Cover Automatic Sewing Machine

Abstract

The invention relates to the technical field of sewing machines, in particular to an automatic cover sewing machine. It adopts upper roller feeding structure and auxiliary edge device, which can realize automatic sewing. The technical solution of the present invention includes a machine head and a bottom plate. One side of the machine head is provided with a mounting plate, and two clamping seats are connected to the mounting plate. The thread clamping seats are connected to the motor mounting seat through a steel pipe. A motor is connected to the motor mounting base, and a main synchronous pulley is connected to the motor. The main synchronous pulley is connected to a lower synchronous pulley assembly through a synchronous belt, and the lower synchronous pulley assembly is arranged on the main connecting shaft. The main connecting shaft is connected with the first feeding part, the second feeding part and the third feeding part, the first feeding part and the third feeding part are located on the right side of the motor mounting plate, and the second feeding part is located on the left side of the motor mounting plate Side, the left side of the needle plate of the bottom plate is provided with an auxiliary feeding component, and the right side is provided with an edge detection component.

[0002] Notebooks, certificates, certificates and other covers are referred to as covers. In recent years, in order to pursue beautiful appearance, merchants have used hard or soft leather materials for the outer packaging of some products, such as hotel menus, high-end notebooks, certificates, certificates, etc. Demand Ascension has opened up a new development path for the sewing industry. Covers are generally sewn with four-sided single-thread sewing, which requires beautiful stitches, neat distances from the sidelines, uniform corners, and a few stitches overlap at the beginning and end of sewing to avoid threading. The process is single. Ordinary lockstitch sewing machines can satisfy straight-line sewing, but the corners are not easy to control. The current sewing machine needs to manually operate the four corners, and often there is one more stitch or one less turn. The stitch distance from the sideline is not neat, the corners are not uniform, and the labor efficiency is low, and the cost is high. Ordinary lockstitch sewing machines use the feed dog to feed the material, which is easy to scratch the cover and has a high scrap rate.
