Description

Forming process of multi-layer composite plastic rubber bag
Technical Field
The invention relates to the field of plastic bag production, in particular to a multi-layer composite plastic rubber bag forming process.
Background
The plastic bag is made of plastic as main material, is an indispensable article in daily life, is often used for containing other articles, and is widely used because of its advantages of low cost, light weight, large capacity and convenient storage.
When a plurality of bottle-shaped or cup-shaped articles are taken out by a conventional plastic bag, the situation that the bottle-shaped or cup-shaped articles are toppled easily occurs when the plastic bag is carried by hands, even the problem that liquid overflows when the bottle-shaped or cup-shaped articles are toppled occurs when the bottle-shaped or cup-shaped articles are toppled, and the situation that the bottle-shaped or cup-shaped articles collide with each other due to carrying is easy to occur. Meanwhile, due to the fact that glass materials are used for part of bottle-shaped or cup-shaped articles, damage to the articles can cause broken glass fragments to pierce through the plastic bags, so that the risk of scratching exists.
Disclosure of Invention
The invention aims to provide a multi-layer composite plastic rubber bag forming process which is used for producing plastic bags which are favorable for loading and taking a plurality of bottle-shaped or cup-shaped articles and improves the working efficiency.
The invention solves the problems by adopting the following technical scheme:
a multi-layer composite plastic bag forming process comprises the following operation steps: s1, installing and fixing a first film roll and a second film roll on a bag making machine; s2, conveying the first film on the first film roll and the second film on the second film roll; step S3, properly cutting the first film according to the preparation length requirement of the plastic bag; s4, implanting a pull rope on the first film so as to manufacture a film with the pull rope; step S5, performing hot-press sealing on the first film and the second film so as to manufacture continuous connected plastic bags; s6, cutting the positions connected with the plastic bags according to the packaging quantity requirements of the plastic bags; and S7, packaging the cut continuous connected plastic bags.
Wherein, the step S4 includes: s4.1, adjusting the implantation shape of the pull rope by the pushing module, so that the pull rope is implanted on the first film layer; step S4.2, pushing out the stay cord and the solid membrane on the membrane belt to the first membrane layer through the pushing-out module, and bonding the solid membrane on the first membrane layer by the hot-pressing sheet in a hot-pressing manner, so that the stay cord is fixed between the first membrane layer and the solid membrane; s4.3, the first film is guided by the guide plate to be folded in half in the continuous conveying process, and the second film layer is covered on the first film layer and the reinforcing layer; and S4.4, performing hot-press bonding on the second film layer, the first film layer and the reinforcing layer through the first hot-press module, and sealing the pull rope between the second film layer and the first film layer, thereby manufacturing the film with the pull rope.
As a further improvement of the above technical solution, between the step S2 and the step S3, further includes: step S2.1, selecting whether to cut the first film conveyed from the first feeding roller according to the manufacturing requirement of the plastic bag; and S2.2, if operation is needed, the left cutting knife and the right cutting knife are exposed on the guide roller main body through the first driving module, and the distance between the left cutting knife and the right cutting knife reaches the preparation length requirement of the plastic bag through the cutting module.
As a further improvement of the above technical solution, between the step S4.2 and the step S4.3, the method further includes: and S4.2.1, conveying the film strip through a conveying module, and rolling and recovering the film strip separated from the solid film sheet by rotation of a recovery roller.
As a further improvement of the above technical solution, between the step S5 and the step S6, further includes: and S5.1, adjusting the positions of the slitting cutter heads according to the distance between the central lines of the connecting positions of the plastic bags and the positions of the slitting cutter heads until the slitting cutter heads are right opposite to the central lines of the connecting positions of the plastic bags.
As a further improvement of the above technical solution, the step S7 includes: s7.1, conveying the adhesive tape through a pulling and conveying module; s7.2, cutting the adhesive tape through a cutting module; and S7.3, the separated adhesive tape seals the plastic bag roll under the driving of rotation of the plastic bag roll.
Compared with the prior art, the invention has the following advantages and effects:
according to the invention, the operation of implanting the pull ropes on the first film is realized through the implantation module and the first hot-pressing module, and the first film and the second film are used for hot-pressing and sealing to form the plastic bag. Further, through cutting module and first drive module make cutting module can switch between user state and closed state and when the cutting knife is in user state, distance can be adjusted between the cutting knife, does benefit to and carries out suitable cutting to the film in advance according to the manufacturing demand of plastic bag, ensures the production qualification rate of plastic bag, avoids leading to manufacturing cost to increase because the plastic bag of making does not accord with manufacturing standard.
