[0029] The present utility model will be described in detail below in conjunction with the embodiments shown in the drawings. It should be noted, however, that these embodiments are not intended to limit the present utility model. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present utility model.
[0030] Refer Figure 1 and Figure 2 , which is a specific embodiment of a yarn conveying system of a false twist texturing machine provided by the present utility model. The wire guiding tube 41 is composed of a wire inlet tube 411, a first wire outlet tube 412, and a second wire outlet tube 413. After two raw filaments a are simultaneously led out from the raw filament frame 4, they can be respectively guided to the first wire guiding device 1a and the second wire guiding device 2a through the wire inlet tube 411 and then through the first wire outlet tube 412 and the second wire outlet tube 413, or they can be simultaneously guided to the first wire guiding device 1a or the second wire guiding device 2a through the first wire outlet tube 412 or the second wire outlet tube 413. When applied to a false twist texturing machine, the above three wire guiding methods can be selected according to actual needs. Moreover, the wire guiding tube 41 is not limited to guiding two raw filaments a, and can also be used to guide one raw filament a. Through the above design, compared with the wire guiding tubes for guiding two raw filaments in the prior art, it has a smaller volume and multiple wire guiding methods, and is suitable for various wire guiding operation scenarios.
[0031] Refer Figure 1 and Figure 2As shown, in this embodiment, the yarn conveying system of the false twist texturing machine (hereinafter simply referred to as the yarn conveying system) includes a frame 10 and a raw yarn creel 4. The frame 10 is provided with a first wire guiding device 1a and a second wire guiding device 2a. After two raw yarns a are led out from the raw yarn creel 4, they are respectively guided to the first wire guiding device 1a and the second wire guiding device 2a by wire guiding tubes 41. The frame 10 is connected to a false twist texturing assembly 3, and the two raw yarns a are respectively introduced into the false twist texturing assembly 3 by the first wire guiding device 1a and the second wire guiding device 2a; the wire guiding tube 41 includes an inlet wire tube 411, a first outlet wire tube 412 and a second outlet wire tube 413. After the two raw yarns a are led out from the raw yarn creel 4, they are guided by the inlet wire tube 411. The first outlet wire tube 412 is coaxially arranged and communicated with the inlet wire tube 411. The second outlet wire tube 413 is communicated with the first outlet wire tube 412 and forms an angle less than or equal to 90°. After the two raw yarns a respectively pass through an inlet wire tube 411, they are then guided to the first wire guiding device 1a and / or the second wire guiding device 2a by the first outlet wire tube 412 and / or the second outlet wire tube 413.
[0032] Refer Figure 1 and Figure 2As shown, the first wire guiding device 1a is installed above the second wire guiding device 2a at the frame 10. The axis of the wire inlet pipe 411 is arranged parallel to the length direction of the frame 10. The second wire outlet pipe 413 is perpendicular to the first wire outlet pipe 412. Two raw filaments a are respectively guided by the first wire outlet pipe 412 and the second wire outlet pipe 413 to the first wire guiding device 1a and the second wire guiding device 2a. It should be noted that a wire guiding pipe 41 is correspondingly provided for each raw filament a. That is, after the two raw filaments a are led out from the raw filament frame a, they are respectively guided by the wire inlet pipe 411 of a wire guiding pipe 41 into the first wire outlet pipe 412 or the second wire outlet pipe 413 communicated with the wire inlet pipe 411. In this embodiment, the two raw filaments a are led out from the raw filament frame 4, and after being respectively guided by a wire inlet pipe 411, one raw filament a is axially guided by the first wire outlet pipe 412 communicated with a wire inlet pipe 411 to the first wire guiding device 1a, and the other raw filament a is guided by the second wire outlet pipe 413 communicated with another wire inlet pipe 411 to the second wire guiding device 2a. Through the design of the first wire outlet pipe 412 and the second wire outlet pipe 413, after the two raw filaments a are respectively led out from a wire inlet pipe 411, only need to select according to actual needs for the two raw filaments a to pass through the first wire outlet pipe 412 or the second wire outlet pipe 413 to guide the raw filaments to the first wire guiding device 1a or the second wire guiding device 2a. Especially through the design of the second wire outlet pipe 413, the second wire outlet pipe 413 only needs to be designed with a smaller length to achieve the purpose of changing the conveying direction of the raw filament a. Compared with the prior art in which the wire guiding pipe has two parallel wire outlet pipes with different heights, the volume, cost and installation difficulty of the wire guiding pipe 41 are significantly reduced, and it has good applicability. It should be noted that the wire guiding pipe 41 in this embodiment can also be applied to a yarn conveying system with a single conveying mode, that is, after a single raw filament a is led out from the raw filament frame 4 and guided by the wire inlet pipe 411, select according to the installation position of the wire guiding device for the raw filament a to pass through the first wire outlet pipe 412 or the second wire outlet pipe 413.
[0033] See Figure 3As shown, it is an implementation of the wire guide tube 41 in the yarn conveying system. The wire inlet tube 411, the first wire outlet tube 412, and the second wire outlet tube 413 are interconnected through an elastic joint 414. The elastic joint 414 has a first interface 414a, a second interface 414b, and a third interface 414c for connecting the wire inlet tube 411, the first wire outlet tube 412, and the second wire outlet tube 413; the elastic joint 414 is selected as a transparent pipe fitting. When the elastic joint 414 is applied to the technical solution where the first wire outlet tube 412 and the second wire outlet tube 413 are perpendicularly arranged in the foregoing implementation, the first interface 414a and the second interface 414b are coaxially arranged, and one end of the wire inlet tube 411 away from the raw yarn frame 4 is connected to the first interface 414a, and the second interface 414b is connected to the first wire outlet tube 412. The third interface 414c is perpendicularly arranged with respect to the first interface 414a and the second interface 414b, and the second wire outlet tube 413 is connected to the third interface 414c. Through this solution, the wire inlet tube 411, the first wire outlet tube 412, and the second wire outlet tube 413 are of a split design. When assembling the above three parts into the whole wire guide tube 41, different lengths of the wire inlet tube 411, the first wire outlet tube 412, and the second wire outlet tube 413 can be selected according to the actual structure of the false twist texturing equipment, and then they can be quickly assembled through the elastic elastic joint 414, further improving the applicability of the wire guide tube 41. Further, the wire inlet tube 411, the first wire outlet tube 412, and the second wire outlet tube 413 are metal conduits (for example, aluminum tubes). By preferably using a transparent pipe fitting for the elastic joint 414, it is possible to observe whether the raw yarn a is blocked, knotted, or wound during the conveying process at the elastic joint 414, so as to clean it in time.
[0034] Since the wire inlet tube 411 needs to guide the raw yarn a from the raw yarn frame 4 to near the first wire guiding device 1a and the second wire guiding device 2a, it has a relatively large length. The material of its aluminum tube or other metal tubes results in a relatively high cost and large weight. If the wire inlet tube 411 is integrally designed with the first wire inlet tube 412 and the second wire inlet tube 413, it will cause a further increase in weight and cost, and the applicability will be reduced. By connecting the above three parts through the elastic joint 414 to form the wire guide tube 411, during actual assembly, the wire inlet tube 411, the first wire outlet tube 412, and the second wire outlet tube can be respectively fixed to the frame 10 through connecting parts such as mounting seats (not shown), and then the elastic joint 414 is sleeved on the ends of the wire inlet tube 411, the first wire outlet tube 412, and the second wire outlet tube 413 to complete the assembly of the entire wire guide tube 41, making the process of installing the wire guide tube 41 onto the frame 10 fast and easy to operate. In this implementation, the elastic joint 414 can be selected from materials such as nylon, silica gel, and rubber.
[0035] Refer to Figure 2As shown, in this embodiment, the first wire guiding device 1a is configured as a clamping conveyor, including two conveying rollers (not labeled), and the two conveying rollers (not labeled) have a clamping and conveying state as shown by Figure 2 the solid line and a released state as shown by Figure 2 the dashed line. The raw wire a led out from the first wire outlet pipe 412 is guided between the two conveying rollers (not labeled), and the two conveying rollers (not labeled) hold the raw wire a in the Figure 2 shown state. The second wire guiding device 2a is configured as a clamping conveyor with the same structure as the first wire guiding device 1a, and another raw wire a led out from the second wire outlet pipe 413 is guided between the two conveying rollers (not labeled) of the second wire guiding device 2a. It should be noted that the first wire guiding device 1a and the second wire guiding device 2a can also be configured as winding conveying devices in this embodiment.
[0036] Refer Figure 2 to the figure. The first wire guiding device 1a has a wire cutting device 11, the second wire guiding device 2a has a wire cutting device 21, the top end of the first wire guiding device 1a is connected to a wire detecting device 13 through a mounting plate 12, and the wire detecting device 13 is electrically connected to the wire cutting device 11 and the wire cutting device 21. A raw wire a transmitted between the two conveying rollers (not labeled) of the first wire guiding device 1a and a raw wire a transmitted between the two conveying rollers (not labeled) of the second wire guiding device 2a pass through the wire detecting device 13. The wire detecting device 13 monitors the states of the two raw wires a guided by the first wire guiding device 1a and the second wire guiding device 2a in real time. When it is found that the raw wire a is broken or damaged, a signal is sent to the wire cutting device 11 or the wire cutting device 21 to cause the wire cutting device 11 or the wire cutting device 21 to cut off the raw wire a to avoid roll entanglement.
[0037] Refer Figure 1 to the figure. The texturing false-twist assembly 3 includes a texturing hot box 31, a first false-twist device 34, and a second false-twist device 35. Two raw wires a are introduced into the texturing hot box 31 by the first wire guiding device 1a and the second wire guiding device 2a and then false-twist deformed by the first false-twist device 34 and the second false-twist device 35; a first cooling device 32 is provided on the processing path between the texturing hot box 31 and the first false-twist device 34, and a second cooling device 33 is provided on the processing path between the texturing hot box 31 and the second false-twist device 35. The texturing hot box 31 is inclined and arranged on the top surface of the frame 10 through a bracket 105, and the bracket 105 is connected to a twist stopping device 101. It should be noted that the bracket 105 also has a transition porcelain part 102 and a first guiding part 103. After passing through the wire detecting device 13, the two raw wires a pass around the twist stopping device 101, the transition porcelain part 102, and the first guiding part 103 and then enter the texturing hot box 31.
[0038] Refer Figure 1As shown, the yarn conveying system further includes a third wire guiding device 5. The third wire guiding device 5 and the first wire guiding device 1a and the second wire guiding device 2a respectively form a stretching area (not marked). Two raw filaments a are led out by the first false twisting device 34 and the second false twisting device 35 and then enter the third wire guiding device 5. It should be noted that in this embodiment, the raw filament a is a pre-drawn yarn (POY), which becomes a drawn textured yarn (DTY) after false twisting deformation and stretching deformation. Therefore, the two raw filaments a are respectively stretched through the stretching area (not marked) formed between the third wire guiding device 5, the first wire guiding device 1a, and the second wire guiding device 2a. Moreover, the third wire guiding device 5 has two conveying rollers that are the same as those of the first conveying device 1a and the second conveying device 2a. Further, the principle of forming a stretching area between the first wire guiding device 1a and the third wire guiding device 5 is that the rotational speed of the two conveying rollers (not marked) of the first wire guiding device 1a is less than the rotational speed of the two conveying rollers (not marked) of the third wire guiding device 5. For example, the rotational speed of the two conveying rollers (not marked) of the first wire guiding device 1a is 1000 r / min, while the rotational speed of the two conveying rollers (not marked) of the third wire guiding device 5 is 1050 r / min. Therefore, there is a speed difference when the raw filament a passes through the first wire guiding device 1a and the third wire guiding device 5. The principle of forming a stretching area between the second wire guiding device 2a and the third wire guiding device 5 is the same as the above, and will not be elaborated here. Through the above process, the stretching action of the two raw filaments a that are heated by the texturing hot box 31, cooled by the first cooling device 32 and the second cooling device 33, and then false twisted by the first false twisting device 34 and the second false twisting device 35 is realized, and the entire guiding, stretching, and deformation actions of the two raw filaments a are completed. It should be noted that the bracket 105 also has a second guiding member 104. After the two raw filaments a pass through the texturing hot box 31, they bypass the second guiding member 104 and are then cooled by the first cooling device 32 and the second cooling device 33.
[0039] Referring to Figure 4 and Figure 5 shown, the yarn conveying system of the false twisting machine designed according to another embodiment disclosed by the present utility model, compared with the foregoing embodiment, is different in that: the first wire guiding device 1b is installed above the second wire guiding device 2b at the frame 10. The axis of the wire inlet pipe 411 is arranged parallel to the length direction of the frame 10. The second wire outlet pipe 413 is perpendicular to the first wire outlet pipe 412. Two raw filaments a respectively pass through a wire inlet pipe 411 and are guided to the first wire guiding device 1b by the first wire outlet pipe 412 that is respectively communicated with the two wire inlet pipes 411
[0040] Specifically refer to Figure 5As shown, when two raw filaments a can be guided by the same wire guiding device, after the two raw filaments a respectively pass through two wire inlet tubes 411, they can then be simultaneously guided by a first wire outlet tube 412 communicating with the two wire inlet tubes 411 to the same first wire guiding device 1b, and then simultaneously guided by the first wire guiding device 1b into the texturing hot box 31. In this embodiment, the second wire guiding device 2b is in a shutdown state. It should be noted that in the solution where the two raw filaments a are respectively guided by one first wire outlet tube 411 in this embodiment, the raw filament a has a smaller diameter. In this embodiment, the wire inlet tube 411, the first wire outlet tube 412, and the third wire outlet tube 413 can also be of a split design and connected through Figure 3 the elastic joint 414 shown, and the specific connection method is the same as the foregoing and will not be elaborated here. In this embodiment, the first wire guiding device 1b and the second wire guiding device 2b can also be selected as winding conveying devices.
[0041] Referring to Figure 6 and Figure 7 As shown, a false twisting texturing machine yarn conveying system designed according to another embodiment disclosed by the present utility model is different from the foregoing embodiment in that: the first wire guiding device 1c is installed above the second wire guiding device 2c at the frame 10, the axis of the wire inlet tube 411 is arranged parallel to the length direction of the frame 10, the second wire outlet tube 413 is perpendicular to the first wire outlet tube 412, and the two raw filaments a respectively pass through one wire inlet tube 411 and are then guided by the second wire outlet tube 413 respectively communicating with the two wire inlet tubes 411 to the second wire guiding device 2c.
[0042] Specifically referring to Figure 7 As shown, when two raw filaments a can be guided by the same wire guiding device, after the two raw filaments a respectively pass through two wire inlet tubes 411, they can then be simultaneously guided by the second wire outlet tube 413 communicating with the two wire inlet tubes 411 to the same second wire guiding device 2c, and then simultaneously guided by the second wire guiding device 2c into the texturing hot box 31. In this embodiment, the first wire guiding device 2c is in a shutdown state. And when the raw filament a has a larger diameter, after being conveyed by the second wire guiding device 2c, the two raw filaments a can pass through the conveying of the first wire guiding device 1c which is arranged above the second wire guiding device 2c and is in a startup state again. In this process, the second wire guiding device 2c and the first wire guiding device 1c can achieve the purpose of preliminarily stretching the raw filament a with a larger diameter (this transmission method is not shown in the drawings). In this embodiment, the wire inlet tube 411, the first wire outlet tube 412, and the third wire outlet tube 413 can also be of a split design and connected through Figure 3 the elastic joint 414 shown, and the specific connection method is the same as the foregoing and will not be elaborated here.
[0043] Referring to Figure 8As shown in the figure, it is a yarn conveying system of a false twist texturing machine designed according to another embodiment disclosed by the present utility model. Compared with the previous embodiment, the difference lies in that the axis of the wire inlet pipe 411 is arranged parallel to the length direction of the frame 10, the top end of the second wire outlet pipe 413a is communicated with the first wire outlet pipe 412, the bottom end of the second wire outlet pipe 413a is inclined towards the direction away from the raw yarn frame 4, and the two raw yarns a respectively pass through a wire inlet pipe 411 and then are guided to the first wire guiding device 1a and / or the second wire guiding device 2a by the first wire outlet pipe 412 and / or the second wire outlet pipe 413a. (In this embodiment, the first wire guiding devices 1a and 2a are the same as those in Figure 2 ). After the two raw yarns a are led out from the raw yarn frame 4 and then guided by the two wire inlet pipes 411, they can be respectively guided to the first wire guiding device 1a and the second wire guiding device 2a by the first wire outlet pipe 412 and the second wire outlet pipe 413a, or can be simultaneously guided to the first wire guiding device 1a by the first wire outlet pipe 412 or simultaneously guided to the second wire guiding device 2b by the second wire outlet pipe 413a. The specific implementation scheme is the same as that in the previous embodiment and will not be elaborated here. In this embodiment, by arranging the second wire outlet pipe 413a obliquely, the distance between the wire outlet ports of the first wire outlet pipe 412 and the second wire outlet pipe 413a is effectively shortened, which is applicable to the situation where the distance between the first wire guiding device 1a and the second wire guiding device 2a is relatively small.
[0044] Refer to Figure 9 As shown in the figure, this embodiment can still use the elastic joint 415 to connect the split wire inlet pipe 411, the first wire outlet pipe 412 and the third wire outlet pipe 413a. At this time, the first interface 415a and the second interface 415b of the elastic joint 415 are still distributed along the same axis, and the included angle between the third interface 415c and the axes of the first interface 415a and the second interface 415b is selected according to the required inclination angle of the second wire outlet pipe 413a. For example, when the included angle between the axis of the first wire outlet pipe 412 and the second wire outlet pipe 413a is 60°, the included angle between the third interface 415c and the axes of the first interface 415a and the second interface 415b is also 60°. The specific method of assembling the wire inlet pipe 411, the first wire outlet pipe 412 and the second wire outlet pipe 413a through the elastic joint 415 is the same as the previous one and will not be elaborated here. Through the above scheme, the purpose of adjusting the angle of the second wire outlet pipe 413a according to actual needs can be achieved, and the applicability of the wire guiding pipe 41 can be further improved.
