Outrigger rotating type independently-driven automatic sewing equipment

Abstract

The invention relates to outrigger rotating type independently-driven automatic sewing equipment. The equipment comprises an upper machine head and a lower machine head which are independently driven respectively, wherein the upper machine head comprises a machine head lifting assembly, a machine head rotating assembly and a machine head assembly, the machine head rotating assembly is fixedly arranged on the machine head lifting assembly, the machine head assembly is fixedly arranged at the lower part of the machine head rotating assembly, and the upper machine head can rise / fall and can also adaptively rotate synchronously with the lower machine head; the lower machine head comprises a bottom line rotating assembly and a bottom shuttling system, the bottom shuttling system is arranged at the upper part of the bottom line rotating assembly, and the bottom line rotating assembly drives the bottom shuttling system to rotate in 360 degrees in any direction; each of the upper and lower machine heads is further provided with a servo-control system, and the servo-control systems control the steering of a bottom line rotating shaft and control the bottom line rotating shaft and machine head rotating shafts to correspond to each other and be in the same rotating speed. The equipment has the advantages that various machining needs can be met, the scope of application is greatly enlarged, and the function is powerful; the stability is high, the failure rate is low, and the maintenance is simple and convenient.

Description

[0001] technical field [0002] The invention relates to the technical field of sewing machines, in particular to an arm-rotating independently driven automatic sewing device. [0003] Background technique [0004] A traditional automatic sewing mechanism generally includes an upper head and a lower head, and the upper head drives the lower head to move synchronously through a transmission mechanism to realize the sewing action. The existing transmission mechanism is complicated, the failure rate is high, and maintenance is troublesome. Moreover, the upper and lower machine heads cannot rotate, and can only sew straight lines. When the needle path changes direction, manual processing is required, and the production efficiency is low. [0005] In the prior art, although there have been automatic sewing equipment driven independently by the upper and lower heads, the upper and lower heads can be linked simultaneously by a servo system to complete the sewing action. However, ...

AI Technical Summary

Problems solved by technology

However, the upper and lower machine heads cannot rotate at the same time. Generally, only the lower machine head rotates and the upper machine head does not rotate, which cannot simulate the manual sewing process. Moreover, when reverse sewing, the sewing effect is poor and cannot meet the product design requirements.

[0006] The upper head of the traditional automatic sewing equipment cannot be raised and lowered, and cannot adapt to the thickness change of the fabric to be sewn, which limits the scope of use of the sewing equipment

The existing automatic sewing equipment does not have a presser foot, which cannot guarantee the stability of the fabric and stitches during sewing, and also reduces the scope of use of sewing equipment

[0007] The thread trimming mechanism of traditional sewing equipment is generally driven by the spindle and the cam to trim the thread with scissors. The stability is poor, the mechanism is complicated, and maintenance is troublesome.

On the other hand, when the traditional sewing equipment trims the thread, it is generally equipped with an inner thread mechanism to hold the needle thread and then trim the thread. The inner thread mechanism is complicated, maintenance is troublesome, and the failure rate is high.
