Description

Traceless drying net for papermaking

Technical Field

The utility model relates to the technical field of drying nets, in particular to a traceless drying net for papermaking.

Background

The drying net for papermaking is an indispensable dewatering device for papermaking enterprises, is applied to the drying part of a papermaking machine, and plays a role in supporting and transferring paper sheets. With the rapid development of the paper industry and the improvement of the paper quality requirement, the paper industry has higher and higher quality requirement on the drying wire for paper making.

The contact area of the structure of current paper grade (stock) drying screen is most less with the paper, and then carries out the in-process of drying at the paper, because of moisture scatters and disappears, easily causes the trace on the paper, simultaneously because the structure bearing effect of traditional drying screen is relatively poor, simultaneously ageing-resistant effect is relatively poor, and life is shorter.

Therefore, there is a need to provide a traceless dryer wire for papermaking that solves the above problems.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model aims to provide a traceless drying net for papermaking, which aims to solve the problems that the existing drying net for papermaking, which is proposed in the background art, is easy to leave marks on paper and has short service life.

(II) technical scheme

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a no trace drying net for papermaking, includes and nets the net body, it interweaves by warp and weft to net the body and constitutes, and two adjacent warp misplace from top to bottom and distribute, the cross section of warp is the rectangle, the cross section of weft is circular, warp is 23 with the ratio of weft quantity: 13.

preferably, the ratio of the length of the weft yarn on the front side of the drying net body to the length of the weft yarn on the back side of the drying net body is 5: 3.

preferably, the length of the warp yarn cross section is 0.58mm, and the width of the warp yarn cross section is 0.37 mm.

Preferably, the cross-sectional diameter of the weft is 0.58 mm.

Preferably, the weaving density of the warp threads is 23 threads per centimeter, and the weaving density of the weft threads is 13 threads per centimeter.

Preferably, the warps and the wefts are made of PET materials.

(III) advantageous effects

Compared with the prior art, the utility model provides a traceless drying net for papermaking, which has the following beneficial effects:

1. according to the traceless drying net for papermaking, the weft is arranged on the front face of the drying net body, the length is long, the contact area between the monofilament and paper is increased, and meanwhile, under the action of the fine warp and weft, the contact position between the paper and the drying net body is not easy to generate net marks, so that the problem that marks are easy to leave on the paper is solved.

2. This no trace drying screen for papermaking through setting up the warp of high density and dislocation from top to bottom, improves its bearing effect, reduces the influence to the gas permeability simultaneously, adopts the PET material to make it have better dimensional stability and ageing resistance, has solved the shorter problem of life.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a traceless drying wire for papermaking comprises a drying wire body, and is characterized in that: the drying net body is formed by interweaving warps 1-8 and wefts 11-14, and the ratio of the length of the wefts on the front side of the drying net body to the length of the wefts on the back side of the drying net body is 5: 3, two adjacent warp misplace from top to bottom and distribute, the cross section of warp is the rectangle, the length of warp cross section is 0.58mm, the width of warp cross section is 0.37mm, the cross section of weft is circular, the cross section diameter of weft is 0.58mm, the warp is 23 with the ratio of weft quantity: 13, the weaving density of warp is 23 per centimetre, the weaving density of weft is 13 per centimetre, warp and weft are the PET material.

The working principle is as follows: the weaving rule is as shown in fig. 1, when the paper is dried, under the action of the finer warps and wefts, the paper is not easy to generate net marks, and simultaneously, the ratio of the length of the wefts on the front side of the dry net body to the length of the wefts on the back side of the dry net body is 5: 3, make it further improve the area of contact of monofilament and paper, ensure simultaneously and dry the gas permeability of net body, improve paper drying efficiency, adopt the PET material, make dry the net body and have better dimensional stability, improve its ageing-resistant effect, improve its bearing effect simultaneously under comparatively intensive and warp's from top to bottom dislocation effect, reduce the influence to the gas permeability simultaneously, improve its life.

It should be noted that, in the present specification, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
