A control system for prolonging the service life of the soft roll surface in the roll nip

Abstract

The invention relates to the technical field of roller pressing area pressurization, and provides a control system for prolonging the service life of a roller surface of a soft roller in a roller pressing area. The control system comprises a data processing unit, a cleaning device control unit, a vibration sensor and a rotating speed sensor, wherein the data processing unit is used for obtaining vibration data collected by the vibration sensor and rotating speed data collected by the rotating speed sensor and conducting preliminary processing. The cleaning device control unit is used for comparing and analyzing the vibration data and the rotating speed data transmitted by the data processing unit to judge the roller surface state of the pressing area soft roller. When it is judged that theroller surface of the pressing area soft roller is abnormal, an online cleaning device is controlled to clean the surface of the pressing area soft roller in real time, so that the service life of the roller surface of the pressing area soft roller is short, and the service life is prolonged. Meanwhile, the roller replacement frequency is reduced, the maintenance workload is reduced, the roller surface treatment cost is saved, and the production time is prolonged.

Description

technical field [0001] The invention relates to the technical field of pressing in a roll nip, in particular to a control system for prolonging the service life of a soft roll surface in a roll nip. Background technique [0002] During the operation of roll equipment such as sizing machines and calenders in the papermaking industry, the abnormality of the roll surface of the soft roll in the roll nip caused by various reasons will lead to large vibration in the nip, and then cause defects such as stun marks / zebra patterns , affecting product quality, especially in the pressurization position of the roller nip such as sizing machine and calender in the papermaking industry. [0003] At present, for the above-mentioned problems that cause defects such as stun marks / zebra patterns and affect product quality, the traditional solution is to change the roll and dismount the machine to treat the roll surface. Maintenance and replacement of pressure rollers can extend equipment mai...
