[0002] A paper bag is a bag made of paper, typically used for packaging, carrying, or storing items. It can come in a variety of shapes, sizes, and uses. Paper bags are typically made from paper materials such as kraft paper and cardboard. They are environmentally friendly and recyclable, and have less impact on the environment than some plastic products. Paper bags are widely used in daily life, for example, to carry items when shopping, as gift bags for wrapping presents, and to store documents, stationery, and other items in offices and schools. Some businesses also customize paper bags with their own brand logos and designs for promotional purposes.

[0003] Chinese patent publication number CN210174300U discloses a paper packaging bag edge sealing device, comprising a frame with a conveyor belt mounted on top. One side of the conveyor belt is provided with a gluing device, a flanging device, and a gluing device, sequentially arranged along the conveying direction. The other side of the conveyor belt is provided with a limit device for feeding the packaging paper along the conveying direction. The gluing device comprises a gluing frame, a pressing block, and a pressing roller, each of which is arranged on the gluing frame along the conveying direction. The bottom surface of the pressing block is curved, with the side facing the pressing roller lower than the side facing away from the pressing roller. The lowest point of the pressing roller is lower than the lowest point of the pressing block. Compared to existing technologies, the present invention not only ensures normal conveying of the packaging paper during edge sealing, but also ensures a secure adhesive bond and high-quality edge sealing.

[0004] However, the above-mentioned existing technical solutions have the following defects: they cannot be effectively adjusted quickly according to the needs of paper bags of different specifications. When hot pressing paper bags of different specifications, it is inconvenient to adjust the folding device of the paper bags, resulting in poor use effect of the hot pressing device.

[0005] Therefore, it is necessary to provide a paper bag hot pressing edge sealing device to solve the above problems. Utility Model Content
