Paper tube machinery and equipment are used to manufacture paper tubes. The paper tube manufacturing equipment is fully automatic. The paper tube machinery and equipment are fully automatic in cutting and dropping the paper tube. Because paper tube machinery has so many advantages, it has been applied in many and many industries.
        Paper tube machinery and equipment will automatically stop working to avoid more serious accidents. A common problem when paper tube machinery and equipment are used to produce paper tubes is that the paper is out of paper. Paper tube machinery and equipment are performing paper tube alignment. When cutting, the speed will be changed automatically and the corresponding response action will be made automatically.
        The overall performance of paper tube machinery and equipment is still very good. The high carbon steel knife and polyester rubber knife used in paper tube machinery and equipment are very durable and stable. The paper tube machinery and equipment also have the function of automatic gluing. It is possible that the continuous knife phenomenon of paper tube machinery and equipment is because the limit switch cannot be controlled. Once this situation occurs, it is very easy to cause the buttons of the paper tube machinery and equipment to be unusable. Very easy to get an electric shock.
        Common types of friction and loosening of paper tube machine parts are spring washers, double nuts, oval-shaped self-locking nuts, and cross-cut nuts.

        Spring washers rely on the elastic reaction force generated by tightening the nut to flatten the washer to maintain a certain additional friction between the thread pairs. At the same time, the sharp edges of the washer cutouts against the nut and the supporting surface of the coupled part also prevent loosening effect. This method is simple in structure and easy to use. The disadvantage is that the load is shifted to one side, and it is not reliable to work under shock vibration. It is generally used for less important connections.
