Glazing machine skills and quality of what needs
1) Skill requirements of glazing machine
The operation of the machine should be stable, the transmission system should be normal, no abnormal noise; The operating mechanism is flexible and reliable, and the operation of the actuator is harmonious and correct, without jamming and spontaneous movement; Smooth system oil road dredging; The glazing coating layer should be smooth, there should be no wrinkles, damage, marks, drums, bubbles and significant streaks, the glazing layer does not stick bad appearance; The difference in gloss of the printed coating layer is not greater than the value of the rules in the table above; The operating noise of active glazing machine shall not be more than 85dB (A), and the operating noise of semi-active glazing machine shall not be more than 80dB (A); Safety protection equipment should be completely reliable, and exhaust gas equipment.
2) Quality requirements of the upper optical and mechanical gas
The insulation resistance between the short-circuited power circuit and the maintenance circuit (including the machine base) wire shall not be less than 1mω; The resistance value between the conductor terminal and any exposed conductor part of the electrical equipment and the body shell shall not be greater than 0.1ω. It is necessary for the electrical equipment to undergo a 1min voltage test. The test voltage is 1500V, and there should be no breakdown or flashover appearance.
3) the experimental method of glazing machine
For the empty operation experiment of the machine, it is necessary to carry out the empty operation experiment of ≥120min for each commodity of the polishing host, during which the high-speed operation should be ≥15min.
4) Operating temperature test of the bearing of the glazing machine
After the empty operation experiment, the operating temperature of the bearing is measured with a point temperature meter, which should be less than or equal to 35℃;
The primary shaft of the glazing machine, the parallelism between rollers and the radial circular runout test of the operation surface;
After the empty operation of the machine, the parallel degree between the main axes and rollers in the gladiator, such as measuring, coating, embossing (lining roller), and the radial circular runout of the primary axis and the working surface of the roller shall be measured with the feeler ruler and dial gauge respectively. The measured values shall conform to the corresponding rules in the table above.
5) Noise test of glazing machine
When the polishing machine is operating at the highest speed, the noise of the machine is measured with an ordinary sound level meter. The microphone is 1.5m above the ground and 1m between the middle and the outside of the machine. Four points are measured, and the arithmetic mean value should be: the noise of active polishing machine should not be more than 85dB (A); Operation noise of semi-active glazing machine shall not be more than 80dB (A).
