Description

Filament heating device and false twist texturing machine Technical Field The invention relates to a heating device for heating filaments such as polyester, nylon and the like, and a false twist texturing machine. Background Similar heating devices are known from the prior art document, for example from DE19631860A1. This document discloses a heating device having a recess and a cover plate for closing the recess. The groove is formed inside the heating device. The heating element designed as a heating rod is located in the bottom region of the recess. The bottom region of the groove is one of the heating surfaces. In order to prevent the filaments from contacting the groove bottom in any case, the groove bottom region is provided with a support net. The groove of the heating device is closed by a cover plate. The cover plate is designed as an insulating cover plate, so that the energy introduced into the recess by the resistive heater is transmitted to the filaments as intensively as possible. The cover plate is connected to the heating device by a rotating mechanism. The outlet area of the recess of the heating device has a chamfer, which is adapted to the chamfer on the cover plate, and the thread guide attached to the cover plate can be centered with respect to the recess when the cover plate is closed. Such a heating device is called an "open heating device", and in particular, it is characterized by being openable. The cover plate needs to be opened when the filaments are guided into the grooves. After the guiding action is completed, the cover plate is closed. The closed groove needs to have excellent insulation so that the filaments can be heated to the desired temperature in an efficient manner and the temperature deviation can be kept within a desired range. The cover plate, which is weak in heat insulation ability, is one of reasons why the heat insulation ability of the entire heating device is weak even after the groove of the heating device of such a structure is closed. In addition, the larger hollow structure between the cover plate and the heating element also weakens the overall insulating properties of the heating device. Disclosure of Invention The invention aims to provide a heating device and a false twist texturing machine, which are used for enhancing the heat insulation performance of the heating device based on the design of an open heating device in the prior art. In addition, the invention also focuses on the convenience of cleaning and maintenance of the heating device. According to an aspect of the present invention, a filament heating apparatus includes a heating apparatus body, a heating portion provided in the heating apparatus body, and a heating rail disposed along a longitudinal direction of the heating apparatus, the heating rail having an open space on a side thereof contacting the filament, the open space extending along the longitudinal direction, the heating apparatus further having a door portion and a heat insulating portion, at least the heat insulating portion being moved between a working position for filling the open space and a filament feeding position offset from the working position in an orthogonal direction orthogonal to the longitudinal direction, the heat insulating portion being moved into and out of the open space from one side of the open space during the movement. The heat insulating part extends into the open space, and the bottom surface of the heat insulating part is close to the heating track, so that the hollow space between the bottom surface of the heat insulating part and the heating track is reduced. The smaller the hollow space is, the less heat loss is, so that the temperature loss is controlled as much as possible when the filament heating work is carried out, and the heating and heat preservation efficiency is further improved. However, with respect to how the wire feeding position is set, the present invention sets the wire feeding position at a position offset from the working position in the orthogonal direction in consideration of convenience in actual cleaning, replacement and maintenance. By such a design, when the heat insulating part is positioned at the wire feeding position, the heating track can be in a state of being easy for an operator to clean, replace and maintain. According to another aspect of the present invention, the door portion and the heat insulating portion are engaged with a moving mechanism having an operation lever. According to another aspect of the invention, the movement of the at least insulation is achieved by rotating the lever. According to a further aspect of the invention, the insulation is fixed on the side of the door facing the filaments. According to yet another aspect of the present invention, the heat insulating part is spaced apart from the door part and connected by a link. According to still another aspect of the present invention, the heat insulating part has a bevel edge part inclined with
