Rewinding Machine common fault - Rolls are not collected
1. The original coil is not uniform - Finish the original coil to ensure that the original coil is neat
2, paper core size head - check the paper core
3, only start a short period of time - normal phenomenon,
4, bearing damage - bearing damage is often accompanied by abnormal noise, pay attention to check the bearing, found that the damage is replaced in time
5, shaft damage - contact the manufacturer
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 ---
Second, the main structure of the winder
2.3 Rolling Department
Nowadays, with the increase of the speed of the winder, most of the winders are equipped with unloaders, which are used to push the rolled paper rolls from the support rolls and unload them on the ground. It has many forms, the most common ones are the unwinding station and the unwinding pendulum. Its control mainly depends on air pressure or hydraulic pressure. The thief of the unwinder can be selected according to the number of operators, the size and quality of the core. The advanced foreign rewinding machine can automatically control the positioning of the mandrel and mandrel and the cutting of the paper, which can save auxiliary operation time and improve production efficiency.
4, transmission mechanism
The speed of the paper-feeding machine of the winder is generally about 15 to 40 m/min. In the process of raising the speed of the paper from low, we require the speed of the vehicle to rise, so that the paper roll can be avoided due to the fluctuation of the tension. The tightness is inconsistent. Uniform acceleration is required for breakage or shutdown. During the acceleration process, the average acceleration is usually 0.23~0.37m/s, and the acceleration time is usually 50~60s. In the braking process, the deceleration is 0.42~0.75m/s and the braking time is 40s. In order to meet the shifting requirements of the winder, most of the rewinding opportunities are driven by DC motors. In the previous rewinding system, a DC motor generally controlled two supporting rollers, and in the current rewinding machine, Development and research have started with two separate motor control rolls, which can control the speed difference between the two rolls, which is beneficial for taking up the appropriate tightness of the paper roll.
