In the present embodiment, the hemming modules 5 are provided in two sets in front and rear in the sheet film 2 conveying direction to hem the upper bag film 21 and the lower bag film 22, respectively.
Preferably, as shown in fig. 10, the folding module 5 is located at the bag opening side and is provided with a guide rod 51 inclined toward the bag bottom.
In the embodiment, the guide rod 51 is located in the conveying plane of the sheet film 2 and is inclined towards the bag bottom direction, during operation, the guide rod 51 presses the upper edge part of the upper bag film 21 or the lower bag film 22, and the edge part is folded towards the bag bottom direction under the action of the inclined structure, and as the sheet film 2 is in a tensioning conveying state on each conveying roller of the tensioning conveying mechanism 1, in the continuous conveying process, the edge part of the upper bag film 21 or the lower bag film 22 which is subjected to inward folding is further folded and compacted, so that the double-layer folded part 50 is formed, the structure is simple, the continuous conveying is not influenced, and the edge folding effect is good.
Further, the angle at which the guide bar 51 is inclined toward the bag bottom direction can be adjusted as necessary, thereby adjusting the width of the folded edge of the side portion of the upper bag film 21 or the lower bag film 22.
Preferably, as shown in fig. 1, the method further includes: the heat-sealing mechanism 6, the flanging module 5 and the heat-sealing mechanism 6 are arranged in sequence along the continuous transmission direction A; the heat-sealing mechanism 6 performs a heat-sealing operation on the folded portion 50, and forms a nip portion 60 that integrally connects the two-layer structure of the folded portion 50, as shown in fig. 11.
Preferably, as shown in fig. 1, the method further includes: the flanging module 5 and the punching module 7 are sequentially arranged in the continuous transmission direction A from front to back; the punching module 7 performs punching work on the folded portion 50, and forms handle holes 701 and bag edge holes 702 that are staggered in the continuous conveying direction a, as shown in fig. 11.
In this embodiment, the hemming module 5, the heat sealing mechanism 6 and the punching module 7 are sequentially distributed along the continuous transmission direction a, after the hemming module 5 hems the bag opening, the punching module 7 punches a handle hole through the hemming part, and the heat sealing mechanism 6 heat seals the pressing part on the hemming parts on the left and right sides of the handle hole, so that the top between the handle hole and the pressing part forms the invisible handle 70, as shown by the thick line in fig. 14, thereby realizing the continuous and efficient production of the invisible handle.
It should be noted that the heat sealing mechanism 6 respectively presses out a pressing portion 60 on the folding portion 50 on both sides of the handle hole 701, and the pressing portion 60 is located between the handle hole 701 and the bag edge hole 702.
Preferably, the punching module 7 and the sealing and cutting mechanism 8 are sequentially arranged in the continuous transmission direction a; as shown in fig. 11, the sealing and cutting mechanism 8 seals and cuts the single bag 20 from the middle of the bag edge hole 702, and the bag edge hole 702 forms the ventilation slits 703 on both sides of the bag opening.
In the present embodiment, in order to cooperate with the heat sealing operation of the heat sealing mechanism 6 and the die cutting operation of the die cutting module 7, the tension conveying mechanism 1 conveys the sheet film 2 intermittently, so that when the conveying is stopped, the sheet film 2 rebounds and relaxes under the action of inertia and the like, which affects the flatness and further the sticking effect. In order to avoid the influence on the previous continuous adhesive conveying process caused by the intermittent conveying, the second laminating roller 322 in this embodiment is always in a rotating state, so that the sheet film 2 can be always kept in a tensioning state, and the linearity and the flatness of the tape adhesion are further ensured.
Working procedure
Step one, a cutting procedure: the cylindrical sheet film 2 is continuously conveyed on the tension conveying mechanism 1, and the upper bag film 21 and the lower bag film 22 on the bag opening side are cut by a cutting mechanism to form a bag opening;
step two, a point breaking process: in the continuous transmission process of the sheet film 2, point breaking lines 40 distributed along the continuous transmission direction A are cut by the point breaking mechanism 4;
step three, edge folding: the upper bag film 21 and the lower bag film 22 on the bag mouth side are each folded by the folding module 5 to form a double-layered folded portion 50, respectively;
step four, a gluing process: the adhesive tape 30 fed from the side part of the tensioning and conveying mechanism 1 is reversed to be in the same direction with the continuous conveying direction A of the film sheet by a reversing mechanism 31 so as to be synchronously conveyed along with the film sheet 2; then, the synchronously transmitted film 2 and the adhesive tape 30 are tensioned and wound on a bonding mechanism 32 for transmission, so that the reversed adhesive tape 30 is pressed and stuck on the inner side surface of the film 2;
step five, a heat sealing process: the heat-sealing mechanism 6 performs heat-sealing work on the folded portion 50, and forms a press-fit portion 60 that integrally connects the two-layer structure of the folded portion 50;
step six, punching and cutting procedure: the punching module 7 performs punching operation on the folding part 50 and forms handle holes 701 and bag edge holes 702 which are distributed along the continuous conveying direction A in a staggered manner;
step seven, sealing and cutting: the sealing and cutting mechanism 8 seals and cuts from the middle position of the bag edge hole 702 to form the single bag 20, and the bag edge hole 702 forms the ventilation cuts 703 at two sides of the bag opening; and then, outputting the single bag finished product.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
