Description

Technical Field

[0001] The utility model relates to the technical field of flattening of folding machines, in particular to a flattening mechanism of an automatic folding machine. Background Art

[0002] The folding process is often used in printing production. It is necessary to piece together the pages in a specific way according to the corresponding positions to form a whole page. After printing, the paper is folded to reproduce the page sequence intended by the designer. However, as the number of times the paper is folded increases, the bulkiness of the paper after folding increases. If the paper is folded three times or more than three times using a folding machine, the bulkiness angle of the folded paper will gradually increase. The subsequent folding paper sorting process will increase difficulty and production efficiency will decrease. After the paper is flattened, it is necessary to sort and align the paper to facilitate subsequent processes.

[0003] After searching, the patent with announcement number CN214732979U discloses a flattening device for an automatic folding machine, which belongs to the technical field of folding machines. The flattening device for an automatic folding machine includes a paper feeding platform, the upper surface of the paper feeding platform is fixedly connected with a paper feeding belt, both sides of the upper surface of the paper feeding platform are provided with placement grooves, a support block is arranged inside the placement groove, an adjustment column is movably connected to the upper surface of the support block, the top of the outer surface of the adjustment column is fixedly connected with the support column, the outer surface of the support column is movably connected with a movable sleeve, one side of the movable sleeve is fixedly connected with a locking sleeve, the outer surface of the movable sleeve is movably connected with a pressure wheel, and one side of the support block is provided with a threaded hole. The flattening device for an automatic folding machine adjusts the height of the pressure wheel and the position on the paper feeding belt by screwing the clamping bolt and the fixing bolt, and the adjustment is more convenient, and the adjustment can be completed without using tools, saving time and effort.

[0004] The technical solution has the following problems:

[0005] Although the paper can be flattened by the pressure wheel, when adjusting the height of the pressure wheel, two clamping bolts need to be screwed in sequence to release the adjustment column, and the height of the pressure wheel can be adjusted only after the clamping bolts are tightened after adjusting the appropriate height, which is troublesome and inefficient.
