Pneumatic metering device for cable

Abstract

The invention relates to a metering device of cables and discloses a pneumatic metering device used for cables. The device comprises a bracket, an upper clamping roller, and a lower supporting roller and a coder which are arranged on the bracket. The device is characterized in that a pneumatic slide valve and a corresponding gas control valve are arranged on the bracket, an upper clamping roller axis is fixed on the piston rod of the pneumatic slide valve, an upper clamping roller bearing is connected with the upper clamping roller axis, an upper clamping roller body is fixed on the upper clamping roller bearing, an upper supporting roller body is over against a lower supporting roller body up and down, and the gas control valve controls the piston rod of the gas control valve to move linearly up and down.

Description

technical field [0001] The invention relates to a cable meter counting device, in particular to a pneumatic meter counting device for cables. technical background [0002] The meter meter device for cables is a special device for effectively controlling the length of cables. The early meter counting device used a mechanical counter, and the progress of the cable drove the meter wheel to rotate, thereby driving the mechanical counter to count. Due to the mechanical error of the mechanical counter itself, and the mechanical wear caused by long-term use, there is a certain error in the accuracy, and the longer the use time, the lower the accuracy. With the widespread use of electronic counters in the industry, mechanical counters are gradually being replaced by electronic counters. At present, electronic meter counting devices are widely used, but no matter whether mechanical or electronic meter counting is used, there is a fatal problem, that is, The cable slips during the m...

Problems solved by technology

Due to the mechanical error of the mechanical counter itself, coupled with the mechanical wear caused by long-term use, there is a certain error in the accuracy, and the longer the use time, the lower the accuracy.

With the widespread use of electronic counters in the industry, mechanical counters are gradually being replaced by electronic counters. At present, electronic meter counting devices are widely used, but no matter whether mechanical or electronic meter counting is used, there is a fatal problem, that is, The cable slips during the meter counting process. With the long-term use of the compression spring, it will gradually fail and the cable core will not be pressed tightly, so the meter counting accuracy will be greatly reduced, causing a very large damage to the next process or the sub-disk. trouble
