Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a texturing heat box and a false twist texturing machine. Background Technology

[0002] A false-twist texturing machine is a chemical fiber processing device that processes pre-oriented or drawn yarns such as polyester and nylon into elastic yarns through a false-twist texturing process. Before the raw yarn enters the false-twist machine, it needs to be heated in a texturing heat box (e.g., a biphenyl heating box). Chinese utility model patent CN210657303U discloses an energy-saving heat box, including a heat rail, a box shell, and a hot water shell. A connecting block is installed on the inner side of the hot water shell, and a reflective film is provided on the side of the connecting block facing the heat rail. The reflective film fits the shape of the heat rail, and the distance between the reflective film and the heat rail is 5-12 mm. Chinese utility model patent with announcement number CN210657302U discloses an energy-saving structure for a deformable hot box, including a hot rail, a box shell, and a hot box door shell. A hot rail insulation layer is provided on both sides of the hot rail, a box shell insulation layer is provided on the box shell, and a hot box door insulation layer is provided on the hot box door shell. The heat rail insulation layers on both sides, the box shell insulation layer, and the hot box door insulation layer constitute a closed hot rail cavity.

[0003] However, in the aforementioned existing energy-saving hot box (CN210657303U), the outer shell of the box is bent to form a folded plate that extends into the hot cavity. This causes the high temperature emitted by the hot rail to be directly conducted to the surface metal plate of the outer shell of the box through the folded plate, forming a large area of ​​radiative heat dissipation. This results in heat loss inside the hot box, which not only reduces the overall energy efficiency of the hot box but also increases energy consumption. Although another energy-saving structure of deformable heat box (CN210657302U) solves the heat loss problem of existing deformable heat boxes by setting heat insulation elements on easily heat-dissipating components such as the heat rail, the outer shell of the box, and the outer shell of the heat box door, its outer shell eliminates the traditional folding plate but does not design an alternative support structure. One of the main functions of the original folding plate is to support and fix the heat insulation material inside the heat box. In the energy-saving structure of this deformable heat box, there are no positioning or support components between the heat rail insulation layer and the box insulation layer. They only rely on their connection with the heat rail, the outer shell of the box, and the outer shell of the heat box door 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 heat rail insulation layer and the box insulation layer is prone to misalignment and loosening due to vibration and impact, which will lead to friction and collision, causing the surface layer of the insulation material to fall off and generate debris. The debris may fall onto the surface of the heat rail or into the fiber channel, directly contaminating the fibers being processed inside the heat box and affecting product quality.

[0004] It should be noted that the above description of the background technology is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art.

Simultaneously, by attaching the second insulation layer to the first sidewall, even if debris is generated at the junction of the first and second insulation layers due to friction, it will be blocked by the second insulation layer within the attachment area between the first and second insulation layers, preventing debris from spreading to the insulation tank and hot rail and causing contamination of the fibers, thus ensuring the quality of fiber processing. By separating the first fixing component from the front cover plate, a metal heat conduction path from the first fixing component to the front cover plate is avoided, preventing heat inside the box from being rapidly conducted to the front cover plate through the first fixing component. This prevents the front cover plate from being heated and keeps its temperature near the ambient temperature, thereby reducing heat loss due to radiative heat dissipation, improving the energy utilization efficiency of the deformable heat box, and reducing energy consumption during the production process.

[0029] Please refer to Figures 1 to 27 The present invention discloses several specific embodiments of a deformable heat box, and the deformable heat box 100 in each embodiment of the present application is a biphenyl deformable heat box.

[0030] like Figure 1 The present invention is shown as an example of a modified hot box 100 (hereinafter referred to as "hot box 100"). The hot box 100 includes: a box body 10, and an insulation structure 40 filled inside the box body 10; the insulation structure 40 includes: a first insulation layer 41 and a second insulation layer 42, the first insulation layer 41 being configured to form an insulation groove 45 extending in a third direction, and the second insulation layer 42 being at least attached to two opposing first sidewalls 411 of the first insulation layer 41 exposed to the insulation groove 45; the box body 10 includes a front cover 11, the front cover 11 forming a strip opening 13 exposing the insulation groove 45; a door 20, pivotally connected to the front cover 11 to movably open and close the strip opening 13; a hot rail 50, two opposing second sidewalls 51 arranged in a second direction at least abutting against the second insulation layer 42; and a first fixing component 60 for maintaining the relative position of the first insulation layer 41 and the second insulation layer 42, the first fixing component 60 being separated from the front cover 11 to partially expose the second insulation layer 42.

[0031] The first insulation layer 41 forms an insulation groove 45 extending in a third direction (e.g., Figure 3 and Figure 4As shown in the diagram, the hot rail 50 is disposed within the insulation groove 45, and the second insulation layer 42 is attached to at least two first sidewalls 411 of the first insulation layer 41. The first insulation layer 41 and the second insulation layer 42 work together to form a double-layer insulation structure within the housing 10 to reduce heat loss inside the housing 10. The front cover 11 has a strip opening 13 corresponding to the insulation groove 45. The door 20 is connected to the front cover 11 via a hinge or other pivoting structure to open and close the strip opening 13. When the hot box 100 is in operation, the strip opening 13 is sealed to reduce heat leakage from the insulation groove 45 and to facilitate flexible opening during maintenance and other scenarios. The second insulation layer 42 is attached to the first sidewall 411 of the first insulation layer 41. The first fixing component 60 keeps the relative positions of the first insulation layer 41 and the second insulation layer 42 stable, preventing relative displacement, loosening, or shifting towards the center of the insulation groove 45 under high temperature of about 185°C and continuous vibration of the equipment (i.e., the false twist texturer 1000). At the same time, because the second insulation layer 42 is attached to the first sidewall 411, even if debris is generated at the junction of the first insulation layer 41 and the second insulation layer 42 due to friction, it will be blocked by the second insulation layer 42 in the attachment area between the first insulation layer 41 and the second insulation layer 42, preventing the debris from spreading to the insulation groove 45 and the hot rail 50 and causing contamination of the fibers, thus ensuring the quality of fiber processing. The two opposing second sidewalls 51 of the heat rail 50 along the second direction abut against the heat insulation surface 421 of the second insulation layer 42, thereby providing lateral support for the second insulation layer 42 and further preventing the second insulation layer 42 from shifting towards the center of the insulation groove 45. At the same time, the friction generated by the contact surface between the second insulation layer 42 and the heat rail 50 can limit the vibration amplitude of the heat rail 50, making the second insulation layer 42 and the heat rail 50 form a stable fit, further preventing the first insulation layer 41 and the second insulation layer 42 from loosening due to equipment vibration. In addition, the first fixing component 60 and the front cover plate 11 are both made of metal. If the first fixing component 60 comes into contact with the front cover plate 11, a metal heat conduction path will be formed. As the exposed outer shell of the housing 10, if the front cover plate 11 absorbs heat through the heat conduction path, it will radiate heat to the outside over a large area. This invention separates the first fixing component 60 from the front cover plate 11, avoiding the formation of a metal heat conduction path from the first fixing component 60 to the front cover plate 11. This prevents heat inside the housing 10 from being rapidly conducted to the front cover plate 11 through the first fixing component 60, thus preventing the front cover plate 11 from being heated. This reduces heat loss caused by radiative heat dissipation, thereby improving the energy utilization efficiency of the hot box 100 and reducing energy consumption during the production process.

[0032] Meanwhile, the first fixing component 60 maintains the relative position of the first insulation layer 41 and the second insulation layer 42 and is separated from the front cover plate 11, so that the second insulation layer 42 is at least partially exposed to form a heat insulation surface 421 facing the heat insulation groove 45. This ensures the stabilizing effect of the first fixing component 60 on the relative position of the first insulation layer 41 and the second insulation layer 42, and also prevents the first fixing component 60 from completely covering the heat insulation surface 421, thus preventing the thermal barrier performance of the second insulation layer 42 from being affected.

[0033] For example, the second insulation layer 42 can be attached to the two opposing first sidewalls 411 of the first insulation layer 41 exposed to the insulation groove 45 (e.g., Figure 3 (As shown); Alternatively, based on the attachment of the two first sidewalls 411, the second insulation layer 42 can extend further along the first sidewalls 411 to the space between the front cover plate 11 and the first insulation layer 41 (not shown), to further fill the gap between the front cover plate 11 and the first insulation layer 41, improving the overall sealing and insulation performance and debris interception effect; In addition, after being attached to the first sidewalls 411, the second insulation layer 42 can also extend further along the first sidewalls 411 to the space between the bottom of the heat rail 50 and the first insulation layer 41 (not shown), to limit and support the bottom of the heat rail 50, further reducing the vibration amplitude of the heat rail 50, and improving the heat insulation effect at the bottom of the insulation groove 45. Preferably, the second insulation layer 42 is only attached to the two first sidewalls 411 that are exposed to the insulation groove 45 and are arranged opposite each other, so as to achieve the insulation of the box 10 and the lateral support of the heat rail 50 with a simple structure, balancing the insulation effect and the ease of assembly of the hot box 100.

[0034] In some examples, the parameter Figure 7 and Figure 8 As shown, the second insulation layer 42 is separated from the plane where the bottom of the hot rail 50 is located. The second insulation layer 42 is attached to a portion of the second sidewall 51, and a portion of the second sidewall 51 abuts against the first insulation layer 41. The second sidewall 51 can simultaneously abut against both the first insulation layer 41 and the second insulation layer 42, and the abutting portion of the second sidewall 51 and the second insulation layer 42 is in a tight fit. This prevents cleaning fluid from seeping into the first insulation layer 41 through the gap between the second sidewall 51 and the second insulation layer 42 during subsequent cleaning and maintenance operations of the hot rail 50, thus avoiding affecting the insulation performance of the first insulation layer 41. It also prevents debris generated by the first insulation layer 41 from spreading from the abutting portion of the second sidewall 51 and the second insulation layer 42 to the insulation tank 45 and the hot rail 50, causing contamination of the fibers and thus preventing the processed fibers from being contaminated.

[0035] In some examples, the parameter Figure 4 , Figures 8 to 10 , Figure 15 and Figure 16 as well as Figure 20As shown, the first thermal insulation layer 41 is constructed with a protruding portion 412 that protrudes from the first side wall 411 and extends toward the thermal insulation groove 45. The second thermal insulation layer 42 is at least attached to the first side wall 411 and may also be attached to a partial surface of the protruding portion 412 (not shown). The first fixing component 60 is fitted to a partial surface of the protruding portion 412 and extends toward the second thermal insulation layer 42 and fits to a partial surface of the second thermal insulation layer 42. By simultaneously fitting the protruding portion 412 and the second thermal insulation layer 42, the first fixing component 60 forms a synchronous limit fixation for the first thermal insulation layer 41 and the second thermal insulation layer 42, which can improve the relative position stability of the first thermal insulation layer 41 and the second thermal insulation layer 42 in a high-temperature vibration environment and reduce the risks of relative displacement, loosening, or deviation toward the center of the thermal insulation groove 45. Through the second thermal insulation layer 42 and the first fixing component 60 forming a wrapped and co-attached structure to the first side wall 411, and the first fixing component 60 extending to fit the second thermal insulation layer 42 to form a closed attachment area, even if debris is generated between the first thermal insulation layer 41 and the second thermal insulation layer 42, it will be blocked within the attachment area surrounded by the first thermal insulation layer 41, the second thermal insulation layer 42, and the first fixing component 60, preventing the debris from spreading to the thermal insulation groove 45 and the hot rail 50 and causing contamination to the fibers, so as to ensure the fiber processing quality.

[0036] In some examples, referring Figure 5 to Figure 6 As shown, the first fixing component 60 is disposed within the thermal insulation groove 45 and fixed to the box body 10 at both ends along the third direction. The first fixing component 60 fits to a partial surface of the second thermal insulation layer 42. By fixedly connecting to the box body 10 at both ends along the third direction, the first fixing component 60 forms a stable installation foundation, and then by fitting to a partial surface of the second thermal insulation layer 42, it limits and fixes the second thermal insulation layer 42, and in combination with the attachment relationship between the second thermal insulation layer 42 and the first thermal insulation layer 41, the relative position of the first thermal insulation layer 41 and the second thermal insulation layer 42 is kept stable.

[0037] In some examples, referring Figure 9 to Figure 10 As shown, the first fixing component 60 is disposed within the thermal insulation groove 45 and fixed to the box body 10 at both ends along the third direction. The first fixing component 60 fits to a partial surface of the first thermal insulation layer 41 and a partial surface of the second thermal insulation layer 42. By fixedly connecting to the box body 10 at both ends along the third direction, the first fixing component 60 forms a stable installation foundation, and then by simultaneously fitting to a partial surface of the first thermal insulation layer 41 and a partial surface of the second thermal insulation layer 42, it forms a synchronous limit fixation for the first thermal insulation layer 41 and the second thermal insulation layer 42, and in combination with the attachment relationship between the second thermal insulation layer 42 and the first thermal insulation layer 41, the relative position of the first thermal insulation layer 41 and the second thermal insulation layer 42 is kept stable.

[0038] Referring Figure 5 to Figure 6 toFigure 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.

[0039] 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.

[0040] 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.

[0041] 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. Combining with the attachment relationship between the second heat insulation layer 42 and the first heat insulation layer 41, the relative position between the first heat insulation layer 41 and the second heat insulation layer 42 is kept stable. The plurality of first fixing members 61 are arranged in a separated manner on the heat insulation surface 421 to form multi-point dispersed limit fixing for the second heat insulation layer 42, improve the uniformity of the support for the second heat insulation layer 42, and prevent 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.

[0042] In some examples, referring to Figure 10 As 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, synchronous limit fixing for the first heat insulation layer 41 and the second heat insulation layer 42 is formed. Combining with the attachment relationship between the second heat insulation layer 42 and the first heat insulation layer 41, the relative position between the first heat insulation layer 41 and the second heat insulation layer 42 is kept stable. The plurality of first fixing members 61 are arranged in a separated manner on a part of the surface of the first heat insulation layer 41 and the heat insulation surface 421 to form multi-point dispersed limit fixing for the first heat insulation layer 41 and the second heat insulation layer 42, improve the uniformity of the support for the first heat insulation layer 41 and the second heat insulation layer 42, and prevent 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.

[0043] Referring to Figure 6 With Figure 10 As shown, the first fixing members 61 close to the front cover plate 11 in the above embodiments are all 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; 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, heat in the heat insulation groove 45 can be prevented from being conducted to the front cover plate 11 through the first fixing member 61 and then radiated 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In some examples, the parameter Figure 20As shown, the first fixing component 60 includes: at least one first fixing member 61 disposed in the heat preservation tank 45 and separated from the front cover plate 11, and an anchor 62; the first fixing member 61 is fitted to a partial surface of the first heat preservation layer 41 and a partial surface of the second heat preservation layer 42, the anchor 62 penetrates the first heat preservation layer 41 between adjacent heat preservation tanks 45 in the second direction, and both ends of the anchor 62 in the penetration direction are respectively connected to two first fixing members (61', 61") disposed oppositely in adjacent heat preservation tanks 45 to maintain the relative positions of the first heat preservation layer 41 and the second heat preservation layer 42. A protruding portion 412 protruding from the first side wall 411 and extending toward the heat preservation tank 45 is formed on the first heat preservation layer 41, the first fixing member 61 is fitted to a partial surface of the first heat preservation layer 41 (i.e., a partial surface of the protruding portion 412), and extends toward the second heat preservation layer 42 to be fitted to a partial surface of the second heat preservation layer 42, so as to realize that the partial surface of the first fixing member 61 fitted to the first heat preservation layer 41 and the partial surface of the second heat preservation layer 42 synchronously limit and fix the first heat preservation layer 41 and the second heat preservation layer 42.

[0048] The anchor 62 penetrates the first heat preservation layer 41 between adjacent heat preservation tanks 45 in the second direction and synchronously penetrates the protruding portion 412, so that both 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 two-way pulling and fixing of the first heat preservation layer 41 and the second heat preservation layer 42, and apply a uniform clamping force to the first heat preservation layer 41 and the second heat preservation layer 42 from the second direction to prevent the first heat preservation layer 41 and the second heat preservation layer 42 from having relative displacement, loosening or shifting toward the center of the heat preservation tank 45 in a high-temperature vibration environment, and improve the long-term stability of maintaining the relative positions of the first heat preservation layer 41 and the second heat preservation layer 42.

[0049] Refer to Figure 5 , Figure 9 , Figure 19 and Figure 20 As shown, the first fixing member 61 in the above-mentioned embodiment can extend along the heat insulation surface 421 toward the front cover plate 11 to form an extension portion 611 that fits the heat insulation surface 421. The extension portion 611 can increase the contact area between the first fixing member 61 and the second heat preservation layer 42, further form a lateral supporting force on the second heat preservation layer 42, improve the stability of limiting and fixing the second heat preservation layer 42, and prevent the second heat preservation layer 42 from collapsing and shifting due to its own material properties or in a high-temperature vibration environment.

[0050] It should be noted that the extension portion 611 can be in a plate-like or strip-like structure (not shown) and multiple are uniformly distributed at intervals in the third direction; or, the extension portion 611 is an integral plate-like structure formed by continuous extension of the first fixing member 61 (such as Figure 5(As shown). Regardless of which form is adopted, the extension 611 must be separated from the front cover 11 to avoid forming a heat conduction path from the first fixing member 61 to the front cover 11, and to prevent heat in the insulation groove 45 from being conducted to the front cover 11 through the first fixing member 61 and then radiating heat to the outside, thus ensuring the heat insulation performance of the box 10.

[0051] In some examples, the parameter Figure 21 As shown, the first fixing component 60 includes: at least one first fixing member 61 disposed between the first insulation layer 41 and the second insulation layer 42, and an anchor 62; the first fixing member 61 is separate from the front cover plate 11, the first fixing member 61 is configured with an insert 612 extending at least into the second insulation layer 42, the anchor 62 penetrates the first insulation layer 41 between adjacent insulation grooves 45 along a second direction, and the two ends of the anchor 62 along the penetration direction are respectively connected to two opposing first fixing members (61', 61") disposed in adjacent insulation grooves 45. The fastener 61 is disposed between the first insulation layer 41 and the second insulation layer 42, allowing the heat-insulating surface 421 of the second insulation layer 42 to be fully exposed to the insulation groove 45. The first fastener 61 is also constructed with an insert 612 extending at least into the second insulation layer 42. The insert 612 is embedded and anchored within the second insulation layer 42 to improve the tightness of the connection between the first fastener 61 and the second insulation layer 42, thus preventing relative displacement between the first fastener 61 and the second insulation layer 42 under high-temperature vibration conditions. The anchor 62 penetrates the adjacent insulation groove 45 along the second direction. The first insulation layer 41 between 5 is connected to the first fixing member 61' and the first fixing member 61" at both ends, so that the first fixing member 61' and the first fixing member 61" are connected in series and form a bidirectional traction fixation for the first insulation layer 41. A uniform clamping force is applied to the first insulation layer 41 from the second direction, which can suppress the thermal expansion deformation and vibration displacement of the first insulation layer 41 along the second direction; at the same time, with the tight anchoring of the insert 612 and the second insulation layer 42, the clamping force is transferred to the second insulation layer 42 to prevent the first insulation layer 41 and the second insulation layer 42 from being in contact. Under high-temperature vibration, relative displacement, loosening, or shifting towards the center of the insulation groove 45 may occur, improving the long-term stability of maintaining the relative position of the first insulation layer 41 and the second insulation layer 42. The embedded limiting of the insert 612 and the pulling action of the anchor 62 work together to make 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 collision wear caused by vibration and impact, and thus reducing debris generated by friction at the joint of the first insulation layer 41 and the second insulation layer 42.

[0052] 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.

[0053] 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.

[0054] In some examples, the parameter Figure 21As shown, the insert 612' can also penetrate the second insulation layer 42, and one end of the insert 612' extending outward from the second insulation layer 42 forms a positioning part 6121 that fits against a portion of the surface of the second insulation layer 42. By having the insert 612 penetrate the second insulation layer 42, the anchoring strength between the insert 612 and the second insulation layer 42 can be further improved, further limiting the relative displacement between the first fixing member 61 and the second insulation layer 42. Combined with the tight fit between the positioning part 6121 and the surface of the second insulation layer 42, a dual limiting fixation of embedded anchoring and surface fitting can be formed for the second insulation layer 42, improving positioning stability. At the same time, the positioning part 6121 remains separate from the front cover plate 11, avoiding the formation of a new heat conduction path from the positioning part 6121 to the front cover plate 11, ensuring the thermal insulation performance of the enclosure 10.

[0055] In some examples, the parameter Figures 19 to 22 As shown, Figures 19 to 21 The anchor 62 in the middle can be configured as follows Figure 22The first anchor 621 and the second anchor 622 shown are respectively connected to two first fixing members (61', 61) in adjacent insulation grooves 45. The first anchor 621 and the second anchor 622 are separate. The first anchor 621 is connected to the first fixing member 61' in one side of the insulation groove 45, and the second anchor 622 is connected to the first fixing member 61" in the adjacent insulation groove 45. By separating the first anchor 621 and the second anchor 622, the installation positions of the first fixing members 61' and 61" can be adapted respectively, which can adapt to the installation space limitations of the first insulation layer 41 and the second insulation layer 42, reduce the assembly difficulty, and facilitate subsequent maintenance and adjustment. Although the first anchor 621 and the second anchor 622 are separated, they can still apply a stable clamping force to the first insulation layer 41 by connecting the corresponding first fixing members 61' and 61" respectively, suppressing the thermal expansion deformation and vibration displacement of the first insulation layer 41 and the second insulation layer 42. As an optional implementation, when multiple first fasteners (61', 61") are provided (not shown), the multiple first fasteners (61', 61") are arranged separately on the heat insulation surface 421, and the first fasteners (61', 61") near the front cover plate 11 are separated from the front cover plate 11, and / or, any two adjacent first fasteners (61', 61") on the side near the front cover plate 11 are separated. Multiple anchors 62 are also provided, and both ends of the anchors 62 are respectively connected to the first fixing members (61', 61”) in the adjacent insulation groove 45 (or the first anchor 621 is connected to the first fixing member 61' in one side of the insulation groove 45, and the second anchor 622 is connected to the first fixing member 61” in the adjacent insulation groove 45), so as to form a multi-point dispersed limiting fixation for the first insulation layer 41 and the second insulation layer 42, improve the uniformity of support for the first insulation layer 41 and the second insulation layer 42, so as to maintain the relative position of the first insulation layer 41 and the second insulation layer 42.

[0056] In some examples, the parameter Figure 1 and Figure 2 , Figures 11 to 16As shown, the edge 111 of the front cover plate 11 close to the strip-shaped opening 13 is at least partially bent and extended along the surface of the second thermal insulation layer 42 into the thermal insulation groove 45 to form a hemmed portion 112 that fits against a partial surface of the second thermal insulation layer 42 and / or a partial surface of the first thermal insulation layer 41; the first fixing assembly 60 is separated from the hemmed portion 112 to partially expose the second thermal insulation layer 42. The hemmed portion 112 forms a lateral edge support for the first thermal insulation layer 41 and / or the second thermal insulation layer 42 by fitting against a partial surface of the first thermal insulation layer 41 and / or a partial surface of the second thermal insulation layer 42, so as to limit the first thermal insulation layer 41 and / or the second thermal insulation layer 42 from shifting towards the strip-shaped opening 13 or towards the center of the thermal insulation groove 45. At the same time, the first fixing assembly 60 is always separated from the hemmed portion 112 to avoid forming a heat conduction path from the first fixing assembly 60 to the hemmed portion 112 and ensure the heat insulation performance of the box body 10.

[0057] As shown in Figure 1 , Figure 2 , Figure 11 , Figure 12 , Figure 15 and Figure 16 shown, the hemmed portion 112 only fits against a partial surface of the second thermal insulation layer 42; as shown in Figure 13 , the hemmed portion 112 fits against a partial surface of the second thermal insulation layer 42 and a partial surface of the first thermal insulation layer 41 at the same time; as shown in Figure 14 , the hemmed portion 112 only fits against a partial surface of the first thermal insulation layer 41. When the hemmed portion 112 only fits against a partial surface of the first thermal insulation layer 41, the first fixing member 61 extends along the heat insulation surface 421 towards the front cover plate 11 to form an extended portion 611 that fits against the heat insulation surface 421, so as to form a lateral supporting force on the second thermal insulation layer 42 and improve the stability of the limit fixing of the second thermal insulation layer 42, preventing the second thermal insulation layer 42 from collapsing or shifting due to its own material properties or high-temperature vibration environment; alternatively, by arranging multiple first fixing members 61 separately on the heat insulation surface 421, a multi-point dispersed limit fixing is formed for the second thermal insulation layer 42 to improve the uniformity of the support for the second thermal insulation layer 42 and prevent the second thermal insulation layer 42 from collapsing or shifting due to its own material properties or high-temperature vibration environment. In some examples, as shown in Figure 17 , the hemmed portion 112 is separated from the edge 111 of the front cover plate 11. Both ends of the hemmed portion 112 in the third direction are fixedly connected to the box body 10 to achieve stable installation of itself and the box body 10, avoid displacement or shaking of the hemmed portion 112, and limit and fix the first thermal insulation layer 41 and / or the second thermal insulation layer 42 by fitting against a partial surface of the first thermal insulation layer 41 and / or a partial surface of the second thermal insulation layer 42.

[0058] In some examples, as shown in Figure 1 and Figure 2As shown, the inner side of the door 20 is provided with a heat insulation structure 30, which fills part of the heat insulation groove 45 when the strip opening 13 is closed, and seals the perimeter of the heat insulation groove 45 that houses the heat rail 50. The heat insulation structure 30 can be a flexible or rigid heat insulation structure. After the heat insulation groove 45 is sealed, a relatively closed heat insulation space is formed, which can prevent the heat inside the box 10 from spreading to the outside, reduce heat loss, and maintain a stable temperature inside the heat insulation groove 45. When the strip opening 13 is closed, the heat insulation structure 30 at least abuts against the second heat insulation layer 42 inside the heat insulation groove 45, and can also abut against the second heat insulation layer 42 and the first fixing component 60 at the same time, so as to form a lateral compression limit on the first heat insulation layer 41 and the second heat insulation layer 42. In conjunction with the first fixing component 60, it further restricts the movement space of the first heat insulation layer 41 and the second heat insulation layer 42, preventing the first heat insulation layer 41 and the second heat insulation layer 42 from relative displacement, loosening, or shifting towards the center of the heat insulation groove 45 under high temperature vibration environment. Rigid insulation structures (not shown) are existing technology and will not be described in detail here. They only need to meet the insulation requirements after the insulation groove 45 is closed, while limiting the displacement of the first insulation layer 41 and the second insulation layer 42. Flexible insulation structures 30 (such as...) Figure 1 and Figure 2 As shown, it can adapt to the surface morphology inside the insulation groove 45, and when the box door 20 is closed, it fits more tightly with the second insulation layer 42 and the first fixing component 60, improving the sealing and heat insulation effect. It also achieves a more balanced lateral support effect for the first insulation layer 41 and the second insulation layer 42 by flexibly squeezing the second insulation layer 42.

[0059] In some examples, the parameter Figure 1 and Figure 2 As shown, the thermal insulation structure 30 includes: a fixing strap 31 detachably connected to the door 20; an outer cladding layer 32 movably connected to the fixing strap 31 and forming a receiving space 321; and thermal insulation material 33 filling the receiving space 321. The fixing strap 31 is detachably connected to the door 20, allowing for quick installation, replacement, or maintenance of the thermal insulation structure 30 without disassembling the entire door 20. The outer cladding layer 32, by forming a closed receiving space 321, ensures stable filling of the thermal insulation material 33. After the door 20 is closed, it tightly adheres to the second insulation layer 42 and the first fixing component 60 to fill assembly gaps, further improving the airtightness of the insulation groove 45 and enhancing the sealing and thermal insulation effect. Furthermore, the thermal insulation material 33 directly blocks high-temperature conduction, reducing heat loss to the outside and maintaining a stable temperature inside the insulation groove 45. The completed insulation structure 30 provides flexible compression and restraint for the first insulation layer 41 and the second insulation layer 42, achieving a more balanced lateral support effect. In some examples, the fixing strap 31 can be made of metal materials such as stainless steel. The outer layer 32 can be a high-temperature resistant composite fabric such as silicone fiberglass cloth or fluoropolymer fiberglass cloth. The insulation material 33 can be a high-temperature resistant fiber insulation material such as glass fiber cotton. Preferably, the following...Figure 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.

[0060] 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.

[0061] In some examples, the parameter Figure 18As shown, the insulation structure 40 further includes: a fourth insulation layer 44 and a third insulation layer 43 disposed in the insulation groove 45; the fourth insulation layer 44 divides part of the insulation groove 45 to form at least two heating chambers 451 for accommodating the heat rail 50, and the third insulation layer 43 is at least attached to two third sidewalls 441 of the fourth insulation layer 44 exposed to the heating chambers 451 and disposed opposite to each other; the heat rail 50 includes two second sidewalls 51 disposed opposite to each other along a second direction, and the two second sidewalls 51 respectively at least abut against the third insulation layer 43 and the second insulation layer 42; the heat box 100 further includes: a second fixing component 70 for maintaining the relative positions of the fourth insulation layer 44 and the third insulation layer 43. The fourth insulation layer 44 divides the insulation groove 45 into at least two heating chambers 451 to achieve independent accommodation of multiple heat rails 50; the third insulation layer 43 is attached to the fourth insulation layer 44 and exposed to the opposite third sidewall 441 of the heating chamber 451 to form secondary insulation between the fourth insulation layer 44 and the heating chamber 451, thereby improving the overall insulation effect of the insulation groove 45. The third insulation layer 43 is attached to the two opposite third sidewalls 441 of the fourth insulation layer 44, or the third insulation layer 43 and the second fixing component 70 are jointly attached to the third sidewalls 441. Together with the second fixing component 70, this limits the relative displacement or deformation of the fourth insulation layer 44 and the third insulation layer 43 under high-temperature vibration conditions. Simultaneously, the two second sidewalls 51 of the heat rail 50 respectively abut against the third insulation layer 43 and the second insulation layer 42, forming a bidirectional limiting mechanism where the third insulation layer 43 and the second insulation layer 42 limit the heat rail 50, and the heat rail 50 reverses the positioning of the third insulation layer 43 and the second insulation layer 42, preventing the heat rail 50 from shifting and the third insulation layer 43 and the second insulation layer 42 from moving towards the center of the heating cavity 451. In some examples, [the following text is incomplete and requires further context to translate accurately]. Figure 1 and Figure 18 As shown, the hot rail 50 forms at least one filament path 52 along a third direction, and can also be configured as two, three or four filament paths 52 arranged in parallel to adapt to different fiber processing and process requirements.

[0062] In some examples, the parameter Figure 18 As shown, the second fixing component 70 is fixed to the housing 10 at both ends along the third direction, and the second fixing component 70 is at least in contact with a portion of the surface of the third insulation layer 43. The second fixing component 70 is fixedly connected to the housing 10 at both ends along the third direction to form a stable installation state, and then limits and fixes the third insulation layer 43 by contacting a portion of the surface of the third insulation layer 43. Combined with the attachment relationship between the third insulation layer 43 and the fourth insulation layer 44, the relative position of the fourth insulation layer 44 and the third insulation layer 43 is kept stable.

[0063] In some examples, the second fixing component 70 includes at least one second fixing member 71, which is fixedly connected to the housing 10 at both ends along a third direction, stably installed with the housing 10, and forms a limiting fixation on the third insulation layer 43 by adhering to a portion of the surface of the third insulation layer 43 or simultaneously adhering to a portion of the surface of the third insulation layer 43 and a portion of the surface of the fourth insulation layer 44. Combined with the adhesion relationship between the third insulation layer 43 and the fourth insulation layer 44, it achieves the stability of the relative position of the third insulation layer 43 and the fourth insulation layer 44. In some examples, the reference... Figure 18 As shown, the second fixing member 71 is separated from the hot rail 50. Separating the second fixing member 71 from the hot rail 50 avoids the formation of a heat conduction path between the second fixing member 71 and the hot rail 50, ensuring the heat insulation effect of the heating cavity 451, and preventing vibration and collision between the second fixing member 71 and the hot rail 50, thus preventing any impact on the normal operation and installation stability of the hot rail 50.

[0064] In some examples, the parameter Figure 18 As shown, the second insulation layer 42 and the fourth insulation layer 44 together divide the insulation groove 45 into an insulation cavity 452 filled by the insulation structure 30 and at least two heating cavities 451 for accommodating the heat rail 50; so that when the box 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 a portion of the insulation cavity 452. The heat insulation structure 30 abuts against the second insulation layer 42, or simultaneously abuts against the second insulation layer 42 and the first fixing member 61 in the insulation groove 45, or simultaneously abuts against the second insulation layer 42 and the first fixing member 61 and the second fixing member 71 in the insulation groove 45, as well as the third insulation layer 43 and / or the fourth insulation layer 44, to form a directional compression limit on the second insulation layer 42 and the first insulation layer 41. In conjunction with the first fixing component 60, it further restricts the movement space of the first insulation layer 41 and the second insulation layer 42, and in conjunction with the second fixing member 71, it restricts the movement space of the third insulation layer 43 and the fourth insulation layer 44, so as to avoid displacement towards the center of the heating cavity 451 or relative displacement between the first insulation layer 41 and the second insulation layer 42 or between the third insulation layer 43 and the fourth insulation layer 44, thereby improving the long-term stability of the heat insulation structure 40. The heat insulation structure 30 can seal the heat insulation cavity 452 (or partially invade the heating cavity 451), further reducing the high temperature diffusion space, reducing the heat conduction from the heating cavity 451 to the outside, reducing heat loss and maintaining the internal temperature of the heating cavity 451.

[0065] In some examples, the parameter Figure 23 and Figure 24As shown, the second insulation layer 42 is configured to be attached to the first insulation portion 422 of the first sidewall 411, and to be held between the heat rail 50 and the first insulation portion 422; the first fixing component 60 is at least attached to a portion of the surface of the second insulation portion 423. The first fixing component 60 includes a first fixing member 61 disposed in the insulation groove 45 that is attached to a portion of the surface of the second insulation portion 423, or the first fixing member 61 is attached to both a portion of the surface of the second insulation portion 423 and a portion of the surface of the first insulation portion 422. The first insulation part 422 is attached to the first side wall 411 to form a basic heat insulation layer. The second insulation part 423 fills the gap between the heat rail 50 and the first insulation part 422, forming a double insulation with the first insulation part 422 to improve the heat barrier effect and reduce the heat conduction to the side wall of the box 10. When the first fixing member 61 is only attached to the second insulation part 423, it can form a directional limit on the second insulation part 423, limiting the second insulation part 423 from shifting towards the center of the heating cavity 451 due to high temperature expansion or equipment vibration. When the first fixing member 61 is attached to part of the surface of the second insulation part 423 and part of the surface of the first insulation part 422 at the same time, it can maintain the relative position of the first insulation part 422 and the second insulation part 423, preventing relative displacement between the first insulation part 422 and the second insulation part 423. In conjunction with the heat rail 50, it supports the second insulation part 423, reduces the activity space of the first insulation part 422 and the second insulation part 423, and improves the long-term stability of the insulation structure 40.

[0066] In some examples, the first fixing component 60 is at least attached to a portion of the surface of the second insulation portion 423, and the first fixing member 61 may also extend along the surface of the first insulation portion 422 to the front cover plate 11, forming a limiting portion 613' that is attached to a portion of the surface of the first insulation portion 422 (e.g., Figure 23 (As shown), or, the first fixing member 61 may extend along the surface of the first heat insulation part 422 toward the plane where the bottom of the heat rail 50 is located, forming a limiting part 613 that is clamped by the first heat insulation part 422 and the second heat insulation part 423 (as shown). Figure 24 As shown), this allows for simultaneous contact between a portion of the surface of the second insulation part 423 and a portion of the surface of the first insulation part 422. The limiting part 613' or "limiting part 613" increases the contact area between the first fixing member 61 and the second insulation layer 42, further supporting the second insulation layer 42, improving the stability of the limiting and fixing of the second insulation layer 42, and preventing the second insulation layer 42 from collapsing or shifting due to its own material properties or under high-temperature vibration conditions.

[0067] In some examples, the first insulation part 422 can be a high-temperature resistant insulation material such as high-temperature resistant fiberglass wool, and its surface is provided with a nano-reflective heat-insulating coating with a thickness of 5-10 mm, preferably 7 mm. The second insulation part 423 can be a high-temperature resistant insulation material such as high-temperature resistant ceramic plate, and its surface, at least on the side closest 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 insulation layer 41 can be a high-temperature resistant insulation material such as insulating rock wool.

[0068] In some examples, the insert 612 is an integrally formed or fixedly connected rigid structure of the first fixing member 61. To adapt to the first insulation part 422, the insert 612 can be constructed as a short spiral structure (not shown). By rotating and inserting into the high-temperature resistant fiberglass cotton, the spiral surface forms a threaded engagement with the fibers of the high-temperature resistant fiberglass cotton. When the equipment vibrates, the spiral structure generates a reverse locking force to prevent relative displacement between the second insulation layer 42 and the first fixing member 61. To adapt to the second insulation part 423, the insert 612 can be constructed as a rigid protrusion structure with a 30-45° taper at the end (not shown). It can penetrate the waterproof and oil-proof coating and, after being embedded in the second insulation part 423, achieves stable anchoring through the friction between the conical surface and the high-temperature resistant ceramic plate.

[0069] In some examples, the insert 612' extends in the direction toward the second insulation layer 42 and completely penetrates the second insulation layer 42. The penetrating end (not shown) extends outward to form a positioning part 6121. The penetrating section (not shown) may adopt a conical or rod-shaped structure adapted to the embedded structure. The positioning part 6121 is configured as a sheet-like, annular, or folded structure perpendicular to the penetrating section and fits against the heat insulation surface 421 of the second insulation layer 42 to increase the contact area with the second insulation layer 42.

[0070] It should be noted that the structure of the insert 612 (including insert 612') is not limited to the above-mentioned short spiral, 30-45° tapered hard protrusion and through-type positioning structure. Other connection structures can also be used, as long as they can be adapted to the material properties of the first insulation part 422 or the second insulation part 423, achieve effective insertion or embedding, and firmly anchor the first fixing part 61 and the second insulation layer 42 under high temperature vibration environment to prevent relative displacement between the first fixing part 61 and the second insulation layer 42, and do not affect the overall heat insulation performance of the heat box 100. The present invention does not limit the specific structural form of the insert 612.

[0071] In some examples, the door 20 also includes a locking structure 21, which can be flexibly configured according to the specifications of the door 20, and the number can be one or more. When configured as one, the locking structure 21 is assembled in the middle of the door 20, suitable for small doors 20. When configured as two or more, it is symmetrically arranged at both ends of the door 20 along a third direction to accommodate different size requirements. The locking structure 21 applies a locking force to the door 20, ensuring that the door 20 fits tightly with the box body 10 and avoiding gaps caused by local warping; especially when symmetrically arranged at both ends, it can form a uniform locking force, making the door 20 subjected to balanced force, ensuring the sealing and stability of the door 20 after it is closed. The present invention does not limit the specific structure of the locking structure 21.

[0072] In some examples, the parameter Figure 25 and Figure 27 As shown, the first fastener 61 has a fixing portion 615 extending from its two ends along a third direction, bending towards the side wall of the housing 10. The fixing portion 615 is fastened to the end 101 of the housing 10 using bolts (not shown). (See reference...) Figure 26 As shown, the second fixing member 71 has connecting portions 711 that bend and extend towards the end 101 of the housing 10 at both ends along a third direction. The connecting portions 711 are fastened to the end 101 of the housing 10 using bolts (not shown). The fixing portion 615 and the connecting portion 711 are flat structures integrally formed by the first fixing member 61 and the second fixing member 71, respectively. The extension length of the fixing portion 615 and the connecting portion 711 is adapted to the installation space of the side wall of the housing 10. The thickness of the fixing portion 615 and the connecting portion 711 can be set according to the bolt tightening force requirements to avoid deformation under stress. Furthermore, a heat insulation pad (not shown) is sandwiched between the fixing portion 615 and the end 101 of the housing 10 where they are connected to the housing 10. This cuts off the heat conduction path from the first fixing member 61 and the bolt to the housing 10, as well as the heat conduction path from the second fixing member 71 and the bolt to the housing 10, to further reduce the heat loss from the heating chamber 451 through the connection nodes. In some examples, the first fastener 61 is separated from the heating rail 50. Separating the first fastener 61 from the heating rail 50 avoids the formation of a heat conduction path between the first fastener 61 and the heating rail 50, ensuring the heat insulation effect of the heating cavity 451, and preventing vibration and collision between the first fastener 61 and the heating rail 50, thus preventing any impact on the normal operation and installation stability of the heating rail 50.

[0073] The heating box 100 of this invention can be adapted to, for example Figures 28 to 30 Any of the false twist texturing machines 1000 can be used as the texturing heat box for the false twist texturing machine 1000. Figure 24For example, when the hot box 100 of the present invention and the deformable hot box in the prior art are at the same operating temperature (e.g., approximately 185°C, rated operating temperature) and the same operating time (e.g., 2 hours), and under the conditions of using different insulation structures 30, different fixing components 60, different front cover plates 11, different insulation grooves 45, and different heat insulation structures 30, the temperature of the hot box 100 of the present invention and the deformable hot box in the prior art are respectively measured. For example, along... Figure 24 The directions indicated by the middle arrows c1, c2, c3, c4, and c5 represent the temperature measurements of five different areas of the hot box 100 of the present invention. The results show that the temperature of each area is stable between 32.0℃ and 36.3℃, specifically 36.3℃, 35.2℃, 32.0℃, 34.2℃, and 35.1℃. Among them, the direction indicated by arrow c1 corresponds to the front cover 11 on one side of the door 30, the direction indicated by arrow c2 corresponds to the side of the front cover 11 near the edge of the door 30, the direction indicated by arrow c3 corresponds to the door 30, the direction indicated by arrow c4 corresponds to the other side of the front cover 11 near the edge of the door 30, and the direction indicated by arrow c5 corresponds to the front cover 11 on the other side of the door 30. Temperature measurements of five different areas on the outer surface of the existing deformable heat chamber showed that the temperatures in each area ranged from 38.2℃ to 40.1℃, specifically 39.3℃, 38.6℃, 38.2℃, 38.7℃, and 40.1℃. Meanwhile, for example... Figures 5 to 23 The heat box 100 corresponding to any instance can further reduce energy consumption compared to the deformable heat box in the prior art.

[0074] The above experimental results fully demonstrate that the heating box 100 of the present invention possesses excellent thermal insulation performance, effectively blocking the conduction of high temperature inside the heating chamber 451 to the outside, and avoiding the formation of large-area high-temperature radiation on the surface of the heating box 100. At the same time, it can be adapted to... Figure 28 Medium V-shape Figure 30 T-shaped and Figure 29 The false twist texturing machine 1000 of different models such as the M-type is used as the texturing heat box of the corresponding model. Under different model scenarios, it can control the temperature of the outer surface of the box 10 to a low range, which not only ensures operational safety, but also reduces heat loss and lowers the energy consumption of the heat box 100 and the false twist texturing machine 1000.

[0075] It should be noted that, Figures 5 to 24 The examples of the insulation structure 40, fixing component 60, insulation groove 45, heat rail 50, and front cover plate 11 shown can all be used with Figure 1 The middle box door 20 is open and Figure 2 The middle box door 20 is used in combination when closed.

[0076] Based on the same inventive concept, this embodiment also discloses a false-twist texturing machine 1000, see reference. Figures 28 to 30As shown, the false-twist texturing machine 1000 includes: a yarn conveying device 200, a cooling device 400, a false-twist device 300, and a texturing heat box 100 disposed between the yarn conveying device 200 and the cooling device 400. Following the yarn conveying device 200 are the heat 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 in detail here. This false-twist texturing machine 1000, with the texturing heat box 100 configured, can reduce heat loss and energy waste in practical applications, contributing to energy conservation and consumption reduction. The false-twist texturing machine 1000 in this embodiment can be configured as follows... Figure 28 The V-type false twist texturing machine 1000 shown, or as... Figure 29 The M-type false twist texturing machine 1000 shown, or Figure 30 The T-type false-twist texturing machine 1000 shown in this embodiment. The specific technical solution of the texturing heat box 100 included in the false-twist texturing machine 1000 in this embodiment can be found in any of the foregoing embodiments or any combination of several embodiments, and will not be repeated here.

[0077] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
