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 an infrared electronic control system and electronic safety during operation 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.
        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 rewinding. 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.
        4. Comparison of energy consumption
        The paper cutters of the same model also need to be compared in the application power of the whole machine. Motor power is not only related to power consumption. Due to the reason of precision matching in the process of machine manufacturing and assembly, it is necessary to choose a motor with a larger power, which is actually a method that cannot be dealt with in the process of mechanical processing and assembly.
        5. After-sales service

        When choosing a paper cutter, it is also necessary to weigh the after-sales services of the consumer manufacturers. A good manufacturer will definitely think about the distribution of after-sales service outlets to enable customers to receive satisfactory service and technical support in the shortest time. The detailed performance of the comprehensive capabilities of the machine manufacturer.
