Abstract

Provided is forming box of a paper mechine wet end comprising a forming box and a drive part supporting component which is used to support the forming box and a drive part which is used to drive the forming fabric into reciprocating motion. The drive part is installed on the drive part supporting component. A forming surface which inclines in an angle of 0-30 degree is arranged on the forming box. A wiping plate is arranged on the forming surface with intervals. Water absorption holes which are connected with the internal of the box body of the forming box are arranged on the forming surface between two wiping plates. The both ends of the forming surface between the adjacent two wiping plates are plugged by end plugs to form a vacuum between the two end plugs. The upper net of the utility model has a low concentration, the long fiber has a good dispersity and the makable fiber has a good length to 30mm at most. The dehydration performance of the paper machine and the evenness of the paper making are fine . The inclined angle of the wire part can be adjusted between 0-30 degree. The largest amount of the paper making can reach 300/m[2]. The inclined wire paper machine wet end combines the characteristics of the fourdrinier wire and the cylinder wire forming and is especially suitable for making special paper of long fiber.

Description

The forming box of oblique net paper machine wet end

Technical field

The utility model relates to a kind of wet end parts of paper machine, the particularly forming box of oblique net paper machine wet end.

Background technology

Speciality paper generally is meant at a certain particular characteristic and purposes, surcharge than higher paper kind.Speciality paper is broadly divided into traditional speciality paper and special speciality paper.Tradition speciality paper can be used for special packing, label, decoration and other printing purposes etc., and special speciality paper needs unique working ability and special technology manufacturing to form, and market capacity is less usually, and this series products often has its particular performances.Oblique net paper machine and many kinetic energy long mesh paper making machine are arranged in the production equipment of speciality paper.The production equipment of the present speciality paper of China mostly is long mesh paper making machine and cylinder mould machine greatly.The technical equipment of equipment is relatively poor, and sky hits the U means and falls behind, and is difficult to satisfy speciality paper product small lot, high-quality, flexible and changeable characteristics.

The utility model content

Technical problem to be solved in the utility model provides that a kind of online concentration is low, and the fibre length that can manufacture paper with pulp is longer, and dewatering is better, copies the forming box of the good oblique net paper machine wet end of the evenness of paper.The forming box compatibility of this oblique net paper machine wet end the characteristics that are shaped of fourdrinier wire, cylinder, long fiber speciality paper is particularly suitable for manufacturing paper with pulp.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:

The forming box of oblique net paper machine wet end is positioned at the rear side of head box parts, it is characterized in that described forming box parts comprise:

Forming box and

In order to being supported to the driver part supporting member of molding box, and

Drive the reciprocating driver part of forming net; Described driver part is installed on the driver part supporting member; On described forming box, have one and be inclined to 0-30 ° of forming face, on forming face, be furnished with Wiper blade at interval, on the forming face between two Wiper blades, be furnished with the suction hole that is communicated with the forming box box house, forming face two ends between adjacent two Wiper blades form vacuum with end face plug shutoff, the zone that makes it between the both ends of the surface plug; Described forming net is by described Wiper blade.

Owing to adopted design as above, the special equipment that the utility model is shaped applicable to special material, it has utilized the wet moulding principle of the wet production of paper, but the production product that is suitable for is different fully with plain paper, its main feature has: 1) be suitable for the moulding of multiple fibrous material, as natural fabric, synthetic fiber, inorfil (comprising glass fibre, ceramic fibre), metal fibre etc.; 2, be applicable to the production of multiple functional material.As filtration, heat insulation, the branch modified fibre etc. that insulate, forming box of the present utility model is the main production equipments of wet method non-woven material; 3) online concentration is low, long stapled good dispersion, and the fibre length that can manufacture paper with pulp is longer, is generally 8-10mm, the longest 30mm that reaches, paper machine dewatering is better, and the evenness of copying paper is good.The angle of inclination of wet end can be copied the paper maximum and quantitatively can reach 300g/m 0-30 ° range regulation ², this oblique net paper machine wet end compatibility the characteristics that are shaped of fourdrinier wire, cylinder, long fiber speciality paper is particularly suitable for manufacturing paper with pulp.

Description of drawings

Fig. 1 is the structural representation of shaping box described in the utility model.

Fig. 2 is a shaping box described in the utility model installation site schematic diagram.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the utility model.

Referring to Fig. 1 and Fig. 2, the forming box 2 of oblique net paper machine wet end comprises forming net 21, forming box 22, driver part supporting member 23, driver part, and driver part supporting member 23 is installed on the basis, and forming box 22 is bearing in driver part supporting member 23.

On forming box 22, have one and be inclined to 0-30 ° of forming surface 221, on forming surface 221, be furnished with Wiper blade 222 at interval, on the forming face 221 between two Wiper blades 222, vertically be furnished with the suction hole 223 that is communicated with forming box 22 box houses, forming surface 221 two ends between adjacent two Wiper blades 222 have the bleeding point 225 and the water discharge outlet 226 that are connected with the vavuum pump (not shown) with 224 shutoff of end face plug on forming box 22 casings.During vavuum pump work, can form vacuum in the zone between both ends of the surface plug 224; Water in the slurry is drawn onto in the casing of forming box 22, and is discharged by water discharge outlet 226.
