Description

Technical Field

[0001] The utility model relates to the technical field of silicone oil coating, in particular to a silicone oil atomizing device for electric wire production. Background Art

[0002] During the manufacturing process of power cables, the insulating core or the cable core wire and the insulating sheath are prone to adhesion, causing the insulating core and the sheath to stick to each other. This adhesion phenomenon is especially prone to occur when the outer sheath is extruded on the cable core wire by an extruder. This adhesion phenomenon not only seriously affects the flexibility of the cable, affects the subsequent processing and laying and installation of the cable, but also makes it difficult to strip the cable, and even causes the insulation layer to tear when the cable is bent, reducing the service life of the cable. Therefore, it is necessary to apply silicone oil on the outside of the insulating core to solve the above problems.

[0003] The existing silicone oil atomization devices on the market are expensive, and the silicone oil spraying is uneven, which cannot stabilize the stripping force of the insulating sheath. In the existing production, either manually apply silicone oil with a sponge, or put the sponge in a box, and then use an oil pump to regularly pump oil into the box. The sponge absorbs the silicone oil, and the insulating wire core passes through the sponge to achieve the purpose of silicone oil spraying on the insulating wire core. This method is cumbersome to operate, has a large environmental pollution on the production site, wastes a lot of silicone oil, and cannot achieve uniform application of silicone oil. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a silicone oil atomizing device for electric wire production, which has low equipment cost, simple structure and convenient operation. The silicone oil can be evenly sprayed on the insulating wire core to reduce the stripping force of the sheath layer and avoid polluting the on-site environment.

A liquid level observation window 121 is provided on the door panel 12 of the shell 1 corresponding to the position of the liquid level display 31, which is convenient for the staff to observe the liquid level in the oil tank 3 so as to replenish the silicone oil in time. The bottom of the atomizer box 2 is connected to the oil tank 3 through an oil pipe 22, and the atomizer box 2 and the oil tank 3 are connected through the oil pipe 22. The excess silicone oil sprayed by the spray device 4 will flow into the bottom of the atomizer box 2, and then flow back to the oil tank 3 from the oil pipe 22 to avoid waste.

[0025] The spray device 4 includes a plurality of sprayers 41, an air control valve 42, an oil-water separator 43 and a diverter joint 44.
