Description
Technical field
The utility model relates to the roller roller of textile machine, is specifically related to the outer yarn tension device of straight twister in a kind of spinning machinery.
Background technology
Warping machines in the existing textile machine, the warp thread of drawing from bobbin cradle passes collection filament plate, spreader, and rich overtension roller roller is rich on axle, and is rich in controlling by the tensioner on the creel through the warp tension on the axle.At present, tensioner is made of magnetizing coil, B-H loop etc., is the disclosed a kind of outer yarn tension device of 200320131609.X as China Patent No..Comprise little axle, bearing, magnetic core, magnetic links, magnetic plate, coil rack and coil and housing etc.In housing: magnetic core has two bearings and is loaded on the little axle, an end face of magnetic core is provided with double wedge, fixedly mount magnetic links on the little spindle nose in the side of double wedge, leave spacing between tooth and the magnetic links, adorn magnetic plate between magnetic links and the housing, magnetic core is sleeved in the coil rack, coil is loaded on the skeleton outer shroud, magnetic core and housing are fixedly linked, and skeleton and housing are fixedly linked, and magnetic links and magnetic core double wedge end face and magnetic plate relatively rotate.Produce magnetic force by coil for magnetic core behind the direct current, attract magnetic plate, form the magnetic damping and the moment of resistance, control and adjust the size of tension force.Tensioner connects and band roller roller produces tension force to warp thread.Slightly not enough is to leave spacing between tooth and the magnetic links, needs during assembling to adjust, and acquires a certain degree of difficulty and workload.And its volume ratio is bigger, and structure is more complicated also.
Summary of the invention
The purpose of this utility model provides a kind of structure simpler compactness at above the deficiencies in the prior art, and volume is little, installs and adjusts the outer yarn tension device of more convenient straight twister.
The technical solution of the utility model is achieved in that the outer yarn tension device of a kind of straight twister, comprises little axle, bearing, magnetic core, coil, magnetostatic steel sheel; Be characterized in: have little axle on the magnetic core, little axle go up that tape spool holds and the hinge of packing in, hinge is provided with B-H loop, B-H loop and magnetostatic steel sheel and magnetic core cylindrical leave the magnetic field air gap, be Crossed Circle magnetic field air gap, on the magnetic core coil be housed and injection moulding becomes one, draw lead from coil, hinge is fixed on the little axle of magnetic core by nuts and washers, and magnetostatic steel sheel is fixed on the magnetic core by screw; Hold gear by in the gland with hinge on rib-loop be fixed on the hinge head; Coil power supply, magnetic core produces magnetic force, forms the magnetic damping and the moment of resistance in the magnetic field air gap between magnetic core and B-H loop and the magnetostatic steel sheel.
The electric current of control and adjustment coil power supply changes the size of the moment of resistance.The excitatory of coil can be single closed magnetic circuit, and the excitatory of coil also can be two closed magnetic circuits.
The outer yarn tension device of a kind of straight twister that the utility model provides is compared with background technology, and it is more simple compact to have structure, and volume is less, manufacture craft is simple, saves material, and manufacturing cost is lower, easy to assembly, advantage such as rate of breakdown is lower is as the outer yarn tension device of straight twister.
