Abstract
The utility model relates to the technical field of papermaking squeezing devices, and particularly relates to a squeezing coarse cloth for a squeezing portion. The squeezing coarse cloth for the squeezing portion comprises at least two layers of coarse layers, a first coarse layer and a second coarse layer are overlapped with each other, and are connected with each other through banding threads. The first coarse layer and the second coarse layer are both non-textile structure coarse layers formed by textile fibers. The total thickness of the first coarse layer and the second coarse layer is 3 mm to 4 mm. The total thickness of the first coarse layer and the second coarse layer is 3.5 mm. The squeezing coarse cloth for the squeezing portion adopting two layers of coarse layers to overlap to be the coarse cloth of the squeezing portion, the dehydration efficiency of the squeezing portion is enabled to be improved, a repeated wetting phenomenon can be prevented from occurring, compared with the prior art, the dryness of the wet paper of a squeezing exit is improved by 1 %, the paper injection difficulty of the wet paper is reduced, wrinkling and knurling and other problems of the paper in the squeezing portion can be reduced, product quality is effectively improved, and the squeezing coarse cloth for the squeezing portion is suitable for the production of high-strength corrugating medium paper.
Description
Technical field
The utility model relates to the papermaking press equipment technical field, specifically, relates to a kind of press section squeezing felt-cloth.
Background technology
In paper technology, wet web enters pressed zone after leaving the district that is shaped, in pressed zone a kind of papermaking fabric is arranged, we are referred to as " press felt or squeezing felt-cloth ", squeezing felt-cloth is the endless fabric, and squeezing felt-cloth is between one or more groups pressure roller, with certain speed round and round, remove unnecessary moisture in the wet web from the pressure of pressure roller, and strengthen removal ability to moisture unnecessary in the wet web by squeezing felt-cloth.
When producing high-strength corrugating medium (high concora crush paper), because anterior molding procedure adopts the specially-shaped net, so that fiber stays rate to improve, paper strength increases, but increased press section dehydration difficulty, press section should improve the mass dryness fraction of l Water Paper as far as possible, to reduce the paper injection difficulty of l Water Paper page or leaf, reduces page and produces the problems such as discounting embossing at press section.
Summary of the invention
The utility model has overcome defective of the prior art, a kind of press section squeezing felt-cloth is provided, and the dewatering efficiency of its energy Effective Raise press section improves squeezing outlet l Water Paper mass dryness fraction, reduce the paper injection difficulty of l Water Paper page or leaf, reduce page and produce the problems such as discounting embossing at press section.
The purpose of this utility model is realized by following technical scheme:
A kind of press section squeezing felt-cloth comprises two-layer at least batt, and the first batt and the second batt overlap each other, and described the first batt and the second batt are linked together by bounding wire.
Further, described the first batt and the second batt all are the batt of the non-textile structural that is made of textile fabric.
Further, the gross thickness of described the first batt and the second batt is 3mm to 4mm.
Further, the gross thickness of described the first batt and the second batt is 3.5mm.
The beneficial effects of the utility model are:
The utility model adopts two-layer batt stack as press section felt, so that the press section dewatering efficiency improves, prevent heavy moistening phenomenon, the l Water Paper mass dryness fraction of squeezing outlet more originally promoted about 1%, reduced the paper injection difficulty of l Water Paper page or leaf, reduced page and produced the problems such as discounting embossing at press section, Effective Raise product quality, be applicable to produce high-strength corrugating medium.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not consist of to restriction of the present utility model, in the accompanying drawings:
A kind of press section of Fig. 1 the utility model cross-sectional view of squeezing felt-cloth.
In Fig. 1, include:
The first batt 1, the second batt 2, bounding wire 3.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of press section squeezing felt-cloth comprises two-layer at least batt, and the first batt 1 and the second batt 2 overlap each other, and the first batt 1 and the second batt 2 are linked together by bounding wire 3.Multilayer batt dewatering efficiency is high.
The first batt 1 and the second batt 2 prevent from producing the problems such as embossing on the page surface for the batt of the non-textile structural that is made of textile fabric.
The gross thickness of the first batt 1 and the second batt 2 is 3.5mm, and enough thickness is applicable to high-strength corrugating medium squeezing process, and dewatering efficiency improves.Press section outlet mass dryness fraction improves.
The air permeability of squeezing felt-cloth is 60 CFM to 70CFM, and air permeability is good, and draining is smooth and easy, reduces the heavy moistening phenomenon of page, has improved squeezing exit web dryness.
It should be noted that at last: above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be stated scheme to the skill that aforementioned each embodiment puts down in writing and make amendment, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (4)
1. press section squeezing felt-cloth, it is characterized in that: comprise two-layer at least batt, the first batt and the second batt overlap each other, and described the first batt and the second batt are linked together by bounding wire.
