According to the present invention, referring to fig. 6 and 7, a cross-drawing plastic bag is manufactured, in which the plastic bag 9 is structured by three-sided heat sealing, and a heat-pressure seal 94 is provided at a bag tail 92; the plastic bag 9 is also provided with an 8-shaped through hole 95 for lifting; the stacking structure adopts a plurality of plastic bags (9) with bag heads 91 and bag tails 92 folded in half to be overlapped in a crossed manner, in the embodiment, the plastic bags 9 are stacked up and down, and the bag heads 91 are positioned in a folding gap between the bag heads 91 and the bag tails 92 of the plastic bags 9 above the bag heads 91; the bag tail 92 is in the folding gap between the bag head 91 and the bag tail 92 of the plastic bag 9 below the bag tail 92.
The side edges 94 of the same side of all the overlapped plastic bags 9 are in the same vertical plane, i.e. the side edges 94 of all the plastic bags 9 are in a flush state. In fig. 6, the mark a is a heat-seal land.
When the plastic bag 9 is extracted, one end of the bag head 91 of the plastic bag 9 is grasped, the plastic bag 9 is upwards extracted, the plastic bag 9 upwards moves, the bag tail 92 upwards moves and can generate acting force for the bag head 91 of another plastic bag 9 covering the bag tail 92, so that the bag head 91 of the plastic bag 9 covered by the bag head 91 upwards moves for a certain distance, and further the bag head 91 of the next plastic bag 9 is driven to upwards move after the plastic bag 9 is extracted by a user, the next extraction is convenient, and any connecting part does not exist between the plastic bags, and the plastic bag is completely cut off, so that the plastic bag 9 is very labor-saving and quick to extract. It should be understood that the gap at the cross-fold of the plastic bag 9 and the width of the heat-seal land are exaggeratedly shown for convenience of observation and understanding, and in practice the width of the heat-seal land of the side 93 is about 0.5 to 1 mm.
According to the present invention, there is provided an apparatus for continuously manufacturing such cross-take plastic bags, which is manufactured by the following steps with reference to fig. 1 and 5: two groups of continuous film 10 base materials are prepared and respectively arranged on two rollers 1, and are continuously fed through a plurality of feeding rollers 11 synchronously driven by a driving device such as a motor, the plurality of synchronously driven feeding rollers 11 can stably and continuously feed the continuous film 10, and the continuous film 10 is ensured to keep a tight stretching state in the feeding process without damaging the continuous film 10. A material pressing guide roller 1b is arranged at the discharging position of the roller 1 to ensure that the continuous film 10 is kept flat during discharging.
The continuous film 10 firstly moves to the swing arm speed adjusting device 2, and the moving stroke of the continuous film 10 is adjusted by changing the angle of the swing arm 2a of the swing arm speed adjusting device 2, so that the feeding speed is adjusted. If the feeding speed is too high, the swing arm 2a can be driven to rotate clockwise, the travel stroke is increased, and the effect of slowing down the feeding speed is achieved, and vice versa. Wherein the swing arm 2a is driven by a servo motor 2 b.
Referring to fig. 2, the continuous film 10 is fed to the die cutting device 12 and the rubber roller 4, where the outer contour of the die cutting device 13 is fit with the outer contour of the rubber roller 4, and the continuous film 10 is conveyed to the fit; the die cutting device 13 punches the continuous film 10 to form a 8-shaped through hole 95. The spacing of the punches arranged on the outer contour of the die-cutting device 13 depends on the diameter of the die-cutting device 13 and the head-to-tail spacing of the plastic bags 9 to be produced.
After the perforation is completed, the continuous film 10 is fed to the seal adjusting device 5; the seal adjusting device 5 is provided with a photoelectric sensor which can identify the 8-shaped through hole 95 on the continuous film 10.

The seal adjusting device 5 is provided with a movable guide roller 5a capable of adjusting the running path of the continuous film 10. If one 8-shaped through hole 95 of the continuous film 10 passes through the photo sensor and is recognized, and the corresponding 8-shaped through hole 95 of the other continuous film 10 passes through the photo sensor and is recognized after the time t, the system will calculate the position difference of the corresponding 8-shaped through hole 95 of the two continuous films 10 according to the time t and the feeding speed of the continuous film 10. Then, the system increases or decreases the stroke of the continuous film 10 by driving the movable guide roller 5a to move according to the calculated position difference, thereby achieving the purpose of adjusting the traveling path of the continuous film 10. The positions of the 8-shaped through holes 95 of the two groups of continuous films 10 are adjusted to be consistent, so that when the two groups of continuous films 10 are fed to the main driving wheel device 7 for pressing, the 8-shaped through holes 95 of the two groups of continuous films 10 can be completely overlapped, and the processing precision is ensured.

The distance between the heat-sealing blocks 3a arranged on the outer contour of the heat-sealing roller 3 depends on the diameter of the heat-sealing roller 3 and the head-to-tail distance between the production plastic bags 9; and the ratio of the diameter of the heat-sealing roller 3 to the diameter of the rubber roller 4 is 1:2, so as to ensure that the continuous film 10 can be stably attached to the outer contour of the rubber roller 4, and further, the hot pressing can be smoothly carried out.
After the hot pressing is completed, the continuous films 10 are fed to the sealing adjusting device 5, and the positions of the hot-pressing sealing openings 94 of the two groups of continuous films 10 are adjusted to be consistent, so that when the two groups of continuous films 10 are fed to the main driving wheel device 7 for pressing, the hot-pressing sealing openings 94 of the two groups of continuous films 10 can be completely overlapped, and the processing precision is ensured.
Referring to fig. 3 and 4, the continuous film 10 is fed to the main driving wheel 7a of the main driving device 7, and the continuous film 10 is pressed tightly on the main driving wheel 7a by the pressing wheel 6, so that the continuous film 10 is prevented from position deviation during pressing and the yield of finished products is not affected. Meanwhile, the outer contour of the main driving wheel 7a is provided with a vacuum hole 7c, and the vacuum hole 7c can adsorb the continuous film 10, so that the stability of the continuous film 10 on the main driving wheel 7a is further ensured.
The outer contour of the main driving wheel 7a is also provided with a symmetrical cutter 7b and a groove 7d matched with the cutter 7 a; at the joint of the two main driving wheels 7, the cutter 7b of one main driving wheel 7 is embedded in the groove 7d of the other main driving wheel 7. The cutter 7b heats the side edge of the continuous film 10 and the hot-pressing seal 94 to 210-250 ℃; when the two groups of continuous films 10 are pressed by the two main driving wheels 7a, the heated positions of the two groups of continuous films 10 are bonded into a whole, namely the two side edges of the continuous films 10 and the heat-pressing seal 94; the pressed continuous film 10 is discharged from the lower part of the joint of the two main driving wheels 7a, and the cutter 7b cuts the plastic bag 9 from the tail end of the hot-pressing seal 94. In fig. 4, reference B denotes a cutter edge portion, and reference C denotes a cutter heating portion.
When the plastic bags 9 are discharged, the bag pressing device 8 arranged below the main driving wheel device 7 is used for pressing and stacking; the bag pressing device is composed of two metal plates 8a, and the two metal plates 8a are symmetrically arranged relative to the joint of the driving wheel device 7; the two metal plates 8a alternately swing up and down in turn to press down the plastic bags 9 discharged from the main driving wheel 7a in sequence.
The two metal plates 8a are symmetrically arranged relative to the vertical plane on which the plastic bag 9 is discharged, and are alternately pressed down, so that the plastic bags 9 can be stacked end to end. After a certain number of plastic bags 9 are stacked, they are transported by the conveyor belt 13 to the next station for packing.
