Description

FIELD OF THE INVENTION The present invention relates generally to cable dryers, and in particular, for example,
The present invention relates to a cable drier equipped with an air wiper suitable for removing the cooling liquid adhering to the outer peripheral surface of the cable after being molded by an extruder, immersed in the cooling liquid, and cooled.

Technical background of the invention and its problems In the process of manufacturing cables used as power transmission cables, communication cables, etc., generally, an extruder is used to obtain a desired shape and size (especially the outer diameter) from the die of the extruder. The size of the cable is extruded, and the heat generated in the cable in the step of extruding is removed by passing the cable through cooling water, and then the outer peripheral surface of the cable is dried. And have. In the above-described cable manufacturing process, a cable drying device having a mechanism called an air wiper is usually used in the process of drying the outer peripheral surface of the cable after being immersed in cooling water and cooled. To further explain the process of the cable drying device provided with the air wiper and the cable drying operation performed using the cable drying device, this type of cable drying device includes, for example, a compressor that pressurizes a gas such as air, A gas pipe for transferring air pressurized by the compressor, and an air wiper which is formed in an annular shape and has a plurality of gas ejection ports on the inner peripheral side and is configured to be connectable to the gas pipe. Having the step of drying the cable, the cable is immersed in cooling water and a water droplet of cooling water is attached to the outer peripheral surface of the cable is passed through a circular space formed by the air wiper, and a gas is discharged. This is done by removing the water droplets with the air jetted from the jet port.

By the way, in the cable drying device having the above-described configuration, the outer diameter of the cable passing through the circular space formed by the air wiper is equal to the diameter of the circular space. For a cable having a length of less than 50%, the efficiency of removing water droplets remaining on the outer peripheral surface of the cable by the air jetted from the gas outlet of the air wiper is significantly reduced by the present inventor. Etc. So, in view of the above facts,
Depending on the outer diameter of the cable extruded by the extruder, the outer diameter of the cable is smaller than the inner diameter of the air wiper.
It was conceived to newly introduce a step of replacing the air wiper so that the air wiper does not become less than 50%.

Therefore, the extruder for extruding the above-mentioned cable is
Since one device has the ability to produce a wide range of cables with an outer diameter of, for example, 30φ to 75φ, the inner diameter can be adjusted according to the outer diameter of the cable extruded by the extruder. In order to carry out the step of preparing air wipers which can be divided into a plurality of stages (for example, three stages of large, medium and small) and sequentially replacing these air wipers with a given cable, a new air wiper is set. Not only the work is required, but also the complicated work such as the work for connecting the gas pipe to each of the air wipers is required. Therefore, in order to avoid such a complicated work, an air wiper having an inner diameter that matches the largest diameter cable among the cables extruded by the extruder is attached in the end, and all the cables are attached by the air wiper. There is no choice but to carry out a drying operation, and as a result, malfunctions due to short circuits of various instruments caused by the inability to completely remove the water droplets remaining on the outer peripheral surface of the cable and ink for marking printing on the cable However, there is a problem in that it is not possible to prevent the occurrence of problems such as the mixing of water droplets.

OBJECTS Accordingly, the present invention was devised to improve the above-mentioned problems, and its purpose is to completely remove the droplets remaining on the outer peripheral surface of the cable. It is possible to prevent malfunctions such as short circuits of instruments and malfunctions such as the inclusion of droplets in the ink for marking printing on the cable, and of course, cable drying equipped with an air wiper that can also improve workability. It is to provide a device.

Means for Solving the Problems The above object is achieved by the cable drying device according to the present invention. In summary, the present invention provides a gas pipe for transferring a pressurized gas, and a gas pipe formed so as to surround the outer peripheral surface of a given cable, each of which is in communication with the gas pipe and is A divided air wiper having at least two gas jet outlets for ejecting the gas passing through the outer peripheral surface of the cable, and the position of the divided air wiper so as to fit the outer diameter of the given cable. A cable drying device having an adjusting mechanism for adjusting.
