Description

Technical Field

[0001] This utility model belongs to the field of cable production technology, and more specifically, it relates to a cable surface moisture blowing device. Background Technology

[0002] Drying devices are standard components of plastic extrusion production lines widely used in the cable manufacturing industry. Their function is to blow away residual moisture from the surface of the extruded and water-cooled cable, ensuring its dryness and guaranteeing the quality of subsequent surface marking. After the cable sheath is extruded and cooled, residual moisture on the cable surface generally needs to be thoroughly removed to ensure effective adhesion of the printed markings and guarantee marking quality. Currently, the blowing of moisture from the cable surface commonly uses fixed annular circumferential drying heads or nozzles of various shapes. These blowing devices are all fixed and must be kept at an appropriate distance from the cable surface.

[0003] The shortcomings of existing technologies are as follows: when using spatially fixed annular circumferential blowing heads or various types of nozzles for blowing, the blowing device needs to be as close to the cable as possible to ensure the blowing effect; at the same time, to avoid friction with the cable and damage to the cable surface, an appropriate distance must be maintained. In practice, due to the large weight of cables, especially large-diameter cables, during the extrusion process, the cable often cannot be guaranteed to be perfectly straight during its movement. Therefore, the use of blowing devices has obvious defects or contradictions, and cannot effectively achieve zero impact on both the blowing effect and the cable surface quality.

[0004] The prior art includes a technology entitled "A Surface Dehydration Device" with publication (announcement) number "CN220553328U". This technology discloses a surface dehydration device, including a treatment box and a cleaning box. The treatment box has a top box welded to its inner wall. The treatment box is equipped with a cleaning mechanism, which includes a splined outer cylinder, a splined shaft, a brush, a motor, and a moving connecting plate. The cable is inserted into the splined shaft, and then the motor is turned on to drive gear two, which in turn drives gear one to rotate the splined outer cylinder. At the same time, the moving connecting plate drives the splined shaft, which allows the brush to remove impurities that are difficult to remove from the outer surface of the cable. An exhaust pipe, a fan, and an electric heating element are provided. When in use, the fan and the electric heating element can be turned on to quickly dry the moisture on the outer surface of the cable. This utility model can clean up impurities and is equipped with a vertical water pump, drain pipe, water tank, nozzle, and collection box. When in use, the vertical water pump can be turned on to discharge the water in the water tank through the nozzle at the bottom of the drain pipe, so as to wash the impurities on the outer wall of the cable and improve the cleanliness of the cable.
