Hot air drying device with safety protection mechanism for cable outer sheath processing

Abstract

The invention belongs to the technical field of cable sheath processing equipment, and particularly relates to a hot air drying device with a safety protection mechanism for cable outer sheath processing. The hot air drying device with the safety protection mechanism for cable outer sheath processing comprises a supporting mechanism, a heating mechanism and a conveying mechanism. The supporting mechanism comprises a mounting pipe and supporting legs, and two ends of the bottom surface of the mounting pipe are fixedly connected with the two symmetrically arranged supporting legs. The four heating mechanisms are arranged on the periphery of the outer wall of the mounting pipe at equal intervals. A cable penetrates through the inner side of the mounting pipe and is located at the center of the mounting pipe, an external air feeder conveys air flow into the heating box, the air flow is heated through an electric heating net, the temperature of the heated air flow is high, and the high-temperature air flow is conveyed to a spray head through a threaded pipe, a threaded conveying pipe and a threaded sleeve pipe and finally sprayed out of the spray head to the outer side wall of a cable sheath to heat and dry the cable sheath, so that the inner side of the cable sheath is better bonded and fixed with the outer wall of a cable, and the attachment is very tight.

Description

technical field [0001] The invention belongs to the technical field of cable sheath processing equipment, and in particular relates to a hot air drying device for processing cable outer sheaths with a safety protection mechanism. Background technique [0002] The cable is usually a rope-like cable twisted by several wires or groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating covering layer. In the air or installed underground or underwater, used for telecommunications or power transmission, the insulating material used for cables should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant, commonly used in cables The insulation materials used include oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber, etc., and the cable sheath needs to be installed on the outsid...
