Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: because the silica gel is heated and melted in the extruder to coat the outside of the cable core, and the silica gel on the surface of the cable that has just been extruded is not sufficiently melted and mixed with its constituent particles, it is easy to appear. Some granular sticky substances
However, the guide wheel is in the forming groove, and affected by the temperature of the forming groove, the surface temperature of the guide wheel is relatively high, and the granular adhesive substance on the silica gel coating layer of the cable is easy to stick to the guide wheel, and the The continuous pulling of the cable will cause the cable coating to be damaged or peeled off continuously, resulting in the hidden danger of continuous scrapping of the extruded cable

Embodiment

[0036] refer to figure 1 and figure 2 , a cable-coated silica gel heat-setting production device disclosed in the present invention includes an extruder 1, a forming tank 11 and a cooling tank 12 arranged in sequence. In order to reduce or prevent the adhesion between the covering layer of the cable 13 and the forming groove 11 , the forming groove 11 in this embodiment includes several split grooves 111 , and a heating element 112 is disposed in the split grooves 111 . The cable core is wrapped with a cladding layer in the extruder 1, and silicon rubber is used as the cladding layer in this embodiment. When the cable 13 just extruded from the extruder 1 passes through each split tank 111 in turn, it is heated and shaped by the heating element 112 in the split tank 111 , and finally enters the cooling tank 12 to be cooled by water.

[0037] In particular, the principle of heating and setting the divided groove 111 by the heating element 112 is: the silica gel coating layer ...

Abstract

The invention discloses a cable coating silica gel heat setting production device, which relates to the technical field of cable coating production, and comprises an extruder, a forming groove and a cooling groove sequentially arranged, wherein the forming groove comprises a plurality of split grooves, heating elements are arranged in the split grooves, and guide assemblies are arranged between adjacent split grooves; the heating elements are annularly arranged, and the parts, in the length direction of the split grooves, of the heating elements are located on the two sides of the cable in thelength direction; the guide assembly comprises symmetrically-arranged connecting plates, and a guide roller is rotationally connected between the connecting plates. The device has the effect of reducing or preventing damage or continuous scaling of a coating layer of a cable, thereby preventing continuous discard of an extruded cable.

Description

technical field [0001] The invention relates to the technical field of cable coating production, in particular to a cable coating silicone heat-setting production device. Background technique [0002] Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. The cable is mainly insulated by pvc plastic particle processing sheath and copper wires of various specifications are twisted into cables. Copper wires are mostly covered with silica gel and qualitatively determined by electric heating. [0003] Existing cable sheathing extruders are used in wire and cable factories to heat-extrude polyethylene, polyvinyl chloride, and silica gel to insulate wire cores or use them as cable sheaths. The whole machine consists of a pay-off stand, a pressing mechanism for pressing th...
