Abstract
The utility model relates to a magnetic tension device for a weft storing device, which is composed of a left tension disk, a right tension disk and a porcelain tube, wherein the left tension disk is a non-magnetic tension disk; the right tension disk is a magnetic tension disk; the left side of the left tension disk is provided with magnetic steel; the porcelain tube is arranged on a mandrel; the magnetic steel is arranged on a tensioning device. The utility model can improve the weft tension, so that the weft tension is uniform and changeable. The utility model has the advantage of long service life.
Description
The utility model relates to the tensioner that uses on a kind of weft accumulator, especially a kind of magnetic tensioner.
The tensioner that uses has pagoda type tensioner and sheet spring formula tensioner now.The tension force of pagoda type tensioner is to produce tension force by corrective action helical spring compression on tension pulley, because the winding of this spring is than big, the spring Coil-up difficulty, and spring when making end face be difficult for parallel, and in use, spring can rotate together along with tension pulley, so tension force is inhomogeneous.Though sheet spring formula tensioner can be adjusted and stable tension force by the sheet spring, big, easy to wear, the easy fluffing of sheet spring formula tensioner volume, play groove, and the heat treatment of reed is had very high requirement.
Goal of the invention of the present utility model is to provide a kind of magnetic tensioner that can improve weft tension and compact conformation.
The utility model is a kind of magnetic tensioner that is used for weft accumulator, be made up of left tension pulley 1, right tension pulley 2 and porcelain tube 3, left tension pulley 1 and right tension pulley 2 are located on the porcelain tube 3, and left tension pulley 1 is non magnetic tension pulley, right tension pulley 2 is the magnetic tension pulley, is provided with magnet steel 4 in the left side of left tension pulley 1.
Compared with prior art, the utlity model has following advantage:
1. the utility model is by the suction of magnet steel to the generation of magnetic tension pulley, make and be clipped in weft yarn generation tension force between magnetic tension pulley and the non magnetic tension pulley, because the suction that magnet steel produced is even, therefore, the clamping force that makes magnetic tension pulley and non magnetic tension pulley act on weft yarn keeps evenly, cause the tension force of weft yarn to keep evenly thus, thereby improved the tension force of weft yarn, and have the advantage of compact conformation.2. since the utility model magnet steel is located on the tensioning device, so can be as required, realize the adjustment of weft tension by the distance between adjustment magnet steel and the magnetic tension pulley, so, the utlity model has the adjustable advantage of tension force.
3. since the utility model in its use, magnetic tension pulley and non magnetic tension pulley can be followed weft yarn and be rotated, so the utility model can improve its service life, have the little advantage of wearing and tearing.
