5. Total Power: 14 KW

II. General structure requirements

1. Automatic cup-delivering
The cups will be delivered to the channel by the cup-serving-tray automatically, which could reduce labor intensity. The cup-delivering channel will be powered by electronic engineering sharing the same speed with pressing.

2. Principal machine and transmission equipments
Founding stand for machine is steadily reliable, and there is a complete adjusting system with X and Y coordinate system. Principal machine is powered by the frequency conversion electronic engineering, and in-phase with the speed of the delivering channel. There is also an automatic mode-switch device for the easy using of these two pressing mode.

3. Pre-printing Treatment
Corona treating is applied before printing. Processor axis is driven by rubber wheel which is driven by electronic machine, ensuring precise pressure.
When cups penetrated through, processor will give an alarm, in order to deal with it timely, preventing damage from the machine.

4. Printing
Printing stand is driven by machine; ink feeding volume can be easily adjusted.
Printing roller is equipped by fixing linchpin beard by spring for the purpose of changing printing plate quickly.
Printing platen is equipped with 3 rubber printing stands, adopting double-face glue and auto-stop when double or no cups.
QC checkpoint is adopted.

5. Axis (station) UV desiccation
UV light is 3KW, equipped with specially made glisten cover, cooling system and ozone venting system.
Light is auto out when machine stops or no cup in machine.

6. Auto cup ejecting
Speed of cup ejecting accords to speed of printing, avoiding wrong counting.
Counting wheel is adopted based on the height of cup, avoiding
Mistakes
Pneumatic device is applied to eject cups.
Cup incept plate angle can be changed, maximum cup ejecting distance is 800mm.

7. Electric control
The whole machine is controlled by low voltage appliance, all appliances in one control tank, with suitable height.
Control plate is a base, can be placed anywhere by controlled. Machine parts are connected by movable plugs, convenient for disassembling and maintenance.
