Description

[0002] In the chemical fiber filament processing process, for example, the heat box carries out heating treatment to the chemical fiber such as pre-draft yarn (POY) and carries out false twist texturing to the chemical fiber after heating through subsequent conveying roller and false twist device, because the chemical fiber is decomposed under high temperature or the additive in the chemical fiber processing process volatilizes under the high temperature environment formed by the heat box, a large amount of oil fume is formed.

[0003] The prior art usually connects the exhaust pipe of the heat box with the negative pressure source, forms negative pressure in the heat box to exhaust the oil fume from the heat box. However, because the negative pressure source is difficult to completely and timely suck out the oil fume volatilized in the heat box, with the increase of use time, the oil mist contained in the oil fume is attached to the heat rail and gradually accumulates to form oil stain, because the heat box is usually installed obliquely, the oil stain on the heat rail drips from the gap between the heat rail and the door plate under the action of gravity. Especially, in order to inhibit the generation of oil stain and improve the exhaust effect of oil fume, the prior art usually needs to continuously perform the exhaust operation on the oil fume generated in the heat box or increase the suction force of the negative pressure source, but this will cause a large amount of heat loss in the heat box, resulting in excessive heat loss of the heat box and the false twist texturing machine containing the heat box, causing energy waste.

[0037] The present application will be described in detail below with reference to the embodiments shown in the drawings, but it should be noted that these embodiments are not limiting to the present application, and equivalent changes or substitutions in function, method, or structure made by those of ordinary skill in the art based on these embodiments are within the scope of the present application.

[0038] It should be noted that the drawings (for example, Figures 1 to 3 and Figures 7 to 11 ) contained in the specification of the present application are cross-sectional views or partial cross-sectional views of the hot box 100 with the flow guide structure in the Z-axis direction. Figure 1

[0039] ​During the process of performing a heating treatment on chemical fibers (e.g., pre-drawn filaments) in a hot box, the chemical fibers are thermally decomposed at high temperatures or the additives added during the chemical fiber processing volatilize in the high-temperature environment formed in the hot box, thus forming a large amount of oil fume. In the prior art, a negative pressure source is usually connected to the exhaust pipes at the upper and lower ends of the hot box, and a negative pressure is formed inside the hot box (i.e., the space area formed between the hot rail 10 and the door panel 801) to exhaust the oil fume from the hot box. However, since it is difficult for the negative pressure source to completely and timely suck out the volatilized oil fume in the hot box, as the usage time increases, the oil mist contained in the oil fume adheres to the hot rail and gradually forms oil stains. Since the hot box is usually installed obliquely on the false twist texturing machine, the hot rail is inclined with the hot box, and the oil stains on the hot rail naturally flow along the inclined direction of the hot rail under the action of gravity, converging to the bottom end of the hot rail along its length direction, resulting in the oil stains dripping from the bottom end of the hot rail through the gap between the hot rail and the door panel.

[0040] In particular, in the prior art, to suppress the generation of oil stains and improve the exhaust effect of the oil fume, it is usually necessary to continuously perform an exhaust operation on the oil fume generated in the hot box or increase the suction force of the negative pressure source, but this will cause a large amount of heat loss in the hot box, resulting in excessive heat loss in the hot box and the false twist texturing machine including the hot box, leading to energy waste.

[0041] The hot box 100 with a diversion structure in this application can be understood as the deformation hot box configured in the false twist texturing machine, or, for example, when the chemical fiber N is heated by a diphenyl heating method and applied to other types of fiber processing equipment (i.e., the superordinate concept of the false twist texturing machine), this application does not specifically limit or exclude it.

[0042] See Figure 1 And Figure 2 As shown, the hot box 100 with a diversion structure disclosed in this application (hereinafter simply referred to as "hot box 100") is used to perform a heating treatment on the chemical fiber N. At least a part of the bottom end 101 of the hot rail 10 along its length direction is constructed with an inclined guiding portion 11, and the oil stains flowing naturally along the inclined direction of the hot rail 10 converge to the inclined guiding portion 11. The oil stains flow along the inclined direction of the inclined guiding portion 11 (such as Figure 2 the direction shown by the arrow B1 in the figure), and through the bottom wall 811 abuts against the bottom end 101 of the hot rail 10 (i.e., the inclined guiding portion 11) or partially extends into the bottom end 101 of the hot rail 10, so that the oil stains converging to the bottom end 101 of the hot rail 10 can flow along the inclined guiding portion 11 towards the bottom wall 811, and the bottom wall 811 guides the oil stains into the diversion groove 810 to guide the oil stains to flow on the bottom wall 811 along the direction shown by the arrow B21 in Figure 2 the figure, thereby guiding the oil stains to flow along the bottom wall 811 to the diversion pipe 813, so that the oil stains flow in the diversion pipe 813 along the direction shown by Figure 2The oil stains flow in the direction indicated by the middle arrow B3 to be discharged from the heat box 100 through the discharge channel 814, preventing the oil stains from dripping from the bottom end of the heat rail 10 through the gap between the heat rail 10 and the door plate 801.

[0043] The heat box 100 disclosed in the present application collects the oil stains dripping from the bottom end 101 of the heat rail 10 through the flow guide structure 81 and discharges the oil stains from the heat box 100, thereby effectively avoiding the pollution of the ground by the dripping high-temperature oil drops and the personal injury of the operators in the operation channel 500 of the false twist texturing machine 1000 caused by the dripping high-temperature oil drops. The exhaust pipe (i.e., the first suction pipe 70) communicating with the flow guide pipe 813 is arranged below the heat box 100, and the first suction pipe 70 is connected to the negative pressure source. Since the flow guide structure 81 can collect the oil stains from the bottom end 101 of the heat rail 10 and discharge the oil stains from the heat box 100, the exhaust air volume required by the negative pressure source can be reduced, and the high-intensity oil fume exhaust operation does not need to be continuously performed. Even when the first suction pipe 70 is not connected to the negative pressure source, the oil stains from the bottom end 101 of the heat rail 10 can flow into the first suction pipe 70 through the flow guide structure 81 under the action of gravity and be discharged from the heat box 100, thereby reducing the heat loss in the heat box 100 caused by the oil fume exhaust operation, reducing energy waste, and achieving the purpose of energy saving and consumption reduction of the heat box 100 and the false twist texturing machine 1000 containing the heat box 100. The energy consumption to be reduced in the present application can be considered as the energy consumption produced by the heat box 100 containing the heat rail 10, or the energy consumption produced by the false twist texturing machine 1000 containing the heat box 100 as a whole, or the energy consumption produced by the false twist texturing machine 1000 and the negative pressure source together, or the energy consumption produced by the negative pressure source.

[0044] Referring to FIG. 1, the heat box 100 includes a box body 80 and a plurality of heat rails 10 arranged in the box body 80. The box body 80 is integrally formed with a flow guide structure 81 extending to the bottom end 101 of the heat rail 10 along the length direction of the heat rail 10. Figures 1 to 4 As shown in FIG. 1, the heat box 100 includes a box body 80 and a plurality of heat rails 10 arranged in the box body 80. The box body 80 is integrally formed with a flow guide structure 81 extending to the bottom end 101 of the heat rail 10 along the length direction of the heat rail 10.

[0045] During the heating process of chemical fiber N in the hot box 100, the oil on the hot rail 10 flows naturally along the inclined direction of the hot rail 10 under the action of gravity, and converges towards the bottom end 101 of the hot rail 10. The oil is then guided along the inclined guide section 11 formed at the bottom end 101 of the hot rail 10. Figure 2 The oil flows towards the bottom wall 811 in the direction indicated by the middle arrow B1. Because one end 8111 of the bottom wall 811 near the hot rail 10 abuts against the bottom end 101 of the hot rail 10 (i.e., the inclined guide portion 11) or partially extends into the bottom end 101 of the hot rail 10, the oil can flow along the inclined guide portion 11... Figure 2 The oil flows in the direction indicated by the middle arrow B21 to the bottom wall 811, enters the guide channel 810, and is then guided by the bottom wall 811 along... Figure 2 The oil flows in the direction indicated by the middle arrow B3 to the guide pipe 813, and is discharged from the hot box 100 through the discharge channel 814.

[0046] In some examples, the parameter Figure 1 As shown, the housing 80 is the outer shell of the hot box 100, used to house the hot rail 10, and the housing 80 integrally forms a flow guide structure 81 extending to the bottom end 101 of the hot rail 10. As part of the housing 80, the flow guide structure 81 guides the oil and / or fumes collected at the bottom end 101 of the hot rail 10 and discharged from the hot box 100 along the discharge channel 814, thereby reducing the retention of oil and / or fumes within the hot box 100, reducing the demand for exhaust air volume from the negative pressure source, and lowering the energy loss of the hot box 100 and the false-twist texturing machine 1000 containing the hot box 100. The synthetic fiber N forms a movement path M within the hot box 100, and is heated by the high-temperature environment within the hot box 100. Since the hot box 100 is installed at an angle on the false twisting machine 1000, the hot rail 10 is also tilted with the hot box 100. Therefore, the hot rail 10 has a certain tilt angle relative to the horizontal surface, such as 50°, 55°, 60°, etc., so that the oil can flow naturally along the tilt direction of the hot rail 10 under the action of gravity, and converge towards the bottom end 101 of the hot rail 10 (i.e., the tilted guide part 11).

[0047] In some examples, the parameter Figures 1 to 5 As shown, the discharge channel 814 is composed of a guide groove 810 and a guide pipe 813, providing a continuous and unobstructed flow path for oil and / or fumes. The bottom wall 811, which slopes downwards relative to the horizontal plane, provides the force for the oil to flow naturally to the lowest point. Under the influence of gravity, the oil flows along the inclined surface of the bottom wall 811 to the guide pipe 813, and is discharged from the heat box 100 through the discharge channel 814, preventing the oil from accumulating or leaking within the heat box 100, thus achieving smooth discharge of oil.

[0048] In some examples, the parameter Figure 2As shown, the bottom wall 811 is inclined downwards relative to the horizontal plane H. The inclination direction E of the bottom wall 811 forms an acute angle α with the horizontal plane H. By adjusting the angle α, the flow direction and velocity of the oil are adjusted. While avoiding interference between the bottom wall 811 and the movement path M of the synthetic fiber N, the larger the angle α, the stronger the component of gravity that causes the oil to flow along the bottom wall 811, thus increasing the flow velocity of the oil on the bottom wall 811 and improving discharge efficiency, while preventing the oil from stagnating and accumulating on the bottom wall 811. Preferably, the acute angle α is greater than or equal to 30° and less than or equal to 60°.

[0049] In some examples, the configuration of the bottom wall 811 abutting against the bottom end 101 of the hot rail 10 or partially extending into the bottom end 101 of the hot rail 10 can achieve the purpose of guiding the oil stains from the tilting guide 11 along... Figure 2 The flow proceeds in the direction indicated by the middle arrow B21 to the bottom wall 811. Among these, the reference... Figure 2 As shown, the bottom wall 811 abuts against the bottom end 101 of the heat rail 10, with one end 8111 directly contacting and tightly adhering to the bottom end 101 of the heat rail 10. This ensures that the oil flowing down from the heat rail 10 can be smoothly transferred to the bottom wall 811 and flow along the bottom wall 811 to the guide pipe 813 for discharge. This ensures a tight connection between the bottom wall 811 and the bottom end 101 of the heat rail 10, preventing oil leakage during the transfer process. Part of the bottom wall 811 extends into the bottom end 101 of the heat rail 10 (this state is not shown), making the joint between the bottom wall 811 and the bottom end 101 of the heat rail 10 even tighter. This reduces potential gaps and prevents oil leakage as it flows along the inclined guide portion 11 towards the bottom wall 811, reducing the risk of contamination of the external working area of ​​the heat box 100.

[0050] In some examples, the parameter Figure 2 and Figure 5 As shown, the flow guiding structure 81 further includes: a guide wall 815 inclined downward relative to the horizontal plane on the bottom wall 811 and laterally connected to the side wall 812; the guide wall 815 extends toward the hot rail 10 and partially extends past the vertical normal V of the bottom end 101 of the hot rail 10, and the guide wall 815 forms an obtuse angle β with the vertical normal V. It should be noted that the vertical normal V of the bottom end 101 of the hot rail 10 is equivalent to the vertical normal V of the bottom end 111 of the inclined guide part 11 along its inclined direction. During the process of oil flowing from the inclined guide part 11 to the bottom wall 811, the oil may drip directly downward at the connection point (not shown) between the bottom wall 811 and the bottom end 101 of the hot rail 10 due to gravity or other reasons. The guide wall 815 extends past the vertical normal V of the bottom end 101 of the hot rail 10, allowing the oil to flow along the vertical normal V of the bottom end 101 of the hot rail 10. Figure 2 As indicated by the middle arrow B22, the oil drips downwards onto the guide wall 815, then forms an obtuse angle β with the vertical normal V through the guide wall 815, allowing the oil to flow along the guide wall 815 under the influence of gravity.Figure 2 The oil flows through the guide pipe 813 in the direction indicated by the middle arrow B4, and discharges the oil from the hot box 100 through the discharge channel 814. Furthermore, during the process of guiding the oil to the guide pipe 813 via the guide wall 815, the side wall 812 can intercept the oil flowing on the guide wall 815, preventing the oil from escaping from the guide wall 815 into the guide groove 810.

[0051] In some examples, the parameter Figure 3 As shown, the sidewall 812 extends toward the heat rail 10 to abut against the bottom end 101 of the heat rail 10 or partially extends into the bottom end 101 of the heat rail 10; the flow guiding structure 81 also includes: a guide wall 815 that is inclined downward relative to the horizontal plane and disposed on the bottom wall 811 and laterally connected to the sidewall 812; the bottom wall 811, the sidewall 812 and the guide wall 815 together form a flow guiding groove 810 that connects to the flow guiding pipe 813, so as to at least discharge oil and / or fumes from the housing 80. As the oil flows from the inclined guide part 11 to the bottom wall 811, the sidewall 812 extends toward the heat rail 10 and abuts against the bottom end 101 of the heat rail 10 or partially extends into the bottom end 101 of the heat rail 10, so that the oil can also flow from the bottom end 101 of the heat rail 10 to the sidewall 812, and the bottom wall 811 and the sidewall 812 can jointly guide the oil to the flow guiding groove 810. Meanwhile, the guide wall 815 can intercept the oil stains on the side wall 812 and guide them to the guide channel 810 to prevent the oil stains from escaping from the side wall 812 and prevent the oil stains from leaking from the side wall 812 into the interior and / or exterior of the hot box 100, so that the oil stains can be discharged from the hot box 100 through the discharge channel 814.

[0052] In some examples, the parameter Figure 3 As shown, the guide wall 815 extends toward the hot rail 10 and partially extends past the vertical normal V of the bottom end 101 of the hot rail 10, forming an obtuse angle β with the vertical normal V. As oil flows from the inclined guide section 11 toward the bottom wall 811 and the side wall 812, it may drip directly downwards at the junction of the bottom wall 811 and the bottom end 101 of the hot rail 10 (not shown) due to gravity or other reasons. The oil then flows along the vertical normal V of the bottom end 101 of the hot rail 10 via the guide wall 815, allowing the oil to... Figure 3 As indicated by the middle arrow B22, the oil drips downwards onto the guide wall 815, then forms an obtuse angle β with the vertical normal V through the guide wall 815, allowing the oil to flow along the guide wall 815 under the influence of gravity. Figure 3 The oil flows through the guide pipe 813 in the direction indicated by the middle arrow B4, and discharges the oil from the hot box 100 through the discharge channel 814. Furthermore, during the process of guiding the oil to the guide pipe 813 via the guide wall 815, the side wall 812 can intercept the oil flowing on the guide wall 815, preventing the oil from escaping from the guide wall 815 into the guide groove 810.

[0053] In some examples, the parameterFigure 7 As shown, the portion of the guide wall 815 extending out of the side wall 812 and the space between the guide wall 815 and the side wall 812 are filled to form a shape as shown. Figure 7 The triangular connecting plate 816 shown is for connecting the bottom end 111 of the inclined guide portion 11 along its inclined direction. Figure 7 The oil dripping onto the guide wall 815 in the direction indicated by the middle arrow B22 is intercepted to prevent the oil from escaping from the guide wall 815 into the guide channel 810.

[0054] In some examples, the parameter Figure 2 and Figure 3 As shown, the guide pipe 813 is inclined downward relative to the horizontal plane on the bottom wall 811. The inner wall 8131 of the pipe opening at the end of the guide pipe 813 connected to the bottom wall 811 smoothly transitions to the inner wall 8151 of the guide wall 815 facing the hot rail 10. The downward inclination of the guide pipe 813 relative to the horizontal plane allows the oil in the guide groove 810 to flow more smoothly into the guide pipe 813, and the oil is then discharged from the housing 80 through the guide pipe 813, avoiding stagnation or accumulation due to oil flow resistance, thus improving oil discharge efficiency. Furthermore, the inner wall 8131 of the pipe opening connects to the inner wall 8151 of the guide wall 815 facing the hot rail 10, allowing the oil to flow smoothly from the bottom end 101 of the hot rail 10 along... Figure 2 Oil dripping onto the guide wall 815 in the direction indicated by the middle arrow B22 can flow along the inner wall 8151 to the inner wall 8131 of the pipe opening and eventually flow into the guide pipe 813, so as to avoid oil overflow or leakage.

[0055] In some examples, the parameter Figure 2 As shown, the hot box 100 also includes a first suction pipe 70 connected to the guide pipe 813. Depending on different operational requirements, the first suction pipe 70 can be connected to a negative pressure source (not shown) or not. When the first suction pipe 70 is connected to a negative pressure source (e.g., a vacuum pump), the negative pressure source generates a suction negative pressure, which draws in the oil fumes within the hot box 100 through the first suction pipe 70 and the discharge channel 814. Simultaneously, it can also collect and discharge oil stains from the guide structure 81. Under the suction force, the oil stains can be quickly discharged from the hot box 100 through the discharge channel 814 and the first suction pipe 70, improving the oil stain discharge efficiency and thus achieving the discharge of oil stains and fumes from the hot box 100. Since the guide structure 81 can collect oil stains from the bottom end 101 of the hot rail 10 and discharge them from the hot box 100, the demand for the negative pressure source's exhaust airflow can be reduced, eliminating the need for continuous high-intensity oil fume extraction operations. Even when the first suction pipe 70 is not connected to a negative pressure source, the oil stains at the bottom 101 of the hot rail 10 can flow into the first suction pipe 70 through the guide structure 81 under the action of gravity, thereby being discharged from the hot box 100. This reduces the heat loss in the hot box 100 caused by the oil fume extraction operation, reduces energy waste, and achieves the purpose of energy saving and consumption reduction in the hot box 100 and the false twisting deformation machine 1000 containing the hot box 100.

[0056] In some examples, the first suction tube 70 is integrally formed with the guide tube 813. This provides strong connection stability between the guide tube 813 and the first suction tube 70 without requiring additional fixing structures. Furthermore, it reduces the gaps formed at the joint between the first suction tube 70 and the guide tube 813, thereby lowering the risk of oil and / or fume leakage.

[0057] In some examples, the first suction tube 70 and the guide tube 813 are formed separately. This maintains the independence between the first suction tube 70 and the guide tube 813, facilitating adjustments to their configuration and position according to actual needs. For example, the length, angle, or position of the first suction tube 70 and the guide tube 813 can be adjusted according to the spatial layout. Furthermore, it facilitates independent installation, disassembly, inspection, and cleaning of the first suction tube 70 and the guide tube 813.

[0058] In some examples, the parameter Figure 1 and Figure 2 As shown, the heating box 100 also includes a second suction pipe 90 disposed on the side of the box 80 away from the airflow guiding structure 81. The first suction pipe 70 and the second suction pipe 90 form the same or different suction forces. The first suction pipe 70 and the second suction pipe 90 are connected to the same negative pressure source; or, the first suction pipe 70 and the second suction pipe 90 are connected to different negative pressure sources. In this case, the negative pressure sources to which the first suction pipe 70 and the second suction pipe 90 are respectively connected form the same or different exhaust negative pressure and suction airflow. When the first suction pipe 70 and the second suction pipe 90 are connected to the same negative pressure source, the negative pressure source only needs to provide a constant and uniform pressure to achieve the same suction force for the first suction pipe 70 and the second suction pipe 90. Furthermore, by providing a constant and uniform pressure, the negative pressure source can maintain a stable negative pressure state, thereby keeping the power consumption of the negative pressure source stable, which helps to reduce energy consumption and avoid energy consumption increases caused by power fluctuations, thus achieving higher energy efficiency.

[0059] In some examples, when the first suction pipe 70 and the second suction pipe 90 are connected to different negative pressure sources, the different negative pressure sources can still provide a constant and uniform pressure to the first suction pipe 70 and the second suction pipe 90, achieving the same suction force for both. Furthermore, the first suction pipe 70 and the second suction pipe 90 can adjust their suction forces according to their respective negative pressure sources. The power consumption of the negative pressure source will depend on the suction negative pressure and suction airflow it independently provides and generates. Each negative pressure source needs to provide different suction negative pressure and suction airflow according to the requirements of the suction pipe it is connected to (i.e., the first suction pipe 70 and the second suction pipe 90).

[0060] In some examples, the parameter Figure 1 and Figure 2As shown, the suction force formed by the second suction pipe 90 is greater than the suction force formed by the first suction pipe 70. Figure 1 As shown, a space region (not labeled) is formed between the door plate 801 and the hot rail 10, the first suction pipe 70 and the second suction pipe 90 are connected to different negative pressure sources, and the suction force of the first suction pipe 70 and the second suction pipe 90 on the space region is flexibly controlled by adjusting the pressure of the negative pressure sources, so that the suction force of the second suction pipe 90 on the space region is greater than the suction force of the first suction pipe 70 on the space region. The suction pipe opening (not shown) of the second suction pipe 90 extends into the space region at the top of the box body 80, and the high-temperature oil fume rises to the space region at the top of the box body 80, so that the second suction pipe 90 with stronger suction force can more effectively exhaust the oil fume in the hot box 100. The first suction pipe 70 with smaller suction force can make the oil fume that naturally flows to the flow guide structure 81 flow into the first suction pipe 70 through the flow guide pipe 813 and be exhausted without forcibly exhausting the oil fume, thereby reducing the heat loss in the hot box 100 caused by the oil fume exhaust operation. By providing lower suction force by the first suction pipe 70 relative to the second suction pipe 90 or not connecting the first suction pipe 70 to the negative pressure source and providing stronger suction force by the second suction pipe 90, the power output of the two negative pressure sources connected to the first suction pipe 70 and the second suction pipe 90 is matched with the required suction force, avoiding excessive suction of hot air in the space region and energy waste, thereby reducing heat loss of the hot box 100 and the false twist texturing machine 1000 containing the hot box 100, and reducing energy consumption of the hot box 100 and the false twist texturing machine 1000.

[0061] In some examples, the first suction pipe 70 and the second suction pipe 90 are connected to the same negative pressure source. Figure 4 As shown, the side wall 812 is configured with a positioning portion 8121 extending towards the hot rail 10, and the positioning portion 8121 is connected to the hot rail 10 (this state is not shown). The positioning portion 8121 provides a clear mounting position for the hot rail 10, ensures that the hot rail 10 can be fixed in the correct position, and makes the bottom wall 811 of the flow guide structure 81 abut against or partially extend into the bottom end 101 of the hot rail 10, avoiding position deviation of the hot rail 10 during installation. Moreover, the positioning portion 8121 can form a mechanical fixation with the hot rail 10, so that the flow guide structure 81 will not be displaced or loosened during operation. The positioning portion 8121 and the hot rail 10 can be connected by welding, insertion or other ways. For example, the positioning portion 8121 can be inserted into an insertion slot (not shown) configured on the hot rail 10, so that the hot rail 10 and the flow guide structure 81 maintain accurate relative positions and reduce assembly errors.

[0062] In some examples, the first suction pipe 70 and the second suction pipe 90 are connected to the same negative pressure source. Figure 6As shown, the diameter w1 of the pipe opening formed laterally at one end of the guide pipe 813 connected to the bottom wall 811 is greater than or equal to the width w2 formed laterally in the guide groove 810. This is to allow the oil to flow along the bottom wall 811. Figure 2 When the flow is in the direction indicated by the middle arrow B2, it can be completely guided into the guide pipe 813 to prevent oil from overflowing or deviating from the guide pipe 813, ensuring that the oil can be completely discharged and avoiding oil leakage into the inside or outside of the housing 80.

[0063] In some examples, the inclined guide portion 11 is formed at the bottom end 101 of the heat rail 10 along its length. Oil flowing naturally along the heat rail 10 converges to the inclined guide portion 11, with the oil flowing along the inclined direction of the inclined guide portion 11 (e.g., ...). Figure 2 The oil flows in the direction indicated by the middle arrow B1, passing through the bottom wall 811 near the hot rail 10. One end 8111 of the oil abuts against the inclined guide portion 11 or partially extends into the inclined guide portion 11, allowing the oil that converges at the bottom end 101 of the hot rail 10 to flow along the inclined guide portion 11 towards the bottom wall 811. The oil is guided into the guide channel 810 by the bottom wall 811, and the bottom wall 811 is inclined downwards relative to the horizontal surface, guiding the oil along the bottom wall 811. Figure 2 The oil flows in the direction indicated by the middle arrow B2, thereby guiding the oil sludge along the bottom wall 811 to the guide pipe 813, so that the oil sludge flows along the guide pipe 813 as shown by the middle arrow B2. Figure 2 The oil flows in the direction indicated by the middle arrow B3 to discharge the oil stains into the hot box 100 through the discharge channel 814, preventing the oil stains from dripping from the bottom of the hot rail 10 through the gap between the hot rail 10 and the door panel 801.

[0064] In some examples, the parameter Figure 8 As shown, the bottom end 101 portion of the hot rail 10 is constructed with an inclined guide portion 11a extending downward relative to the horizontal surface, or, see... Figure 9 As shown, the bottom end 101 of the hot rail 10 is constructed as an inclined guide portion 11a' extending downward relative to the horizontal surface.

[0065] In some examples, the parameter Figure 8 and Figure 9 As shown, the inclined guide section 11 extends downward at an angle relative to the horizontal plane H, forming an acute angle α1 with the horizontal plane H. By adjusting the angle α1, the flow direction and velocity of the oil are adjusted. The larger the angle α1, the stronger the component of gravity acting on the oil along the inclined guide section 11, thus making the oil flow faster on the inclined guide section 11, thereby improving the discharge efficiency and preventing the oil from stagnating and accumulating in the inclined guide section 11. Preferably, the acute angle α1 is greater than or equal to 15° and less than or equal to 75°.

[0066] In some examples, the parameter Figure 1 and Figure 6 andFigure 12 As shown, the hot rail 10 is provided with a plurality of heating channels 12 along the length direction of the hot rail 10, and a plurality of channel walls 13 formed on both sides of the heating channels 12. The inclined guide part 11 extends to the bottom end of the heating channels 12 and the channel walls 13 along the length direction of the hot rail 10. The inclined guide part 11 is provided with a flow guide part 112 extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 abuts against or partially extends into the flow guide part 112. The bottom end 121 of the heating channels 12 along the length direction of the hot rail 10 extends to the inclined guide part 11, and the bottom end 131 of the channel walls 13 along the length direction of the hot rail 10 extends to the inclined guide part 11. During the heating process of the hot box 100, the oil mist contained in the oil fume adheres to the surfaces of the channel walls 13 and the heating channels 12 and gradually forms oil stains. The oil stains on the surfaces of the channel walls 13 and the heating channels 12 naturally flow along the inclined direction of the hot rail 10 under the action of gravity, and converge to the inclined guide part 11. The oil stains flow through the flow guide part 112 to the bottom wall 811, and are discharged from the hot box 100 through the flow guide structure 81.

[0067] In some examples, the inclined guide part 11 is provided with a flow guide part 112a extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 and / or the side wall 812 abut against or partially extend into the flow guide part 112a at any position. Figure 12 The inclined guide part 11 is provided with a flow guide part 112b extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 and / or the side wall 812 abut against or partially extend into the flow guide part 112b at any position. Figure 9 As shown, the inclined guide part 11 is provided with a flow guide part 112a extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 and / or the side wall 812 abut against or partially extend into the flow guide part 112a at any position.

[0068] In some examples, the inclined guide part 11 is provided with a flow guide part 112b extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 and / or the side wall 812 abut against or partially extend into the flow guide part 112b at any position. Figure 2 As shown, the inclined guide part 11 is provided with a flow guide part 112a extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 and / or the side wall 812 abut against or partially extend into the flow guide part 112a at any position.

[0069] In some examples, the inclined guide part 11 is provided with a flow guide part 112b extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 and / or the side wall 812 abut against or partially extend into the flow guide part 112b at any position. Figure 6 As shown, to avoid the bottom wall 811 interfering with the movement path M of the fiber N, preferably, the bottom wall 811 abuts against or partially extends into the bottom end 111 of the flow guide part 112 along the inclined direction of the flow guide part 112 (i.e., the bottom end of the inclined guide part 11).

[0070] In some examples, the inclined guide part 11 is provided with a flow guide part 112b extending to the bottom end 121 of the heating channels 12, and the bottom wall 811 and / or the side wall 812 abut against or partially extend into the flow guide part 112b at any position. Figure 6 As shown, the bottom wall 811 extends along the transverse direction (i.e., the direction perpendicular to the length direction of the hot rail 10) of the hot rail 10. Figure 8The width w3 formed in the direction indicated by the X-axis is greater than the lateral width w4 between the channel walls 13 on both sides of the channel 12, so that the bottom wall 811 can fully receive the oil flowing along the inclined guide portion 11, preventing oil leakage to the inside or outside of the housing 80. In some examples, the lateral width w3 of the bottom wall 811 includes the width w2 formed laterally by the guide channel 810, so that the guide channel 810 can fully receive the oil from the bottom end 101 of the hot rail 10, preventing oil leakage to the inside or outside of the housing 80. In some examples, the overall width of the bottom wall 811 and the side wall 812 that abuts against the bottom end 101 of the hot rail 10 or partially extends into the bottom end 101 of the hot rail 10 is greater than the lateral width w4 between the channel walls 13 on both sides of the channel 12, so that the bottom wall 811 and the side wall 812 can fully receive the oil flowing from the bottom end 101 of the hot rail 10 to the bottom wall 811, preventing oil leakage to the inside or outside of the housing 80.

[0071] In some examples, the tilt guide 11 is configured as at least one of a plane or a curved surface. (See reference...) Figure 9 or Figure 10 As shown, the inclined guide section 11, when cut along the Z-axis, forms a cross-sectional shape that is a plane 11a, 11a' that is inclined downwards relative to the horizontal plane, or, refer to... Figure 11 or Figure 13 As shown, the cross-sectional shape formed by cutting the inclined guide portion 11 along the Z-axis is a curved surface 11b that curves downward relative to the horizontal surface, or even a combination of a curved surface and a plane (this state is not shown). The inclined guide portion 11 can also be other shapes that can guide oil to flow to the bottom wall 811, and this application does not limit this.
