Description

Technical Field

[0001] The utility model relates to the technical field of flat seaming machines, and more specifically, to a folding device on a flat seaming machine. Background Art

[0002] The stretch sewing machine is also called a special sewing machine. It produces chain sewing stitches and is mostly used for collar rolling, hemming, folding hems, stretch seams, splicing seams and trimmings on clothing. It is an essential sewing equipment for large production factories, especially for the bottom edges and cuffs of knitted garments, which generally use stretch seams and folding edges. In order to make the folding edges more beautiful, decorative strips are added to the stretch seams.

[0003] At present, a Chinese patent with application number CN202220782530.6 discloses a stretch sewing device with uniform folding edges, including a stretch sewing machine, which is provided with a table top, a side guard is provided on the table top, and a lighting lamp is fixed under the table top; flame-retardant paper is pasted on the side of the stretch sewing machine; the side guard is composed of a folding edge A and a folding edge B, and the width between the folding edge A and the folding edge B is the folding edge width; the folding edge A is fixed on the table top, and the folding edge B is movably connected to the table top, and a one-time stretch sewing folding edge can be completed. Although the folding edge width can be adjusted, the structure is too simple, the folded edge fabric is easy to slip, and the size of the folding edge cannot be accurately controlled. When the fabric is folding, the fabric must be manually pressed on one side and continuously pushed in to perform the folding operation. If a decorative sticker is to be added, the operation needs to be repeated on the stretch sewing line, which increases the workload and is very inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Reference Figures 1 to 4 The embodiments of the utility model are further described.

[0019] A folding device on a stretch sewing machine includes a folding mechanism and an adjusting mechanism, both of which are placed on the stretch sewing machine. The folding mechanism includes a base plate 6, two guide strips 7, a movable plate 8, a fixed plate 9, a bending plate 10, a limit plate 11 and an adjusting bolt 13. The two guide strips 7 are fixed on the base plate 6 in parallel, the movable plate 8 is placed between the two guide strips 7 and is slidably connected to the guide strips 7, the fixed plate 9 is N-shaped, the fixed plate 9 is fixed on the two guide strips 7, a threaded hole is provided on the fixed plate 3, the adjusting bolt 13 is threadedly connected to the threaded hole and the end of the adjusting bolt 13 is against the movable strip 8.

[0020] A positioning piece 12 is fixed at one end of the bottom film 6, and a bending piece 10 and a limiting piece 11 are respectively fixed at two ends of the movable piece 8. A folding space is formed between the positioning piece 12 and the bending piece 10. By pulling the movable piece 8 to slide along the guide strip, the spacing between the bending piece 10 and the positioning piece 12 is changed, and the size of the fabric folding space is adjusted to adjust the folding space. The limiting piece 11 can be abutted against one side of the fixed plate 9 to prevent the movable piece 8 from falling off. A scale 17 is provided on one of the guide strips 7 to facilitate the measurement of the folding size. When sliding to the required size, the adjusting bolt 13 is rotated so that the bottom end of the adjusting bolt 13 presses the movable piece 8 against the bottom film 6 to limit the folding size.

[0021] The adjusting mechanism includes a pull tube 1, a connecting piece 2, a fixed plate 3, a rotating shaft 4, a rotating piece 5 and a connecting piece. The connecting piece 2 is fixed to one side of the pull tube 1, and a strip-shaped connecting hole 201 is opened on the connecting piece 2, and a reserved screw hole 301 is opened on the fixed plate 3. The fixed plate 3 can be fixed to the stretch sewing machine by screws. One end of the rotating shaft 4 is fixedly connected to the fixed plate 3, and a circular hole is opened on the rotating piece 5. The other end of the rotating shaft 9 passes through the circular hole and is rotatably connected to the circular hole. A strip hole 501 is opened on the rotating piece 5. The rotating piece 5 is moved so that the rotating piece 5 rotates relative to the fixed plate 3 around the rotating shaft 9. The rotating piece 5 can be placed on the connecting piece 2, and the strip hole 501 on the rotating piece 2 overlaps with the connecting hole 201 on the connecting piece 2. The pull tube 1 can roll up and guide the decorative strip. The pull tube 1 is superimposed on the folding space of the bottom film 6 for use, which can facilitate the addition of decorative strips to the fabric while stretch sewing, so that the addition of decorative strips to the stretch seam line can be completed in one step.

[0022] The connecting piece includes a lever 14 and an adjusting block 15. The lever 14 and the adjusting block are fixedly connected. The adjusting block 15 can be placed in the connecting hole 201 and the strip hole 501 at the same time. An elastic clamp 16 is sleeved on the adjusting block 15. Pushing the lever 14 downward causes the adjusting block 15 and the elastic clamp 16 to be clamped in the connecting hole 201, so that the connecting piece 2 and the rotating piece 5 can be relatively locked. The position height of the pull tube 1 can be adjusted by shifting the rotating piece 5 to adapt to the folding edge of the fabric. Pulling the lever 14 and the adjusting block 15 upward can cause the elastic clamp 16 to escape from the strip hole 501 and be placed in the connecting hole 201, so that the connecting piece 2 and the rotating piece 5 are unlocked and can be moved to an adjustable position.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
