Description

Technical Field

[0001] This application relates to the field of chemical fiber production technology, and in particular to a fiber splitting structure for winding green heads. Background Technology

[0002] As a key step in the chemical fiber production process, the winding start-up is used to guide the yarn to the winding machine and start the winding operation. It is not only related to the smooth start of the production process, but also plays an important role in the re-winding of broken yarn.

[0003] During the filament raising process, workers simultaneously use a suction gun to stretch the filaments to the winding shaft. Due to the uneven tension between the split filaments and the main filament, direct merging would cause localized stretching or loosening of the filaments, affecting the uniformity and strength of the final product. Therefore, during the pulling process, the filament raising head and the main filament need to be separated until the filament raising head is connected to the winding roller of the winding machine. After adjusting the tension of the filament raising head, it is then placed into the filament path of the main filament for filament merging.

[0004] However, due to the long yarn path, which involves sequentially passing through a guide device, a feeding device, a pretreatment device, a guiding and collecting device, and finally connecting to the winding roller of the winding machine, the yarn at the front end may become entangled with the main yarn when the operator stretches the yarn to the middle and later stages. If multiple operators are needed to support the yarn in the middle during the stretching process, it would require a significant amount of manpower. Therefore, a structure is needed to assist in connecting the yarn head to the winding machine. Utility Model Content

[0005] This application provides a filament splitting structure for winding starters, which reduces the filaments from merging with the main filament during the stretching process and avoids wasting manpower.

[0006] The present application provides a wire splitting structure for winding green heads, which adopts the following technical solution:

[0007] A filament splitting structure for winding a raw head, installed in the filament path, includes an installation shaft, a spacer shaft installed on the installation shaft, and two main shafts. There are gaps between the spacer shaft and the two main shafts, forming a main filament path and a filament splitting path.

[0008] By adopting the above technical solution, the gap between the spacer shaft and the two main shafts forms the main filament path and the branch filament path, which can effectively realize the separation of the main filament and the branch filament. That is, the main filament is placed in the main filament path, and then placed into the branch filament path during the stretching process of the filament head, which plays the role of separating the main filament and the filament head, and can support the main filament and the filament head located in the filament path, so as to avoid the branch filament from merging with the main filament and entanglement with the main filament during the stretching process.

[0009] Furthermore, the device allows one worker to independently start the yarn, avoiding the inconvenience of traditional manual operation, improving the efficiency and stability of the yarn-starting operation, and reducing the labor intensity of the workers.

[0010] Optionally, the mounting shaft is equipped with a mounting base, and the mounting base is fixed with a support shaft for abutting against the bottom of the wire.

[0011] By adopting the above technical solution, the support shaft can contact the bottom of the main wire during the winding process, providing stable support for the main wire, thereby improving the stability of the main wire during movement, reducing deviation caused by vibration or external force, and ensuring the smooth progress of the head-growing operation.

[0012] Optionally, the mounting base has a movable hole, which is fitted onto the outer wall of the mounting base; the mounting shaft is provided with a gear, and the mounting base has a toothed groove for the gear to be inserted.

[0013] By adopting the above technical solution, the gear and tooth groove can be matched to fix the mounting base. When the gear is disengaged from the tooth groove, the mounting base can rotate freely, thereby adjusting the angle of the support shaft to meet the support requirements of the main wire at different heights.

[0014] Optionally, the mounting shaft is provided with a positioning plate, and a spring is provided between the positioning plate and the mounting base. The spring force is used to drive the mounting base to move toward one side of the gear.

[0015] By adopting the above technical solution, the spring between the positioning plate and the mounting base can use its elastic force to keep the gear within the tooth groove, thereby achieving a stable connection between the mounting base and the mounting shaft. This design effectively avoids the problem of the mounting base loosening due to vibration or external force during the wire splitting process, ensuring the reliability of the wire splitting structure.

[0016] Optionally, the separator shaft is slidably mounted on the mounting shaft, and the separator shaft is fixed to the mounting shaft by a fixing component.

[0017] By adopting the above technical solution, the sliding connection between the spacer shaft and the mounting shaft allows for adjustment of the distance between the spacer shaft and the main shaft, thereby ensuring that both sides of the main wire can stably abut against the spacer shaft and the main shaft on both sides of the main wire path. This structure effectively improves the stability of the winding process and prevents the main wire from sliding left and right within the main wire path.

[0018] Optionally, the fixing component includes a positioning bolt, an mounting plate is installed at one end of the spacer shaft, the mounting plate has a mounting hole, the mounting hole of the mounting plate is sleeved on the outer wall of the mounting shaft; the mounting plate has a threaded hole communicating with the mounting hole, and the positioning bolt is installed in the threaded hole and used to abut against the outer wall of the mounting shaft.

[0019] By adopting the above technical solution, the mounting holes on the mounting plate are fitted onto the outer wall of the mounting shaft, ensuring the stability of the spacer shaft's position. Simultaneously, the engagement of the threaded holes and the positioning bolts allows the positioning bolts to abut against the outer wall of the mounting shaft, thus achieving a secure fixation of the spacer shaft. This structure not only facilitates adjustment of the spacer shaft's position but also effectively prevents the spacer shaft from loosening during operation.

[0020] Optionally, the positioning bolt is provided with a rubber layer for abutting against the outer wall of the mounting shaft.

[0021] By adopting the above technical solution, the friction force can be effectively increased, thereby improving the stability of the spacer shaft during fixation.

[0022] Optionally, the fixing assembly includes two nuts, the outer wall of the mounting shaft has a threaded portion for threaded engagement with the nuts, and the spacer shaft is clamped between the two nuts.

[0023] By adopting the above technical solution, the spacer shaft can be securely fixed by clamping with two nuts, preventing loosening during winding. The threaded engagement between the nuts and the outer wall of the mounting shaft makes the fixing method simple and reliable, facilitating quick installation and disassembly.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting a separator shaft, the gap between the separator shaft and the two main shafts forms the main wire path and the branch wire path, which can effectively separate the main wire and the branch wire, and avoid the branch wire from merging with the main wire and getting tangled with the main wire during the stretching process. This improves the efficiency and stability of the head-forming operation, while reducing the labor intensity of the workers.

[0026] 2. By sliding the separator shaft to the mounting shaft, the distance between the separator shaft and the main shaft can be adjusted, thereby ensuring that the two sides of the main wire can stably abut against the separator shaft and the main shaft on both sides of the main wire path, preventing the main wire from sliding left and right in the main wire path.

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses a filament splitting structure for winding a green head.

[0036] Reference Figure 1 and Figure 2 A wire splitting structure for winding a green head is installed on the wire path and includes a mounting shaft 1, a wire separator shaft 2 and two main shafts 3. One end of the mounting shaft 1 is threadedly connected to the equipment on the wire path. In this embodiment, the mounting shaft 1 is disposed on the guide bar device 6 of the wire path.

[0037] Reference Figure 2 The two main shafts 3 and the partition shaft 2 are all installed on the mounting shaft 1, and the partition shaft 2 is located between the two main shafts 3. There is a gap between the partition shaft 2 and the two main shafts 3, forming a main wire channel 11 and a branch wire channel 12, so as to achieve the function of separating the main wire and the branch wire.

[0038] Both the spacer shaft 2 and the main shaft 3 have a smooth coating on their outer walls. The smooth coating can reduce the friction between the filament bundle and the main shaft 3 and the spacer shaft 2, and reduce the wear of the filament bundle.

[0039] A mounting plate 21 is provided at one end of the spacer shaft 2. The mounting plate 21 has a mounting hole 22, which is fitted onto the outer wall of the mounting shaft 1. By changing the contact position between the mounting hole 22 and the mounting shaft 1, the position of the spacer shaft 2 can be changed. The spacer shaft 2 is fixed to the mounting plate 21 by the fixing component 4. The sliding connection design between the spacer shaft 2 and the mounting shaft 1 allows adjustment of the distance between the spacer shaft 2 and the main shaft 3, thereby ensuring that both sides of the main wire can stably abut against the spacer shaft 2 and the main shaft 3 on both sides of the main wire path 11, preventing the main wire from sliding left and right within the main wire path 11.

[0040] Reference Figure 3In this embodiment, the fixing component 4 includes a positioning bolt 41 and a rubber layer 42, with the rubber layer 42 disposed at one end of the positioning bolt 41. The outer wall of the mounting plate 21 has a bolt hole communicating with the mounting hole 22. The positioning bolt 41 passes through the threaded hole 23 to abut against the rubber layer 42. The cooperation between the threaded hole 23 and the positioning bolt 41 allows the positioning bolt 41 to abut against the outer wall of the mounting shaft 1, thereby achieving a firm fixation of the wire separator shaft 2. Furthermore, the rubber layer 42 increases the friction between the positioning bolt 41 and the outer wall of the mounting shaft 1.

[0041] The main spindle 3 is connected to the mounting shaft 1 via a connecting plate 31, and the connecting plate 31 is fixed to the mounting shaft 1 via a positioning component. In this embodiment, the positioning component and the fixing component 4 have the same structure, so they will not be described in detail here.

[0042] Reference Figure 4 The mounting shaft 1 is equipped with a mounting base 5. The mounting shaft 1 has a movable hole that fits onto the outer wall of the mounting shaft 1. The mounting base 5 is equipped with a support shaft 51. The extension direction of the support shaft 51 is perpendicular to the traction direction of the main wire. The support shaft 51 is used to abut against the bottom of the main wire to provide stable support force for the main wire, thereby improving the stability of the main wire during movement.

[0043] The mounting shaft 1 is equipped with a gear 52, which is located on the side of the mounting base 5 away from the guide bar device 6. The mounting base 5 has a toothed groove 53 for engaging with the gear 52. When the gear engages with the toothed groove, the mounting base 5 is prevented from rotating freely. When the toothed groove 53 of the mounting base 5 disengages from the engagement with the gear 52, the mounting base 5 can rotate freely, thereby adjusting the angle of the support shaft 51 to meet the support requirements of the main wire at different heights and preventing the main wire and the wire tip from contacting the mounting plate of the mounting shaft 1.

[0044] A positioning plate 54 is provided during installation. The positioning plate 54 is located on the side of the mounting base 5 near the guide bar device 6. A spring 55 is sleeved on the outer wall of the mounting shaft 1. The two ends of the spring 55 abut against the mounting base 5 and the positioning plate 54 respectively. The elastic force of the spring 55 is used to drive the mounting base 5 to move towards the side of the gear 52 so that the gear 52 is normally inserted into the tooth groove 53. This increases the stability of the mounting base 5 fixed to the mounting shaft 1.

[0045] The implementation principle of Embodiment 1 of this application is as follows:

[0046] The gap between the spacer shaft 2 and the two main shafts 3 forms the main yarn path 11 and the branch yarn path 12, which can effectively separate the main yarn and the branch yarn. That is, the main yarn is placed in the main yarn path 11, and then placed into the branch yarn path 12 during the stretching process of the yarn head, which plays the role of separating the main yarn and the yarn head; and can support the main yarn and the yarn head located in the yarn path, so as to prevent the branch yarn from merging with the main yarn and entangled with the main yarn during the stretching process, thus maintaining product quality.

[0047] Furthermore, the device allows a single worker to independently stretch the filament head, avoiding the inconvenience of traditional manual operation, improving the efficiency and stability of the head-stretching operation, and reducing the labor intensity of the workers.

[0048] Example 2:

[0049] This application discloses a filament splitting structure for winding a green head.

[0050] Reference Figure 5 The difference between Embodiment 2 and Embodiment 1 is that the fixing component 4 includes two nuts 43, the outer wall of the mounting shaft 1 is provided with a threaded part for cooperating with the nuts 43, and the mounting plate 21 is clamped between the two nuts 43.

[0051] The implementation principle of Embodiment 2 of this application is as follows:

[0052] The spacer shaft 2 can be securely fixed by clamping with two nuts 43, preventing loosening during winding. The threaded engagement between the nuts 43 and the outer wall of the mounting shaft 1 makes the fixing method simple and reliable, facilitating quick installation and disassembly.

[0053] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
