Remote vibration monitoring system and method for eccentric main shaft of sponge cutting machine

Abstract

The invention provides a remote vibration monitoring system and method for an eccentric main shaft of a sponge cutting machine. The remote vibration monitoring system for the eccentric main shaft of the sponge cutting machine is characterized by comprising a vibration sensor, a key phase sensor, a data acquisition card, and an upper computer, wherein the vibration sensor and the key phase sensor are arranged on the sponge cutting machine and are respectively connected with the data acquisition card, and the data acquisition card is connected with the upper computer. The vibration information of the sponge cutting machine is effectively collected, and the working condition of the sponge cutting machine can be effectively monitored in a datamation mode. Furthermore, on one hand, remote real-time monitoring and data storage are realized; and on the other hand, by effectively utilizing the vibration information, the damping effect can be achieved by calculating the unbalance amount.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a remote vibration monitoring system and method for an eccentric spindle of a sponge cutting machine. Background technique [0002] The cutter cutting mechanism of the sponge cutting machine converts the high-speed rotational motion of the motor into an up and down linear motion, thereby realizing the function of cutting the sponge. The mechanism is an eccentric slider crank mechanism. When the machine starts to work, the motor rotates at high speed, which drives the eccentric wheel to perform high-speed rotary motion. During the cutting process, due to the rapid return characteristic of the crank slider mechanism, the speed and acceleration of the slider change suddenly. Inertia impact is caused, and the vibration is very serious; the rotary motion of the eccentric wheel will also cause a certain vibration to the mechanism, which reduces the cutting spee...

AI Technical Summary

Problems solved by technology

The mechanism is an eccentric slider crank mechanism. When the machine starts to work, the motor rotates at high speed, which drives the eccentric wheel to perform high-speed rotary motion. During the cutting process, due to the rapid return characteristic of the crank slider mechanism, the speed and acceleration of the slider change suddenly. Inertial impact and severe vibration are caused; the rotary motion of the eccentric wheel will also cause certain vibration to the mechanism, which reduces the cutting speed and accuracy

In order to solve this problem, there are a large number of detection platforms on the market that can effectively reduce the vibration of the sponge cutting machine, but there are still the following deficiencies: 1) the lack of remote detection of the platform, 2) the insufficient ability of the platform to store and process large amounts of data
