Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machinery, and particularly relates to a elasticizer. BACKGROUND

[0002] The elasticizer is a silk thread processing device for pre-drawing, false twisting, deforming (elasticizing) and winding of polyester, chinlon pre-oriented silk or other colored silk. The elasticizer comprises a conveying device, a heating device, a cooling device, a false twisting device, a post-processing device and a winding device. The silk thread is heated and deformed, then cooled, and then post-processed and shaped. The elasticizer in the prior art includes two types of large elasticizer and small elasticizer.

[0003] The prior art large take-up machine (for example, CN115613175B) has large batch production capacity and supports multiple process modes, but the device is bulky, especially the upper heat box is tilted upward at a large angle, which results in excessive space occupation and excessive height. The upper heat box is usually suspended above the main rack by support structures such as columns or supports, so that the installation position of the upper heat box on the main rack is high, thereby increasing the overall height of the large take-up machine. At the same time, the upper heat box has a large inclination angle relative to the horizontal plane, which increases the space occupation of the upper heat box in the vertical direction, further increasing the overall height of the large take-up machine. The yarn that needs to be heated is guided to the upper heat box by the threading device (also known as "head rod" or "head rail" or "head device") during the conveying process from the W1 roller, and one threading device needs to be arranged for each yarn path and multiple threading devices need to be arranged in parallel. Therefore, the yarn of the large take-up machine has a long conveying path before feeding into the false twist device, and the long conveying path causes damage to the yarn during conveying. The long conveying path will inevitably cause tension fluctuations and other undesirable phenomena in the yarn. At the same time, due to the high installation position of the upper heat box on the main rack, the distance from the ground is far, so that the maintenance personnel need to climb to the maintenance platform at the top of the main rack to access the upper heat box and perform maintenance and cleaning. Due to the dense parallel arrangement of the threading devices, the operation space is small, the maintenance personnel's movements are limited, and the maintenance operation is complex and has safety hazards. The threading device is usually located between the upper heat box and the maintenance platform, making it difficult for maintenance personnel to directly observe or touch the hot rail or heating elements inside the upper heat box. Maintenance personnel need to detour or disassemble part of the threading device to form a space for maintenance operation, so there is a long maintenance time, inconvenient operation, and low maintenance efficiency. In addition, the prior art large take-up machine has a high installation position of the upper heat box, which also requires a long handle component to open and close the heat box door, thereby increasing the manufacturing cost of the device. Therefore, the existing large take-up machine requires a high vertical space in the factory, and additional threading devices, maintenance platforms, and long heat box door handles are required, which complicates the structure of the top of the main rack and significantly increases the manufacturing and maintenance costs of the device.

[0004] Although the small take-up machine in the prior art (for example, CN209702951U) is compact in size and small in space occupation, it has a low speed and can support fewer process modes. For example, it is difficult to support false twisting and texturing of core yarn or colored yarn. In particular, the size of the winding bobbin and the weight of the final cheese may be limited, and it is not possible to produce a large cheese like a large take-up machine. Therefore, it is necessary to frequently change the cheese that has been wound into shape manually, which has the disadvantage of complicated operation. At the same time, the small take-up machine is usually provided with a footboard in the operation channel between the main frame and the auxiliary frame. The footboard is usually a fixed metal platform that penetrates the operation channel. The footboard is provided with a strip-shaped gap for the yarn after heat setting to pass through it transversely and is finally wound into a spindle by the winding device, so that the operation channel cannot meet the passage of the doffer trolley. The wound cheese can only be manually transported, resulting in increased labor costs and reduced production efficiency. Therefore, the overall structure of the small take-up machine is not suitable for a large take-up machine.

[0005] It should be noted that the above introduction to the background art is only for the convenience of clearly and completely describing the technical solutions of the present application and facilitating the understanding of those skilled in the art. The above technical solutions cannot be considered as known to those skilled in the art merely because they are described in the background art section of the present application. SUMMARY

[0015] The support assemblies comprise a first cross beam arranged on the top of the main frame.

[0016] The outlet end extends obliquely upward beyond the first cross beam in the oblique direction of the deforming hot box. The inlet end extends obliquely downward beyond the first cross beam in the oblique direction of the deforming hot box.

[0017] As a further improvement of the present application, the angle between the deforming hot box and the horizontal plane is greater than 20° and less than 30°, or the angle between the deforming hot box and the horizontal plane is greater than 30° and less than or equal to 45°.

[0018] As a further improvement of the present application, the texturing machine does not comprise a head forming device. The inlet end is close to the first conveying mechanism.

[0019] As a further improvement of the present application, the processing group further comprises a turning guide arranged between the deforming hot box and the cooling device. The wrapping angle of the yarn introduced into the cooling device from the outlet end through the turning guide is greater than or equal to 80° and less than or equal to 100°.

[0020] As a further improvement of the present application, the wrapping angle is 90°.

[0021] As a further improvement of the present application, the height of the turning guide relative to the main frame is adjustable to adjust the wrapping angle.

[0022] As a further improvement of the present application, the wire and the turning guide are in contact to form a wire conveying highest point, the wire conveying highest point is above the operation channel and between the deforming hot box and the cooling device.

[0023] As a further improvement of the present application, the cooling device comprises a cold rail and metal radiating fins attached to the outer surface of the cold rail, the length of the cold rail is 60-90cm.

[0024] The length of the deforming hot box is 1.2-1.3m, the heating temperature of the deforming hot box is 180-250℃.

[0025] The deforming hot box comprises a box body, a plurality of hot rails arranged in the box body and a channel for accommodating the hot rails.

[0026] And a smoke exhaust pipe arranged only on the top of the box body and communicated with the channel.

[0028] The wire-out end is supported by a first fixing member connecting the first cross beam, and the wire-in end is supported by a second fixing member connecting the side frame and / or the second cross beam.

[0029] As a further improvement of the present application, the two side walls of the deforming hot box along the first direction are outwardly protruded to form a fixing rod, and the first fixing member is configured with a groove with an opening for the fixing rod to be inserted.

[0030] The second fixing member is extended towards the wire-in end to form a supporting plate, and the supporting plate is supported by the bottom end side wall of the deforming hot box along the inclined direction.

[0031] As a further improvement of the present application, the winding device is arranged on the center frame.

[0032] The elasticizer further comprises a setting hot box arranged vertically on the center frame.

[0033] Compared with the prior art, the present application has the following advantages:

[0034] By installing the deforming hot box on the top of the main frame relative to the horizontal plane at an angle greater than 20° and less than or equal to 45°, the angle between the deforming hot box and the horizontal plane is reduced, the length of the deforming hot box in the vertical direction is reduced, the space occupation of the deforming hot box in the vertical direction is reduced, the overall height of the elasticizer is reduced, the volume of the elasticizer is reduced, the height requirement of the factory building is reduced, and especially the conveying length of the yarn in the processing group is shortened, the damage risk of the yarn in the conveying process is effectively reduced, and the phenomenon of yarn tension fluctuation caused by too long conveying path is reduced. Since the vertical distance between the deforming hot box and the ground is reduced, the maintenance personnel do not need to climb to the top of the main frame, stand on the ground, and maintain and clean the deforming hot box in the operation channel, which simplifies the operation process, reduces the maintenance time, and improves the maintenance efficiency. The maintenance personnel do not need to open and close the hot box door through a long handle, the length of the handle for opening and closing the hot box door is shortened, the maintenance personnel can open and close the hot box door through a shorter handle, and the material, processing and assembly costs of the handle are reduced. At the same time, by omitting the threading device, the yarn can be guided to the yarn inlet end without the aid of the threading device, thereby shortening the conveying path of the yarn from the first conveying mechanism to the guide ceramic piece arranged at the yarn inlet end.

[0044] 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. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention. The accompanying drawings in this invention are not strictly drawn to scale, and the specific dimensions of each structure can be determined according to actual needs. The accompanying drawings described in this invention are merely structural schematic diagrams.

[0045] The term "lateral" refers to the direction indicated by arrow X in the accompanying drawings of this invention, and it is a bidirectional direction. The term "first direction" refers to the direction indicated by arrow X in the accompanying drawings of this invention. Figure 3 The direction indicated by the middle arrow Y is bidirectional; the term "vertical" refers to the direction indicated by the appendix of this invention. Figure 1 The direction indicated by the middle arrow Z is bidirectional.

[0046] like Figure 1 The diagram shows a vertical cross-section of the texturing machine 100, illustrating the complete processing flow of the yarn S at one processing station. Specifically, at this processing station, the yarn S is drawn from the feed bobbin 41 of the original yarn holder 40, and sequentially undergoes guiding, deformation, and stretching processes by the processing group within the main frame 10. Finally, the processed yarn S is wound into a spindle 271 by the winding device 27. The processing group is integrated within the main frame 10, forming a partial yarn processing path around the operating channel 50, ensuring the coordinated operation of various processing devices (such as the first conveying mechanism 22, the deformation heating box 20, the cooling device 23, the false twisting device 24, the second conveying mechanism 25, the third conveying mechanism 26, the oiling device 29, and the winding device 27).

[0047] The texturing machine 100 has multiple processing stations arranged side-by-side along a first direction, each station independently performing the deformation and stretching operations on a single filament S. For example, hundreds of processing stations with identical structures can be arranged side-by-side to achieve high-density, continuous production. Since the structural design of each processing station is consistent, this embodiment uses... Figure 1 Taking a single processing station as an example, the layout and function of the devices (such as the deformation heating box 20, cooling device 23, etc.) included in its processing group are explained. This example can represent the general structure of all processing stations, which is helpful for understanding the working principle and technical features of the texturing machine 100 (hereinafter referred to as "the equipment") referred to in this invention.

[0048] In some examples, the main frame 10 comprises a center frame 101 and side frames 102. The cooling device 23 and the texturing heat box 20 are both obliquely arranged above the operation channel 50. The first conveying mechanism 22 is arranged on the side frame 102. The cooling device 23 and the texturing heat box 20 are both obliquely arranged on the top of the main frame 10. The false twist device 24 and the second conveying mechanism 25 are vertically spaced apart on the center frame 101. The yarn frame 40 is arranged transversely adjacent to the main frame 10. A plurality of yarn feed bobbins 41 are arranged on the yarn frame 40 in an overlapping manner. The yarns S drawn out of the yarn feed bobbins 41 are respectively assigned to one of the processing positions.

[0049] As shown in Figure 1 , the processing position has the first conveying mechanism 22 drawing out the yarn S from the yarn feed bobbin 41. A pre-treatment zone is formed between the first conveying mechanism 22 and the second conveying mechanism 25. The yarn S is heated, cooled, textured and stretched in the pre-treatment zone. In the pre-treatment zone, the texturing heat box 20, the cooling device 23 and the false twist device 24 are arranged in sequence along the yarn conveying path. The setting heat box 28 and the third conveying mechanism 26 are arranged in the yarn conveying path after the second conveying mechanism 25. The third conveying mechanism 26 is located below the second conveying mechanism 25, so as to form a post-treatment zone between the second conveying mechanism 25 and the third conveying mechanism 26. The setting heat box 28 is vertically arranged on the center frame 101 and formed in the post-treatment zone, for maintaining uniform relaxation of the yarn S and with as low yarn tension as possible. The winding device 27 is arranged in the yarn conveying path after the third conveying mechanism 26. The winding device 27 is arranged on the center frame 101. The treated yarn S is wound into a spool 271 by the winding device 27. The setting heat box 28 is optional for the post-treatment of the yarn S. For the post-treatment of the yarn S which does not need to perform heat setting treatment (for example, polyamide yarn), the setting heat box 28 can be omitted.

[0050] Please refer to Figure 1 to Figure 9 for a specific embodiment of the elasticizer 100 of the present application.

[0051] As shown in Figure 1An embodiment of the elasticizer 100 is shown, which comprises a main frame 10, a processing group arranged on the main frame 10 and used for stretching, deforming and winding the yarn S, the processing group comprising a first conveying mechanism 22, a deformation heat box 20, a cooling device 23, a false twist device 24, a second conveying mechanism 25, a third conveying mechanism 26 and a winding device 27; the deformation heat box 20 is arranged obliquely on the top of the main frame 10, and an included angle a formed between the deformation heat box 20 and the horizontal plane is greater than 20° and less than or equal to 45°; one end of the deformation heat box 20 through which the yarn S enters is an inlet end 201, and the other end of the deformation heat box 20 through which the yarn S exits is an outlet end 202; the height of the inlet end 201 is lower than the height of the outlet end 202; an operating channel 50 is formed on the inner side of the main frame 10, and the cooling device 23 and the deformation heat box 20 are arranged obliquely above the operating channel 50; the first conveying mechanism 22 and the second conveying mechanism 25 can be a winding conveying mechanism or a clamping conveying mechanism, and the third conveying mechanism 26 can be a clamping conveying mechanism.

[0052] Compared with the elasticizer in the prior art, the elasticizer 100 of the present application reduces the installation position of the deformation heat box 20 on the main frame 10 by arranging the deformation heat box 20 obliquely on the top of the main frame 10 relative to the horizontal plane, thereby reducing the overall height of the elasticizer 100. At the same time, the included angle a formed between the deformation heat box 20 and the horizontal plane is greater than 20° and less than or equal to 45°, so as to reasonably reduce the oblique angle of the deformation heat box 20 relative to the horizontal plane, reduce the length of the deformation heat box 20 in the vertical direction, thereby reducing the space occupation of the deformation heat box 20 in the vertical direction, further reducing the overall height of the elasticizer 100, reducing the volume of the elasticizer 100, reducing the height requirement of the factory building, saving the construction cost of the factory building, and making the elasticizer 100 suitable for installation in a low-layer high factory building (for example, the layer height is less than 3 meters). The overall height of the elasticizer 100 can be reduced to 2.5 meters.

[0053] Meanwhile, by setting the height of the wire inlet end 201 to be lower than the height of the wire outlet end 202, the wire threading device can be omitted, and the yarn S can be guided to the wire inlet end 201 without the aid of the wire threading device, thereby shortening the delivery path of the yarn S from the first delivery mechanism 22 to the deforming hot box 20 through the first wire guide 209 arranged at the wire inlet end 201, reducing the risk of damage to the yarn S during delivery, and reducing the phenomenon of yarn tension fluctuation caused by an excessively long delivery path, and enabling the yarn S to enter the deforming hot box 20 in a shorter path, thereby improving the processing speed of the yarn. At the same time, by lowering the installation position of the deforming hot box 20 on the main rack 10, the vertical distance between the deforming hot box 20 and the ground 300 is reduced, and the deforming hot box 20 is arranged above the operation channel 50, so that the maintenance personnel can perform maintenance and cleaning of the hot track 204 or other parts in the deforming hot box 20 in the operation channel 50 without climbing to the top of the main rack, simplifying the operation process, reducing the maintenance time, and improving the maintenance efficiency. In addition, by reducing the vertical distance between the deforming hot box 20 and the ground 300, the maintenance personnel can shorten the length of the handle for opening and closing the hot box door, and the maintenance personnel can open and close the hot box door 205 through a shorter handle 206, thereby reducing the material, processing and assembly cost of the handle.

[0054] The present application reduces the vertical distance between the deforming hot box 20 and the ground 300 by lowering the installation position of the deforming hot box 20 on the main rack 10, thereby eliminating the need to set a maintenance platform above the main rack 10, and by omitting the wire threading device, the space at the top of the main rack 10 is released, and the complexity of the structure at the top of the main rack 10 is avoided. Moreover, by shortening the length of the handle, the hot box door opening mechanism is simplified, and by omitting the configuration of the maintenance platform, the long handle, the wire threading device and other components, the manufacturing and maintenance cost of the equipment is effectively reduced, and the structure of the texturing machine 100 is more compact. While maintaining the compactness of the equipment, the speed is improved, and larger size bobbin can be compatible, supporting the production of super large wound yarn cake. Moreover, it supports the false twist and deformation processing of high value-added products such as core spun yarn and color wrapped yarn. In addition, no step plate is needed in the operation channel 50, ensuring that the operation channel 50 is completely unobstructed, so that the operation channel 50 meets the traffic demand of the artificial and doffing trolley 60, so as to facilitate the artificial to place the wound yarn spindle 271 in the doffing trolley 60 for collection, without the need for frequent manual handling, saving labor resources.

[0055] In some examples, the deforming hot box 20 adopts a biphenyl gas phase heating method to heat treat the yarn S. The inclination angle of the deforming hot box 20 using biphenyl gas phase heating relative to the horizontal plane cannot be too large (for example, greater than 45°) or too small (for example, less than 20°).

[0056] When the inclination angle of the deformation oven 20 is too large (for example, greater than 45°), the yarn S runs continuously at high speed in the deformation oven 20, the conveying path of the yarn S entering and leaving the deformation oven 20 is steeper, and the yarn S needs to overcome greater downward pulling force caused by its own weight, so higher tension needs to be applied to the yarn S at the yarn-out end 202 and the yarn-in end 201 of the deformation oven 20 to maintain stable running of the yarn S. However, too high tension can easily cause the yarn S to be stretched too much, resulting in fuzzing or even breaking. Yarn breakage can cause production interruption and increase the waste yarn rate. Moreover, when the inclination angle of the deformation oven 20 is too large, the biphenyl vapor quickly accumulates in the upper part of the deformation oven 20, resulting in over-saturation and too high temperature of the biphenyl vapor in the upper part of the deformation oven 20, while the biphenyl vapor in the lower part is insufficient. This causes the yarn S to be overheated in the upper part of the deformation oven 20 and underheated in the lower part of the deformation oven 20, forming a temperature gradient, causing uneven heating of the yarn S, and resulting in insufficient deformation or inconsistent or uneven deformation of the yarn S. For example, in the locally overheated area of the yarn S, thermal degradation can occur, affecting the bulkiness and hand feeling; in the locally underheated area of the yarn S, the optimal deformation temperature is not reached, resulting in poor twist transfer, producing dead yarn, and reducing the elasticity and dyeing uniformity of the finished yarn.

[0057] The yarn S needs to be in moderate contact with the hot rails 204 in the deformation oven 20 to achieve efficient heat transfer. When the inclination angle of the deformation oven 20 is too small (for example, less than 20°), the yarn S runs almost horizontally in the deformation oven 20, the tension of the yarn S is reduced, and slackening or drifting easily occurs, thereby reducing the effective contact area of the yarn S with the hot rails 204, resulting in reduced heat transfer rate and insufficient heating efficiency, which is not conducive to subsequent deformation processing of the yarn S by the false twist device 24. Moreover, when the inclination angle of the deformation oven 20 is too small, the uniform diffusion of the biphenyl vapor in the deformation oven 20 is not conducive, and the flowability is reduced. The biphenyl vapor is easily accumulated in the middle or lower part of the deformation oven 20, while the upper part of the deformation oven 20 is insufficient in biphenyl vapor. This causes the yarn S to be overheated in the middle or lower part of the deformation oven 20 and underheated in the upper part of the deformation oven 20, forming a temperature gradient, causing uneven heating of the yarn S, which is also not conducive to subsequent deformation processing of the yarn S by the false twist device 24, and resulting in insufficient deformation or inconsistent or uneven deformation of the yarn S.

[0058] For example, the partial overheating area of the yarn S may cause thermal degradation, affecting the bulkiness and hand feeling; the partial underheating area of the yarn S does not reach the optimal deformation temperature, resulting in poor twist transfer, producing dead yarn, reducing the elasticity of the finished yarn and uneven dyeing. In the gas phase heating system (not shown) of the deformation heat box 20, when the inclination angle of the deformation heat box 20 is too small, after the condensation of biphenyl vapor releases heat, the condensed biphenyl liquid is driven by gravity, and the return flow of the condensed biphenyl liquid is insufficient. The condensed biphenyl liquid flows slowly in the return flow pipeline (not shown) and stays in the return flow pipeline, causing insufficient biphenyl liquid flow in the return liquid tank (not shown), and the liquid level in the liquid tank is too low, which requires additional biphenyl liquid, increasing the operating cost.

[0059] In summary, referring to Figure 1 As shown, the present application can ensure that the downward pulling force generated by the weight of the yarn S is balanced with the running tension by setting the included angle a between the deformation heat box 20 and the horizontal plane to any one of the inclination angles in the range of (20°, 45°], so that the tension of the yarn S is stable, preventing the yarn S from being stretched excessively due to excessive tension, which may cause fuzzing or even breakage, thereby reducing the waste yarn rate, eliminating fiber fatigue damage, and preventing relaxation or drift caused by excessive tension, increasing the effective contact area between the yarn S and the hot rail 204 to improve the heat transfer rate and heating efficiency. And, the biphenyl vapor can diffuse freely in the deformation heat box 20, avoiding the accumulation of biphenyl vapor in the upper or lower part of the deformation heat box 20, and uniformly diffusing and distributing in the deformation heat box 20 to ensure temperature consistency, improve heating efficiency, and heat the yarn S uniformly throughout the path in the deformation heat box 20, facilitating subsequent deformation and processing of the yarn S by the false twist device 24 to achieve higher quality, eliminate dead yarn, and ensure the elasticity and dyeing uniformity of the finished yarn. At the same time, the condensed biphenyl liquid returns to the liquid tank along the return flow pipeline quickly, avoiding condensate retention. The return flow efficiency of the condensed biphenyl liquid is improved, reducing the need for biphenyl replenishment and reducing operating costs.

[0060] In some examples, the included angle a between the deformation heat box 20 and the horizontal plane is greater than 20° and less than 30°, or the included angle a between the deformation heat box 20 and the horizontal plane is greater than 30° and less than or equal to 45°.

[0061] Exemplarily, the included angle a can be an integer angle of 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 31°, 35°, 40°, 44° or 45°, or a non-integer angle, or a range defined by at least two integer angles or non-integer angles; for example, the included angle a is greater than 20° and less than or equal to 24°, or the included angle a is greater than 21° and less than or equal to 26°, or the included angle a is greater than 24° and less than 30°, or the included angle a is greater than 30° and less than or equal to 45°, or the included angle a is greater than 22.3° and less than 24.8°, or the included angle a is greater than 31.8° and less than 43.2°, or other angle ranges.

[0062] Further, the included angle a formed by the deforming hot box 20 and the horizontal plane can be an integer angle of 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 31°, 32°, 35°, 40°, 43° or 44°, or a non-integer angle, or a range defined by at least two integer angles or non-integer angles; for example, the included angle a is greater than or equal to 21° and less than or equal to 29°, or the included angle a is greater than or equal to 31° and less than or equal to 44°, or the included angle a is greater than or equal to 21.6° and less than or equal to 28.7°, or the included angle a is greater than or equal to 32.2° and less than or equal to 44.5°, or other angle ranges.

[0063] In some examples, the included angle a formed by the deforming hot box 20 and the horizontal plane is greater than 21° and less than 45°, or greater than 21.6° and less than 44.5°, or greater than 22.3° and less than 43.2°, or greater than 24° and less than 30°, or greater than 31.8° and less than 29.2°, or other angle ranges. Figure 1 The deforming hot box 20 can be arranged on the top of the main rack 10, and the included angle a formed by the deforming hot box 20 and the horizontal plane is greater than 21° and less than 45°, or greater than 21.6° and less than 44.5°, or greater than 22.3° and less than 43.2°, or greater than 24° and less than 30°, or greater than 31.8° and less than 29.2°, or other angle ranges. Figure 3 As shown, the top of the main rack 10 forms two groups of support assemblies 11 extending in the transverse direction, and the support assemblies 11 are arranged on both sides of the deforming hot box 20 in the first direction to fix the deforming hot box 20 on the top of the main rack 10.

[0064] The prior art large elasticizer generally suspends the upper hot box above the main rack through support structures such as columns or supports, so that the installation position of the upper hot box on the main rack is high, thereby increasing the overall height of the elasticizer, requiring a high layer height of the factory building, and having a low space utilization rate. The overall height of the prior art large elasticizer is about 5.5 meters, and the layer height requirement of the installation factory building is usually required to be 6 meters.

[0065] The support assembly 11 is formed on the top of the main frame 10 and is connected to the top of the main frame 10 in the horizontal direction to provide horizontal support for the deforming oven 20, without the need for additional support structures such as columns or supports, avoiding the vertical space stacking of the conventional support structure, so that the overall installation position of the deforming oven 20 is lower than that of the existing upper oven, thereby reducing the overall height of the elasticizer 100, reducing the vertical space occupied by the elasticizer 100, suitable for standard factory environment, saving building cost. The lateral support assemblies 11 on both sides of the deforming oven 20 can evenly share the dead weight and running vibration of the deforming oven 20, reduce the displacement risk of the deforming oven 20, and ensure the stability of the wire conveying.

[0066] In some examples, the method includes Figure 1 to Figure 3 As shown, the main frame 10 includes a center frame 101 and a side frame 102; the support assembly 11 is connected to the center frame 101 and the side frame 102 at the two ends in the lateral direction; the support assembly 11 includes a first cross beam 111, which is arranged on the top of the main frame 10; the wire outlet end 202 extends upward along the inclined direction of the deforming oven 20 and passes through the first cross beam 111, and the wire inlet end 201 extends downward along the inclined direction of the deforming oven 20 and passes through the first cross beam 111.

[0067] The large elasticizer in the prior art usually suspends the upper oven above the main frame by support structures such as columns or supports, so that the installation position of the upper oven on the main frame is high, the wire inlet end of the upper oven is also fixed at a high position by the support structure, and the high-position installation of the wire outlet end of the upper oven needs to occupy the space above the top of the main frame, thereby causing the structure to be stacked in the vertical space layout of the upper oven and the main frame, and the overall height of the machine is increased.

[0068] The support assembly 11 is directly fixed to the top of the main frame 10, such as Figure 1 The first cross beam 111 is connected to the center frame 101 and the side frame 102 at the two ends in the lateral direction, without the need for additional columns or supports to support the deforming oven 20, releasing the space above the top of the main frame 10, avoiding the vertical space layout of the existing upper oven and the main frame, so that the installation position of the deforming oven 20 is lowered to the vicinity of the top of the main frame 10, thereby reducing the overall height of the elasticizer 100.

[0069] The present application reduces the height of the yarn inlet end 201, reduces the distance between the yarn inlet end 201 and the first conveying mechanism 22, so that the yarn S can be guided to the yarn inlet end 201 without the help of a threading device, shortens the conveying path of the yarn S from the first conveying mechanism 22 to the deforming hot box 20 through the first yarn guide 209, reduces the friction resistance of the yarn S, reduces the risk of damage to the yarn S during conveying, reduces the phenomenon of yarn tension fluctuation caused by too long conveying path, and enables the yarn S to enter the deforming hot box 20 with a shorter path, thereby improving the processing speed of the yarn. At the same time, the low position of the yarn inlet end 201 facilitates the threading or maintenance of the maintenance personnel, and avoids the problem of climbing to the top of the main rack for operation in the existing upper hot box.

[0070] In some examples, the present application provides a yarn feeding device for a yarn texturing machine, comprising a main rack 10, a yarn inlet end 201, a first conveying mechanism 22, and a deforming hot box 20. Figure 1 The present application provides a yarn feeding device for a yarn texturing machine, comprising a main rack 10, a yarn inlet end 201, a first conveying mechanism 22, and a deforming hot box 20. Figure 2 As shown, the first conveying mechanism 22 is located below the yarn inlet end 201, and the yarn conveying path formed between the deforming hot box 20 and the first conveying mechanism 22. The yarn S is conveyed to the yarn inlet end 201 through the yarn stopper 21 arranged on the main rack 10 under the guidance of the first conveying mechanism 22. The first conveying mechanism 22 is arranged below the yarn inlet end 201, and the yarn S directly enters the yarn inlet end 201 of the hot box 20 under the guidance of the yarn stopper 21, without the need for additional threading devices. After canceling the threading device, the number of equipment parts can be reduced, the manufacturing cost of the equipment can be reduced, and the threading step can be reduced, thereby reducing the difficulty of manual operation. After the first conveying mechanism 22 draws out the yarn S from the yarn supply bobbin 41, the yarn S directly enters the deforming hot box 20 under the guidance of the yarn stopper 21, thereby shortening the yarn conveying path, reducing the risk of damage to the yarn S during conveying, and reducing the tension fluctuation of the yarn S.

[0071] In some examples, the present application provides a yarn feeding device for a yarn texturing machine, comprising a main rack 10, a yarn inlet end 201, a first conveying mechanism 22, and a deforming hot box 20. Figure 1 The present application provides a yarn feeding device for a yarn texturing machine, comprising a main rack 10, a yarn inlet end 201, a first conveying mechanism 22, and a deforming hot box 20. Figure 2 As shown, the first conveying mechanism 22 is located below the yarn inlet end 201, and the yarn conveying path formed between the deforming hot box 20 and the first conveying mechanism 22. The yarn S is conveyed to the yarn inlet end 201 through the yarn stopper 21 arranged on the main rack 10 under the guidance of the first conveying mechanism 22. The first conveying mechanism 22 is arranged below the yarn inlet end 201, and the yarn S directly enters the yarn inlet end 201 of the hot box 20 under the guidance of the yarn stopper 21, without the need for additional threading devices. After canceling the threading device, the number of equipment parts can be reduced, the manufacturing cost of the equipment can be reduced, and the threading step can be reduced, thereby reducing the difficulty of manual operation. After the first conveying mechanism 22 draws out the yarn S from the yarn supply bobbin 41, the yarn S directly enters the deforming hot box 20 under the guidance of the yarn stopper 21, thereby shortening the yarn conveying path, reducing the risk of damage to the yarn S during conveying, and reducing the tension fluctuation of the yarn S.

[0072] The prior art yarn texturing machine needs to set yarn guide porcelain pieces at each folding point of the yarn path, and the yarn repeatedly contacts between the multiple yarn guide porcelain pieces, which causes the accumulation of friction resistance, and the yarn is prone to fluffing or even breaking due to excessive friction under high-speed operation. The accumulation of multiple yarn guide porcelain pieces causes the yarn to have tension fluctuation and damage during conveying. At the same time, when the yarn is broken or the POY yarn (i.e., a lower concept of the yarn in the yarn supply bobbin 41 that has not been processed) is replaced, the complexity of re-establishing the yarn conveying path is increased.

[0073] By eliminating the yarn-forming device (also known as the "yarn-forming rod," "yarn-forming track," or "threading device") and its associated guide ceramics, the number of guide ceramics is reduced, and the yarn transport path of the yarn S is shortened. The yarn S enters the texturing heat box 20 directly from the first conveying mechanism 22 via the anti-twist device 21 and the first guide ceramics 209, reducing the contact points and frequency of contact between the yarn S and the guide ceramics during the transport path, thus lowering the risk of fuzzing or even breakage due to excessive friction. Simultaneously, the shortened yarn transport path reduces the number of frictions between the yarn S and the guide ceramics, reducing tension fluctuations and yarn damage. When changing POY raw yarn, the yarn-forming time can be shortened. This further simplifies the equipment structure and reduces manufacturing and maintenance costs. Furthermore, it eliminates the vertical and / or horizontal space occupation of the yarn-forming device and its associated guide ceramics in the texturing machine 100, making the structure of the texturing machine 100 more compact.

[0074] In some examples, the parameter Figure 1 and Figure 2 As shown, the processing group also includes: a steering guide 61, which is disposed between the deformation heat box 20 and the cooling device 23. The winding angle b formed by the wire S being introduced into the cooling device 23 from the wire exit end 202 through the steering guide 61 is greater than or equal to 80° and less than or equal to 100°.

[0075] Existing texturing machines lack guide ceramic elements between the heating chamber and the cooling device. The wire enters the cooling device directly from the heating chamber, resulting in an excessively large angle (nearly 180°). This leads to significant tension fluctuations when the wire is unguided, causing it to sway during high-speed operation and increasing the risk of wire breakage. Alternatively, some existing technologies vertically mount the cooling device in the central frame, using multiple guide ceramic elements along the wire transport path between the heating chamber and the cooling device to reduce the angle at which the wire enters the cooling device.

[0076] The steering guide 61 is a transition component between the wire outlet end 202 of the deformation heat box 20 and the cooling device 23. The second wire guide 210, which is provided at the wire outlet end 202, guides the wire S from the deformation heat box 20 through the steering guide 61 into the cooling device 23.

[0077] The larger the wrap angle b (e.g., greater than 100°), the shorter the arc length formed by the contact between the wire S and the steering guide 61, and the lower the friction between the wire S and the steering guide 61. Reduced friction leads to insufficient support from the steering guide 61 for the wire S, resulting in reduced tension in the wire S, making it prone to slack or drift, and causing the wire S to oscillate easily at high speeds. Conversely, the smaller the wrap angle b (e.g., less than 80°), the longer the arc length formed by the contact between the wire S and the steering guide 61, and the higher the friction between them. Increased friction leads to increased sliding resistance between the steering guide 61 and the wire S. Excessive friction may cause the wire S to wear easily at high speeds, leading to fuzzing or even breakage.

[0078] Furthermore, the wrap angle b can be an integer angle such as 80°, 81°, 85°, 90°, 95°, 90°, or 100°, or a non-integer angle, or a range defined by at least two integer or non-integer angles. The applicant unexpectedly discovered that by setting the wrap angle b within the range of [80°, 100°], the risk of the wire S easily swaying due to an excessively large wrap angle b, or the problem of increased wire wear due to an excessively small wrap angle b, can be reduced. In particular, when the wrap angle b is set to 90°, the tension distribution of the wire S at the steering guide 61 is uniform, reducing tension fluctuations and preventing slack or drift caused by excessively low tension, thereby achieving a good conveying effect for the wire S. The arc length formed by the contact between the wire S and the steering guide 61 is moderate. The steering guide 61 provides sufficient friction to maintain stable tension of the wire S, preventing swaying of the wire S under high-speed operation, while also avoiding damage to the wire S due to excessive friction, reducing the risk of wire breakage. This achieves both good conveying effect for the yarn S and reduces damage to the yarn S, while also lowering the overall height of the texturing machine 100 described in this invention. Furthermore, it reduces the number of guide ceramic elements arranged between the deformation heating box 20 and the cooling device 23. The yarn S enters the cooling device 23 directly from the deformation heating box 20 via a deflecting guide 61, reducing the contact points with the guide ceramic elements during the conveying path, reducing the number of times the yarn S contacts the guide ceramic elements, lowering the risk of the yarn S becoming fuzzy or even breaking due to excessive friction, and reducing tension fluctuations.

[0079] In some examples, the steering guide 61 may be made of a high-hardness, low-friction ceramic (e.g., zirconia ceramic) to reduce the risk of wear on the wire S.

[0080] In some examples, the parameter Figure 1As shown, the height of the turning guide 61 relative to the main frame 10 is adjustable to adjust the wrapping angle b. The turning guide 61 is rotatably supported on a support rod 62 connected to the main frame 10. During the movement of the wire S, the turning guide 61 can reduce the frictional resistance through the rotating action, thereby reducing the abrasion of the wire S.

[0081] The turning guide 61 can also be fixedly connected to the support rod 62. The surface of the turning guide 61 is coated with a self-lubricating material, such as polytetrafluoroethylene (PTFE), to reduce the friction during the transportation of the wire S, thereby reducing the abrasion of the wire S.

[0082] When the height of the turning guide 61 is reduced, the wrapping angle b is increased, the length of the arc formed by the contact between the wire S and the turning guide 61 is reduced, the friction is reduced, the supporting force of the turning guide 61 on the wire S is insufficient, and the tension of the wire S is reduced, which is prone to relaxation or drift, and the wire S is prone to swing during high-speed operation. When the height of the turning guide 61 is increased, the wrapping angle b is reduced, the length of the arc formed by the contact between the wire S and the turning guide 61 is increased, the friction is increased, the sliding resistance between the turning guide 61 and the wire S is increased, and excessive friction can cause the wire S to be prone to abrasion during high-speed operation, which can cause fuzzing or even breakage. Therefore, by adjusting the height of the turning guide 61 to accurately control the wrapping angle b, the wrapping angle b is always kept within 80°-100°. The length of the arc formed by the contact between the wire S and the turning guide 61 is moderate, the friction between the wire S and the turning guide 61 is sufficient to maintain the stable tension of the wire S, and the tension fluctuation is reduced. The swing of the wire S during high-speed operation is prevented. By adjusting the wrapping angle b, the bending radius of the wire S at the turning guide 61 is moderate, and damage to the wire S caused by excessive bending or stretching is avoided.

[0083] In some examples, the height position of the support rod 62 on the main frame 10 can be adjusted by a lifting device such as an electric lifting platform (not shown) to automatically adjust the height of the turning guide 61 relative to the main frame 10 and synchronously adjust the wrapping angle b. Alternatively, the height position of the turning guide 61 on the support rod 62 can be manually adjusted by hand. For example, a waist-shaped hole (not shown) is formed vertically on the support rod 62, and the turning guide 61 moves up and down within a certain range through the waist-shaped hole; or a plurality of circular positioning holes are formed vertically on the support rod 62, and the height of the turning guide 61 is adjusted in segments by selecting different hole positions to adjust the wrapping angle b between 80° and 100°. The specific structure or driving form of the height adjustment of the turning guide 61 is not limited in the present application.

[0084] In some examples, the wire S is guided by the turning guide 61 to form a plurality of turns, and the wire S is guided by the turning guide 61 to form a plurality of turns. Figure 1As shown, the contact between the yarn S and the turning guide 61 forms a yarn conveying highest point, which is above the operation channel 50 and between the deformation heat box 20 and the cooling device 23. The contact between the yarn S and the turning guide 61 forms a more symmetrical bending shape, which evenly distributes the tension along the arc formed by the contact between the yarn S and the turning guide 61, reduces tension fluctuations, and reduces the risk of slack when the yarn S runs at high speed. By keeping the wrapping angle b between 80° and 100°, the position of the highest point ensures that the length of the contact arc between the yarn S and the turning guide 61 is moderate, and the friction provides sufficient support to prevent swinging without causing damage to the yarn S due to excessive friction. In combination Figure 9 As shown, in various embodiments of the present application, the yarn conveying highest point formed by the contact between the yarn S and the turning guide 61 is the tangent point 611 formed by the tangent line 610 of the turning guide 61 and the tangent line 610 is tangent to the turning guide 61 and parallel to the horizontal plane (i.e., the ground 300) in the pre-treatment zone. The tangent point 611 is the aforementioned yarn conveying highest point. The maximum yarn conveying height H1 is the vertical distance between the tangent point 611 and the ground 300. Figure 1 The turning guide 61 supported by the support rod 62 is only a specific implementation of the turning guide 61 being movably connected to the main frame 10. The tangent point 611 is located between the deformation heat box 20 and the cooling device 23 and above the operation channel 50. The turning guide 61 can be supported by the support rod 62'. The maximum height H2 of the equipment formed by the elasticizer 100 is the sum of the aforementioned maximum yarn conveying height H1 and the embedding depth H3 of the yarn S into the turning guide 61, which reduces the overall height of the elasticizer 100. The embedding depth H3 of the yarn S into the turning guide 61 is the vertical distance between the vertical plane 200 where the highest point of the turning guide 61 is located and the tangent line 610.

[0085] In some examples, the elasticizer 100 further includes a yarn guide 60, which is movably connected to the main frame 10 and is located between the deformation heat box 20 and the cooling device 23. Figure 1 The yarn guide 60 is movably connected to the main frame 10 and is located between the deformation heat box 20 and the cooling device 23. Figure 5 As shown, the cooling device 23 includes a cooling rail 231 and metal heat sinks 232 attached to the outer surface of the cooling rail 231, and the length of the cooling rail 231 is 60-90 cm. The cooling rail 231 forms a V-shaped opening 121, and the bottom of the cooling rail 231 forms a yarn channel 2312 for the yarn to pass through. In some examples, the metal heat sinks 232 are made of heat-conductive materials (e.g., stainless steel, copper, or aluminum). By attaching the metal heat sinks 232 to the outer wall of the cooling rail 231, the cooling rail 231 continuously absorbs the heat of the yarn when cooling the yarn, and the metal heat sinks 232 can quickly conduct the heat transferred by the yarn to the surface of the metal heat sinks 232, accelerating heat dissipation and improving the heat dissipation efficiency of the cooling rail 231 to quickly cool the yarn. In actual use, the V-shaped opening 121 of the cooling device 23 is arranged towards the ground 300.

[0086] In some examples, the length of the deformation heat box 20 is 1.2-1.3 m, and the heating temperature of the deformation heat box 20 is 180-250°C. The length of the heat box of the prior art large elasticizer is generally more than 1.5 m, and the large volume of the heat box leads to high heating energy consumption. The present application shortens the length of the deformation heat box 20, so that the length L of the deformation heat box 20 is 1.2-1.3 m, which can reduce the production cost and space occupation of the deformation heat box 20, and reduce the volume, further reduce the space occupation above the first cross beam 111, and reduce the height of the elasticizer 100. Moreover, due to the reduction of the length and volume of the deformation heat box 20, the biphenyl vapor stroke in the deformation heat box 20 is also shortened, so as to reduce the heat loss of the biphenyl vapor due to the long stroke in the deformation heat box 20. Moreover, the temperature gradient in the deformation heat box 20 with shorter length L is smaller, the heating area is concentrated, the heating effect on the yarn S is more uniform, and the heating time can be shortened to adapt to the subsequent false twist deformation processing.

[0087] The disclosed elasticizer 100 can be used to process yarns of different deniers (unit: denier, English abbreviation D). Tests show that when the elasticizer 100 of the present application is used to process yarns (polyester yarns) of 20D / 24F, 75D / 72F, 100D / 72F, 150D / 48F, 150D / 288F, 200D / 288F, or 20D / 7F (nylon yarns), the maximum speed can reach 950 m / min. The F value represents the number of strands (i.e., the number of filaments) of the polyester yarn or nylon yarn; for example, 20D / 24F means that the polyester yarn with a denier of 20D is composed of 24 strands of filaments.

[0088] In some examples, the deformation heat box 20 includes a plurality of heating tracks 204 arranged in the box body 203, a plurality of grooves 211 arranged in the box body 203 for accommodating the heating tracks 204, and a smoke exhaust pipe 30 arranged on the top of the box body 203 and communicating with the grooves 211. Figure 1 With Figure 2 And Figure 6 As shown in the figure, the deformation heat box 20 includes a box body 203, a plurality of heating tracks 204 arranged in the box body 203, a plurality of grooves 211 arranged in the box body 203 for accommodating the heating tracks 204, and a smoke exhaust pipe 30 arranged on the top of the box body 203 and communicating with the grooves 211. The elasticizer 100 further includes a heat box door 205 and a handle 206 arranged at the bottom of the heat box door 205. The handle 206 is configured so that the operator can touch and operate the handle 206 without the aid of auxiliary tools (such as ladders, etc.). Specifically, the deformation heat box 20 is a contact type heat box, and when the yarn S passes through the deformation heat box 20, the yarn S is always in contact with the heating tracks 204, thereby improving the heating uniformity of the deformation heat box 20 on the yarn S, and providing a guarantee for the dyeing uniformity of the yarn.

[0089] The heat box of the prior art large elasticizer needs to be provided with smoke exhaust pipes on the upper and lower parts due to the large volume and large amount of smoke, and the heat box is installed at a high position, so that a long handle part is needed to open and close the heat box door, resulting in a complex structure and high production cost.

[0090] The deformation heat box 20 of the present application is provided with an exhaust pipe 30 at the top of the box body 203, which communicates with the channel 211 where the heat track 204 is located, so as to simplify the exhaust structure. Since the length of the deformation heat box 20 is shortened to 1.2-1.3 m, the travel distance of the oil fume in the channel 211 is shortened, and the amount of smoke is also reduced accordingly, so that the exhaust demand can be met by the exhaust pipe 30 at the top of the deformation heat box 20. At the same time, the oil fume rises fast in the deformation heat box 20, and the exhaust pipe 30 at the top can quickly exhaust the exhaust gas. After the installation position of the deformation heat box 20 is lowered, the maintenance personnel do not need to stand on tiptoe or use long tools to directly operate the handle 206 at the bottom of the deformation heat box 20 to open and close the heat box door 205. For example, Figure 6 The rectangular dashed line shows the opened heat box door 205', as shown in Figure 6 The circular dashed line shows the handle 206' on the heat box door 205'. After the maintenance personnel open the heat box door 205 through the handle 206, the heat track 204 in the box body 203 is exposed to the operation channel 50, and the maintenance personnel can stand on the ground 300 and perform maintenance and cleaning on the deformation heat box 20 in the operation channel 50, thereby improving the maintenance efficiency. By omitting the exhaust pipe at the bottom of the heat box and reducing the length of the handle 206, the structure of the deformation heat box 20 can be simplified to reduce the production cost of the deformation heat box 20.

[0091] In some examples, referring to Figure 1 to Figure 3 As shown, the support assembly 11 further comprises a second cross beam 112 vertically spaced below the first cross beam 111; the out-silk end 202 is supported by a first fixing member 12 connecting the first cross beam 111, and the in-silk end 201 is supported by a second fixing member 13 connecting the side frame 102 and / or the second cross beam 112. The two ends of the second cross beam 112 along the transverse direction are respectively fixed to the center frame 101 and the side frame 102. The second cross beam 112 is located below the first cross beam 111. The in-silk end 201 of the deformation heat box 20 can be connected to the side frame 102 or the second cross beam 112, and both connection modes are located at a lower position on the main frame 10, so as to provide low-position support for the deformation heat box 20, thereby lowering the overall installation position of the deformation heat box 20. The first cross beam 111 and the second cross beam 112 jointly constitute a transverse support structure, which can enhance the structural strength of the main frame 10 and improve the stability of the support for the deformation heat box 20.

[0092] In some examples, referring to Figure 1 to Figure 3 As shown, the two side walls of the deformation heat box 20 along the first direction protrude outward to form a fixing rod 207, and the first fixing member 12 is configured with a groove 122 having an opening 121 for the fixing rod 207 to be inserted into; the second fixing member 13 extends towards the in-silk end 201 of the deformation heat box 20 to form a supporting plate 131, which abuts against the bottom end side wall 208 of the deformation heat box 20 along the inclined direction thereof.

[0093] During installation of the deformation oven 20, the fixing rods 207 of the two side walls of the deformation oven 20 are aligned with the grooves 122 on the first fixing member 12, and the fixing rods 207 are embedded into the grooves 122 to preliminarily fix the position of the wire outlet end 202 of the deformation oven 20. By adjusting the position of the second fixing member 13 on the second cross beam 112 or the side frame 102, the supporting plate 131 can abut against the bottom end side wall 208 of the deformation oven 20, and then the supporting plate 131 is connected with the bottom end side wall 208 of the deformation oven 20 by bolts or other detachable ways, so as to provide vertical supporting force for the deformation oven 20, and make the inclination of the deformation oven 20 meet the set angle a. The first fixing member 12 and the second fixing member 13 jointly form a mixed supporting structure for horizontally limiting the top of the deformation oven 20 and vertically supporting the bottom of the deformation oven 20, so as to ensure the stability of the installation of the deformation oven 20.

[0094] In practice, the texturing machine 100 is preferably combined into a compound machine to obtain a high density of workstations in the factory building. The texturing machine 100 of the present application is particularly suitable for use as a compound machine. In this regard, Figure 8 An example embodiment is shown in which the main frame 10 and the main frame 10' are placed directly against each other. The separation between the main frame 10 and the main frame 10' forms a mirror symmetry axis P about which the two halves of the machine 70.1 and 70.2 are arranged in mirror symmetry. The right half of the machine 70.1 has the same design as the example embodiment according to Figure 1 The left half of the machine 70.2 is arranged in mirror symmetry with respect to the right half of the machine 70.1.

[0095] In some examples, the Figure 7 As shown, the yarn S forms an angle c with the axis Q of the false twist device 24 when entering the first yarn segment S1 formed by the false twist device 24 from the cooling device 23. The angle c can be 0° or greater than or equal to 1° and less than or equal to 30°. The angle c is understood as the entry angle of the yarn S after cooling into the false twist device 24.

[0096] The entering angle of the yarn self-cooling device in the prior art into the false twist device is too large (for example, greater than 30°). The larger entering angle forces the yarn to bend at the entrance of the false twist device, which causes excessive stress inside the yarn fibers, especially at high yarn running speed, which easily causes yarn abrasion, resulting in fuzzing, and even breakage. At the same time, the larger entering angle changes the normal contact state of the yarn with the false twist disc in the false twist device, and the yarn is more likely to contact the edge of the false twist disc in a "collision" or "scraping" or "inclined cutting" manner rather than an ideal "wrapping" state. This non-ideal contact causes local friction between the edge of the false twist disc and the yarn, which not only accelerates the wear of the false twist disc itself, but also seriously scratches or abrades the surface of the yarn. The scratched yarn not only has reduced strength, but also is prone to dyeing spots or stripes due to surface structure damage during subsequent dyeing. At the same time, the larger entering angle increases the twist transmission resistance of the false twist device to the yarn, making it impossible for the yarn to obtain sufficient twist or the obtained twist to be unstable, which easily produces dead yarn and reduces the elasticity of the finished yarn.

[0097] The applicant surprisingly found that by setting the included angle c to 0°, or greater than or equal to 1° and less than or equal to 30°, and especially when the included angle c is set to 25°, the smaller entering angle can reduce the bending degree of the yarn S at the entrance of the false twist device 24, avoid excessive bending, and make the yarn S contact the false twist disc in a smoother and more natural path, reducing the bending stress borne by the fibers inside. The yarn S can contact the surface of the false twist disc at an ideal angle and pressure, reducing abnormal friction such as "scraping", reducing the risk of yarn S abrasion leading to fuzzing or breakage, and prolonging the service life of the yarn S. At the same time, the smaller entering angle can reduce the twist transmission resistance of the false twist device 24 to the yarn S, making the yarn S obtain sufficient and stable twist, avoiding the production of dead yarn, and ensuring the elasticity of the finished yarn. The yarn S enters the false twist device 24 in a smooth path, making the tension at the entrance and exit of the false twist device 24 more easily balanced, reducing tension fluctuations, making the running trajectory of the yarn S more stable, reducing the risk of yarn S shaking, relaxing, winding, or breaking near the false twist device 24, and improving production efficiency.

[0098] In addition, the false twist device 24 in the present application is arranged on the center support 101, and the cooling device 23 is arranged obliquely on the top of the main rack 10. By setting the included angle c to 25°, the cooling device 23 can be prevented from having an excessively large oblique angle, thereby avoiding the cooling device 23 from occupying too much vertical space due to an excessively large oblique angle, and avoiding an increase in the height of the equipment.
