High-speed paper folding machine

Abstract

The invention discloses a high-speed paper folding machine. A paper blocking disc is arranged above the edge of the inner end of a paper stacking table, and the paper blocking disc and the paper stacking table are arranged in a mutually perpendicular mode; a paper sucking mechanism comprises a negative sucking roller; a control shaft is arranged in a machine frame; a plurality of air spraying holes are formed in the bottom of the paper blocking disc; a plurality of air sucking holes are formed in the negative sucking roller; an air blowing propeller is arranged between the paper blocking discand the negative sucking roller; air blowing holes are formed in the air blowing propeller; and a first control valve used for controlling the air sucking time of the air sucking holes, a second control valve used for controlling the air spraying time of the air spraying holes and a third control valve used for controlling the air blowing time of the air blowing holes are arranged on the control shaft. The high-speed paper folding machine has the advantages that paper on the lowest layer can be quickly and stably sucked into a paper feeding mechanism, the operation stroke is shortened, the first control valve, the second control valve and the third control valve on the control shaft guarantee that the air sucking holes, the air spraying holes and the air blowing holes work in order correspondingly, and therefore the paper is quickly and stably sucked into the paper feeding mechanism, and finally the working efficiency of the paper folding machine is improved.

Description

technical field [0001] The invention relates to a paper folding device, in particular to a high-speed folding machine. Background technique [0002] At present, in the process of automatic packaging of medicines, it is generally necessary to pack the folded instructions into the packaging box. Using an origami machine to fold the instructions is a necessary link in the automatic boxing process of medicines. In the automatic cartoning process, the folding speed of the paper folding machine should match the speed of the cartoning machine. With the continuous development of domestic cartoning machine technology, the packaging speed of the cartoning machine has gradually developed from the original 100 boxes / minute to 200 boxes / minute, 300 boxes / minute, 400 boxes / minute, and even 500 boxes / minute. However, the original origami machine has the defects of slow folding speed and prone to failure, such as paper suction failure, paper jam, air leakage and other problems. [0003] ...

Problems solved by technology

[0003] The Chinese patent is a utility model patent of 201720881786.1, which discloses a high-speed paper folding machine, which includes a frame and a stacking table for placing paper to be folded. In the frame, a paper separating mechanism, an air suction mechanism, Paper feeding mechanism and paper folding mechanism, paper separation mechanism includes blowing shaft, paper separation hook and blowing mechanism, used to separate the bottom sheet of paper to be folded from the upper layer of paper to be folded, suction mechanism includes suction shaft and fixed on the suction There are multiple hollow suction rockers on the air shaft, and the free end of the suction rocker is provided with a paper suction nozzle with an opening facing upwards for sucking the paper to be folded. The paper feeding mechanism is located below the paper suction nozzle for Feed the paper to be folded into the origami mechanism, which is used to fold the paper to be folded in half multiple times and output it out of the frame. Although the origami machine with this structure operates relatively stably, it can ensure that only one sheet of paper is fed at a time, the paper is separated, and the origami is performed. However, due to the complex and scattered mechanisms of the suction and paper separation mechanism and the suction mechanism, and the cooperation between the mechanism and the mechanism for a long time, how to ensure that the paper enters the paper feeding mechanism quickly and stably needs to be further improved
