Analysis and Elimination of the Folding Part of the Printing Machine

Aug. 10, 2019

The common faults displayed by the folding department are blocked, which causes many reasons. Sheet Board Pasting Machine Supplier believes that the main points are as follows:

(1) The rubber strip on the folding cylinder is used for a long time or aging, which causes the rubber strip to lose its elasticity or the slit is too wide and too deep, which causes the newspaper to be cut continuously. Several newspapers are easy to be blocked at the flower wheel. The problem can be solved by replacing the new rubber strip.

(2) The cutter on the cutting drum is worn or the height of the cutter is not in place during installation, which causes the cutter to cut the newspaper and cause the newspaper to be blocked at high speed. The treatment method generally involves raising the knife holder, that is, adding a knife pad under the knife holder.

(3) Carton Box Printing Machine's pin, folding knife, the biting knife is seriously worn, or its corresponding cam roller bearing is stuck, or its corresponding torsion spring is broken, which will cause the folding to be in place and cause a blockage. The fault can be resolved by carefully checking these parts and adjusting or replacing the corresponding parts as appropriate.

(4) The cutting knife just cuts the adhesive tape for automatic paper picking and fails to cut it to cause clogging. This phenomenon is generally rare and there is no suitable treatment.

(5) The paper itself is too wet or the water is too large, which makes it difficult to cut and cause the blockage when cutting. If the paper itself is too wet, replace the paper roll; if the water is too big, turn off the small amount of water in time.

(6) The adjustment of the diameter of the folding roller of the High Precision Printing Machine is not appropriate or the tension before entering the folding section is improperly adjusted, which may cause blockage when the newspaper or the pinhole is pulled continuously. The treatment method is to check whether the folding roller diameter adjustment is appropriate and adjust as appropriate: check whether the shift roller tension adjustment is appropriate and whether the platen roller on the shift roller is too tight or too loose is solved.
