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.

Second, the main structure of the winder

2.3 Rolling Department
1. Stretching device
The stretching device of the rewinder is set to keep the paper web slit after slitting. In some paper cutting knives, the stretcher is also used. The main function is to eliminate the texture and slack of the paper web. Mainly, it can maintain the good operation of slitting. There are three types of stretchers that we often use today: D-shaped stretches, curved rollers, and Z-type double-bar stretchers.
2, support roller
The backup roll is mainly used to support the paper roll, which is composed of a controlled cast iron roll or a general tube roll. The roller body is mainly cast iron pipe and steel pipe, and its diameter is usually 400-700 mm or more according to the width of the winder. The center-to-center ratio between the rolls of the backup roll should be greater than the roll diameter. Only at such a distance, the roll core does not get caught in the middle of the roll when the support roll begins to curl.
When the winder is running at high speed, in order to avoid vibration during high-speed operation, the design of the backup roller must be minimal when supporting the paper roll. The radius is a function expression of the speed and width of the winder, mainly by allowable The critical speed and the degree of winding are determined because at this time the diameter of the backup roll has less chance of producing a defect in the roll hardness than the small diameter support roll. When coiling coated paper or very thin paper, we should consider using a larger diameter backup roll. On a rewinder with a small width, we generally use a 600mm roll diameter.
