Problems solved by technology

[0004] But the above-mentioned bobbin paper production process has the following defects: the above-mentioned starch is sprayed on the paper by spraying in the process of adding starch, and the large paper width is relatively large, requiring several nozzles at the same time During operation, the spraying areas of several nozzles may overlap or have gaps. Such a process will lead to uneven feeding of starch, which will affect the production quality of paper.

Embodiment 1

[0045] A bobbin paper production process is characterized in that comprising the steps:

[0046] (1) Put recycled pulp from papermaking into the coarse stock tank after high-concentration desanding and disc grinding;

[0047] (2) After the waste paper is pulverized by a pulper and high-concentration desanding, it is also put into the coarse stock tank;

[0048] (3) The coarse stock in the coarse stock tank is separated by a fiber separator;

[0049] (4) After the fiber separator separates, the coarse pulp is medium-concentrated and sand-removed;

[0050] (5) Raw materials are finely screened and concentrated after medium-concentration desanding;

[0051] (6) After concentration, the raw material is put into the concentration pool;

[0052] (7) The raw materials in the concentration pool are put into the finished product pool after disc grinding;

[0053] (8) The raw materials of the finished product pool are transferred to the forebay pool, and papermaking sludge is added ...

Embodiment 2

[0063] refer to figure 1 , is a bobbin paper production equipment disclosed in the present invention and used in the first embodiment above, including a desander, a screening machine, a fiber separator and a paper machine (a desander, a screening machine, a fiber separator and a paper machine It is the prior art, not shown in the figure), the amylose feeding device 1 is arranged at the rear section of the press section of the paper machine, and the amylose feeding device 1 includes a frame 2, and the frame 2 is provided with a container for holding Put the feeding chute 3 of the amylose solution, the frame 2 is provided with the upper rubber roller 4 and the pressing roller 20 in rotation, the upper rubber roller 4 is in contact with the lower surface of the paper 30, and the upper rubber roller 20 is in contact with the upper surface of the paper 30. Surface contact, the upper rubber roller 4 is driven by a motor, and during the rotation of the upper rubber roller 4, the mate...

Abstract

The invention discloses a bobbin paper manufacturing process and production equipment thereof, and the bobbin paper manufacturing process comprises the following steps: feeding a papermaking forebay raw material by a feeding system, wherein a water repellent agent is added in the feeding process, by a flow conveying system, conveying the raw materials to a net part of a papermaking machine, addinga dry strength agent into the net part, treating the raw materials by a paper machine pressing part, mixing water and amylose to prepare a mixed solution, adding the mixed solution into a feeding tank, continuously heating the solution in the feeding tank, feeding the mixed solution between layers of a paper in a gluing roller coating manner, and uniformly scraping the material on a gluing rollerthrough a uniform scraping mechanism in the rotating process of the gluing roller, pre-drying the raw materials through a pre-drying part of the papermaking machine, sizing the paper by a sizing partof the papermaking machine, drying the raw materials by a rear drying part of the papermaking machine, and reeling a finished paper. According to the bobbin paper manufacturing process, amylose feeding is more uniform, and the production quality of paper is improved.

Description

technical field [0001] The invention relates to the technical field of bobbin paper manufacturing, in particular to a bobbin paper manufacturing process and production equipment thereof. Background technique [0002] Bobbin paper is an industrial technical paper used by chemical fiber equipment factories in the textile industry. It can be used to make filament high-speed spinning cores. It not only requires high dry strength, wet strength, smoothness and wear resistance, but also must have the characteristics of oil resistance and water resistance, and it is required to be lint-free, non-deformed, Do not burst. Based on the above characteristics, bobbin paper is required to have certain physical strength and high quantitative. [0003] The Chinese patent with the announcement number: CN201310285650.0 discloses a bobbin paper production process, which is characterized in that it includes the following steps: (1) putting recycled pulp from papermaking into the coarse stock t...
