Description

Technical Field

[0001] The present application relates to the field of cable water blocking technology, and in particular to a cable water blocking glue coating device. Background Art

[0002] Cables are the main equipment for power and signal transmission and are used in a wide range of situations. Among them, watertight cables used in seawater are highly watertight, bend-resistant multi-core integrated cables suitable for ships, offshore oil platforms, deep-sea resource exploration and other fields. In order to ensure its watertightness, it is often necessary to coat the cable core with water-blocking glue, hot-melt glue, etc. during the cable manufacturing process. In this way, even if the cable casing is broken, the water-blocking glue can prevent further intrusion of seawater.

[0003] After searching, an invention with publication number CN112420288A discloses a watertight cable coating device, including a coating box and a controller. The interior of the coating box has a funnel-shaped groove, and the water-blocking glue is placed in the groove. A temperature detection sensor and an electric stirring device are installed inside the groove. The lower end of the groove has multiple metal springs, and the bottom of the groove is a cylindrical through hole. The inner side of the cylindrical through hole has an internal thread, and a fixed wire pipe is installed on the internal thread. A heating device is installed in the coating box, and the heating device heats the water-blocking glue in the groove. The controller is installed on the coating box and is connected to the temperature detection sensor, the heating device and the electric stirring device.

[0004] This patent can adjust the thickness of the glue according to the thickness of the cable, making cable glue coating convenient and quick. It uses a detachable fixed wire tube to adjust the coverage thickness of the water-blocking glue when discharging the cable after coating. However, when the entire equipment is shut down, the water-blocking glue remaining at the fixed wire tube is easy to solidify and block the pipe mouth. The solidified water-blocking glue needs to be manually cleaned by the staff to ensure that the pipe mouth is unobstructed so that the cable can pass smoothly when it is turned on next time. If the solidified water-blocking glue is not cleaned properly, on the one hand, it will affect the passage of the cable, and on the other hand, it will cause the control of the coating thickness to fail, affecting work efficiency and coating quality. Therefore, a cable water-blocking glue coating equipment is needed that can quickly heat, melt and clean the solid water-blocking glue at the discharge pipe mouth when the machine is turned on.
