Ⅰ.Unwind Parts

Double put scroll active put roll form;
Put scroll independent drive system adopts imported all-digital ac vector frequency conversion system;
PLC tension control and tension detection system and DANCER stable system, tension control stability; by KESAI-TKM-660E Company
Tension closed-loop control, can produce zero tension control, both low and high speed can have a stable output;
Swing roller tension detection participate in the closed-loop control, the feedback signal is issued by a linear potentiometer;
Linear type cutting knife can realize high speed without stopping the pros and cons of cutting, save time, improve efficiency;
Refueling stylish material spindle automatic drive and with the host with speed automatic cutting, refueling tension stable, reject rate is low;
Coil installation gassing shaft safety chuck clamping, change fast, safe and reliable;
Flip rack automatic flip to a transfer after automatic positioning, emergency head have reset
function;
Minimum volume diameter alarm device, can remind operator timely refueling, lest cause
the material waste.

Ⅱ.Infeed Part

Dual roll on-roll steel soft binding tension divisions segmented guaranteed;
Traction steel rollers driven by an independent motor synchronization arc toothed belt drive;
The traction tension servo motor control, better performance;
Soft roller clutch, pressure regulator pneumatic components;
PLC of the high sensitivity of the tension of the closed-loop control system; by KESAI
Swing roller tension detection participate in the closed-loop control.

Ⅲ.Printing uni

Independent servo motor control, can shorten the period of time greatly, reduce material loss, improve the printing precision; total setting waste:100-120meters
It adopts the form of shaft-less mounting plate, quick replacement, accurate positioning, with an initial pre-register system, which can quickly enter the register printing;
Pressure roller as a whole with a shaft for quick replacement;
Embossing roller under pressure structure of the swing arm, and the guide roller collaborative action to ensure that changes in the expected long under pressure / rising minimum Reduce the initial registering time, save material;
Combined pressure of the impression roller for a sequence of actions, stop at the same time the clutch. (Also based on the operating habits within the touch screen to change);
Scraper devices for pneumatic pressure, clutch, three-position adjustment structure, can create the best position angle;
The scraper movement is dual-axis movement, and is controlled by independent motors. Each group of scraper motors is controlled by an independent frequency converter, which does not affect the printing of the whole machine.
Trolley type ink tank, easy loading, and can effectively prevent the ink splash;
Adopts synchronous belt soft drive and pneumatic compression combination design, improve the transmission stability and reduce drive noise;
Adjust roller bilateral adjustable table headband indicator.
Distance between unit to unit 1500mm

Ⅳ.Dry unit

Independent monochrome group drying system design, a single set of automatic thermostat control, favorable colors printing; PID Temperature Control with Independent Motor
Bilateral back exhaust air from the outside to the inside, drying, no bubble phenomenon.
Using high pressure, high flow, low temperature drying, the maximum energy saving;
Fully enclosed oven, heat source can be secondary return air utilization;
The nozzle is a flat long air nozzle to ensure sufficient air pressure.

05.

Ⅴ.Cooling unit

Water cooling roll cooling method, the wrap angle of the water-cooled roller, the contact material length, the cooling effect is obvious;
Cooling water in the rollers within the full-roller body circulation, forced circulation;
The backwater is self-overflowing, no need for large water pressure, no rotary joint;
Roller body placed in the rolling bearing, small inertia, flexible.

Ⅶ.Rewinder unit

Tape frame, machine stability;
Two pairs of active Rewinding forms put the warp;
Winding independent transmission system adopts imported full digital AC vector control system;
PLC tension control and tension detection system and DANCER stable system, tension control stability;
Tension closed-loop control, can produce zero tension control, both low and high speed can have a stable output;
Swing roller tension detection participate in the closed-loop control, the feedback signal is issued by a linear potentiometer; Omron
Cutting knife can realize high speed without stopping the pros and cons of cutting, save time, improve efficiency;
