Rewinding Machine common fault - Longitudinal cutter swing
1. Round knife bearing wear - Replace the bearing.
2. Tool holder sliding bearing wear - Replace the bearing.
3. Lock the cylinder leak - replace or repair the cylinder.
Rewinding Machine operation safety regulations -
Second, the operation steps：
7. When the layers of paper are completely flat and enter the rewinding, the waste coils are taken out to the normal production state. 8, check the production situation:
(1) Check whether the two ends of the base paper are symmetrical. For example, the auger can adjust the auger on the unloading frame to the ends of the paper. (2) Check whether the punched paper is clear, the punching is not clear or the missing teeth are checked. Whether the knife is broken or not
Whether the wire is loose, adjust the height of the bottom knife, and mass production after inspection;
(3) Check whether the paper feeding tension of the rewinding paper is consistent, keep the paper surface flat and no wrinkles, such as inconsistency
Then adjust the paper return belt hand wheel on the paper exit frame;
(4) Check whether the paper between the embossing stick and the winding area is flat and tight, if it meets the requirements, if it does not meet the requirements,
Then adjust the gearbox handwheel (when adjusting the gearbox handwheel, you can't stop the adjustment, you need to turn it on slowly); (5) Check whether the semi-finished paper roll is tight, the diameter and weight meet the product standard requirements, and the two ends are neat (straight
The deviation of the diameter shall not exceed ±1mm, and the weight deviation shall be within ±2);
(6) Whether the width of the glue seal of the paper ball meets the standard (package standard is 10mm-15mm), the penetration of glue
No more than 3 single-layer papers;
(7) Do not arbitrarily tamper with the inverter, programmed wiring and settings in the electric box; (8) Non-operator operators must not let the machine operate without the consent of the supervisor;
Third,. After the above steps are checked normally, Slowly speed up to normal operation.
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.
