Description

technical field [0001] The invention relates to the technical field of tension control-related experimental devices, in particular to an embedded tension controller. Background technique [0002] Tension controllers are used to control the tension of long strip materials, and are widely used in lithium battery pole piece manufacturing, paper making and other industries. The existing tension controller is controlled by a programmable logic controller (PLC), which is expensive and requires professionals to operate and maintain. Therefore, it is necessary to invent a tension controller with safety, good development, remote control, easy operation and maintenance, and good man-machine interface. [0003] The Chinese patent with the application number 201220189685.5 discloses an embedded tension controller. The controller uses Omron PLC as the core, calculates the rotation angular velocity of the cloth roll through the rotational speed signal of the unwinding mechanism fed back ...

AI Technical Summary

Problems solved by technology

The structure is more complex and the cost is higher

The control system judges the motor speed according to the proximity switch, so as to determine the size of the winding diameter, but the resolution is low, and the gear is used for long-term use, which will cause gear wear and reduce the accuracy.

[0005] The tension controller mentioned in "Realization of ARM-Based Multifunctional Tension Controller" is based on the STM32F103ZET6 chip as the core, and has a modular design with high cost. However, the man-machine device in this system is an LED display screen, which cannot be realized. Real human-computer interaction; and this system does not study the direction of remote control
