[0022] The two folding parts 602 between the left and right sides of the two side upper parts 601 of the paper bag body 6 to be processed are pre-arranged with folding indentations. After the paper bag body 6 is placed on the electric conveyor belt 13, the electric conveyor belt 13 conveys the paper bag body 6 to between the two longitudinal mechanical clamps 25 according to a pre-set program. Then, the first electric lifter 21 drives the first electric transverse slide rail 22, the first electric longitudinal push rod 23, the second electric lifter 24 and the longitudinal mechanical clamp 25 to move downward according to a pre-set program. At the same time, the first electric transverse slide rail 22 drives the first electric longitudinal push rod 23, the second electric lifter 24 and the longitudinal mechanical clamp 25 to move in the left and right directions. At the same time, the first electric longitudinal push rod 23 drives the second electric lifter 24 to move downward. 24 and the longitudinal mechanical clamp 25 move in the front-to-back direction, so that the two clamping claw parts of the longitudinal mechanical clamp 25, which are initially in the open state, are respectively located on the front and rear sides of the two side upper parts 601 of the paper bag body 6, and then the longitudinal mechanical clamp 25 controls the two clamping claw parts to move closer to each other to squeeze and knead the two side upper parts 601 of the paper bag body 6, so that the two folding parts 602 between the left and right sides of the two side upper parts 601 of the paper bag body 6 are folded according to the folding indentation. At the same time, the second electric lifter 24 drives the longitudinal mechanical clamp 25 to rise upward, so that the longitudinal mechanical clamp 25 drives the two clamping claw parts to squeeze and close the two sealing parts 603 above the two side upper parts 601 of the paper bag body 6. The state of the paper bag body 6 after the folding process is shown in the figure. Fig.11 shown.

[0023] Afterwards, the first electric lift 21 drives the longitudinal mechanical clamp 25 to move upward and away from the paper bag body 6, and then the electric conveyor belt 13 conveys the paper bag body 6 to between the two fixed plate racks 32. At the same time, the multi-track electric lift 31 drives the fixed plate rack 32 to move up and down according to a pre-set program to complete the height adjustment, so that the first guide plate 35 and the second guide plate 36 on the fixed plate rack 32 are aligned with the two sealing parts 603 of the paper bag body 6, and the height of the curved plate structure 3502 near the partition structure 3501 is higher than the sealing part 603 of the paper bag body 6. Then, the electric conveyor belt 13 drives the paper bag body 6 to move upward and downward. The two sealing parts 603 of the paper bag body 6 enter between the two anti-slip belts 34 of the two electric conveyor chains 33 to the left, and the electric conveyor belt 13 cooperates with the two electric conveyor chains 33 to convey the paper bag body 6 to the right. At the same time, the two electric conveyor chains 33 squeeze the two sealing parts 603 of the paper bag body 6 through the two anti-slip belts 34. At this time, the two anti-slip belts 34 extrude a sealing stripe structure on the two sealing parts 603 of the paper bag body 6 through the embossed structure 3401, and the sealing stripe structure can tightly fit the middle areas of the two sealing parts 603 of the paper bag body 6 together.

[0024] After that, the electric conveyor belt 13 cooperates with the two electric conveyor chains 33 to continue to convey the paper bag body 6 to the right, so that the upper areas of the two sealing parts 603 of the paper bag body 6 enter the front and rear guide channels between the first guide plate 35 and the second guide plate 36 respectively, and the two sealing parts 603 of the paper bag body 6 are captured. After the two sealing parts 603 of the paper bag body 6 completely leave the two guide channels between the first guide plate 35 and the second guide plate 36, they will move to the left to the narrowing area of ​​the second guide plate 36 toward the first guide plate 35, so that the upper areas of the two sealing parts 603 of the paper bag body 6 The two sealing parts 603 of the paper bag body 6 are also tightly fitted together, and then the two sealing parts 603 of the paper bag body 6 will continue to move to the left and pass through the curved plate structure 3502 of the first guide plate 35. The two sealing parts 603 of the paper bag body 6 that are tightly fitted together will contact the inclined structure of the curved plate structure 3502. As the two sealing parts 603 of the paper bag body 6 continue to move to the left along the inclined structure of the curved plate structure 3502 of the first guide plate 35, the two sealing parts 603 of the paper bag body 6 will gradually bend backward and downward along the arc-shaped curved surface in the inclined structure of the curved plate structure 3502 of the first guide plate 35, thereby completing the sealing process of the paper bag body 6.

[0025] Finally, the electric conveyor belt 13 cooperates with the two electric conveyor chains 33 to continue conveying the paper bag body 6 to the right, so that the portion of the sealing portion 603 of the paper bag body 6 that is bent backward and downward is aligned with the slot structure 3601 of the second guide plate 36. At the same time, the electric unwinding shaft 42 releases the label bottom strip 7 covered with label stickers 71 outward, and the label bottom strip 7 passes through the three first conveying rollers 43, the two second conveying rollers 44, the outer surface of the electric slide bar 45 and the two third conveying rollers 46, and is wound onto the electric winding shaft 47. When the label bottom strip 7 passes through the triangular pointed cone structure of the electric slide bar 45, as shown in FIG. Fig.10 As shown, the label sticker 71 on the label bottom strip 7 will not be bent at a large angle along the triangular pointed cone structure of the electric slide bar 45, so that the front end of the label sticker 71 will be separated from the label bottom strip 7, and the adhesive layer on the left side of the front end of the label sticker 71 will face the slot structure 3601 of the second guide plate 36. At this time, the front end of the label sticker 71 will be adhered to the part of the sealing part 603 of the paper bag body 6 that is bent backward and downward through the adhesive layer, and then the electric slide bar 45 drives the label bottom strip 7 to move to the left, so that the remaining part of the label sticker 71 is separated from the label bottom strip 7 and is completely attached through the adhesive layer. The label sticker 71 is fully pasted on the portion of the sealing portion 603 of the paper bag body 6 that is bent backward and downward, so as to automatically complete the labeling process of the paper bag body 6, and the label sticker 71 is pasted between the portion of the sealing portion 603 of the paper bag body 6 that is bent backward and downward and the upper side portion 601 on the rear side of the paper bag body 6, so that the bent sealing portion 603 of the paper bag body 6 is firmly fixed on the upper side portion 601 through the label sticker 71, thereby improving the laminating stability of the sealing portion 603 of the paper bag body 6. After that, the electric conveyor belt 13 drives the paper bag body 6 to the lower left along the unloading slide plate 14 for unloading.

[0026] Example 2 On the basis of Example 1, Figure 1-Figure 10 As shown, a second electric transverse slide rail 26 is installed between the lifting components of the two first electric transverse slide rails 22 of this embodiment; a second electric longitudinal push rod 27 is installed on the sliding component of the second electric transverse slide rail 26; and a transverse mechanical clamp 28 is installed on the telescopic component of the second electric longitudinal push rod 27.

[0027] In the step of clamping the two upper side parts 601 of the paper bag body 6 by the longitudinal mechanical clamp 25, the second electric transverse slide rail 26 drives the second electric longitudinal push rod 27 and the transverse mechanical clamp 28 to move in the left and right directions. At the same time, the second electric longitudinal push rod 27 drives the transverse mechanical clamp 28 to push forward, so that the two clamping claws of the transverse mechanical clamp 28, which are initially in the open state, are respectively located on the left and right sides of the two folding parts 602 of the paper bag body 6. Then, the transverse mechanical clamp 28 controls the two clamping claws to move closer to each other, so that the two clamping claws of the transverse mechanical clamp 28 push the paper bag body 6 respectively. The two folding parts 602 of the bag body 6 are moved towards each other, and the longitudinal mechanical clamp 25 is used to clamp the two upper side parts 601 of the paper bag body 6, so that the two folding parts 602 of the paper bag body 6 are folded along the folding indentations. In this process, under the push of the clamping claw part of the transverse mechanical clamp 28, the two folding parts 602 of the paper bag body 6 can be folded more smoothly according to the folding indentations, so that the two folding parts 602 of the paper bag body 6 are folded more neatly, thereby further improving the stability of the sealing quality of the paper bag body 6.

[0028] Example 3 On the basis of Example 1, Figure 1-Figure 10 As shown, two third electric longitudinal push rods 51 which are symmetrical to each other are installed on the fixed frame of the electric conveyor belt 13 of this embodiment, and the third electric longitudinal push rods 51 are located on the right side of the multi-track electric elevator 31; the telescopic ends of the two third electric longitudinal push rods 51 are each fixedly connected with a clamping block 52.

[0029] After the electric conveyor belt 13 transfers the folded paper bag body 6 to between the two clamping blocks 52, the two third electric longitudinal push rods 51 push the two clamping blocks 52 toward each other, so that the two clamping blocks 52 jointly push the paper bag body 6 to move along the front-rear direction of the electric conveyor belt 13, so that the two sealing parts 603 of the paper bag body 6 are respectively aligned with the two guide channels between the first guide plate 35 and the second guide plate 36, thereby improving the success rate of the two sealing parts 603 of the paper bag body 6 entering the two guide channels between the first guide plate 35 and the second guide plate 36, thereby improving the production efficiency of the paper bag body 6.
