The technical scheme that solves the problems of the technologies described above is:
A kind of metal rolled piece coiling tension measurement mechanism, it comprises drive motors, reductor, reel, they connect successively, its improvements are, it also has movable floor, fixed base plate, pulling force sensor, deformeter, digital display and computer, drive motors, reductor, reel is fixedly mounted on the movable floor, the outer end of movable floor connects an end of pulling force sensor, the other end of pulling force sensor is connected with fixture, movable floor is positioned on the fixed base plate, between movable floor and the fixed base plate for being rotatably connected, the signal output part of pulling force sensor and deformeter, digital display, computer connects successively, and the signal output part of computer is connected with the control device of drive motors.
Above-mentioned metal rolled piece coiling tension measurement mechanism, a side of described movable floor and fixed base plate has corresponding vertical rotational axis hole and rotating shaft, and rotating shaft is installed in the rotational axis hole, and rotational axis hole and rotating shaft are for being rotatably connected.
Above-mentioned metal rolled piece coiling tension measurement mechanism has needle roller between the lower face of described movable floor and the upper face of fixed base plate.
Adopt the metal rolled piece coiling tension measurement mechanism of this structure; drive motors; reductor; reel is fixedly mounted on the movable floor; movable floor is born and is all batched pulling force; pulling force sensor is connected an end of movable floor; pulling force is sent to deformeter; deformeter amplifies measurement result; deliver to digital display through the dividing potential drop scale conversion, directly show the tension force size, enter computer through the A/D conversion simultaneously; handle; with set warp tension ratio, regulate coiling speed, and then change the tension force size; when tension force surpasses certain limit, holding circuit starts and disconnects motor power.The utlity model has simple in structure, safeguard that debugging is convenient, measure accurately, need not the advantage that complicated calculations can be known demonstration.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the partial top view of Fig. 1.
Mark is as follows among the figure: fixedly angle steel 1, pulling force sensor 2, reel 3, band steel 4, movable floor 5, needle roller 6, fixed base plate 7, roll 8, rotational axis hole 9, combined speed reducer 10.
The specific embodiment
The utility model is by drive motors, reductor, reel 3, and movable floor 5, fixed base plate, pulling force sensor 2, deformeter, digital display and computer are formed.
Show among the figure that drive motors and reductor are formed combined speed reducer 10, combined speed reducer 10 is fixedly mounted on the movable floor 5.Reel 3 is directly installed on the output shaft of combined speed reducer 10, and reel 3 position of center line can rotate by the winding reel axle on roll line.Side at movable floor 5 is got rotational axis hole 9, and a side of corresponding fixed base plate 7 is installed rotating shaft, and making movable floor 5 can be that rotate at the center with rotational axis hole 9.Between movable floor 5 and the fixed base plate 7 needle roller 6 is housed, keeps movable floor 5 to rotate flexibly.
The movable floor 5 outer ends angle steel with holes of burn-oning is installed pulling force sensor 2, and pulling force sensor 2 converts pulling force to the signal of telecommunication, finishes the automatic tension monitoring.Pulling force sensor 2 is connected with the fixture on ground, and the ground fixture of the embodiment that shows among the figure is fixing angle steel 1, and pulling force sensor 2 is connected to fixedly on the angle steel 1, and fixedly angle steel 1 is fixed on ground, and an end of connection pulling force sensor 2 is born tension force.Pulling force sensor 2 is also on rolling centerline, and coiling tension is delivered to ground fixedly on the angle steel 1 by pulling force sensor 2, bears whole tension force by pulling force sensor 2 during movable floor 5 work.
The signal output part of pulling force sensor 2 of the present utility model is connected successively with deformeter, digital display, computer, and the signal output part of computer is connected with the control device of drive motors.Deformeter amplifies pulling force sensor 2 measurement results; deliver to digital display through the dividing potential drop scale conversion; directly show the tension force size; simultaneously enter computer and handle, and set warp tension ratio, regulate coiling speed through the A/D conversion; and then change tension force size; when tension force surpasses certain limit, holding circuit starts and disconnects motor power, the unlikely overtension of protection equipment and damaging.
The utility model need not the complicated function computing, thereby amplifies the back dividing potential drop and can utilize digital voltmeter to show tension force numerical value, and computer can be gathered the voltage after strain signal amplifies, and converting in computer obtains tension value.Actual measurement tension force magnitude of voltage and setting warp tension ratio surpass setting voltage and then start protection, cut off all driving motor frequency converter triggering levels, make it stall.Tension signal also can be finished the constant control of coiling tension, makes to batch at tension force to keep keeping under the controlled condition operation.
