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.
5.1. 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.
Guolian High Speed ??Slitting Rewinder Technical Description ---
The specific technical structure is described as follows:
4, the coiling department:
Mainly by frame, bottom roller device, pressure roller device, head lifting device, paper core plug clamping device, head lifting device, paper roller ejector, cutting knife, automatic paper web clamping device, automatic paper changing device, paper Core positioning device, paper unloading table device, paper stop roller device and perfect safety protection system.
The frame structure is welded with high-quality steel and is heavy and strong.
The bottom roller device is composed of front and rear bottom rollers, hydraulic disc brakes, motors, reducers and the like. The bottom roller adopts SKF bearing and Q345 coil processing. The front and bottom rollers are sprayed with tungsten carbide and the thickness is 0.08mm. The rear bottom roller has a special spiral groove composed of three spiral curves, and the outer diameter is φ850mm.
The pressure roller is mounted on the pressure roller beam with a diameter of φ290mm. It is made of seamless steel tube and has a chrome plated surface. It is divided into two sections and is driven by a double motor via a belt. Both ends of the pressure roller beam are equipped with a synchronizing device and a safety locking ratchet, a roller position fine adjustment device, and a pressure sensor and a displacement potentiometer for measuring the diameter of the winding roller. The wear-reducing roller is mounted on both ends to contact the guide rail to minimize the friction. The up and down movement is directly driven by a large stroke hydraulic cylinder, and the pressure roller re-pressing device adopts an imported servo valve to realize automatic control of the whole process of the pressure of the pressure roller, and the control precision is high, and the pressure value can be automatically adjusted according to the difference of the roller diameter. The platen roller is equipped with a variety of pressure programs that can be selected by the user depending on the type of paper. In special cases, manual operation is possible. On the basis of the adjustment by the pressure roller, according to the increase of the roller diameter, the torque difference between the two bottom rollers is automatically changed, and the inner tightness of the appropriate finished paper roller is obtained.
The head lifting device is directly controlled by the hydraulic cylinder to move up and down along the guide rail. When the paper is normally wound, the hydraulic cylinder pulling force only offsets the gravity and friction force, so that the radial force of the paper core is reduced as much as possible.
The paper core clamping device uses a cylinder to clamp the paper core to prevent axial movement of the paper core during the winding process. It also has a handwheel adjustment mechanism that fine-tunes the position of the core.
The paper core holding device rotates around the center of the front bottom roller, and the paper core is fed by the automatic paper feed core device, and the paper core is pushed into the robot slot in the holding device. After the roll of the paper roll is completed, the web holding device is raised, and the web is pressed against the back bottom roll to maintain the tension of the web. The paper roll ejector pushes the paper roll away from the rear bottom roll, and the cutting knife quickly pops up to cut the paper web. At the same time, the paper roll ejector smoothly pushes the paper roll into the paper discharge hopper. Then, the automatic paper changer device is raised, a new paper core is placed, and under the synergistic action of the air nozzle, the paper head is automatically wound into the paper core to complete the paper core replacement and the next roll paper is carried out.
The core positioning device is located in front of the front bottom roller. On the operating side, the cylinder is driven with a ruler and when the core is pushed in, it is dimensioned to match the size of the front cut.
Both the paper roll ejector and the unloading table are hydraulically driven and controlled, and the action runs smoothly. The unloader has side guards.
The paper stop roller frame device is located in front of the finished paper roll, and prevents various dangers to people and equipment caused by various reasons such as sudden flight of the paper roll during normal operation. It is mainly composed of a bracket, a synchronizing device, a safety locking ratchet and the like. Directly driven by the cylinder, the safety lock ratchet is automatically controlled by the cylinder to prevent the paper stop roller frame from falling suddenly due to unexpected events such as oil leakage.
Safety protection system, including a large number of limit switches, safety doors, interlocking photoelectric protection devices, various locking mechanisms, warning signs, etc.
What is a fully automatic winder---
The shortage of workers and the lack of employment are the actual problems faced by enterprises in the current period. In addition to the fierce competition in the current market price war and other factors, it is undoubtedly worse for enterprises. Transforming and upgrading equipment is fundamental to reducing costs today. For the needs of the market, our Zhengzhou Guolian Machinery Factory is in a hurry to develop the plastic machinery supporting equipment ------- automatic rewinding machine.
Automatic rewinding machine - role and purpose
Instead of the previous manual and manual semi-automatic secondary rewinding. It effectively improves work efficiency, reduces and saves the problem of labor and workers' wages, and is a fully automated production supporting equipment that is indispensable for enterprises to directly reduce production costs.
Automatic rewinding machine---function and use
In order to meet the different needs of customers for the length and width of the product. Carrying on cling film, wrapping film, stretching
Secondary rewinding of film, aluminized film, paper, non-woven fabric, etc. Replacing previous manual operations and manual semi-automated work.
