Device for folding tissue paper of tissue paper making machine

Abstract

The invention discloses a device for folding tissue paper of a tissue paper making machine. The inner side of a punching belt one side of which is provided with a plurality of rows of holes is provided with a supporting plate, a standing plate is fixed on the edge of an upper baffle plate close to the middle and gradually forms an angle of 5-80 DEG with a plane from the back to the front, the upper baffle plate and a lower baffle plate are respectively arranged on respective adjusting plate devices at two sides of a stand, the lower baffle plate is positioned on the punching belt at one hole-free side, the lower baffle plate inclines for 4-8 DEG towards one hole side; the part of the lower baffle plate behind a projection joint of overlooking the upper and the lower baffle plates gradually raises, and the part of the lower baffle plate before the projection joint gradually reduces; the upper baffle plate is positioned on the punching belt at one hole side, the part of the upper baffle plate behind the protection joint gradually reduces, and the part of the upper baffle plate before the projection joint firstly raises and then reduces; and the projection joint is at a 25-35mm distance of the right end face of a second roll, and respectively at 10mm of two sides of the cross section of the center shaft of the second roll vertical to the plane. The invention is smooth in folding without blocking the tissue paper; and the folded tissue paper is smooth and has no wrinkles.

Description

technical field [0001] The invention relates to a paper folding device, in particular to a paper folding device for a napkin machine. Background technique [0002] The folding technology of general paper, especially hard paper such as A4 paper or kraft paper, is very mature and reliable. There are usually two methods: one is to block one end of the paper to make the paper bend and deform, and then press the deformed part with a pair of rollers. Fold well; the other is to use the upper and lower boards, which are mainly used for folding rigid envelopes at present, and only a small part of the envelope is folded. I have not seen folding soft paper or large area paper. According to the soft characteristics of napkin paper, the present invention improves the second method, so that it can be used to fold soft paper, and the origami area can be large or small, so that the folding process is smooth, there is no jamming, and the folded paper is very straight. No creases. Contents...
