In this embodiment, as shown in fig. 2, the folding device 2 performs the folding of the outer side of the pouch semi-finished product S3 inward, and the folding device 4 performs the folding of the inner side of the pouch semi-finished product S3 outward.

As shown in fig. 1, the last folding device, in this embodiment, a two-folding device 4, has a roller 41 at the downstream end of the two-folding device 4. The first exhaust process B comprises the roller 41 of the two-folding device 4 and the first exhaust device 5 correspondingly arranged with the roller 41, the roller 41 and the first exhaust device 5 are located at the terminal K1 area position in the last folding device, in this embodiment, the K1 position of the first exhaust device 5 is located above the roller 41, and the first exhaust device 5 is correspondingly compressed with the roller 41 area of the two-folding device 4, so as to realize the first exhaust of the packet semi-finished product S3.

As shown in fig. 5, the conveyor belt 56 has a multi-layer structure, and includes a sponge layer 563, a base layer 561, and a conducting bar 562, wherein the sponge layer 563 is disposed on the periphery of the base layer 561, the conducting bar 562 is disposed on the inner side of the base layer 561, and the conducting bar 562 is matched with the first groove 541 and the second groove 551, so as to ensure that the conducting bar 562 can be smoothly embedded into the first groove 541 and the second groove 551. The base layer 561 ensures strength and wear resistance of the conveyor belt 56, and the guide strip 562 guides the conveyance of the conveyor belt 56 to prevent deviation thereof. The sponge layer 563 is compressed with the rigid device of the two-fold device 4, and the air in the packet semi-finished product S3 is extruded and discharged by utilizing the high elastic characteristic of the sponge that recovers elasticity after being compressed.

The driving pulley 57 is connected to an external driving source (a motor), not shown, and under the driving action, the driving pulley 57 drives the driving roller 54 on the first driving shaft 51 to rotate, so that the driving roller 55 is also driven to rotate by the conveying belt 56 mounted on the outer periphery of the first driving roller 54, and the annular conveying of the conveying belt 56 is realized to perform the first air exhaust on the small package semi-finished product S3.

The adjustment portion 58 can be set by extending or retracting the piston rod of the first air cylinder 583, so as to drive the first driving roller 54 and the driven roller 55 to link the contact and separation of the conveyor belt 56 and the area of the roller 41 of the two-folding device 4. When the conveyor belt 56 is in contact with the area of the rollers 41 of the two-folding device 4, a first evacuation of the packet semi-finished product S3 is achieved; when the conveyor belt 56 needs to be maintained in a shutdown state, the conveyor belt 56 is far away from the roller 41 area of the two-folding device 4.

When the first exhaustion is completed, the pouch semi-finished product S3 continues to travel to the downstream side along the main flow path L1, as shown in fig. 1. At this time, the tape processing step C on the sub flow path L2 is also in operation. Specifically, the continuously drawn tape material S4 conveyed on the sub flow path L2 enters the tape processing step C. The adhesive tape processing procedure C comprises a feeding device 6 and a cutter device 7, wherein the feeding device 6 is provided with an adsorption structure of a vacuum box, is communicated with the vacuum box through an externally connected air suction device (fan) and is used for adsorbing and conveying the continuously pulled adhesive tape material S4 to the cutter device 7. The cutter device 7 includes a cutter 71 and a base roller 72, the cutter 71 has a blade, the base roller 72 has a base blade (not shown), and the base roller 72 has a vacuum absorption structure therein, so that the continuously drawn adhesive tape material S4 is cut into adhesive tape pieces S5 when the blade of the cutter 71 abuts against the base blade of the base roller 72. The tape tabs S5 are then adsorbed to the outer circumference of the bottom roller 72 by the negative pressure inside the bottom roller 72 and transferred onto the main flow path L1.

After the adhesive tape compounding process D is completed, the pouch semi-finished product S3 enters a second air discharging process E, as shown in fig. 1, where the second air discharging process E includes a second air discharging device 10 and a conveying device 9, which are oppositely disposed. The second exhaust device 10 has the same structure as the first exhaust device 5 of the conveyor belt type, and the conveying device 9 has an adsorption structure of a vacuum box, and adsorbs the packet semi-finished product S3 on the belt for conveying through the negative pressure effect inside the vacuum box. The second air discharge means 10 is pressed against the conveyor 9, and the air in the packet semi-finished product S3 is discharged by the high elasticity of the sponge layer conveyor belt, and the air is gradually discharged because the second air discharge means 10 has a certain length.

The second exhaust process E realizes second exhaust of the small-package semi-finished product S3, ensures that air which is not exhausted by the first exhaust can be exhausted smoothly, ensures 100% exhaust, and ensures that good conditions are provided for the quality and yield of small-package products and the integral packaging of the rear end. Since the conveying device 9 is engaged with the downstream-side packet heat-sealing device 11, since the packet heat-sealing device 11 is a relatively precise device and requires frequent maintenance, an adjustable structure is provided at a position of the conveying device 9 close to the packet heat-sealing device 11, as shown in fig. 6. But also can be arranged into a fixed structure, and the fixed structure can be selected according to the actual situation.

After the two air discharge processes, the pouch semi-finished product S3 enters a pouch heat-sealing process F, as shown in fig. 1, where the pouch heat-sealing process F includes a pouch heat-sealing device 11, and the pouch heat-sealing device 11 performs heat-sealing of the pouch semi-finished product S3 at the location of the pouch material S1 between the adjacent formed products in an air-discharged state, to form a heat-sealing area S6, as shown in fig. 2. In order to enhance the aesthetic appearance of the product, the heat-sealing area S6 has a certain pattern, and the pattern can be set according to the requirement. The complete exhaust of the small bag is realized by setting two exhaust processes, and the heat sealing effect and the binding force of the small bag finished product are effectively ensured.

A packet cutting process G including a packet cutting device 12 as shown in fig. 1 is provided on the downstream side of the packet heat-sealing process F, and the packet cutting process G performs cutting of the heat-sealed packet semi-finished product S3 at an intermediate position of the heat-sealing zone S6 to form individual packet products S, thereby completing the entire packaging process.
