自动套袋机
The sealing mechanism of the automatic bagging machine uses a lower insert plate to push the rope, an upper insert plate to tighten the tongue, and a suction nozzle to adsorb and push the double-sided adhesive for pasting. This solves the positioning interference and rope clamping problems of bags with ropes in mechanical packaging, achieving tight sealing and stable transportation.

AI Technical Summary
Existing technologies cannot solve the problems of positioning interference, sealing rope clamping, and long-term packaging loosening of tote bags with drawstrings in mechanical packaging while controlling packaging costs, especially in vertical packaging methods where sealing rope clamping and product loosening are serious problems.
The sealing mechanism of the automatic bagging machine uses a lower insert plate to push the strap, an upper insert plate to tighten the tongue, a suction nozzle to absorb and push the tongue to the double-sided adhesive, and a pressing plate to press it firmly, ensuring that the strap and tongue are separated and a tight seal is achieved.
It effectively prevents the straps from extending and getting caught during the sealing process, ensuring a tight and aesthetically pleasing seal, preventing product loosening, reducing packaging costs, and improving transportation stability.

Abstract
Claims
1. An automatic bagging machine, comprising a sealing mechanism (4), characterized in that: The sealing mechanism (4) includes: The lower insert plate (404) is set to move up and down, and is used to push the material with the rope at the opening of the packaging bag (9) downward and to act as a backing for the suction nozzle (403) to suck up the tongue (91) of the packaging bag (9). The upper insert plate (402) is located outside the lower insert plate (404). The upper insert plate (402) is movable up and down and is used to push and pull the tongue (91) of the folded packaging bag (9) upward before it is sucked by the suction nozzle (403). The suction nozzle (403) is located above the upper insert plate (402). The suction nozzle (403) is set to move back and forth. It is used to suck up the tongue (91) of the folded-up packaging bag (9) from the outside and push it to the double-sided tape at the opening of the packaging bag (9) for double-sided tape to stick. The bag pressing plate (8) is set to move up and down and is used to press and compact the packaging bag (9) when sealing.
2. The automatic bagger according to claim 1, characterized in that: The sealing mechanism (4) further includes a sealing frame (401), an upper moving seat (405), a lower moving seat (406), and a first guide (407). The first guide (407) is disposed on both sides of the sealing frame (401). The upper moving seat (405) and the lower moving seat (406) are vertically and vertically disposed on the sealing frame (401) through the first guide (407).
3. The automatic bagger according to claim 2, characterized in that: The sealing mechanism (4) further includes a first driving member (408) and a second driving member (409). The first driving member (408) and the second driving member (409) are both disposed on the sealing frame (401) and drive the upper moving seat (405) and the lower moving seat (406) to rise and fall on the first guide member (407) respectively. The upper insert plate (402) is disposed on the lower moving seat (406).
4. The automatic bagger of claim 2, wherein: The sealing mechanism (4) further includes a sealing plate (410) and a second guide (411), wherein the sealing plate (410) is disposed on the upper moving seat (405) via the second guide (411).
5. The automatic bagger according to claim 4, characterized in that: The sealing mechanism (4) further includes a third driving member (412), which is disposed on the upper moving seat (405) and drives the sealing plate (410) to move. The suction nozzle (403) is disposed on the sealing plate (410).
6. The automatic bagger of claim 2, wherein: The sealing mechanism (4) further includes a third guide (421) and an upper moving seat (422). The third guide (421) is disposed on the sealing frame (401), and the upper moving seat (422) is disposed on the third guide (421) in a horizontally movable manner.
7. The automatic bagger according to claim 6, characterized in that: The sealing mechanism (4) further includes a fourth driving member (423), which is disposed on the upper moving seat (422). The lower insert plate (404) is connected to the fourth driving member (423), and the fourth driving member (423) drives the lower insert plate (404) to rise and fall.
8. The automatic bagger of claim 1, wherein: The number of the suction nozzles (403) is at least two, and the axes of the at least two suction nozzles (403) form an angle of 20° to 30° with the upper surface of the packaging bag (9).
9. The automatic bagger of claim 1, wherein: The suction nozzle (403) includes: A sleeve (413) is disposed on the suction nozzle (403); The straw (414) is slidably disposed inside the sleeve (413), and the rear end of the straw (414) is provided with a limiting block (415), and the front end of the straw (414) is provided with a suction cup (416). A front locking block (417) is disposed at the front end of the straw (414); The elastic element (418) is sleeved on the straw (414) and located between the front locking block (417) and the sleeve (413).
