Description

Technical Field

[0001] This invention relates to the field of sewing machine technology, and more particularly to an automatic correction and feeding sewing machine. Background Technology

[0002] In the production and processing of clothing, underwear, and trousers, elastic bands are often sewn onto the fabric surface to achieve functions such as elastic cuffs and elastic waistbands. Traditional elastic band sewing mostly relies on manual feeding, where the fabric and elastic band are aligned and aligned. This has the following obvious drawbacks: First, the fabric is prone to deviation: manual feeding makes it difficult to ensure that the fabric enters the sewing position straight, easily resulting in skewing and offset, leading to crooked elastic bands, wrinkles, uneven edge distances, and a high defect rate. Second, the elastic band and fabric are not synchronized: manual feeding easily leads to inconsistent speeds and uneven stretching between the fabric and elastic bands, causing the elastic bands to pile up and deform, affecting the product's elasticity and appearance. Third, it is inconvenient to adjust and has poor versatility: traditional equipment lacks multi-dimensional adjustment structures for height, front and back, and left and right, making it unable to adapt to fabrics and elastic bands of different thicknesses, widths, and materials, and making adjustments for different styles time-consuming and labor-intensive. Fourth, the degree of automation is low: relying on manual feeding is labor-intensive and inefficient, making it difficult to meet the needs of continuous and standardized production.

[0003] While existing technologies have some material feeding auxiliary structures, most of them only have simple guiding functions and lack dual-level automatic correction, multi-dimensional position adjustment and synchronous feeding and coordination structure of cloth and elastic band. They cannot fundamentally solve the problems of deviation, asynchrony and complicated adjustment.

[0004] Therefore, the industry urgently needs an automatic correction and feeding sewing machine that can automatically correct deviations, feed materials synchronously, be easy to adjust, and ensure stable sewing. Summary of the Invention

[0005] In view of this, it is necessary to provide an automatic correction feeding sewing machine that, through the coordinated design of an arc-shaped bracket and a double-layer acrylic plate refraction plate, can achieve blind-angle and shadowless illumination of the curved surface being measured, thereby improving the integrity and clarity of the information collected by the camera module.
