Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a deformation heating box and a stretching deformation device. Background Technology

[0002] A false-twist texturing machine is a textile machine that processes pre-oriented or fully drawn yarns such as polyester and nylon into elastic yarns of different varieties and finenesses through false twisting. The biphenyl heating chamber is a commonly used heating component in false-twist texturing machines. The biphenyl heating chamber typically consists of a heating chamber shell filled with insulation material to reduce heat loss. A heating rail is installed in the channels formed by the insulation material, and the yarn passes over the heating rail and is heated. Biphenyl, as a highly efficient heat transfer medium, primarily functions to transfer heat to the heating rail, thereby evenly distributing heat to the yarn passing through the heating chamber. Furthermore, a hot spot is installed on the top of the heating chamber shell for easy maintenance and inspection.

[0003] Chinese utility model patent with announcement number CN210657303U discloses an energy-saving hot box, including a hot rail, a box shell, and a hot water shell. A connecting block is installed on the inside of the hot water shell. A reflective film is provided on the side of the connecting block facing the hot rail. The reflective film fits the shape of the hot rail, and the distance between the reflective film and the hot rail is 5-12mm.

[0004] However, in the aforementioned prior art, the outer shell of the hot box is bent to form a folded plate extending into the hot cavity. This causes the heat emitted by the hot rail to be conducted to the outer shell of the box through the folded plate, resulting in a large area of ​​heat dissipation through the surface of the outer shell of the box, causing heat loss. This not only reduces the overall energy efficiency of the hot box but also increases energy consumption.

[0005] In view of this, it is necessary to improve the existing energy-saving heating boxes to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to disclose a deformable heat box and a stretching deformation device, which can solve many defects of the existing energy-saving heat boxes, especially to block the path of heat conduction through the folding plate to the outer shell of the operating surface, reduce the heat conducted by the folding plate to the outer shell of the operating surface, and reduce the heat loss of the box.

[0007] To achieve the above objectives, in a first aspect, the present invention provides a deformable hot box, comprising: a box body having a strip-shaped opening, a hot spot disposed in the strip-shaped opening, a first insulating material built into the box body and forming a channel, and a hot rail disposed in the channel;

[0008] The enclosure includes: an operating surface shell extending toward and opposite to the strip opening, and a folded plate connecting the operating surface shell and abutting the first insulation material; the first heat insulation layer is sandwiched at the connection between the folded plate and the operating surface shell.

[0009] As a further improvement of the present invention, the folding plate includes a connecting portion connected to the operating surface shell, the connecting portion extending toward the first thermal insulation material to form a transition portion, and the transition portion extending to form a joint portion pressing against the first thermal insulation material.

[0010] As a further improvement of the present invention, a reflector is provided on the side of the hot spot facing the hot rail, and a second heat insulation layer is clamped at the connection between the reflector and the hot spot.

[0011] As a further improvement of the present invention, the reflector includes: a reflective portion formed on the joint portion opposite to the side of the hot rail, the reflective portion having a mirror-like surface on one side surface facing the hot rail, and the reflective portion extending towards the end of the transition portion to form a connecting portion for connecting the hot rail.

[0012] As a further improvement of the present invention, the inner wall of the side of the hot spot facing the reflective part is configured as a third inner wall, and a third heat insulation layer is attached to the third inner wall.

[0013] As a further improvement of the present invention, the inner wall of the side of the hot spot facing the reflective part is configured as a third inner wall, and the third inner wall is filled with a second thermal insulation material between the reflective part and the connecting part.

[0014] As a further improvement of the present invention, the third heat insulation layer extends along the third inner wall and connects to the second heat insulation layer.

[0015] As a further improvement of the present invention, the hot spot is rotatably connected to the housing and rotates about a hinge axis to open or close the strip opening;

[0016] The second heat insulation layer, located near the hinge axis, extends toward the first heat insulation material and is bent to form a heat insulation connection segment connecting the first heat insulation layer.

[0017] When the strip opening is opened, the thermal insulation connection section switches from an unstretched state to a stretched state; when the strip opening is closed, the thermal insulation connection section switches from a stretched state to an unstretched state.

[0018] As a further improvement of the present invention, the hot spot is rotatably connected to the housing and rotates about a hinge axis to open or close the strip opening;

[0019] A second heat insulation layer on the side away from the hinge axis extends toward the first heat insulation material to form a first mating end, and the first heat insulation layer is configured to have a second mating end that engages with the first mating end;

[0020] When the strip opening is opened, the first mating end and the second mating end separate; when the strip opening is closed, the first mating end and the second mating end engage.

[0021] As a further improvement of the present invention, the joint extends toward the hot rail to form a limiting portion that contacts or separates from the first thermal insulation material.

[0022] In a second aspect, the present invention also provides a stretching and deformation device, comprising: a yarn conveying device, a cooling device, a false twisting device, and a deformation heat box as described in any one of the first aspects.

[0023] Compared with the prior art, the beneficial effects of the present invention are: by setting a first heat insulation layer at the connection between the folding plate and the operating surface shell, the path of heat conduction through the folding plate to the operating surface shell is blocked, effectively reducing the heat conducted by the folding plate to the operating surface shell, significantly reducing the heat dissipation of the operating surface shell surface, thereby reducing the heat loss of the box, so that the deformable heat box can significantly reduce energy consumption and improve energy utilization efficiency in practical applications.

[0033] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. All equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 9 A specific embodiment of a deformation heat box and a tensile deformation device is disclosed.

[0035] See Figures 1 to 4 As shown, in this embodiment, the deformable hot box 100 includes: a box body 1 having a strip-shaped opening 10, a hot spot 2 disposed in the strip-shaped opening 10, a first heat insulation material 3 built into the box body 1 and forming a channel 31, and a heat rail 4 disposed in the channel 31; the box body 1 includes: an operating surface shell 11 extending toward the strip-shaped opening 10 and disposed opposite to it, and a folding plate 13 connecting the operating surface shell 11 and abutting against the first heat insulation material 3; a first heat insulation layer 51 is clamped at the connection between the folding plate 13 and the operating surface shell 11.

[0036] In this embodiment, the heat exchanger 2, the folding plate 13, the operating surface shell 11, and the first insulation material 3 together form a heat cavity 101. The heat emitted by the heat rail 4 is concentrated in the heat cavity 101. The first insulation material 3 and the first insulation layer 51 effectively isolate the heat in the heat cavity 101, allowing the heat in the heat cavity 101 to be evenly transferred to the yarn, thereby improving the heating effect on the yarn. The folding plate 13 holds the first insulation material 3 to fix it inside the housing 1, preventing the first insulation material 3 from shifting or falling off during use, and preventing heat leakage from the connection between the folding plate 13 and the first insulation material 3, thereby reducing heat loss. Preferably, the first insulation layer 51 is made of a material with low thermal conductivity, such as aerogel or nano-insulation board.

[0037] In existing technologies, the bending of the outer shell of the enclosure to form a folded plate extending into the heat cavity causes heat to be conducted to the surface of the outer shell through the folded plate, resulting in large-area heat dissipation and heat loss. This application addresses this by providing a first heat insulation layer 51 at the connection between the folded plate 13 and the operating surface outer shell 11, thereby blocking the path of heat conduction from the folded plate 13 to the operating surface outer shell 11. This effectively reduces the heat conducted from the folded plate 13 to the operating surface outer shell 11, significantly reducing heat dissipation from the surface of the operating surface outer shell 11, and thus reducing heat loss from the enclosure 1. This allows the deformable heat box 100 to significantly reduce energy consumption and improve energy efficiency in practical applications.

[0038] A typical false-twist texturing system (not shown) includes 15 mirror-arranged texturing machines (not shown), employing a total of 30 texturing heat chambers, with 6 heating rails within each heat chamber. Experiments have shown that, under the same test conditions (e.g., the same room temperature, a set heating temperature of 200°C for the texturing heat chamber, and a working time of 24 hours), a comparative test was conducted between existing texturing heat chambers and the texturing heat chamber 100 of this application. The temperature at each measuring point on one side of the hot spot in the existing texturing heat chamber was 51°C to 58°C, while the temperature at each measuring point on one side of the hot spot in the texturing heat chamber 100 of this application was 40°C to 44°C. Compared to existing texturing heat chambers, the texturing heat chamber 100 of this application can save approximately 3 kWh of energy every 24 hours under the same conditions, resulting in a total energy saving of 90 kWh for all 30 heat chambers. Therefore, it is evident that the total energy saving increases significantly with the increase in the number of texturing heat chambers 100. Thus, in large-scale applications, the deformable heat box 100 of this application can significantly reduce energy consumption, which helps to achieve energy conservation and emission reduction, and the saved electricity can reduce operating costs.

[0039] See Figure 1 and Figure 3 and Figure 4As shown, in this embodiment, the housing 1 is constructed with a plurality of spaced-apart strip openings 10, each strip opening 10 being equipped with a hotspot 2. The operating surface housing 11 includes a first shell plate 111 and a second shell plate 112 formed on both sides of the hotspot 2, the first shell plate 111 and the second shell plate 112 extending toward the strip openings 10 and being disposed opposite to each other. The folding plate 13 includes a first folding plate 131 and a second folding plate 132. The first folding plate 131 and the second folding plate 132 are respectively connected to the first shell plate 111 and the second shell plate 112. The first heat insulation layer 51a is clamped at the connection between the first folding plate 131 and the first shell plate 111, and the first heat insulation layer 51b is clamped at the connection between the second folding plate 132 and the second shell plate 112. The first shell plate 111, as part of the sidewall of the housing 1, extends toward the strip opening 10 and is connected to the first folding plate 131. The second shell plate 112, as another part of the sidewall of the housing, extends toward the strip opening 10 and is connected to the second folding plate 132. By clamping the first heat insulation layer 51a at the connection between the first folding plate 131 and the first shell plate 111, and clamping the first heat insulation layer 51b at the connection between the second folding plate 132 and the second shell plate 112, the path of heat conduction through the first folding plate 131 to the first shell plate 111 and the path of heat conduction through the second folding plate 132 to the second shell plate 112 are effectively blocked. This effectively reduces the heat of the first shell plate 111 and the second shell plate 112, and significantly reduces the heat dissipation from the surfaces of the first shell plate 111 and the second shell plate 112, thereby reducing the heat loss of the box 1. This allows the deformable heat box 100 to significantly reduce energy consumption and improve energy utilization efficiency in practical applications.

[0040] See Figure 3 and Figure 8 As shown, in this embodiment, preferably, the side of the heating rail 4 is clamped by the channel 31 to fix the position of the heating rail 4 inside the housing 1, preventing the heating rail 4 from shifting or loosening due to external vibration or other factors during use. This also ensures that the contact area between the heating rail 4 and the first insulation material 3 is maximized, which helps to improve the insulation effect of the heating rail 4, further reduces heat loss, and improves the uniformity of heat transfer from the heating rail 4 to the yarn, ensuring that heat can be evenly transferred from the heating rail 4 to the yarn, thus improving the heating effect.

[0041] See Figure 4As shown, in this embodiment, the folding plate 13 includes a connecting portion 133 connected to the operating surface shell 11. The connecting portion 133 extends toward the first insulation material 3 to form a transition portion 134, and the transition portion 134 extends to form a joint portion 135 that presses against the first insulation material 3. The connecting portion 133 is connected to the operating surface shell 11 to ensure a firm connection between the folding plate 13 and the housing 1. The first heat insulation layer 51 is sandwiched between the connecting portion 133 and the operating surface shell 11. The first heat insulation layer 51 blocks the path of heat conduction from the connecting portion 133 to the operating surface shell 11, thereby effectively reducing the heat of the operating surface shell 11 and significantly reducing the heat dissipation from the surface of the operating surface shell 11, thus reducing the heat loss of the housing 1. The connecting portion 133 is connected to the joint portion 135 through the transition portion 134, which provides a certain supporting function to ensure that the first insulation material 3 will not shift due to gravity or external force. Furthermore, the joint 135 ensures close contact between the folded plate 13 and the first insulation material 3, preventing heat loss through the gap between the folded plate 13 and the first insulation material 3, thus improving the heat insulation effect.

[0042] See Figure 4 As shown, in this embodiment, a reflector 24 is disposed on the side of the hot spot 2 facing the hot rail 4, and a second heat insulation layer 52 is clamped at the connection between the reflector 24 and the hot spot 2. It should be noted that the reflector 24 is constructed as a metal shell with a mirror-like outer surface, such as stainless steel or chrome-plated / nickel-plated metal shell; in this embodiment, stainless steel is preferred. The mirror-like outer surface of the reflector 24 can reflect most of the heat back to the hot rail 4, reducing heat loss. By reflecting heat, the reflector 24 ensures that heat is better concentrated around the hot rail 4, thereby improving heating efficiency and the overall energy efficiency of the deformation heating box 100. Furthermore, the reflection of heat by the reflector 24 helps improve the temperature uniformity around the hot rail 4, ensuring the consistency of the yarn during the heating process. The second heat insulation layer 52 effectively blocks the path of heat conduction from the reflector 24 to the hot spot 2, effectively reducing the heat of the hot spot 2, thereby reducing heat dissipation from the surface of the hot spot 2, reducing heat loss from the box 1, and further reducing energy consumption.

[0043] See Figure 4As shown, in this embodiment, the reflector 24 includes a reflective portion 241 formed on the side of the joint 135 opposite to the heat rail 4. A mirror surface 2411 is formed on the surface of the reflective portion 241 facing the heat rail 4. The end of the reflective portion 241 extending towards the transition portion 134 forms a connecting portion for connecting the hot spot 2. The connecting portion connects the hot spot 2, ensuring a secure connection between the reflector 24 and the hot spot 2. The reflective portion 241 is located on the side of the joint 135 opposite to the heat rail 4, and the mirror surface 2411 faces the heat rail 4. The mirror surface 2411 reflects heat back to the heat rail 4, ensuring that heat is better concentrated around the heat rail 4 and improving heating efficiency. The connecting portion includes a first connecting portion 242 and a second connecting portion 243. The first connecting part 242 and the second connecting part 243 connect the first inner wall 21 and the second inner wall 22 of the hotspot 2, respectively. A second heat insulation layer 52a is sandwiched between the first connecting part 242 and the first inner wall 21, and a second heat insulation layer 52b is sandwiched between the second connecting part 243 and the second inner wall 22. The second heat insulation layers 52a and 52b block the path of heat conduction to the hotspot 2 through the first connecting part 242 and the second connecting part 243, effectively reducing the heat of the hotspot 2, thereby reducing the heat dissipation from the surface of the hotspot 2, reducing the heat loss of the housing 1, and further reducing energy consumption.

[0044] See Figure 4 As shown, in this embodiment, preferably, the inner wall of the side of the hotspot 2 facing the reflective part 241 is configured as a third inner wall 23, and a third heat insulation layer 53 is attached to the third inner wall 23. The third heat insulation layer 53, attached to the third inner wall 23, reduces heat transfer from the third inner wall 23 to the outer surface of the hotspot 2, and reduces heat dissipation from the outer surface of the hotspot 2, thereby reducing heat loss. The first connecting part 242 and the second connecting part 243 can be inserted into or abut against the third heat insulation layer 53 but do not contact the third inner wall 23. By preventing the first connecting part 242 and the second connecting part 243 from directly contacting the third inner wall 23, the thermal bridging effect between the first connecting part 242 and the second connecting part 243 is reduced, further reducing the possibility of heat being conducted to the outer surface of the hotspot 2 through the connecting parts.

[0045] See Figure 5 As shown, exemplarily, in some embodiments, the inner wall of the side of the hotspot 2 facing the reflective part 241 is configured as a third inner wall 23, and a second thermal insulation material 6 is filled between the third inner wall 23, the reflective part 241, and the connecting part. The second thermal insulation material 6, filled between the third inner wall 23 and the reflective part 241 and the connecting part, reduces the transfer of heat from the third inner wall 23 to the outer surface of the hotspot 2, reduces the dissipation of heat from the outer surface of the hotspot 2, and thus reduces heat loss.

[0046] See Figure 7As shown, exemplarily, in some embodiments, the third heat insulation layer 53 extends along the third inner wall 23 and connects to the second heat insulation layer 52. The two ends of the third heat insulation layer 53 extend along the third inner wall 23 and connect to the second heat insulation layer 52a and the second heat insulation layer 52b, respectively. The connection between the third heat insulation layer 53 and the second heat insulation layer 52 forms an integral heat insulation structure, effectively reducing heat transfer from the third inner wall 23 to the outer surface of the hotspot 2, reducing heat dissipation from the outer surface of the hotspot 2, and thus reducing heat loss.

[0047] See Figure 6 As shown, exemplarily, in some embodiments, the heat exchanger 2 is rotatably connected to the housing 1 and rotates about a hinge axis A to open or close the strip opening 10; the second insulation layer 52 near the hinge axis A extends toward the first insulation material 3 and is bent to form an insulation connection segment 521 connecting the first insulation layer; when the strip opening 10 is opened, the insulation connection segment 521 switches from an unstretched state to a stretched state, and when the strip opening 10 is closed, the insulation connection segment 521 switches from a stretched state to an unstretched state. The heat exchanger 2 is connected to the housing 1 via a rotating structure such as a hinge 25 or a pivot (not shown). For example, see [link to hinge 25 example]. Figure 6 As shown, hinge axis A serves as the rotation axis of hinge 25. The second insulation layer 52b extends toward the first insulation material 3 and is bent to form an insulation connection section 521 connecting the first insulation layer 51b. Hot spot 2 rotates around hinge axis A and along... Figure 6 When rotated in the direction indicated by the middle arrow a1, the strip opening 10 is opened, and the heat-insulating connecting section 521 switches from an unstretched state to a stretched state. The heat-insulating connecting section 521 reduces heat loss from the connection between the hot spot 2 and the housing 1, thus reducing heat loss. When the hot spot 2 rotates around the hinge axis A in the opposite direction to arrow a1, the strip opening 10 is closed, and the heat-insulating connecting section 521 switches from a stretched state to an unstretched state. This ensures the sealing of the strip opening 10, improves the heating efficiency inside the deformable heat box 100, and prevents heat loss through the connection between the second heat insulation layer 52b and the first heat insulation layer 51b, ensuring the heat insulation effect on the heat cavity 101.

[0048] See Figure 6As shown, exemplarily, in some embodiments, the hotspot 2 is rotatably connected to the housing 1 and rotates about a hinge axis A to open or close the strip opening 10; a second heat insulation layer 52 on the side away from the hinge axis A extends toward the first heat insulation material 3 to form a first mating end 522, and the first heat insulation layer is configured to have a second mating end 511 that engages with the first mating end 522; when the strip opening 10 is opened, the first mating end 522 separates from the second mating end 511, and when the strip opening 10 is closed, the first mating end 522 engages with the second mating end 511. The hotspot 2 is connected to the housing 1 by a rotating structure such as a hinge 25 or a pivot (not shown). For example, see [link to hinge 25]. Figure 6 As shown, hinge axis A serves as the rotation axis of hinge 25. The second insulation layer 52a extends toward the first insulation material 3 to form a first mating end 522, and the first insulation layer 51a is constructed to form a second mating end 511 that engages with the first mating end 522. Hot spot 2 rotates around hinge axis A and along... Figure 6 When rotated in the direction indicated by arrow a1, the strip opening 10 is opened, and the first mating end 522 separates from the second mating end 511. When the hot spot 2 rotates around the hinge axis A in the opposite direction to arrow a1, the strip opening 10 is closed, and the first mating end 522 and the second mating end 511 are tightly engaged to ensure the sealing of the strip opening 10 and improve the heating efficiency inside the deformable heat box 100. Furthermore, when the strip opening 10 is closed, there are no obvious gaps or cracks between the second insulation layer 52a and the first insulation layer 51a, preventing heat loss through the connection between the second insulation layer 52a and the first insulation layer 51a, thus ensuring the insulation effect on the heat cavity 101.

[0049] See Figure 4 As shown, in this embodiment, preferably, the joint portion 135 extends towards the heat rail 4 to form a limiting portion 136 that contacts the first insulation material 3. When the limiting portion 136 contacts the first insulation material 3, the joint portion 135 and the limiting portion 136 can jointly abut against the top inner corner 32 of the first insulation material 3, thereby ensuring a tight fit between the joint portion 135 and the insulation material and reducing heat loss through the gap between the joint portion 135 and the corner 32 of the limiting portion 136. This also ensures that the joint portion 135 is accurately positioned when in contact with the first insulation material 3, preventing displacement or loosening of the joint portion 135 during use. The limiting portion 136 provides support for the joint portion 135 in the direction towards the heat rail 4, enhancing structural stability. Exemplarily, in some embodiments, the limiting portion 136 is separated from the first insulation material 3.

[0050] See Figure 8As shown, the deformation heating box 100 also includes a biphenyl heating mechanism for heating the heating rail 4. The biphenyl heating mechanism includes a liquid-holding pipe 71, a heating pipe 72, a condenser pipe 73, and an air inlet pipe 74, all disposed within the box body 1. The two ends of the heating rail 4 are connected to the liquid-holding pipe 71 and the condenser pipe 73 respectively via the heating pipe 72 and the air inlet pipe 74. A return pipe 75 is provided between the liquid-holding pipe and the condenser pipe. When the deformation heating box 100 is in operation, the heating rod 76 in the liquid-holding pipe 71 heats the biphenyl within the liquid-holding pipe 71. As the heating temperature rises, the liquid biphenyl transforms into vaporized biphenyl. The vaporized biphenyl enters the heating rail 4 through the heating pipe 72, causing the temperature of the heating rail 4 to rise, thereby heating the high-speed moving yarn as it passes through the heating rail 4. Simultaneously, the vaporized biphenyl cools and gathers in the condenser pipe 73, then returns to the liquid-holding pipe 71 via the return pipe 75, thus achieving biphenyl circulation.
