1. Ensure that the voltage, current and hydraulic equivalents are correct and stable before starting up.

2. Before the equipment is ready for operation, all personnel must notify the departure device to ensure personal safety before starting the operation.

3. When running, do not touch the running film roll or roll core with your hands to avoid personal injury caused by hand getting involved.

4. During the operation, avoid scratching or cutting each roller core with a knife or hard object.

First package: Before the equipment is put into operation, check whether the working positions are properly adjusted. The parts to be lubricated should be filled in advance. Check if the tool is sharp.

After all the normal work, you can run the car first, check whether there is any abnormality, and input the order to be processed into the computer list check in advance; after the equipment is put into work, the equipment should be adjusted according to the production situation. The state ensures that the slitting machine has a moderate indentation, no burr slitting, and the trimming position on both sides is appropriate. Ensure that the cross-cutting machine has smooth paper feeding and accurate cutting length. For vertical and horizontal cutting machines that are connected to production management, it is also necessary to monitor the operation of the machine at the same time, to prevent paper jamming and defective products;

After that, clean the dust and paper scraps on the equipment in time, check the grinding wheel and remove the water from the oil and the water in the gas storage tank, and check whether there is any abnormality in the running part. Then, according to the instructions, cut off the power supply and maintain the computer operating system.

  1. The signals that can be used for mechanical condition monitoring and fault diagnosis are vibration diagnosis, oil sample analysis, temperature monitoring and non-destructive testing. Other technologies or methods are supplemented. situation.

       2, slitting and rewinder in the analysis and processing of vibration signals, in addition to classical statistical analysis, time-frequency domain analysis, time series model analysis, parameter identification, recently Frequency refinement techniques, cepstrum analysis, resonance demodulation analysis, three-dimensional holographic spectrum analysis, axial trajectory analysis, and short-time Fourier transform, Winger distribution and wavelet transform based on non-stationary signal assumptions have been developed.

       3, slitter rewinder embedded technology and the development of emerging virtual instrument technology, fault diagnosis devices and instruments have been developed through the initial analog monitoring instrument Computer-based real-time online monitoring one with fault diagnosis system and microcomputer-based portable monitoring and analysis system.
