Fig. 3 is fundamental diagram of the present utility model.
Each list of reference numerals is among the figure: 1, base, 2, bracing frame, 3, unreeling shaft, 4, brake disc, 4-1, annular groove, 5, material, 6, slipper, 7, arm shaft, 8, swing arm, 9, support wheel shaft, 10, support wheel, 11, regulate wheel shaft, 12, adjusting knurl, 13, Scroll, 14, material volume, 15 material volume core.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model and flexible material unwinding equipment coupling, described flexible material unwinding equipment comprises the parts such as base 1, bracing frame 2, unreeling shaft 3, support wheel shaft 9, support wheel 10, Scroll 13 material volume 14 and material volume core 15, wherein, bracing frame 2 is fixed on the base 1, unreeling shaft 3, support wheel shaft 9 and Scroll 13 are fixed on the bracing frame 2, and material volume core 15 is fixed on the unreeling shaft 3 together with material volume 14, brake disc 4, and they can also can only rotate together.
Referring to Fig. 1, Fig. 2, the utility model comprises brake disc 4, slipper 6, swing arm 8, arm shaft 7, adjusting knurl 12 and regulates wheel shaft 11, described brake disc 4 is fixedly mounted on unreeling shaft 3 one ends of material unwinding equipment, brake disc 4 is equipped with swing arm 8, described slipper 6 is installed in the swing arm 8, described swing arm 8 is hinged with the bracing frame 2 of material unwinding equipment by arm shaft 7, and described adjusting knurl 12 is installed in to be regulated on the wheel shaft 11, and described adjusting wheel shaft 11 is fixed on the end of swing arm 8.
Referring to Fig. 3, principle of work of the present utility model is: when material 5 tension force were suitable, swing arm 8 was in balance position, and the friction brake force between brake disc 4 and the slipper 6 and the tension force of material 5 are in state of equilibrium; Unreel the increase of disturbance tension force in the process along with material, the swing arm moment balance state that is hinged on the material unwinding equipment bearing support 2 is destroyed, and material 5 holds up adjusting knurl 12, and rocking arm 8 is around arm shaft 7 counter-clockwise swings, the pressure between slipper 6 and the brake disc 4
F1Reduce, friction force reduces thereupon, and unreeling shaft 3 rotating speeds of material unwinding equipment increase, so that the tension force of material 5 reduces.Above-mentioned control process can be expressed as:
Otherwise:
This shows through above-mentioned feedback procedure, the tension force of material 5 is controlled on the constant numerical value.
The positive pressure that is equipped with between Moving plate 4 and the slipper 6 is
F1, swing arm 8 is in the situation that a gravitate, and the unbalanced moment of arm shaft 7 is M, obtains according to the moment balance relation:
Wherein
Be tension force at the component of arm shaft tangential direction,
fThe tension force of material.
Because unreeling shaft moves with uniform velocity, obtain according to the moment balance relation:
，
Wherein
kThe friction coefficient between brake disc and the slipper,
RThe radius of brake disc 4,
R 1 It is the radius of material volume 14.
Above two formulas of arrangement get:
Therefore, at angle
aNot in the very large situation
,
So
, the radius of material volume 14
R 1 For tension force
fImpact can ignore.
This shows, change the size (as shown in phantom in Figure 3, angle becomes α 1) that the position of regulating wheel shaft 11 can change angle [alpha], just can change tension force.When the position of regulating wheel shaft 11 immobilized, the size of material tension force also immobilized, and the utility model is regulated by the reaction type to material tension force according to above-mentioned principle of work, had realized permanent tension force control.
