[0027] The embodiments of the present application provide a cold hub device and a spinning device, thereby solving the technical problem in the prior art that the cold hub is prone to jumping during use.

[0028] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0029] The spinning device of the present application can not only cool the filament bundle, but also eliminate the internal stress caused by the curling and deformation of the filament bundle. Moreover, by fixedly connecting the rear end cover to the cold hub shaft frame and arranging it opposite to the cold hub, when the cold hub rotates, the rear end cover does not need to rotate with the cold hub, thereby reducing the weight of the rotating part and making the operation of the cold hub more stable. The cold hub device of the present application has a simple structure and a good cooling effect.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] In order to solve the technical problem in the prior art that the cold hub is prone to jumping during use, the present application provides a cold hub device and a spinning device.

[0032] Embodiment 1

[0033] The cold hub device of the prior art includes a cold hub, a front cover and a rear cover fixed at both ends of the cold hub. When in use, the front cover and the rear cover rotate together with the cold hub to complete the curling of the tow. However, it is found that the cold hub is prone to jumping during use. After careful research and countless experiments, the inventor found that the reason for the jumping of the cold hub is that the front cover and the rear cover rotate together with the cold hub, resulting in a large weight of the rotating part, which in turn causes the cold hub to jump.

[0034] After discovering the cause of the vibration of the cold hub, a cold hub device of the present application is proposed to solve the technical problem.

[0035] like Figure 1 and Figure 2 As shown, the cold hub device includes a cold hub 1, a rear end cover 2, a cold hub shaft frame 3, a suction tube 4, a coupling 5, a reduction motor 6, a cooling plate 7, a mounting wall panel 10, and a transmission shaft 11.

[0036] The rear end cover 2 is arranged opposite to the cold hub 1, that is, the rear end cover 2 and the cold hub 1 can rotate relative to each other. A ventilation space is arranged inside the cold hub 1.

[0037] The cooling disc 7 is fixed on the cold hub 1, and mesh holes are provided on the cooling disc 7, which are connected to the ventilation space of the cold hub 1, so that the cooling disc 7 can be used to absorb the filament bundle 12. In this embodiment, the cross section of the cooling disc 7 is U-shaped, which can effectively prevent the wire from getting stuck.

[0038] One end of the transmission shaft 11 passes through the rear end cover 2 and is fixed on the cold hub 1. When the transmission shaft 11 rotates, the cold hub 1 is driven to rotate.

[0039] One end of the cold hub shaft drum frame 3 is fixed on the rear end cover 2, and is sleeved on the transmission shaft 11. When the transmission shaft 11 rotates, the cold hub 1 is driven to rotate relative to the rear end cover 2 and the cold hub shaft drum frame 3. An air suction channel 31 connected to the ventilation space of the cold hub 1 is provided between the cold hub shaft drum frame 3 and the transmission shaft 11. A suction cylinder 4 is provided on the cold hub shaft drum frame 3, and the suction cylinder 4 is connected to the suction fan, and the suction cylinder 4 is connected to the suction channel 31. When the suction fan is working, the heat on the filament bundle 12 enters the ventilation space of the cold hub 1 after passing through the mesh on the cooling disk 7 with the air flow, and then enters the suction channel 31 between the cold hub shaft drum frame 3 and the transmission shaft 11, and is finally extracted from the suction cylinder 4.

[0040] Furthermore, rolling bearings are respectively arranged at both ends of the cold hub shaft frame 3, and the transmission shaft 11 is rotatably fixed in the two rolling bearings.

[0041] The cold hub shaft drum frame 3 is fixed on the mounting wallboard 10 and is used to fix the cold hub device. In other embodiments, the mounting wallboard 10 can also be set as needed. Further, the cold hub shaft drum frame 3 and the cold hub 1 are mounted on the same side of the mounting wallboard 10, and the front end of the transmission shaft 11 is cantilevered and connected to the cold hub 1, so that the front end of the transmission shaft 11 has a small overhang amount and a small deflection deformation. In addition, the rear end cover 2 is fixedly connected to the cold hub shaft drum frame 3 and is arranged opposite to the cold hub 1. When the cold hub 1 rotates, the rear end cover 2 does not need to rotate with the cold hub 1, which can reduce the weight of the rotating part and make the operation of the cold hub 1 more stable.

[0042] One end of the coupling 5 is connected to the reduction motor 6, and the other end is connected to the other end of the transmission shaft 11, which is used to transmit the power of the reduction motor 6 to the transmission shaft 11, drive the transmission shaft 11 to rotate, and thus drive the cold hub 1 to rotate. The cold hub device adopts a reduction motor direct connection method to reduce later maintenance and reduce maintenance costs. In addition, by adopting the reduction motor 6, the rotation speed of the transmission shaft 11 is slow, thereby driving the cold hub 1 to rotate slowly, so that the filament bundle can be adsorbed on the cooling plate 7 in a relaxed state and stay longer, so as to fully eliminate the internal stress caused by the curling deformation of the filament bundle 12.

[0043] The cold hub device further comprises a sealing ring 8 and a windshield 9. The sealing ring 8 is arranged between the rear end cover 2 and the cold hub 1, and is used to close the gap between the rear end cover 2 and the cold hub 1, which can effectively prevent invalid cold wind from entering the cold hub 1, enhance the cooling effect, and reduce energy loss. Further, the cold hub 1 is provided with a sealing ring 8, and the rear end cover 2 is provided with a groove for accommodating the sealing ring 8. Specifically, the sealing ring 8 is arranged on the inner side of the cold hub (1), and the groove is provided on the outer side of the rear end cover (2). Further, the sealing ring 8 is specifically a labyrinth-type sealing ring.

[0044] The windshield 9 is fixed on the rear end cover 2, and is located on the side of the cooling plate 7 where the filament bundle 12 is not adsorbed. When the filament bundle 12 moves to the position of the windshield 9 along with the cold hub 1, the filament bundle 12 is no longer subjected to the negative pressure, and leaves the cooling plate 7 and the cold hub 1. Specifically, in this embodiment, the windshield 9 is a curved plate, and in other embodiments, the windshield 9 can also be set to a flat plate, a curved plate, or the like.

[0045] like Figure 3 As shown, when in use, the filament bundle 12 that has been puffed and curled at high temperature and high pressure by the expander 13 enters the cold hub device, the fan is started, and suction is performed through the suction tube 4, generating negative pressure on the surface of the cooling disk 7 to stably adsorb the filament bundle 12 on the surface of the cooling disk 7. Assuming that the starting point of the filament bundle adsorbed to the cooling disk 7 is the 12 o'clock position on the clock, the end point of the filament bundle 12 on the cooling disk 7 is the 5 o'clock-6 o'clock position on the clock, that is, the angle of the filament bundle 12 on the cooling disk 7 is the 5 o'clock-6 o'clock position on the clock. The reduction motor 6 drives the transmission shaft 11 to rotate through the coupling 5, thereby driving the cold hub 1 to rotate, and the cooling disk 7 rotates with the cold hub 1, thereby continuously cooling the filament bundle passing through the expander 13. After the filament bundle 12 reaches the end point on the cooling disk 7, it is no longer adsorbed on the cooling disk 7, detaches from the cold hub 1, and enters the main network to increase the cohesion of the filament bundle.

[0046] The cold hub device of the present application can not only cool the filament bundle, but also eliminate the internal stress caused by the curling deformation of the filament bundle 12. Moreover, by fixedly connecting the rear end cover 2 to the cold hub shaft frame 3 and arranging it opposite to the cold hub 1, when the cold hub 1 rotates, the rear end cover 2 does not need to rotate with the cold hub 1, thereby reducing the weight of the rotating part and making the operation of the cold hub 1 more stable. The cold hub device of the present application has a simple structure, good cooling effect and stable operation, and solves the technical problem in the prior art that the cold hub is prone to jumping during use.

[0047] The cold hub device of the present application can be used for cooling PP, PET, and PA6 with a density of 1000-3000 detx after expansion, but is not limited thereto.

[0048] The cold hub diameter of the present application adopts a large diameter of 485, which can effectively increase the cooling area, extend the cooling time of the wire bundle, and ensure that the wire bundle is cooled and shaped.

[0049] Embodiment 2

[0050] Based on the same inventive concept, the present application also provides a spinning device, which includes the cold hub device in Example 1.

[0051] The spinning device of the present application can not only cool the filament bundle, but also eliminate the internal stress caused by the curling deformation of the filament bundle 12. Moreover, by fixedly connecting the rear end cover 2 to the cold hub shaft frame 3 and arranging it opposite to the cold hub 1, when the cold hub 1 rotates, the rear end cover 2 does not need to rotate with the cold hub 1, which can reduce the weight of the rotating part and make the operation of the cold hub 1 more stable. The cold hub device of the present application has a simple structure, good cooling effect and stable operation, and solves the technical problem in the prior art that the cold hub is prone to jumping during use.
