1. Moveable blade device.
2. Guiding roller in oven will synchronously rotates with main shaft.
3. Solenoid operated valve controlling is adopted for Anilx roller and drawing roller.
4. Automatic meter-measuring devices.
5. Key mode air shaft is used for unwinding and rewinding shafts, easy to load and unload.
In the coating process, the coating gap is poor and the pole piece wrinkles are analyzed:
3. The front and back are not aligned
(1) Operational aspect: the first side gap is consistent. The operating parameters are not adjusted well. The light eye is blocked. The unwinding pinch roller forgets the clip.
(2) Equipment: The tension behind the second side is large. The front tension is small.
4 When the middle is turned on, the white space becomes smaller, and the back 3-4 pieces are inaccurate.
Equipment: The tension is not allowed at the beginning of the start. The first side has no memory function. The foil strip slides forward 2-3mm when starting. The tension starts first when starting. The back roller does not turn. The coating head has no pinch roller or is not clamped.
5. The last piece is in a parallel trailing tail
Operation: coating the back roller spacing (the first side is tailed, the second side is not trailing); the back roller is pulled slowly when the machine is stopped 6. The head thickness is thin or the head is thin and thick. Operation: The head and tail parameters are not adjusted well 7 There is no effect on the action
(1) Material: The foil is tight on both sides
(2) Equipment: the foil tension is small and the moment leaves the back roller.
8. Double-sided large piece of whitening phenomenon: the light eye is not sensed. The first side gap is abnormal. The light eye is covered.
(2) PET transfer film
The transfer film is also called a heat transfer film. The transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage, smooth surface and good peelability, and can be used repeatedly. It is mainly used as a vacuum aluminum plating carrier. After the PET film is placed in a vacuum aluminum plating machine, the rubber film is combined with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the paperboard by the adhesive action. A so-called aluminized cardboard is formed. The production process of aluminized cardboard is:
PET base film→release layer→color layer→aluminized layer→glue layer→transfer to cardboard.
Vacuum aluminum-plated cardboard is a kind of high-grade novel packaging material developed with metal-gloss cardboard. This kind of aluminum-plated cardboard has bright color, strong metallic feeling, bright and elegant printing, and can replace the large-area bronzing of printed matter, which has played a icing on the cake for the beautification of goods. Because it adopts the vacuum aluminum plating method, the surface of the cardboard is covered with only a thin layer of 0.25um~0.3um thin and bright and bright, only one-fifth of the aluminum foil layer of the aluminum foil, so that it It has a noble and beautiful metallic texture, and has environmentally friendly properties that are degradable and recyclable. It is a green packaging material. Through the formulation and process adjustment, Jiangsu Zhongda was successfully developed in 2005 and put into the market in large quantities, receiving good economic benefits.
