Abstract

The utility model discloses a multiple layer shaping net used for paper making, which comprising a surface net, a bottom net and a connecting net. Wherein, both a longitude density and a woof density of the surface net are larger than that of the bottom net; the surface net adopts a half-inclined net grain while the bottom adopts a four-port broken satin grain; the longitudes of the surface net are not connected with the woofs of the bottom net while the longitudes of the bottom net are not connected with the woofs of the surface net. The utility model is applied on the high speed paper machines and has the advantages of long using time, compact structure and high remaining rate of paper pulp fiber.

Description

The paper grade (stock) multi-ply forming fabric

Technical field

The utility model relates to the paper grade (stock) meshi fabric, especially relates to a kind of forming net that is applied in paper sheet formation on the paper machine.

Background technology

Existing forming net for papermaking is generally individual layer or two-layer, short, shortcoming such as the paper pulp fiber retention is low of life-span generally can appear in the individual layer forming net on high-speed paper machine, and two layers of mesh generally adopts warp to make to go up off line syndeton line, warp is crooked serious, structure is loose relatively, and graticule is shifted easily.ZL99241847.X discloses a kind of paper grade (stock) polyester composite web, and this net divides double-layer structure, but go up off line employing wear tie lines jump three or four warps, span is bigger, anastomose is made a concerted effort inadequately up and down, peels off easily.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of multi-ply forming fabric of using on the high-speed paper machine that life-span is long, structure is tight, the paper pulp fiber retention is high that is applicable to.

In order to achieve the above object, the utility model adopts following technical proposals: a kind of paper grade (stock) multi-ply forming fabric, comprise veil, spacer screen, binding net, the veil thread count is greater than the thread count of spacer screen, veil adopts half oblique reticulate pattern, spacer screen adopts four to combine broken satin weave, and described veil warp does not link the spacer screen parallel, and the spacer screen warp does not link the veil parallel.

This paper grade (stock) multi-ply forming fabric, veil adopt bigger through filling density, and it is more level and smooth both to have made into paper, can improve the paper pulp fiber retention again.Spacer screen adopts the parallel in big line footpath, makes forming net more wear-resisting on the paper machine, and the life-span is longer.Link net and adopt even parallel binding veil and spacer screen, it is less to link span, makes the structure of forming net tightr.

Fig. 2 is the cross-sectional structure schematic diagram of first embodiment of the utility model paper grade (stock) multi-ply forming fabric in the paper machine operation direction.

Fig. 3 is the cross-sectional structure schematic diagram of second embodiment of the utility model paper grade (stock) multi-ply forming fabric in the paper machine operation direction.

Fig. 4 is the cross section structure schematic diagram of second embodiment of the utility model paper grade (stock) multi-ply forming fabric in the paper machine operation direction.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 and Fig. 2 show the utility model multilayer first embodiment with forming net.Veil 1 adopts half oblique reticulate pattern, and spacer screen 2 adopts four to combine broken satin weaves, and veil warp 3 does not link spacer screen parallel 5, and spacer screen warp 6 does not link veil parallel 4.The circulation of warp is made up of eight veil warps 3 and four spacer screen warps 6, parallel circulation by 24 veil parallels 4 and 12 spacer screen parallels 5, four even latitude 7 form, face, end graticule are evenly distributed by the interval.Connect 12 warps in latitude 7 every intervals and be once circulation, after passing in six veil warps 3 and two spacer screen warp 6 centres, upwards press a veil warp 3, collude with 6 one of spacer screen warps downwards.

Fig. 3 and Fig. 4 show second embodiment of the utility model multilayer with forming net.This embodiment compares with first embodiment, veil 1 circulates identical with spacer screen 2 structures, warp and parallel, connect 12 warps in latitude 7 every intervals and be once circulation, after passing in the middle of two veil warps 3 and the spacer screen warp 6, collude with a spacer screen warp 6 downwards, after passing in the middle of three veil warps 3 and the spacer screen warp 6, upwards press a veil warp 3 then again.

The above is two embodiment of the present utility model, and some improvement of making for not breaking away from the utility model principle all are considered as protection domain of the present utility model.

Claims

1, a kind of paper grade (stock) multi-ply forming fabric comprises veil, spacer screen, binding net, and the veil thread count is greater than spacer screen. thread count, veil adopts half oblique reticulate pattern, spacer screen adopts four to combine broken satin weave, and it is characterized in that: the veil warp does not link the spacer screen parallel, and the spacer screen warp does not link the veil parallel.

2, paper grade (stock) multi-ply forming fabric according to claim 1, it is characterized in that: eight veil warps and four spacer screen warps are formed a warp circulation, article 24, veil parallel and 12 spacer screen parallels, four even parallel circulations of latitude composition, face, end graticule are by being evenly distributed at interval.

3, paper grade (stock) multi-ply forming fabric according to claim 2, it is characterized in that: connect 12 warps in the every interval of latitude and be once circulation, after passing in the middle of six veil warps and two the spacer screen warps, upwards press a veil warp, collude with one of spacer screen warp downwards.

4, paper grade (stock) multi-ply forming fabric according to claim 1 and 2, it is characterized in that: connect 12 warps in the every interval of latitude and be once circulation, after passing in the middle of two veil warps and the spacer screen warp, collude with a spacer screen warp downwards, after passing in the middle of three veil warps and the spacer screen warp, upwards press a veil warp then again.
