Background

In recent years, with the rapid development of the cable industry, the market competition pressure is more and more obvious, so that enterprises are forced to optimize the product structure, increase or improve production equipment and improve the production efficiency.

At present, equipment for producing rubber sleeve cables in domestic and foreign markets is generally single-extrusion, double-layer co-extrusion and three-layer co-extrusion continuous-vulcanization equipment, only one wire core can be extruded when the machine is started every time, and particularly, the double-machine equipment can only be used for producing double-layer or single-layer sheath extrusion.

As is well known, the rubber sleeve sulfur-connecting equipment is troublesome to start, the production efficiency is low, particularly, the production of insulated wire cores is a bottleneck in the production of multi-core cables, and the phenomenon of insufficient sulfur of the wire cores is easily caused due to overhigh production line speed. In order to meet the yield requirement, an enterprise can only be forced to increase equipment and personnel to meet the actual production, and how to improve the production efficiency on the premise of limited production equipment is a problem to be considered.

Further, the aperture of the die core hole of the die core is set to be the same or different in size.

The double-in and double-out production process of the rubber sleeve cable is characterized in that conductor wire cores are respectively arranged on two automatic pay-off devices, wire storage is carried out before a wire storage device on the automatic pay-off devices, the two conductor wire cores are wound on a tension pulley in front of a die head in parallel after passing through the wire storage device, the two conductor wire cores pass through the tension pulley and pass through a die core side by side, glue runs out of the die, air pressure and traction speed are set, and a machine is started normally;

after the wire cores are hermetically cooled down and pass through the drying device, the wire cores are led into the wire collecting and storing device through the lower traction device, and finally the two insulated wire cores are collected on the two wire collecting discs.

Compared with the prior art, the invention has the advantages that:

1. in the aspect of the double-in double-out production process production equipment, new equipment does not need to be purchased, and only the auxiliary device of the original double-machine continuous sulfur equipment needs to be modified, namely, the front and rear wire storage devices for up-and-down traction are added, so that the cost is more economic.

2. In the aspect of the tooling die for the cable extrusion process, the processing of the die is similar to the processing of a conventional flat cable die, and no additional cost is added.
