Embodiment:
Explanation that the utility model will be further described in conjunction with the accompanying drawings:
The utility model is made up of support 1, tension control mechanism, stubble warning device mechanism and mistake wire carrier.See accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, tension control mechanism of the present utility model is made up of ratchet 12, ratchet 11, ratchet fixed axis 13, ratchet extension spring 14, bowl-type mandrel 38, plane scroll spring 39, band tooth revolving sleeve 36, curve of equal velocity cam 34, little guide wheel 23, little guide wheel shaft 21, profile of tooth clamp 33, clamp fixed axis 27, clamp torsion spring 26, eccentric fixed block 32 and drag board 28.Ratchet 11 is fixed on the support 3 through ratchet fixed axis 13, is subjected to ratchet extension spring 14 effects to hook ratchet 12.Bowl-type mandrel 38 is fixed on the support 3.Little guide wheel 23, little guide wheel shaft 21, profile of tooth clamp 33, clamp fixed axis 27, clamp torsion spring 26, eccentric fixed block 32 are loaded on the curve of equal velocity cam 34.Band tooth revolving sleeve 36 is enclosed within on the bowl-type mandrel 38 cylindrical fixed constant velocity curve cam 34.Plane scroll spring 39 is loaded in the bowl-type chamber of bowl-type mandrel 38, and an end is fixed on the bowl-type mandrel 38, and the other end is fixed on the band tooth revolving sleeve 36.Drag board 28 is fixed on the support 3 through bearing 35, and an end is equipped with bearing 25 and fits with curve of equal velocity cam 34, and the other end withstands the screw on the ratchet 11.During normal the braiding, braided wires on the drum 1 such as the tension of accompanying drawing 2 threading, when tension force on the line during greater than default tension force, curve of equal velocity cam 34 is resisted plane scroll spring 39 torsion and is rotated, promote drag board 28 swings, drive ratchet 11 and overcome the swing of ratchet extension spring 14 pulling force, make the unwrapping wire braiding that gets loose of ratchet 12 and ratchet 11.When tension force was less than default tension force on the line behind the unwrapping wire, constant speed curve cam 34 was toward back rotation under plane scroll spring 39 twisting forces, and ratchet 11 backswing under ratchet extension spring 14 tension makes ratchet 12 and ratchet 11 engagements, and unwrapping wire stops.Under this goes round and begins again action, finish the unwrapping wire braiding of stablizing under the tension force.
When presetting tension force, see accompanying drawing 2, accompanying drawing 3, unclamp and rotate eccentric fixed block 32, outwards swing profile of tooth clamp 33 again and throw off with band tooth revolving sleeve 36, rotating band tooth revolving sleeve 36 is adjusted plane scroll spring 39 to the pre-torsion that is fit to, swing profile of tooth clamp 33, with 36 engagements of band tooth revolving sleeve, and rotate and fixing eccentric fixed block 32, make it to withstand profile of tooth clamp 33.Because of plane scroll spring 39 has the advantages that to store more energy in smaller volume, be fit to very much of the requirement of the wire rod feedway of medium-sized high-speed knitter to this type of spring.And regulate plane scroll spring 39 with band tooth revolving sleeve 36, it is more accurate that laying tension is regulated.
Stubble warning device of the present utility model mechanism is made up of horizontal guide wheel 55, alarm board 53, spring pull bar 51 and warning torsion spring 52.See accompanying drawing 2, horizontal guide wheel 55 and the same screw of alarm board 53 usefulness are connected on the frame 3.Warning torsion spring 52 1 ends block frame 3, one ends and block alarm board 53.Spring pull bar 51 1 ends link to each other with curve of equal velocity cam 34, and an end links to each other with alarm board 53.During normal unwrapping wire, alarm board 53 is inclined at warning torsion spring 52 twisting force lower swings; When fracture of wire, curve of equal velocity cam 34 returns starting point under plane scroll spring 39 twisting forces, drive spring pull bar 51 promotion alarm boards 53 overcome warning torsion spring 52 torsion and are erectility, touch the external sensing chip of high-speed knitter, reach the purpose of stubble warning device.
