Description

Technical Field

[0001] The invention relates to the field of cable production, and in particular to an extruder and a production process for cable production. Background Art

[0002] Wires and cables all start with conductor processing, and insulation, shielding, cabling, sheaths, etc. are added layer by layer on the outside of the conductor to make wire and cable products. The more complex the product structure, the more superimposed layers there are. Currently, during cable processing, a large portion of the outer side of the cable needs to be covered with an insulating layer, and part of the insulating layer is achieved through extrusion.

[0003] China Patent Network CN214123591U discloses an extruder for wire and cable production, which relates to the technical field of wire and cable production. The present invention aims to solve the problem of the phenomenon that the plastic on the outside of the cable sticks together when the cable is directly collected after packaging. The present invention comprises: an extrusion concave bracket, on which a hot melt structure, a plastic collection structure and a cooling structure are installed; the beneficial technical effect is: the hot melt structure is used to uniformly package the outside of the cable with hot melt adhesive, and at the same time, the cooling structure and the auxiliary limiting assembly extrude and cool the packaged cable, thereby avoiding the phenomenon of adhesion when directly collected after packaging, and at the same time, the packaged and cooled cable is uniformly moved and rolled in the horizontal direction by the plastic collection structure, thereby avoiding the phenomenon of twisted wire.

At the same time, only the two sides of the cable can be directly cooled by the limiting wheel, and all parts around the cable cannot be cooled, which affects the shaping effect of the hot melt adhesive.
