Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Referring to fig. 1-4, an embodiment of the present invention includes:

the utility model provides a simplex position extruder of multilayer insulated wire, including the sinle silk supply mechanism 1 that connects gradually, two port extrusion mechanisms 2, cooling body 3, admission machine constructs 4, two port extrusion mechanisms 2 are including pressing out mould 5, with the first feed inlet 6 of pressing out mould 5 intercommunication, with the second feed inlet 7 of pressing out mould 5 intercommunication, be provided with the sinle silk passageway 8 that supplies the sinle silk to pass through on the pressing out mould 5, first feed inlet 6 and sinle silk passageway 8 intercommunication, second feed inlet 7 and sinle silk passageway 8 intercommunication, be provided with first opening 9 and second opening 10 on the sinle silk passageway 8, first feed inlet 6 communicates with sinle silk passageway 8 through first opening 9, second feed inlet 7 communicates with sinle silk passageway 8 through second opening 10. The core supply mechanism 1, the cooling mechanism 3 and the take-up mechanism 4 are commonly used feeding, cooling and receiving devices in the market, and the internal structure thereof is not the invention point of the patent, so the details are not described herein.

The first opening 9 and the second opening 10 do not coincide at one point. The central axis of the first opening 9 is parallel to the central axis of the second opening 10.
