Embodiment 2
Conceived based on same invention, another aspect of the present invention, as shown in Figure 2, there is provided a kind of calendered product thickness control
Device processed, including tension sensor 60, dance roller 50 and speed encoder 70, rolled material are arranged on a rolled material
In volume 20, pass sequentially through the dance roller 50, the tension sensor 60 and the speed encoder 70 and enter afterwards
Calender gap between quick roll 40 and slow roll 30, the dance roller 50, the tension sensor 60 and the calendering
The motor of material volume 20 forms closed-loop tension control；The motor shape of the speed encoder 70, the slow roll 30
Control is closed into the speed ratio between the quick roll 40 and the slow roll 30.
Wherein, the dance roller 50, the tension sensor 60, the speed encoder 70 and some transition rollers
80 are arranged on same installation base plate 11, rolled material volume 20 pass sequentially through the dance roller 50, described
Force snesor 60, the speed encoder 70 and the transition roller 80 enter the quick roll 40 and the slow roll 30 it
Between calender gap.
Wherein, it is provided with the slow roll 30 on diaphragm 33 and the quick roll 40 and is provided with mould release membrance 42, is passed through
The calendered product that the calender gap is formed is carried on the mould release membrance 42.
Wherein, the slow roll 30 is arranged in two pairs of rollers installation pedestal 10 by a slow roll adjustable support 31, described fast
Fast roller 40 is arranged in two pairs of rollers installation pedestal 10 by a quick roll mounting bracket 41, the slow roll 30 and the quick roll 40
It is mounted opposite to form the calender gap.
Wherein, the force component 32 of the slow roll adjustable support 31 connection one, the force component 32 adjust it is described at a slow speed
The calendering gap between roller 30 and the quick roll 40.The force component 32 can be cylinder, motor or other can be with
Realize the power set of linear displacement.
The specific work process of calendered product thickness control device is as follows：
First, the diaphragm 33 being mounted on slow roll 30 only shield (tape running speed with the fast ratio of two pairs of rollers change
Change and change)；The mould release membrance 42 being mounted on quick roll 40 carries calendered product and enters next process (constant airspeed).Due to
The off-type force of two kinds of films is different, and calendered product is adhered to 100% above the mould release membrance 42 being mounted on quick roll 40.Based on
On premise, as long as control the material before calendering tension force and speed with regard to the thickness of calendered product can be controlled.
Tensioned regulating roller 50 and tension force pass between rolled material unreels stack (quick roll 40 and slow roll 30)
Sensor 60 controls unwinding tension, and the speed for unreeling speed is controlled by dance roller 50, and tension sensor 60 detects the big of tension force
It is small.When tension force fluctuates, system can adjust according to the fed back values of tension sensor 60 to unreeling speed, finally reach
To the constant of tension force.
Speed encoder 70 detects the tape running speed of material, while the motor group of speed encoder 70 and slow roll 30
Into closed-loop control.Because the speed of quick roll 40 is constant, calendered product 100% is adhered on mould release membrance again, so working as speed
Encoder 70 detects that rolled material pan feeding speed is thickening toward discharge thickness after explanation calendering during great fluctuation process, at this moment due to slow roll
30 motor is closed-loop control with speed encoder 70, and motor will automatically turn down the rotating speed increase He of quick roll 40
Speed between slow roll 30 is than reducing the thickness to be discharged after calendering.Slow, say conversely, speed encoder 70 detects to unreel
Material thickness is thinning after bright calendering, and motor will rev up automatically, makes the speed of quick roll 40 and slow roll 30 than reducing,
The thickness of material after increase calendering.The balance between input and output material is finally reached to control the uniformity of material thickness after calendering.
Embodiments of the present invention are explained in detail above in association with accompanying drawing, but the invention is not restricted to described implementation
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen within protection scope of the present invention.
