Mini Paper Roll Rewinding Machine

Mini Paper Roll Rewinding Machine

Rewinding Machine operating procedures -  Start roll paper
1. The main operation starts the power-on signal and enters the roll paper state.
2. First set the information (length, diameter) of the paper roll to be rewinded.
The tightness of the paper roll adjusts the amount of tension.
3. Generally, the starting speed of the roll paper is set between 30 and 50 meters.
Step up speed, while speeding up, pay close attention to the subtle realization of the roll paper surface, such as pleats, twisting, knife edge biting, etc., should be adjusted in time to ensure the quality of the roll.
4. When the rewinder is in the normal roll, the paper will suddenly be broken due to paper disease or other reasons. The main operation will immediately press the stop button.
5. Connector
5.1. After the rewinder is stopped, first find the cause of the broken broach, make a broken record, and strip the external waste paper of the roll;
5.2. Instructing the main operation to start the paper feed;
5.3. After the paper web is placed on the paper, the paper is broken at the end of the paper and folded with a knife.
5.4. Pull the tape off and place it under the cut paper web. The length of the tape is two centimeters on both sides of the paper web. Cut it with a blade, then use the hand to pull it up to get the paper web to be pulled up and flattened, taped on the tape, paper. Align the interface, cut the long paper web with a knife, and finally level the adhesive tape with your hand. Immediately after the completion, remove the handle and notify the main operation to lower the platen roller and start the roll paper.
6. The main operation is strictly controlled according to the diameter and length required by the process standard. When the length standard is reached, the vehicle speed can be smoothly decelerated and the rewinding is completed.

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

1. Rewinder structure and working principle

1.1 Structure
The rewinder is generally composed of a unwinding roll (also referred to as a paper take-off roll), a guide roll, a slitting mechanism, a platen roll, a take-up bottom roll (including a front bottom roll and a rear bottom roll), and a double bottom roll. The machine is characterized by two rotating drums to replace and support the take-up reel, usually with or without a rotating platen roller pressed against the top of the reel in the take-up, the take-up reel is taken up The main structure (has become the front and rear bottom rollers respectively). Under normal circumstances, the surface of the front bottom roller is rough, and the surface of the rear bottom roller is relatively smooth. They are connected to the motor through the reduction gear box. The platen roller, also called the load roller, acts to create a downward pressure whose pressure is the difference between its own weight and the load roller lifting pressure. The unwinding roller is composed of a leg paper holder, a unwinding roller coupling, a unwinding roller clamping mechanism, and a unwinding motor. Longitudinal cutters generally have book holders side by side on the same axis, mainly used to cut off the change. Cut a certain width of sheet paper to the required width as needed. Two tension sensors are placed on the tension roller to receive the web tension.

Belt rewinding machine design and working principle ---

1 belt roller device
Structure
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
4- belt
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.
