Embodiment
Provide the preferred embodiment of the utility model below in conjunction with Fig. 1 to Fig. 3, to specify the technical scheme of the utility model.
As shown in Figure 1; Comprise annealing body of heater 2; Be located at the tensioning roller group 4 and outlet side tensioning roller group 1 of annealing body of heater 2 inlet sides respectively, travelling belt steel 14 also comprises the gear 3 between annealing body of heater 2 inlets and inlet side tensioning roller group 4 through the frequency control motor of tensioning roller group.Each is made up of said tensioning roller group four rollers.Per two rollers partner, and make through the band steel 14 of tensioning roller group S-shaped.Its role is to increase the cornerite between band steel 14 and the tensioning roller, enlarge contact surface, improve the precision of tension force preset value.Wherein, every tensioning roller is by frequency control motor its speed of control and moment of torsion.
As shown in Figure 2, gear 3 comprises: stationary roll 6, dancer roll 9, dynamometry roller 5, guide deflection sheave 7, servomotor 15, slide mechanism.Wherein, two stationary rolls 6 are installed on the frame through bearing respectively, and dancer roll 9 is between two stationary rolls 6, and guide deflection sheave 7 is installed on the frame directly over the dancer roll 9 through bearing, and guide deflection sheave 7 and servomotor 15 be coaxial to be connected and by driven by servomotor.Servomotor 15 receives the variable signal that pressure transmitter 13 causes because of tension fluctuation, and timely and preset value compares, and controls through driving the displacement up and down of 7 pairs of dancer rolls of guide deflection sheave.In addition; Guide deflection sheave 7 outer rims are provided with gear; Drag chain 16 pile warp guide deflection sheaves 7 are meshed with gear on it, and dynamometry roller 5 is movably arranged in the dynamometry frame 12, and dynamometry frame 12 1 ends are movably arranged on the frame through bearing pin 11; The other end contacts with pressure transmitter 13 on being fixed on frame, two stationary rolls 6 of band steel pile warp, dancer roll 9, dynamometry roller 5; And the position of dancer roll 9 will change the band steel and pass through the path, through the regulation and control of servomotor 15, dancer roll 9 accurately locate, be with tensioning and the relaxed state of steel 14 between outlet side tensioning roller group 1 and inlet side tensioning roller group 4 thereby controlled.
As shown in Figures 2 and 3, slide mechanism comprises: be fixed on the chute on the frame, the slide block 10 that is connected with drag chain 16; Slide block 10 can move up and down along chute, and drag chain 16 1 ends are connected with slide block 10, and the other end is connected with counterbalance weight 8; The effect of counterbalance weight 8 is the deadweight of balance-jitter roller 9, and to reduce the load of servomotor 15, dancer roll 9 is movably arranged on the slide block 10 through bearing; Can guarantee dancer roll 9 rotation down in working order like this, can guarantee again that when tension fluctuation drag chain 16 affects slide block to move up and down; Move up and down thereby drive dancer roll, carry out tension compensating and adjustment.
The realization principle of the utility model is: the tension force preset value of complete assembly is accomplished by inlet side tensioning roller group 4 and outlet side tensioning roller group 1; Servomotor 15 also preset one with the suitable set(ting)value of annealed strip 14 normal tensions; Band steel 14 forms inverted U-shaped shape between stationary roll 6 and dancer roll 9, the displacement of dancer roll 9 is determining the tensioning degree with steel 14.In the real work, band steel 14 is because of the bad tension fluctuation that causes of plate shape, and the variation of tension force size causes the dynamometry roller to bear different pressure; And give pressure transmitter 13 through the pressure transmission that dynamometry frame 12 bears dynamometry roller 5, the variable signal of this belt transect steel tightness is by pressure transmitter 13 actual measurements and send into servomotor 15; When measured value during greater than set(ting)value, servomotor 15 is rotated counterclockwise, because guide deflection sheave 7 and 15 coaxial connections of servomotor; Therefore guide deflection sheave 7 is rotated counterclockwise, and the gear of drag chain 16 pile warp guide deflection sheaves 7 outer rims is under the effect of engagement; Drag chain 16 moves down, and the slide block 10 that is connected with drag chain 16 moves down, and drives dancer roll 9 and moves down; Band steel 14 tension force reduce, and when tension force is reduced to when coincideing with set(ting)value, servomotor 15 stops operating.When measured value during less than set(ting)value, whole process is then opposite.
Though, the embodiment of the utility model has more than been described, it will be understood by those of skill in the art that these only illustrate, under principle that does not deviate from the utility model and essence prerequisite, can make numerous variations or modification to embodiment.Therefore, the protection domain of the utility model is limited appended claims.
