Description

Technical Field

[0001] The utility model relates to the field of clothing manufacturing, in particular to a guide device for sewing the lower edge of a shirt collar. Background Art

[0002] In the production of clothing, the quality of collar surface is directly related to the quality of the product. In order to ensure that the collar surface can cover the collar bottom after being folded, and to prevent the collar corner from curling outward after the lapel is folded, the lapel is usually processed with a nest before being put on to give the lapel a certain nest, and the collar edge of the lapel is sewn to keep the lapel at a certain curvature. The traditional manual production method is manual with experience or technical knowledge. This method requires a high level of sewing operation. For different technical employees, the collar surface produced is also different. Not only is the collar surface rough and uneven, but it also reduces production efficiency, cannot meet customer requirements, and is not suitable for mass production.

[0003] The prior art CN201320564708.0 discloses a collar foot line fixture, comprising a first template, the first template comprising a positioning portion and an inclined portion, the positioning portion is a planar structure, the inclined portion comprises a first side and a second side opposite to the first side, the first side is connected to the positioning portion, and the inclined portion is upwardly warped relative to the positioning portion. Although the utility model improves the flatness and uniformity of collar sewing by fixing and guiding the stitches, the following problems still exist:

[0004] 1. The lower end of the collar is generally arc-shaped. Under the influence of the warped part, the collar will slide toward the horizontal positioning plate at one end close to the presser foot of the sewing machine. Under the influence of the block at the clamping part, the collar is likely to tilt at both ends under the influence of weight, affecting the sewing accuracy and the final flatness of the collar.

[0005] 2. After sewing is completed, due to the obstruction of the clamping parts, the operator needs to take the sewn collar from behind the presser foot, which is extremely troublesome and affects work efficiency.

[0006] 3. The device may not fully consider the collar processing requirements of fabrics of different materials and thicknesses. The diversity of fabrics may result in the clamp not being able to apply force evenly during use, especially for thicker or harder fabrics, affecting the collar effect and even causing wrinkles or damage to the fabric during sewing. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a guide device for sewing the bottom edge of a shirt collar, which limits the edge of the collar by adopting an elastic baffle and adjusts the bending degree of the elastic baffle through an adjusting device to adapt to collars of different sizes and shapes, thereby improving the accuracy and efficiency of collar sewing.
