Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, in particular to a gluing device for corrugated paper production. Background Art

[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. During gluing, glue needs to be added between paper layers through a gluing device. In the existing corrugated paper gluing device, after gluing, the glue on the cardboard will be adhered to other equipment, which not only leads to a waste of glue and affects the bonding effect between paper sheets, but also may cause other devices to fail to operate normally.

[0003] For example, a Chinese utility model patent with announcement number CN214637748U discloses a high-efficiency gluing device for corrugated paperboard production. Although this solution does not require manual holding of paperboard for moving and gluing during gluing, and is more efficient, the gluing roller of this solution glues the paperboard from the bottom. When the glued paperboard comes down from the gluing device assembly line and flows to the conveyor belt of the next process flow, the paperboard and glue at this time will stick to the conveyor belt, resulting in a waste of glue. Based on this, a gluing device for corrugated paperboard production is proposed. Utility Model Content

A second servo motor 17 connected to one end of the direction-changing roller 4 is fixedly connected to the upper side of the base 1, and the second servo motor 17 drives the direction-changing roller 4 in an intermittent manner. A corrugated paper gluing mechanism for gluing the corrugated paperboard is provided on one side of the direction-changing roller 4, and a paperboard unloading mechanism for transporting the glued corrugated paper to the next process flow is provided on the other side of the direction-changing roller 4.

[0022] The corrugated paper gluing mechanism includes a glue box 14 fixedly connected to the upper side of the base 1, a glue roller 15 is rotatably connected to the inner side of the glue box 14, and the side of the glue roller 15 is covered with knurling 8 of special shape. The knurling 8 is in a rhombus shape or a honeycomb shape and has a certain groove depth, so that a certain amount of glue can be contained. A notch 16 is provided on the upper side of the glue box 14, and a No. 1 servo motor 13 connected to one end of the glue roller 15 is fixedly connected to one side of the glue box 14. A glue liquid adding port 7 is connected to one side of the glue box 14. A cardboard feeding mechanism for conveying the cardboard to be glued to the glue box 14 is provided on one side of the notch 16, a cardboard positioning mechanism for positioning the cardboard is provided on the upper side of the notch 16, and a pressure roller positioning mechanism for cooperating with the glue roller 15 to press and glue the cardboard from above is provided above the notch 16.

[0024] The cardboard positioning mechanism includes a No. 2 transition chute 10 that cooperates with one end of the feeding conveyor belt 11 and is fixedly connected to one side of the slot 16.
