Abstract

The invention relates to a low-shrinkage shaping high-coaxiality cable cladding production line, and relates to the technical field of cable production. The production line comprises a feeding device, an extrusion molding device, a cooling device, a drying device, a driving device and a receiving device which are arranged in sequence, wherein a pre-shaping device is arranged between the extrusion molding device and the cooling device, the pre-shaping device comprises an L-shaped heating support, a guide plate and a redirecting shaft, the L-shaped heating support comprises a vertical section and a horizontal section which are connected, the vertical section is located below a discharging end of the extrusion molding device, and the horizontal section is located at a feeding end of the cooling device; one end of the guide plate is mounted on the inner side of the vertical section, and the other end of the guide plate extends towards the discharge end of the extrusion molding device; and the redirecting shaft is mounted on the L-shaped heating support and located at the right angle of the L-shaped heating support, and a gap is formed between the peripheral wall of the redirecting shaft and the L-shaped heating support. The production line has the advantages that uniform cladding of a cladding material in the circumferential direction of a cable is facilitated, and the shrinkage deformation is small, so that the coaxiality of the cable and a sheath is improved.

Description

technical field [0001] The application relates to the field of cable production, in particular to a low shrinkage shaping and high coaxiality cable coating production line. Background technique [0002] The current structure of the cable is as figure 1 As shown, stranded annealed soft copper is used as the conductor, and the surrounding wall of the conductor is covered with polyethylene as the insulating layer. The wire pair chromatography is paired according to the YD / T1019-2001 standard, the white wire is twisted with the blue wire, the white wire is twisted with the orange wire, the white wire is twisted with the green wire, and the white wire is twisted with the brown wire. Then wrap the polyester tape around the four pairs of cables so that the four pairs of cables are wrapped together to form a cable, then wrap the polyester tape with single-sided aluminum foil to form a shielding layer, and finally use flame-retardant PVC as the sheath Wrapped around the circumferen...
