Description

Technical Field

[0001] The utility model relates to the field of cross-linked wire core production, in particular to a tugboat device for preventing the cross-linked wire core from being scratched. Background Art

[0002] When producing insulated wire cores, an insulating layer needs to be wrapped around the outer surface of the wire core. During the processing, the insulating layer needs to be vulcanized. The wire core is sent into a vulcanizing device to cause the insulating layer to be cross-linked under certain temperature conditions. For example, a Chinese patent discloses an auxiliary sealing device at the lower end of a medium-voltage cross-linked cable production line (Announcement No. CN207213151U). Although this device can reduce the length of waste cables and save costs, during the vulcanization process, the outer surface of the wire core will inevitably contact the inner side wall of the vulcanizing device, causing the outer surface of the wire core to directly contact the sulfide, resulting in scratches on the outer surface of the wire core, affecting the production quality of the wire core.

The moving direction of the limiting roller 401 is adapted to the moving direction of the wire core. It should be noted that the limiting roller 401 connected by the damping rod 47 and the limiting spring 49 can, under the action of the torsion spring 45 and the fixed block 46, play a role in limiting and supporting the passing wire core, preventing the wire core from contacting the inner wall of the vulcanization channel 3 during the movement, thereby reducing the occurrence of scratches.

[0022] like Figure 1-3As shown, the inner wall of the vulcanization channel 3 and the corresponding sliding paths of the two sliders 42 are provided with a slide groove 31, the inner wall of the support ring 41 is provided with a fixing groove 402, and the inner wall of the fixing groove 402 is penetrated by a fixing screw 403.
