Cable storage rack

Abstract

The invention discloses a cable storage rack. The cable storage rack comprises a first single-groove turning wheel, a second single-groove turning wheel, a first multi-groove turning wheel and a second multi-groove turning wheel, wherein the second single-groove turning wheel is arranged above the first single-groove turning wheel, the height of the first single-groove turning wheel is almost the same as the height of a water channel, the water channel is located on one side of the first single-groove turning wheel, and the first multi-groove turning wheel and the second multi-groove turning wheel are arranged in parallel and distributed above the water channel; through the water channel, soaking cooling is conducted on a cable where an insulating layer is just arranged in an extruded mode, volatile matter of insulating gas is removed, then the cable enters the second single-groove turning wheel after the cable passes through the first single-groove turning wheel and the direction of the cable is changed through the first single-groove turning wheel, then the cable enters the first multi-groove turning wheel after the direction of the cable is changed through the second single-groove turning wheel, and finally the cable is conveyed to a protective jacket squeezing-out machine head after being wound by multiple circles in the space between the first multi-groove turning wheel and the second multi-groove turning wheel. The cable storage rack is simple in structure, practical, good in dewatering effect, small in occupied space, capable of saving energy, and environmentally friendly.

Description

technical field [0001] The invention relates to an improvement of components of a production line for cable production, in particular to a wire storage rack for production of cable insulation layers, which has a simple structure, is practical, has a good dewatering effect, and occupies a small space. Background technique [0002] In the production process of the cable, there are two common processing techniques for the insulating layer and the sheath of the cable. The time is slightly ahead, and the extrusion of the sheath material is followed by the insulation material, so that the insulation layer and the sheath of the cable are basically formed at the same time. The insulation head is an adjustable eccentric head, and the nylon sheath head is an adjustment-free head. Eccentric machine head; the advantage of this process is that it is easy to adjust the eccentricity, the concentricity is very good, and the surface is smooth; however, the machine head of this processing tec...

[0002]In the production process of cables, there are two common processing techniques for the insulation layer and sheath of cables. The respective machine heads are extruded one by one, the extrusion time of the insulating material is slightly ahead, and the extrusion of the sheath material is followed by the insulating material, so that the insulation layer and the sheath of the cable are basically formed at the same time, and the insulating machine head It is an adjustable eccentric head, and the nylon sheathed head is a non-adjustable eccentric head; the advantage of this process is that it is easy to adjust the eccentricity, the concentricity is very good, and the surface is smooth; but the processing precision of this processing technology is high, and the finished product The efficiency is low and the production cost is high; 2. The insulating layer extruder head and the sheath extruder head should be used, and a certain distance should be kept between the insulating layer extruder head and the sheath extruder head. The extrusion head (not shown) is arranged in front, and the sheath extrusion head (not shown) is arranged in the rear. During the high-speed production of the cable 4, after the insulation layer is extruded, there is gas on the surface of the insulation layer, usually It needs to be cooled by immersion in the water tank 1 to remove the volatiles of the insulating gas, but the water on the surface of the insulating layer must be dried after cooling. After cooling, the blower 2 is set, and the cable 4 dried by the blower 2 is transported to the sheath extrusion head (not shown) through the delivery wheel 3, as shown in the attached As shown in Figure 1; and the ordinary production line will install an oven device behind the sheath extrusion head; this process flow The advantage is that the insulation and sheath are easy to adjust the eccentricity, the operation is simple, and the printing is easy; but in high-speed production, the core of the cable stays in the oven for a short time, and the moisture on the surface of the core cannot be completely removed, which will lead to poor subsequent printing. Clear, blistered, disjointed or slubbed sheath
