Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable processing equipment, in particular to cable pipeline processing equipment. Background Art

[0002] Cable processing is a complex process involving multiple steps and techniques. The process includes conductor processing, filament annealing, stranding, coating, insulation extrusion, cabling, shielding, outer sheathing, and testing and inspection. The above steps represent the basic process for cable processing and may be adjusted in practice based on specific product specifications and requirements. Cable processing is a highly specialized field that requires strict quality control and advanced process technology to ensure the safety and reliability of the final product. Filament annealing is a key step in cable production. Copper and aluminum filaments are heated to a specific temperature and annealed. During this process, the filaments are cooled in a cooling chamber to reduce surface oxidation caused by excessive temperatures.

[0003] Existing technologies mostly use spraying coolant or immersing coolant to cool the monofilament. However, it should be noted that a guide channel is set between the annealing furnace and the cooling box. Before the monofilament enters the coolant pool of the cooling box, the copper and aluminum monofilaments need to be pulled and moved by guide rollers. Since the monofilaments are not immersed in the cooling pool, the surface temperature of the monofilaments is high. The friction between the monofilaments and the guide rollers causes the surface temperature of the monofilaments to rise again, which can easily cause oxidation of the monofilament surface.

[0004] Therefore, how to design a cable pipeline processing equipment that can solve the above technical problems is a technical problem that needs to be solved. Utility Model Content

[0005] In order to solve the above problems, the purpose of the present utility model is to provide a cable pipeline processing equipment, which solves the problem that the friction between the existing monofilament and the guide roller before cooling is large, resulting in the surface temperature of the monofilament rising again after friction, causing the surface of the monofilament to oxidize.

[0031] Furthermore, the coolant storage tank 2 is provided with a plurality of guide rollers 21, which are staggered in an upward and downward manner. This increases the soaking time of the monofilaments passing through the cooling pool. The optimal coolant storage height should not exceed the top guide roller 21, so that the copper and aluminum monofilaments passing through are completely immersed in the coolant.

[0032] Furthermore, a sealing strip is provided at the position of the sealing hatch 3211 corresponding to the feed port of the feed bin 321 to increase the sealing performance of the feed bin 321 .

[0033] In order to keep the feed bin 321 , the coolant storage tank 2 and the winding box 4 in a vacuum state as much as possible and avoid oxidation of the copper and aluminum monofilaments, a vacuum pump 7 is provided in the feed bin 321 , the coolant storage tank 2 and the winding box 4 in this embodiment.

[0040] The copper and aluminum monofilaments pass through the guide roller 21 and the outlet guide roller 61 in turn and enter the second guide tube 6. The copper and aluminum monofilaments pass through the wiping assembly 62, and the coolant on the surface of the copper and aluminum monofilaments is wiped off by the absorbent felt 621, and finally enter the winding box 4 and are wound up by the winding roller 41.
