Rewinding Machine common fault - The coil is not tight during operation
1. Unwinding tension controller is not open - Open unwinding tension controller switch
2, did not press the reset button - press the reset button on the two tension controllers
3, the unwinding tension controller tension is too small - increase the unwinding tension controller output current
4, tension controller failure - contact the manufacturer
Rewinding Machine operation safety regulations -
First, the preparation work before starting
1. Clean up the dust on the machine;
2. Check the circuit of the machine (whether the circuit is damaged), whether the rotating parts (bearings, gears, etc.) are loose, whether the conveying belt is intact, whether the protective device is intact, if there is an abnormality, it needs to be replaced or reported to the workshop supervisor in time;
3. Is the amount of lubricating oil (butter, oil) of the rotating parts of the machine appropriate? Is the amount of white mineral oil on the perforating knife appropriate? If not enough, add the right amount of oil;
Rewinder mechanical structure and control process ---
As the last process in the papermaking industry, the winder is the fastest running machinery in papermaking machinery. Its speed can reach 1500~1800m/min or even the speed can reach 3000m/min or more. The winder is in the papermaking industry. The important role that can not be ignored, the paper roll from the paper machine must be rewinded by the winder to get the finished paper roll we need, and the quality of the finished paper roll is not only determined by the paper machine, The role of the winder is also of particular importance.
The working principle of the winder is to install the large paper roll produced from the paper machine on the paper exit frame of the winder. In order to maintain a certain tension of the paper web, the brake device must be installed on the paper return frame. A brake motor is installed on the paper exit frame. If the paper breaks during the rewinding process, the brake device can also brake quickly to reduce paper loss. The web is cut to the width we need by the slitting roller, the paper guide roller and the winder slitting mechanism, and then re-rolled into a paper roll according to the required tightness and the diameter of the finished paper roll. The main structural parameters of the winder are the width of the paper roll that can be rewinded, the maximum speed that the rewinding machine can reach, the quality of the finished paper roll, the maximum diameter of the ejecting roll and the roll paper, and the method of cutting the paper.
There are many types of rewinders, and other devices can be equipped in the rewinder as needed to become a joint machine. The rewinder can basically be divided into the following five types: upper paper rewinder, lower paper rewinder, single roll rewinder, special rewinder and thin paper rewinder. Since the research object of this subject is mainly for the lower threading rewinding machine, the introduction and explanation of the double bottom roller lowering paper rewinding machine will be given.
