Description

Technical Field

[0001] This application relates to the field of garment production equipment technology, and in particular to an intelligent and efficient garment sewing production line. Background Technology

[0002] In today's garment manufacturing industry, despite the widespread adoption of digital and intelligent production concepts, a significant amount of manual labor still exists in the garment sewing process. Traditional garment sewing relies on manual cutting of garment pieces, single-piece sewing, manual stuffing (for cotton-padded clothing), manual marking of seams, and stitching line by line. This not only consumes a large amount of manpower but also leads to high production costs and extremely low efficiency. For example, in the process of garment piece production, manually sewing the basic garment pieces (including the back piece, two front pieces, two sleeves, and collar) requires multiple tedious steps, with only one task completed at a time at each workstation. This results in long sewing times and difficulty in consistently controlling quality. Due to the limitations of manual operation, problems such as crooked threads and misaligned seams easily occur, leading to a high rate of defective products. This not only wastes materials but also severely weakens the company's competitiveness in the market.

[0003] Furthermore, existing sewing equipment mostly employs a traditional fixed sewing head combined with manual template movement to sew garments, such as template machines. The concept is to use a template to clamp the fabric, replacing manual operation. However, the template's range is limited, moving only horizontally across the table, and sewing can only be completed with a single sewing head. Essentially, it's still a simple improvement on manual sewing. This type of equipment can sew a maximum of two garment pieces at a time and requires frequent manual template changes, resulting in limited efficiency gains and failing to meet the demands of modern garment manufacturing for efficient, high-quality production. Simultaneously, post-production processing steps, such as ironing, thread trimming, and quality inspection, are also primarily done manually, resulting in a huge workload, long processing times, and high labor costs, significantly impacting product delivery cycles and the company's economic benefits. Therefore, there is an urgent need for a garment sewing production line capable of achieving AI-powered production to solve these problems. Utility Model Content

[0041] The following is a specific implementation process using the production of a regular cotton-padded coat as an example:

[0042] 1. Garment Piece Production: The entire roll of fabric is installed on the upper fabric shaft 1, the cotton roll is installed on the middle filling shaft 2, and the lining is installed on the lower lining shaft 3. The garment piece sewing machine is started, and each feeding shaft is unwound synchronously under the action of the drive motor. The fabric enters the sewing area through the upper pressure roller 4 and the lower pressure roller 5. In the sewing area, 2-5 sets of movable CNC sewing machine heads move on the three-dimensional moving guide rail according to the preset program to sew the fabric in a longitudinal and transverse arrangement. Multiple large-sized garment front pieces can be sewn at one time. After sewing, the fabric enters the pocket opening area, the binding area and the die-cutting area in sequence to complete the processes of opening the pocket, upper pocket lining, binding and die-cutting.
