Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machinery, and in particular to a deformation heat box and a false twist texturing machine. BACKGROUND

[0002] The false twist texturing machine is a chemical fiber yarn processing equipment for processing elastic yarn from pre-oriented yarn or drawn yarn of polyester, nylon, etc. Before the raw yarn is twisted by the false twister, it needs to be heated by a deformation heat box (for example, a biphenyl heating box). The Chinese utility model patent with the publication number CN210657303U discloses an energy-saving heat box, which comprises a hot rail, a box shell, a hot door shell, a connecting block is installed on the inner side of the hot door shell, one side of the connecting block facing the hot rail is provided with a reflecting film, the reflecting film is matched with the outer shape of the hot rail, and the distance between the reflecting film and the hot rail is 5-12 mm. The Chinese utility model patent with the publication number CN210657302U discloses an energy-saving structure of a deformation heat box, which comprises a hot rail, a box shell, a hot door shell, a hot rail heat insulation layer is arranged on the two side surfaces of the hot rail, a box heat insulation layer is arranged on the box shell, and a hot door heat insulation layer is arranged on the hot door shell, and the hot rail heat insulation layer, the box heat insulation layer and the hot door heat insulation layer form a hot rail heat cavity which is closed on four sides.

[0003] However, in the above-mentioned existing energy-saving heat box (CN210657303U), the box shell is bent to form a folded plate extending into the hot cavity, so that the high temperature emitted by the hot rail is directly conducted to the surface metal plate of the box shell through the folded plate, forming a large area of radiation heat dissipation, resulting in heat loss in the heat box, which not only reduces the overall energy efficiency of the heat box, but also increases the energy consumption. Although the energy-saving structure of the deformation heat box (CN210657302U) solves the problem of heat loss of the existing deformation heat box by arranging heat insulation elements on the components that are easy to dissipate heat, such as the hot rail, the box shell and the hot door shell, but the shell cancels the traditional folded plate and does not design a replacement support structure, and one of the main functions of the original folded plate is to support and fix the heat insulation material in the heat box. In the energy-saving structure of the deformation heat box, there is no positioning or supporting component between the hot rail heat insulation layer and the box heat insulation layer, and the connection between them is only dependent on the connection with the hot rail, the box shell and the hot door shell to maintain the connection. Since the heat box is in a high-temperature and continuous vibration environment for a long time, the connection between the hot rail heat insulation layer and the box heat insulation layer is prone to dislocation and loosening due to vibration impact, and then friction and collision occur, resulting in the surface layer of the heat insulation material falling off and producing debris, which may fall into the surface of the hot rail or the fiber channel, directly polluting the fibers being processed in the heat box and affecting the product quality.

The lines shown in the drawings of the present application can be understood as members having a certain actual thickness. The term "first direction" refers to the direction indicated by the X-axis in the drawings of the present application, i.e., the thickness direction of the oven body 10.

The term "third direction" refers to the direction indicated by the Z-axis in the drawings of the present application, i.e., the length direction of the oven body 10. Figure 27 Figure 27 Figure 27

[0058] Please refer to Figures 1 to 27 A number of specific embodiments of a texturing oven are disclosed, and the texturing oven 100 in each embodiment of the present application is a biphenyl texturing oven.

[0059] As Figure 1 indicated in the drawings, an example of a texturing oven 100 (hereinafter or simply referred to as "oven 100") according to the present application. The oven 100 comprises: an oven body 10, a heat preservation structure 40 filled inside the oven body 10; the heat preservation structure 40 comprises: a first heat preservation layer 41 and a second heat preservation layer 42, the first heat preservation layer 41 is configured with a heat preservation groove 45 extending along the third direction, and the second heat preservation layer 42 is at least attached to two first side walls 411 of the first heat preservation layer 41 exposed to the heat preservation groove 45 and oppositely arranged; the oven body 10 comprises a front cover plate 11 forming a strip-shaped opening 13 exposing the heat preservation groove 45; an oven door 20 pivotally connected with the front cover plate 11 to move to open and close the strip-shaped opening 13; a hot rail 50, two second side walls 51 oppositely arranged along the second direction at least abutting against the second heat preservation layer 42; a first fixing assembly 60 for maintaining the relative position of the first heat preservation layer 41 and the second heat preservation layer 42, the first fixing assembly 60 is separated from the front cover plate 11 to partially expose the second heat preservation layer 42.

[0060] The first heat preservation layer 41 is configured with a heat preservation groove 45 extending along the third direction (as Figure 3 and Figure 4 ​​​The heat rail 50 is arranged in the heat preservation groove 45, and the second heat preservation layer 42 is attached to at least two first side walls 411 of the first heat preservation layer 41. The first heat preservation layer 41 and the second heat preservation layer 42 cooperatively form a double-layer heat preservation and insulation structure in the box body 10 to reduce heat loss inside the box body 10. The front cover plate 11 is provided with a strip-shaped opening 13 corresponding to the heat preservation groove 45. The box door 20 is connected to the front cover plate 11 through a hinge or other pivoting structure to open and close the strip-shaped opening 13. The strip-shaped opening 13 is sealed when the heat box 100 is in operation to reduce heat leakage from the heat preservation groove 45 and facilitate flexible opening in the maintenance scenario. The second heat preservation layer 42 is attached to the first side wall 411 of the first heat preservation layer 41, and the relative position of the first heat preservation layer 41 and the second heat preservation layer 42 is kept stable by the first fixing assembly 60. This can prevent the first heat preservation layer 41 and the second heat preservation layer 42 from relative displacement, loosening or shifting to the center of the heat preservation groove 45 under the high temperature of about 185℃ and the continuous vibration environment of the equipment (i.e., the false twist texturing machine 1000). At the same time, the second heat preservation layer 42 is attached to the first side wall 411. Even if debris is generated at the joint of the first heat preservation layer 41 and the second heat preservation layer 42 due to friction, the debris will be blocked in the attached area between the first heat preservation layer 41 and the second heat preservation layer 42, preventing the debris from spreading to the heat preservation groove 45 and the heat rail 50 to pollute the fiber, thereby ensuring the fiber processing quality. The heat rail 50 is in contact with the heat insulation surface 421 of the second heat preservation layer 42 along the two second side walls 51 opposite in the second direction. Thus, the second heat preservation layer 42 is laterally supported, further preventing the second heat preservation layer 42 from shifting to the center of the heat preservation groove 45. At the same time, the friction force generated by the contact surface of the second heat preservation layer 42 and the heat rail 50 can limit the vibration amplitude of the heat rail 50, so that the second heat preservation layer 42 and the heat rail 50 form a stable cooperation, further avoiding loosening between the first heat preservation layer 41 and the second heat preservation layer 42 due to equipment vibration. In addition, the first fixing assembly 60 and the front cover plate 11 are both made of metal. If the first fixing assembly 60 contacts the front cover plate 11, a metal heat conduction path will be formed. The front cover plate 11 is the exposed shell of the box body 10. If heat is absorbed through the heat conduction path, the front cover plate 11 will radiate heat to the outside. The first fixing assembly 60 is separated from the front cover plate 11 to prevent the formation of a metal heat conduction path from the first fixing assembly 60 to the front cover plate 11, thereby preventing the rapid conduction of heat from the inside of the box body 10 to the front cover plate 11, preventing the front cover plate 11 from being heated, reducing heat loss caused by radiation, and improving the energy utilization efficiency of the heat box 100 and reducing energy consumption in the production process.

[0061] Meanwhile, the first fixing assembly 60 keeps the relative position of the first heat preservation layer 41 and the second heat preservation layer 42, and is separated from the front cover plate 11, so that the second heat preservation layer 42 is at least partially exposed to form a heat insulation surface 421 facing the heat preservation groove 45, which ensures the stable effect of the first fixing assembly 60 on the relative position of the first heat preservation layer 41 and the second heat preservation layer 42, and avoids that the first fixing assembly 60 completely covers the heat insulation surface 421 to prevent affecting the heat insulation performance of the second heat preservation layer 42.

[0062] For example, the second heat preservation layer 42 can be attached to two first side walls 411 of the first heat preservation layer 41 exposed to and opposite to the heat preservation groove 45 (as shown in FIG. 1) or can be extended along the first side wall 411 between the front cover plate 11 and the first heat preservation layer 41 (not shown in the figure) on the basis of being attached to the two first side walls 411 to further fill the gap between the front cover plate 11 and the first heat preservation layer 41 and improve the overall sealing and heat preservation performance and the effect of intercepting debris. Figure 3 In addition, the second heat preservation layer 42 can be extended along the first side wall 411 between the bottom of the hot rail 50 and the first heat preservation layer 41 (not shown in the figure) after being attached to the first side wall 411 to limit and support the bottom of the hot rail 50, further reduce the vibration amplitude of the hot rail 50, and improve the heat insulation effect of the bottom of the heat preservation groove 45. The second heat preservation layer 42 of the present application is preferably attached to only two first side walls 411 of the first heat preservation layer 41 exposed to and opposite to the heat preservation groove 45, so as to achieve the heat preservation of the box body 10 and the lateral support of the hot rail 50 with a simple structure, balance the heat preservation effect and the assembly convenience of the hot box 100.

[0063] In some examples, the second heat preservation layer 42 can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 (as shown in FIG. 1) or can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 and the hot rail 50 (not shown in the figure). Figure 7 In some examples, the second heat preservation layer 42 can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 (as shown in FIG. 1) or can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 and the hot rail 50 (not shown in the figure). Figure 8 As shown in FIG. 1, the second heat preservation layer 42 is separated from the plane where the bottom of the hot rail 50 is located, the second heat preservation layer 42 is attached to part of the second side wall 51, and part of the second side wall 51 abuts against the first heat preservation layer 41. The second side wall 51 can abut against the first heat preservation layer 41 and the second heat preservation layer 42 at the same time, and the abutting positions of the second side wall 51 and the second heat preservation layer 42 are in close contact, which avoids that the cleaning liquid seeps into the first heat preservation layer 41 through the gap between the second side wall 51 and the second heat preservation layer 42 during the later cleaning and maintenance of the hot rail 50, avoids affecting the heat preservation performance of the first heat preservation layer 41, prevents the debris generated by the first heat preservation layer 41 from spreading from the abutting positions of the second side wall 51 and the second heat preservation layer 42 to the heat preservation groove 45 and the hot rail 50 to pollute the fiber, and further avoids the pollution of the processed fiber.

[0064] In some examples, the second heat preservation layer 42 can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 (as shown in FIG. 1) or can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 and the hot rail 50 (not shown in the figure). Figure 4 Figures 8 to 10 Figure 15 In some examples, the second heat preservation layer 42 can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 (as shown in FIG. 1) or can be attached to the first heat preservation layer 41 in a manner of being wrapped around the first heat preservation layer 41 and the hot rail 50 (not shown in the figure). Figure 16 Figure 20 ​​​As shown, the first heat preservation layer 41 is configured with a protruding portion 412 protruding from the first side wall 411 and extending towards the heat preservation groove 45, and the second heat preservation layer 42 is attached to at least the first side wall 411 and can also be attached to part of the surface of the protruding portion 412 (not shown); the first fixing assembly 60 is attached to part of the surface of the protruding portion 412, extends towards the second heat preservation layer 42 and is attached to part of the surface of the second heat preservation layer 42. The first fixing assembly 60 is attached to the protruding portion 412 and the second heat preservation layer 42 at the same time, thereby synchronously limiting and fixing the first heat preservation layer 41 and the second heat preservation layer 42, which can improve the relative position stability of the first heat preservation layer 41 and the second heat preservation layer 42 in a high-temperature vibration environment, and reduce the risk of relative displacement, loosening or deviation towards the center of the heat preservation groove 45; through the wrapping type common attachment of the second heat preservation layer 42 and the first side wall 411 by the first fixing assembly 60, and the extension and attachment of the first fixing assembly 60 to the second heat preservation layer 42 to form a closed attachment area, even if debris is generated between the first heat preservation layer 41 and the second heat preservation layer 42, it will be blocked in the attachment area surrounded by the first heat preservation layer 41, the second heat preservation layer 42 and the first fixing assembly 60, avoiding the spread of debris to the heat preservation groove 45 and the hot rail 50 to cause pollution to the fiber, so as to ensure the fiber processing quality.

[0065] In some examples, the first heat preservation layer 41 is configured to be attached to at least part of the surface of the first side wall 411 of the heat preservation groove 45, and the second heat preservation layer 42 is configured to be attached to at least part of the surface of the first heat preservation layer 41. Figure 5 The first heat preservation layer 41 is configured to be attached to at least part of the surface of the first side wall 411 of the heat preservation groove 45, and the second heat preservation layer 42 is configured to be attached to at least part of the surface of the first heat preservation layer 41. Figure 6 As shown, the first fixing assembly 60 is arranged in the heat preservation groove 45 and fixed to the box body 10 at both ends along the third direction, and the first fixing assembly 60 is attached to part of the surface of the second heat preservation layer 42. The first fixing assembly 60 is fixedly connected to the box body 10 at both ends along the third direction to form a stable installation base, and then is attached to part of the surface of the second heat preservation layer 42 to limit and fix the second heat preservation layer 42, and in combination with the attachment relationship between the second heat preservation layer 42 and the first heat preservation layer 41, the relative position stability of the first heat preservation layer 41 and the second heat preservation layer 42 is maintained.

[0066] In some examples, the first heat preservation layer 41 is configured to be attached to at least part of the surface of the first side wall 411 of the heat preservation groove 45, and the second heat preservation layer 42 is configured to be attached to at least part of the surface of the first heat preservation layer 41. Figure 9 The first heat preservation layer 41 is configured to be attached to at least part of the surface of the first side wall 411 of the heat preservation groove 45, and the second heat preservation layer 42 is configured to be attached to at least part of the surface of the first heat preservation layer 41. Figure 10 As shown, the first fixing assembly 60 is arranged in the heat preservation groove 45 and fixed to the box body 10 at both ends along the third direction, and the first fixing assembly 60 is attached to part of the surface of the first heat preservation layer 41 and part of the surface of the second heat preservation layer 42. The first fixing assembly 60 is fixedly connected to the box body 10 at both ends along the third direction to form a stable installation base, and then is attached to part of the surface of the first heat preservation layer 41 and part of the surface of the second heat preservation layer 42 at the same time to limit and fix the first heat preservation layer 41 and the second heat preservation layer 42 synchronously, and in combination with the attachment relationship between the second heat preservation layer 42 and the first heat preservation layer 41, the relative position stability of the first heat preservation layer 41 and the second heat preservation layer 42 is maintained.

[0067] In some examples, the first heat preservation layer 41 is configured to be attached to at least part of the surface of the first side wall 411 of the heat preservation groove 45, and the second heat preservation layer 42 is configured to be attached to at least part of the surface of the first heat preservation layer 41. Figure 5 , Figure 6 ,Figure 9 and Figure 10 As shown, in the above embodiments, the first fixing component 60 is disposed within the insulation groove 45 and adheres to a portion of the surface of the second insulation layer 42 (or simultaneously adheres to a portion of the surface of the first insulation layer 41 and a portion of the surface of the second insulation layer 42). This ensures that the first fixing component 60 can maintain the relative position stability of the first insulation layer 41 and the second insulation layer 42, while also exposing a portion of the heat insulation surface 421 to the insulation groove 45. This ensures the limiting and fixing effect of the first fixing component 60 on the first insulation layer 41 and the second insulation layer 42, and avoids completely covering the heat insulation surface 421, which would affect the thermal barrier performance of the second insulation layer 42. It should be noted that although both ends of the first fixing component 60 are connected to the housing 10, they are separated from the front cover plate 11. This prevents heat from the insulation groove 45 from being directly conducted to the front cover plate 11 through the first fixing component 60, thereby preventing the front cover plate 11 from radiating heat dissipation and reducing heat loss inside the heat box 100 due to heat transfer.

[0068] In some examples, the parameter Figure 5 As shown, the first fixing component 60 includes at least one first fixing member 61; the first fixing member 61 is attached to a portion of the surface of the second insulation layer 42 (i.e., the heat insulation surface 421) and is separated from the front cover plate 11. The first fixing member 61 is fixedly connected to the housing 10 at both ends along a third direction to form a stable installation state, and then limits and fixes the second insulation layer 42 by attaching to a portion of the heat insulation surface 421, and combined with the attachment relationship between the second insulation layer 42 and the first insulation layer 41, it achieves the goal of maintaining the relative position stability of the first insulation layer 41 and the second insulation layer 42.

[0069] In some examples, the parameter Figure 9 As shown, the first fixing component 60 includes at least one first fixing member 61, which is attached to a portion of the surface of the first insulation layer 41 and a portion of the surface of the second insulation layer 42. The first fixing member 61 is separate from the front cover plate 11. The first fixing member 61 is fixedly connected to the housing 10 at both ends along a third direction to form a stable installation state. Then, by synchronously attaching a portion of the surface of the first insulation layer 41 to a portion of the heat insulation surface 421, the first insulation layer 41 and the second insulation layer 42 are synchronously limited and fixed. Combined with the attachment relationship between the second insulation layer 42 and the first insulation layer 41, the relative position of the first insulation layer 41 and the second insulation layer 42 is kept stable.

[0070] In some examples, the parameter Figure 6As shown, the first fixing component 60 includes a plurality of first fixing members 61; the first fixing member 61 close to the front cover plate 11 is separated from the front cover plate 11, and / or any two adjacent first fixing members 61 on the side close to the front cover plate 11 are separated. Both ends of each first fixing member 61 in the third direction are fixedly connected to the box body 10 to achieve stable installation of itself and the box body 10. Then, by fitting with a part of the heat insulation surface 421, the second heat insulation layer 42 is limited and fixed, and combined with the adhering relationship between the second heat insulation layer 42 and the first heat insulation layer 41, the relative positions of the first heat insulation layer 41 and the second heat insulation layer 42 are kept stable. Through the plurality of first fixing members 61 arranged separately on the heat insulation surface 421, the second heat insulation layer 42 is limited and fixed in a multi-point and dispersed manner, improving the uniformity of the support for the second heat insulation layer 42 and preventing the second heat insulation layer 42 from having relative displacement, loosening or shifting towards the center of the heat insulation groove 45 in a high-temperature vibration environment.

[0071] In some examples, as <0OO0203>shown, the first fixing component 60 includes a plurality of first fixing members 61; the first fixing member 61 close to the front cover plate 11 is separated from the front cover plate 11, and / or any two adjacent first fixing members 61 on the side close to the front cover plate 11 are separated. Both ends of each first fixing member 61 in the third direction are fixedly connected to the box body 10 to achieve stable installation of itself and the box body 10, and by synchronously fitting a part of the surface of the first heat insulation layer 41 and a part of the heat insulation surface 421, the first heat insulation layer 41 and the second heat insulation layer 42 are synchronously limited and fixed, and combined with the adhering relationship between the second heat insulation layer 42 and the first heat insulation layer 41, the relative positions of the first heat insulation layer 41 and the second heat insulation layer 42 are kept stable. Through the plurality of first fixing members 61 arranged separately on a part of the surface of the first heat insulation layer 41 and the heat insulation surface 421, the first heat insulation layer 41 and the second heat insulation layer 42 are limited and fixed in a multi-point and dispersed manner, improving the uniformity of the support for the first heat insulation layer 41 and the second heat insulation layer 42 and preventing the first heat insulation layer 41 and the second heat insulation layer 42 from having relative displacement, loosening or shifting towards the center of the heat insulation groove 45 in a high-temperature vibration environment. <OO00205>As Figure 6 shown, the first fixing members Figure 10 61 close to the front cover plate 11 in the above embodiments are all separated from the front cover plate 11, avoiding forming a heat conduction path from the first fixing member 61 to the front cover plate 11; or, any two adjacent first fixing members 61 on the side close to the front cover plate 11 are separated from each other. Thus, even if the first fixing member 61 close to the front cover plate 11 contacts the front cover plate 11, the heat conduction path can be blocked by the separation of any two adjacent first fixing members 61 on the side close to the front cover plate 11. Similar to the above embodiments, it is possible to prevent the heat in the heat insulation groove 45 from being conducted to the front cover plate 11 through the first fixing member 61 and then radiating heat to the outside, ensuring the heat insulation performance of the hot box 100. It should be noted thatFigure 6 and Figure 10 Only two first fasteners 61 are shown as an example. The number of first fasteners 61 can be flexibly adjusted according to the size of the second insulation layer 42 and the support strength requirements of the second insulation layer 42. The present invention does not limit this.

[0073] In some examples, the parameter Figure 19 As shown, the first fixing component 60 includes: at least one first fixing member 61 disposed in the insulation groove 45 and separated from the front cover plate 11, and an anchor 62. The first fixing member 61 is attached to a portion of the surface of the second insulation layer 42. The anchor 62 penetrates the first insulation layer 41 and the second insulation layer 42 between adjacent insulation grooves 45 along a second direction. The two ends of the anchor 62 along the penetration direction are respectively connected to two first fixing members (61', 61") arranged opposite to each other in the adjacent insulation grooves 45 to maintain the relative position of the first insulation layer 41 and the second insulation layer 42.

[0074] The anchor 62 passes through the first insulation layer 41 and the second insulation layer 42, and its two ends are respectively connected to the first fixing member 61' and the first fixing member 61" to connect the first fixing member 61' and the first fixing member 61" in series and form a bidirectional traction fixation for the first insulation layer 41 and the second insulation layer 42. It applies a uniform clamping force to the first insulation layer 41 and the second insulation layer 42 from the second direction to prevent the first insulation layer 41 and the second insulation layer 42 from relative displacement, loosening or shifting towards the center of the insulation groove 45 under high temperature vibration environment, thereby improving the long-term stability of maintaining the relative position of the first insulation layer 41 and the second insulation layer 42.

[0075] The first fastener 61 fits against a portion of the surface of the second insulation layer 42, thus limiting the second insulation layer 42 surface and providing lateral support. The anchor 62 penetrates both the first and second insulation layers 41, thus limiting their relative positions and reducing the relative displacement space along the direction of the anchor 62. Combined with the lateral support provided by the first fastener 61 to the second insulation layer 42, this further prevents the first and second insulation layers 41 from shifting towards the center of the insulation groove 45. Meanwhile, the anchor 62 connects the first insulation layer 41 and the second insulation layer 42, which makes the first insulation layer 41 and the second insulation layer 42 fit more tightly, thereby reducing the relative friction gap between the first insulation layer 41 and the second insulation layer 42, reducing the collision wear caused by vibration and impact, and thus reducing the debris generated by friction at the joint between the first insulation layer 41 and the second insulation layer 42.

[0076] In some examples, the parameter Figure 20As shown, the first fixing assembly 60 comprises at least one first fixing member 61 arranged in the heat preservation groove 45 and separated from the front cover plate 11, and an anchor 62. The first fixing member 61 is attached to part of the surface of the first heat preservation layer 41 and part of the surface of the second heat preservation layer 42. The anchor 62 penetrates the first heat preservation layer 41 between adjacent heat preservation grooves 45 in the second direction. The two ends of the anchor 62 are respectively connected to two first fixing members (61', 61'') arranged opposite to each other in the adjacent heat preservation grooves 45 in the penetrating direction, so as to maintain the relative position of the first heat preservation layer 41 and the second heat preservation layer 42. The first heat preservation layer 41 is configured with a protruding portion 412 protruding from the first side wall 411 and extending towards the heat preservation groove 45. The first fixing member 61 is attached to part of the surface of the first heat preservation layer 41 (i.e. part of the surface of the protruding portion 412) and extends towards the second heat preservation layer 42 to be attached to part of the surface of the second heat preservation layer 42, so as to achieve the attachment of the first fixing member 61 to part of the surface of the first heat preservation layer 41 and part of the surface of the second heat preservation layer 42, and to form synchronous limiting and fixing of the first heat preservation layer 41 and the second heat preservation layer 42.

[0077] The anchor 62 penetrates the first heat preservation layer 41 between adjacent heat preservation grooves 45 in the second direction and simultaneously penetrates the protruding portion 412, so that the two ends of the anchor 62 are respectively connected to the first fixing member 61' and the first fixing member 61'', so as to connect the first fixing member 61' and the first fixing member 61'' in series and form bidirectional pulling fixing of the first heat preservation layer 41 and the second heat preservation layer 42. Uniform clamping force is applied to the first heat preservation layer 41 and the second heat preservation layer 42 in the second direction, so as to prevent the first heat preservation layer 41 and the second heat preservation layer 42 from relative displacement, loosening or center deviation in the heat preservation groove 45 in a high-temperature vibration environment, and to improve the long-term stability of maintaining the relative position of the first heat preservation layer 41 and the second heat preservation layer 42.

[0078] Referring to Figure 5 , Figure 9 , Figure 19 and Figure 20 As shown, the first fixing member 61 in the above embodiment can extend towards the front cover plate 11 along the heat insulation surface 421 to form an extension 611 attached to the heat insulation surface 421. The extension 611 can increase the contact area of the first fixing member 61 and the second heat preservation layer 42, further form lateral support force on the second heat preservation layer 42, improve the stability of limiting and fixing of the second heat preservation layer 42, and prevent the second heat preservation layer 42 from collapsing or shifting due to its own material properties or in a high-temperature vibration environment.

[0079] It should be noted that the extension 611 can be a plate-like or strip-like structure (not shown) and uniformly spaced in the third direction. Alternatively, the extension 611 is an integral plate-like structure formed by continuous extension of the first fixing member 61 (as shown in the figure). Figure 5The extension 611 is separated from the front cover plate 11 to avoid forming a heat conduction path from the first fixing member 61 to the front cover plate 11, preventing heat in the heat preservation groove 45 from being conducted to the front cover plate 11 through the first fixing member 61 and then radiating to the outside, and ensuring the heat insulation performance of the box body 10.

[0080] In some examples, the first fixing assembly 60 includes at least one first fixing member 61 arranged between the first heat preservation layer 41 and the second heat preservation layer 42, and an anchor 62. The first fixing member 61 is separated from the front cover plate 11, and the first fixing member 61 is configured with a penetrating piece 612 extending into the second heat preservation layer 42. The anchor 62 penetrates the first heat preservation layer 41 between adjacent heat preservation grooves 45 in the second direction, and the two ends of the anchor 62 are respectively connected to two first fixing members (61', 61'') arranged opposite to each other in the adjacent heat preservation grooves 45. Figure 21 As shown in the drawings, the first fixing assembly 60 includes at least one first fixing member 61 arranged between the first heat preservation layer 41 and the second heat preservation layer 42, and an anchor 62. The first fixing member 61 is separated from the front cover plate 11, and the first fixing member 61 is configured with a penetrating piece 612 extending into the second heat preservation layer 42. The anchor 62 penetrates the first heat preservation layer 41 between adjacent heat preservation grooves 45 in the second direction, and the two ends of the anchor 62 are respectively connected to two first fixing members (61', 61'') arranged opposite to each other in the adjacent heat preservation grooves 45. The first fixing member 61 is arranged between the first heat preservation layer 41 and the second heat preservation layer 42, which can completely expose the heat insulation surface 421 of the second heat preservation layer 42 to the heat preservation groove 45. The first fixing member 61 is configured with a penetrating piece 612 extending into the second heat preservation layer 42, which is embedded and anchored in the second heat preservation layer 42 through the penetrating piece 612, to improve the tightness of the connection between the first fixing member 61 and the second heat preservation layer 42, and to avoid relative displacement between the first fixing member 61 and the second heat preservation layer 42 in a high-temperature vibration environment. The anchor 62 penetrates the first heat preservation layer 41 between adjacent heat preservation grooves 45 in the second direction, and the two ends of the anchor 62 are respectively connected to the first fixing member 61' and the first fixing member 61'', to connect the first fixing member 61' and the first fixing member 61'' in series and form a bidirectional pulling fixation to the first heat preservation layer 41. A uniform clamping force is applied to the first heat preservation layer 41 in the second direction, which can inhibit the thermal expansion deformation and vibration displacement of the first heat preservation layer 41 in the second direction. In combination with the tight anchoring of the penetrating piece 612 and the second heat preservation layer 42, the clamping force is transmitted to the second heat preservation layer 42, to prevent the first heat preservation layer 41 and the second heat preservation layer 42 from relative displacement, loosening or offsetting to the center of the heat preservation groove 45 in a high-temperature vibration environment, and to improve the long-term stability of the relative position between the first heat preservation layer 41 and the second heat preservation layer 42. The embedded limiting of the penetrating piece 612 and the pulling action of the anchor 62 form a synergistic effect, which can make the first heat preservation layer 41 and the second heat preservation layer 42 fit more tightly, to reduce the relative friction gap between the first heat preservation layer 41 and the second heat preservation layer 42, reduce the collision wear caused by vibration impact, and further reduce the debris generated by the friction at the junction of the first heat preservation layer 41 and the second heat preservation layer 42.

[0081] In some examples, the anchor 62 can be a sleeve-connected structure, consisting of an inner rod (not shown) and an outer tube (not shown) sleeved on the outside of the inner rod. The inner rod and the outer tube are respectively connected to the first fixing member 61' and the first fixing member 61" and are connected by plugging or snapping to fit the installation space of the box 10. The anchor 62 can also be a pin-type structure, which is a cylindrical rod (not shown) with limiting protrusions or open pin grooves at both ends. After being inserted into the first fixing member 61' and the first fixing member 61" and then prevented from detaching by limiting members (not shown), it fits the installation space of the box 10. The structure is simple and the assembly is efficient. Furthermore, the anchors 62 are configured in multiple groups and evenly distributed along the third direction to distribute the bidirectional tensile force to multiple points of the first fixing member 61' and the first fixing member 61" and to avoid the concentrated force on a single group of anchors 62, which would cause local pressure deformation or damage to the first insulation layer 41 (or the first insulation layer 41 and the second insulation layer 42). This ensures that the first insulation layer 41 and the second insulation layer 42 are subjected to balanced force as a whole, further suppressing thermal expansion deformation and vibration displacement. In some examples, the anchors 62 can also be rigid plate structures (not shown), with the entire plate being a rectangular or irregularly shaped steel plate. The two ends of the plate are integrally formed and bent to form elastic buckles (the buckle heads are provided with barbs). Corresponding to the first fixing member 61' and the first fixing member 61" are slots for matching the buckles (not shown). The middle of the plate is provided with reinforcing ribs to prevent deformation under high temperature. After the plate penetrates the first insulation layer 41 (or the first insulation layer 41 and the second insulation layer 42), the buckles at both ends are aligned with the slots of the first fixing member 61' and the first fixing member 61" and pressed down, and the barbs are inserted into the slots to achieve limiting and fixing.

[0082] It should be noted that the structure of the anchor 62 is not limited to the above-mentioned sleeve butt type, pin type and rigid plate snap type. Other connection structures can also be adopted, as long as they can achieve bidirectional traction and fixation of the first fixing parts (61', 61) in the adjacent insulation grooves 45, and are suitable for the rigidity and temperature resistance of the high temperature vibration environment of the hot box 100, and can stably maintain the relative position of the first insulation layer 41 and the second insulation layer 42, and avoid connection failure or self-deformation. The present invention does not limit the specific structural form of the anchor 62.

[0083] In some examples, the parameter Figure 21As shown, the piercing member 612' can also penetrate the second thermal insulation layer 42, and the end of the piercing member 612' penetrating out of the second thermal insulation layer 42 extends outward to form a positioning portion 6121 abutting a part of the surface of the second thermal insulation layer 42. By penetrating the second thermal insulation layer 42, the anchoring strength of the piercing member 612 and the second thermal insulation layer 42 can be further improved, and the relative displacement of the first fixing member 61 and the second thermal insulation layer 42 is further limited. In combination with the close abutment of the positioning portion 6121 and the surface of the second thermal insulation layer 42, the second thermal insulation layer 42 can be double-positioned and fixed by embedded anchoring and surface abutment, and the positioning stability is improved. At the same time, the positioning portion 6121 is still separated from the front cover plate 11, avoiding the newly formed heat conduction path from the positioning portion 6121 to the front cover plate 11, and ensuring the heat insulation performance of the box body 10.

[0084] In some examples, the user can be prompted to Figures 19 to 22 As shown, Figures 19 to 21 The anchor 62 in the second thermal insulation layer 42 can be configured as Figure 22The first anchor 621 and the second anchor 622 shown in the middle are respectively connected to two first fixing members (61', 61") in the adjacent heat preservation groove 45, and the first anchor 621 and the second anchor 622 are separated. The first anchor 621 is connected to the first fixing member 61' in the heat preservation groove 45 on one side, and the second anchor 622 is connected to the first fixing member 61" in the adjacent heat preservation groove 45. By being arranged separately, the first anchor 621 and the second anchor 622 can respectively adapt to the installation positions of the first fixing member 61' and the first fixing member 61", can adapt to the installation space limitation of the first heat preservation layer 41 and the second heat preservation layer 42, can reduce the assembly difficulty, and is convenient for subsequent maintenance and adjustment. Although the first anchor 621 and the second anchor 622 are arranged separately, they can still jointly exert a stable clamping force on the first heat preservation layer 41 by being respectively connected to the corresponding first fixing member 61' and the first fixing member 61", and can suppress the thermal expansion deformation and vibration displacement of the first heat preservation layer 41 and the second heat preservation layer 42. As an optional implementation manner, when the first fixing member (61', 61") is provided in a plurality of ways (not shown), the plurality of first fixing members (61', 61") are arranged in a separated manner on the heat insulation surface 421, and the first fixing member (61', 61") close to the front cover plate 11 is separated from the front cover plate 11, and / or any two adjacent first fixing members (61', 61") close to the side of the front cover plate 11 are separated. The anchor 62 is also provided in a plurality of ways, and the two ends of the anchor 62 are respectively connected to the first fixing member (61', 61") in the adjacent heat preservation groove 45 (or the first anchor 621 is connected to the first fixing member 61' in the heat preservation groove 45 on one side, and the second anchor 622 is connected to the first fixing member 61" in the adjacent heat preservation groove 45), so as to form multi-point dispersed limiting and fixing of the first heat preservation layer 41 and the second heat preservation layer 42, improve the uniformity of support on the first heat preservation layer 41 and the second heat preservation layer 42, and realize the relative position keeping of the first heat preservation layer 41 and the second heat preservation layer 42.

[0085] In some examples, the method includes Figure 1 The method includes Figure 2 , Figures 11 to 16As shown, the edge 111 of the front cover plate 11 near the strip-shaped opening 13 at least partially bends and extends into the heat preservation groove 45 along the surface of the second heat preservation layer 42 to form a folded edge portion 112 which is attached to part of the surface of the second heat preservation layer 42 and / or part of the surface of the first heat preservation layer 41; the first fixing assembly 60 is separated from the folded edge portion 112 to partially expose the second heat preservation layer 42. The folded edge portion 112 is attached to part of the surface of the first heat preservation layer 41 and / or part of the surface of the second heat preservation layer 42 to form lateral edge support for the first heat preservation layer 41 and / or the second heat preservation layer 42 to limit the first heat preservation layer 41 and / or the second heat preservation layer 42 from deviating towards the strip-shaped opening 13 or the center of the heat preservation groove 45. At the same time, the first fixing assembly 60 is always separated from the folded edge portion 112 to avoid forming a heat conduction path from the first fixing assembly 60 to the folded edge portion 112, thereby ensuring the heat insulation performance of the box 10.

[0086] As shown in FIGS. 1-3, Figure 1 , Figure 2 , Figure 11 , Figure 12 , Figure 15 and Figure 16 As shown in FIG. 4, the folded edge portion 112 is attached to part of the surface of the second heat preservation layer 42. Figure 13 As shown in FIG. 5, the folded edge portion 112 is attached to part of the surface of the second heat preservation layer 42 and part of the surface of the first heat preservation layer 41. Figure 14 As shown in FIG. 6, the folded edge portion 112 is attached to part of the surface of the first heat preservation layer 41. When the folded edge portion 112 is attached to part of the surface of the first heat preservation layer 41, the first fixing member 61 extends from the front cover plate 11 to the heat insulation surface 421 to form an extension portion 611 which is attached to the heat insulation surface 421 to form lateral support for the second heat preservation layer 42, thereby improving the stability of the position fixing of the second heat preservation layer 42 and preventing the second heat preservation layer 42 from collapsing or shifting due to its material properties or high-temperature vibration environment; alternatively, the first fixing members 61 are arranged separately on the heat insulation surface 421 to form multi-point dispersed position fixing for the second heat preservation layer 42, thereby improving the uniformity of the support for the second heat preservation layer 42 and preventing the second heat preservation layer 42 from collapsing or shifting due to its material properties or high-temperature vibration environment. In some examples, as shown in FIG. 7, Figure 17 As shown in FIG. 8, the folded edge portion 112 is separated from the edge 111 of the front cover plate 11. The folded edge portion 112 is fixedly connected to the box 10 at both ends in the third direction to achieve stable installation of the folded edge portion 112 to the box 10 and prevent the folded edge portion 112 from shifting or shaking, and is attached to part of the surface of the first heat preservation layer 41 and / or part of the surface of the second heat preservation layer 42 to positionally fix the first heat preservation layer 41 and / or the second heat preservation layer 42.

[0087] In some examples, as shown in FIG. 9, Figure 1 and Figure 2As shown, the inner side of the box door 20 is provided with a heat insulation structure 30 to fill part of the heat preservation groove 45 and to enclose the part of the heat preservation groove 45 containing the hot rail 50 when the strip-shaped opening 13 is closed. The heat insulation structure 30 is a flexible heat insulation structure or a rigid heat insulation structure. The heat preservation groove 45 is enclosed to form a relatively closed heat insulation space, which can block the heat inside the box body 10 from spreading to the outside, reduce heat loss, and maintain the temperature stability in the heat preservation groove 45. When the strip-shaped opening 13 is closed, the heat insulation structure 30 at least abuts against the second heat preservation layer 42 in the heat preservation groove 45, and can also simultaneously abut against the second heat preservation layer 42 and the first fixing assembly 60 to form lateral extrusion limiting of the first heat preservation layer 41 and the second heat preservation layer 42, cooperate with the first fixing assembly 60, further limit the activity space of the first heat preservation layer 41 and the second heat preservation layer 42, and prevent the first heat preservation layer 41 and the second heat preservation layer 42 from relatively displacing, loosening or offsetting to the center of the heat preservation groove 45 in a high-temperature vibration environment. The rigid heat insulation structure (not shown) is a prior art, which will not be described here, and can meet the heat insulation requirement of the enclosed heat preservation groove 45 and limit the displacement of the first heat preservation layer 41 and the second heat preservation layer 42. The flexible heat insulation structure 30 (such as Figure 1 With Figure 2 As shown) can adapt to the surface form in the heat preservation groove 45, and is more closely attached to the second heat preservation layer 42 and the first fixing assembly 60 when the box door 20 is closed, thereby improving the sealing and heat insulation effect, and extruding the second heat preservation layer 42 through flexibility to achieve more balanced lateral support effect of the first heat preservation layer 41 and the second heat preservation layer 42.

[0088] In some examples, referring to Figure 1 With Figure 2 As shown, the heat insulation structure 30 includes a fixing belt 31 detachably connected with the box door 20, an outer cladding layer 32 movably connected with the fixing belt 31 and surrounding to form an enclosed containing space 321, and a heat insulation material 33 filling the containing space 321. The fixing belt 31 is detachably connected with the box door 20, which can quickly install, replace or maintain the heat insulation structure 30 without disassembling the whole box door 20. The outer cladding layer 32 forms the enclosed containing space 321 by surrounding to ensure that the heat insulation material 33 is stably filled, and after the box door 20 is closed, the outer cladding layer 32 can closely attach to the second heat preservation layer 42 and the first fixing assembly 60 to fill the assembly gap, further improve the airtightness of the heat preservation groove 45, and improve the sealing and heat insulation effect; and the heat insulation material 33 directly blocks the high-temperature conduction to reduce the heat loss to the outside and maintain the temperature stability in the heat preservation groove 45. The whole heat insulation structure 30 after filling can form flexible extrusion limiting of the first heat preservation layer 41 and the second heat preservation layer 42 to achieve more balanced lateral support effect of the first heat preservation layer 41 and the second heat preservation layer 42. In some examples, the fixing belt 31 can be a metal material such as stainless steel. The outer cladding layer 32 can be a high-temperature resistant composite fabric such as silica gel fiberglass cloth or fluorine rubber fiberglass cloth. The heat insulation material 33 can be a high-temperature resistant fiber heat preservation material such as glass fiber cotton. Preferably, referring toFigure 1 and Figure 2 As shown, the outer layer 32 and the fixing strap 31 can be connected by straps 34. The outer layer 32 is provided with multiple adjustable straps 34. The fixing strap 31 passes through the straps 34 and is then tightened (or tightened by the elastic tension of the elastic straps 34), making operation convenient. The number of straps 34 can be one or more than two. When there is one strap 34, the length of the strap 34 along the third direction must cover the contact area between the fixing strap 31 and the outer layer 32, ensuring that the strap 34 wraps around the fixing strap 31 and is tied tightly (or the elastic strap 34 is tightened by its own tension), so as to achieve a tight fit between the fixing strap 31 and the outer layer 32. When there are two or more straps 34, the multiple straps 34 can be evenly distributed along the third direction. The spacing between adjacent straps 34 can be adjusted according to the length of the contact area between the fixing strap 31 and the outer layer 32, so as to ensure that each strap 34 can wrap around the fixing strap 31 and achieve independent tying or elastic tightening, so as to form multiple points of limit on the fixing strap 31 and tighten the fixing strap 31, preventing the outer layer 32 from shifting or loosening during the operation of the hot box 100, and ensuring the stability of the heat insulation effect.

[0089] In some examples, the parameter Figure 1 and Figure 2 As shown, the second insulation layer 42 divides the insulation groove 45 into a heating cavity 451 that houses the heat rail 50 and an insulation cavity 452 filled by the insulation structure 30. When the door 20 closes the strip opening 13, the insulation structure 30 at least abuts against a portion of the surface of the second insulation layer 42 to fill at least part of the insulation cavity 452. The insulation structure 30 can also completely fill the insulation cavity 452, or even partially penetrate the heating cavity 451. By abutting against the second insulation layer 42, or simultaneously against the second insulation layer 42 and the first fixing member 61 within the insulation groove 45, the insulation structure 30 forms a directional compression limit on the first insulation layer 41 and the second insulation layer 42. This, combined with the first fixing member 61, further reduces the movement space of the first insulation layer 41 and the second insulation layer 42, preventing them from shifting towards the center of the heating cavity 451 or experiencing relative displacement, thus improving the long-term stability of the insulation structure 40. The heat insulation structure 30 can seal the heat insulation cavity 452 and even partially penetrate the heating cavity 451 to form a more complete closed protection, further reduce the space for high temperature diffusion, reduce the conduction of high temperature from the heating cavity 451 to the outside, reduce heat loss and maintain the internal temperature of the heating cavity 451.

[0090] In some examples, the parameter Figure 18As shown, the heat preservation structure 40 further comprises: a fourth heat preservation layer 44 and a third heat preservation layer 43 arranged in the heat preservation groove 45; the fourth heat preservation layer 44 separates part of the heat preservation groove 45 to form at least two heating cavities 451 for accommodating the hot rail 50, and the third heat preservation layer 43 is at least attached to two opposite third side walls 441 of the fourth heat preservation layer 44 exposed to the heating cavities 451; the hot rail 50 comprises two second side walls 51 arranged opposite in the second direction, and the two second side walls 51 are at least respectively abutted to the third heat preservation layer 43 and the second heat preservation layer 42; the hot box 100 further comprises: a second fixing assembly 70 for maintaining the relative position of the fourth heat preservation layer 44 and the third heat preservation layer 43. The fourth heat preservation layer 44 separates the heat preservation groove 45 into at least two heating cavities 451 to achieve independent accommodation of multiple hot rails 50; the third heat preservation layer 43 is attached to the opposite third side walls 441 of the fourth heat preservation layer 44 exposed to the heating cavities 451 to form secondary heat insulation between the fourth heat preservation layer 44 and the heating cavities 451, thereby improving the overall heat insulation effect of the heat preservation groove 45. The third heat preservation layer 43 is attached to the two opposite third side walls 441 of the fourth heat preservation layer 44 or the third heat preservation layer 43 and the second fixing assembly 70 are attached to the third side walls 441 together, cooperating with the limiting action of the second fixing assembly 70 on the fourth heat preservation layer 44 and the third heat preservation layer 43, to prevent the relative displacement or deformation of the fourth heat preservation layer 44 and the third heat preservation layer 43 in a high-temperature vibration environment; at the same time, the two second side walls 51 of the hot rail 50 are respectively abutted to the third heat preservation layer 43 and the second heat preservation layer 42, forming a two-way limiting of the third heat preservation layer 43 and the second heat preservation layer 42 limiting the hot rail 50 and the hot rail 50 positioning the third heat preservation layer 43 and the second heat preservation layer 42 in reverse, to avoid the hot rail 50 from deviating and the third heat preservation layer 43 and the second heat preservation layer 42 from moving to the center of the heating cavities 451. In some examples, referring to Figure 1 With Figure 18 As shown, the hot rail 50 forms at least one wire channel 52 in the third direction, and can also be configured as two, three or four wire channels 52 arranged side by side to adapt to different fiber processing and process requirements.

[0091] In some examples, referring to Figure 18 As shown, the second fixing assembly 70 is fixed to the box body 10 at both ends in the third direction, and at least partially abuts the surface of the third heat preservation layer 43. The second fixing assembly 70 is fixedly connected to the box body 10 at both ends in the third direction to form a stable mounting state, and then abuts the surface of the third heat preservation layer 43 to limit and fix the third heat preservation layer 43, and in combination with the attachment relationship between the third heat preservation layer 43 and the fourth heat preservation layer 44, the relative position of the fourth heat preservation layer 44 and the third heat preservation layer 43 is maintained stable.

[0092] In some examples, the second fixing assembly 70 includes at least one second fixing member 71 fixedly connected to the box body 10 at both ends in the third direction, stably mounted with the box body 10, and abutting against part of the surface of the third thermal insulation layer 43 or simultaneously abutting against part of the surface of the third thermal insulation layer 43 and part of the surface of the fourth thermal insulation layer 44 to form a limiting fixation of the third thermal insulation layer 43 and realize the relative position stability of the third thermal insulation layer 43 and the fourth thermal insulation layer 44 in combination with the abutting relationship of the third thermal insulation layer 43 and the fourth thermal insulation layer 44. In some examples, as shown in Figure 18 The second fixing member 71 is separated from the hot rail 50, avoiding the formation of a heat conduction path of the second fixing member 71 and the hot rail 50, ensuring the heat insulation effect of the heating cavity 451, and avoiding vibration and collision between the second fixing member 71 and the hot rail 50 to prevent the normal work and installation stability of the hot rail 50.

[0093] In some examples, as shown in Figure 18 The second thermal insulation layer 42 and the fourth thermal insulation layer 44 jointly divide the thermal insulation groove 45 into the heat insulation cavity 452 filled by the heat insulation structure 30 and the at least two heating cavities 451 for accommodating the hot rail 50, so that when the box door 20 closes the strip-shaped opening 13, the heat insulation structure 30 at least abuts against part of the surface of the second thermal insulation layer 42 to fill at least part of the heat insulation cavity 452. The heat insulation structure 30 abuts against the second thermal insulation layer 42, or simultaneously abuts against the second thermal insulation layer 42 and the first fixing member 61 in the thermal insulation groove 45, or simultaneously abuts against the second thermal insulation layer 42, the first fixing member 61 and the second fixing member 71 in the thermal insulation groove 45, the third thermal insulation layer 43 and / or the fourth thermal insulation layer 44 to form a directional extrusion limiting of the second thermal insulation layer 42 and the first thermal insulation layer 41, further limit the activity space of the first thermal insulation layer 41 and the second thermal insulation layer 42 in cooperation with the first fixing assembly 60, limit the activity space of the third thermal insulation layer 43 and the fourth thermal insulation layer 44 in cooperation with the second fixing member 71, avoid the center deviation of the heating cavity 451 or the relative displacement of the first thermal insulation layer 41 and the second thermal insulation layer 42 or the relative displacement of the third thermal insulation layer 43 and the fourth thermal insulation layer 44, and improve the long-term stability of the thermal insulation structure 40. The heat insulation structure 30 can close the heat insulation cavity 452 (or partially intrude into the heating cavity 451), further reduce the high-temperature diffusion space, reduce the heat conduction from the heating cavity 451 to the outside, reduce the heat loss and maintain the internal temperature stability of the heating cavity 451.

[0094] In some examples, as shown in Figure 23 and Figure 24As shown, the second heat preservation layer 42 is configured to be attached to the first heat preservation part 422 of the first side wall 411, and to be abutted between the hot rail 50 and the second heat preservation part 423 of the first heat preservation part 422; the first fixing assembly 60 is at least attached to part of the surface of the second heat preservation part 423. The first fixing assembly 60 comprises the first fixing part 61 arranged in the heat preservation groove 45, which is attached to part of the surface of the second heat preservation part 423, or the first fixing part 61 is attached to part of the surface of the second heat preservation part 423 and part of the surface of the first heat preservation part 422 at the same time. The first heat preservation part 422 is attached to the first side wall 411 to form a basic heat insulation layer, and the second heat preservation part 423 fills the gap between the hot rail 50 and the first heat preservation part 422, and forms double heat preservation with the first heat preservation part 422 to improve the heat insulation effect and reduce the heat conduction to the side wall of the box body 10; when the first fixing part 61 is only attached to the second heat preservation part 423, the second heat preservation part 423 can be directionally limited, and the second heat preservation part 423 is limited from deviating to the center of the heating cavity 451 due to high temperature expansion or equipment vibration environment; when the first fixing part 61 is attached to part of the surface of the second heat preservation part 423 and part of the surface of the first heat preservation part 422 at the same time, the relative position of the first heat preservation part 422 and the second heat preservation part 423 can be maintained, the relative displacement of the first heat preservation part 422 and the second heat preservation part 423 is prevented, the hot rail 50 abuts against the second heat preservation part 423, the activity space of the first heat preservation part 422 and the second heat preservation part 423 is reduced, and the long-term stability of the heat preservation structure 40 is improved.

[0095] In some examples, the first fixing assembly 60 is at least attached to part of the surface of the second heat preservation part 423, and the first fixing part 61 can also extend along the surface of the first heat preservation part 422 to the front cover plate 11 to form a limiting part 613' (as shown in Figure 23 ), which is attached to part of the surface of the first heat preservation part 422, or the first fixing part 61 can extend along the surface of the first heat preservation part 422 to the plane where the bottom of the hot rail 50 is located to form a limiting part 613" (as shown in Figure 24 ), which is clamped by the first heat preservation part 422 and the second heat preservation part 423, so as to be attached to part of the surface of the second heat preservation part 423 and part of the surface of the first heat preservation part 422 at the same time. By means of the limiting part 613' or the limiting part 613", the contact area of the first fixing part 61 and the second heat preservation layer 42 is increased, and further support force is formed on the second heat preservation layer 42, so as to improve the stability of the limiting and fixing of the second heat preservation layer 42, and prevent the second heat preservation layer 42 from collapsing or shifting due to its own material properties or high-temperature vibration environment.

[0096] In some examples, the first thermal insulation part 422 can be a high-temperature-resistant thermal insulation material such as high-temperature-resistant glass wool, and the surface is provided with a nano reflective thermal insulation coating with a thickness of 5-10 mm, preferably 7 mm. The second thermal insulation part 423 can be a high-temperature-resistant thermal insulation material such as high-temperature-resistant ceramic plate, and at least one side surface close to the hot rail 50 is provided with a waterproof and oil-proof coating with a thickness of 10-20 mm, preferably 15 mm. The first thermal insulation layer 41 can be a high-temperature-resistant thermal insulation material such as thermal insulation rock wool.

[0097] In some examples, the piercing member 612 is a hard structure integrally formed or fixedly connected with the first fixing member 61, and is configured as a short spiral structure (not shown) to adapt to the first thermal insulation part 422. The piercing member 612 can be configured as a short spiral structure (not shown) to penetrate the high-temperature-resistant glass wool by rotating, and the spiral surface is threadedly engaged with the fibers of the high-temperature-resistant glass wool. When the device vibrates, the reverse locking force is generated by the spiral structure to prevent the relative displacement between the second thermal insulation layer 42 and the first fixing member 61. To adapt to the second thermal insulation part 423, the piercing member 612 can be configured as a hard protruding structure (not shown) with a 30-45° taper at the end, which can penetrate the waterproof and oil-proof coating and be embedded in the second thermal insulation part 423 to achieve stable anchoring through the friction between the taper and the high-temperature-resistant ceramic plate.

[0098] In some examples, the piercing member 612' extends in the direction towards the second thermal insulation layer 42 and completely penetrates the second thermal insulation layer 42, and the penetrating end (not marked) extends outward to form a positioning part 6121, and the penetrating section (not marked) can adopt a tapered or rod-shaped structure adapted to the embedded structure. The positioning part 6121 is configured as a sheet-shaped, ring-shaped or flange-shaped structure perpendicular to the penetrating section, which is attached to the thermal insulation surface 421 of the second thermal insulation layer 42 to increase the contact area with the second thermal insulation layer 42.

[0099] It should be noted that the structure of the piercing member 612 (including the piercing member 612') is not limited to the above-mentioned short spiral, 30-45° taper hard protrusion and penetrating structure with positioning function, and other connection structures can also be used, as long as they can adapt to the material properties of the first thermal insulation part 422 or the second thermal insulation part 423, effectively penetrate or embed, stably anchor the first fixing member 61 and the second thermal insulation layer 42 in a high-temperature vibration environment, prevent the relative displacement between the first fixing member 61 and the second thermal insulation layer 42, and do not affect the overall thermal insulation performance of the heat box 100. The specific structure of the piercing member 612 is not limited in the present application.

[0100] In some examples, the box door 20 further comprises a locking structure 21, which can be flexibly configured according to the specifications of the box door 20, and the number can be one or more than two. When configured as one, the locking structure 21 is assembled in the middle of the box door 20, which is suitable for small box doors 20, and when configured as two or more, it is symmetrically arranged at both ends of the box door 20 along the third direction, which is suitable for different size requirements. By applying locking force to the box door 20 through the locking structure 21, it is ensured that the box door 20 is tightly attached to the box body 10, and local warping is avoided to generate gaps; especially when symmetrically arranged at both ends, uniform locking force can be formed, so that the box door 20 is balanced, and the sealing performance and stability of the box door 20 after closing are ensured. The specific structure of the locking structure 21 is not limited in the present application.

[0101] In some examples, referring to Figure 25 With Figure 27 As shown, the first fixing member 61 is configured with a fixed part 615 extending towards the side wall of the box body 10 at both ends along the third direction, and the fixed part 615 is fastened and connected with the end part 101 of the box body 10 by a bolt (not shown). Referring to Figure 26 As shown, the second fixing member 71 is configured with a connecting part 711 extending towards the end part 101 of the box body 10 at both ends along the third direction, and the connecting part 711 is fastened and connected with the end part 101 of the box body 10 by a bolt (not shown). The fixed part 615 and the connecting part 711 are respectively flat plate structures integrally formed with the first fixing member 61 and the second fixing member 71, the extension length of the fixed part 615 and the connecting part 711 is adapted to the mounting space of the side wall of the box body 10, and the thickness of the fixed part 615 and the connecting part 711 can be set according to the fastening force requirement of the bolt to avoid deformation under its own stress. Moreover, a layer of heat insulation pad (not shown) is arranged between the fixed part 615 and the connecting part 711 and the end part 101 of the box body 10, which can cut off the heat conduction path from the first fixing member 61 and the bolt to the box body 10 and the heat conduction path from the second fixing member 71 and the bolt to the box body 10, so as to further reduce the heat loss of the heating cavity 451 through the connection node. In some examples, the first fixing member 61 is separated from the heat rail 50. The separation of the first fixing member 61 and the heat rail 50 avoids the formation of the heat conduction path from the first fixing member 61 to the heat rail 50, ensures the heat insulation effect of the heating cavity 451, and avoids the vibration and collision between the first fixing member 61 and the heat rail 50, preventing the normal work and installation stability of the heat rail 50 from being affected.

[0102] The heat box 100 of the present application can be adapted to any false twist texturing machine 1000, i.e. used as a texturing heat box of the false twist texturing machine 1000. For example, Figures 28 to 30 The heat box 100 of the present application can be adapted to any false twist texturing machine 1000, i.e. used as a texturing heat box of the false twist texturing machine 1000. For example, Figure 24For example, when the heat box 100 of the present application and the deformation heat box in the prior art are in the same working temperature (for example, the rated working temperature of about 185℃) and the same running time (for example, 2 hours) and adopt different heat preservation structures 30, different fixing assemblies 60, different front cover plates 11, different heat preservation grooves 45, and different heat insulation structures 30, the temperature detection is carried out on the heat box 100 of the present application and the deformation heat box in the prior art respectively, for example, along the directions indicated by the arrows c1, c2, c3, c4 and c5 in FIG. 6. Figure 24 The temperature detection is carried out on the five different areas of the heat box 100 of the present application in the directions indicated by the arrows c1, c2, c3, c4 and c5, and the results show that the temperatures of the areas are stably between 32.0℃ and 36.3℃, and the specific data are 36.3℃, 35.2℃, 32.0℃, 34.2℃ and 35.1℃; wherein the direction indicated by the arrow c1 corresponds to the front cover plate 11 on one side of the box door 30, the direction indicated by the arrow c2 corresponds to the side of the front cover plate 11 close to the edge of the box door 30, the direction indicated by the arrow c3 corresponds to the box door 30, the direction indicated by the arrow c4 corresponds to the other side of the front cover plate 11 close to the edge of the box door 30, and the direction indicated by the arrow c5 corresponds to the front cover plate 11 on the other side of the box door 30. The temperature detection results of the five different areas of the outer surface of the deformation heat box in the prior art show that the temperatures of the areas are between 38.2℃ and 40.1℃, and the specific data are 39.3℃, 38.6℃, 38.2℃, 38.7℃ and 40.1℃. At the same time, for example Figures 5 to 23 The heat box 100 corresponding to any of the examples can further reduce the energy consumption relative to the deformation heat box in the prior art.

[0103] The above experimental results fully prove that the heat box 100 of the present application has excellent heat blocking performance, effectively blocks the conduction of high temperature inside the heating cavity 451 to the outside, avoids the formation of large-area high-temperature radiation on the surface of the heat box 100, and at the same time, can adapt to different models of false twist texturing machines 1000 such as Figure 28 V-shaped, Figure 30 T-shaped and Figure 29 M-shaped, etc., and is used as a deformation heat box corresponding to the model, which can control the surface temperature of the box body 10 in a lower range in different model scenarios, thereby ensuring the operation safety and reducing the heat loss and energy consumption of the heat box 100 and the false twist texturing machine 1000.

[0104] It should be noted that Figures 5 to 24 the examples of the heat preservation structure 40, the fixing assembly 60, the heat preservation groove 45, the heat rail 50 and the front cover plate 11 shown in the present application can be used in combination with the open state of the box door 20 in the present application and the closed state of the box door 20 in the present application.

The yarn conveying device 200 is followed by the hot box 100, the cooling device 400, and the false twist device 300. Since the yarn conveying device 200, the cooling device 400, and the false twist device 300 are prior art, they will not be described here. The false twist texturing machine 1000 configured with the texturing hot box 100 can reduce heat loss and energy waste in practical applications, and is helpful to realize energy saving and consumption reduction. The false twist texturing machine 1000 in the embodiment can be configured as the V-shaped false twist texturing machine 1000 as shown in Figure 28 , or the M-shaped false twist texturing machine 1000 as shown in Figure 29 , or the T-shaped false twist texturing machine 1000 as shown in Figure 30 .
