Embodiment 1

[0030] see figure 1 , This embodiment includes a housing 1, a heating liner 2, a hot rail 3, a temperature sensor 4, and a fume exhaust duct 5.

[0031] The heating inner container 2, the hot rail 3, the temperature sensor 4 and the oil fume exhaust duct 5 are arranged inside the casing 1. The housing 1 is provided with a working status indicator, which can visually display the working status of the hot box. Heat insulation material is filled between the shell 1 and the heating inner liner 2; the heating inner liner 2 is provided with a heating medium, and the heating medium is biphenyl. Biphenyl has the characteristics of good chemical stability, low cost, and stable cycle. The maximum heating temperature can reach 250°C, and its critical temperature is just below the melting point of PET, so it can effectively avoid local overheating. The outer wall of the heating liner 2 is provided with six heating element installation pipes, and the six heating elements are respectively ins...

Abstract

The invention discloses a hot-rail deformation hot box, which comprises a shell, and a heating liner container, hot rails and temperature sensors, which are arranged inside the shell; a thermal insulation material is filled between the shell and the heating liner container; heating medium is arranged inside the heating liner container, and the outer wall of the heating liner container is detachably and fixedly provided with a plurality of groups of heating elements; the quantity of the hot rails is multiple, the hot rails are fixed on the shell, one end of each hot rail is in welding connection with the heating liner container, each hot rail is of a hollow structure, and an inner cavity of each hot rail is communicated with an inner cavity of the heating liner container; and the upper end and the lower end of the heating liner container are respectively provided with one temperature sensor. The outer wall of the heating liner container is provided with the groups of heating elements, which work simultaneously, so that not only is rapidness in heating speed realized, but also a yarn path is uniformly heated.

Description

Technical field [0001] The invention relates to a hot rail type deformed hot box. Background technique [0002] The deformation hot box is the core component of modern high-speed drawing texturing machines. Modern high-speed drafting texturing machines not only have greatly changed the specifications of the yarn varieties produced compared to the past, but the processing speed has also been greatly improved. Therefore, higher requirements are also put forward for the deformation hot box of the drafting texturing machine. [0003] Although the current high-speed drafting texturing machines on the market can still meet most of the processing requirements, when processing some fine denier and high F yarns, many shortcomings have appeared, such as many broken ends, many hairs, and poor dyeing. Uniformity, etc., this has a great relationship with the deformation hot box equipped with the equipment. [0004] The structure of the deformation hot box of the traditional deformation hot box...
