In the long-term use of the program-controlled paper cutter, some faults may occur, such as the phenomenon of continuous knife. What is the continuous knife phenomenon? It refers to the fact that when the "Cut" button is pressed when the program-controlled paper cutter is operated, if the blade is not operating normally, or it is continuously operated more than twice. The continuous knife is mainly caused by the failure of the limit switch of the cutter, the sticking or lag of the upper limit switch or the relay contact. These failures affect the normal use of the cutter. The paper cutter manufacturer of Maoyuan will answer the reasons for the continuous knife phenomenon in detail for everyone.
        1. If the limit switch is not turned off, it means that the limit formation switch is out of control. Generally, the limit switch of the paper cutter has two contacts. As long as the idle group in the switch is used, the probability of power failure can be increased. Under the condition of constant costs, the contacts cause failure. The probability will be much reduced.
        2. The cutting control relay of the paper cutter is frequently used for a long time, which will increase the impact of the inductive high current, which will cause the cold welding of the contacts or the sluggish action. It is recommended to replace the contacts of the relay every few months.

        3. If the brake device is suddenly powered off, the socket is loose, etc., it will also cause the problem of continuous knife.
