Rewinding Machine safety operation guide - 

Seventh, production operations and quality control during the rewinding process:

4, pay attention to the quality of the rewinding of the paper roll when rewinding, found zigzag, knife, running,
If the color difference is serious, skipping, chain printing, wrinkling, violent edge, etc., the result should be stopped in time. Only after the inspector confirms can the machine be re-rolled.
5. When the rewinding operation is running, the host must be at the console, and must not leave at will to prevent accidents. Transport
The speed of lifting and lowering is slow, and the speed of the vehicle cannot exceed the prescribed limit.
6. When loading the paper core tube, it is necessary to select the paper core with the same outer diameter and the length specification in line with the quality standard.
The installation of the cylinder requires a large deviation of the outer diameter and needs to be replaced.

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.

Belt rewinding machine design and working principle ---

12Paper roll holder
When the paper roll is stopped, the paper roll is fixed at a certain position by the paper roll holder. The paper roll holder prevents slack and lateral movement of the paper roll. It is important to make a joint when making a customer roll. Roll holder on the take-up roll
The paper roll holder on the paper roll includes a spring-loaded plastic roll mounted on the paper cutter frame. When the paper cutter is in or on the middle position, the paper roll holder is placed against the surface of the rear bottom roller.


13 Automatic roll change
The rewinding device removes the paper roll from the winder.
The rewinding device cuts the sheet, pushes the paper roll onto the unloading station and fills in a new core for the rewinding.
The roll change can be started when the roll is decelerated. In the final stage of deceleration, the nipple guardrail and the platen roller rise to a high position. The unloader rises to the position where the paper roll is received. When the winder stops, the paper core clamp opens and rises to rise. The paper cutter is raised from between the paper rolls. The paper feed roller pushes the paper roll to the paper unloading station. At the same time, the paper cutter cuts the paper. The vacuum suction of the rear bottom roller sucks the cut sheet onto the roller. The core loader drops the new core onto the roll. The paper feed roller returns to its original position and the unloading table falls to the middle position. The paper core clip is lowered and closed. The platen roller and the nip guard are lowered. The winder crawls at a speed.
