Automatic tension adjuster for water blocking yarn production

Abstract

The invention discloses an automatic tension adjuster for water blocking yarn production. The problems that an existing automatic tension adjuster does not have the function of water blocking yarn back rolling and rotating shaft automatic clamping. The adjuster comprises a worktable, a paying-off roller is arranged on one side of the worktable, a yarn along roller is arranged on one side of the paying-off roller, a base is fixed to the center of the top of the worktable through a bolt, a supporting plate is fixed to one side of the top of the base through welding, a back-roll roller is arranged on the center of the side, close to the paying-off roller, of the supporting plate, a protection cover is fixed to the other side of the supporting plate through a bolt, the inner wall of one side of the protection cover is fixedly provided with a variable-frequency speed adjuster through a bolt, an output shaft of the variable-frequency speed adjuster is connected with an input shaft of a magnetic powder tensioner on one side, an output shaft of the magnetic powder tensioner is connected with the back-roll roller through a rotating shaft, the other side of the rotating shaft is provided with a clamping mechanism, a speed adjuster is arranged on one side of the top of the worktable, and the speed adjuster is electrically connected with the magnetic powder tensioner and the variable-frequency speed adjuster.

Description

technical field [0001] The invention relates to the technical field of water-blocking yarn production, and specifically relates to an automatic tension adjuster for water-blocking yarn production. Background technique [0002] In the application of power cables, the cables are usually laid in direct burial, cable trenches, tunnels, etc., which inevitably come into direct contact with water, and may even be soaked in water for a short or long time, causing moisture to slowly penetrate into the cable. General cable insulation materials, in After the cable is used for a period of time, water tree phenomenon will be formed. When the water tree grows to a certain extent, it will cause the cable to break down. Therefore, water blocking yarn must be used. However, the existing automatic tension adjuster for water-blocking yarn production does not have the problems of rewinding water-blocking yarn and automatic clamping of the rotating shaft. [0003] Therefore, how to design an au...
