The analysis of laminating machine laminating common problems

Laminating machine coated plastic film is coated with adhesive, with the substrates for paper printing, after the rubber drum and heating cylinder pressure together, form the unity of paper-plastic products. Through laminating machine coated printing, because the surface is more a thin, transparent layer of plastic film, more smooth shining surface, not only improves the print gloss and color fastness, prolong the service life of the print, plastic film and waterproof, anti-fouling, wear-resisting, folding, resistance to chemical corrosion protection, etc.

Laminating machine

1. Laminating machine does not start: input wires, power cords, voltage is not enough.

2. The temperature measurement is not accurate, thermocouple, temperature controller. Whether the installation is not correct, and damage.

3. Can't work on the vacuum, gas path, hand valve or electromagnetic valve is not closed, vacuum pump motor belt is loose, damage of vacuum gauge.

4. The total power switch trip: heating box input wire leakage, leakage, distribution box outside the wire on the device, electric leakage, etc.

5. Membrane absorption does not reach the designated position: vacuum degree is not enough, leakage, temperature is not enough, the membrane is too thin, posted on other material of workpiece, workpiece concave depth over the lift of membrane, suction time too short, membrane no pushovers, workpiece is too close.

6. Cover the surface of workpiece is folding and can not smooth or Angle: the film is not straight, the film quality is bad, the workpiece polishing is not good, glue spray too much, workpiece under the touch panel is too low.

7. Not to be the membrane absorption down l: electromagnetic valve or valve is on hand.

8. Play break phenomenon: high temperature, heating time is too long, the film quality is bad, no heating.
