The sharp effect of the cutter of the program-controlled paper cutter and the service life can greatly affect the production efficiency of this paper cutter. The life and effect of a knife depend on several factors, such as the material of the knife, the shape and angle of the knife, the quality of the knife, and the type of material being cut.
        In the material of knife making, the material of the blade should be relatively high hardness chromium tungsten manganese steel, and the blade body can be made of low carbon steel. If it is a high-quality blade, it can reach a certain hardness after being subjected to a fire extraction process.
        In the shape and angle of the sharpening knife, if the angle of the sharpening edge on the knife is relatively small, its blade edge will be sharper. Therefore, as far as the cutting tool material allows, the sharpening angle should be as small as possible.
        The quality of the sharpening knife mainly depends on the technical level of the operator. If you feel the quality is higher, the longer it can be used.

        Three major obstacles encountered in the development of program-controlled paper cutters:
        1. The control system is relatively backward and lacks automatic detection devices. In terms of system control, when China began to use PLC, computer control has been fully adopted in foreign countries. Computers are used to monitor and adjust various actuators. At the same time, parameters can be preset. Automatically adjust the nodes under control, greatly reducing the auxiliary time, and ensuring work efficiency and reliability.
        2. It is difficult to make a set. Domestic paper cutter equipment can rarely be matched with peripheral equipment to form a cutting production line.
        3. There is a gap between appearance and ease of use. After continuous efforts and development in recent years, the gap between the products produced by domestic program-controlled paper cutter manufacturers and foreign products is rapidly narrowing, and some technologies are even at the leading level. Abroad is basically microcomputer program control, but China is still mainly digital display control, and various mechanical paper cutters on the market that lack security protection measures are still everywhere. Computer-controlled paper cutters are a development trend and will replace other paper cutters in a large area.

        Working principle of paper cutter:
        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 paper is inserted into the device, the cutter will automatically cut. Some cutters need to press the start key once, and the cutter will rotate to continue cutting. After cutting the paper, press the Stop / Reverse key to stop the cutter from turning.
        The working principle of the separator:
        1. Fixed-length slitting of the entire roll or sheet of raw materials, such as plastic packaging materials, packaging cartons, steel plates, films, leather, wood chips, etc. for slitting processing. Fixed-length slitting control is required.
        2. The slitting length can be set continuously. If there is an error in the actual slitting length, it is easy to calibrate by setting parameters.
        3. The slitting control of the paper slitting machine is divided into two types: static and dynamic slitting: when the set length is reached, the machine will stop accurately, and then the static slitting will be processed. After the slitting, the operation will restart; When the machine stops, it sends a cutting signal, and the cutting machine dynamically cuts and cuts during the movement of the material.

        The paper cutter industry has been developing very strongly in recent years, especially in the current market of the fittest. The competition between various manufacturers has evolved to the competition on the market. From the initial equipment room paper cutter, to the electric paper cutter, to the current digital display paper cutter, it can be described as very fierce.
        In the development of the printing industry in recent years, the development market of paper cutters is very broad. Therefore, in the competition, paper cutter manufacturers want to save first in this vortex. Products, new technologies, and reasonable use of resources to create high-quality products can occupy a place in the market.
        In addition, the development direction of the paper cutter industry largely depends on the situation of the printing industry and the packaging industry. This is mainly because the paper cutter is an indispensable device in the packaging industry and the first brush industry. According to the existing market, the development of paper cutting machines is no longer as simple as paper cutting. It needs to integrate various functions, such as high intelligence and high precision, which can effectively improve work efficiency and save resources. Only in this way can the paper cutting machine industry have more advantages.

        The paper cutter mainly includes two aspects of cutting method and proper cutting height in standard operation. In the current paper processing industry, the operator of the paper cutting machine will use the simplest and most labor-saving method to complete the cutting task for the use of the equipment. The returned product is not accurate and can be reworked. It can be said that it is a kind of operation that pays for itself.
        Therefore, for the operation mode of the paper cutting machine, the staff should carry out the correct application, especially according to the state of the equipment to select the appropriate cutting mode. The cutting height is also very important for the accuracy of the equipment. The larger the cutting height, the greater the error for the top and bottom samples. Therefore, for proper cutting height, it is very important to ensure cutting accuracy.
        Every operator in the paper processing industry should set a suitable cutting height according to the working status of the paper cutter and the cutting object, to ensure that the error between papers is within a proper tolerance.
