Description

Technical Field

[0001] This application relates to the field of textile technology, and more particularly to a fiber traction device. Background Technology

[0002] In the drafting unit of a drawing frame, a pressure bar is widely used. Its function is to extend the friction boundary of the drafting zone towards the jaws formed by the first roller and the first roller tipper, allowing for better fiber control. Current technology mounts the pressure bar on the second roller bearing housing or the second roller tipper bearing housing, establishing a fixed positional relationship between the pressure bar and the second roller and the second roller tipper in the main drafting zone. However, when processing fibers of different lengths, the distance between the drafting rollers needs to be adjusted. In the design of the drawing frame drafting unit, the first roller bearing housing is fixed; therefore, adjusting the roller distance involves moving the positions of the second and third rollers. Conventionally, the distance between the first and second rollers is called the main drafting zone spacing, and the distance between the second and third rollers is called the back drafting zone spacing. Because the pressure bar is currently mounted on the second roller bearing housing or the second roller tipper bearing housing, the relative position of the first roller and the pressure bar will change as the second roller moves when the main drafting zone spacing is adjusted.

[0003] In recent years, due to increased emphasis on environmental protection, the use of staple fibers has increased in some yarn varieties. When processing raw materials with a high proportion of staple fibers, controlling their movement has become a key technological focus. This requires bringing the pressure bar closer to the gripping line formed by the first roller and its guide roller. Using existing technology, to achieve good control over these staple fibers, the distance between the first and second rollers needs to be very small to bring the pressure bar closer to this gripping line. However, a large proportion of the spinning raw material also contains normal-length fibers. If the main drafting zone spacing is too small, the normal-length fibers cannot be effectively drafted, ultimately affecting yarn quality. To solve the problem of effective drafting of normal-length fibers, the existing solution is to increase the roller spacing in the main drafting zone. However, because the pressure bar moves with the second roller bearing housing in existing technology, increasing the roller spacing in the main drafting zone also moves the pressure bar further away from the first roller. This causes the pressure bar to lose its effective control over the staple fibers. Summary of the Invention

Detailed Implementation

[0041] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0042] like Figures 1 to 3 As shown in the embodiment of this application, a fiber traction device is proposed, comprising: a first roller assembly, a second roller assembly, and a third roller assembly arranged sequentially along the traction direction; a bearing seat guide rail 4, on which the second roller assembly and the third roller assembly are slidably disposed; and a pressure bar assembly connected to the first roller assembly.

[0043] The fiber traction device provided in this embodiment includes a first roller assembly, a second roller assembly, a third roller assembly, a bearing seat guide rail 4, and a pressure bar assembly. The installation positions of the second and third roller assemblies can be adjusted via the bearing seat guide rail 4. When adjusting the main drafting zone spacing, the main drafting zone spacing can be set as needed to effectively draft fibers of normal length in the raw material. The pressure bar assembly extends the friction boundary of the main drafting zone towards the jaws formed by the first roller 5 and the first traction roller 9 of the first roller assembly. The fiber traction device provided in this embodiment transfers the mounting base of the pressure bar assembly from the second roller assembly to the first roller assembly. After this adjustment, the pressure bar assembly and the first roller assembly form a fixed positional relationship, allowing the pressure bar assembly to be closer to the gripping line of the first roller assembly, thus providing good control over short fibers. For fibers of normal length in the raw material, when it is necessary to increase the main drafting zone spacing during processing, the installation positions of the second and third roller assemblies can be set as needed to adjust the spacing between the main and rear drafting zones, ensuring effective drafting of fibers of normal length in the raw material. The fiber traction device provided in this application embodiment effectively controls short fibers while also effectively drafting fibers of normal length.

[0044] It is understandable that the surface distance between the first roller and the second roller is called the main drafting zone distance, and the surface distance between the second roller and the third roller assembly is called the rear drafting zone distance. The main drafting zone distance and the rear drafting zone distance can be adjusted by moving the second roller assembly and the third roller assembly.

[0045] In one feasible implementation, the first roller assembly includes: a first bearing housing 1; a first roller 5 connected to the first bearing housing 1; a guide roller 8 disposed on one side of the first roller 5; and a first traction roller 9 disposed on one side of the first roller 5, and positioned close to the second roller assembly relative to the guide roller 8.

[0046] In this technical solution, the structure of the first roller assembly is further provided. The first roller assembly may include a first bearing seat 1, a first roller 5, a guide roller 8, and a first traction roller 9. The first bearing seat 1 facilitates the rotation of the first roller 5. At the same time, the guide roller 8 and the first traction roller 9 can also rotate around their respective axes. Based on this, the first roller assembly can guide and traction the fibers.

[0047] like Figures 1 to 3 As shown, where Figures 1 to 3In the diagram, the second roller 6 and the second traction roller 10, indicated by the dotted line, represent the positions of the second roller assembly when the second roller assembly is adjusted to the minimum main drafting zone spacing. In one feasible embodiment, the pressure bar assembly includes: a pressure bar support 13 connected to the first roller assembly; and a pressure bar 12 connected to the pressure bar support 13.

[0048] In this technical solution, the structural composition of the pressure bar assembly is further provided. The pressure bar assembly may include a pressure bar support 13 and a pressure bar 12. Based on this, the installation, disassembly and maintenance of the pressure bar 12 are facilitated by the setting of the pressure bar support 13. The setting of the pressure bar 12 can extend the friction boundary of the stretching zone to the jaws formed by the first roller 5 and the first traction roller 9.

[0049] like Figure 1 As shown, in one feasible embodiment, the pressure bar assembly further includes: a rotating shaft 15, the rotating shaft 15 being fixed to the first bearing seat 1, and the pressure bar support 13 being hinged to the rotating shaft 15.

[0050] This technical solution provides a first method for fixing the pressure rod assembly. The pressure rod assembly may include a rotating shaft 15, a pressure rod support 13, and a pressure rod 12. The rotating shaft 15 of the pressure rod support 13 is fixed to a first bearing seat 1. The pressure rod 12 is mounted on the pressure rod support 13. The pressure rod support 13 is hinged to the rotating shaft 15, which facilitates the assembly of the pressure rod 12 and the operation of stopping the vehicle.

[0051] like Figure 2 As shown, in one feasible embodiment, the pressure bar assembly further includes a guide groove 14, which is formed on the first bearing seat 1, and the pressure bar support 13 is disposed in the guide groove 14.

[0052] This technical solution provides a second method for fixing the pressure rod assembly, which may include a guide groove 14 machined on the first bearing seat 1. During assembly, the pressure rod 12 can be mounted on the pressure rod support 13, and then the pressure rod support 13 with the pressure rod 12 can be mounted in the guide groove 14 on the first bearing seat 1. This arrangement facilitates the assembly of the pressure rod assembly.

[0053] like Figure 3 As shown, in one feasible embodiment, the pressure bar support 13 is connected to the bearing seat of the first traction roller 9.

[0054] This technical solution provides a third way to fix the pressure bar assembly: the pressure bar support 13 can be installed on the bearing seat of the first traction roller 9, and then the pressure bar 12 can be installed on the pressure bar support 13. During operation, the first traction roller 9 with the pressure bar 12 is installed in the mounting groove of the first traction roller 9. This arrangement allows the overall structure of the traction device to be modularized, resulting in a low failure rate and easy assembly.

[0055] In one feasible implementation, the second roller assembly includes: a second bearing housing 2, which is slidably connected to the bearing housing guide rail 4 and arranged between the first roller assembly and the third roller assembly; and a second roller 6, which is connected to the second bearing housing 2.

[0056] In this technical solution, the structure of the second roller assembly is further provided. The second roller assembly may include a second bearing seat 2 and a second roller 6. The second roller 6 can rotate by the setting of the second bearing seat 2, which facilitates the traction of fibers.

[0057] In one possible implementation, the second roller assembly further includes a second traction roller 10, which is disposed on one side of the second roller 6.

[0058] In this technical solution, the second roller assembly may also include a second traction roller 10. The second traction roller 10 can be used in combination with the second roller 6 to facilitate the traction of fibers.

[0059] In one feasible implementation, the third roller assembly includes: a third bearing housing 3, which is slidably connected to a bearing housing guide rail 4 and arranged on the side of the second roller assembly away from the first roller assembly; and a third roller 7, which is connected to the third bearing housing 3.

[0060] In this technical solution, the structure of the third roller assembly is further provided. The third roller assembly may include a third bearing seat 3 and a third roller 7. The third roller 7 can rotate through the setting of the third bearing seat 3, which facilitates the traction of fibers.

[0061] It is understandable that the sliding connection between the second bearing housing 2 and the third bearing housing 3 and the bearing housing guide rail 4 facilitates the adjustment of the positions of the second roller assembly and the third roller assembly.

[0062] In one feasible embodiment, a first roller mounting groove is formed on the first bearing housing 1, and the guide roller and the first traction roller 9 are disposed within the first roller mounting groove; a second roller mounting groove is formed on the second bearing housing 2, and the second traction roller 10 is disposed within the second roller mounting groove; a third roller mounting groove is formed on the third bearing housing 3, and the third traction roller 11 is disposed within the third roller mounting groove. This facilitates the installation of the guide roller 8, the first traction roller 9, the second traction roller 10, and the third traction roller 11.
