Turnover paper folding mechanism

Abstract

The invention provides an overturning paper folding mechanism which comprises a rack, and a paper separating part, a paper taking part, an overturning part and a conveying part are sequentially arranged on the rack in the moving direction of extraction paper. The overturning part comprises an overturning frame, the two ends of the overturning frame are connected with a first power device for driving the overturning frame to overturn, a first rotating shaft and a second rotating shaft which are parallel to each other are arranged on the overturning frame, a half-folded plate is arranged on the first rotating shaft, a shifting piece is arranged on the second rotating shaft, and the half-folded plate and the shifting piece are arranged in parallel; the two ends of the first rotating shaft are connected with third power devices for driving the first rotating shaft to rotate in a reciprocating mode, the second rotating shaft is connected with a sixth power device for driving the second rotating shaft to rotate, and the horizontal position of the shifting piece is lower than the horizontal position of the half-folded plate. An additional inward folding device is not needed, the structure is simpler, and the cost is lower.

Description

technical field [0001] The invention relates to the field of paper-drawing production, in particular to an overturning origami mechanism. Background technique [0002] In order not to waste the expensive toilet paper, people divide it into square or rectangular shapes, stack them on top of each other, and then put them into a cardboard box with a small opening. Therefore, the top layer of the drawing paper (near the opening of the carton) will be folded for the first time to be taken out smoothly. After the drawing paper is stacked, the first layer of drawing paper will be folded in half. [0003] In the prior art, the half-folds for paper extraction are all upward folds, that is, outward folding, which is easy to operate. However, the outward folding method will cause the paper to be pulled outwards to be a single layer during initial use, which makes it difficult to pull outwards. , easily damaged, etc. Therefore, the paper is not easily damaged when the inner folding is...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the half-fold of the paper is folded upwards, that is, outward folded, which is easy to operate, but the outward folded method will cause the paper to be drawn outward during the initial use to be a single layer, making it difficult to draw outwards , fragile and other issues

Therefore, inward folding is less likely to damage the paper when it is pulled out than outward folding, but the inward folding device in the prior art is additional and needs to be performed before the paper is drawn and cut, which reduces the production efficiency of the drawn paper, and The existing inward folding device has complex structure and high cost
