Problems solved by technology

[0003] (1) The heating temperature is low, and the maximum temperature can only be controlled at 270-290°. If the temperature is higher, the gas pressure in the container will be increased and the safety factor will be reduced;
[0004] (2) Liquid biphenyl heats up slowly, and it takes at least 6 hours of heating before work to reach the process temperature. At the same time, biphenyl is a toxic chemical substance. Once leaked, it will hinder human health and environmental protection;
[0005] (3) It takes about 0.2 seconds to heat the wire in the hot box to reach the process temperature r

Embodiment Construction

[0024] Below in conjunction with accompanying drawing, embodiment of the present invention is described in further detail:

[0025] The present invention comprises box body 11, and box body 11 is cuboid, and its box body 11 is provided with electric heating rod 7, hot rail 5, heat spreader 6, temperature measuring device 10 and insulation material 9. The heat spreader 6 is a copper heat conductor, and the electric heating rod 7 and the hot rail 5 are respectively embedded in the grooves of the heat spreader 6 , and are fixed in the box body 11 by the heat spreader 6 . In order to replace the electric heating rod 7 conveniently, the lower side of the electric heater 6 is also provided with a heat spreader bottom cover 8 for loading and unloading the electric heating rod 7 . An insulating material 9 is filled between the heat spreader 6 and the box body 11 . In order to effectively test and observe the temperature in the casing 11, a temperature detector 10 is also provided in ...

Abstract

The invention relates a to false-twist texturing machine high temperature box. It is made up of box body, heat rail, heat transmitter, and heat insulating material. Electrical bar and heat rail is in heat transmitter and fixed in box body. The heat rail is formed by two parallel long and short heat rails. The box body is set thermal detector. The invention has the advantages of short preheating time, fast heating, safe, reliable, and the 625 centigrade degree maximum working temperature; small box body size; short yarn waling length; and good quality and performance stretch yarn.

Description

technical field [0001] The invention relates to a chemical fiber machine, in particular to a high-temperature heat box of a false twist texturing machine used for heating and texturing fiber filaments. Background technique [0002] This hot box is also a heating device, which can heat and deform chemical fiber elastic yarn (POY yarn). During the working process, the fed chemical fiber elastic yarn is heated to a plasticized state, drawn and false twisted at the same time. After being heated and deformed, the twisted and deformed filaments are cooled and fixed by the cooling plate after leaving the hot box. The temperature setting of the heating device is determined according to the quality of the required textured yarn, the fineness of the original yarn, the running speed of the filament, the length of the heating device and its heating method, etc., which is very important for the quality and processing stability of the stretched textured yarn. influences. At present, th...
