Description

Technical Field

[0001] The invention relates to the technical field of cable production, in particular to a rolling device for producing cross-linked polyethylene insulated double-sheathed power cables. Background Art

[0002] Cable production is a complex and sophisticated industrial process. In cable production, high-quality conductor materials such as copper or aluminum must be selected first to ensure good conductivity. Then, the conductor is drawn into the required diameter through a wire drawing process. The selection of insulating materials is also crucial, which can ensure the safe operation of the cable and prevent leakage. The insulating material is evenly coated on the conductor to form an insulating layer, which requires precise process control. Depending on the purpose and requirements of the cable, it may also be necessary to add a shielding layer, sheath, etc. to enhance the cable's anti-interference ability and mechanical strength; During the cable production process, the cables need to be rolled so that the outer sheath and inner core of the cables can be tightly connected together; however, when rolling the cables on the market, they are not suitable for rolling cables of different diameters. Summary of the invention

[0003] To achieve the above purpose, the present invention is implemented through the following technical solutions: a rolling device for producing cross-linked polyethylene insulated double-sheathed power cable, comprising a bottom plate, a support frame is fixedly connected to the corners of the upper surface of the bottom plate, a threading device is fixedly connected to the top of the support frame, and the threading device can be arranged to thread the cross-linked polyethylene insulated double-sheathed power cable, so that when the cross-linked polyethylene insulated double-sheathed power cable contacts with an extrusion mechanism, the cross-linked polyethylene insulated double-sheathed power cable will not curl or move smoothly, the threading device comprises a wire frame, the wire frame is fixedly connected to the upper surface of the support frame, and the end of the wire frame is fixedly connected to a track tube; The inner cavity of the track tube is slidably connected with an extrusion mechanism, and the extrusion mechanism includes a sliding plate. By setting the sliding plate, it can slide in the inner cavity of the track tube, so that the extrusion plate produces an effect of vertical up and down movement directly above the wire frame. The sliding plate is slidably connected to the inner cavity of the track tube, and the upper surface of the sliding plate is fixedly connected with the extrusion plate. By setting the extrusion mechanism, the cross-linked polyethylene insulated double-sheathed power cable placed in the inner cavity of the threading device can be extruded, and the rolling effect of cables of different diameters can be achieved through adaptive adjustment and manual adjustment.

[0004] Preferably, the number of the wire frames is two, and the two wire frames are symmetrically arranged. The upper surface of the wire frame is fixedly connected with a first extrusion strip. The arrangement of the two wire frames can respectively realize the guiding work of the inlet and outlet ends of the cross-linked polyethylene insulated double-sheathed power cable. The arrangement of the first extrusion strip can make the lower surface of the cable squeezed with the first extrusion strip when the upper surface of the cable is squeezed, so that the lower skin of the cable will also be squeezed tightly.

[0005] Preferably, the outer side surface of the track tube is fixedly connected to a first connecting rod, and the end of the first connecting rod away from the track tube is fixedly connected to a limiting tube.

[0009] Preferably, a third extrusion strip is fixedly connected to the top surface of the inner cavity of the extrusion plate, and an adjustment mechanism is fixedly connected to the upper surface of the extrusion plate. The adjustment mechanism includes a track frame, and the track frame is fixedly connected to the upper surface of the extrusion plate. By setting the adjustment mechanism, the upper skin of the cross-linked polyethylene insulated double-sheathed power cable can be extruded and can cooperate with the first roller, so that the cross-linked polyethylene insulated double-sheathed power cable can move more stably.

[0010] Preferably, a sliding rod is slidably connected to the inner cavity of the track frame, and a spring is fixedly connected to the upper surface of the sliding rod. The setting of the sliding rod can stably slide in the inner cavity of the track frame and produce an effect of vertical up and down movement. The top of the spring is fixedly connected to the top surface of the inner cavity of the track frame. The setting of the spring can squeeze the sliding rod to make the sliding rod move downward. The end of the sliding rod is fixedly connected to a fourth connecting rod, and the bottom end of the fourth connecting rod is fixedly connected to a ring. A second rotating rod is rotatably connected to the inner cavity of the ring, and a second roller is fixedly connected to the end of the second rotating rod. The setting of the ring can limit the second rotating rod, so that the second rotating rod drives the second roller to produce stable rotation.

[0011] The present invention provides a rolling device for producing cross-linked polyethylene insulated double-sheathed power cables. It has the following beneficial effects: 1. The rolling device for producing cross-linked polyethylene insulated double-sheathed power cable can thread the cross-linked polyethylene insulated double-sheathed power cable by arranging a threading device, so that when the cross-linked polyethylene insulated double-sheathed power cable contacts with the extrusion mechanism, the cross-linked polyethylene insulated double-sheathed power cable will not curl or move smoothly.
