Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper bag production equipment, in particular to a kraft paper bag gluing device. Background Art

[0002] As an environmentally friendly packaging product, kraft paper bags are easy to recycle and degrade after use, can effectively protect the environment, and have been widely chosen and used by people. They have good development needs and market prospects. In the production process of kraft paper bags, due to the different needs of products, some kraft paper bags often need to be glued inside to make them waterproof and moisture-proof. Usually, the gluing process of kraft paper bags usually requires the use of a gluing device to gluing the kraft paper bags.

[0003] At present, the existing Chinese patent announcement CN221437379U discloses a gluing mechanism for kraft paper bags, including a conveyor line, side panels are fixedly provided on both sides of the conveyor line, support frames are provided on the top of the side panels, cross beams are welded between the support frames on both sides, a material blocking assembly is installed on the cross beam, a mounting plate is welded on the top of the support frame, and a cylinder is fixedly provided on the outer wall of the top of the mounting plate, and a lifting platform located below the mounting plate is installed on the output end of the cylinder, a through hole is opened on the outer wall on one side of the top of the lifting platform, and a guide rod is slidably inserted into the inside of the through hole, and an adjusting nut is threaded on the external surface of the top of the guide rod.

[0004] Although the device can guide the kraft paper bags above the conveyor line through the material blocking component, ensuring that the kraft paper bags can be accurately conveyed under the glue injection head, and the gluing operation can be achieved at the same position on each kraft paper bag, and at the same time, the cylinder drives the lifting platform to descend twice, thereby blocking the kraft paper bags while completing the gluing operation on the kraft paper bags, the following defects still exist: during the production, transportation and storage of kraft paper bags, due to the influence of various factors, wrinkles and uneven parts are easily formed on their surfaces. These uneven surfaces will directly affect the uniform coating of glue during the gluing process, thereby affecting the bonding effect. The device does not have a component for leveling the kraft paper bags, and has certain limitations when used. Utility Model Content
