Description

Technical Field

[0001] The utility model relates to the technical field related to corrugated paperboard processing, in particular to a bonding device for processing multi-layer corrugated paperboard. Background Art

[0002] Corrugated cardboard is made of at least one layer of corrugated paper and one layer of boxboard paper, and has good elasticity and extensibility. It is mainly used to make cartons, carton sandwiches and other packaging materials for fragile goods. When processing and making multi-layer corrugated cardboard, the cardboards need to be bonded together, so a bonding device for processing multi-layer corrugated cardboard is needed.

[0003] The prior art has the following deficiencies: the prior art "A high-precision corrosion-resistant multi-layer structure corrugated paper processing bonding device" with publication number CN217021630U "includes a device body, a bracket, a lower corrugated paper conveyor belt, a fixed plate and an upper paperboard limiting roller assembly, a bracket is fixed on one side of the bottom of the device body, and the lower corrugated paper conveyor belt is installed on the top of the bracket, a fixed plate is fixed on the inner wall of one side of the device body, and two groups of support seats are installed on the outer wall of one side of the fixed plate, a limited seat is fixed on the outer wall of one side of the support seat, and a connecting arm is movably installed inside the limited seat, a main hydraulic cylinder is movably installed on one side of the top of the support seat, and one end of the main hydraulic cylinder is movably connected to the connecting arm";

[0004] In the above equipment, glue rollers are used to apply glue to the cardboard, but only the surfaces of the upper and lower cardboards are coated with glue, and the two sides of the middle cardboard are not coated with glue, which may easily cause the corrugated cardboard to not be bonded tightly enough, resulting in gaps and delamination. At the same time, dust is easily attached to the surface of the cardboard during transportation, which may affect the subsequent bonding effect if not processed. In addition, when adjusting the height of the lamination roller, multiple sets of connecting rod structures are used, which is relatively complicated and has high inspection and maintenance costs.
