Description

Paper cutting device with adjustable cutting length Technical Field The invention relates to the technical field of paper cutting production, in particular to a paper cutting device with an adjustable cutting length. Background The paper cutting device is used for cutting longer finished paper into required sizes, and in the prior art, as disclosed in Chinese patent publication No. CN118083676B, a paper extraction folding machine for paper extraction production is provided, wherein the paper cutting device is matched with bottom blades arranged on a first bottom knife roller and a second bottom knife roller through an upper blade so as to complete paper cutting operation. But the cutting length of the paper cannot be adjusted in the device, so that the device is difficult to be suitable for the production of paper with different specifications, and is not beneficial to the on-demand switching of the product production line. Disclosure of Invention The invention aims to solve the defect that the cutting length of paper cannot be adjusted in the prior art, and provides a paper cutting device with adjustable cutting length. In order to achieve the above purpose, the present invention adopts the following technical scheme: The design is cut length adjustable paper and is cut device, including equipment frame, still include: the length-adjustable cutting assembly comprises a cutting roller and a negative pressure adsorption roller, the cutting roller and the negative pressure adsorption roller are rotatably mounted in the equipment frame, the cutting roller and the negative pressure adsorption roller are driven to rotate through a group of driving motors respectively, the cutting roller is provided with a first cutting knife, the negative pressure adsorption roller is used for dragging paper materials, and the first cutting knife can cut off the paper materials on the negative pressure adsorption roller. Preferably, the first cutting knife is provided with a plurality of groups around the circumference of the cutting roller. Preferably, a first slot is formed in the outer surface of the cutting roller, a knife rest is fixedly mounted in the first slot through a screw, and a first cutting knife is mounted in a clamping manner on the knife rest. Preferably, the upper side and the lower side of the tool rest are also abutted with a plurality of groups of fastening bolts, and the fastening bolts can be connected with the inner wall threads of the first slot. Preferably, the outer surface of the negative pressure adsorption roller is provided with a second slot, a second cutting knife is mounted in the second slot in a clamping manner, and the first cutting knife can be matched with the second cutting knife.
