Film Slitter

Film Slitter

The rewinder is a special equipment for mica tape and film. The rewinding process mainly accomplishes three tasks: first, cutting off the raw paper burrs; second, cutting the whole original paper into 
a plurality of widths in accordance with user specifications; Third, control the winding diameter of the finished paper roll to meet the factory specifications.

 

Advantages of the winder
1, equipped with processing unintentional, solid, paper tube toilet paper, can instantly switch between products. 2, automatic trimming, glue spraying, sealing, and the shaft is instantaneously synchronized, so that the paper is transferred into the band saw and the paper is not damaged when it is cut.
3. Pneumatic belt feeding, double reel and each axis of the original paper have independent tension adjustment mechanism.

Guolian High Speed ??Slitting Rewinder Technical Description ---

The specific technical structure is described as follows:

Part 1: Mechanical parts
The mechanical part mainly consists of a paper exiting section, a paper cutting section, a double curved roller section, a paper winding section, and an automatic paper guiding section.
1. Ejection department:
The structure is all welded by steel plate, equipped with an empty paper roll temporary storage guide rail. The paper-removing roller is locked on the paper-removing frame by the hydraulic operating lever. After the paper is finished, the paper-returning core is pushed onto the guide rail to replace the paper. Roll and start-up operation saves time. A bumper is attached to the end of the exit frame rail to reduce vibration and noise caused by the roll change.
The coupling clutch is located between the paper roller and the brake motor, hydraulically operated, and is interlocked with the hook safety anti-lift device. The crane hook cannot lift the empty paper return shaft before the roll paper completes the clutch has been disengaged. Security performance.
With brake generator drive and hydraulic control, the paper return frame is horizontally adjusted by hydraulic motor and has a lateral swing function with a maximum swing of ±50mm. The emergency brake uses a brake generator and a hydraulic disc brake. The brake is imported from abroad, with small volume, large braking torque and good reliability.

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.
