

The invention relates to a feeding mechanism of a sewing machine. The feeding mechanism comprises a rack, a cloth hanging plate, a driving belt, a limiting rail, ramps, a plurality of thimbles and two driving roller wheels. The two driving roller wheels are rotatably connected with the rack and are connected in a transmission manner through the driving belt. The limiting rail and a high end, and the ramps connected with two ends of the limiting rail, are arranged on a side of a close-loop transmission chain. The plurality of thimbles respectively slide up and down and are elastically arranged on the driving belt. The cloth hanging plate is provided with a spliced eye, and the cloth hanging plate is arranged above the driving belt. Beneficial effects are that the cloth hanging plate which is provided with cloth can be directly driven to do rectilinear motion to feed. Compared with a fell seam machine, the feeding mechanism prevents manual feeding, and positions of cloth hung on cloth hanging needles are relatively fixed, and a water gap can be controlled, and the front end and the rear end of the cloth can be effectively sewed, and a reprocessing program is prevented.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a feeding mechanism of the sewing machine. Background technique [0002] The existing sewing machine includes a sewing machine and a clamping machine. Each model of the sewing machine of the sewing machine corresponds to a specific stitch distance. On the cloth needle, the staff needs to step on the pedal switch to complete the subsequent stitching. This process has high requirements for the proficiency of the staff. Since the cloth hanging needles are very dense, each needle needs to be accurately inserted into the corresponding coil of the fabric. It is difficult for personnel to maintain a high work efficiency. The whole process is completely dependent on manual operation. The labor cost of the factory is high and the production efficiency is low; while the clamping machine requires workers to manually clamp the cloth with a cloth support, and then the worker quickly clamps the cloth.

Problems solved by technology

[0002] Existing sewing machines include disc sewing machines and clamping machines. Each model of the sewing disc of the disc sewing machine corresponds to a specific stitch distance, and the feeding process is Manually thread two layers of fabrics on the hanging needles of the sewing tray one after another, and then need the staff to step on the pedal switch to complete the subsequent sewing. This process has high requirements for the proficiency of the staff, because the hanging needles are very Dense each stitch needs to be accurately inserted into the corresponding coil of the fabric. It is difficult for the staff to maintain a high work efficiency. The whole process is completely dependent on manual operation. The labor cost of the factory is high and the production efficiency is low; Manually clamping the fabric with a cloth support and then quickly dragging the cloth to the discharge direction by the worker will easily cause uneven nozzles, and in this way, when the main needle sews the front and rear ends of the fabric, the cloth support cannot Effectively clamp the corresponding position of the cloth, so the reprocessing procedure of subsequent equipment is required, making the processing cumbersome
