1. Security
        The paper cutter is different from other mechanical products. It belongs to the fourth-level dangerous machine tool with the highest danger level. When selecting a paper cutter product, it is necessary to focus on its safety and reliability. Such as whether the paper cutter presser has a fall prevention device; whether a fully enclosed safety cover is installed at the moving parts to prevent accidental breakage of parts and components and cause personal injury; whether the cutter has an infrared electronic control system and an electronic safety knife during operation Lock etc. to prompt the safe range.
        2. Mechanical structure
        The earliest mechanical paper cutter uses spring pressure to press the paper, and the slider is used to push the paper. The structure is relatively simple, the packaging of washing supplies, and the commissioning and maintenance are also relatively convenient, but the pressure of the paper is small, and the cutting accuracy is poor. It cannot meet the requirements of high-level printing on paper cutting accuracy, and it cannot meet the requirements of medium and high-end packaging and printing products.

       When it comes to products like program-controlled paper cutters, most people can think of just the function of cutting paper. In fact, the function of the program-controlled paper cutter is really just cutting, but the object it faces is not just paper.
        The place where ordinary people can see program-controlled paper cutters in life is nothing more than print shops, bookstores, etc., and most people's impression that program-controlled paper cutters can only cut paper also comes from here, because these two places purchase program-controlled The purpose of the paper cutter itself is to cut the paper.
        In other places, such as some large printing factories, although some of the program-controlled paper cutters in these places are also used for cutting paper. But the materials printed in these places are not only paper, but also fabrics. In other words, in these places, the program-controlled paper cutter even cuts leather and fabric. These program-controlled paper cutters are actually customized by manufacturers, so these special products are rarely seen in the outside world.

        What should I do if the photoelectric protection function of the paper cutter fails? Remove the circuit board and carry out a visual inspection. It is found that the substrate around the power bridge pile is discolored, and it is concluded that the bridge pile is burnt out. The bridge pile is powered on and tested, and there is still no response.
        Measured with a multimeter, the newly replaced bridge pile has also been burned out, thus judging that there is a short circuit part. Checking the components one by one from the bridge stack, it was found that a three-terminal voltage stabilizer block (7805) was broken down, the component was purchased to replace, and the power indicator on the circuit board turned on after powering up. The operator installs the circuit board on the machine, and operates according to the normal procedure to check whether the photoelectric protection function is working, covering the optical eye with his hand, and the falling knife stops immediately. After several attempts, it is normal. The fault is eliminated.

        How many steps are there in the operation process of the electric programmable paper cutter? Today, the editor will give you a specific talk
       Operation process of program-controlled paper cutter:
       1. The operation process of the program-controlled paper cutter manufacturer should check the machine and do the cleaning work before starting, add oil or butter, try the empty knife three times, and observe whether there is a return knife. If a problem is found, it should be eliminated in time. During the production process, if there is a return knife, you should park the car immediately and repair it in time.
        2. When working, you must concentrate, and it is strictly forbidden for two people to operate at the same time.
        3. When the machine is running, it is strictly forbidden to put your hand into the machine. If a fault occurs, it is strictly forbidden to grab the paper by hand, and you should stop the machine immediately.
        4. When the operation flow of the program-controlled paper cutter manufacturer is adjusted and the cutter is replaced, it must be stopped. Even when the machine is stopped, it is strictly forbidden to put your hand under the knife to change the knife. Long-handle bolts and other tools should be used to change the knife. The knife must be removed during the test to avoid accidentally hurting the operator when the machine is started.
        5. The machine must be cut off when adjusting the machine, changing the blade, and when repairing, refueling, scrubbing and inspecting the equipment.

        In the paper industry, a paper cutter is a device that can cut paper into flat paper. As a traditional product, the paper cutter is one of the most important equipments for printing, papermaking and other industries. According to the different cutting knives, it is divided into flick cutter and flat cutter. According to different control methods, it is divided into automatic paper cutter, program-controlled paper cutter, digital display paper cutter and so on. Different paper cutters have different uses, and the price of paper cutters also varies.
        During the cutting process with a paper cutter, the choice of the angle of the cutting edge of the cutting knife is very important. A good paper cutter needs to be equipped with a good blade and knife grinding process. Many users often ignore the problem of blades when using paper cutters. If the sharpening method, method, angle, etc. of the cutting knife are not correct, the impact during cutting will increase, resulting in loosening or even breaking of the safety screw, resulting in acute injury.
