Simple distinction between A4 paper cutter and slitter rewinder

Many people are not very clear about the difference between the A4 paper cutter and the slitter rewinder, so today I will simply distinguish between the A4 paper cutter and the slitter rewinder for everyone.

  A4 paper cutter is a traditional product, which is used to deal with paper cutting needs in the post-printing period. From a mechanical paper cutter to a tape-controlled paper cutter, it has also developed to a microcomputer program control, color display, full-image operation guided visual processing, and a computer-assisted cutting external programming and editing production data cutting system to enable production preparation Shorter, higher cutting accuracy, lower labor intensity, and safer operation. The operation of the paper cutter is relatively simple and the requirements on the environment are not high. Usually in the general office, the power supply can ensure the power to work. Generally, the paper cutter has an automatic switch system. As long as the paper is lost during the input process, the cutter will automatically rotate to cut the paper. Some cutters need to press the start key once, and the cutter will rotate to continue cutting. After shredding, press the stop reverse key to stop the cutter from turning.

  Slitting and rewinding machine is a special equipment for papermaking. Its purpose is to sequentially rewind the paper rolls (called raw paper rolls) produced by the papermaking machine. After rewinding, the paper is made into finished paper and leaves the factory. At present, the use of AC drive instead of DC drive in the slitter and rewinding machine has become a development trend in the slitter and rewinder industry. The paper roll rolled by the paper roll machine is relatively soft, there may be broken or broken ends, the edges on both sides are not uniform, and the width of the paper web is often not used in paper processing or printing machines. Most paper types (such as newsprint , Letterpress printing paper, packaging paper, etc.) must pass through a slitter and rewind machine to trim, slit, joint, and rewind the paper roll core to form a certain size and a certain tightness of the finished paper roll before leaving the factory. The rewinding process mainly completes three tasks: first, cutting off the raw paper burrs; second, cutting the entire base paper into several widths that meet user specifications; and third, controlling the diameter of the finished paper roll to meet the factory specifications .
