Rewinding Machine common fault - The coil is not tight during operation
1. Unwinding tension controller is not open - Open unwinding tension controller switch
2, did not press the reset button - press the reset button on the two tension controllers
3, the unwinding tension controller tension is too small - increase the unwinding tension controller output current
4, tension controller failure - contact the manufacturer
Automatic rewinding machine speed ratio adjustment method ---
2. Adjust the paper-pressing gap of the platen roller so that the paper web can be smoothly conveyed between the paper feeding belt and the winding roller. The rear platen roller is the intermediate link of the paper web conveying process. If the adjusted gap is too small, the paper web is easy to wrinkle and sag. When the gap is too large, the three layers of paper are not combined together to facilitate delamination and fault, which affects the speed of the paper feed and Rewind quality. When adjusting the paper-pressing roller, the paper-pressing gap should be gradually increased from small to large, so that the paper web can be locked without sag and not drooping.
Belt rewinding machine design and working principle ---
1 belt roller device
The belt and stick set consists of two belt rollers with intermediate and end supports! A rubber support belt surrounds the belt roller. The inner surface of the support belt has a guiding profile that controls the operation of the belt. There is also a correspondingly concave surface on the belt roller. The belt roller has been joined together by a rocker and a hydraulic cylinder from below. The belt tension can be adjusted with a hydraulic cylinder during the winding process.
The motor drives the rear belt roller to run, and the other roller is carried by the belt. The belt roller is equipped with a hydraulic brake system. The belt roller bearing housing is lubricated with lubricating oil. The oil flow and temperature of the lubricating oil system are detected by the sensor. There is a directional blow tube between the two rolls to ensure that no space remains in the space between the two rolls. The lifting device has been installed under the belt. The lifting device is used for changing rolls. The lifting device comprises a hydraulic cylinder and a lifting plate interlocked with the rear bottom roller during the lifting process.
Belt roller unit:
1- bottom roller
2- rear belt roller
3- front belt roller
5-belt telescopic hydraulic cylinder
Principle of operation
The core is placed between the back bottom roll and the back belt roll. The paper core is supported at that position throughout the initial crimping process up to a diameter of approximately 500 mm (17.9 in). The over 500 mm (17.9 in) belt begins to support the increasing area of ??the paper roll, and the weight of the roll is reached when the paper roll is particularly large. Mainly supported by a belt.
