Paper cutters in the field of office printing can be divided into manual type, electric type, hydraulic type, etc., regardless of the brand type. It is recommended that office printing companies choose the paper cutter that suits them from three aspects:
        1. Security
        The paper cutter is different from other mechanical products and belongs to the four-level risk machine tool with the highest risk level. When selecting a cutter product, it is important to investigate its safety and reliability. Such as whether the paper cutter presser has a fall prevention device; whether the moving parts can be equipped with a full-blocking safety cover to avoid accidental breakage of parts and components and personal injury; whether the cutter has infrared electronic control system and electronic safety Knife lock etc. to indicate the safe range.
        2. Mechanical structure
        The earliest mechanical paper cutters used spring pressure for pressing paper and a slider structure for pushing paper. The structure is relatively simple and the commissioning and maintenance are also relatively simple, but the pressure of the paper is low and the cutting accuracy is poor, which cannot meet the high degree of printing The request for cutting precision cannot meet the requirements of medium and high-end packaging and printing products. In the 1950s and 1960s, there was a double-rail paper cutter without a groove on the working platform. Later, it was gradually replaced by the dovetail groove structure of German Bora. At present, some domestic machinery manufacturers also produce double-rail paper cutters, but their overall structure and performance are not as advanced and applicable as the paper cutters of Pola. The paper cutter with double guide rail structure is very troublesome to adjust the accuracy, and the price of changing the guide rail after wear is more expensive, but the operation accuracy of this equipment is high. The precision adjustment of the paper cutter with the dovetail slot structure is simple and convenient. Only the plug iron needs to be replaced after wear, but the accuracy is slightly lower. When choosing a paper cutter, the printing company should choose a dual-rail paper cutter or a dovetail slot cutter according to its own needs and the actual conditions of the products to be processed.
        3. Work efficiency and cutting accuracy

        The working efficiency and cutting accuracy of the paper cutter is an aspect that printing companies think more about when purchasing paper cutters. In this regard, the computer-controlled paper cutter is much better than ordinary paper cutters. The paper pusher of the ordinary paper cutter is controlled by the fine adjustment of the buttons and the hand wheel during the operation of traveling and retreating. The operator has a large labor intensity and low work efficiency. The microcomputer program-controlled paper cutter is programmed to optimize the cutting process and improve work efficiency. While pursuing work efficiency, users also demand the fastest cutting speed to cut out products with higher dimensional accuracy. Therefore, the most advanced paper cutters currently in domestic consumption have adopted the most advanced ball screws and linear guides in the world. Its characteristics are smooth transmission, high positioning accuracy, small cumulative error, no need to adjust the movement gap for long-term work, and eliminates the impact of the use of ordinary screw and guide rails after a period of time due to different wear levels of the screw and guide rails The problem of cutting accuracy.
