[0030] The utility model will be explained in detail in combination with the embodiments shown in the drawings, but it should be explained that these embodiments are not the limitation of the utility model, the equivalent transformation or substitution of function, method or structure made by the ordinary skilled in the art according to these embodiments all belong to the protection scope of the utility model.

[0031] It should be noted that the drawings (for example, Figures 2 to 9 ) contained in the specification of the present application are all Figure 7 The sectional view or partial sectional view formed by cutting the hot box 100 along the Z-axis in the drawings.

[0032] In the process of the hot box performing heating treatment on the chemical fiber (for example, pre-drafting yarn), the chemical fiber is decomposed at high temperature or the additives added in the chemical fiber processing process volatilize in the high-temperature environment formed by the hot box, thereby forming a large amount of oil fume. In the prior art, a negative pressure source is usually connected to the smoke exhaust pipes at the upper and lower ends of the hot box, and negative pressure is formed in the hot box (i.e., the space region formed between the hot rail 10 and the door plate 801) to exhaust the oil fume from the hot box. However, since the negative pressure source is difficult to completely and timely suck out the volatilized oil fume in the hot box, with the increase of the use time, the oil mist contained in the oil fume is attached to the hot rail and gradually accumulates to form oil stains. Since the hot box is usually installed obliquely in 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, converge to the bottom end of the hot rail along the length direction of the hot rail, and cause the oil stains to drip from the bottom end of the hot rail through the gap between the hot rail and the door plate, thereby causing pollution to the ground of the working area, and even the high-temperature oil drops may cause personal injury to the operator in the operation channel of the false twist texturing machine.

[0033] The hot box 100 in the present application can be understood as a texturing hot box configured in the false twist texturing machine, or, for example, the chemical fiber N is heated and treated by adopting the biphenyl heating mode and applied to other types of fiber processing equipment (i.e., the upper concept of the false twist texturing machine), and the present application is not specifically limited and excluded.

[0034] The heat rails 10 disclosed in the present application are arranged in the heat box 100 to uniformly transfer heat energy to the surface of the chemical fiber N. The bottom end 111 of the rail body 11 is at least partially configured with a guide portion 14. The oil stains on the groove 13 and the groove wall 12 naturally flow along the inclined direction of the heat rail 10 to converge to the guide portion 14. The guide portion 14 is inclined downward relative to the horizontal plane H, so that the oil stains can flow along the inclined direction of the guide portion 14. The oil stains finally converge to the bottom end 141 of the guide portion 14 along the inclined direction thereof, thereby changing the final dropping position of the oil stains at the bottom end of the heat rail 10 (i.e., the bottom end 111 of the rail body 11), preventing the oil stains from dropping from the gap between the heat rail 10 and the door plate 801, avoiding pollution to the ground of the working area, and avoiding personal injury to the operators in the operation channel 500 of the false twist texturing machine caused by the high-temperature oil drops.

[0035] Referring to Figures 1 to 3 In the present embodiment, the heat rail 10 includes a rail body 11, a plurality of grooves 13 for heating the chemical fiber formed along the length direction of the rail body 11, and groove walls 12 formed on both sides of the grooves 13. The bottom end 111 of the rail body 11 along the length direction thereof is at least partially configured with a guide portion 14 inclined downward relative to the horizontal plane H, and the bottom end of the grooves 13 and the groove walls 12 along the length direction of the rail body 11 extends to the guide portion 14.

[0036] During the heating process of the chemical fiber N in the heat box 100, the oil stains on the groove 13 and the groove wall 12 naturally flow along the inclined direction of the heat rail 10 under the action of gravity, and converge to the guide portion 14 along the directions of the arrows B1 and B2 in FIG. 6, respectively. The guide portion 14 is inclined downward relative to the horizontal plane H, so that the oil stains can flow along the inclined direction of the guide portion 14 (e.g., the direction of the arrow B3 in FIG. 6). The oil stains finally converge to the bottom end 141 of the guide portion 14 to change the final dropping position of the oil stains at the bottom end 111 of the rail body 11, and prevent the oil stains from dropping from the gap between the heat rail 10 and the door plate 801. Figure 3 Figure 3 The guide portion 14 is inclined downward relative to the horizontal plane H, so that the oil stains can flow along the inclined direction of the guide portion 14 (e.g., the direction of the arrow B3 in FIG. 6). The oil stains finally converge to the bottom end 141 of the guide portion 14 to change the final dropping position of the oil stains at the bottom end 111 of the rail body 11, and prevent the oil stains from dropping from the gap between the heat rail 10 and the door plate 801.

[0037] In some examples, the rail body 11 is formed of a hollow profile. A heat transfer medium is guided inside the rail body 11 of the hollow profile to heat the grooves 13 and the groove walls 12. The chemical fiber N travels in the grooves 13. The chemical fiber N is limited in the grooves 13 by the cooperation of the grooves 13 and the groove walls 12, so that heat is uniformly transferred to the surface of the chemical fiber N by the grooves 13 and the groove walls 12 for stable heating.

[0038] In some examples, referring to Figure 1 and Figure 3 ​As shown, the bottom end 131 of the channel 13 along the length direction of the rail body 11 extends to the guide portion 14, and the bottom end 121 of the groove wall 12 along the length direction of the rail body 11 extends to the guide portion 14. The channel 13 is configured as a U-shaped or V-shaped groove. Regardless of the U-shaped or V-shaped groove, the bottom end 131 of the channel 13 extends to the guide portion 14, so that when the oil stains flow along the groove wall 12 or the channel 13, the oil stains flow from the bottom end 131 of the channel 13 and the bottom end 121 of the groove wall 12 to the guide portion 14.

[0039] In some examples, the rail body 11 is provided with one or two channels 13 for heating the fiber N. Figure 1 As shown, the rail body 11 is provided with one or two channels 13 for heating the fiber N along the length direction of the rail body 11. The single channel (i.e., one channel 13) is suitable for heating processing of a single fiber N, and the double channel (i.e., two channels 13) is suitable for synchronous heating processing of double fibers N to improve production efficiency. The single channel or double channel structure enables the hot rail 10 to adapt to different fiber processing requirements, such as heating processing of single fibers, double fibers, or multiple fibers. The number of channels 13 can be selected according to actual production requirements to improve the versatility and flexibility of the hot rail 10.

[0040] In some examples, the rail body 11 is provided with one or two channels 13 for heating the fiber N. Figure 1 As shown, the rail body 11 is provided with one or two channels 13 for heating the fiber N along the length direction of the rail body 11. The single channel (i.e., one channel 13) is suitable for heating processing of a single fiber N, and the double channel (i.e., two channels 13) is suitable for synchronous heating processing of double fibers N to improve production efficiency. The single channel or double channel structure enables the hot rail 10 to adapt to different fiber processing requirements, such as heating processing of single fibers, double fibers, or multiple fibers. The number of channels 13 can be selected according to actual production requirements to improve the versatility and flexibility of the hot rail 10. Figure 3 As shown, the bottom end 111 of the rail body 11 is configured with a downwardly inclined guide portion 14a relative to the horizontal plane H, and the guide portion 14a forms a flow guide portion 142a extending over the bottom end 131 of the channel 13. The oil stains adhered to the surface of the groove wall 12 and the channel 13 flow to the guide portion 14a under the action of gravity, are fully guided by the guide portion 14a, and finally drip downwardly at the bottom end 141 of the flow guide portion 142a along the inclined direction thereof. The length of the flow guide portion 142a is set to change the final dripping position of the oil stains at the bottom end 111 of the rail body 11, so as to prevent the oil stains from dripping from the gap between the hot rail 10 and the door panel 801.

[0041] In some examples, the rail body 11 is provided with one or two channels 13 for heating the fiber N. Figure 6 As shown, the bottom end 111 of the rail body 11 is configured with a downwardly inclined guide portion 14a’ relative to the horizontal plane H, and the guide portion 14a’ forms a flow guide portion 142b extending over the bottom end 131 of the channel 13. The oil stains adhered to the surface of the groove wall 12 and the channel 13 flow to the guide portion 14a’ under the action of gravity, are fully guided by the guide portion 14a’, and finally drip downwardly at the bottom end 141 of the flow guide portion 142b along the inclined direction thereof. The length of the flow guide portion 142b is set to change the final dripping position of the oil stains at the bottom end 111 of the rail body 11, so as to prevent the oil stains from dripping from the gap between the hot rail 10 and the door panel 801.

[0042] In some examples, the rail body 11 is provided with one or two channels 13 for heating the fiber N. Figure 3 As shown, the bottom end 111 of the rail body 11 is configured with a downwardly inclined guide portion 14a relative to the horizontal plane H, and the guide portion 14a forms a flow guide portion 142a extending over the bottom end 131 of the channel 13. The oil stains adhered to the surface of the groove wall 12 and the channel 13 flow to the guide portion 14a under the action of gravity, are fully guided by the guide portion 14a, and finally drip downwardly at the bottom end 141 of the flow guide portion 142a along the inclined direction thereof. The length of the flow guide portion 142a is set to change the final dripping position of the oil stains at the bottom end 111 of the rail body 11, so as to prevent the oil stains from dripping from the gap between the hot rail 10 and the door panel 801. Figure 6As shown, the guide portion 14 forms an acute angle α with the horizontal plane H. The acute angle α can be selected from 15° to 75°, and is preferably from 30° to 60°. This allows the oil to flow directionally along the surface of the guide portion 14 under the action of gravity, avoiding retention on the groove wall 12 or the groove 13, and keeping the oil dripping point away from the gap between the hot rail 10 and the door panel 801.

[0043] In some examples, the guide 14 is configured as at least one of a plane or a curved surface. (See reference...) Figure 3 and Figure 6 As shown, the cross-sectional shape formed by cutting the guide section 14 along the Z-axis is a plane 14a, 14a' that is inclined downwards relative to the horizontal plane, or, refer to Figure 4 and Figure 5 As shown, the cross-sectional shape formed by cutting the guide section 14 along the Z-axis is a curved surface 14b that curves downward relative to the horizontal plane, or even a combination of a curved surface and a plane (this state is not shown), as long as it can guide the oil to flow in the guide section 14.

[0044] Based on the same inventive concept, this embodiment also discloses a heating box 100, see reference. Figure 7 As shown, the hot box 100 includes: a box body 80, and a plurality of hot rails 10 disposed within the box body 80.

[0045] In some examples, the parameter Figure 7 As shown, the housing 80 is the outer shell of the heating box 100, used to house the heating rail 10. The synthetic fiber N forms a movement path M within the heating box 100, and is heated by the high-temperature environment inside the heating box 100. Because the heating box 100 is installed at an angle on the false-twist texturing machine 1000, the heating rail 10 is also tilted with the heating box 100. Therefore, the heating rail 10 has a certain tilt angle relative to the horizontal surface, such as 50°, 55°, 60°, etc., which allows the oil to flow naturally along the tilt direction of the heating rail 10 under the action of gravity, converging towards the bottom end of the heating rail 10 along its length.

[0046] 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 flows along... Figure 3 The directions indicated by the middle arrows B1 and B2 converge at the guide section 14. The guide section 14 is inclined downwards relative to the horizontal plane H, allowing the oil to flow along the inclined direction of the guide section 14 (e.g., ...). Figure 3 The oil flows in the direction indicated by the middle arrow B3, causing the oil to eventually converge at the bottom 141 of the guide section 14, thereby changing the final dripping position of the oil at the bottom of the hot rail 10 (i.e., the bottom 111 of the rail body 11) and preventing the oil at the bottom of the hot rail 10 from dripping from the gap between the hot rail 10 and the door panel 801.

[0047] In some examples, the parameter Figure 7 and Figure 8As shown, the hot box 100 also includes: a flow guiding device 20, the flow guiding device 20 being directed in the vertical direction (i.e., Figure 7 The flow guiding device 20 is located below the rail body 11 in the direction indicated by the Z-axis. The flow guiding device 20 includes: a flow guiding wall 21, which forms a flow guiding cavity 210 that is inclined downward relative to the horizontal plane, and a flow guiding pipe 22 that connects to the flow guiding cavity 210. The end of the flow guiding cavity 210 near the rail body 11 forms an opening 2101, and the vertical normal V of the bottom end 141 of the guiding part 14 along its inclined direction intersects with the collection surface P defined by the opening 2101 of the flow guiding cavity 210.

[0048] oil stains along Figure 8 The oil converging at the bottom 141 of the guide section 14 in the direction indicated by the middle arrow B1, under the action of gravity, flows from the bottom 141 of the guide section 14 along... Figure 8 As indicated by arrow B2, the oil drips downwards. Since the collecting surface P intersects the vertical normal V of the bottom end 141 of the guide section 14, the oil droplets will pass through the opening 2101 and enter the guide cavity 210 during their downward dripping. The oil will flow along the guide wall 21 and eventually into the guide pipe 22, where it will be collected and discharged from the heat box 100. This prevents oil from dripping from the bottom end of the heat rail 10 through the gap between the heat rail 10 and the door panel 801. By collecting the oil dripping from the bottom end of the heat rail 10 and discharging it from the heat box 100 through the guide device 20, the high-temperature oil droplets effectively prevent ground contamination and avoid personal injury to operators in the working passage 500 of the false twisting machine.

[0049] In some examples, the parameter Figure 1 , Figure 7 and Figure 9 As shown, the hot box 100 also includes: a flow guiding device 20, which abuts against the bottom end 111 of the rail body 11; the flow guiding device 20 includes: a flow guiding wall 21, one end 2111 of the flow guiding wall 21 near the hot rail 10 abuts against the flow guiding part 142 formed by the guide part 14 or partially extends into the flow guiding part 142 formed by the guide part 14, the flow guiding wall 21 forms a flow guiding groove 210 that is inclined downward relative to the horizontal surface, and a flow guiding pipe 22 that connects to the flow guiding groove 210, so that the flow guiding wall 21 guides the oil from the guide part 14 to the flow guiding pipe 22.

[0050] 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 in the guide part 14. The oil flows along the inclined direction of the guide part 14, and the oil flows from the guide part 142 along... Figure 9The oil dirt flows along the direction indicated by the middle arrow B1 to the flow guide wall 21. Since the flow guide wall 21 abuts against the flow guide portion 142 or partially extends into the flow guide portion 142, the oil dirt can flow along the flow guide portion 142 to the flow guide wall 21 to enter the flow guide groove 210 and be guided by the flow guide wall 21 to flow along the direction indicated by the middle arrow B2 to the flow guide pipe 22 to be discharged from the heat box 100 through the flow guide pipe 22, thereby preventing the oil dirt from dripping from the gap between the hot rail 10 and the door panel 801. Figure 9 The oil dirt flows along the direction indicated by the middle arrow B21 to be guided into the flow guide pipe 22 to be discharged from the heat box 100 through the flow guide pipe 22, thereby preventing the oil dirt from dripping from the gap between the hot rail 10 and the door panel 801.

[0051] In some examples, as shown in FIG. 1, the flow guide wall 21 is arranged to abut against the bottom end 141 of the flow guide portion 142 along the inclined direction of the flow guide portion 142 or partially extend into the bottom end 141 of the flow guide portion 142. Figure 8 As shown in FIG. 1, the flow guide wall 21 is arranged to abut against the bottom end 141 of the flow guide portion 142 along the inclined direction of the flow guide portion 142 or partially extend into the bottom end 141 of the flow guide portion 142. Figure 9 As shown in FIG. 1, the flow guide wall 21 is arranged to abut against the bottom end 141 of the flow guide portion 142 along the inclined direction of the flow guide portion 142 or partially extend into the bottom end 141 of the flow guide portion 142.

[0052] In some examples, as shown in FIG. 1, the flow guide wall 21 is arranged to abut against the bottom end 141 of the flow guide portion 142 along the inclined direction of the flow guide portion 142 or partially extend into the bottom end 141 of the flow guide portion 142. Figure 9 As shown in FIG. 1, the flow guide wall 21 includes a bottom wall 211 abutting against the bottom end 141 of the flow guide portion 142 or partially extending into the bottom end 141 of the flow guide portion 142, two oppositely arranged side walls 212 extending along the length direction of the bottom wall 211, a guide wall 213 downwardly inclined relative to the horizontal plane and transversely connecting the side walls 212, the guide wall 213 extending towards the hot rail 10 and partially extending over the vertical normal line V of the bottom end 141 of the flow guide portion 142, the guide wall 213 forming an obtuse angle β with the vertical normal line V.

[0053] The bottom wall 211 abuts against the bottom end 141 of the flow guide portion 142 or partially extends into the bottom end 141 of the flow guide portion 142 to ensure that the oil dirt can flow along the flow guide portion 142 to the bottom wall 211 to enter the flow guide groove 210. Figure 9 The oil dirt flows along the direction indicated by the middle arrow B1 to the flow guide wall 21. Since the flow guide wall 21 abuts against the flow guide portion 142 or partially extends into the flow guide portion 142, the oil dirt can flow along the flow guide portion 142 to the flow guide wall 21 to enter the flow guide groove 210 and be guided by the flow guide wall 21 to flow along the direction indicated by the middle arrow B2 to the flow guide pipe 22 to be discharged from the heat box 100 through the flow guide pipe 22, thereby preventing the oil dirt from dripping from the gap between the hot rail 10 and the door panel 801.Figure 9 The oil stains falling in the direction indicated by the middle arrow B22 directly fall downward, extend toward the hot rail 10 through the guide wall 213, and partially extend through the vertical normal line V of the bottom end 141 of the flow guide part 142, so that the oil stains falling downward can directly fall on the guide wall 213, and then form an obtuse angle β with the vertical normal line V through the guide wall 213, so that the guide wall 213 can guide the oil stains to flow along the flow guide groove 210 under the action of gravity. Figure 9 The oil stains flow in the direction indicated by the middle arrow B4 to enter the flow guide pipe 22, and are concentrated and discharged out of the hot box 100 through the flow guide pipe 22. In the process of guiding the oil stains to the flow guide pipe 22 by the guide wall 213, the oil stains flowing on the guide wall 213 can be shielded by the side wall 212 to prevent the oil stains from escaping from the guide wall 213 to the inside or outside of the box body 80.

[0054] The hot box 100 disclosed in the present application collects the oil stains at the bottom end of the hot rail 10 through the flow guide device 20 and discharges the oil stains out of the hot box 100, thereby reducing the demand for air volume of the negative pressure source and eliminating the need for continuous high-intensity oil fume extraction operation. The exhaust pipe 70 communicating with the flow guide pipe 22 is arranged below the hot box 100. When the exhaust pipe 70 is connected to the negative pressure source, the flow guide device 20 can collect the oil stains at the bottom end 101 of the hot rail 10 and discharge the oil stains out of the hot box 100, thereby reducing the demand for air volume of the negative pressure source and eliminating the need for continuous high-intensity oil fume extraction operation. Even when the exhaust pipe 70 is not connected to the negative pressure source, the oil stains at the bottom end 101 of the hot rail 10 can flow into the exhaust pipe 70 through the flow guide device 20 under the action of gravity and be discharged out of the hot box 100, thereby reducing the heat loss in the hot box 100 caused by the oil fume extraction operation and reducing energy waste, so as to achieve the purpose of energy saving and consumption reduction of the hot box 100 and the false twist texturing machine 1000 containing the hot box 100. The energy consumption to be reduced in the present application can be considered as the energy consumption produced by the hot box 100 containing the hot rail 10, or as the energy consumption produced by the false twist texturing machine 1000 containing the hot box 100 as a whole, or as the energy consumption produced by the false twist texturing machine 1000 and the negative pressure source together, or as the energy consumption produced by the negative pressure source.
