It is a four-lobe type,hydraulic up and down, body up and Down Range Φ485-525mm, 50mm sleeve boots, suitable for opening Φ610mm inner hole roll material.

The verandah roll is driven by the motor through the gear reducer, the transmission gear, the tension is uncoiled, and the tension is adjusted by the knob at any time.

The foreground powertrain is equipped with a pneumatic butterfly brake, which brakes and aids in generating uncoiling tension.

Foreground hydraulic swing type pressure roller, pressure roller plastic bag.

Specifications: ac22kw.

Foreground spindle sank cylinder: Φ180x165 mm.

3, seven roller feeding machine

Use: mainly drag the coil on the uncoiler plate leveling make the slitting out of the plate more accurate.

By the motor, reducer, gearbox.

4, 1 pendulum bridge (Looper)

Uses: the transition material head or tail, the formation of material storage live.

Structure: the device consists of a pendulum Bridge and arc-shaped frame.

The foreground swing bridge is lifted or lifted by a cylinder, and all the covered rollers are covered.

The foreground is made up of a number of rollers, which are wrapped in polyurethane glue.

There are two pairs of material level detection photoelectric switch in the pit of the foreground, when the material rises to the position, the leveling machine drags the uncoiler to accelerate evenly;when the material level drops to the next position, the deceleration evenly.

5, correction feeding device

Uses: positive guide plate to ensure that the sheet does not go away and to the slitting machine feeding.

Structure: Correction Device by both sides of the guide roller, mobile slide, slide and adjust the hand wheel and other components.

Three sets of guide rollers on each side of the foreground.Adjust the hand wheel on the operating side while moving.

6.Slitting machine

Uses: the sheet lengthwise cut into various width of the Strip material.

Structure: slitting machine consists of a frame, the upper and lower knife shaft, knife shaft spacing adjustment mechanism and transmission system components.The upper and lower knife shafts are active rotation, by the AC motor, reducer, gear distribution box and universal joint drive.

Foreground by worm electric adjustment to change the knife shaft pitch to adjust the amount of Blade overlap.

Several cutter heads and a range of spacers of varying thickness are mounted on the cutter head shaft, and the cutter head and spacer are pressed by a nut.

At the time of tool change, the movable support is opened by a hydraulic cylinder along the base guide rail, and the knife shaft is supported on the fixed support.

With board discharging device (without board discharging)

Palm shaft diameter Φ180mm.

The material is 42CrMo, hard chrome plated.

Size: 280x160x10 (outer diameter x inner diameter X Thickness)

Haystack main motor power: DC 55kw

7.Vertical scrap Side Winder (two)

Uses: collect slitting machine cut sheet scrap edge.

Structure: composed of winding reel, rack and transmission system.

Foraging machine reel mechanical sizing for easy unloading.

Foreground winding machine with cloth device, evenly wrapped silk.

The foreground roll is driven by an AC motor, and the speed and winding torque are adjustable.

8, 2 pendulum bridge (Looper)

Structure see 1 swing bridge.

9, pr-separation device, tensioner

Uses: the slitting after the separation of the Strip, to prevent the overlapped material through the tensioner, easy to collect.

Structure: there are two sets of separation disc, a set of walking material height and contour, a set of less than walking material 200mm, the separation shaft can be operated out of the side, easy to replace the separation disc.

Foreground two sets of separation discs with anti-jump between the pressure roller, cylinder lift.

Tensioning machine uses: tension machine is applied to the slats positive pressure to produce winding tension, easy to tighten the sheet.

Structure: plate type tensioner.

The foreground slider is lifted by a cylinder.

The width of the foreground is arranged in segments.Presser foot with tooth pattern, felt easy to insert tight and easy to clean replacement.

10.Steering roller set and feeding plate

The feeding side of the feeding roller is arranged in the feeding roller, and the shaft end of the drum is provided with a speed measuring encoder of the winding machine.

The steering roller surface is made of Chrome.

Feeding pallet with feeding head on the feeding side of the feeding roller for easy feeding to the nices of the winder.

The feeding pallet is lifted and lowered by a cylinder.

11.Rewinding machine

Application: rewinding the slitting material.

Structure: single cantilever type.By The Drum, base, pusher plate, sub-material pressure head and transmission system and other components.

The foreground roll is a seamless roll, and the hydraulic cylinder pushes the wedge to drive the roll up and down.Shrinkage range Φ480-508mm.

The foreground roll is driven by an AC motor through a three-stage gearbox.

Automatic adaptation of harvest roll speed with slitting machine running speed.

Clutches with brakes.

The support shaft is made of 45cr.

The foreground is equipped with a classifying Binder, and the binder arm is swung by a cylinder.The pressing shaft can be manually swung around the fixed fulcrum to facilitate the replacement of the isolation plate (pad).

With a pusher plate, the pusher plate is pushed by a cylinder.

Foreground main motor power 75 kw, 900rpm

12. Discharging trolley

Use: remove the roll material from the winding machine after the removal of the drum.

Structure: the structure of the unloading trolley is basically the same as that of the loading trolley.

Forked trolley with anti-inverted plungers.
