Closed plate 421, cutter head abutment plate 422 and right abutment plate 423 are in topmost, and cutter 46 is contracted in telescopic chute 450,
When work, topmost thin film 50 and the distribution of about 60 lower film and right-to-left pass through a pair of of drive roll 21, one
To between the first driven voller 23 and a pair of second driven voller 25, and topmost thin film 50 and about 60 lower film abutting；
The spacing between an opposite side hot-pressing roller 39 of upside and an opposite side hot-pressing roller 39 of downside is adjusted first, then
A pair of of drive roll 21 rotates, and drives 25 synchronous rotary of the first driven voller of a pair 23 and a pair of second driven voller, in this way drive upper layer
Film 50 and 60 right-to-left of lower film are mobile, and then an opposite side hot-pressing roller 39 and an opposite side hot-pressing roller 39 of downside lean on
Closely, the rear and front end of such topmost thin film 50 and lower film 60 is sealed by two opposite side hot-pressing rollers 39, then such upper layer
Film 50 and lower film 60 continue to move ahead, and then a pair of of drive roll 21 stops rotating, and topmost thin film 50 and lower film 60 stop
It only moves ahead, hot pressing closed plate 421, cutter head abutment plate 422 and right abutment plate 423 decline, and hot pressing closed plate 421 is to topmost thin film 50
It is sealed with the right end of lower film 60, then cutter 46 stretches out cutting topmost thin film 50 and lower film 60, hot pressing upwards
Closed plate 421, cutter head abutment plate 422 and right abutment plate 423 rise return, and according to above-mentioned principle, a pair of of drive roll 21 is intermittently transported
Row, the 60 interval feeding of topmost thin film 50 and lower film, polybag interval form, and such high production efficiency is not in material
The case where accumulation.
The above content is only better embodiment of the invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
