Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing, and more specifically, to a cloth button sewing machine. Background Art

[0002] In the modern clothing manufacturing industry, button sewing is an indispensable process, and its quality and efficiency directly affect the quality and production progress of clothing. As the key equipment for realizing automated button sewing, the cloth button sewing machine plays an important role in improving production efficiency and ensuring the quality of button sewing. However, in the existing cloth button sewing machines, the connection and disassembly operations between the clamping head responsible for button sewing and the overall equipment are often complicated and time-consuming. The clamping head is one of the key components of the button sewing machine. Its function is to clamp the button and accurately send it to the designated position of the cloth for sewing. In actual production, since different models and specifications of buttons require different clamping heads, the clamping heads need to be replaced frequently to meet production needs. However, the existing button sewing machines are inconvenient in the installation and disassembly of the clamping heads. Some models use bolt connection, which requires tools for assembly and disassembly. The operation is cumbersome and inefficient, and the clamping head cannot be quickly replaced. This not only increases the downtime of the equipment and affects the production rhythm, but also brings unnecessary workload to the operators.

[0003] Secondly, in the button sewing process, the clamping and positioning of the fabric is a key link. Only by accurately and flatly fixing the fabric at the button sewing position can the position accuracy and the quality of the button sewing be guaranteed. However, the existing button sewing machines have shortcomings in the clamping and positioning of the fabric. Many models lack a special fabric clamping mechanism and cannot reliably fix and tension the fabric, which causes the fabric to easily move and wrinkle during the button sewing process, affecting the quality of the button sewing. Some models require manual assistance from the operator to fix and tension the fabric by hand before sewing the buttons, which is not only inefficient, but also easily causes increased labor intensity and hand fatigue injuries.

[0004] In addition, fabric button sewing machines also face the problem of insufficient adaptability in practical applications. Most existing button sewing machines adopt a fixed height design, that is, the height of the machine body cannot be adjusted and can only adapt to production lines of specific heights. However, in actual production, the heights of different clothing production lines and processing sites may be different. If the height of the button sewing machine cannot be flexibly adjusted, it will not be able to adapt to the height requirements of different production lines, resulting in the inability to flexibly switch and share the equipment between different production lines, affecting the flexibility of production and the utilization of equipment. At the same time, the fixed height design is not conducive to the movement and rearrangement of the button sewing machine, limiting its flexible layout in the workshop and its ability to quickly respond to production needs.
