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.
Four release and one rewinding machine operation program ---
Fourth, normal shutdown and emergency stop
1. The emergency stop is faster than the normal stop speed. After the stop, the traction roller is automatically raised. The self-locking button is urgently deactivated. In the state of emergency stop, the machine cannot be started. We need to unlock the emergency stop before the machine can be started. . When the machine does not start (observe whether the start indicator is lit), we check the status of each emergency stop button.
2. When the discharge roller is about to release the material, it must be decelerated in advance. It is guaranteed that the speed of the material is just zero when it is finished.
3. Deflating Adhere the material on the receiving roller with tape, open the pressing shaft, lift the receiving roller, place it on a stable place, deflate the receiving roller, and pull out the receiving roller.

Second, the main structure of the winder
2.4 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 slips because the paper roll is too light, and the winding is too tight because the pressure is too high until the rewinding to the later stage. In the modern rewinder system, the platen roller is automatically controlled, so that the paper can be additionally applied. 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 transmitted to the pressure program control unit to calculate the pressure, so that the oil pressure in the suspension scale can be changed, thereby achieving pressure control of the platen roller.
