A special flame-retardant cable production process for LED lighting and its production equipment

Abstract

The invention relates to a production process and production equipment of a special flame-retardant flat cable for LED illumination. The production equipment comprises a winding displacement machine,an extruder, a calibrator, a cooling device and a winding device which are arranged in sequence. An extrusion die head is detachably arranged on a machine head of the extruder. A first guide plate anda second guide plate which are oppositely arranged are detachably arranged on the inner wall of the extrusion die head. A plurality of guide holes matched with the wires are formed in the first guideplate in a penetrating manner. An injection hole matched with the flame-retardant flat cable is formed in the second guide plate. The injection hole comprises a plurality of through holes and throughgrooves used for communicating every two adjacent through holes, the opening area of each through hole is larger than that of the corresponding guide hole, a sealing plate used for sealing the guidehole and part of the injection hole is arranged in the extrusion die head in a sliding mode, and a locking device used for locking the sealing plates is arranged on the extrusion die head. The numberof the guide holes through which the wires can penetrate is changed through sliding of the sealing plate in the extrusion die head, and convenient production of flame-retardant flat cables with different core numbers through the same extrusion die head is achieved.

Description

technical field [0001] The invention relates to the technical field of production of special wires, in particular to a production process and production equipment for a special flame-retardant cable for LED lighting. Background technique [0002] PVC cable is generally arranged in strips of power lines or signal lines, and then extruded into a strip-shaped cable with a protective sleeve with a certain performance. According to the use scene of the cable, there are usually 3Pin, 4Pin, 6Pin, 8Pin and other specifications. , different purposes of power lines, signal lines, control lines, etc. can be integrated in the protective cover, making the connection between electrical equipment more intuitive and tidy, eliminating the need for wiring harness binding process, small footprint, widely used in Electronics, lighting, precision instruments and other fields. The core of this kind of cable is mostly tinned or bare copper stranded wire of 0.03~1.31㎡, the distance between two adj...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: in actual production, the extrusion die or die of the extruder needs to be frequently replaced due to the different number of wires in the cable, and the extrusion die or die and the die are easily reduced after frequent disassembly and assembly. The tightness of the connection of the extruder head, the locking screw is also easy to slip, and it is time-consuming and laborious, which is not conducive to the improvement of production efficiency
