The couch roll is positioned right above the cylinder mould main body, and the axes of the couch roll and the cylinder mould main body are parallel;

And the paper-forming blanket is clamped between the couch roll and the cylinder mould main body.

preferably, the waterproof and pulp-proof belt is a negative-pressure cylinder mould, and two ends of the cylinder mould main body are respectively provided with a circle of U-shaped waterproof groove; the waterproof end cover is also provided with a circle of U-shaped waterproof groove; the U-shaped waterproof groove on the waterproof end cover is tightly buckled on the U-shaped waterproof groove of the cylinder mould main body through the sealing strip, so that connection is realized.

More preferably, waterproof thick liquid prevention area negative pressure cylinder mould still includes:

one side surface of the net groove is arc-shaped and is matched with the radian of the surface of the net cage main body; the arc-shaped side surface of the mesh groove is close to the arc-shaped surface of the mesh cage main body, and the prepared mica is uniformly coated on the surface of the mesh cage main body through the side surface.

more preferably, the waterproof thick liquid of preventing takes the negative pressure cylinder mould, the cylinder mould main part is installed on the cylinder mould seat through the cylinder mould bearing at both ends.

the couch roll stand column is vertically fixed on the net cage seat;

The couch roll beam is horizontally connected to the couch roll upright post; wherein the couch roll is fixed below the couch roll beam.

More preferably, waterproof thick liquid prevention area negative pressure cylinder mould, the even interval distribution of above-mentioned air exhauster, the air exhauster is the axial compressor air exhauster.

the utility model discloses at least, include following beneficial effect: the utility model discloses simple structure, under the convulsions effect, form the negative pressure down in the sealed space, under the negative pressure effect, the speed that mica thick liquid sees through the cylinder mould increases soon, and the mica thick liquid of coating on the cylinder mould is accelerated to a certain extent under the effect of air exhauster, and meanwhile, the blank forming speed also accelerates on the woollen blanket, and output improves in the mica paper unit interval.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Drawings

Fig. 1 is the structure schematic diagram of the utility model discloses waterproof thick liquid of preventing takes negative pressure cylinder mould.

Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

as shown in fig. 1, the utility model provides a waterproof thick liquid of preventing takes negative pressure cylinder mould, include:

The cylinder mould main body 1 is horizontally arranged and cylindrical and rotates along the main shaft thereof; the net cage main body 1 is arranged on a net cage seat 10 through net cage bearings 9 at two ends; the two waterproof end covers 2 are sleeved on the main shaft of the cylinder mould main body 1 through end cover bearings 7 and are sealed at two ends of the cylinder mould main body 1; a plurality of exhaust fans 3 are respectively arranged on the two waterproof end covers 2 to extract the air in the net cage main body 1;

the couch roll 4 is positioned right above the cylinder mould main body 1, and the axes of the couch roll and the cylinder mould main body are parallel;

A paper-forming felt (not shown) is sandwiched between the couch roll 4 and the cylinder mould body 1.

One side surface of the mesh groove 5 is arc-shaped and is matched with the radian of the surface of the mesh cage main body 1; the arc-shaped side face of the mesh groove 5 is close to the arc-shaped surface of the mesh cage main body 1, and the prepared mica is uniformly coated on the surface of the mesh cage main body 1 from the inside of the mesh groove through the side face.
