How to adjust the running position and inclination of the folding machine? Below is an introduction for everyone.
Firstly, push in the safety cam and check that the machine is functioning properly before proceeding with the following operations.
1. Stacking paper operation
Arrange a stack of paper to be loaded, and perform indentation treatment on thinner paper first; When stacking paper, lower the stacking table to the appropriate height.
Special reminder: The stacking operation directly affects the quality of the fold, so when stacking paper, it is required to ensure that the side and front edges are flush.
2. Adjustment of paper separation mechanism
When the paper pile rises to a certain height, it automatically stops (controlled by the height probe), and at this time, the paper separation nozzle is about 1mm higher than the paper pile. The paper separation mechanism can be adjusted up, down, back and forth according to the paper size. The air volume of the hair dryer should be adjusted to allow the print to float slightly under the suction wheel. The brush or steel plate on the separation mechanism is used to prevent the generation of double sheets during paper separation, and its adjustment is based on the standard of not producing double sheets and not causing paper to be messy.
3. Adjustment of suction wheels
The suction wheel suction is controlled by an electromagnetic valve, and its main function is to transport paper. The suction volume can be adjusted by the knob. Turning it clockwise will reduce the suction volume, and vice versa will increase the suction volume. The suction point of the suction wheel has three positions: front, middle, and rear. In general, the suction point is in the middle vertical position. The suction length of the suction wheel is controlled by the selection switch on the operation panel. The paper feeding speed is slow, and the suction time is longer. Conversely, the suction time is shorter.
4. Adjustment of dual controller
Fold the paper in half (twice the thickness of the folded paper) and place it under the controller's knurled screw. The fan-shaped blade is driven to push the micro switch. The solenoid valve loses power and the suction is cut off. If the paper feeding is not stopped, fine tune the knurled screw to stop it.
5. Adjustment of the paper feeding table
Release the star shaped knob, adjust the paper feeding rule with a ball plate to the size of the print format, and tighten the star shaped knob. Adjust the paper support steel strip according to the width of the print, so that the side of the print passes through the steel strip. The pressure paper balls on the ball plate are made of steel balls and plastic balls, which are used to coordinate with the paper feeding belt to ensure that the printed sheet enters the fence correctly along the side gauge.
In actual production, steel balls and plastic balls should be placed according to the properties of the paper. Generally, 1-2 steel balls are placed near the folding roller to facilitate paper alignment. If the paper is cut unevenly or the two sides of the mouth are not consistent, the knurled nut can be adjusted. In addition, rotate the star shaped handle and adjust the position of the paper to align the center of the folded paper with the center of the first folding knife.
