Problems solved by technology

When the corners of the scarf are rounded, this processing method will make the overlock quality of the rounded corners of the scarf worse, thus affecting the sewing quality of the entire scarf
The conventional technique for sewing square scarves with rounded corners is to complete the sewing of the straight edge first and then sew each rounded corner separately. However, when sewing rounded corners, the square scarf needs to be re-fixed every time a rounded corner is sewn, and the sewing efficiency is low.

Embodiment 1

[0062] Such as Figure 4 As shown, a sewing machine is used for overlocking the edge of a square towel. The sewing machine includes a control system and a mechanical system. The mechanical system includes a sewing main body, an auxiliary feeding mechanism 5 and a receiving mechanism. The control system controls the sewing of the sewing main body and controls the auxiliary Feeding mechanism 5 and receiving mechanism action. The sewing main body includes a platen 1 and a sewing machine head 4 , the platen 1 is fixed on a frame, and the frame is arranged below the platen 1 . The table top 1 is provided with a feeding area 1a, a sewing area 1c and a receiving area 1b, the sewing machine head 4 is fixed on the sewing area 1c, there are two feeding areas 1a and are respectively located on both sides of the sewing area 1c, the sewing area 1c and The feeding area 1a is located on one side of the table 1, the receiving area 1b is located on the other side of the table 1, the receiving...

Embodiment 2

[0092] The vertical distance m=80mm between the rotation angle sensor 8 and the Y axis, the stitch distance n=2.6mm when sewing the rounded corners of the square scarf, with a=360mm, b=420mm, r=80mm, θ=90°, h=1mm Take the sewing of a square scarf as an example, the length of the first side of the square scarf is 240mm, l t =m-r=0mm.

[0093] A peripheral sewing method adopts the sewing machine in the first embodiment. Include the following steps:

[0094] O. Preparation: On the platen 1 of the sewing machine, an X-Y rectangular coordinate system is established with the needle landing point as the coordinate origin O, the X-axis direction is opposite to the main feeding direction of the sewing machine, and the Y-axis direction is perpendicular to the main feeding direction;

[0095] Determine the length a=360mm and width b=420mm of the scarf, and at the same time determine the fillet radius r=80mm of the scarf, input the length a=360mm and width b=420mm of the scarf and the f...

Abstract

The invention provides a kerchief circular bead edge sewing method and a peripheral edge sewing processing method, and belongs to the technical field of sewing. According to the technical scheme, the problems that an existing kerchief circular bead edge sewing method is low in sewing efficiency, and poor in kerchief circular bead edge sewing quality are solved. The kerchief circular bead edge sewing method comprises the steps of a, the original point of a kerchief circular bead is moved to a machine needle falling point; b, a control system controls a sewing body to conduct sewing, besides, the control system controls an auxiliary feeding mechanism to drive a kerchief to conduct rotation movement W on a table board with the center of the kerchief being the rotation center, and synchronously drives the kerchief to conduct translation movement L on the table board, through the combination of the rotation movement W and the translation movement L, the position of the center of a circle of the kerchief circular bead is maintained unchanged, and the kerchief conducts rotation movement S with the center of the circle of the kerchief circular bead being the rotation center; c, after the rotation movement W is conducted and the kerchief rotates by theta degrees, edge sewing of the kerchief is finished. According to the kerchief circular bead edge sewing method and the peripheral edge sewing processing method, the sewing quality of edge sewing of the kerchief circular bead is guaranteed, and meanwhile the sewing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of sewing technology, and relates to a square scarf rounded edge seam method and a peripheral seam processing method. Background technique [0002] The square scarf is a rectangular or square sewing material. After the square scarf is cut, it needs to be overlocked on the edge of the square scarf. The four corners of the square scarf are right angles or rounded. [0003] Sewing machine is exactly the machine that stitches sewing material by suture. Sewing machines include lockstitch sewing machines, chain sewing machines, overlock sewing machines, interlock sewing machines and buttonhole machines, etc. Overlock sewing machine refers to a sewing machine that completes overlock sewing. Overlock sewing refers to the sewing that the pointer thread and the looper thread are self-connected and interconnected, and the sewing material is hemmed or stitched. Ordinary sewing machines include a sewing body, which includes a ne...
