The lift of the platform adopts frequency conversion, and the left and right movement of the printing head use servo electric drive

1. Print head adopts Inverter motor, the left and right movements of adopt servo motor, and the material positioning adopts CCD optical lens +  Movable platform +industrial computer to ensure precise positioning.

2. Adopt the pneumatic control system for  printing blade rotates, to achieve the anti-dripping effect, and the structure is compact, convenient and practical.

3. Manual/Semi-auto/Full Auto Model can be set,Printing Time adopt digital control

4. The independently designed system for  head lifting device, squeegee/returning knife to make  frame loading&unloading and cleaning more convenient.

5. The Frame is fixed by pneumatically/mechanically , and distance can be adjusted. Also the X and Y axes are independently adjusted.

6. Discharge and reclaim material controlled by Servo motor , which will run stable and the positioning is accurate.

7. Optional with static elimination and dust removal device, easy to operate and more efficient.

8. Adopt Large-size LCD display , easy operate.

9. Can be connect with the Powder coating machine,  UV curing machine or IR drying tunnel to make the printing full-automatic. The design as follow

Machine maintenance

①   Clean the sundries on the machine and wipe it clean before going to work.The guide rail, guide column, bearing and other moving parts should be lubricated regularly.

② The work piece table is the key part which affects the printing quality, prevents the hard object to hit, when printing, cannot turn the ink.The water and other organic solvents drip onto the work surface.

③  Electric control panel and keys to prevent direct or indirect contact with water, water and other solvents caused by damage.

④   Frame paint is to keep the machine rust, to prevent days of water, water and other solvents directly or indirectly contact damage.

⑤  The sewage and dirt in the oil mist assembly should be discharged in time.Prevent feeding into pneumatic components, affecting normal operation, and regularly clean the cup body, add peng 2 lubricating oil in the oil cup of oil mist assembler.

⑥  When adjusting the limit valve, the tight nut must be unscrewed before hand adjustment.Handle screw on the machine is used for positioning, after firm positioning, no need to tighten it too hard.

⑦ After work, turn off the power/air source, clean the screen, and keep it properly.
