Abstract
Description
Technical Field
[0001] The utility model belongs to the field of cable production, and in particular relates to a device for producing flat wires. Background Art
[0002] At present, the existing flat wires are all formed by arranging a plurality of coaxial cables 1 in parallel, and the cable 1 includes a conductor 101, an insulating layer 102, a conductor 2 103 and an insulating layer 2 104 from the inside to the outside. Fig.10 As shown, during processing, the cables 1 need to be placed in parallel first, and then a layer of sheath is pressed out. The traditional method of pressing the sheath in parallel has the following disadvantages: 1) The extrusion mold is special and has high requirements on size; 2) When pressing out, the core wires will be misaligned due to unstable tension, resulting in a high defect rate; 3) The laser is easy to break the inner skin during processing, resulting in defects. Moreover, due to the existence of the sheath, the outer diameter of the cable is relatively large, and the space occupied is large.
[0003] Therefore, an apparatus for flat wire production is designed to solve the above problems.
[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model.

In this solution, a plurality of coaxial cables are sent out through the wire feeding device, the cables are merged after passing through the wire paralleling device, the glue is applied by the glue injection device, the glue is bonded in place by the heating device, the glue is condensed firmly by the cooling device, and the flat wire is wound by the wire take-up device; it is not necessary to put a sheath on the outside of the multi-core coaxial cable, saving space and cost.
[0007] Furthermore, the wire feeding device is composed of a plurality of wire feeding frames arranged side by side, each of which is provided with a rotatable winding column. In this solution, the cable is fed out through the wire feeding frame and the wire is fed through the rotatable winding column, which improves the efficiency of cable feeding and the processing efficiency of the flat wire.
[0008] Furthermore, the parallel cable device includes a cable placement base, and the cable placement base is provided with a plurality of cable placement grooves arranged side by side.

[0012] Furthermore, an eye mold device is provided between the heating device and the cooling device, and the shape of the mold hole of the eye mold device is set corresponding to the cross-sectional shape of the flat wire. In this solution, the flat wire wrapped with glue comes out through the mold hole of the eye mold device, and the excess glue on the upper layer, the lower layer and the two sides can be scraped off through the mold hole, thereby preventing the outer diameter of the flat wire from increasing due to the glue layer.
[0013] Furthermore, the glue injection device includes a plurality of groups of upper glue injection heads and lower glue injection heads, and the upper glue injection heads and the lower glue injection heads are arranged one by one in a vertical correspondence. In this solution, after the parallel coaxial cables enter the glue injection device, the upper glue injection head and the lower glue injection head simultaneously spray glue-like substances to achieve glue injection between the cables, which can prevent other positions of the cables from being contaminated by the glue.
[0014] Furthermore, the cooling device comprises a cooling cavity with openings at both ends, and a water cooling pipe is arranged in the cavity wall of the cooling cavity.
