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 an evenly-knitted net grain while the bottom net adopts a four-port full-inclined net 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
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 the plain weave reticulate pattern, spacer screen adopts four to combine full twill, 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 adopts bigger 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.
Description of drawings
Fig. 1 is that first embodiment of the utility model paper grade (stock) multi-ply forming fabric is at paper machine operation direction cross section structure schematic diagram.
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 the plain weave reticulate pattern, and spacer screen 2 adopts four to combine full twill, 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 eight 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 16 warps in latitude 7 every intervals and be once circulation, after passing in the middle of three veil warps 3 and three the spacer screen warps 6, upwards press a veil warp 3, after passing in the middle of two veil warps 3 and two the spacer screen warps 6, collude with two spacer screen warps 6 then downwards again.
Fig. 3 and Fig. 4 show second embodiment of the utility model multilayer with forming net.This embodiment compares with first embodiment, and it is the same to connect latitude 7 trends, difference be a parallel circulation by 16 veil parallels 4 and eight spacer screen parallels 5, four even latitude 7 forms, face, end graticule are evenly distributed by the interval.
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.
