When the yarn tube was reeled, yarn passed yarn clamping passage, incipient stage; Swing arm becomes laterally, and lead-in wire also becomes laterally to draw movable part, and lead-in wire is axially consistent with the sense of motion of movable part; The application force of lead strain on the movable part sense of motion equals lead strain, also just equals weight gravity.Along with coiling carries out, yarn tube diameter changes from small to big, and bobbin bank is upwards lifting gradually; Drive the swing arm left end and rise, make to go between and the horizontal angle that forms, lead-in wire sense of motion axial and movable part forms angle; Then the application force of lead strain on the movable part sense of motion be less than lead strain, promptly less than the gravity of weight, along with the swing arm left end rises gradually; Lead-in wire angle axial and the movable part sense of motion strengthens gradually, and the application force of lead strain on the movable part sense of motion diminishes gradually, and movable part also just diminishes to the clamping friction force of yarn gradually; Yarn tension is diminished gradually, guarantee the yarn tube profile of shaping and the homogeneity of density.
Supplementary sum as to technique scheme is perfect, and the utility model also comprises following technical characterictic.
Described yarn tensioner also comprises spring, and spring one end connects described swing arm, and the other end connects frame, for the decline of swing arm resets elastic force is provided, and drops in swing arm spacing bearing force is provided when horizontal.
The supporting member of described friction mechanism is plates, and movable part is similarly plates, on supporting member and the movable part through hole is set; Guide is the hollow bobbin; Guide passes the through hole of supporting member and movable part, and mandrel is threaded onto the guide hollow cavity, and lead-in wire is connected with movable part through mandrel.
Described friction mechanism is a gate-type; Groove is set respectively on the opposite face of supporting member and movable part front end; Two grooves form yarn clamping passage relatively, and supporting member and movable part rear end flexibly connect through the bearing pin as guide, and movable part can be rotated around guide; Supporting member and movable part front end are crisscross arranged, and the movable part front end is connected with lead-in wire.
Further, described supporting member and movable part front end are grid.
Described weight is made up of counterweight mandrel and the counterweight counterweight that is sleeved on the counterweight mandrel, how much can regulate weight gravity through adjustment counterweight counterweight.
Described swing arm left end supports through bearing pin runner is installed, and described lead-in wire is around in runner.
Use the utility model can reach following beneficial effect: the utility model changes the application force of lead-in wire to the movable plate of friction mechanism through the swing arm of going up and down with bobbin bank is set; Realize that movable plate is variable to the friction force of yarn; Reach variable tension, guaranteed the yarn tube profile of shaping and the homogeneity of density.
