Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb paperboard processing equipment, in particular to a cutting device of a honeycomb paperboard edge wrapping machine. Background Art

[0002] Honeycomb paperboard is composed of a single layer of core paper with a given thickness and a double layer of surface paper glued together. After the honeycomb paperboard is produced and formed, the paperboard needs to be edge-wrapped. The existing edge-wrapping machine places the honeycomb paperboard on a conveyor belt and sends it to a crushing assembly. The crushing wheel of the crushing assembly crushes the honeycomb core along the normal direction of the honeycomb paperboard side, and then performs shaping, gluing and folding to complete the edge-wrapping process. However, directly using the crushing wheel to crush the honeycomb paperboard can easily cause wrinkles in the honeycomb paperboard, so the core paper and surface paper on the side of the paperboard are separated before crushing.

[0003] After searching, the utility model patent with announcement number CN209831753U discloses a cutting device of a honeycomb cardboard edge wrapping machine, including a transmission component and a cutting component. The transmission component includes a bracket, a conveyor belt, a motor, and a first gear. The top surface of the rear end of the bracket is provided with a baffle, and the baffle is used to block one side of the honeycomb cardboard; the bracket is equipped with a driving roller located on the left and a driven roller located on the right, and the conveyor belt is wound around the outer circumference of the driving roller and the driven roller to play a connecting role, and the top surface of the conveyor belt is higher than the top surface of the bracket to prevent the cutting component from touching the bracket when working; the cutting device of the honeycomb cardboard edge wrapping machine is easy to use. Through the arrangement of the transmission component and the cutting component, the cutting blade can cut the side of the honeycomb cardboard to separate the core paper and the surface paper of the honeycomb cardboard, thereby avoiding the problem of wrinkles and deformation of the honeycomb cardboard when the crushing wheel of the edge wrapping machine crushes the side of the honeycomb cardboard.

[0004] However, the above patent has the following shortcomings: it is only convenient for cutting one side of the honeycomb paperboard, which is not practical; it is also difficult to fix the conveyed honeycomb paperboard, which can easily cause the paperboard to shift and tilt during cutting, affecting the cutting quality. To address this problem, we propose a cutting device for a honeycomb paperboard hemming machine. Utility Model Content
