Rewinding Machine operating procedures - Preparation for rewinding.
1. The crane operator and the rewinding personnel first check whether the information on the parent roll tracking slip on the base paper meets the requirements of the technical standards, specifications and specifications.
2. Check whether the labels of various paper diseases on both ends of the base paper roller are clear and consistent with the contents on the tracking sheet.
3. The crane operator should operate carefully according to the safe operation rules of the driving.
4. Place the base paper roll on the unloading frame smoothly, place the drum groove on the shaft head, place the track groove in the locked position, and connect it with the hydraulic coupling.
5. Jog the left and right shift buttons of the exit tray to bring the ends of the web to a position that can be trimmed (to be threaded).
6. The operator should make a detailed record of the paper (such as shift, shift, production date, roll time and paper roll code, etc.).
Rewinding Machine operating procedures - Start roll paper
1. The main operation starts the power-on signal and enters the roll paper state.
2. First set the information (length, diameter) of the paper roll to be rewinded.
The tightness of the paper roll adjusts the amount of tension.
3. Generally, the starting speed of the roll paper is set between 30 and 50 meters.
Step up speed, while speeding up, pay close attention to the subtle realization of the roll paper surface, such as pleats, twisting, knife edge biting, etc., should be adjusted in time to ensure the quality of the roll.
4. When the rewinder is in the normal roll, the paper will suddenly be broken due to paper disease or other reasons. The main operation will immediately press the stop button.
5.1. After the rewinder is stopped, first find the cause of the broken broach, make a broken record, and strip the external waste paper of the roll;
5.2. Instructing the main operation to start the paper feed;
5.3. After the paper web is placed on the paper, the paper is broken at the end of the paper and folded with a knife.
5.4. Pull the tape off and place it under the cut paper web. The length of the tape is two centimeters on both sides of the paper web. Cut it with a blade, then use the hand to pull it up to get the paper web to be pulled up and flattened, taped on the tape, paper. Align the interface, cut the long paper web with a knife, and finally level the adhesive tape with your hand. Immediately after the completion, remove the handle and notify the main operation to lower the platen roller and start the roll paper.
6. The main operation is strictly controlled according to the diameter and length required by the process standard. When the length standard is reached, the vehicle speed can be smoothly decelerated and the rewinding is completed.
Rewinding Machine Structure - Pressure Mechanism
1, the platen roller
First, in the rewinder system, the platen roller has a significant impact on the tightness control of the paper roll. Among them, the pressure adjusting mechanism plays a role of keeping the pressure of the paper roll and the supporting roll nip constant, and the main purpose is to prevent the paper roll from slipping or being wound too tight at the beginning of the work.
The paper roll is slippery because the paper roll is too light and the take-up is too tight because the pressure is too high until the rewinding to the late stage. In the modern rewinder system, the platen roller is automatically controlled so that additional weight can be applied to the paper web. The force.
2. Hydraulic (air pressure) suspension mechanism
Under normal circumstances, the adjustable pressure actuators use hydraulic suspension scale mechanism. We install a potentiometer attached to the platen roller to display the diameter of the finished paper roll, which is sent through the potentiometer. The signal is passed to the pressure program control unit,
To calculate the pressure, so that the oil pressure in the scale can be changed, thus achieving the pressure control of the platen roller.
