Description

Technical Field

[0001] The utility model relates to the technical field of papermaking, in particular to a former for a superforming papermaking machine. Background Art

[0002] In the field of papermaking, papermaking operations are generally carried out through superforming papermaking machines, among which the papermaking cylinder is the most important component of the superforming papermaking machine. Since the papermaking cylinder is a circle with a larger diameter, during the papermaking process, the pulp is sprayed onto the papermaking cylinder through a sizing device, and the moisture in the pulp is discharged through the mesh holes of the papermaking cylinder. The papermaking cylinder only contains a small amount of water and formed paper sheets. The wet paper is then stuck to the adsorption cloth through a rotating adsorption cloth for forming the paper. Since the size of the papermaking cylinder is larger, the formed paper is also larger.

[0003] In the prior art, when the wet paper is peeled off from the papermaking cylinder, since the pulp contains fine fibers, these fine fibers will get stuck on the holes on the cylinder and cannot be completely integrated into the paper. Therefore, pulp will remain on the papermaking cylinder. At the same time, since the paper is adhered to the adsorption cloth by adsorption force when it is peeled off from the papermaking cylinder, it is possible that the paper is not completely removed from the papermaking cylinder and will be adsorbed on the paper formed in the next circle as the papermaking cylinder rotates, thereby reducing the quality of the paper.

[0022] When a large amount of pulp is accumulated on the main laminating plate 4 and needs to be cleaned, the main laminating plate 4 can be rotated to drive the top corner of the auxiliary laminating plate 7 to fit the outer circle of the papermaking cylinder 1, thereby continuously cleaning the residual pulp on the papermaking cylinder 1.

[0023] like Figures 1 to 4 As shown, the ends of the main laminating plate 4 and the ends of the auxiliary laminating plate 7 are provided with holes 8 for the pulp waste to pass through.

[0024] The pulp remaining on the papermaking cylinder screen 1 can fall off through the perforations 8 .

[0025] like Figures 1 to 4As shown, a push rod 9 is fixedly installed at the end of the rotating rod 3, and a gripping rod 10 is fixedly installed at the end of the push rod 9 away from the rotating rod 3, and a positioning rod 11 is symmetrically fixedly installed at one end of the fixing frame 2 corresponding to the positions on both sides of the rotating rod 3, and a fixing rod 12 is fixedly installed at the end of the fixing frame 2 close to the positioning rod 11 at a position corresponding to the position below the rotating rod 3, and the fixing rod 12 is arranged between the two positioning rods 11, and a pulling spring 13 is fixedly installed between the gripping rod 10 and the fixing rod 12. The angle of rotation of the push rod 9 left between the two positioning rods 11 is the same as the rotatable angle between the main bonding plate 4 and the auxiliary bonding plate 7.

[0026] By rotating the gripping rod 10, the rotating rod 3 is driven to rotate, and the other side of the gripping rod 10 is brought into contact with another positioning rod 11. At this time, the angle of the pulling spring 13 will change, which is used to pull the gripping rod 10 close to the positioning rod 11 at this time, and is used to fix the position of the main bonding plate 4.
