The technical scheme is as follows: a steel cord meter rice device which characterized in that: the device comprises an alarm, a PLC (programmable logic controller), a PLC touch screen, and a meter counting wheel and a check wheel which are sequentially arranged, wherein the meter counting wheel and the check wheel are respectively and fixedly arranged on respective rotating shafts, meter counting proximity switches and check proximity switches are respectively arranged on the outer sides of the meter counting wheel and the check wheel, meter counting wheel detection blocks used for triggering the meter counting proximity switches are arranged on the meter counting wheel, check wheel detection blocks used for triggering the check proximity switches are arranged on the check wheel, and the meter counting proximity switches, the check proximity switches, the alarm and the PLC touch screen are respectively and electrically connected with the PLC controller; and when the meter reaches a set length every time, the PLC checks the accumulated checking pulse number sent by the checking proximity switch, and controls the alarm to give an alarm when the accumulated checking pulse number exceeds a set range.

It is further characterized in that:

the meter counting wheel and the check wheel are fixedly arranged on respective rotating shafts through bearings respectively.

The meter counting wheel detection blocks are arranged in a two-to-two mode and are symmetrically arranged with the center of the meter counting wheel, and the check wheel detection blocks are arranged in a two-to-two mode and are symmetrically arranged with the center of the check wheel.

The PLC controller comprises a register and a comparator, the register is used for storing the accumulated checking pulse number when the meter reaches the set length every time, and the comparator is used for comparing whether the accumulated checking pulse number is in the set range.

And if the accumulated checking pulse number when the first meter reaches the set length is N, the set range is N +/-one thousandth of N.

The utility model has the advantages that:

the utility model discloses a steel cord meter rice device, meter rice wheel has not only been set up, the check wheel has still been set up, in use, make the steel cord walk around meter rice wheel and check wheel simultaneously under certain tension, meter rice wheel and check wheel meeting are rotatory simultaneously under the effect of steel cord, and then it is rotatory to drive meter rice wheel detection piece and check wheel detection piece, at meter rice proximity switch, check proximity switch's detection under, it gives the PLC controller and counts the operation to send out the pulse constantly, confirm through meter rice wheel count and check wheel count whether accurate, and can send alarm signal when meter rice is suspicious, thereby effectively ensure steel cord meter rice accuracy, ensure that follow-up steel cord curtain cloth calendering goes on smoothly.
