Paperboard cutting machine for paper product production

The invention relates to the field of paperboard cutting machines, in particular to a paperboard cutting machine for paper product production, which comprises a cutting machine body, a groove is formed in the upper end of the cutting machine body, a conveying assembly is fixedly mounted in the groove, and the upper side of the conveying assembly penetrates through the groove. A sliding assembly is arranged on the front side of the upper end of the cutting machine body. When a paperboard is conveyed, the paperboard is placed on the front side of the upper end of the cutting machine body, then the paperboard is pushed, the paperboard can be pushed to the position between the guide roller and the positioning roller through the sliding assembly, then the paperboard can be conveyed through the conveying assembly, and the paperboard is conveyed into the cutting machine body to be cut; by adjusting the rotating speed of the guide rollers or enabling the two groups of guide rollers to rotate in opposite directions, t
