The arrangement of each equipment in the longitudinal direction is followed by a plastic woven tube bag unwinding device 1, C color printing film unwinding device 21, and a composite pressing roller device 3. , D color printing film unwinding device 22, color printing film plastic woven bag winding device 6, during production, the preparation work is to place the plastic woven tube bag roll on the plastic woven tube bag unwinding device 1, and carry out manual traction, The plastic woven tube bag enters the center of the two composite rollers of the composite press roller device 3 through a number of guide rollers along the process, and then enters the color printing film plastic woven bag winding device 6 through a number of guide rollers for standby. The other preparation is to print the C color film The color printing film and D color printing film are respectively drawn from the color printing film unwinding device to the front and back of the composite pressing roller device 3. At this time, the plastic extrusion double die 4 is ready for feeding and heating. Various preparations are in place, and the composite double The die head is advanced to the working position above the two composite rollers of the composite pressing roller device 3. At this time, there are C pattern color printing film, C casting film, plastic woven tube bag, D casting film and D pattern in sequence above the composite pressing roller device 3. Color printing film, because the C salivation film has a certain viscosity and temperature, one side of the C pattern color printing film and the plastic woven tube bag can be firmly glued together, and the D salivation film is used to make the D pattern color printing film and plastic woven on the other side. The tube bag is firmly stuck together. Because the C pattern color printing film and the D pattern color printing film are printed by the gravure printing machine separately, and they are unrolled separately when they are compounded, the alignment of the C pattern color printing film and the D pattern color printing film has become a problem. It can only be compared manually online, and there are many waste products.
