Technical Field

The invention relates to production equipment, in particular to an inclined wire former structure for producing special paper by using chemical fibers and inorganic fibers as raw materials.

Background

At present, the structure of the domestic oblique net former mainly comprises two parts of an independent oblique net head box and an independent oblique net forming box, and the angle between the oblique net part forming box and the horizontal direction is alpha. Because of the special requirements of some paper products or the requirement that the paper machine is suitable for producing various kinds of paper, the alpha angle can be adjusted and changed according to the process requirements, and the alpha angle and two side plates of the inclined wire flow box have a one-to-one correspondence relationship, when the alpha angle of the inclined wire is required to be adjusted, the two side plates of the inclined wire flow box need to be correspondingly replaced, or a fulcrum is also designed for the inclined wire flow box to be correspondingly adjusted at the same time, and the adjustment of the fulcrum and the two cannot be synchronous, so the adjustment process is very complicated and the cost is high.

Disclosure of Invention

In order to solve the problems, the invention provides a structure of an inclined wire former capable of integrally achieving stepless angle adjustment.

In order to achieve the aim, the inclined wire former structure comprises an inclined wire pulp flowing box, a forming box and a cross beam, wherein the forming box is arranged at the lower part of the inclined wire pulp flowing box and is fixed on the cross beam; one side of the inclined wire flow box is provided with a pulp inlet which is connected with a pulp inlet pipe through a hose, the lower part of the inclined wire flow box is provided with a lower lip plate, the lower lip plate is attached to a forming box panel through lip cloth, and two side wall plates of the inclined wire flow box, the forming box panel and the lower lip plate of the inclined wire flow box form a weir pool; the forming box panel and the horizontal plane form an angle alpha. The structure is characterized in that the inclined-wire pulp flowing box and the forming box are both fixed on the cross beam, and the angles between the inclined-wire pulp flowing box and the forming box and the horizontal plane are integrally controlled through the movement of the cross beam.

In order to achieve the effect of accurately controlling the alpha angle, the stepless lifting mechanism is an electric screw rod lifter, and the top end of the stepless lifting mechanism is connected with the cross beam through a hinge point.

In order to solve the problem of screen changing, the cross beam is provided with a screen changing cantilever which is connected with the operation side of the inclined wire pulp flowing box through a shaft block, so that the inclined wire pulp flowing box can be supported through the matching of the shaft block and the screen changing cantilever when the screen is changed.

In order to further improve the forming effect, the inclined net head box is of an open structure or a closed structure, the alpha angle is 0-30 degrees, the effect of adapting to the production of various different papers is achieved, the pulp inlets are uniformly distributed along the cross web direction, so that the purpose of isobaric arrangement is achieved, the hoses are plastic hoses or rubber hoses, and the influence on the pulp inlet pipes and other equipment when the cross beam rotates is reduced.

Compared with the prior art, the invention has the advantages of simplified structure and advanced function, not only considers the problem of angle adjustment, but also further solves the problem of screen change after integrated structure, has wide applicability, is particularly suitable for narrow test paper machines, can meet the development of various new products, improves the working efficiency and reduces the cost.
