2. platen roller

1) the outer diameter of the embossing roller is ф156mm.
2) thick-walled seamless steel pipe with finely ground surface and hard chrome plating.
3) balance correction, smooth operation.
4) the adjustment gap of the pressure roller adopts a self-locking structure, and the adjustment range is 0-11mm.

3 ink transfer anilox roller

1) anilox roller diameter φ 214mm thick-walled seamless steel pipe surface is finely ground before surface grinding, engraving anilox, hard chromium plating
2) the dots are consistent, the ink is evenly spread, and the service life of the printing plate and the rubber roller is prolonged.
3) the speed difference between the rubber roller and the anilox roller can be formed to allow the rubber roller to perform the ink scraping function.
4) cooperate with the air feeding type automatic lifting device of the paper feeding system (the screen roller descends and contacts the printing plate when printing, and the screen roller rises and separates from the printing plate when printing stops)
Note: 200 line steel anilox roller in the first color, 220 line steel anilox roller in the second color, 250 mesh anilox rod in the third color, and 280 mesh steel anilox rod in the fourth color.

Place of origin: Dalian Junfeng

4 ink rubber roller

1 outer diameter rubber roller ф198 mm.
2 high-quality seamless steel pipe wrapped with durable, corrosion-resistant and wear-resistant rubber.
3 rubber roller special grinding high, good ink transfer effect.
4 the adjustment of the gap of the rubber roller adopts a self-locking structure, and the adjustment range is 0-3 mm.
Place of origin: Dongguang Xintai

5. phase adjustment mechanism ( inverter control )

1) planetary gear structure.
2) touch screen digital display phase indication makes operation more convenient, intuitive and accurate.
3) electric digital 360 ° adjustment of printing phase ( can be adjusted during running and stopping ).
4) the printing plate roller adopts electric adjustment phase. Zeroing and plate adjustment are fast, and plate adjustment accuracy is high. Each group of the whole machine and paper feeding are automatically reset to zero first, and then the phase is automatically adjusted coarsely, after the trial printing of one sheet, the digital fine adjustment is input to greatly reduce the waste of cardboard.

6. water and ink circulation structure

1) pneumatic diaphragm pump, stable ink supply, simple operation and maintenance. ( ink fountain made of stainless steel )
2) ink strainer to filter impurities. ( using Wuhan Changjiang brand one-way diaphragm pump )

7. printing phase fixing device

electromagnetic brake mechanism, when the unit is separated to adjust the phase, the brake mechanism limit the gear rotation to maintain the fixed point of the original tooth position.

C die-cutting department

1. operating function

1) the template roller and the Uli rubber roller are automatically disengaged by the cylinder eccentric device without die cutting. Reduce the no-load load of the machine, and at the same time extend the life of the urethane and die.
2) planetary gear type structure, the same as the printing department, grinding and cutting group plus an auxiliary motor, frequency conversion control, front and back synchronization, high die cutting force, which will not affect printing results.
3) the die cutting phase is adjusted by electric digital 360 ° (can be adjusted during running and stopping).
4) the machine is equipped with a urethane smoothing device, which can be used after repeated correction of the rubber roller.

2. knife mold stick
