Description

Technical Field

[0001] The utility model relates to the field of interlock sewing machines, and more specifically, to a continuous sewing guide mechanism for elastic hidden seam strips. Background Art

[0002] The interlock sewing machine, full name interlock sewing machine, is an industrial sewing machine specially used to sew two or more layers of sewing materials. It mainly uses needle and shuttle to make the shuttle thread form a single-sided covered chain stitch on the bottom of the sewing material, or adds a covering line on the front of the sewing material to form a double-sided covered chain stitch. The covering line on the front of the double-sided covered chain stitch mainly serves as a decorative aesthetic. In the sewing of trousers, the side seams and crotch seams of the trousers are sewn by interlock sewing machines. Generally, the single-sided sewing process is adopted. There will be two seams on the inside of the trousers. For some more expensive trousers, the existence of the seams will appear to be not upscale. At the same time, for rougher fabrics such as denim, the seams on the inside of the trousers will affect the comfort of wearing. As people's requirements for clothing comfort and detail quality are getting higher and higher, some manufacturers have also begun to sew an elastic hidden seam strip on the two seams on the inside of the trousers to cover the seams. However, the elastic hidden seam strip needs to be sewn continuously, and the movement of the elastic hidden seam strip needs to be guided. However, there is a lack of a special continuous sewing guide mechanism for the elastic hidden seam strip on the market. Since the elastic hidden seam strip has a certain width, the common sewing machine thread guide is not applicable. Utility Model Content

[0019] Figure 1-Figure 2 An elastic hidden seam strip continuous sewing guide mechanism provided in an embodiment of the utility model is used in a flat seam sewing machine, comprising:

[0020] A material guide plate 1 is arranged at the lower end of a worktable 2 of a flat sewing machine, and a material guide channel corresponding to the elastic hidden seam strip is arranged on the material guide plate 1;

[0021] The limiting member 3 is arranged at the end of the workbench 2 of the interlock sewing machine, and a limiting hole corresponding to the elastic hidden seam strip is vertically arranged on the limiting member 3.

[0022] In this embodiment, the elastic hidden seam strip is pre-wound on the unwinding device, and the unwinding device can adopt the existing technology. The elastic hidden seam strip is continuously unwound by the unwinding device, and the end of the unwound elastic hidden seam strip passes through the material guide channel on the material guide plate 1, and then passes through the limit hole on the limiter 3, and finally enters the workbench 2 of the interlock sewing machine. When the interlock sewing machine is working, it will drive the elastic hidden seam strip to move upward, thereby driving the elastic hidden seam strip unwound by the unwinding device to move, and the moving trajectory of the unwound elastic hidden seam strip is guided by the material guide plate 1 and the limiter 3.

[0023] Preferably, as another embodiment of the present utility model, Figure 3 As shown, the material guide plate 1 comprises a vertically arranged first part 11, an inclinedly arranged second part 12 and a horizontally arranged third part 13, and the two ends of the second part 12 are respectively connected to the first part 11 and the third part 13. The first part 11, the second part 12 and the third part 13 are provided with a material guide groove 14 corresponding to the elastic hidden seam strip at one end away from the interlock sewing machine worktable 2, and a plurality of limit plates 15 are provided at the upper end of the material guide groove 14, and the material guide groove 14 and the limit plates 15 together constitute the material guide channel.

[0024] In this embodiment, the elastic hidden seam strip passes through the guide grooves 14 on the first part 11, the second part 12 and the third part 13 in sequence, and the elastic hidden seam strip in the guide groove 14 is blocked by a plurality of stop plates 15 on the guide groove 14 to prevent the elastic hidden seam strip from falling from the guide plate 1. The opening of the guide groove 14 faces downward and is not completely sealed. Compared with a closed guide mechanism, it is convenient to manually pull the end of the elastic hidden seam strip through the guide channel on the guide plate 1.

[0025] Preferably, as another embodiment of the utility model, it also includes:

[0026] The wire barrel is vertically arranged below the first portion 11 .

[0027] In this embodiment, since the interlock sewing machine is generally installed on an operating table, the guide wire barrel is vertically passed through the operating table and fixed thereto, and the end of the elastic hidden seam strip is passed upward through the guide wire barrel and quickly sent into the material guide channel.

[0028] Preferably, as another embodiment of the utility model, the outer shell of the interlock sewing machine workbench 2 is provided with an upper through hole 5 and a lower through hole 6 corresponding to the limit member 3 and the material guide plate 1 respectively, and the upper through hole 5, the lower through hole 6 and the outer shell bracket of the interlock sewing machine workbench 2 together constitute a channel for the elastic hidden seam strip to pass through.

[0029] In this embodiment, the elastic hidden seam strip coming out of the guide plate 1 will rub against the right angle of the end of the stretch sewing machine worktable 2 before entering the limiting member 3. In order to reduce the friction of the elastic hidden seam strip, an upper through hole 5 and a lower through hole 6 are provided on the outer shell of the stretch sewing machine worktable 2. After the elastic hidden seam strip comes out of the guide plate 1, it passes through the lower through hole 6 and the upper through hole 5 in turn, and then enters the limiting member 3, thereby avoiding the elastic hidden seam strip from rubbing against the right angle of the end of the stretch sewing machine worktable 2.
