Abstract

The utility model relates to a multifunctional double-cylinder paper making machine with a circular mesh, which comprises a mesh section, a press section, a drying section and two pieces of wet felt. Two mesh grooves 11 14 in the mesh section are distributed in opposite directions. The two pieces of wet felt are overlapped and contacted with each other on the press section for binding the layers of wet paper sheets. One of the pieces of wet felt covers an upper press roll 21 and passes through a first drying cylinder 31 and a first mesh cage 12. The other of the pieces of wet felt covers a lower press roll 22 and passes through a second mesh cage 13. When the two pieces of wet felt respectively contact the mesh cages 12, 13, the running direction of one of the pieces of wet felt is opposite to the running direction of the other of the pieces of wet felt. Therefore, the main quality problem of the difference of the front and the back of double-face paper existing on a paper making machine with a circular mesh is thoroughly solved. One multifunctional double-cylinder paper making machine with a circular mesh can be divided into two single-cylinder single-mesh paper making machines to produce single-face paper with high efficiency and low cost.

Multi-functional twin-tub cylinder mould machine comprises with the lower part: have the wet end of two net grooves and cylinder mould, have the press section of upper press and lower press; Drying section with two band roller drying cylinders; Two felt and reeling-up stands that overlap contact at press section.Two net grooves oppositely distribute relatively, said two felts are wet felt, wherein one encase upper press and with first drying cylinder and the first cylinder mould cross-under, and another Zhang Ze encase lower press and with the second cylinder mould cross-under, the rotation direction when press section overlaps contact and finishes these two wet felts of l Water Paper page or leaf interlayer combination and contact with cylinder mould separately is opposite each other.

Like this because the traffic direction difference of two wet felts, the wire side (being filtering surface) that makes two-layer l Water Paper page or leaf the press section interlayer in conjunction with the time all sandwiched in the ply of paper, making the page two sides of producing at last all is felt side (being non-filtering surface).

The purpose of this utility model can also reach by following measure.

Also include the deflector roll later a kind of wet felt traffic coverage that is installed in from lower press to second cylinder mould.

Said two band roller drying cylinders are the carrying roller drying cylinder that roller is positioned at the drying cylinder below, are equipped with the wet felt traffic coverage from second cylinder mould to second couch roll a kind ofly can open the standby roller later that connects with second dryer roller after adjusting wet felt, making it break away from lower press.

At this moment, a machine can be divided into two machines uses with the manufacture order facial tissue.First cylinder mould, the major part of first drying cylinder and a single net single cylinder paper machine of No. 1 wet felt composition; In like manner, break away to open with lower press and to connect, and open the major part that No. 2 wet felts connecing and second drying cylinder, second cylinder mould are also formed a single net single cylinder paper machine with second dryer roller.

Preferably have two reeling-up stands that are respectively first drying cylinder and the second drying cylinder work.

In sum, the utility model has following advantage compared to existing technology: thoroughly solved the main Quality of positive and negative this cylinder mould machine of difference of page, thereby and can be divided into two machines increase substantially production efficiency, reduction single face paper with the manufacture order facial tissue production cost by a machine.Compact conformation, transmission are stable, easy to operate, almost need not to increase miscellaneous equipment, therefore, are particularly suitable for the technological transformation of old paper machine, and transform duration weak point, small investment, instant effect.
