Compared with the old-fashioned paper cutter, the program-controlled paper cutter has better accuracy, which mainly comes from the precise control of the built-in program. Secondly, due to the positioning of the program control, the coordination between paper cutting and paper feeding can achieve three to five times the efficiency of ordinary mechanical paper cutters. In addition, since the program-controlled paper cutter is operated autonomously by the programs that have been set internally, no human intervention is required, and a large amount of labor and labor intensity can be liberated to a large extent, and all the paper cutting procedures are completed independently. , No need for secondary positioning.
        In terms of operation, the all-Chinese operation interface makes the human-computer interaction more friendly and simple. And the automatic control of the system program allows the user to realize the automatic production only by inputting the program through the operating system of the machine, and learn the program making bit by bit.

        How to replace the cutter of the paper cutter? Due to the use of high-efficiency flat envelope toroidal worm reducer, it is not self-locking, the main motor stops, and the cutting switch selection switch is pulled to the tool change position, the drive has lost its control. The safety device has lost protection, and the cutter bed may slide down in a stationary state, which may seriously endanger safety. Therefore, in this state, it must be confirmed that the cutter bed stops reliably, and the wood pad under the blade can only be operated below.
        When changing the cutter, first turn off the main motor, wait for about 2 minutes, and confirm that the drive belt has completely stopped running, place two wooden tool changers (provided by the manufacturer) under the blade, and switch the cutter on the switch panel The selector switch is placed in the tool change position. The tool bed function selector switch must be in the cutting position. Use a sleeve to rotate the end nut of the pulley, remove all the connecting screws on the blade, and then use an allen wrench to push the knife hanging device inward for about 4MM. Disengage the brake of the knife-hanging device, rotate the knife-hanging device to make the blade fall smoothly on the two wooden tool changers, install the two tool-changing handles, remove the blade, and pay attention to holding the blade to prevent it from overturning and hurting people.

        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.
