Problems solved by technology

The disadvantage of this process is that if a compact compression mold is used when wrapping the compound multiple times, the inner mold is easy to scratch the first layer of cladding, and because each layer of cladding is easily polluted due to multiple wrapping, and the positioning It is not allowed to be easily eccentric; if the extrusion die is used, it mainly depends on the characteristics of the material of the wrapping itself to achieve a good fixation between the wrapping, the metal inner core, and the PTC inner core. Short circuit and mismatch occur after using for a long time

Abstract

The invention discloses a heat tracing cable manufacturing device and a using method thereof. The heat tracing cable manufacturing device comprises a machine head, an active pay-off machine, a conductor pay-off reel, a dancing wheel, a heater, a co-extrusion head, a constant-temperature water tank, a traction device and a take-up reel. The co-extrusion head comprises a composite die set, a shell body, a front pressure cover and a rear pressure cover. The composite die set comprises a die core supporting sleeve, an incoming wire positioning die set, and an inner conductor layer die set, a PTC layer die set and an insulating layer die set. The inner conductor layer die set comprises a fixed die, a rotary die and a first brake assembly. The composite die set further comprises a second brake assembly. The heat tracing cable manufacturing device realizes the one-step coating of metal inner cores with an inner conductor layer, a PTC heating body layer and a composite insulating layer by means of the composite die set, and drives the rotation of fusion coating materials by means of the braking effects of a first linkage portion and a second linkage portion, so that the coating materials are tightly adhered.

Description

technical field [0001] The invention relates to the field of electric wire and cable manufacturing equipment, in particular to a heating cable manufacturing device and a method for using the same. Background technique [0002] For heating cables, three-layer co-extrusion devices have been widely used in the domestic cable industry, and some domestic manufacturers also refer to imported three-layer co-extrusion devices for manufacturing. For the double-core double-layer structure ribbon cable commonly used in the fields of communication, petrochemical and household appliances, imported and some domestic manufacturers mostly use the head of the three-layer co-extrusion device with annular feed channel to manufacture, generally through The production process of layered and multiple extrusion coatings firstly coats the two core structures with a layer of compound and then covers more than two layers of compound; for example, a layer of coating is coated on the conductor first, a...
