Embodiment 1

[0065] A kind of processing technology of multi-layer sheathed cable 9, such as figure 1 shown, including:

[0066] S10: Extrude the first insulating layer 905 through the first extrusion process;

[0067] Specifically, the operating temperature during the first extrusion molding process is 140°C to 180°C. If the temperature is too low, it will be difficult to extrude and plugging will easily occur; if the temperature is too high, it will be easy to carbonize.

[0068] S11: cooling the temperature of the first insulating layer 905 to the embossing temperature;

[0069] Further, in this embodiment, the embossing temperature is greater than or equal to 90°C and less than or equal to 120°C. In other embodiments, the embossing temperature is greater than or equal to 100°C and less than or equal to 110°C. Specifically, the embossing temperature should not be too high. If the embossing temperature is too high, the first depressed portion that is extruded is prone to defects such ...

Embodiment 2

[0082] Such as figure 2 As shown, a processing system for a multi-layer sheathed cable 9 is used to perform the processing technology provided by the first embodiment above, and includes an outlet machine 1, a first extruder 2, a first cooling device 3, Embossing device 4 , second extruder 6 , second cooling device 7 and wire take-up device 8 .

[0083] Specifically, the first extruder 2 is used to form the first insulating layer 905, and the embossing device 4 is used to emboss the first depression on the outer surface of the first insulating layer 905; the second extruder 6 is used to form The second insulating layer 906 . The insulating material in the first extruder 2 is different from the insulating material in the second extruder 6 . The properties of different materials complement each other, making the overall performance of the sheath more excellent.

[0084] In this embodiment, the first cooling device 3 includes a first water tank, a first circulating pump and a...

Embodiment 3

[0090] Such as image 3 As shown, a multi-layer sheathed cable 9 is produced by the processing technology described in the first embodiment and the processing system in the second embodiment, and includes an insulating core wire 901, a wrapping tape 902, and a shielding layer from the inside to the outside. 903, metal braided mesh 904 and sheath.

[0091] The sheath includes a first insulating layer 905 and a second insulating layer 906 covering the first insulating layer 905; a side of the first insulating layer 905 close to the second insulating layer 906 is provided with a first depression part, the side of the second insulating layer 906 close to the first insulating layer 905 is provided with a first protruding part 9061 , and the first protruding part 9061 is embedded in the first recessed part. Specifically, when the first protruding part 9061 is embedded in the first concave part, the relative movement between the first insulating layer 905 and the second insulating l...

Abstract

The present invention relates to the cable production technology field, in particular to a processing technology of a multilayer sheath cable and a processing system of the multilayer sheath cable. The processing technology of the multilayer sheath cable comprises the steps of extruding a first insulating layer via a first plastic extrusion process; carrying out the coining process on the outer surface of the first insulating layer to form a first recess part on the outer surface of the first insulating layer; extruding a second insulating layer on the outer surface of the coined first insulating layer via a second plastic extrusion process. The processing technology of the multilayer sheath cable and the processing system of the multilayer sheath cable provided by the present invention can use a general plastic extrusion device to produce the multilayer sheath cable, and are simple in technology and low in equipment cost.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a processing technology and a processing system for a multi-layer sheathed cable. Background technique [0002] The outermost insulating layer of the cable is called the sheath. The general sheath is made of one material, the process is simple, and the production cost is low. Some sheaths are made of two layers of materials, and the properties of the two materials in the double-layer sheath can complement each other, so that a sheath with more excellent performance can be obtained. [0003] At present, the double-layer co-extrusion technology used in the cable industry is mainly realized through special double-layer co-extrusion equipment, that is, one equipment extrudes two layers of insulating materials at the same time, but the equipment is expensive, and it has special effects on processing materials and process control. higher requirements. [0004] Therefore, th...
