Description

Outer yarn tension device

One, technical field

The utility model relates to textile machine, mainly relates to the device of the control yarn tension that the creel of twisting machine, loom uses.

Two, background technology

At the weaved cotton cloth tension force of range request control yarn of textile industry.Yarn is pulled and is arranged as warp from the yarn tube, and the even tension unanimity of warp, otherwise then cloth cover out-of-flatness of the cloth that weaves easily play bag.Chinese patent ZL02202473.5 discloses a kind of Creel tensioner, and the major technique feature is: a little axle is arranged, be installed with on the axle that " disk that has bearing, with the magnetic plate of iron forever, metal dish and nylon plate leave spacing between magnetic plate and the metal dish.Though it has better solved the even problem through line tension, but its tension force size relies on machinery adjustment, and is not too convenient.In addition, be only applicable to tyre cord, the purposes scope is less.

Three, summary of the invention

The purpose of this utility model is to overcome above the deficiencies in the prior art, provides a kind of scope of application bigger, and tension adjustment is convenient, the outer yarn tension device of compact conformation.

The utility model is achieved in that

A kind of outer yarn tension device comprises little axle 1, bearing 2; It is characterized in that: also have magnetic core 3, magnetic links 4, magnetic plate 5, coil rack 6 and coil 7, and housing 8; In housing: two bearings of magnetic core band are loaded on the little axle, an end face of magnetic core is provided with equally distributed double wedge 301, fixedly mount magnetic links on the little spindle nose of flank, leave spacing between the double wedge end face of magnetic core and the magnetic links, magnetic core is enclosed within the coil rack, coil is loaded on the skeleton outer shroud, and the magnetic plate that end face is provided with equally distributed double wedge 501 is housed between the outside of magnetic links and the housing, and its convex side and magnetic links join; Be fixedly linked with the housing of bolt 10 with magnetic core and outside, be fixedly linked with the housing of bolt with coil rack and outside, the lead-in wire of coil stretches out housing, and two and half housings are connected as one with bolt or rivet 9.

Above-described a kind of outer yarn tension device is characterized in that: reach equally distributed double wedge on the magnetic plate on the magnetic core, the number of teeth is identical, is all 10 teeth.

Above-described a kind of outer yarn tension device is characterized in that: be provided with hexagonal square hole 504 or square opening or tri-angle-holed at the center of magnetic plate, and be provided with through hole 801 at the center of corresponding shell.

The utility model is compared with background technology, has outstanding feature and effect is:

1, it is a kind of electromagnetic type tensioner, and the size of current of regulating winding can be adjusted the tension force size of tensioner easily.Thereby for loom, when changing different products, can require to change the tension force size of tensioner according to different weaving processes, change, adjust the tension force requirement, the quality of the product that assurance is woven to satisfy several kinds of weaving cotton cloth of weaving cotton cloth.

2, compact conformation, easy to install.

3, be applicable to that the use of various looms and twisting machine use, its purposes scope is wider.

Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Five, the specific embodiment

Fig. 1 is extremely shown in Figure 2, outer yarn tension device.It comprises little axle 1, bearing 2, magnetic core 3, magnetic links 4, magnetic plate 5, coil rack 6 and coil 7, and housing 8.In housing: two bearings of magnetic core band are loaded on the little axle, and an end face of magnetic core is provided with equally distributed double wedge 301, and the little axle on flank limit is gone up the fixed installation magnetic links, leaves spacing between the double wedge end face of magnetic core and the magnetic links, promptly leaves the gap between them; Magnetic core is sleeved in the coil rack, and coil is loaded on the skeleton outer shroud; Between the outside of magnetic links and the housing magnetic plate is housed, also is provided with equally distributed double wedge 501 on the side end face of magnetic plate, convex side and magnetic links join.The hole of passing on the magnetic plate with bolt 10 503 is fixedly linked magnetic core and outside housing on one side, and another side directly is fixedly linked magnetic core and outside housing with bolt.With tapping screw and the opening 502 that passes on the magnetic plate coil rack and outside housing are fixedly linked, the lead-in wire of coil is drawn from the pressing trough of shell rim, and two and half housings are connected as one with bolt, nut or tubular rivet.

Fig. 3 is to shown in Figure 6, and the double wedge quantity of establishing on the double wedge of establishing on the magnetic core end face and the magnetic plate end face is identical, preferably is made as 10 teeth.Be provided with hexagonal square hole 504 at the center of magnetic plate, also can be square opening or tri-angle-holed.And the center of corresponding shell is provided with through hole 801.

The outer yarn tension device that the utility model provides, little axle 1 is in magnetic core 3, and magnetic links 4 relatively rotates between magnetic core double wedge 301 end faces and magnetic plate double wedge 501 end faces, and after supplying direct current to coil 7, magnetic core produces magnetic force, and magnetic core is inhaled magnetic plates 5 by magnetic links 4.The double wedge of the double wedge of magnetic core end face and magnetic plate end face is interlaced, and produce magnetic damping on the magnetic links between them, stop relatively rotating each other, promptly produce the moment of resistance, adjust the stream size of powering of coil, just can adjust the size of the moment of resistance, thereby realize the adjustment of the tension force size of outer yarn tension device.And be located at the hexagonal square hole 504 at magnetic plate center, with the hexagonal spanner rotation magnetic plate that inserts in the hole, the double wedge 501 on the adjustment magnetic plate and the relative rotation position of the double wedge 301 on the magnetic core, make that the position of double wedge is interlaced between them, also can be used for changing the magnetic line of force that passes on the magnetic plate simultaneously and carry out the fine setting of tension force.
