Assembly structure of internal circuit of plate type roller

Abstract

An assembling structure of an internal circuit of a plate-shaped roller comprises a plate-shaped roller mandrel, a mandrel rotating supporting assembly, a signal collecting and transmitting inner module and a signal collecting and transmitting outer module, the plate-shaped roller mandrel is rotationally connected with the mandrel rotating supporting assembly, and the signal collecting and transmitting inner module is fixedly arranged in an inner module mounting hole of the plate-shaped roller mandrel; the signal acquisition and transmission outer module is fixedly arranged on the outer side face of the mandrel rotating supporting assembly, is coaxially arranged with the signal acquisition and transmission inner module and is fixed, and the signal acquisition and transmission inner module and the signal acquisition and transmission outer module are of a full-shielding structure relative to the outside; when the signal acquisition and transmission outer module works, power is transmitted to the signal acquisition and transmission inner module through electromagnetic coupling, so that the problems of spark and short service life of the collector ring are solved; and information is transmitted between the signal acquisition and transmission inner module and the acquisition and transmission outer module through infrared communication, so that the reliability and the stability of data transmission of the plate type roller in a complex electromagnetic environment are ensured.

Description

technical field [0001] The invention relates to the technical field of rolling processing equipment for non-ferrous metal plates, strips, and foils, and specifically relates to an assembly structure of an internal circuit of a plate-shaped roll. Background technique [0002] During the rolling process of non-ferrous metal plates, strips and foils, the quality of the plate shape needs to be tested, so the shape roller is an indispensable testing equipment in the rolling process of non-ferrous metal plates, strips and foils; The shape measurement of electrical sensors is one of the mainstream technologies of contact shape rolls at present. It has the characteristics of high measurement accuracy and strong overload capacity, so it has been widely used in the field of metal strip and metal foil rolling in recent years; piezoelectric sensors It is installed in the high-speed rotating plate-shaped roller. It is a charge-type sensor. The charge signal generated during the working p...

Problems solved by technology

[0003] In addition, how to provide reliable power supply to the large number of charge amplifiers installed in the high-speed rotating plate-shaped roller is another technical problem that needs to be solved; the traditional power supply between two mutually rotating moving parts is carried out through slip rings , but there is high-speed sliding friction in the collector ring, so it is easy to generate sparks and radiate electromagnetic interference, which seriously affects the stability and reliability of the charge amplifier and its subsequent data acquisition circuit, resulting in the collected data Distortion occurs, which leads to the failure of the plate-shaped roller to work normally; at the same time, because the collector ring works in a high-speed sliding friction state for a long time, the service life of the collector ring is short, and frequent maintenance and replacement are required, which not only affects the utilization rate of the rolling mill equipment , while increasing the maintenance cost of the plate roll
