Description
Technical field
The present invention relates to plastic packaging bag production field, and in particular to a kind of production technology of plastic packaging bag.
Background technology
Plastic packaging bag is a kind of using plastics as raw material, for the packaging bag of various articles for use in production and living, is used extensively
In daily life and industrial production.Conventional plastic packaging bag is mostly that polyethylene film is made, and the film is nontoxic, therefore can be used for
Contain food.It really includes inner membrance, aluminium foil and die three-layer plastic film to plastic packaging bag, and plastic packaging bag is producing
When, it is necessary to which inner membrance, aluminium foil and die are combined into a tunic after be fabricated to packaging bag again.
Existing plastic packaging bag in compound tense, be all first by die and aluminium foil be combined with each other in after one layer of plastic foil again
Plastic packaging film is compounded to form with inner membrance, need to pass through repeatedly transmission in the above-mentioned plastic foil of compound tense.But existing technique is present
Following problem:The thickness of die is 1.2, and the thickness of aluminium foil is 0.65, and the thickness of inner membrance be 5 and more than, formerly will
Die and aluminium foil be combined with each other then again with inner membrance compound tense, in transmit process because the thickness of die and aluminium foil compared with
It is thin, cause plastic foil to receive larger tensile force and be deformed.
The content of the invention
It is an object of the invention to provide a kind of production technology of plastic packaging bag, the technique can avoid plastic packaging bag
It is deformed in production process.
To reach above-mentioned purpose, base case of the invention is as follows:A kind of production technology of plastic packaging bag, use are compound
Device is compound to plastic packaging bag progress, and wherein set composite includes frame, let off roll, wind-up roll, transfer structure, extruding knot
Structure, drying structure, driving structure and gluing structure, the let off roll and wind-up roll are rotationally connected with frame both ends respectively, described
Let off roll and driven respectively by driving structure with wind-up roll, the gluing structure, extrusion structure, transfer structure and drying structure according to
It is secondary to be fixed in frame, in addition to link, described link one end be rotatably connected in frame, the link other end turns
Dynamic to be connected with compression roller, the compression roller offsets with wind-up roll;
Its production stage includes:(1)Aluminium foil and inner membrance are separately fixed on let off roll aluminium foil and inner membrance are subjected to compound, formation
Plastic sheeting;
(2)By step(1)In plastic sheeting and die realized by plastics set composite it is compound;
Wherein:The winding tension of wind-up roll is 140-160N, and the unwinding tension of aluminium foil let off roll is 70-90N, inner membrance let off roll
Unwinding tension is 95-110N;Humidity is 55-65%.
During using this offshoot program, inner membrance and aluminium foil, which are separately fixed at, to be realized on let off roll and unreels, it is compound after plastic sheeting
Winding is wound on wind-up roll.In compound tense, after unreeling, aluminium foil or inner membrance have contacted with adhesive structure for aluminium foil and inner membrance
Into viscose glue, then by extrusion structure, aluminium foil and inner membrance are pressed together.Transfer structure plays transmission effect.Stick together
Plastic foil afterwards completes the drying to glue after drying mechanism, realizes and compound finally winds on wind-up roll.In winding,
