Rewinder Machine For Adhesive Tapes

Rewinder Machine For Adhesive Tapes

Rewinding Machine common fault - platen roller vibration
1. Proportional valve is unstable - cleaning proportional valve or replacing proportional valve
2. Damage to the top core bearing - Replace the bearing
3. The clearance between the support wheel and the guide rail of the core device is too large - Adjust the clearance (the core is clamped at both ends of the top core, 
and the eccentric shaft of the roller is adjusted to the gap between the roller and the guide rail is 0)
4. Guide rail wear - replace or repair the rail
5. Paper core deformation - Replace the paper core
6. The top core device supports the wheel bearing or the copper sleeve wear - replace the support wheel bearing or copper sleeve
7. The thickness of the paper is different - the production process is solved

Design and application of constant tension and load distribution control for winder---

1. Rewinder structure and working principle

1.2 Working principle
The paper web is taken out from the paper take-off roller (in this paper, the lower paper feeding method is adopted), and the paper guide roller passes through the slitting mechanism, and is wound from the bottom between the front and rear bottom rollers, and then wound on the paper core. There are 1 support rollers in front of and behind the slitting mechanism, and the front and rear support rollers are equipped with tension sensors for measuring the tension of the web. The platen roller above the core ensures the hardness of the roll. Each component of the winder is driven by a separate motor. The working principle is 3: the original paper roll taken from the paper machine is placed on the unwinding roller, and the brake on the unwinding roller maintains a certain tension of the paper web, and Quickly brake the paper roll when the head is broken. The paper web passes through the guiding roller to reach the slitting device, and several slitting circular cutters divide the paper into the required width, and then send it to the take-up roller for rewinding. After reaching the specified length, the paper is stopped and replaced with a new paper core. Repeat the above process. The main structural parameters of the winder are the width of the paper that can be processed and the maximum speed, followed by the maximum diameter of the paper and roll, the method of cutting and the length.
It can be seen from the working principle of the winder that the motor of the take-up roller drives the corresponding take-up roller to rotate the paper-wound paper core, the diameter of the paper roll gradually increases, and the axial center of the paper roll increases with the diameter. Gradually moving up, the platen roller moves up and gradually reduces the pressure. The unwinding motor mainly provides a reverse torque, creating tension on the paper surface, keeping the paper web flat, and the speed control of the unwinding motor is a process of gradually increasing speed, but the linear speed of the paper web remains unchanged.

Belt rewinding machine design and working principle ---

6 nipple guardrail
The nip guard is a sturdy mesh protector located between the belt roller and the unloader. The nipple guardrail acts as a protective device during the rewinding process. It prevents contact with rotating sticks.
Construction
The vertically moving fence is controlled by hydraulics. In the upper position, the safety lock prevents the fence from falling. When the guardrail falls, the cylinder compression safety lock opens.
working principle 
The nipple is in the upper position when the reel is stopped. When rewinding, it must fall or the winder cannot be turned on.

7 paper feed roller
The reel is moved from the roll to the unloading station by a hydraulically controlled ejector mounted on the frame.
The minimum roll diameter that the pusher roll can be pushed open but cannot be pushed open with the smallest roll is 400 mm (15.7 in)
