5.The working principle and operation method of main components

Unwinding and feeding instructions

1). The unwinding and paper feeding system is composed of unwinding shaft, paper receiving table, brake roller and brake. The tension of the unwinding shaft is controlled by the automatic tension control system, so that the roll paper maintains the same tension from large to small. When the two rolls of paper are connected, put down the two pressure strips on the paper receiving table to press the paper, use a blade to cut the two ends of the paper and connect them with tape. After the paper is connected, lift the pressure strips.

2). Brake roller: It plays a very important role in maintaining constant tension when the roll paper enters the printing area. The size of the constant tension setting is appropriately adjusted by the thickness, thinness, width, and narrowness of the paper. The tension should not be too large or Too small, otherwise it will affect the accuracy of overprinting.

6.Printing overprinting system description

1. Make preparations in advance before printing, wear the material according to the picture (5) of the paper feed, first select the number of the anilox rollers according to the number of print patterns, then install the anilox rollers, install the printing rollers, and press Hold the paper, the pressure on both sides should be even, the pressure should not be too big, and then shake the pattern roller to leave a gap of 3~5mm away from the printing plate
2. Turn on the ink roller switch (the anilox switch is turned to “OFF”), pour in the ink, and put the squeegee. After the preparations are completed, you can start working.
3. Turn on the main motor switch, adjust the speed to about 4 m/min, and then turn the anilox roller switch to “on”, at this time the anilox roller will be raised by about 2mm, and then the anilox roller will be connected to the printing roller by shaking it. The pressure can not be too high, and then adjust the pressure of the printing roller and the printing paper, the same pressure can not be too large, otherwise it will affect the printing quality.

7.Receiving system description

1. Rewinding tension is controlled by automatic tension controller
2. Roll the material on the paper tube before printing, set the tension value, and turn on the automatic mode to rewind
3. In the process of normal paper feeding, the controller is in automatic mode, and the paper breaks. At this time, the tension value tested by the tension sensor does not reach the set tension value, the current will increase immediately, and the clutch or brake will always be activated. Locking, as in this case, first switch the automatic mode to manual mode, reduce the current, connect the paper, and switch to automatic mode again after turning on the machine.

8.Electrical panel switch description

3.Anilox roll off and on switch: Turn the switch to “on” before printing, and switch to “off” before the paper is changed and stop, so that the printing roller will go for 2-3 weeks (the ink on the printing roller is printed, Do not freeze the ink on the printing roller), and then turn off the main motor switch.

4.Switch and potentiometer adjustment for unwinding constant tension control: the unwinding paper is controlled by a magnetic powder brake, and the adjustment tension is appropriately adjusted by the thickness, thinness, width, and narrowness of the paper, so that the paper can be properly tensioned without excessive tension. Big or too small. (The current is set at about 0.35 ampere)

5.Unwinding automatic tension controller (installed on the right side of the first printing group), the controller has manual mode, automatic mode and potentiometer to set the tension value. When the machine is normal, please set the tension control in the automatic mode, adjust the tension from the paper thickness, thin, wide, and narrow to properly adjust the potentiometer (the tension value is basically set at about 60 Newtons)

6.Rewinding automatic tension controller (installed on the side of the rewinding shaft), the controller has manual mode, automatic mode and tension value plus △, minus ▽. When the machine is working normally, please set the tension control in the automatic mode. Pay attention to adjusting the tension size: adjust the tension value appropriately by the thickness and width of the paper. Control button: plus △, minus ▽.

7.Four sets of infrared heating drying switches and temperature regulators: the heating switch is turned on, and the drying heating temperature setting: adjust the temperature appropriately by the printing speed

8.Four sets of ink roller switches: the ink roller switch is turned on when the host is turned on. When the machine is stopped to change paper, the ink roller will automatically run after the anilox roller is separated. Otherwise, the ink roller will not rotate after the anilox roller is separated, which will freeze the ink on the anilox roller and damage the anilox roller.

9.Emergency stop and jog button: press this button to stop the host or press this button when it stops to make the host click in.

1, paper skewed

Possible reasons:

(1), lose on both sides of the paper support block imbalance.Requirements on the feeding table and highly consistent paper pile surface and relative paper heap center symmetric.

(2), on the feed conveyor belt and paper position is wrong, lose tape tightness is differ, etc all can cause the paper to skew, check the above exclude them one by one.

2, the paper appear double or more card or paper

Possible reasons:

(1), paper adhesion.Printing, stationery, coated paper, paper cutting hair, static, wet adhesion, easy to cause paper, therefore, must be in front of the die cutting on the paper.

(2), paper knife block and lose tape between the gap is too big, or too small may cause out of paper

3, the o ring groove pulley wheel and lost tape between the abnormal pressure

Possible reasons:

(1), Geneva wheel pressure wheel and the paper tape of abnormal pressure.

Second, the paper feed part

1, paper about inequality:

Possible reasons:

Walk about paper chain caused by asymmetric, can adjust the feeding chain up tight round position.

2, paper, upper and lower arch:

Possible reasons:

(1) may be paper pressure bar and walk paper nylon guide clearance between abnormal.

Part three, glue

1, glue points:

Possible reasons:

(1), the gel point is too big or too small, will affect the quality of molding glue.

(2), glue too little or too much of a roller, and also affects the quality of molding glue:

2, the location of the lugs and the tire

abnormal:

This is mainly because when check no paper sent to 500 mm, cylinder automatic contraction, the lugs and the release of a roller, and then if still no release of the lugs and play roller, and adjustable screw, make it to the appropriate location.

Four, molding parts

1, abnormal shape:

Possible reasons: all kinds of paper forming associated with mold.

Part five, the discharging

1, the abnormal discharge:

Possible reasons: the discharging gap between cage in stainless steel and paper box, can adjust the handle.
