Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cable insulation core eccentricity control device. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer, and are wires that transmit electricity or information from one place to another. Extrusion is a plastic molding process and one of the important methods of thermoplastic molding. It is to heat the plastic raw material to make it in a viscous flow state, and under the action of pressure, it passes through the extrusion mold to become a continuum with a cross-section similar to the shape of the die, and then cools and shapes it into a glass state. It is an indispensable process in cable production. The eccentricity of cable insulation has a great impact on the service life of the cable. In the process of cable production, it is necessary to prevent the cable insulation from eccentricity.

[0003] In the prior art, Patent No. CN219789210U discloses a cable sheath processing anti-eccentricity mechanism, including an extruder, a feed hopper is inserted and fixedly connected to the upper left portion of the extruder, an extrusion head is inserted and fixedly connected to the middle portion of the right end of the extruder, an anti-eccentricity mechanism is threadedly connected to the right portion of the outer surface of the extrusion head, a support seat is fixedly connected to the lower left portion and the lower right portion of the extruder, a support frame is fixedly connected between the lower ends of the two support seats, a cooling mechanism is fixedly connected to the right end of the support frame, and a controller is fixedly connected to the lower front end of the cooling mechanism. The cable sheath processing anti-eccentricity mechanism described in the utility model ensures that the extrusion thickness of the cable sheath is uniform and consistent to prevent eccentricity by setting an anti-eccentricity mechanism, and the cable sheath can be cooled and cooled by setting a cooling mechanism and a water spraying mechanism to accelerate the cooling speed, which is suitable for wide use.

[0004] When the technical solution is used, the anti-deviation mechanism is set to prevent the cable insulation core from being eccentric. However, during use, when the positioning block becomes loose inside the extruder head, it is difficult to re-tighten and adjust the eccentric positioning block. Therefore, we propose a cable insulation core eccentricity control device. Utility Model Content
