Description

Technical Field

[0001] This utility model belongs to the field of texturing machine technology, and in particular relates to an installation structure for an openable heat-insulating and leak-proof temperature chamber door of a texturing machine. Background Technology

[0002] A texturing machine is a textile machine that processes synthetic fibers into elastic yarns through false twisting. During the operation of a texturing machine, the heating process has a significant impact on the quality of the final finished yarn. The existing open-type texturing machine's heating chamber structure includes: a heating chamber body filled with insulation cotton, several evenly arranged heating rails and a heating chamber door, with a reflector installed inside the door. However, the existing door structure cannot effectively secure the reflector or provide an effective seal. During operation, the heating chamber is installed at an angle on top of the texturing machine. When the heating chamber door is closed, there is a large gap between the door and the heating rails. The door is closed using a hard metal-to-metal contact method without a seal, increasing energy consumption and hindering energy conservation. Furthermore, it negatively impacts the quality of the processed yarn.

[0003] Texturing machines, as crucial machinery in the textile and chemical fiber industry, suffer from high energy consumption, a major pain point for enterprises. Energy consumption per ton of yarn has become a key performance indicator, forcing texturing machine manufacturers and supporting suppliers to develop highly efficient and energy-saving equipment and components, thus driving overall technological progress in the industry. The heating chamber, a major energy-consuming component of the texturing machine, operates at around 200℃. Existing heating chamber doors suffer from air leakage and direct heat leakage, drawing significant attention from users. The development of new, energy-efficient, openable heating chamber doors, without compromising installation, operation, or routine maintenance, has become the most pressing need for texturing manufacturers and users of texturing machines.
