A paper cutting machine is an automated device that replaces people to complete this task. The paper cutting machine can reduce labor intensity and improve work efficiency. After digital integrated printing, the paper cutting machine will become another new product that enters the office or small printing industry. If there are double sheets or missing pages, it will automatically shut down and report errors.

This equipment can be used alone or in conjunction with offset printing equipment, greatly improving the quality and speed of paper cutting, making it the preferred equipment for large and medium-sized printing enterprises. During the operation of the paper cutting machine, the following problems often occur: the V-3-1/4B air valve of the paper cutting machine is faulty: the main problem is that paper scraps and dust enter the air valve sleeve, the air intake is reduced, and the pasting is not smooth. When encountering this situation, only the accumulated materials in the machine need to be cleared.

However, the cause of the damage may not necessarily be due to inspiration infarction, but it may also be due to improper disassembly and improper methods, resulting in damage to the valve sleeve. In advocating for open source and throttling, the purchase of gas valves costs tens of thousands of yuan and should be taken seriously. The correct disassembly method for an air valve is to remove it from the machine's working position, place one end of the valve body on one side of the jaw, and the other end of the screw against the front mouth. The main purpose of this is to increase the contact area of the screw, avoid breaking the valve sleeve, and also facilitate the removal of the circlip.

The problem with the hanging spring column of the paper cutting machine's teeth is mainly due to the excessive tension of the teeth pulling spring designed by the machine, which will cause friction between the teeth pulling spring and the hanging spring column. Over time, some movable sleeves that are held by the pulling spring will wear out. If the parts of the paper cutting machine are not replaced in a timely manner, it will have a serious impact. When replacing the screw, it is necessary to remove and remove the fan-shaped plate with broken wires as required.
