Three-needle five-thread streamline covering stitch apparatus for sewing school uniform

Abstract

The invention relates to the technical field of a covering stitch device, and discloses three-needle five-thread streamline covering stitch apparatus for sewing a school uniform. The three-needle five-thread streamline covering stitch apparatus comprises a machine body, wherein both the front surface and the back surface of the machine body are respectively provided with an elongated opening, thebottom of the left side of the machine body is fixedly provided with a side box, a driving motor is fixedly installed inside the side box, the other end of an output shaft of the driving motor is fixedly sleeved with a rotating shaft, and the other end of the rotating shaft penetrates through the machine body and extends out of the machine body. The three-needle five-thread streamline covering stitch apparatus for sewing the school uniform is provided with a cloth winding roll, a cloth unwinding roll, a driven roller and a bottom wheel, so that by virtue of the cooperation of the cloth unwinding roll, the cloth winding roll, the driven roller and the bottom wheel, not only can the stretching extension for the cloth be realized, but also cloth can be flattened, the step for stretching the cloth by the operation personnel can be avoided, the qualification rate of products can be improved, and the practicability of the apparatus can be improved.

Description

technical field [0001] The invention relates to the technical field of flat seam equipment, in particular to a three-needle and five-thread streamlined flat seam device used for sewing school uniforms. Background technique [0002] Interlock sewing machine is also called special sewing machine. The stitches it sew are chain sewing stitches, which are mostly used for rolling collars, piping, hemming, flat seams, splicing seams and trims of knitted garments. [0003] However, when the existing three-needle and five-thread interlock sewing device is in operation, the operator needs to constantly pull and unfold the fabric by hand, so that the sewing is more compact and orderly, and this sewing method not only makes the pulling force It is difficult to control, and different operators have different technical levels, which easily leads to uneven sewing and large product quality deviations, which brings troubles to subsequent quality inspection work. Moreover, the height of the e...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a three-needle and five-thread streamlined stretch seam device for school uniforms, which has the advantages of automatically stretching and stretching the fabric and adjusting the height, and solves the problem of the existing three-needle and five-thread stretch seam. When the sewing device is running, the operator needs to keep pulling and unfolding the fabric by hand, so that the sewing is more compact and orderly, and this sewing method not only makes it difficult to control the pulling force, but also different operators have different Different technical levels can easily lead to uneven sewing and large product quality deviations, which will cause troubles for subsequent quality inspections. In addition, the height of the existing interlock sewing devices is generally fixed and cannot be adjusted according to the height of the operator. The adjustment makes it inconvenient for the operator to work, and it is easy to produce inferior products when sewing, which reduces the work efficiency of the operator.
