Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cables, and more particularly to a cooling device and a winding equipment for an insulated wire core. Background Art
[0002] In the field of cable manufacturing, insulation winding and forming is a common coating process. For example, the insulation layer of a low-loss stable-phase radio frequency coaxial cable is formed by winding polytetrafluoroethylene tape. The low-density characteristic of the polytetrafluoroethylene tape enables the cable to have lower losses and higher transmission rates. However, it also results in lower rigidity. Therefore, a metal outer sheath needs to be wound outside the insulation layer. Usually, due to the low rigidity of the insulation layer, it cannot effectively support the metal outer sheath, thus affecting the structure and electrical performance of the cable.
[0003] Due to the influence of the enhanced thermal motion of molecular chains and the transformation of crystal structure on polytetrafluoroethylene, its elastic modulus decreases with the increase of temperature. When the temperature decreases, the rigidity of the molecular chains increases and the elastic modulus rises significantly, thereby improving the rigidity of the insulation layer. In the prior art, usually, the way of controlling the ambient temperature, such as controlling the temperature of the production workshop, is adopted to achieve the cooling effect of the insulation layer. This way has a large environmental space and does not directly cool the insulation layer, resulting in higher cooling costs and poorer effects. Summary of the Invention

[0025] Please also refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 which is Figure 1 a schematic cross-sectional view of the sleeve assembly 11 in the F-F direction in FIG., Figure 3 which is Figure 2 a schematic cross-sectional view of the outer shell 111 in FIG., Figure 4 which is Figure 2 a schematic cross-sectional view of the inner core 112 in FIG. The sleeve assembly 11 includes an outer shell 111 and an inner core 112. The outer shell 111 is formed with a receiving space 101 and an opening 102. The opening 102 communicates with the receiving space 101. The inner core 112 is inserted into the receiving space 101 through the opening 102.
[0026] Optionally, a first threaded portion 111a is provided on one side of the outer shell 111 close to the opening 102, and a second threaded portion 112a is provided on the inner core 112. The first threaded portion 111a is threadedly connected to the second threaded portion 112a.
[0027] Wherein, the inner core 112 includes an inner core body 1121 and a force-receiving portion 1122. The force-receiving portion 1122 is connected to the inner core body 1121. The force-receiving portion 1122 is formed with a second threaded portion 112a and is used to receive an external force, so that the inner core body 1121 is screwed into the receiving space 101. In practical applications, the force-receiving portion 1122 can be in the shape of a nut, and an operator can twist the force-receiving portion 1122 with a wrench, so that the inner core body 1121 is screwed into the receiving space 101.
[0028] Furthermore, the inner core 112 is formed with a wire passing hole 103 and an air guiding channel 104. In this embodiment, that is, the inner core body 1121 is formed with a wire passing hole 103 and an air guiding channel 104. The wire passing hole 103 is used to pass through the insulated wire core, and the air guiding channel 104 communicates with the wire passing hole 103 and the receiving space 101 respectively.
[0029] Optionally, one side of the end of the inner core 112 close to the wire threading hole 103 is chamfered. For example, in this embodiment, the chamfer is a rounded chamfer. By this setting method, the convenience of inserting the insulating wire core into the wire threading hole 103 can be improved.
[0030] Further referring to Figure 1 and Figure 2 , the cooling mechanism 12 is connected to the outer shell 111. The cooling mechanism 12 is used to inject a cooling medium into the accommodating space 101, so that the cooling medium cools the insulating wire core through the air guiding channel 104, thereby improving the rigidity of the insulating layer of the insulating wire core. Compared with the prior art, on the one hand, the cooling cost is reduced and the cooling effect is improved.

[0031] For example, in this embodiment, the cooling mechanism 12 is selected as an eddy current cooler. The eddy current cooler is connected to the outer shell 111 through a connecting pipe port 105 on the outer shell 111, and then injects cold air into the accommodating space 101. The cold air then cools the insulating wire core through the air guiding channel 104.
[0032] Optionally, the number of the air guiding channels 104 is multiple. The multiple air guiding channels 104 are arranged in an array in the extending direction of the wire threading hole 103.

[0033] Optionally, the air guiding channel 104 is arranged in an arc shape in the circumferential direction of the wire threading hole 103 to increase the air guiding area of the air guiding channel 104 and improve the cooling effect.
[0034] Furthermore, the cooling device 10 further includes a temperature detector (not shown in the figure). The temperature detector is used to detect the real-time temperature of the insulating wire core.
[0035] Wherein, in this embodiment, the outer shell 111 is provided with a mounting hole 106, and the temperature detector is arranged in the mounting hole 106. Of course, in other embodiments, the temperature detector can also be installed in other ways, which is not limited herein.

The cooling device 10 is arranged between the wire outlet of the insulating wrapping machine and the wire inlet of the metal wrapping machine. When the insulating wrapping machine completes the wrapping operation to wind the insulating core wire to form an insulating layer, the insulating layer is cooled in the cooling device 10. After the cooling operation is completed, the metal wrapping machine then performs a wrapping operation on the insulating core wire to form a metal outer sheath on the insulating core wire.
