The suction system on the front edge of the feeder prevents the surface of sensitive substrates from being scratched when feeding, suitable for printing electrostatic or easily scratched substrates such as thin sheets and films even for multicolor printing, the surface of substrates will have no scratches.
Open stacking board can be lifted or lowered as a whole. Aligned papers just can be directly pushed in when feeding, convenient and time-saving.
The optoelectronic double sheet detector does not touch substrates during detection, so as to avoid scratching them.
The feeder is equipped with anti-static device (plasma tuyere) to make it easier for the separation of substrates and for the delivery of sheet substrates. The feed board and delivery board can be added with anti-static bar.
Plasma tuyere is used to eliminate static electricity on the surface of substrates.
When substrates arrive at the location of the front and side lays, automatic registration is completed by the CNC sensor. If there is any tiny misplacement or substrate running, the screen printing machine will stop working automatically to ensure high accuracy of overprint and reduce reject ratio.
The surface of the delivery board is fitted with rice grain stainless steel plate that can reduce 30%~70% friction force between the substrate and the board surface to reduce surface abrasion. Meanwhile, controllable absorption device is used to fit for multiple materials.
The lifting and lowering of the squeegee system are controlled by cams and the pneumatic pressure kept device is fitted to ensure uniform printing pressure so that both spot and coat can be accurately printed out.
The substrate delivery system can ensure smooth delivery of printing part output and of subsequent drying part input. The delivery board can be folded down to facilitate to clean the screen, mount and dismount the squeegee and flood bar.
The weight of the printing cylinder is reduced by 28% while the strength and precision are higher. The vibration during operation is also lowered and the stability improved, which effectively prolongs the machine's service life.
PLC system is employed to centrally control the operation of the whole machine, supporting touch screen/button dual operating system and with automatic fault diagnosis and real-time display functions. It is easy to operate and improves the reliability and stability of equipment operation.
Suction nozzle device, each suction head is under independent control.
The screen frame can be pulled out, both facilitating substrate register or feeding adjustment and making it safer and faster to clean the cylinder and screen.
Ink dropping pan to prevent ink from dropping.
