Abstract:
A roller heating system for a laminating machine, which is adapted to heat and laminate a laminating plastic film of which the inner surface has a fusion gum to cohere to an article desired for lamination, said system comprises a pair of rollers, said pair of rollers include:a first rolling shaft having a first electric heating wire wound around an outer periphery thereof and two first erection holes located on opposing ends thereof, the first electric heating wire having two first ends, each of the two first ends inserted into one of the two first erection holes; a first heat conduction layer covering said first rolling shaft and said first electric heating wire; a second rolling shaft located parallel to said first rolling shaft, the second rolling shaft having a second electric heating wire wound around an outer periphery thereof and two second erection holes located on opposing ends thereof, the second electric heating wire having two second ends, each of the two second ends inserted into one of the two second erection holes; and a second heat conduction layer covering said second rolling shaft and said second electric heating wire; wherein, when said roller heating system for a laminating machine operates, said first rolling shaft and said second rolling shaft rotate in a predetermined direction and said laminating plastic film is then fed therebetween, heating said laminating plastic film respectively through said first heat conduction layer and said second heat conduction layer such that said fusion gum becomes molten and subsequently coheres to said article through the compression of said first and second rolling shafts.
