Production device and method of waterproof wire

Abstract

The invention discloses a production device of a waterproof wire. The production device comprises a pay-off rack, an extruder and a wire outlet device, the pay-off rack, the extruder and the wire outlet device are connected in sequence, and a gluing device is further arranged between the pay-off rack and the extruder. A wire core conveyed by the pay-off rack sequentially passes through the gluing device, the extruder and the wire outlet device, the gluing device is filled with a hot melt adhesive in a molten state, and the wire core penetrates through the hot melt adhesive. According to the waterproof production device of the wire, the waterproof problem between the outer sleeve and the wire core or a semi-finished product is solved, the waterproof problem of the whole industry is technically broken through, automatic production operation can be achieved, and the productivity can be effectively improved. The hot melt adhesive liquid is more stably attached to the wire core or the semi-finished product under precise temperature control, and then the hot melt adhesive liquid is more tightly attached to the insulating jacket, so that the complete waterproof effect is achieved.

Description

Technical field: [0001] The invention relates to the technical field of cable processing and production, in particular to a production device and method for a waterproof thread. Background technique: [0002] The existing cable processing device is used for power lines, power cables, coaxial cables, communication cables, transmission cables, BV civilian lines, electronic lines, computer lines, construction lines, data communication cables, radio frequency lines, HDMI data lines, When processing and producing various types of high-temperature silicone cables, Teflon cables, coaxial cables, etc., the general process is: first, the metal wires come out of the pay-off frame and pass through the head of the main machine, and at the same time, the suction machine sucks in the rubber for heating-then the main machine heats the metal The wire is covered with glue-and then pulled by the drawing machine-finally to the wire take-up machine to take up the wire and coil it.

Problems solved by technology

[0003] However, some cables are often multi-core metal wires. When these multi-core metal wires are combined, their cross-sectional profile is not a circle, but a "quincunx shape" with multiple circles tangent. If these metal wires are directly If the outer side is covered with an insulating layer, the insulating layer is not completely attached to the metal wire, but there is a gap

Therefore, in the actual use process, the water in the external environment is easy to enter between the insulating layer and the metal wire from both ends of the wire end, resulting in potential safety hazards in use.
