High-precision roller-spacing control system

Abstract

The invention relates to an S typed four roller pressing extending line host computer distance adjusting system. A high precision roller distance control system consists of an distance adjusting part and a control part, wherein, the distance adjusting part drives a turbine box by a servo motor through a deceleration box, a worm gear drives a nut through inner and outer gear covers, the screw rod copulated with the nut does not rotate, the rotation of the nut drives the screw rod to move forward or backward in the radial direction, and the screw rod is connected with a bearing body; and the control part is a controller which sends command signals to a servo controller which controls a servo motor, the servo motor feeds back the data information to the servo controller through a coder, the servo controller carries out compare and calculation according to the current roller distance, afterwards the servo controller drives the servo motor to operate or stop, and a closed loop control is accomplished. The accurate fault detection function of the distance adjusting system eliminates mechanical fixed return difference through the procedures so as to ensure the positioning accuracy; the operational synchronization ensures the adjusting stability and synchronization of two ends in the roller canister; the automatic positioning of the roller distance is achieved, and the formula function of the roller distance is achieved.

Description

1. Technical field [0001] The invention relates to rubber calendering equipment, in particular to an S-type four-roller calendering line host distance adjustment system. 2. Background technology [0002] At present, the conventional distance adjustment method used in the rubber industry for the distance adjustment system of the main machine of the S-type four-roller calendering line is 6 double-speed motors. Display the roll gap, and use the displacement sensor to display the crossing amount through the display instrument. Since the sensor is fixed by screws, the long-term vibration may cause the "zero" position of the sensor to be lost; the position of the sensor is easily disturbed by the outside world with a 0-10V DC voltage signal, and the worker can only roughly estimate the roll gap through the instrument, and then After inspecting the product and adjusting the roll gap, qualified products can be obtained through multiple adjustments. Long adjustment time and frequen...

Since the sensor is fixed by screws, the long-term vibration may cause the "zero" position of the sensor to be lost; the position of the sensor is easily disturbed by the outside world with a 0-10V DC voltage signal, and the worker can only roughly estimate the roll gap through the instrument, and then After inspecting the product and adjusting the roll gap, qualified products can only be obtained through multiple adjustments.

Long adjustment time and frequent starting affect the service life of electrical components and motors, and the waste of raw materials is relatively large
