Basic tension, ensure core rope straightness other than, the tension of core rope can also directly influence length, pitch of final products etc.
Parameter.
In addition, according to product difference, up to 100 strands or more of the core rope that some products are arranged simultaneously, if every core rope
Tension is inconsistent, may result in that product flatness that final production goes out, straightness receives greatly influences.
The mode for commonly using control core rope tension on the market at present is to hold out against the mode of brake block using cylinder to provide one
Relative constant resistance, but due to brake block abrasion condition difference, per reasons such as disc core rope coil diameter differences, can all influence tension
Uniformity causes product the problems such as steel wire is uneven, and flatness is inadequate occur.
Utility model content
The utility model technical issues that need to address are：It is carried in a manner that cylinder holds out against brake block in the prior art

Reason can all influence the uniformity of tension, and product is caused the problems such as steel wire is uneven, and flatness is inadequate occur.
The utility model takes following technical scheme：
A kind of lever paying-off control device, including draw drum, movable pulley mechanism, lever, counterweight, slide rheostat, core
Rope；The core rope is drawn from draw drum, and by movable pulley mechanism；Draw drum variable-ratio；Connect below movable pulley mechanism with lever
It connects, described lever one end is hinged end, and the other end is free end, and being capable of facade swing；Have along its length on the lever
There is multiple be used for and the fixed bit with reconnection；The slide rheostat is slidably connected with movable pulley mechanism, can detect movable pulley
The vertical position of mechanism, and pass through controller and connect with patchboard signal.
Further, the movable pulley mechanism lower part is flexibly connected by connecting rod with lever.
Further, the core rope is the core rope of polyurethane synchronous belt.
A kind of control method of above-mentioned lever paying-off control device, state one：When 2 times of core rope tensions are more than counterweight forces
The lower pulling force that square provides, movable pulley can rise；State two：When 2 times of core rope tensions are less than the lower pulling force of counterbalance moment offer, dynamic cunning
Wheel can decline；Slide rheostat monitoring movable pulley position, output signal via controller are converted into corresponding electric signal and pass to
Unwrapping wire motor；Unwrapping wire motor is regulated the speed in real time, state for the moment accelerate loosen, state two when slow down tense, control movable pulley machine
Structure in setting position, realizes the accurate control to core rope tension always.
The beneficial effects of the utility model are：
1) it can realize to accurately being controlled per one core wire tension.
2) lower pulling force can be provided by replacing counterweight or selection counterweight link position different from lever, so as to
Tension is accurately controlled, the accuracy of tension force is high.
3) will not be there is a situation where wearing during use, service life is long, and it is high to measure consistency.
4) it is ingenious in design, it is verified by test of many times, can realize and the tension per one core wire is accurately controlled.
5) have a wide range of application, can be used as and synchronous belt production line laying tension is controlled, simultaneously can be used for all kinds of needs
