Description

TECHNICAL FIELD

[0002] Cable metering device is used to calculate the length of cable, mainly used for the fixed-length and fixed-quantity winding of cable. At present, the common cable metering device on the market generally includes a metering wheel and a pressure roller. When in use, the cable passes between the metering wheel and the pressure roller. During this process, the cable is pressed against the metering wheel by the pressure roller. When the cable moves, it will drive the metering wheel to rotate, thereby calculating the moving length of the cable by the encoder installed on the metering wheel. For example, the cable machine rotary metering device disclosed in the Chinese patent document with publication number CN220288575U realizes the metering function by using the above structure. This device can adjust the distance between the pressure roller and the metering wheel according to actual production needs, thereby adjusting the interaction force between the wire and the metering wheel, avoiding the problem of inaccurate metering caused by cable slipping on the metering wheel, and improving the metering accuracy. At the same time, it can be compatible with cables of different diameters, with high compatibility. However, when the distance between the pressure roller and the metering wheel is adjusted to the right position, the pressure roller cannot move according to the change in the local wire diameter of the cable. As a result, a sudden change in wire diameter can easily cause the pressure roller to slip and fail to press the cable against the metering wheel. A sudden increase in wire diameter can easily cause the cable to be transmitted poorly. Both of the above situations can lead to a decrease in metering accuracy. SUMMARY
