Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production and processing, in particular to a cross-cutting machine for preventing warping in paper production. Background Technique

[0002] Cardboard is a plate-shaped material used to make cartons, paper bags, notebooks, business cards, embossed paintings and other materials. Its common colors are light brown or light gray, and some are very white. It is a plate-shaped material processed from wood pulp fibers and recycled fibers. In the production process of cardboard, cutting is required for convenient subsequent use, so a pipe cross-cutting machine is needed.

[0003] After retrieval, the patent publication number CN210121973U discloses a cross-cutting machine for corrugated cardboard production. Aiming at the problems of low automation degree of the existing cross-cutting machine, which requires a large amount of labor and cannot cut a large number of corrugated cardboard of the same length, the following scheme is proposed. It includes a workbench, and two vertical plates and two support columns are fixed on the top of the workbench. Both vertical plates are located between the two support columns. A plurality of conveyor rollers are arranged between the two vertical plates. A conveyor belt is sleeved outside the conveyor rollers. A plurality of placing plates are fixedly arranged at equal intervals on the conveyor belt. A top plate is fixed between the tops of the two support columns. A baffle is fixed to the bottom of the top plate. A servo motor is installed at the bottom right end of the baffle. The utility model has novel design, ingenious structure and simple operation. It can drive the corrugated cardboard to move automatically, can cut a large number of corrugated cardboard of the same length, has high automation degree, and saves time and effort.

[0004] However, this patent still has deficiencies. It does not have a structure for limiting and pressing the cardboard. During the conveying process, the cardboard is prone to shift, resulting in unqualified quality of the cut cardboard and causing waste. Moreover, during the cutting process, since there is no pressing structure on both sides of the cutting blade, the cutting blade is prone to cause the cardboard to warp when it falls and cuts, affecting the production quality.

[0005] Therefore, we propose a cross-cutting machine for preventing warping in paper production. Content of the Utility Model
