Rewinding Machine safety operation guide -
Fifth, the tool change operation:
1. The bottom knife replacement is handled by the mechanic.
2. The rewinding machine must be stopped when the upper round knife is replaced.
3. After removing the round blade, replace the new blade and fix it.
4. Install the round knife seat, adjust the angle, and lower the round knife to make it close to the bottom knife.
5, running, paper test knife, paper edge is not, smooth.
6. The tightness and depth of the blade and the bottom knife should be controlled properly, not too tight, otherwise the new knife
The film will roll the knife; it should not be too loose, otherwise it will jump the knife and the hair; not too deep, otherwise it will cause double trimming; too shallow will jump the knife.
Four release and one rewinding machine operation program ---
First, prepare for inspection before starting the machine
1. Dust removal: Before cleaning, ensure that the work area is cleaned and there is no dust. There is no dust on the shaft. Clean it once with an air gun to remove the dust.
2, the direction of receiving and discharging: When unwinding the bar, pay attention to the direction of feeding. The discharge stick is counterclockwise. The receiving stick is clockwise.
3. The position of the gear and the position of the barrel are placed: the gear of the discharging stick and the receiving stick should be in the middle of the gear of the motor, avoiding the friction between the gear and the gear around the gear during the fine adjustment, thus causing damage to the gear or the motor; The receiving barrel should be the same on the scale of the stick.
4. Inflatable locking: After the position of the barrel is placed, use a high-pressure air gun to ventilate each barrel to ensure that each barrel is locked. (It is strictly forbidden to start the machine without inflation)
5. Induction: Manually pass the materials through the intermediate rollers and the tension sensor in sequence, and finally wrap the receiving core and fix the material head by hand. Note: Ensure that the material is neat and flat during the process of fixing the material. Put the material well and press the pressure shaft on the receiving roller.
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.
