Method.
Background technology
At present in many rubber winding control systems, because rubber production process requires finer, conventional receipts
Volume mode and be primarily present problem have it is as follows：
The detection of angle position instrument rocker and ultrasonic wave coil diameter pattern, as shown in figure 1, label 1 be rubber strip, 2 for re-opening in figure
Power adjusting nut, 3 be rocker, 4 be rolling wheel, 5 be that ultrasound quantity sensor I, 6 is speed changer, due to mounting means and structure
The characteristic of itself, work pivot angle stroke and variable signal slope, and the aequum original of the effect of inertia of machinery swing and counterweight
Cause, such as holding eventually of free roll and film contacts rotation on rocker during work, due to weight select permeability, when linear velocity is too high or
Reverse tension deficiency easily causes rocker floating jump when counterweight kicks the beam, and rolling wheel speed changes shakiness back and forth, when counterweight is overweight
The film of thinner thickness easily produces stretcher strain, and quality problems, therefore active line speed adaption scope ratio occurs in rubber

Analog quantity output, input module are realized, connect up complexity in cabinet outside cabinet, and signal transmission is easily interfered by external disturbance and generation.
Due to being controlled using V/F modes, when coil diameter becomes big, rolling wheel weight is stepped up, and winding wheel increases with coil diameter automatically and rotating speed subtracts
Small (frequency converter frequency reduction).The power torque drop when motor speed reduces, slip become big, afterbody winding when causing the coil diameter to increase
Can not normal work, particularly broad-amplitude film when it is more obvious.
