Abstract
The invention relates to a tension detection frame with a flex function. In order to overcome the problems that the dynamic tension in the prior belt material conveying process is difficult to be controlled and the space is required to be dense sometimes, the invention provides the tension detection frame with the flex function. The tension detection frame consists of two guide rollers, a detection roller, an air cylinder and a position sensor; by adopting the flex function of the air cylinder, the tension fluctuation of the tension caused by the start, stop and acceleration in the belt material conveying process can be relieved and absorbed; the tension detection frame can effectively solve the stable control problem of the dynamic tension in the belt material conveying transmission process; meanwhile, the tension detection frame has small volume.
Description
Affiliated technical field the present invention relates to a kind of tension detecting rack, especially a kind of tension detecting rack with Telescopic.
Background technology
At present, a lot of occasions require the conveying of strip will keep tension stability, with the precision that guarantees converted products and stable, common tension-detecting mechanism has: the pendulum roller type tension detecting device, Cantilevered tension force testing apparatus and dual-arm supported tension detecting device etc., Cantilevered tension force testing apparatus and dual-arm supported tension detecting device are owing to easily cause strip in starting without any buffer gear, stop, the instability of Tension Control in acceleration and the moderating process, the dynamic property of Tension Control is bad, the pendulum roller type tension detecting device can obtain higher tension force dynamic control performance comparatively speaking because of the storing function is arranged, can solve preferably in the strip transmission and quicken, the tension force of deceleration and shutdown process is steadily controlled, so but this mode is because need reserve swing space mechanism by the pendulum roller is taken up space greatlyyer, this problem is just more outstanding when the device space is limited.
Summary of the invention
Dynamic tension is restive in the existing band material course of conveying needs compact problem sometimes with the space in order to overcome, the invention provides a kind of tension detecting rack with Telescopic, this tension detecting rack is by two deflector rolls, a measuring roll, a cylinder and a position transduser are formed, measuring roll is installed on the take-off lever of cylinder, the measuring roll secured in parallel is in the cylinder top, the feeler lever of measuring roll connection location sensor, utilize the Telescopic of cylinder alleviate with absorption band material course of conveying in because of starting, stop, the tension fluctuation that quickens and slow down and bring, this tension detecting rack can solve the stable control problem of dynamic tension in the band material course of conveying effectively, and the volume of this tension monitoring frame is less simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: this tension detecting rack is by two deflector rolls, a measuring roll, a cylinder and a position transduser are formed, measuring roll is installed on the take-off lever of cylinder, the measuring roll secured in parallel is in the cylinder top, the feeler lever of measuring roll connection location sensor, the signal output of sensor and the proportional relation of the height of measuring roll, change the pressure that feeds gas in the cylinder with pressure regulating valve, the pressure of gas and the proportional relation of tension force that measuring roll makes progress in the cylinder, when strip is walked around deflector roll and measuring roll and is carried, set the size of strip tension force with pressure regulating valve, the closed loop adjustment rewinding or the discharge mechanism that utilize tension control assembly and sensor to form, make measuring roll be in the midway location of cylinder stroke always, utilize the Telescopic of cylinder take-off lever alleviate with absorption band material course of conveying in because of starting, stop, the tension fluctuation that quickens and slow down and bring, this tension monitoring frame can solve the stable control problem of dynamic tension in the band material course of conveying effectively, and the volume of this tension monitoring frame is also smaller simultaneously.
The invention has the beneficial effects as follows the Telescopic that in band material course of conveying, utilizes cylinder alleviate with absorption band material course of conveying in because of starting, the tension fluctuation that stops, quicken and slow down and bring, for the band material is provided by the Tension Control means that provide dynamic stability compact, because the technical measures that this invention is taked all are mature and feasible, so be not difficult to realize.
