Flat sheet paper cutter is a kind of cutting machine with a wide range of applications. It can be used to cut paper, leather, plastic, cardboard and other materials. The paper cutter is mainly composed of a host (also known as a gantry), a workbench, a paper pushing mechanism, a paper pressing mechanism, a cutting mechanism, etc. The paper pushing mechanism is used to push the paper for positioning and post regulation. The paper pressing mechanism presses the paper in place to ensure that the original positioning accuracy is not destroyed during the cutting process. Side block gauges, the workbench plays a supporting role.
        Printing, packaging, book binding and other production from cutting to printing of finished products and the cutting of the bound book after binding require a paper cutter to cut, so the paper cutter is an important equipment for post-press processing. Flat sheet cutters are widely used in printing plants, bookbinding plants, packaging plants, paper product processing plants, etc.
        Flat sheet cutter cutting process
         1) Position the paper pusher according to the size of the paper being cut
         2) Make the paper that has been collided close to the front surface of the paper pusher and the side fence to perform paper positioning
         3) The paper presser first lowers and presses the paper, then the cutter then falls and cuts the paper
         4) After the cutting is completed, the cutting knife leaves the paper stack and returns, and then the paper presser is raised and reset.
         Factors affecting the safe use of the paper cutter
        The safety of the paper cutter is a problem that many digital printing practitioners tend to overlook, and it affects the safe use of the paper cutter in the following ways:
        1. Braking device. In order to save money, many manufacturers use the principle of circuit braking, that is, cutting off the power supply of the cutter motor through the upper and lower limit sensors. This device may cause "slider" in the event of sudden power failure, loose socket, and sensor failure Extremely dangerous situation. In order to prevent this from happening, it is necessary to use a motor assembly with a mechanical brake device, so that no matter what circuit failure occurs, the motor is locked to avoid accidents.
        2. Double button operation principle. This requires the two buttons to be pressed at the same time, otherwise the cutter motor will not move, which can guarantee the absolute safety of single-person operation.
        3. In the actual use process, two people often cooperate to operate, so that the situation becomes very dangerous, which requires the cutter to be equipped with front and rear safety covers. When the safety cover is opened, the motor will not move to ensure safety.
        4. The above is a safety factor that affects the use process, so pay attention to the replacement of the blade during maintenance and maintenance, use the knife holder to ensure that the blade edge is closed, not only to ensure the safety of people, but also to ensure that the blade is not damaged.

        5. Furthermore, the removed blades must not be left at will to avoid hurting people.
