Preheating adjusting area by electric: 360°
Diameter of the roller for Preheating adjusting area by electric:Φ85mm
3, Steam temperature: 150-200ºC Steam pressure: 0.8-1.3Mpa
4, Working Power: 380V 50Hz
5, Power:250W Short Time(S2) Working Type
4.Gluer
Structure and Features:
1, Glue rollers' surfaces are annealed, inside hold processed, with dynamic balanced.
The surface is grinded and carved reticulated mottles, glue balance and cost less
2, The glue rollers' turning is controlled by frequency variable motor& frequency variable controller. With frequency variable controller, the glue rollers' speed can follow the double facer or by himself.
3, To prove the nice glue water and do not waste, we adopts auto recycle glue supply, with glue amounts effective controlled, to avoid the glue to become sediment, auto track glue amount.
4, All the rollers surfaces are grinded then chromed plated.
5, Up & down level glue is driven by one frequency variable motor.
5.Conveying Bridge
The Main Frame is connected with channel steel, and angle steel.
2, With Protecting Handrail on both sides and safety pedal, the operation side is installed with safety ladder, to make sure the safety and convenience of the worker.
3, PVC feeder belt to transport the single or double face corrugated sheet with corrugated type.
4, Vacuum suction tension control, suction pipe(140mm) with adjusting valve,draw fan power can be adjusted freely.
5, Electric to correct the position of feeding( two sets),correct parts are driven byfast and accuracy to position, steady to move.
6.Double Facer
1, Hot Plates' surfaces is grinded and then chromed plated,width:600mm.total 9pieces of hot plates, cold shaping part:4m length.
Hot plates are made by container plates, can pass the national first level pressure container standards
2, Hot plates adopts the compressed gravity press rollers structure.
3, Press rollers' lifting up and down are driven by pneumatic structure.
4, Up convey belt left and right correct by auto with both sides, tension adjusting system:2 sets; downbelt manual small amount adjust.
5, Drive part,gear oil drown lubricating type.
6, Main drive motor: Variable frequency motor, high force when low speed start, high speed adjusting range, steady to use,easy to mend.
7.Electric Slitter Scorer
Structure and Features:
1, Adopt the scheduled pressure paper feeding which is stably.
2, Adopt thin knife separate cutting (The thickness is only 1 mm.). To make sure the separate-cut corrugated board smooth and tiny, we installed with automatic and hand grinding wheel grinding to keep the blade edge sharp.
3, After pre-pressing, separate cutting and creasing the paperboard to accomplish the requirement of the product. The pressed trace does not arouse the trace tearing phenomenon.
4, Thin Blades Slitting, Scorers creasing
8.NC Cut Off
Structure and Features:
1, Cutting length:500mm-9999mm.
2, Cutting precision:±1mm.
3, Uses the independent oil pump and the filter coordinates two groups of copper tubes to distribute in various gears position for the oil,the lubrication and cooling.
4, Helical knife structure,type sawtooth knife,decrease cutting obstruction,low noise.
5, Balance treatment:high quality alloy steel for blade shaft,which helps to keep it good stability.
6, Sun-shape wheels press cardboard in the front and the rear conveyer.The transporting is stable and with even pressure,which avoid jam caused or broken cardboard.
7, This type of Cut-off just consume the one of third energy compare with the common cutter with its especial structure,economize above 70% energy to get more money.
8, Exact and adjustable on gap gear assure knife-edge joggle exactly.running balanceable.
9,Computer system to keep order. Man-machine conversation system NC. automatic adjust cutting speed by cardboard specification and maching.The screen display various production message.Can consult,modification,superaddition and cancel order during running machine.
9. Stacker
Structure & Features:
1, Weld by 14 # channel steel, electric to adjust the size of the board, pneumatic to control the the output on transverse direction, output speed can be adjusted electrically.
2, Corrugated sheet can be controlled output by foot switch when the mount or height of stacking corrugated sheet reaching the needs.
10.Glue Making System
1, Supply the glue for the single facers and double glue machine which use glue water
2, The glue in the glue storage tank are transported by the glue pump to the device.
3, The storage tank and glue supply tank are with mix device, to avoid the glue becoming into the sediment.
4, Glue making device: Main Glue mixer, Vice Glue Mixer, Glue storage tank, glue feeding pump, glue return pump.
5, Glue making system adopts the recycle glue supplying, the rest glue returns back, the liquid level is auto controlled by floating ball, the glue from the return tank is transported to the tanks of each glue using device, to make the functions of the recycle and saving be true, and avoid the glue becoming into the sediment.
6, After the work finished, rest glue of each glue using devices are draw to the glue return storage tank to prepare for the next time using.
7, Responsible for technique guidance, and glue making way.
11.Steam System
Structure & Features:
1, To supply the heating energy for the various heating parts of the line, and keep the working temperature steady.
2, Each groups are deigned to be single steam supply system, temperature control by separately, energy saving and adjust conveniently.
3, Temperature controlled by adjusting the steam pressure, and with pressure gauge.
4, To long the using line of the rotary joints, the pipe system and rotary heating parts are connected by metal flexible pipe to realize the flexible connection
5, All the steam pipes are made of seamless steel pipe, to make sure the safety under the normal pressure.
