GFJ-720 Thermal Laminating Machine
1, general introduction
TYPE LAMINATOR is the new products of our factory developed in accordance with. our nation’s conditions after importing the advanced technology from a abroad .
The machines are advanced in design, compact in construction and convenient and convenient to use, it is mainly used to compounding automatically single or double sides of printed matter by BOPP-smeared thick film, After compounding, the printed matter is smooth in appearance, bright in color and strong in intensity. It is also anti-water and damp-resi stance So, it is widely used in the covening of book and mounting of picture, wall chart , map and wrapping paper. Besides, it can also and manufacturing system in modem printing industry.

3.Construchion and working tenet
This machine is consisted of machine stand, transmission mechanism, front and -1-
back glue roller package, pressure adjusting mechanism, electric system etc. When single-side coating paper , the working tenet is that: smeared film and the coated paper will be heated to a certain degree in front pressure roller package 3 and 4.Due to heat pressure, the smeared film’s glue face will melt and stick to the paper, and will be passed out after pressed film’s by back pressure roller package 10 and 11, then it is rolled by receiving and rolling shaft 18.
When double-sides coating paper ,the working tenet is the same, If the coated matter is PVC film, the tenet is the same as paper coating.
4. Operation method
4.1 Check the spare parts of the machine before first use it, The machine shall be place evenly.
4.2 Connecting to the power source, the machine shall be connected to the ground in good condition.
4.3 When single coating, place the smeared film the central part of the film feeding shaft 7. When double-sides coating, place the smeared film on the film feeding shaft 7 and 20,see picture1. Connecting the machine to the power source, when the red light is on, there is instruction on temperature controller, Adjusting the temperature controller’s switch to the needed coating temper ature (gener ally at appr.70-90 degree) . About 20 minutes later, the temperature raised to the needed degree, then push the button, adjust speed button, the motor will rotate for a while, then the coating begins, If double-sides coating, no need to heat the back roller.
4.4 Adjusting front and back pressure roller hand wheel 2 and 5 to make the pressure of front and back pressure roller package even.
4.5 When single-side coating, pass the smeared film (glue-smeared face down)and paper (face up) through front pressure roller package, while double-sides coating, place the paper between two pieces of smeared films, The coated products will be passed out through back pressure roller. When double-side coating, open both the up and down temperature controllers to heat the front and back pressure rollers.
4.6 When coating PVC film, the method is the same as single-side coating paper.But before coating, use adjusting hand wheel 2 to open pressure to open pressure roller package’s up and down rollers, keep a certain chstanee between the two rollers, When the film passes, it will only pass through pressure roller package for beat press.
5.1 If operating the machine normally, add little lubricating oil in thain-wheel and bearing once half a month.
5.2 If the machine does’t work for a long time, use front and back glue roller pressure adjusting hand wheel 2 and 5 to open the up and down glue rollers to prevent them form being pressed and out of shape.
5.3 Keep glue rollers clean, If they are dirty, brush it by waterless alcohol or caetone.
5.4 Normal fault and methods
Fault Cause Method
Machine can’t start Fuse melts or electric power and voltage abnormal Exchange check whether electric power and voltage is normal
Temperature rise too slowly or can’t rise Electrothermal pipe damaged temperature controller out of control Exchange of repair
Wrinkles on face of product Improper abjusting of front and back pressure rollers Adjust pressure roller to make the pressure even
Fog of white spot on face of product Temperature too low Raise temperature
Sticking between film and paper is not strong Pressure of pressure roller not enough Adjust press
Difference between measured and designed temperature is too large Temperature measuring couple not pressed on rolling pipe Adjust setup position to make it pressed on the face of rolling pipe
Temperature out of control Double-side control silicon damaged Exchange
1. Every time before operation, please connect it to the ground to keep it in good ground-connecting condition.
2. User shall not increase the capacity of electric system’s fuse, our factory shall not be responsible for any quality accident resulted from such act. Do not use copper wire instead of fuse.
