Description

Technical Field

[0001] The utility model relates to the field of textile cloth setting machines, in particular to a hot air circulation system for a tentering setting machine. Background Art

[0002] In the textile industry, the stenter machine plays a vital role as the core equipment for fabric processing. Through heating, stretching and shaping, the equipment ensures that the fabric reaches the predetermined size specifications and appearance to meet market demand. However, although the traditional stenter machine plays an important role in textile production, its heating and shaping process faces many challenges.

[0003] First of all, low efficiency of heat energy utilization is a significant problem of traditional stenter setting machines. During the heating process, due to imperfect insulation measures or design defects, a large amount of heat energy is easily lost to the surrounding environment, resulting in serious energy waste. This not only increases the energy consumption cost of the enterprise, but also creates an unnecessary burden on the environment.

[0004] Secondly, uneven heating is another problem that needs to be solved. When heating fabrics, traditional stentering machines often have difficulty in achieving uniform distribution of hot air. This causes the fabric to be partially overheated or overcooled during the heating process, which in turn affects the overall shaping effect and quality of the fabric. Uneven heating may also cause problems such as deformation, shrinkage or color difference of the fabric, reducing the market competitiveness of the product.

[0005] In addition, high energy consumption is also a serious challenge faced by traditional stenter setting machines. Due to problems such as low thermal energy utilization efficiency and uneven heating, the equipment needs to consume a lot of energy to maintain normal working conditions during operation. This not only increases the operating costs of the enterprise, but also limits the potential of the equipment in energy conservation and emission reduction. Utility Model Content
