Parallel type lapping apparatus used for fireproof cable insulation layer mica tape lapping

Abstract

The invention relates to a parallel type lapping apparatus used for fireproof cable insulation layer mica tape lapping, comprising a lapping rack and a rotary type lapping head. The rotary type lapping head is fixed to the lapping rack; the lapping rack transmits power to drive the rotary type lapping head to rotate; a mica tape is arranged on the rotary type lapping head and is lapped on a cable conductor through the rotation of the rotary type lapping head. Compared with prior arts, the parallel type lapping apparatus possesses the advantages of low cost and wide application.

Description

technical field [0001] The invention relates to a cable wrapping device, in particular to a parallel wrapping device for mica tape wrapping of a fireproof cable insulating layer. Background technique [0002] With the development of the country, the safety requirements for wires and cables are getting higher and higher. In important places such as high-rise buildings, large public facilities, coal mines and ships, there will be an increasing demand for flexible fireproof cables, and flexible fireproof cables The insulation layer of the cable is wrapped with multi-layer mica tape. At present, the wrapping method of mica tape by domestic equipment manufacturers is basically concentric wrapping head. Concentric wrapping head has many disadvantages, such as: each wrapping head can only Wrap a layer of tape, and the amount of packing is limited, and the limited amount of packing results in a limited length of wrapping, which limits the production of large-length fireproof cables;...

[0002] With the development of the country, the safety requirements for wires and cables are getting higher and higher. In important places such as high-rise buildings, large public facilities, coal mines and ships, there will be an increasing demand for flexible fireproof cables, and flexible fireproof cables The insulation layer of the cable is wrapped with multi-layer mica tape. At present, the wrapping method of mica tape by domestic equipment manufacturers is basically concentric wrapping head. Concentric wrapping head has many disadvantages, such as: each wrapping head can only Wrap a layer of tape, and the amount of packing is limited, and the limited amount of packing results in a limited length of wrapping, which limits the production of large-length fireproof cables; moreover, the wrapping insulation layer of fireproof cables is not just one layer, but more It can reach 5-6 layers, so it is necessary to increase multiple wrapping heads, which not only increases the length of the equipment, but also increases the purchase cost of the equipment
