Guolian High Speed ??Slitting Rewinder Technical Description ---
The specific technical structure is described as follows:
2. Paper cutting department:
It is mainly composed of independent frame, guiding paper-feeding roller, segmented and extended arc roller device, front and rear segment guide roller, bottom knife device, round knife device and paper suction fan.
The frame is welded by steel plates and is heavy and sturdy, completely independent of the take-up frame, avoiding the effects of possible vibration on the paper cut.
Guided paper roller, diameter Φ700mm, material Q235, directly driven by motor, chrome-plated surface, hydraulic disc brake and vertical adjustment device, can be adjusted along the scale with worm gear system to adjust the tension of the paper web, adjustment range It is ±25mm. The large diameter guide rollers also facilitate smooth and high speed operation of the equipment and paper web. The bottom knife device, the round knife device and the front and rear segment guide rollers form a paper cutting platform to ensure that the width direction of the paper cutting is even and even. There are 6 sets of cutters, top knife φ180mm, bottom knife φ200mm, each bottom knife is driven by a variable frequency motor, the cutter is automatically positioned, and the cutting servo width is automatically adjusted by the control servo system. The entire slitting system assembly (including tool holders, guide rails, etc.) is imported from abroad to ensure its stability and reliability. The segment guide roller before and after the cutter has a diameter of φ198mm and a roller material Q235, which is divided into 5 sections. Each side of the cutter is equipped with SKF bearings. The surface of the roller body is grooved and the surface is chrome-plated. The circular knife device is composed of a cylinder, a sliding seat and a round knife, and is fixed on the circular beam beam guide rail. The feeding knife and the knife are controlled by the cylinder. After the starting, the two sides of the knife start to cut the paper edge, and the other round knife is given by the operator. After the command is fed, when the paper breaks, the air source of the middle circular knife is automatically cut off by the main control command and automatically raised. There is a web stabilizer plate on each side of the knife to guide the paper edge.
Before the paper cutting table, a set of segmented stretching roller system is installed. The diameter of the stretching roller is φ198mm, the material of the roller body is Q235, and the surface is chrome-plated. The total length is 19 segments. The curvature of the multi-stage roller can be adjusted before and after the hand wheel to ensure the paper web. smooth.
The suction paper edge device on both sides of the longitudinal cutter uses a special fan to break the paper edge, which makes the suction effect better, and is also beneficial to the next processing of the waste paper edge. Fan motor power 37KW air volume 11000m3 / h.
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.
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.
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)

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.
