Introduction Commissioning and maintenance printing operation process

The factors affecting product quality are nothing but human, machine, material, law, and ring. Paper problems and equipment problems are the main aspects of the machine and material factors in the five major factors. Apart from the design and manufacturing processes, printing processes, machine commissioning, and maintenance, these five factors cannot be ignored. Only these issues and problems are satisfactory. Solve the problem, to maximize the effectiveness of the machine and equipment in order to truly achieve harmony between man and nature, to achieve the highest quality printing.

Poorly maintained equipment, such as lack of oil on the shaft bearing, tooth dust accumulated in the dental band, seizure movement blocking teeth, lack of teeth or even dead teeth;

Dentures and pads are worn or concave, and the contact surface is reduced. In addition, the tooth gap between the teeth is filled with paper gray paper, and the friction between the teeth and the pad is small.

The failure of tooth decay and the failure of tooth decay will cause the paper to slip during printing. The open ball will wear out and the cam will wear out. The timing of the transfer will be reduced.

The shaft and drum end bearing wear, the axial clearance increases, roller shaft will produce excessive axial turbulence at high speed rotation;

The raw and auxiliary materials were not properly selected, the ink viscosity was too large, the lining calculation was wrong on the operation process, and the relative sliding amount between the rollers in the printing was large, which all had an adverse effect on the accuracy of the transfer.
