1 Security. In the description of almost all equipment in foreign countries, safety will be explained in the first part, which also reflects the people-oriented design idea. It also reminds our operators to pay attention to safety.
1.1 Safety Instructions
Warning: <Warning with rotating rollers, rollers or gear parts>!
The above symbol is to remind that when the expansion cover is opened, some parts of the machine are still rotating, and if the operating regulations are ignored, the person will be injured.
When working at the Feida, pay attention to the moving parts (suction nozzle transfer shaft, etc.). Special care should be taken in the transfer area.
2 Preset Feida, specifically the preset position of each part of Feida
2.1 Air volume control of the suction head
When the suction head valve is closed, the following data is displayed on the pressure gauge on the drive face:
·Standard blowing pressure
About +1.0 bar,
· Standard inspiratory pressure.
About -0.6 bar.
2.2 Front paper
If the front edge of the stack is drooping, you can open the front flap. Use the rotary knob to adjust the air volume.
2.3 paper blowing
The paper separation blower can be adjusted in the following positions:
·Feida stacks on both sides
·Feida paper pile front corner
· Feida paper pile rear edge.
Setting Options:
· Height: Adjust the embossing nut.
· Adjust the air volume of the valve.
Replace the paper separator
The round paper separator of the rear edge can be replaced with a box type hair dryer;
(1) Hold the hair dryer and unscrew the nut.
(2) Remove the blower.
(3) Insert the paper separator hair dryer: the locking notch needs to face upwards.
(4) Tighten and tighten the nut until the blower is adjusted to the desired height.
Set the amount of air blown:
The air volume of each blower can be adjusted separately by the control knob above the switch.
·Open the hair dryer before running the paper
·Operating surface corner / bevel blow
·Drive surface angle / bevel blow
2.4 Pressing paper feet
(1) Press the paper foot so that the mark on the top is embedded in the end of the support rod.
(2) Set the amount of blown air on the valve.
2.5 after the hair dryer
(1) Adjust the amount of air blown on the air valve.
(2) Adjust the height by adjusting the tightness of the pattern screw.
(3) According to the paper format adjustment: loosen the screws, remove the parts above the support frame, remove the hair dryer from the support rod.
(4) Rotate the blower to the appropriate position of the support rod, put the parts above the support frame back to the original position, and screw the screws.
2.6 paper blowing
(1) Use the adjustment nut to adjust the height of the paper feed blower.
(2) Adjust the direction of the blow so that the blow is just blown under the raised paper until the leading edge of the paper.
(3) Adjust the amount of blowing.
2.7 paper stack rear cover
Handling jams and different thicknesses of paper have different sizes of blanks:
· Jam
· Paper
The distance from the stack to the rear stop should be about 1 mm.
If you need to increase the pressure of the paper jam on the paper jam, just screw the pattern nut up.
The paper support is above the paper.
2.8 paper brush, paper jam and paper sheet
The separation brush/paper separation sheet prevents separation of the paper or simultaneously picks up two sheets of paper.
Paper brush/paper separator
• The paper separation sheet is inserted into the stack from 2 mm to 10 mm.
• Height: 1 to 3 mm directly above the edge of the paper.
▲Note
The separation of the separation nozzle to the stop can not be blocked.
2.9 paper nozzle
Set the paper separator in the press operation
The separation nozzle holds the rear edge of the top sheet of paper and lifts it up, separating it from the other sheets.
·Set the height:
Use the adjustment knob: The paper bounces slightly.
Adjust the tilt angle:
Use the adjustment knob: parallel to the stack.
▲Note
If you pick up two sheets of paper, raise the separation nozzle without reducing the amount of suction.
Depending on the printed material, the suction head is straight, slanted, curved and comes with different types of rubber suction cups.
2.10 Handing mouth
The paper feed nozzle sends out the paper picked up by the paper suction nozzle. The same suction cup can be used for the paper feed nozzle or for the paper suction nozzle.
▲Note
The delivery nozzle is only controlled by suction, so check its operation function frequently. Do not add oil or grease.
Adjust the gap of the paper feeder when the press stops.
(1) Loosen the socket head cap screws.
(2) Adjust the position of the delivery nozzle.
(3) Tighten the hexagon socket head cap screws.
Adjust the height of the paper feeder during operation of the press
Turn the control knob. When the paper suction nozzle is vertically down, the height of the paper should be about 5 mm.
