Paper cutting machine

Abstract

The invention discloses a paper cutting machine, and relates to the field of paper cutting machinery. According to the technical scheme, the paper cutting machine is characterized by comprising a machine frame, a paper roll feeding mechanism arranged at one end of the machine frame, a paper cutting mechanism, a paper feeding mechanism and a stacking mechanism, wherein the paper cutting mechanism,the paper feeding mechanism and the stacking mechanism are arranged on the rear side of the paper roll feeding mechanism in sequence. The paper cutting mechanism comprises an upper pressing roller anda lower pressing roller which are rotationally arranged on the machine frame. A cutting knife parallel to the axis of the upper pressing roller is fixedly arranged on the circumferential side wall ofthe upper pressing roller. Nozzles for outward jetting air are arranged on the upper pressing roller and located on the two sides of the cutting knife. A plurality of first air suction holes are arranged in the side wall of the lower pressing roller. According to the paper cutting machine, when paper is cut, the paper and the pressing rollers can be separated, so that a winding phenomenon does not easily occur between the paper and the pressing rollers so as to optimize the production.

Description

technical field [0001] The present invention relates to the field of paper-separating machinery, and more specifically, to a paper-separating machine. Background technique [0002] Paper splitter is also called paper slitter, it is to cut the whole roll or whole raw material into fixed length, such as plastic packaging materials, packaging cartons, steel plates, films, leather, wood chips, etc. Use a paper separator. [0003] Existing paper separators generally include an upper paper roll mechanism, a paper cutting mechanism, and a paper feeding mechanism. First, the entire roll of paper is installed at the upper paper roll mechanism for transmission. Slitting is carried out, and the cut paper is conveyed at the paper feeding mechanism. [0004] The paper cutting mechanism of the existing paper splitter includes two upper and lower pressure rollers, and a cutter is arranged on the upper pressure roller or the lower pressure roller, and the cardboard is cut during the rotat...

AI Technical Summary

Problems solved by technology

[0004] The paper cutting mechanism of the existing paper splitter includes two upper and lower pressure rollers, and a cutter is arranged on the upper pressure roller or the lower pressure roller, and the cardboard is cut during the rotation process. However, this cutting method, When the cutter cuts, the paper is easy to wrap around the pressure roller
