Large package lifting control system outside the machine

Abstract

The invention relates to a machine large package lifting control system comprising a coiling roller with a central motor, two friction rollers with rotating motors, a lifting mechanism used for lifting the coiling roller, a PID controller used for controlling the lifting mechanism, pressure sensors used for monitoring the pressure of the coiling roller and friction rollers and a PCC controller connected to the PID controller and the pressure sensors in a signal manner. The PCC controller presets the textile thickness and primary pressure, after the coiling roller completes the coiling for a first circle, the lifting mechanism adopts the set textile thickness as the lifting amount to lift the coiling roller, the PCC controller compares the pressure of the pressure sensors with a preset pressure value, and the PID controller controls the lifting amount of the coiling roller for the sequential circle through the lifting mechanism. The coiling roller can be lifted continuously by increasing the pressure between the coiling roller and the friction rollers in the coiling process, the pressure valves of the coiling roller and friction rollers can be maintained, and the textile is prevented from corrugating and deforming.

Description

technical field [0001] The invention relates to the technical field of textile machinery control, in particular to a control system for lifting large packages outside the machine. Background technique [0002] The traditional large package on the market adopts the combined winding mode of winding roller and friction roller in structure. During the winding process, as the diameter of the winding increases, the winding roller rises passively, causing the weight of the fabric to always be fully compressed. On the friction roller, when the self-weight of the fabric reaches a certain weight, the cloth surface will be wrinkled and deformed, which increases the load on the friction roller and the winding roller. Contents of the invention [0003] The purpose of the present invention is to provide an external large package lifting control system that prevents the wrinkling and deformation of the fabric surface during winding. [0004] The technical scheme that realizes the object...
