When carry-over pinch rolls 17 rest, 2 roll bodies controlled by high material swing arm are swung to feedstock direction, will be molded the side that carry-over pinch rolls 7 are inputted
Material continuous film 29 is deposited in material stock component, when cutting 17 feeding of carry-over pinch rolls, and 2 roll bodies controlled by high material swing arm are to charging
Opposite direction is swung, and the side layer continuous film 29 being deposited in material stock component is exported, such side layer continuous film 29 is in mechanism
Certain tension force can be remained；As preferred, the roll body of material stock component is provided with the rib roller of fin 13 for surface, beneficial to side
Expect that continuous film 29 is further shaped, prevent flange from tilting；
Side layer continuous film 29 passes through the input roller 14 that turns back, the first folding in the component that turns back after the output of material stock component
Return roller 15 and second turn back roller 16 formation one L-shaped inflection transport path, preferably Open Side Down for L-shaped inflection transport path, this
Then sample can again turn back and is connected with the mechanism of main pipeline by L-shaped inflection transport path laterally across main pipeline
And cooperation, the space on top is made full use of, land area is reduced；It is preferred that, input module, steering assembly and flange component are set
Put in the side of main pipeline, and material stock component, inflection component and follow-up cutting part and main pipeline are integrated；
L-shaped inflection transport path further integrated blanching can press component 21 or supersonic welding connected components, by side layer continuous film 29
Flange further fix, its flange is prevented, while being also beneficial to following process；
Side layer continuous film 29 is after the output of inflection component, and cutting carry-over pinch rolls 17 discharge end is provided with cutting knife 18, opposite side
Material continuous film 29 carries out fixed length cutting to form side layer, and the cutting carry-over pinch rolls 17 are to be provided with to roller, and to roller surface
The annular vent groove 19 being coaxial therewith；The steel wire rope smoothing device 20 of anti-detent plug material is provided with the air discharge duct, due to side layer two
Turn on one's side Qi Hou centers splicing, so some gases can be retained in side layer continuous film 29, cutting carry-over pinch rolls 17 be to roller,
When coordinating extruding transmission, internal gas needs to exclude, and otherwise the damage of film body can be caused to also bring along transport resistance, in cutting
The surface of carry-over pinch rolls 17 sets the gas retained in the offside rim charge continuous film 29 of annular vent groove 19 to be discharged；For prevent film body with
The adhesion of carry-over pinch rolls 17 is cut, or is filled in annular vent groove 19, steel wire rope smoothing device 20, institute are set on cutting carry-over pinch rolls 17
It is parallel with discharging direction to set in a row to state steel wire smoothing device, and every steel wire is corresponding with an annular vent groove 19, and every
Steel wire insertion is arranged in the annular vent groove 19 of the cutting discharging opening of carry-over pinch rolls 17, and so no matter film body is with cutting carry-over pinch rolls 17
（To roller）Any one roll body stick together, can be dredged by steel wire rope, exclude adhesion；
