[0002] A paper bag is a bag made of paper and has various uses and characteristics. A paper bag is usually made by processing paper materials, and common materials include kraft paper, white cardboard, etc. Its structure is relatively simple and generally consists of a main body part and a sealing part formed by folding or pasting. In daily life, paper bags are widely used. When shopping, merchants often use paper bags to package goods. It is environmentally friendly and beautiful, which can enhance the overall image of the goods; when giving gifts, delicate paper bags can increase the mystery and sense of ceremony of the gifts; in schools and offices, paper bags can be used to store documents, books, stationery and other items. The designs of paper bags are also diverse. Some paper bags are printed with attractive patterns, brand logos or promotional information on the surface, playing the role of advertising and promotion; some focus on simplicity and practicality to meet the needs of different consumers. From an environmental protection perspective, paper bags are easier to degrade than plastic bags and have less impact on the environment.

[0003] The bottom sealing device of a paper bag mainly consists of the following parts: a bottom sealing mechanism: This is the core part of paper bag bottom sealing and usually includes a bottom sealing roller, a glue coating device, etc. The bottom sealing roller evenly coats the glue on the bottom of the paper bag, and then bonds the bottom of the paper bag to the side through pressure to complete the bottom sealing operation. A paper bag limiting mechanism: It is used to fix the position of the paper bag to prevent the paper bag from moving or floating during the bottom sealing process. Common paper bag limiting mechanisms include clips, suction cups, etc. A cooling component: It cools the paper bag after bottom sealing, accelerates the solidification of the glue, and improves the bottom sealing quality. The cooling component can be a fan, a cooling channel, etc. A positioning component: It ensures that the paper bag maintains the correct position and posture during the bottom sealing process for accurate bottom sealing operation. The positioning component can be a sensor, a guiding device, etc. A control system: It is responsible for coordinating the work of each part of the bottom sealing device, including controlling the coating amount of the glue, the pressure of the bottom sealing roller, the working time of the cooling component, etc., to ensure the bottom sealing quality and efficiency.
