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.
Rewinding Machine operating procedures -
First, the boot process:
8, set the minimum winding diameter of the shaft, the size is generally 5mm based on the diameter of the core;
9. Open the detection software and load the corresponding product template;
Note: If it is a new product, please model according to the product modeling method, then load the template; 10. Create a new train and start testing;
11. Select the running direction and press the run button to resume the normal operation of the winder.
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.
