Technical Field

[0001] The utility model relates to the technical field of melt-blowing machines, in particular to a hot runner system for a die head of a melt-blowing machine. Background Art

[0002] Meltblowing is a commonly used textile method for producing nonwoven fabrics. Generally, high-speed hot air flows in cross directions are used to draw and solidify the polymer extruded from the die hole.

[0003] The die head of the meltblown machine is one of the core components of the meltblown nonwoven fabric production process. However, the traditional meltblown die head is not equipped with a hot runner system. Instead, the entire meltblown die head is heated by a heating element. This has high energy consumption, inaccurate flow channel temperature control, poor glue uniformity, and the quality of the finished fabrics is difficult to control.

[0004] An existing patent (publication number: CN 213447396 U) discloses a hot runner system for a meltblowing machine die head, including a main nozzle. A hot runner system is added to the meltblowing machine die head, and the entire meltblowing machine die head is heated by a heating element. Heating elements are installed on the outer walls of the main nozzle, the flow plate and the hot nozzle. Each heating element can heat the main nozzle, the flow plate and the hot nozzle separately and separately, and can accurately control the temperature of the entire polymer flow channel to improve the uniformity and toughness of the output wire and ensure the quality of the finished cloth.

[0005] However, the above technical solution still has certain defects.
