Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0020] Such as figure 1 or figure 2 As shown, in order to achieve the above purpose, the present invention provides a water-blocking yarn pay-off frame, which includes a frame body 100 and a rotating support 200. The rotating support 200 is axially and radially positioned and can be freely positioned in the circumferential It is rotatably installed on the frame body 100 , and the rotatable support 200 is used for fixing and installing the water-blocking yarn bobbin 300 .

[0021] The above-mentioned water-blocking yarn pay-off frame, because the water-blocking yarn bobbin 300 is fixedly installed on the rotating support 200, the rotating support 200 is installed on the frame body 100 in the axial and radial directions; The radial direction is positioned, and the water-blocking yarn bobbin 300 cannot move in the axial and radial directions of the rotating s...

Abstract

The invention discloses a water-blocking yarn pay-off frame, which includes a frame body and a rotating support. Used for fixed installation of water blocking yarn bobbins. Since the water-blocking yarn bobbin is fixedly installed on the rotating support, the rotating support is axially and radially positioned on the frame body; since the axial and radial directions of the rotating support are positioned, the water-blocking bobbin cannot rotate The support moves axially and radially, thereby avoiding the problem of water-blocking powder falling off from the yarn caused by the water-blocking bobbin moving. And in the process of paying off, the water-blocking yarn bobbin will rotate and pay-off due to the force of the yarn, which can prevent the water-blocking powder on the yarn from being scraped off when the yarn passes through the guide wheel or the distribution disc in a tensioned state. Therefore, the yarn entering the cable has more water-blocking powder, so that the water-blocking cable has a better water-blocking effect.

Description

technical field [0001] The invention relates to a pay-off frame, in particular to a water-blocking yarn pay-off frame. Background technique [0002] In recent years, the variety of wire and cable has shown a trend of diversification, and has developed from simple power transmission to multi-function. Water blocking requirements for power cables have only been developed in recent years. In the past, cables with water blocking requirements were mainly limited to submarine cables, ultra-high voltage cables and communication cables. [0003] With the deepening of the research and understanding of insulation water absorption and water tree, people are more and more aware of the importance of waterproof performance for medium and high voltage power cables. In areas with high groundwater levels or perennial rainy areas (such as the area south of the Yangtze River in China), more and more users have put forward waterproof requirements for cables, so the demand for water-blocking ca...
