Problems solved by technology

At present, the curling of raw fabric edges is done manually by the processor before stepping on the thread, which is inefficient, and the width of the rolled edge is likely to be inconsistent before and after, and the tangent line is also likely to be not straight, resulting in low processing quality of the product.

Embodiment 1

[0016] Embodiment 1: As shown in the figure, an automatic crimping device for a sewing machine includes a "U"-shaped first positioning plate 11 with a transverse opening and a first guide plate 12 bent inwardly of the first positioning plate 11. The lower end of a guide plate 12 is integrally connected with the lower end of the first positioning plate 11, and a first “U”-shaped guide channel 13 with a transverse opening is formed between the first guiding plate 12 and the first positioning plate 11. The first positioning The upper part of the plate 11 is fixedly connected with the first blowing pipe 3, the angle α between the first blowing pipe 3 and the upper part of the first positioning plate 11 is equal to 90°, and one end of the first blowing pipe 3 is connected to the first "U" The type guide channels 13 communicate with each other, and the other end of the first blowing pipe 3 is connected with a compressed gas control device (not shown in the figure).

Embodiment 2

[0017] Embodiment 2: As shown in the figure, an automatic hemming device for a sewing machine includes a "U"-shaped first positioning plate 11 and a second positioning plate 21 with a transverse opening, and the second positioning plate 21 is arranged on the first positioning plate 11 and the opening is facing the same direction, the upper end of the second positioning plate 21 and the lower end of the first positioning plate 11 are welded to each other, and the gap 5 of the transverse opening is provided between the first positioning plate 11 and the second positioning plate 21. The lower end of a positioning plate 11 is integrally connected with a first guide plate 12 bent inwardly of the first positioning plate 11, and a first “U” shape with a transverse opening is formed between the first guiding plate 12 and the first positioning plate 11. Guide channel 13, the upper part of the first positioning plate 11 is fixedly connected with the first air blowing pipe 3, the angle α ...

Embodiment 3

[0018] Embodiment 3: As shown in the figure, other structures are the same as Embodiment 2, except that the openings of the first positioning plate 11 and the second positioning plate 21 face opposite directions.

[0019] In the second and third embodiments above, the opening orientation of the gap 5 can be the same as the opening orientation of the first positioning plate 11, or it can be opposite. In all embodiments, the compressed gas control device adopts an existing commonly used device, which is lifted by a sewing machine. The presser foot device is connected with the gas valve to control the opening and closing of the gas, and the included angles α and β can also be less than 90°.

Abstract

The invention discloses an automatic hemming device of a sewing machine. The device is characterized by comprising at least one U-type guide device with a transverse hatch; the guide device is connected with a gas compression system which can push burr of cloth for U-type hemming; the automatic hemming device has the advantages that because the device comprises the U-type guide device with the transverse hatch and the gas compression system, as long as the cloth with the burr is transversely put in the guide device and the gas compression system is opened, the burr is pushed for automatic hemming along a U-type guide passage of the guide device without manual hemming; the automatic hemming device has a rapid hemming speed; the front and the rear of the hemmed flange have even width; the device is arranged in front of a pressure foot of the sewing machine so that the cloth is subjected to automatic hemming through the device before the sewing of tangential line; and the automatic hemming device greatly improves the working efficiency, enables the tangential line to be even and straight and ensures the processing quality of the cloth.

Description

technical field [0001] The invention relates to a device on a sewing machine, in particular to an automatic hemming device of the sewing machine. Background technique [0002] A finished garment (including clothes and trousers) is processed by different cutting and splicing of fabrics, and the original fabric basically has raw edges after cutting. In order to make the finished garment more neat and beautiful, it needs Roll the edge of the fabric downward first, and then sew the thread through the presser foot. At present, the curling of raw fabric edges is done manually by the processor before stepping on the thread, which is inefficient, and the width of the rolled edge is likely to be inconsistent before and after, and the tangent line is also likely to be not straight, resulting in low processing quality of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic crimping device of a sewing m...
