Description

Technical Field

[0001] This utility model relates to the field of garment machinery technology, specifically to a front pocket machine. Background Technology

[0002] Clothing and trousers are essential daily necessities. Trousers generally have front and back pockets, serving not only to carry items but also for decorative purposes. The opening of the front pocket is usually sewn with a facing to prevent deformation and wear, and also for aesthetic purposes. In the production of the front pocket, the pocket fabric, trouser piece, and facing are first sewn together. Then, the facing is turned inside out before a second sewing. This method conceals any raw edges between the trouser piece and the facing, and makes the turned-out facing smoother. In traditional craftsmanship, the first sewing is done manually, followed by manually turning the facing inside out before the second sewing to hide the raw edges and ensure a smooth facing. This method is not only inefficient but also prone to uneven stitching and wrinkles due to improper manual operation, affecting the quality of the finished product.

[0003] With the application of automated equipment, front pocket machines integrating feeding, sewing, and hemming functions have emerged in existing technologies. After the required material is pressed together at the feeding station, it is moved to the sewing station where the machine head completes the first stitch. Then, the hemming mechanism performs edge folding and finally completes the second stitch.

[0004] However, such existing equipment also has its drawbacks: because the sewing machine head needs to move back and forth along the width of the workbench when sewing, its movement trajectory overlaps with the working area of ​​the feeding station, which makes it impossible to carry out the feeding and flanging processes synchronously. During the production process, the next process can only be started after the previous process is completely finished, resulting in idle equipment and efficiency loss.

[0005] In addition, the automatic flanging mechanism in existing equipment also suffers from drawbacks such as overly complex drive structure and loose drive layout, making it difficult to achieve a compact design.

[0006] Therefore, how to provide a new type of front bag making machine that eliminates process interference by optimizing the mechanical structure, realizes the synchronous and independent operation of the feeding and flanging stations, and improves the integration of equipment and the continuity of processing to meet the needs of high-efficiency and high-precision production is a problem that urgently needs to be solved by those skilled in the art.
